truths:
- "A federation removal issued while an auto-sync pass is in flight leaves the peer removed — a sync's pre-removal node-list snapshot can no longer re-save the removed peer (FED-01 adjacency edge)"
- "Two concurrent federation node writes both persist — neither silently loses the other's update (the lost-update class behind the reported 'removed nodes reappear' symptom)"
- "Removing the last remaining federated node succeeds, leaves an empty node list, and returns Ok with an empty Vec (FED-01 empty edge)"
- "A removal whose tombstone write fails returns Err to the caller instead of reporting success (FED-01 failure-surfacing)"
- "The tombstone is durably written before the filtered node list is saved, so an interruption between the two never resurrects the removed peer (FED-01 ordering edge)"
- "A partially-written federation node list can never be observed by a concurrent reader — the list is written to a sibling temp file and renamed into place"
prohibitions:
- statement: "Removing a federation node MUST NOT delete or destroy that peer's local data — no app data directory under /var/lib/archipelago, no mesh message history, no credential store is erased by unfederating; removal revokes trust, it never destroys operator data"

pattern: "FEDERATION_STORE_LOCK"
---
<objective>
Close the concurrency race that lets a removed federation node come back: serialize every
read-modify-write against `federation/nodes.json` behind one async lock, and make the node-list
write atomic.
Purpose: FED-01 — "removing a federation node sticks" is the reason this phase exists. RESEARCH.md
identifies an unlocked read-modify-write on `federation/nodes.json` as the primary suspect: the 90s
auto-sync loop, the 1800s auto-sync loop, `federation.sync-state`, and `federation.remove-node` all
load → mutate → save the same file with zero coordination, so a sync task holding a pre-removal
snapshot silently re-saves the peer the operator just removed — with no error logged anywhere.
Output: `federation/storage.rs` with a module-level `FEDERATION_STORE_LOCK`, inner/outer function
split to avoid re-entrancy deadlock, an atomic temp-file+rename node-list write, and three new
regression tests that fail without the lock.

- `core/archipelago/src/federation/storage.rs` — the whole file (532 lines). Note in particular:
`load_nodes` (L51), `record_peer_transport` (L120), `save_nodes` (L149), `add_node` (L161,
calls `untombstone_did`), `remove_node` (L180, calls `tombstone_did`), `tombstone_did` (L214),
`untombstone_did` (L237), `set_trust_level` (L256), `update_node` (L272), `update_node_state`
(L292), and the existing `#[cfg(test)] mod tests` (L341) with its `make_node(did, onion)`
helper and `tempfile::tempdir()` convention.
- `core/archipelago/src/update.rs` lines 25-40 — `UPDATE_OP_LOCK`, the in-repo precedent for
"two async call sites race on one on-disk resource". Copy its doc-comment style (name the
concrete historical incident, then state the acquisition policy).
- `.planning/phases/01-federation-mesh-hardening/01-PATTERNS.md` — section "Async static lock
for a racy on-disk resource" and "core/archipelago/src/federation/storage.rs (locking fix)".
</read_first>
<behavior>
- `test_concurrent_writes_do_not_lose_updates`: under `#[tokio::test(flavor = "multi_thread", worker_threads = 4)]`,
seed one node, then `tokio::join!` an `add_node(B)` with a `set_trust_level(A, Observer)`;
afterwards `load_nodes` returns 2 nodes AND node A's trust level is Observer. Without the
lock one of the two writes is lost.
- `test_remove_survives_concurrent_state_sync`: under the multi-thread flavor, loop 50 times:
fresh tempdir, seed nodes A and B, `tokio::join!(remove_node(A), update_node_state(A, snapshot))`,
then assert `load_nodes` contains no entry whose `did` is A and `load_removed_dids` contains A.
Without the lock this reliably fails within 50 iterations.
- `test_remove_last_node_leaves_empty_list`: seed exactly one node, remove it, assert the
returned Vec is empty, `load_nodes` returns an empty Vec (not an error), and the DID is
tombstoned.
</behavior>
<action>
Write the three tests FIRST in the existing `mod tests` block and confirm they fail (run the
verify command and capture the failure) before writing the fix.
Then add at module scope, immediately after the existing `use` block:
`static FEDERATION_STORE_LOCK: tokio::sync::Mutex<()> = tokio::sync::Mutex::const_new(());`
with a doc comment that names the failure it prevents — a `federation.remove-node` RPC racing
the 90s auto-sync pass, whose pre-removal `load_nodes` snapshot re-saves the removed peer with
no error logged — and states the acquisition policy: acquire with `.lock().await`, never
`try_lock`. Reject-on-contention is wrong here: a rejected federation write reproduces the very
lost-write symptom the lock exists to stop, unlike `update.rs` where rejecting a second
concurrent download is the desired UX.
Restructure so no public function can deadlock on itself. For each function that both takes the
lock and calls another locking function, extract the body into a private `*_inner` fn that does
NOT acquire, and make the public fn a thin wrapper: acquire the guard, call the inner(s), drop.
Required inner fns for this task: `load_nodes_inner`, `save_nodes_inner`, `tombstone_did_inner`,
`untombstone_did_inner`. `remove_node` (which calls `tombstone_did`) and `add_node` (which calls
`untombstone_did`) must call the `*_inner` variants under a single held guard so tombstone +
node-list save are one critical section.
Convert the node-list write in `save_nodes_inner` to atomic replace: serialize to a sibling path
formed by appending a `.tmp` suffix to the resolved nodes file path in the same directory, write
it with `tokio::fs::write`, then `tokio::fs::rename` it onto the real path. Keep the existing
`.context(...)` error strings so callers' messages are unchanged. Same-directory rename is
required — a cross-filesystem rename is not atomic.
In THIS task route `load_nodes`, `save_nodes`, `remove_node`, `tombstone_did`,
`untombstone_did`, and `update_node_state` through the lock. The remaining mutators are Task 2.
Preserve `remove_node`'s existing ordering exactly: the retain/`bail!`-on-not-found check, then
the tombstone write with its failure propagated via `.context("persist removal tombstone")?`,
then the node-list save. Do not weaken that ordering or its error propagation.
Build gotcha from CLAUDE.md: if the build hits `rust-lld: undefined hidden symbol`, that is
incremental-cache corruption — re-run with `CARGO_INCREMENTAL=0`.

Add `test_remove_errors_when_tombstone_write_fails`: seed a node, then make the tombstone write
fail by pre-creating the removed-nodes path as a directory (a directory cannot be replaced by a
file write), call `remove_node`, and assert the result is `Err` AND that `load_nodes` still
contains the node — a removal whose tombstone never landed must not have half-applied. This is
the FED-01 "a failed removal surfaces an error instead of silently no-opping" criterion at the
storage layer.

## Trust Boundaries

|----------|-------------|
| federated peer → `federation::sync` → node store | A remote peer's state snapshot crosses into local persisted trust state |
| operator RPC (`federation.remove-node`) → node store | An authenticated local operator action mutates trust membership |
| process → `federation/nodes.json` on disk | Multiple concurrent async tasks write one file; a crash can leave it partial |

| T-01-02 | Elevation of Privilege | a removed (untrusted) peer regaining federation membership via the race | high | mitigate | Same lock; plus the pre-existing tombstone check in `merge_transitive_peers` and `handle_federation_peer_joined` is left intact and re-verified by `cargo test -p archipelago federation` |
| T-01-03 | Denial of Service | a partial `nodes.json` write on crash making the node list unreadable | medium | mitigate | Atomic temp-file + same-directory `fs::rename` in `save_nodes_inner` (Task 1) |
| T-01-04 | Denial of Service | lock contention stalling the federation RPC surface | low | accept | Federation writes are infrequent (90s loop + operator actions); `.lock().await` queues rather than rejects, and every critical section is a bounded file read+write |

# Phase 01 Plan 01: Serialize the federation node store and make removal stick (FED-01) Summary
Closed the concurrency race that let a removed federation node reappear: every load-mutate-save
cycle in `federation/storage.rs` is now serialized behind one module-level `FEDERATION_STORE_LOCK`,
the node-list write is atomic (temp file + same-directory rename), and a tombstone-write failure
now surfaces as an `Err` instead of a silent no-op.
## What Was Built
- `FEDERATION_STORE_LOCK: tokio::sync::Mutex<()>` (module-level static, `const_new`), documented
with the concrete failure it prevents (a `federation.remove-node` RPC racing the 90s auto-sync
loop's stale pre-removal snapshot).
- `load_nodes_inner` / `save_nodes_inner` / `tombstone_did_inner` / `untombstone_did_inner`:
lock-free bodies so `remove_node` (tombstone + save) and `add_node` (untombstone + save) can
each hold the guard across their whole multi-step critical section without self-deadlocking
(`tokio::sync::Mutex` is not re-entrant).
- Every public mutator now routes through the lock: `load_nodes`, `save_nodes`, `add_node`,
`remove_node`, `tombstone_did`, `untombstone_did`, `set_trust_level`, `update_node`,
`update_node_state`, `record_peer_transport` — 10 `.lock().await` call sites total.
- `save_nodes_inner` writes atomically: serialize to `nodes.json.tmp` in the same directory,
then `fs::rename` onto `nodes.json` — a crash mid-write can never leave a partial file for a
concurrent reader.
- Four new regression tests in `federation::storage::tests`:
- `test_concurrent_writes_do_not_lose_updates` — races `add_node` against `set_trust_level`
via real `tokio::spawn` tasks, 40 iterations; asserts both writes persist.
- `test_remove_survives_concurrent_state_sync` — races `remove_node` against a 12-task burst
of `update_node_state` calls, 30 iterations; asserts the removed DID stays removed and
tombstoned.
- `test_remove_last_node_leaves_empty_list` — removing the sole federated node returns/loads
an empty `Vec`, not an error.
- `test_remove_errors_when_tombstone_write_fails` — pre-creates `removed-nodes.json` as a
directory so the tombstone write fails; asserts `remove_node` returns `Err` AND the node
list is untouched (no half-applied removal).
## Task Execution Note (continuation)
Task 1 (the tracer: lock + atomic write + first three tests) was already committed in a prior
session (`2f99db5e`, 2026-07-30) and pushed. This session picked up as a continuation: verified
Task 1's commit and tests were real and green, then completed Task 2 — routing
`record_peer_transport` and `update_node` through the lock (they still called the public,
separately-locked `load_nodes`/`save_nodes` instead of the `*_inner` pair under one guard) and
adding the tombstone-failure test. No SUMMARY/STATE/ROADMAP update had been done for this plan
before this session; that gap is closed by this document.
## Pre-fix Failure Evidence (Task 1, historical)
Task 1's commit message (`2f99db5e`) records that both `test_concurrent_writes_do_not_lose_updates`
and `test_remove_survives_concurrent_state_sync` were proven fail-first before the lock existed:
using real `tokio::spawn` tasks (not just `tokio::join!`, since `remove_node`'s extra tombstone
I/O hop structurally biases a simple 2-task race toward the safe ordering) reliably reproduced
both the lost concurrent write and the removed-node-reappears bug pre-fix. This session did not
re-run the pre-fix reproduction (the fix and lock already exist on disk); the historical evidence
is carried forward from the Task 1 commit message since no separate SUMMARY captured it at the
time.
## Verification
- `cd core && cargo test -p archipelago federation::storage` — **14/14 passed, 0 failed**
(11 pre-existing + 3 new from Task 1's earlier commit + this session's
`test_remove_errors_when_tombstone_write_fails`).
- `cd core && cargo build -p archipelago` — succeeds, no new warnings in `federation::storage`
(no dead-code warnings on any `*_inner` fn — confirms every mutator is wired through).
- Acceptance-criteria greps: `FEDERATION_STORE_LOCK` count 16, `.lock().await` count 10 (≥9
required), `tokio::sync::Mutex::const_new` count 1, `fs::rename` count 1, all four new test
function names present, `flavor = "multi_thread"` present.
- **`cd core && cargo test -p archipelago` (full suite) — NOT clean this session.** The
workspace test binary fails to *compile*, but the failure is in
`core/archipelago/src/api/rpc/package/install.rs:592` (a tuple-pattern-vs-`Result` mismatch on
a `.await?` line marked "Not Committed Yet" by `git blame` at the time of this run) — a file
this plan never touches, mid-edit by a different, concurrent agent session in this shared
checkout (`git status` at commit time showed `install.rs`, `config.rs`, `dependencies.rs`,
`secrets.rs`, and several `neode-ui` files dirty, none authored by this plan). This is the
exact shared-tree hazard the task's hard constraints warn about, not a regression from this
plan's change. `federation::storage`'s own test binary (scoped `cargo test -p archipelago
federation::storage`) compiles and passes clean, and `cargo build -p archipelago` (non-test)
also succeeds — the compile error is specific to the test-cfg path in `install.rs`, unrelated
to `storage.rs`. Recorded honestly per the task's own instruction rather than declared green;
re-run `cargo test -p archipelago` once the other in-flight session's `install.rs` edit lands
or is reverted.
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - blocking issue, scope-bounded] Full-suite verification blocked by a concurrent
agent's uncommitted edit in an unrelated file**
- **Found during:** final verification step (`cargo test -p archipelago`)
- **Issue:** `install.rs:592` fails to compile (tuple destructure not wrapped in `Ok(...)`
against a function that now returns `Result`), per `git blame` an uncommitted, in-progress
edit by a different session.
- **Fix:** None applied — out of this plan's scope per the SCOPE BOUNDARY rule (issue not caused
by this plan's changes, and touching a file another agent is actively editing risks clobbering
their work). Logged here and left for that session to resolve.
- **Files modified:** none (no fix applied)
No other deviations — the rest of this plan (routing `record_peer_transport`/`update_node`
through the lock, adding the failure test) executed exactly as written in Task 2's `<action>`.
## Known Stubs
None.
## Self-Check: PASSED
- `core/archipelago/src/federation/storage.rs` — FOUND (modified, contains `FEDERATION_STORE_LOCK`,
`record_peer_transport`, `update_node`, `test_remove_errors_when_tombstone_write_fails`).
- Commit `4b5367eb` — FOUND in `git log --oneline`.
- Commit `2f99db5e` (Task 1, prior session) — FOUND in `git log --oneline`.
- Push to `gitea-ai main` — confirmed (`bc9a210c..4b5367eb main -> main`).

and the message-mutation calls actually mutate demo state instead of returning a bare acknowledgement.
Purpose: FED-04. Attachment-send parity already landed on main (`c2ce71c6`) — `mesh.send-content-inline`
/ `mesh.send-content` / `mesh.fetch-content` / `mesh.transport-advice` now mirror the daemon's tier
logic. RESEARCH.md and a fresh cross-reference of `neode-ui/src/**` against `mock-backend.js` show
what remains: **12 methods the UI calls that have no case at all** (they fall through to a
`Method not found` error the frontend swallows in `try/catch`), and **six ack-only stubs** that
never touch the demo message store, so reactions/edits/deletes silently do not render on the demo.
Output: those gaps closed, plus a repeatable parity harness so this class of drift is caught by a
command instead of by squinting at the browser console.

- `neode-ui/mock-backend.js` lines 4300-4500 — the `mesh.transport-advice` case and the comment
block above it (the house convention: mirror the daemon and cite the source file), the
`mesh.send-content-inline` case for how a handler mutates `currentStore().mesh.dynamic`, and
the ack-only stub block at the end of the mesh cases.
- `neode-ui/mock-backend.js` lines 5495-5530 — the per-session store shape (`mesh: { dynamic: [], blobs: {} }`)
and `currentStore()`.
- `neode-ui/mock-backend.js` lines 80-90 and 5710-5730 — the `PORT` constant and the `server.listen` call.
- `core/archipelago/src/api/rpc/mesh/typed_messages.rs` — `handle_mesh_contacts_list` (from L1218)
and `handle_mesh_contacts_save` (from L1253): the real merge of `state.contacts` (a
`ContactEntry` map with `alias`, `notes`, `pinned`, `blocked`) over `state.peers`, and the
exact response shape the UI consumes.
- `neode-ui/src/api/rpc-client.ts` lines 795-820 — the `mesh.contacts-list` / `mesh.contacts-save`
wrappers and their params shape.
- `neode-ui/src/views/Mesh.vue` — the two call sites (on mount, and on peer rename) to confirm
which response fields are read.
</read_first>
<action>
Add a `contacts` bucket (a plain object keyed by peer contact id) to the per-session mock store
alongside the existing `dynamic` and `blobs` keys.
Implement `mesh.contacts-save`: accept the same params the daemon's handler takes, upsert
`{ alias, notes, pinned, blocked }` for the given peer key into the session `contacts` bucket,
and return the same result shape the real handler returns. Implement `mesh.contacts-list`:
merge the session `contacts` bucket over the demo's `mesh.peers` list exactly as the daemon
merges `state.contacts` over `state.peers`, and return the same field names. Follow the house
convention already used above `mesh.transport-advice`: a comment naming
`typed_messages.rs handle_mesh_contacts_list` / `handle_mesh_contacts_save` as the source of
truth, so a future reader knows where to re-check parity.
Change the hardcoded listen port to read an env override first, defaulting to the existing
value, so a harness can bind an ephemeral port without colliding with a running dev preview.
Use the env var name `MOCK_BACKEND_PORT`.
Create `neode-ui/scripts/mock-rpc-parity.mjs` with two stages and a non-zero exit on any failure:
(1) STATIC — scan `neode-ui/src/**` for every `'mesh.<verb>'` / `'federation.<verb>'` string
literal, scan `mock-backend.js` for every `case '<method>':`, and report methods called by the UI
with no mock case. Print the offending method names. (2) LIVE — spawn `node mock-backend.js`
with `MOCK_BACKEND_PORT` set to a free port, poll `/rpc/v1` until ready (bounded ~10s), then POST
a scripted JSON-RPC sequence and assert on the responses: `mesh.contacts-save` with an alias,
then `mesh.contacts-list` returns that alias for that peer. Kill the child in a `finally` block.
Do not use `|| echo`-style fallbacks anywhere in the script or its npm wiring — a failed spawn,
a failed fetch, or a missing field must propagate as a non-zero exit, never a passing run that
measured nothing.
Register it as the `test:mock-parity` npm script in `neode-ui/package.json`.
In this task the STATIC stage is expected to still report the other missing methods; make it
print them and exit non-zero only when the LIVE stage fails or when a method from an explicit
`KNOWN_GAPS` array is missing. Task 2 empties `KNOWN_GAPS` to zero entries.

- The STATIC-stage output from Task 1 — the authoritative live list. As of planning it is:
`mesh.clear-all`, `mesh.schedule-message`, `mesh.list-scheduled`, `mesh.cancel-scheduled`,
`mesh.assistant-status`, `mesh.assistant-configure`, `federation.nodes`,
`federation.dwn-status`, `federation.notify-did-change`, `federation.cancel-request`.
- `core/archipelago/src/api/rpc/dispatcher.rs` lines 390-440 — the real handler names each of
these methods dispatches to, so the mock mirrors the right handler.
- `neode-ui/mock-backend.js` — the existing `federation.list-nodes`, `federation.list-pending-requests`,
`federation.approve-request`, and `federation.reject-request` cases, for the response shapes
the sibling federation methods must match.
</read_first>
<action>
Add a case for each remaining method, mirroring the real handler's response shape (read the
Rust handler named by the dispatcher before writing each one) and citing it in a comment the way
the contacts handlers do.
Behavioral requirements, not bare acknowledgements: `mesh.clear-all` empties the session
`dynamic` message array; `mesh.schedule-message` pushes into a new session `scheduled` bucket
and returns the created entry's id; `mesh.list-scheduled` returns that bucket;
`mesh.cancel-scheduled` removes by id and reports whether an entry was actually removed;
`federation.nodes` returns the same node array `federation.list-nodes` returns (the UI treats
them as aliases); `federation.cancel-request` removes the request from the pending-requests
bucket the existing approve/reject cases operate on.
Then set the harness's `KNOWN_GAPS` array to empty so the STATIC stage exits non-zero on ANY
UI-called method without a mock case, and extend the LIVE stage with one assertion per newly
stateful method that has observable state: schedule a message then list it and assert it is
present; cancel it and assert it is gone; clear-all then read `mesh.messages` and assert the
dynamic messages are gone.

<read_first>

`mesh.send-reply`, `mesh.send-read-receipt`, `mesh.edit-message`, `mesh.delete-message`,
`mesh.forward-message`, `mesh.send-channel` (currently a shared bare-acknowledgement case),

read-receipt / forward handlers, and lines 1065-1180 — edit / delete. Note the stable
`sender_pubkey` + `sender_seq` message key these operate on, not the local `id`.
- `core/archipelago/src/mesh/types.rs` lines 139-180 — the `MeshMessage` field set the demo
objects must match (`id`, `direction`, `peer_contact_id`, `peer_name`, `plaintext`,
`timestamp`, `delivered`, `encrypted`, `transport`, `message_type`, `typed_payload`,
`sender_pubkey`, `sender_seq`).
- `neode-ui/src/views/Mesh.vue` and `neode-ui/src/stores/mesh.ts` — how the UI reads reactions,
edited text, and deleted markers, so the mutated shape is the one that renders.
</read_first>
<action>
Split the shared acknowledgement case into individual cases that mutate `currentStore().mesh.dynamic`:
`mesh.send-reaction` — locate the target message by the same key the daemon uses and append or
toggle the emoji in its reactions collection. `mesh.send-reply` — push a new message whose
payload carries the replied-to message key, so the UI renders the quote block.
`mesh.send-read-receipt` — mark the target message read. `mesh.edit-message` — replace the
target's text and set the edited marker the UI reads. `mesh.delete-message` — apply the same
deletion representation the daemon applies (tombstone marker vs removal — read the handler and
mirror it, do not choose independently). `mesh.forward-message` — push a copy addressed to the
destination peer. `mesh.send-channel` — push a channel-addressed message.
Leave `mesh.refresh` and `mesh.reboot-radio` as acknowledgements — the daemon's handlers have no
message-store effect either, so mirroring means leaving them alone. Add a comment on that pair
stating why they remain acknowledgements, so a later reader does not "fix" them into divergence.
Extend the harness's LIVE stage: send a message, react to it, and assert `mesh.messages` shows
the reaction; edit it and assert the text changed and the edited marker is set; delete it and
assert the daemon-matching representation; forward it and assert a copy exists for the
destination peer.

## Planner Assumptions (flagged, unresolved)
- **FED-04 / spec-less probe, category `unclassified`:** the probe could not classify an edge for
FED-04, and no acceptance criterion was invented for it. The parity harness covers the *known*
drift class (missing handler, non-mutating handler); it does NOT cover response-shape drift where
a mock case exists and returns a differently-shaped success object than the daemon. That residual
class is surfaced here rather than silently dropped, and is a candidate finding for the FED-03
review in plan 01-07.
<threat_model>
## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| browser → mock backend `/rpc/v1` | Developer-local demo surface; accepts unauthenticated JSON-RPC on a loopback-bound dev port |
| harness child process → mock backend | The parity script spawns and drives the mock on an ephemeral port |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-05 | Spoofing | mock backend impersonating real daemon behavior in a way that hides a real-node bug | medium | mitigate | Every mirrored handler cites the daemon file and line range it mirrors; the parity harness asserts observable state transitions, not acknowledgements |
| T-01-06 | Information Disclosure | mock backend binding a non-loopback interface on a developer machine | low | accept | Pre-existing `0.0.0.0` bind is unchanged by this plan; the mock serves only synthetic demo data and ships in no release artifact |
| T-01-07 | Tampering | the parity harness leaving an orphaned server process holding a port | low | mitigate | The child is killed in a `finally` block and the acceptance criteria require two consecutive clean runs |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | No packages are added by this plan — the harness uses only Node built-ins (`node:child_process`, `fetch`, `node:fs`). If any dependency becomes necessary, stop and run the Package Legitimacy Gate before installing |

The overlay makes edit/delete observable on seeded messages too, not just ones sent this session."
- "Delete tombstones in place (plaintext '🗑 message deleted', typed_payload { deleted: true }, message_type 'delete') because that is precisely what mesh/mod.rs apply_local_delete does — it does not remove the row. A comment says so, since 'simplifying' it to a splice would be a silent divergence."

# Phase 1 Plan 2: Demo/Real Mesh RPC Parity (FED-04) Summary
**Closed the ten mesh/federation methods the demo answered with "Method not found", made the six ack-only chat mutations actually mutate demo state, and replaced "squint at the browser console" with a single command that fails when the demo drifts.**
## Performance
- **Duration:** ~75 min
- **Completed:** 2026-08-01
- **Tasks:** 3/3
- **Files modified:** 3 (mock backend, new harness, package.json)
## Accomplishments
- Ten new handlers, each citing the Rust it mirrors: `mesh.contacts-list`/`-save` (typed_messages.rs), `mesh.clear-all` (status.rs), `mesh.schedule-message`/`list-scheduled`/`cancel-scheduled` (assistant.rs + scheduler.rs), `mesh.assistant-status`/`-configure` (assistant.rs), `federation.cancel-request` and `federation.notify-did-change` (federation/handlers.rs).
- The chat mutations are no longer bare acknowledgements. Reactions, replies and read-receipts push typed messages carrying the `{ sender_pubkey, sender_seq }` target key the UI's `reactionIndex`/`replyTargetPreview` read; edits rewrite the text and set `edited_at`; deletes tombstone in place; forwards copy to the destination peer; channel sends are channel-addressed.
- `mesh.peers` and `mesh.contacts-list` share one `DEMO_MESH_PEERS` list, and the peer with no `pubkey_hex` is omitted from contacts exactly as the daemon's `if let Some(pk)` guard omits it.
- `scripts/mock-rpc-parity.mjs` runs a static cross-reference then boots the mock on an ephemeral port and drives 17 live assertions. No `|| fallback` escapes anywhere in it — a failed spawn or fetch fails the run rather than producing a green run that measured nothing.
## Task Commits
1. **Tasks 1 + 2: contacts round-trip, harness, and the ten missing methods** — `b8979f36` (feat)
2. **Task 3: make the message-mutation stubs mutate demo state** — committed with this SUMMARY
## Deviations from Plan
### The STATIC scan matches call syntax, not every string literal — and the plan's gap list had two false positives
**Found during:** Task 1, building the static cross-reference
**Issue:** The plan specifies scanning `src/**` for "every `'mesh.<verb>'` / `'federation.<verb>'` string literal". That over-reports badly: `Mesh.vue` and `Federation.vue` use the same dotted names as **resource-cache keys** (`key: 'mesh.self-did'`, `key: 'mesh.transport-status'`, `key: 'federation.nodes'`, `key: 'federation.dwn-status'`), and `stores/sync.ts` invalidates by the same strings. None are RPC methods. A literal scan reports 18 gaps where 10 exist.
Two of those phantoms — **`federation.nodes` and `federation.dwn-status`** — are named in the plan's own Task 2 gap list. They are not RPC methods and the daemon's dispatcher has no such routes; `Federation.vue` uses them purely as cache keys. Implementing them would have added demo-only endpoints the real node does not serve, which the plan's own transparency prohibition forbids.
**Resolution:** The scan matches `method:\s*['"]…['"]`, i.e. an actual call site. The gap list becomes exactly the 10 real methods, `KNOWN_GAPS` is empty, and the harness is genuinely failable — proven by disabling a case and watching it exit 1.
**Files modified:** `neode-ui/scripts/mock-rpc-parity.mjs`
### Added an outbound pending request to the demo seed
**Found during:** Task 2, implementing `federation.cancel-request`
**Issue:** The daemon only permits cancelling an **outbound** request in **sent** state. The demo seed contained a single inbound/pending request, so a faithful handler could only ever return an error and the cancel path was unexercisable.
**Resolution:** Added `preq-demo-out-1` (outbound, state `sent`) to `pendingPeerRequests`. The handler stays faithful — it still rejects non-outbound and non-sent requests with the daemon's own message.
**Files modified:** `neode-ui/mock-backend.js`
### Edits/deletes use an overlay rather than in-place mutation
**Found during:** Task 3
**Issue:** `mesh.messages` rebuilds its seeded message array on every read, so mutating "the message" in place would be lost immediately for any seeded message and only work for messages sent in this session.
**Resolution:** A per-session `overrides` map keyed by `sender_seq`, applied over the merged list on read. This matches the daemon's matching rule (own-Sent message by `sender_seq`) and makes edit/delete observable for seeded messages too.
**Files modified:** `neode-ui/mock-backend.js`
## Known Stubs
`mesh.assistant-status` reports `ollama_detected: false`, `claude_available: false` and an empty model list. That is the honest answer for a browser demo with no local model — the UI's "not detected" path is what a visitor should see, and fabricating a model list would be exactly the demo-only divergence this plan's prohibition forbids.
## Threat Flags
None. This plan touches only the demo/mock backend and a dev-time harness; no production code path, endpoint or trust boundary is involved. The `T-01-SC` package-install threat does not apply — no dependencies were added (the harness uses only `node:` builtins and global `fetch`).
## Self-Check: PASSED
- CONFIRMED: `node --check mock-backend.js` exits 0
- CONFIRMED: `node scripts/mock-rpc-parity.mjs` exits 0 — 17 live assertions, 0 unhandled methods
- CONFIRMED: fail-first proof (disable a case → exit 1 naming it; restore → exit 0 twice in a row)
- CONFIRMED: each of the ten methods appears exactly once as a `case`
- CONFIRMED: `KNOWN_GAPS` is present and empty; `MOCK_BACKEND_PORT` honoured; `typed_messages.rs` cited twice
- CONFIRMED: `npm run test:mock-parity` registered in package.json

<objective>
Make the invoice/payment "paid" tick on-brand: the circle around the checkmark becomes the
screensaver ring with its outer EQ-segment lines, everywhere the paid tick appears.
Purpose: FED-06, locked by the user in CONTEXT.md — the paid-tick circle is the ScreensaverRing
style, applied consistently to every paid/success tick surface. RESEARCH.md flagged that a naive
drop-in overflows the modal card (the existing compact variant is 240-320px against a 96-112px
badge); 01-UI-SPEC.md resolved that by deciding on a new `badge` size variant rather than a
transform hack, and also recorded that `ScreensaverRing` has no `prefers-reduced-motion` guard at
all today — a real gap this phase must close.
Output: a third size variant plus a reduced-motion guard in the shared component, both paid-tick
call sites swapped, and component tests pinning the result.

<read_first>
- `neode-ui/src/components/ScreensaverRing.vue` — the whole file (about 115 lines): the
`withDefaults(defineProps<{ size?: ... }>())` union, the `sizeClass` computed, the two
existing size CSS classes with their `min-width: 768px` breakpoints and `--viz-radius`
custom properties, and the `segment-pulse` keyframes.
- `neode-ui/src/components/SendBitcoinModal.vue` lines 1-30 (the success pane markup: the
success-burst container, its three ripple span elements, and the core circle plus checkmark)
and lines 680-740 (the corresponding CSS block, including the existing
`@media (prefers-reduced-motion: reduce)` rule — copy that exact media-query syntax into
ScreensaverRing).
- `neode-ui/src/components/Screensaver.vue` — the existing `ScreensaverRing` + `ScreensaverLogo`
centred-absolute layering pattern (`position: relative` wrapper, `position: absolute; inset: 0`
inner content) to reuse for the checkmark core.
- `neode-ui/src/components/__tests__/BaseModal.test.ts` — the house vitest + `@vue/test-utils`
conventions for mounting a component in this repo.
- `.planning/phases/01-federation-mesh-hardening/01-UI-SPEC.md` — the "FED-06 Sizing Decision"
table (exact diameters and radii) and the "UI Considerations" rows for the paid-tick ring.
</read_first>
<behavior>
- `ScreensaverRing.test.ts`: mounting with `size="badge"` puts `viz-ring-badge` on the root
element; mounting with `size="compact"` still yields `viz-ring-compact`; the default mount
still yields `viz-ring-default`; the rendered segment count matches the `segmentCount` prop.
- `PaidTick.test.ts`: SendBitcoinModal driven into its payment-success state renders exactly one
`ScreensaverRing` with `size="badge"`, renders the checkmark core, and renders zero ripple
elements; the success amount text is unchanged.
</behavior>
<action>
Write both test files first and confirm they fail before implementing.
In `ScreensaverRing.vue`: widen the `size` prop union with a third member `'badge'`, extend
`sizeClass` to map it to `viz-ring-badge`, and add a `.viz-ring-badge` CSS rule following the
exact shape of the existing two — `width`/`height` 160px and `--viz-radius: 80px` at mobile,
then a `@media (min-width: 768px)` block with 192px and `--viz-radius: 96px`. Do not touch
`.viz-ring-default` or `.viz-ring-compact`; `Screensaver.vue` and `SystemDangerZone.vue` must
keep their current rendering.
Also inside `ScreensaverRing.vue`, add the missing motion guard so it applies to every variant:
a `@media (prefers-reduced-motion: reduce)` block that sets `animation: none` and a static
reduced opacity on `.viz-segment`. Use the same media-query syntax as the guard already present
in `SendBitcoinModal.vue` so the two read identically.
In `SendBitcoinModal.vue`'s payment-success pane: import `ScreensaverRing`, replace the three
ripple span elements with `<ScreensaverRing size="badge" />`, keep the existing core circle and
checkmark markup untouched, and wrap the pair in the Screensaver-style layering (a
`position: relative` container sized to the badge diameter, with the core absolutely centred over
the ring). Remove the ripple elements' now-dead CSS rules and their keyframes; keep the core and
checkmark rules, and keep the existing reduced-motion rule but drop the clause that referenced
the removed elements. Do not change the success amount numerals, the SENT copy, the Done button,
or any condition that decides when the success pane is shown.

## Planner Assumptions (flagged, unresolved)
- **FED-06 / spec-less probe, category `unclassified`:** the probe surfaced an unclassified edge for
FED-06 that no defensible acceptance criterion covers. Surfaced rather than dropped: the phase
requirement says the ring applies "everywhere the paid tick appears", and a repo-wide grep found
exactly two paid-tick surfaces (`SendBitcoinModal.vue`, `WalletScanModal.vue`). If a third
success-tick surface is added between planning and execution — or exists under markup this grep
did not match — it will not be covered by this plan. The FED-03 review in plan 01-07 re-runs the
grep as a check.

| T-01-08 | Spoofing | success pane rendered for a payment that has not settled | high | mitigate | This plan changes decoration only; the acceptance criteria forbid touching any condition that gates the success pane, and `npx vitest run` on the existing suites must stay green |

# Phase 1 Plan 3: On-Brand Paid Tick (FED-06) Summary
**Both paid-tick surfaces now render the screensaver's EQ-segment ring at a new modal-sized `badge` variant, and the shared ring component finally honours `prefers-reduced-motion` — a guard it had been missing for every variant, not just the new one.**
## Performance
- **Duration:** ~55 min
- **Completed:** 2026-08-01
- **Tasks:** 2/2
- **Files modified:** 5 (3 components, 2 new test files)
## Accomplishments
- `ScreensaverRing` gained a `badge` size (160px mobile / 192px from 768px up, with matching `--viz-radius` 80px / 96px) mapped through `sizeClass`, following the exact shape of the existing two variants. `default` and `compact` are untouched.
- The reduced-motion guard was added to the component itself, so the screensaver and SystemDangerZone call sites gain it as a side benefit — `01-UI-SPEC.md` had flagged its complete absence.
- `SendBitcoinModal`'s success pane swapped its three CSS ripple spans for the ring, keeping the emerald pop-in check and its draw animation; the dead `burst-ring*` rules and `burst-ripple` keyframes were removed and the reduced-motion rule updated to drop the clause referencing them.
- `WalletScanModal`'s plain `w-24` circle became the same composition, so both paid ticks are now literally the same markup shape.
- Two new suites (5 tests) pin the variant mapping, the segment count, and both call sites — including that the ripple elements are gone and the amount/SENT copy is unchanged.
## Task Commits
1. **Task 1: badge variant + SendBitcoinModal** and **Task 2: WalletScanModal** — committed together with this SUMMARY (both surfaces share the composition; splitting them would have committed a half-converted pair of paid ticks).
## Files Created/Modified
- `neode-ui/src/components/ScreensaverRing.vue` — `'badge'` added to the size union, `sizeClass` widened to an if-chain, `.viz-ring-badge` rule + 768px breakpoint, and the `prefers-reduced-motion` guard on `.viz-segment`.
- `neode-ui/src/components/SendBitcoinModal.vue` — `ScreensaverRing` import; success pane restructured to `.send-success-badge` > ring + centred `.send-success-burst`/`.burst-core`; ripple markup, `.burst-ring*` rules and `burst-ripple` keyframes deleted.
- `neode-ui/src/components/WalletScanModal.vue` — `ScreensaverRing` import; `.scan-success-badge` + `.scan-success-core` replacing the fixed circle and its `.success-ring` rule.
- `neode-ui/src/components/__tests__/ScreensaverRing.test.ts` — 3 tests.
- `neode-ui/src/components/__tests__/PaidTick.test.ts` — 2 tests, one per surface.
## Deviations from Plan
### Test assertions had to target the document, not the wrapper
**Found during:** Task 1, first green run
**Issue:** `wrapper.find('.burst-core')` returned nothing even though the markup rendered. `BaseModal` teleports its content to `document.body`, so the rendered nodes live outside the mounted wrapper's own root element. Component-tree queries (`findAllComponents`) still work, which is why the ring assertions passed while the DOM ones failed.
**Resolution:** DOM assertions switched to `document.querySelector(...)`, with an `afterEach` clearing `document.body` so one modal's teleported nodes cannot answer the next test's queries.
**Files modified:** `neode-ui/src/components/__tests__/PaidTick.test.ts`
### Auto-fixed: vue-tsc strict-null on indexed access
**Found during:** `npm run build`
**Issue:** `rings[0].props('size')` failed `vue-tsc` under `noUncheckedIndexedAccess` (TS2532) — the same class of failure commit `4a8925f0` fixed in `usePaidItemViewer.test.ts`.
**Resolution:** optional chaining (`rings[0]?.props('size')`), matching that commit's fix exactly.
**Files modified:** `neode-ui/src/components/__tests__/PaidTick.test.ts`
### Outstanding: the live dev-preview observation Task 2 asks for was NOT made
**Found during:** Task 2 verification
**Issue:** Task 2 requires confirming on a dev preview that neither ring is clipped by the modal card's scrolling container at a narrow and a desktop viewport. Reaching either success pane in a real browser requires an actually-settled payment; the built preview on `:4321` has no backend to settle one, and the running demo/dev servers in this tree belong to other sessions and are not to be disturbed.
**Resolution:** NOT resolved. Recorded honestly as deferred rather than claimed. The automated evidence (5 tests, `npm run build` green, `viz-ring-badge` present in the built bundle) covers structure but not appearance. The plan already consolidates the blocking human sign-off for this into **plan 01-07**, which is where the visual check belongs; the geometric argument (a 160px badge inside a `max-w-2xl` card, ~344px usable at a 390px viewport) says clipping is implausible, but it is not an observation.
**Files modified:** none
## Known Stubs
None.
## Threat Flags
None — presentational only. The plan's safety prohibition (the ring must never render success for an unsettled payment) is structurally satisfied: no success-gating condition was touched, only the markup inside an already-gated pane.
## Self-Check: PASSED
- FOUND: `viz-ring-badge` in `ScreensaverRing.vue` (3 occurrences: mapping + rule + breakpoint)
- FOUND: `prefers-reduced-motion` in `ScreensaverRing.vue` (exactly 1)
- CONFIRMED: `burst-ring` count in `SendBitcoinModal.vue` == 0; `success-ring` in `WalletScanModal.vue` == 0
- CONFIRMED: `npx vitest run` — 102 files, 822 tests, all pass
- CONFIRMED: `npm run build` exits 0 and `grep -rq 'viz-ring-badge' web/dist/neode-ui/assets/` succeeds

Purpose: FED-05, whose scope is LOCKED in CONTEXT.md — the "public/other" list in the channel-open
picker is *meshed peer nodes that have Lightning installed*, not `lnd listpeers`, not a curated
directory, not a live LN-graph query. That requires peers to advertise a Lightning capability plus
their URI over the mesh. RESEARCH.md Pitfall 5 confirms neither datum exists today: `handle_lnd_getinfo`
fetches LND's `/v1/getinfo` but its response struct does not deserialize `identity_pubkey` or `uris`,
and PATTERNS.md records that mesh peer capability advertisement has **no analog** in the codebase —
it is genuinely new surface, to be built on the existing typed-envelope pattern.
Output: an extended `lnd.getinfo`, a new `LightningInfo` typed mesh message, a `lightning_uri` field
on `MeshPeer`, and two new RPCs (`mesh.lightning-peers`, `mesh.send-lightning-info`).

`LndGetInfoResponse` deserialize struct (which currently declares only `alias`,
`num_active_channels`, `num_peers`, `synced_to_chain`, `block_height`), and how
`handle_lnd_getinfo` maps one into the other with `unwrap_or_default()`.
- `core/archipelago/src/api/rpc/lnd/channels.rs` around `handle_lnd_openchannel` (from L238) —
the sibling handler's pubkey validation (66 hex chars) and error-shaping style to mirror.
</read_first>
<behavior>
- Deserializing an LND `/v1/getinfo` body that contains `identity_pubkey` and a non-empty `uris`
array yields both on the mapped response.
- Deserializing a body with neither field present succeeds and yields `identity_pubkey: None`
and an empty `uris` vector — never a fabricated or placeholder identity.
- A body whose `identity_pubkey` is not 66 hex characters yields `identity_pubkey: None` rather
than propagating a malformed key that `lnd.openchannel` would later reject.
</behavior>
<action>
Write the tests first, in a `#[cfg(test)] mod tests` block in `info.rs`, driving a
`serde_json::from_str::<LndGetInfoResponse>(...)` over three fixture bodies (full, empty,
malformed pubkey) plus the mapping function. Extract the `LndGetInfoResponse` → `LndInfo`
identity mapping into a small pure function so it is testable without an HTTP call; keep the
existing HTTP flow otherwise untouched.
Add `identity_pubkey: Option<String>` and `uris: Vec<String>` to `LndGetInfoResponse` with
`#[serde(default)]`, and the corresponding `identity_pubkey: Option<String>` and
`uris: Vec<String>` to the serialized `LndInfo`. Validate the pubkey shape the same way
`handle_lnd_openchannel` does (66 hexadecimal characters) before forwarding it; on failure
forward `None`, and log at `warn!` naming the field.
Do not change any existing `LndInfo` field name or type — `HomeWalletCard.vue`, `Server.vue`,
and `Web5Wallet.vue` all read this response.

every message on the wire — this matters on LoRa).

<action>
Add `LightningInfo = 26` to `MeshMessageType` with a doc comment stating what it advertises and
that it is only ever sent on an explicit operator action. Register it in `from_u8` (26),
`from_label` ("lightning_info"), and `label`.
Add `LightningInfoPayload` next to the other payload structs: a required `uri: String` (the
`pubkey@host:port` form) and an optional `alias: Option<String>` with `#[serde(default)]`.
Follow the surrounding payload structs' serde conventions.
Add `#[serde(default)] pub lightning_uri: Option<String>` to `MeshPeer`, with a doc comment
saying it is set only from a received `LightningInfo` advertisement (or federation seeding in a
later plan) and is what the channel-open picker offers as a request target.
Add an inbound arm in `dispatch.rs` for the new type, mirroring the shape of the `Reaction` and
`Presence` arms: deserialize the payload, validate the URI before storing (a `pubkey@host` form
whose pubkey part is 66 hex characters; the `:port` suffix is optional), and on success write it
onto the resolved `MeshPeer`. On a malformed URI, log at `warn!` and return without touching a
previously stored value. Store the newest advertisement when a peer advertises more than once —
overwrite, do not accumulate.
Add unit tests in `message_types.rs` covering the round-trip of the new discriminant through
`from_u8`/`from_label`/`label`, and a `dispatch.rs`-level test (or a pure helper test if
`dispatch.rs` has no test harness) asserting that a malformed URI leaves a previously stored good
URI intact.

</read_first>
<action>
Add `handle_mesh_lightning_peers`: read the mesh peer map, keep only peers whose `lightning_uri`
is set, collapse duplicates by the peer's authenticating key (the `MeshPeer` accessor that
prefers the verified archipelago identity key over the firmware routing key) keeping the most
recently heard entry, and return a stable-sorted array — sort by display name, then by contact
id as the tiebreak, so the picker list does not reshuffle between reads. Each entry carries at
minimum: contact id, display name, `lightning_uri`, `last_heard`, `reachable`, and `hops`.
Returning zero matching peers is an empty array with a success result, never an error.
Add `handle_mesh_send_lightning_info`: take a target peer identifier in params, read this node's
own URI from the `lnd.getinfo` path built in Task 1, refuse with a clear error when no URI is
available (LND down, or no advertised URI) rather than sending an empty advertisement, then send
a `LightningInfo` envelope to that peer only. It must not broadcast to all contacts: the target
is required, and the handler returns an error when it is absent.
Register both in the dispatcher as `"mesh.lightning-peers"` and `"mesh.send-lightning-info"`,
following the existing one-line convention.
Add tests covering: empty peer map yields an empty array; two advertisements from the same peer
yield one entry with the newer URI; ordering is stable across two consecutive calls over the
same peer set; `handle_mesh_send_lightning_info` with no target errors.

## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| radio peer → typed-envelope decode → `MeshPeer` | Untrusted, unauthenticated-by-default RF input mutates local peer state |
| LND REST (`/v1/getinfo`) → daemon | Local service response parsed into an RPC payload the UI displays and copies |
| operator RPC → outbound mesh send | An operator action that discloses this node's payment endpoint to a chosen peer |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-11 | Spoofing | a radio peer advertising someone else's Lightning URI to redirect a channel open | high | mitigate | The advertisement is stored against the peer's authenticating key (the verified archipelago identity key, never the firmware routing key — see `MeshPeer`'s auth-key accessor doc); the UI in plan 01-06 labels these peers as *request* targets, not trusted opens |
| T-01-12 | Tampering | a malformed or oversized URI corrupting stored peer state | high | mitigate | URI shape validated before store (66-hex pubkey part); invalid input leaves any previously stored value untouched; test asserts this |
| T-01-13 | Information Disclosure | this node's payment endpoint leaking to every radio contact in range | high | mitigate | `mesh.send-lightning-info` requires an explicit target and errors without one; there is no broadcast path, and a received URI is never re-advertised onward |
| T-01-14 | Denial of Service | advertisement flooding growing the peer map unboundedly | medium | accept | The advertisement writes a field on an existing peer record rather than creating records; peer-map growth is governed by the pre-existing contact-discovery limits, unchanged here |
| T-01-15 | Elevation of Privilege | a new RPC becoming peer-reachable and letting a remote peer enumerate Lightning peers | high | mitigate | Both RPCs ride the existing `/rpc/v1` operator surface; the acceptance criteria assert `is_peer_allowed_path` is not widened |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | No new crates are introduced. If one becomes necessary, stop and run the Package Legitimacy Gate before installing |

- "A successful sync clears a previously recorded sync error for that peer — the badge does not persist after the peer recovers (FED-02 adjacency edge)"
- "A periodic sync pass over zero federated nodes is a clean no-op: no error is recorded, nothing is written, and no error surfaces in the UI (FED-02 empty edge)"
- "A state snapshot older than the one already stored for a peer does not overwrite the newer one — out-of-order sync responses cannot move a peer's status backwards (FED-02 ordering edge)"

- "Duplicate node entries do not accumulate across sync cycles — after sync settles the node list has one entry per federated node"

<objective>
Make federation sync converge and stop failing silently: one sync loop instead of two, a per-peer
sync error persisted and shown to the operator, and out-of-order snapshots unable to move a peer's
state backwards.
Purpose: FED-02. RESEARCH.md's anti-pattern list is explicit — both periodic sync loops in
`server.rs` log failures at `debug!` only, so a peer that has not synced in days looks identical to
one that synced a minute ago. The same section notes the two loops (90s at ~L497, 1800s at ~L840)
are redundant apart from one tail call, and that the redundancy doubles the write-race exposure that
plan 01-01 just locked down. Open Question 1 asks the reviewer to `git log -p` both loop-insertion
commits before deleting either — that check is a required step here, not an optional one.
Output: `last_sync_error` plumbed store → loop → RPC → UI badge, one surviving loop, and a
monotonicity guard on `update_node_state`.

- `core/archipelago/src/federation/types.rs` lines 50-146 — `FederatedNode`'s existing optional
fields and the doc-comment convention on `last_transport` / `last_transport_at` (a result
field written back after each attempt). The new pair mirrors that shape for the failure side.
- `core/archipelago/src/federation/storage.rs` as left by plan 01-01 — `record_peer_transport`
(the existing "write a result field back after an attempt" function) and the
`FEDERATION_STORE_LOCK` wrapper + `*_inner` split convention the new function must follow.
- `core/archipelago/src/api/rpc/federation/handlers.rs` `handle_federation_list_nodes`
(from L220) — the `serde_json::json!` node object and the `if let Some(...)` conditional-field
pattern the new fields must follow.
- `core/archipelago/src/server.rs` lines 497-600 — the 90s periodic federation sync loop, its
per-peer `sync_with_peer` call and the `debug!(peer = %node.did, error = %e, ...)` arm that
currently swallows failures.
- `neode-ui/src/views/federation/types.ts` lines 19-33 — the `FederatedNode` TS interface.
- `neode-ui/src/views/federation/NodeList.vue` lines 40-140 — the trusted-node and peer rows,
`transportBadge()` (L166) and `trustBadgeClass()` for the badge idiom to mirror, and the
existing loading row.
- `neode-ui/src/views/federation/__tests__/NodeList.test.ts` — the existing suite's mount
conventions.
</read_first>
<behavior>
- `record_sync_result(data_dir, did, Err("..."))` sets `last_sync_error` to the message and
`last_sync_error_at` to an RFC 3339 timestamp on that node only.
- `record_sync_result(data_dir, did, Ok(()))` clears both fields on that node.
- `record_sync_result` for a DID that is not in the node list is a no-op returning Ok — a peer
removed mid-pass must not be resurrected by an error write.
- `federation.list-nodes` emits both fields when set and omits them when unset.
- NodeList renders a sync-error badge on a node whose `last_sync_error` is set, and renders no
such badge when it is unset.
</behavior>
<action>
Write the Rust tests and the NodeList component test first and confirm they fail.
Add `#[serde(default)] pub last_sync_error: Option<String>` and
`#[serde(default)] pub last_sync_error_at: Option<String>` to `FederatedNode`, with a doc comment
modelled on `last_transport`: these record the outcome of the most recent sync attempt so the
operator can tell a stale peer from a healthy one, replacing a debug-only log line. Update the
`make_node` test helper in `storage.rs`'s test module so the struct literal still compiles.
Add `record_sync_result(data_dir: &Path, did: &str, outcome: Result<(), String>) -> Result<()>`
to `storage.rs`, acquiring `FEDERATION_STORE_LOCK` and using the `*_inner` load/save functions
established in 01-01. Missing DID is a silent Ok. Never create a node entry.
In `server.rs`'s 90s loop, replace the debug-only failure arm with a call to `record_sync_result`
carrying the error's display string, and call it with a success outcome on the success arm.
Truncate the recorded message to a bounded length (256 characters) so a pathological error
cannot bloat the node file. Keep the existing `debug!` line as well — persisting is additive,
not a replacement for logs.
In `handle_federation_list_nodes`, emit the two fields onto the node object using the same
`if let Some(...)` conditional-insert pattern the existing optional fields use. Add the matching
optional fields to the TS `FederatedNode` interface.
In `NodeList.vue`, add a badge on the node row shown only when `last_sync_error` is set: red
family (`alert-error`-adjacent classes already in the house style), short label, and the full
message plus the timestamp in the element's `title` attribute — the row must stay single-line, so
apply the same `truncate` + `:title` treatment the node-name span already uses. Place it beside
the existing transport badge, not in place of it. Do not add a new nav entry, card, or view —
only this badge inside the existing row.

First run the two `git log -p -L` commands above and write the answer to Open Question 1 into the
SUMMARY: does the 1800s loop do anything the 90s loop does not, beyond
`refresh_federation_mesh_peers()`? If the history shows a documented reason to keep it, STOP,
do not delete it, and record that as a finding for the FED-03 review instead — the phase then
keeps two loops and this task's remaining work is limited to routing both through
`record_sync_result`.
Otherwise: move the `refresh_federation_mesh_peers()` call to the tail of the 90s loop's
completed pass (after the per-peer iteration, alongside the existing pass-complete log), thread
whatever handle it needs into that task's captured state, and delete the entire 1800s
`tokio::spawn` block. Keep the 90s loop's startup settle delay and its asymmetry self-heal
unchanged.
Make the surviving loop's zero-node case an explicit clean no-op: when `load_nodes` returns an
empty list the pass continues to the next tick without writing anything and without recording a
sync error against anyone.

Add a monotonicity guard to `update_node_state`: parse the incoming snapshot's timestamp and the
stored `last_state`'s timestamp with `chrono::DateTime::parse_from_rfc3339`; if the incoming one
is strictly older, return Ok without mutating the node — a slow sync response that lands after a
newer one must not move the peer's status backwards. When either timestamp fails to parse, fall
back to the current accept-newest behavior so a peer with a malformed clock is not frozen out,
and log at `debug!`. Learning a peer's `fips_npub` is exempt: a stale snapshot may still carry
the only copy of a FIPS key this node has, so apply that one field even on a rejected snapshot,
and say so in a comment.
Add tests: a strictly-older snapshot leaves `last_state` and `last_seen` unchanged; an equal
timestamp is accepted (idempotent re-sync); a newer snapshot is accepted; a stale snapshot
carrying a `fips_npub` this node lacks still populates it; an unparseable timestamp is accepted.
Add a convergence test asserting that repeatedly applying the same peer's snapshot plus a
transitive-peer merge does not grow the node list — one entry per federated node after N cycles.

<objective>
Carry a federated peer's Lightning URI over the federation sync payload, so the channel-open picker
can list **trusted nodes by hostname** and open a channel with one click.
Purpose: FED-05's primary list. RESEARCH.md Pitfall 5 is blunt: building the picker before the
backend can supply a federated peer's Lightning pubkey/host produces a UI that lists names and has
nothing to pass to `lnd.openchannel`. `NodeStateSnapshot` — the payload `federation.get-state` and
sync exchange — carries no Lightning fields at all today.
Output: the sync payload extended, the peer's URI persisted and emitted by `federation.list-nodes`,
and the sharing default explicitly chosen by the operator rather than assumed.

<name>Task 1: Decide the Lightning field shape and sharing default on the federation sync payload</name>
<decision>What shape does the Lightning identity take on the federation sync payload, and is sharing on by default or opt-in?</decision>
<context>
This writes a new field into `NodeStateSnapshot`, the payload every federated node exchanges on
every sync. Once a release carrying it reaches the fleet, deployed peers parse that shape — a
later change to the field name, the split, or the sharing scope needs a coordinated fleet
upgrade plus a cleanup of URIs already cached in every peer's `nodes.json`. That is a one-way
door, and the sources disagree about which way to walk through it:
- `01-CONTEXT.md` records "a federated peer's Lightning URI rides the federation sync payload
**by default** — federation trust is already bilateral and explicit", and marks this
**Claude's discretion, revisable** — not locked.
- `01-RESEARCH.md` Open Question 3 recommends the opposite: follow the `shared_location`
precedent (opt-in, default off) "since exposing a payment channel target more broadly than
intended has real-money implications."
A second, related question rides along: `NodeStateSnapshot.federated_peers` carries a
`FederationPeerHint` for each of this node's trusted peers, used for transitive discovery. If the
Lightning field goes on the hint too, then Alice syncing with Bob learns Bob's *peers'* Lightning
URIs — a payment endpoint reaching a party that node never federated with. Options B and C below
keep the field off the hint; only choose otherwise deliberately.

opt-in field pair with its doc comment explaining absent-vs-null, and the `FederationPeerHint`

- `core/archipelago/src/api/rpc/federation/handlers.rs` around lines 470-485 — the
`shared_location` gating block (`if data.server_info.share_location { ... } else { None }`)
and how it is threaded into `federation::build_local_state`.
- `core/archipelago/src/federation/sync.rs` around lines 225-265 — `build_local_state`'s
signature and where `shared_location` is mapped into the snapshot at construction time.
- `core/archipelago/src/federation/storage.rs` `update_node_state` as left by plan 01-05,
including the monotonicity guard and the `fips_npub` exemption comment — the new field follows
the same "learn from the peer's snapshot" treatment.
- `core/archipelago/src/api/rpc/lnd/info.rs` as left by plan 01-04 — the `identity_pubkey` /
`uris` field names and the 66-hex validation helper to reuse.
- `core/archipelago/src/api/rpc/lnd/channels.rs` `handle_lnd_openchannel` (from L238) — the
exact URI/pubkey/address parsing the picker will feed, so the persisted format matches what
that handler accepts.

<behavior>
- `build_local_state` called with a Lightning URI puts it on the produced snapshot; called
without one produces a snapshot with the field absent (not an empty string).
- A snapshot deserialized from a payload that has no Lightning field succeeds with the field
`None` — an older peer syncs fine.
- `update_node_state` with a snapshot carrying a well-formed URI persists it onto the
`FederatedNode`; with a malformed URI it leaves any previously stored value untouched.
- A snapshot rejected by the plan-01-05 monotonicity guard does not clear an already-known URI.
- `federation.list-nodes` emits `lightning_uri` for a node that has one and omits it otherwise.

<action>
Implement exactly the option selected in Task 1 — do not substitute a different shape, and do not
add the field to `FederationPeerHint` unless option-a was chosen. Record the chosen option id in
the SUMMARY.
Write the tests first and confirm they fail.
Add the Lightning field(s) to `NodeStateSnapshot` with `#[serde(default)]` and a doc comment that
states the sharing rule chosen in Task 1 and explicitly notes where it differs from the
`shared_location` analog directly above it. Add `#[serde(default)] pub lightning_uri: Option<String>`
to `FederatedNode` for the locally-persisted peer value, and update the `make_node` test helper
so the struct literal still compiles.
Thread the value into `build_local_state` the same way `shared_location` is threaded: an added
parameter, mapped into the snapshot at construction. At the `handlers.rs` call site, source it
from this node's own `lnd.getinfo` identity (prefer the first entry of `uris`; fall back to
composing `identity_pubkey` with the node's reachable host when `uris` is empty), gated per the
Task 1 decision. An LND that is down or has no URI yields `None`, never an empty string and never
a fabricated address.
In `update_node_state`, learn the peer's URI from the snapshot: validate the shape before storing
(the pubkey part is 66 hexadecimal characters; the `@host[:port]` remainder is optional, matching
what `handle_lnd_openchannel` accepts), and on a malformed value log at `debug!` and leave the
prior value alone.
In `handle_federation_list_nodes`, emit `lightning_uri` with the same `if let Some(...)`
conditional-insert pattern the other optional fields use.

read and set it following the `server.set-location` shape, and make `build_local_state`'s
Lightning parameter `None` whenever the flag is off. Add tests: flag off produces a snapshot with
no Lightning field even when LND has one; flag on produces it; toggling the flag off then
re-syncing produces a snapshot without it.
Under option-a or option-b: add a read-only surface reporting the current sharing state and the
URI actually being shared, so the operator can see what is going out; and make the outbound value
`None` whenever this node's own Lightning is not installed or not reachable. Add tests: no LND
produces no Lightning field; a present LND produces the URI; the reported state matches what
`build_local_state` actually emits.
In both cases, add a test asserting a third-party peer's Lightning URI is never re-exported in
this node's own outbound peer hints — build a local state while holding a peer whose URI is
known, serialize it, and assert that URI string does not appear in the outbound payload's peer

<objective>
Give a meshed Lightning peer a way to be *asked* for a channel: a typed mesh message carrying the
requester's Lightning URI and an optional note, sent to one chosen peer and rendered in the
recipient's conversation.
Purpose: FED-05's second list. CONTEXT.md locks the semantics — meshed peers with Lightning
installed are nodes you "request to open a channel with", not nodes you open against directly,
because mesh peers are not bilaterally trusted the way federated nodes are. 01-UI-SPEC.md fixes the
UI verb ("Request Channel", reusing `PeerRequestModal.vue`'s message field and busy states).
PATTERNS.md records that the send/receive shape for this is `typed_messages.rs`'s existing
reaction/reply family — a struct-per-message-type serialized into the standard envelope — and that
no capability/request mechanism exists yet to extend.
Output: `MeshMessageType::ChannelOpenRequest`, its payload, an inbound arm that stores it as a
conversation message, and a `mesh.request-channel` RPC.

- `core/archipelago/src/mesh/message_types.rs` — the enum and the four places every variant is
registered (`enum`, `from_u8`, `from_label`, `label`), `InvoicePayload` (from L413) as the
closest payload analog (it also carries a payment-ish string plus an optional amount), and the
`TypedEnvelope` doc comment on `compact_bytes` and LoRa frame size.
- `core/archipelago/src/api/rpc/mesh/typed_messages.rs` lines 637-760 — `handle_mesh_send_reply`
and `handle_mesh_send_reaction`: param extraction, target-peer resolution, sequence-number
allocation, `TypedEnvelope::new(...).with_seq(seq)`, and the send call.
- `core/archipelago/src/mesh/listener/dispatch.rs` lines 430-500 — the `Reaction` and `Presence`
inbound arms, and how an inbound typed message is turned into a stored `MeshMessage` with
`message_type` and `typed_payload` set.
- `core/archipelago/src/mesh/types.rs` lines 139-180 — the `MeshMessage` fields the stored
request must populate (`plaintext` is the human-readable fallback shown in list views).
- `core/archipelago/src/api/rpc/dispatcher.rs` lines 390-440 — the one-line registration convention.
- `.planning/phases/01-federation-mesh-hardening/01-UI-SPEC.md` — the Copywriting Contract row
for "Primary CTA — meshed Lightning peer", which fixes what the UI in plan 01-08 will send.
</read_first>
<behavior>
- `MeshMessageType` round-trips the new variant through `from_u8`, `from_label`, and `label`.
- `handle_mesh_request_channel` with no target peer in params returns an error; with an unknown
target peer it returns an error naming the peer.
- `handle_mesh_request_channel` with a target sends exactly one envelope of the new type, whose
payload carries this node's own Lightning URI and the caller's optional amount and message.
- Two consecutive calls to the same target allocate two different sequence numbers.
- An inbound envelope of the new type with a well-formed URI is stored as a `MeshMessage` whose
`message_type` is the new label and whose `typed_payload` carries the request fields.
- An inbound envelope whose payload URI is malformed stores nothing and logs a warning.
</behavior>
<action>
Write the tests first and confirm they fail.
Add `ChannelOpenRequest = 27` to `MeshMessageType` (confirm 27 is unused first) with a doc comment
stating that this is a *request*, that it carries no channel state, and that receiving one never
causes the node to act. Register it in `from_u8`, `from_label` ("channel_open_request"), and
`label`.
Add `ChannelOpenRequestPayload` beside the other payload structs: a required `uri: String` (the
requester's own `pubkey@host:port`), plus `#[serde(default)] amount_sats: Option<u64>` and
`#[serde(default)] message: Option<String>`. Bound the optional message length before send so a
long note cannot blow past the LoRa framing budget the `TypedEnvelope` doc comment warns about;
truncate at the send side rather than rejecting, and say so in a comment.
Add `handle_mesh_request_channel` following the `handle_mesh_send_reply` shape: require a target
peer identifier in params and error without one (there is no broadcast form); read this node's
own Lightning URI via the identity path plan 01-04 added to `lnd.getinfo`, and error with a clear
message when it is unavailable rather than sending an empty request; build the payload, wrap it in
a `TypedEnvelope` with a freshly allocated sequence number, and send it to that peer only.
Register it in the dispatcher as `"mesh.request-channel"`.
Add the inbound arm in `dispatch.rs` mirroring the `Reaction` arm: deserialize the payload,
validate the URI shape (66-hex pubkey part, optional `@host[:port]`), and on success store a
`MeshMessage` with the new label as `message_type`, the payload as `typed_payload`, and a
human-readable `plaintext` summary naming the requester and the requested amount when present.
On a malformed URI, log at `warn!` and store nothing.
Do not add any code path that connects to, opens a channel with, or funds the requester on
receipt. The inbound arm's only effect is storing a message.

<action>
Add a short duplicate-suppression window to `handle_mesh_request_channel`: a second request to the
same target peer within a bounded interval returns a distinct, non-error result reporting that a
request was already sent, rather than emitting a second envelope. The UI in plan 01-08 also
disables its button while a send is in flight, but a backend guard is what actually stops a
double-click or a retried RPC from spamming a peer over a slow radio link. Two requests separated
by more than the window must both go out — the window suppresses accidental duplicates, not
legitimate repeat requests. Add tests for both sides of the window.
Bound the inbound side too: reject an inbound payload whose message field exceeds the same
length bound the send side truncates at, and reject an `amount_sats` outside the range
`handle_lnd_openchannel` accepts (its existing 20,000..=16,777,215 sat bounds) so a request can
never carry an amount the recipient could not act on. Read `channels.rs` for those exact bounds
rather than restating them from memory.
Attribute the stored inbound message to the peer's authenticating identity key, not the firmware
routing key, following the `MeshPeer` accessor's documented rule — a request that claims to be
from a trusted peer must be attributable.

|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-26 | Spoofing | a peer sending a request that appears to come from a trusted node, luring a channel open to an attacker's URI | high | mitigate | The stored message is attributed to the peer's verified archipelago identity key, never the firmware routing key (Task 2); the recipient's action on a request is always explicit and human |
| T-01-27 | Elevation of Privilege | a received request causing an automatic channel open or fund movement | high | mitigate | The inbound arm's only effect is storing a message; the acceptance criteria require reading the arm and recording that it contains no open/connect/send-funds call |
| T-01-28 | Denial of Service | request flooding filling a peer's conversation or saturating a LoRa link | high | mitigate | Send-side duplicate-suppression window plus inbound length and amount bounds (Task 2) |
| T-01-29 | Information Disclosure | broadcasting this node's payment endpoint to every contact in range | high | mitigate | A target peer is required; the handler errors without one and there is no broadcast form |
| T-01-30 | Tampering | an oversize payload fragmenting into unreassemblable LoRa chunks | medium | mitigate | The message field is truncated at the send side against the framing budget the `TypedEnvelope` doc comment describes; inbound oversize is rejected |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | No new crates. If one becomes necessary, stop and run the Package Legitimacy Gate before installing |

<objective>
Make channel opening between nodes first-class UI: share your node's Lightning URI, open a channel
with a trusted federated node in one click, and request a channel from a meshed peer that has
Lightning installed.
Purpose: FED-05's user-facing half, with scope locked in CONTEXT.md (the second list is *meshed peer
nodes that have Lightning installed* — not `lnd listpeers`, not a curated directory, not a live
LN-graph query) and its visuals fixed by 01-UI-SPEC.md (copy, colours, spacing, the shared empty
state, the de-emphasised manual-paste fallback, and the hard modal rule).
Output: a new picker modal built from the house design system, reached from the Lightning panel's
existing Open Channel button, working against the demo and against archi-dev.

- `neode-ui/src/components/BaseModal.vue` — the whole file. It already wraps `Teleport to="body"`,
the full-screen `bg-black/60 backdrop-blur-md` backdrop, `@click.self` close, the pinned
`text-xl font-semibold` title, and the scrolling body. The new modal MUST use it; never nest a
modal inside a transform-affected ancestor.
- `neode-ui/src/components/LightningChannelsPanel.vue` lines 246-360 (its current bespoke
open-channel modal, its `openError` ref, `isStartupNotice()` amber-vs-red distinction, and the
fee-preset block) and lines 505-630 (`showOpenModal`, `defaultOpenForm()`, `openForm`,
`openingChannel`, and the validate-before-RPC sequence including the 20,000-sat minimum and the
`pubkey@host:port` split with an optional address).
- `neode-ui/src/views/federation/NodeList.vue` lines 40-140 and 155-190 — the row layout to
mirror (truncated name with `:title`, transport badge, trust badge, action button), the
`trustedNodes` / `peerNodes` computed filters, and the "Loading nodes..." row.
- `neode-ui/src/api/rpc-client.ts` lines 795-850 — the one-line
`this.call({ method: '<ns>.<verb>', params })` wrapper convention and the existing
`federation.list-nodes` wrapper.
- `neode-ui/mock-backend.js` — the `lnd.getinfo`, `lnd.openchannel`, and `federation.list-nodes`
cases, and the parity harness added by plan 01-02.
- `.planning/phases/01-federation-mesh-hardening/01-UI-SPEC.md` — Design System, Spacing,
Typography, Color, and the full Copywriting Contract. Every string in this modal comes from
that table verbatim.
</read_first>
<behavior>
- Mounted with a node list containing one trusted node that has a Lightning URI and one that does
not, the trusted list renders exactly one row.
- The row shows the node name (truncated, with a `title`), its trust badge, its transport badge,
and an Open Channel button.
- Clicking Open Channel calls the open RPC once with that node's URI; clicking it twice in
immediate succession still results in exactly one call, and the button is disabled while in
flight.
- While the node list is loading, the loading treatment renders and no empty state renders.
- When the node fetch rejects, the error row renders with the contract's error copy.
- The modal root renders through the house modal shell, so the backdrop is a full-screen sibling
of the card rather than a child of a transformed ancestor.
</behavior>
<action>
Write the test file first and confirm it fails.
Add rpc-client wrappers for `mesh.lightning-peers`, `mesh.send-lightning-info`, and
`mesh.request-channel` following the existing one-line convention. Extend the mock backend so the
demo answers all three, so `lnd.getinfo` returns an `identity_pubkey` and a `uris` array, and so
`federation.list-nodes` nodes carry `lightning_uri` — mirroring the real handlers per the mock's
established "cite the daemon source" comment convention. The plan-01-02 parity harness must stay
green.
Create `LightningChannelModal.vue` using `BaseModal` as its shell, title "Open Lightning Channel".
In this task implement the trusted-node section only: fetch the federated node list, keep nodes
whose trust level is trusted AND which have a Lightning URI, sort by display name with a stable
tiebreak so the order does not shuffle between refreshes, and render each as a row mirroring the
federation node row — truncated name with a `title` tooltip, the transport badge reusing
NodeList's existing FIPS/Tor logic, the trust badge, and an Open Channel button on the right.
Wire Open Channel to the existing open-channel RPC, reusing the panel's proven sequence: validate
before calling, keep the 20,000-sat minimum, split the URI into pubkey and optional address, and
reuse the `openError` ref plus the `isStartupNotice()` amber-vs-red distinction rather than
inventing a new error idiom. Guard against double submission with an in-flight flag keyed to the
target so the button is disabled and a second click is a no-op.
Point the Lightning panel's **existing** Open Channel button at this modal instead of its bespoke
one. Do not add a new nav entry, route, card, or dashboard tile — the user places new entry
points, this plan only upgrades the one that already exists. Leave the panel's channel list,
close-channel flow, and fee presets untouched.
Follow the UI-SPEC tables exactly: spacing on the 4px grid, the two-weight typography scale,
accent orange reserved for the primary action buttons, the bolt icon path already used elsewhere
in the app, and the copy strings verbatim.

building a second request modal.

- The plan-01-07 SUMMARY — the exact params `mesh.request-channel` expects.
</read_first>
<action>
Add the meshed-Lightning-peers section below the trusted list: fetch via `mesh.lightning-peers`,
render rows in the same layout with a Request Channel button in place of Open Channel, and sort
with the same stable ordering rule.
Deduplicate across the two lists: a peer that is both a trusted federated node and a meshed
Lightning peer appears only in the trusted list. Match on the identity available in both payloads
(the node's Lightning URI is the reliable common key; fall back to the peer's archipelago identity
key when present). Never match on display name.
Wire Request Channel to `PeerRequestModal` — mount it with the optional message field, and on its
send event call `mesh.request-channel` with the target peer and the message. While a request is
in flight the row's button is disabled and shows the busy label; a second click is a no-op. On
success show a sent-request confirmation on the row. That confirmation must not claim a channel
exists, is pending funding, or is connected; it says a request was sent and nothing more.
Add the shared empty state: when the trusted list and the meshed list are BOTH empty, render the
UI-SPEC's empty heading and body exactly once for the pair — not once per list. When only one is
empty, that section renders nothing rather than its own empty state. Render the house loading
treatment per section while its fetch is in flight, and the contract's error row on a failed
fetch, using the same `openError` / startup-notice idiom as Task 1.
Extend the mock backend so `mesh.lightning-peers` returns a small demo peer set and
`mesh.request-channel` records the request in the session store so the demo shows the same sent
state a real node does.
Extend the test suite: both-empty renders one empty state; one-empty renders none for that
section; a peer present in both lists renders once and in the trusted list; ordering is identical
across two consecutive renders of a shuffled input; a double click on Request Channel produces one
call; the sent confirmation contains no open or connected wording.

copy-feedback idiom.
- `neode-ui/src/components/LightningChannelsPanel.vue` lines 250-270 and 595-625 — the
`pubkey@host:port` placeholder, the `Format: pubkey@host:port` helper text, and the
validate-before-RPC sequence including the address-optional split.
- `.planning/phases/01-federation-mesh-hardening/01-UI-SPEC.md` — the Copywriting Contract rows
for "Primary CTA — own URI" and "Manual fallback entry point", and the UI Considerations rows
marked backstop for the manual-paste form.
</read_first>
<action>
Add the own-node URI block at the top of the modal: read this node's Lightning identity from
`lnd.getinfo`, display the URI truncated to its container with the full value in a `title`
tooltip, and add a copy button whose label flips to the confirmation string for about two seconds.
The clipboard receives the full untruncated value regardless of visual truncation. When the node
has no Lightning URI available, the block explains that instead of showing an empty field or a
fabricated address.
Add the manual-paste fallback below both lists as a de-emphasised disclosure, not a third
equal-weight column: the entry point reveals a peer URI input with the placeholder and helper text
reused verbatim from the Lightning panel. Validate client-side before calling the open RPC — a
value that is not in `pubkey@host:port` form is rejected with the format message and no RPC is
issued; a bare pubkey with no host is accepted and passes an undefined address through, which is
the behavior the open RPC already supports. Reuse the same error ref and startup-notice treatment.
Extend the test suite: the copy button places the full untruncated URI on the clipboard and its
label flips then reverts; the URI element carries a `title` with the full value; an invalid
pasted value shows the format message and issues no RPC call; a bare pubkey issues the open call
with an undefined address; the no-URI-available state renders its explanation rather than an
empty field.
Then verify on the dev preview against archi-dev before this plan is considered complete, per the
user requirement in CONTEXT.md: the preview at the dev port, the copy button, the trusted list,
the meshed list, the request flow, and the manual paste. Record what was exercised in the SUMMARY.
The blocking human sign-off is consolidated into plan 01-09.

| T-01-32 | Tampering | a peer-supplied node name or URI containing markup that renders as UI | high | mitigate | Vue's default text interpolation escapes; the plan uses no `v-html` anywhere. A test asserting a name containing angle brackets renders as text is required before this row can be dispositioned |
| T-01-33 | Repudiation | a sent request being read as an open channel, so a user believes they have inbound liquidity they do not | high | mitigate | The sent confirmation is worded as a request only; a test asserts the confirmation contains no open or connected wording |
| T-01-34 | Denial of Service | a double click or a fast repeat committing two channel opens to the same peer | high | mitigate | An in-flight flag keyed to the target disables the action and makes a second click a no-op, backed by the plan-01-07 backend suppression window; a test asserts exactly one call for two immediate clicks |
| T-01-35 | Information Disclosure | this node's Lightning URI being displayed to a shoulder-surfer or copied in a shared session | low | accept | A Lightning URI is a public payment endpoint by design; it is deliberately shareable and carries no spend authority |
| T-01-36 | Elevation of Privilege | the modal bypassing the open RPC's server-side validation by calling with unvalidated input | medium | mitigate | Client-side validation is additive only; the existing server-side pubkey-format and amount-bounds validation in the open handler is reused unchanged and is the authority |

<objective>
Run the structured code review FED-03 requires over the federation/fleet area and the mesh area, and
close it out: every finding fixed or explicitly deferred with a reason.
Purpose: FED-03. RESEARCH.md Pitfall 2 is the governing constraint — `.planning/codebase/CONCERNS.md`
is NOT current truth for this phase. At least two of its federation claims were already fixed on main
before this phase started (the tombstone-write-swallowed claim was fixed in `01cbec27`; the
peer-joined DID path does verify an ed25519 signature). Re-fixing an already-fixed bug wastes the
review and risks reverting working code, so every claim gets a fresh code read plus a git-history
check before it is filed or dismissed.
Output: `01-REVIEW-FINDINGS.md` with a disposition on every finding, the small findings fixed inline,
and the phase's code deployed to the dev pair so plan 01-10's verification has something to test.

Create `01-REVIEW-FINDINGS.md` with a table whose columns are: finding id (`F-01`, `F-02`, …),
area (federation store / federation sync / federation RPC / FIPS-transport dial / mesh core /
mesh RPC surface), severity, the file and line citation, the evidence (what was read and what
`git log -p` or `git blame` showed), the disposition (`fixed` / `already-fixed` / `deferred`), and
for `fixed` the commit plus the verifying command or test name, or for `deferred` the reason and
the owning phase or requirement.
Then take exactly one finding all the way through in this task, to prove the pipeline: re-verify
the codebase-concerns claim about incomplete federation DID validation — specifically the part
RESEARCH.md flags as un-re-verified, whether anything checks proof of ownership of a DID on first
contact, as opposed to the peer-joined path which does verify a signature. Read the add-node and
peer-joined paths in the federation RPC handlers and run `git log -p` on them. File the finding
with its evidence, then either fix it (if the fix is contained and does not touch federation trust
or join cryptography beyond what correctness requires — CONTEXT.md's scope fence) or defer it with
a written reason naming what a fix would touch and why that belongs elsewhere.
Record the two claims RESEARCH.md already verified as fixed with their commits, as `already-fixed`
rows, so a future reader does not re-open them.

Review each area in turn and add its findings to the document. For each codebase-concerns claim,
do the fresh read plus `git log -p` on the cited range BEFORE filing or dismissing it, and put
that evidence in the row — a finding that merely restates a concerns bullet without fresh
evidence is not admissible.
Areas to cover, each of which must appear in the document even when it produced no findings —
record those as reviewed with none rather than omitting them: federation store, federation sync,
federation RPC surface, FIPS and transport dial, mesh core, mesh RPC surface.
Required specific checks, each of which becomes a row:
- The mock-parity residual class flagged in the plan 01-02 SUMMARY (a mock case that exists but
returns a differently-shaped success object than the daemon).
- Whether the paid-tick grep from plan 01-03 still finds exactly the two surfaces it found at
planning time, or whether a third has appeared.
- The unbounded-curl concern: confirm it belongs to the multinode test harness and defer it to
the phase that owns that requirement, with that phase named in the reason.
- The node-list dedup scaling note: disposition it with the peer counts this fleet actually runs.
- The mesh radio configuration boot race: confirm against current code and defer if it needs real
LoRa hardware, naming that as the reason.
Fix findings that are contained — a bounded change inside the reviewed area with a test — and
commit each as its own focused commit per CLAUDE.md. Defer anything that would breach the
CONTEXT.md scope fence, require hardware this session lacks, or belong to another phase, and write
the reason and the owner in the row. Every row ends with exactly one disposition.
Finish with a short summary section stating the counts: findings filed, fixed, already-fixed, and
deferred; and a line stating that the counts sum to the number of rows.

Deploy to archi-dev-box and then to x250-dev using the established deploy script, one at a time.
After each, verify the deployed binary's sha256 matches the locally built artifact, and record

<objective>
Consolidate every human-gated verification this phase owes into one sign-off, run against the dev
pair rather than the demo.
Purpose: `01-VALIDATION.md` lists three manual-only verifications (removal sticking across real sync
cycles, the channel-open flow end to end, and the paid-tick visual), and CONTEXT.md adds the user's
own requirement that FED-05 and FED-06 are verified on the dev preview against archi-dev **before any
deploy**. Rather than interrupting each implementation plan with its own checkpoint, they are gathered
here so the operator is asked once, after the code is on the dev pair.
Output: a recorded sign-off, or a list of issues that becomes the input to a gap-closure pass.

## Artifacts this phase produces
This plan produces no new symbols. It verifies the artifacts produced by plans 01-01 through 01-09:
the serialized federation store, the sync-error badge, the mesh Lightning identity and request
messages, the federation Lightning URI field, the channel-open picker modal, the branded paid tick,
and the demo RPC parity harness.
<tasks>
<task type="checkpoint:human-verify" gate="blocking">
<name>Task 1: Phase 1 consolidated verification on the dev pair</name>
<what-built>
Phase 1 in full, deployed to archi-dev-box and x250-dev and sha256-verified by plan 01-09:
- Federation node-store writes are serialized behind one lock with an atomic node-list write, so
a removal issued during a sync pass can no longer be undone by that sync.
- One periodic federation sync loop instead of two; per-peer sync failures are persisted and
shown as a badge on the node row, clearing when the peer recovers; out-of-order snapshots can
no longer move a peer's state backwards.
- A new channel-open picker modal reached from the Lightning panel's existing Open Channel
button: your own node's Lightning URI with a copy button, trusted federated nodes listed by
hostname with a one-click open, meshed peers running Lightning listed separately with a
request flow, and a manual URI paste fallback.
- The payment-success tick now uses the screensaver ring with its EQ segments on both the send
modal and the scan modal.
- The demo backend answers every mesh and federation RPC the UI calls, and reactions, edits,
deletes, and peer aliasing change demo state instead of returning a bare acknowledgement.
</what-built>
<how-to-verify>
Run these against the dev pair, not the demo, except where a step says demo.
1. **Removal sticks (FED-01).** On archi-dev-box, open the Federation view and remove a federated
peer. Wait through at least two auto-sync cycles — the loop runs every 90 seconds, so give it
four minutes — then reload. Expected: the peer is gone and stays gone. Then try removing a peer
that no longer exists (repeat the removal): expected an error message, not a silent success.
2. **Sync errors are visible (FED-02).** Make one federated peer unreachable — take its node off
the network, or block it — and wait one sync cycle. Expected: that node's row shows a sync-error
badge, and hovering it shows the error text and when it happened. Bring the peer back and wait
one more cycle. Expected: the badge clears on its own.
3. **Channel opening (FED-05).** Open the dev preview pointed at archi-dev and go to the Lightning
channels panel, then click Open Channel. Expected: a full-screen modal (the backdrop covers the
whole window and clicking outside closes it), showing your node's Lightning URI at the top.
Click Copy Lightning URI: expected the label flips to Copied! for about two seconds, and pasting
elsewhere gives the complete URI even though the on-screen text is shortened. Check the trusted
list shows your federated nodes by hostname with their FIPS or Tor badge. Check the meshed
Lightning peers list below it. Click Request Channel on a meshed peer, add a short message, and
send: expected a "request sent" style confirmation that does NOT claim a channel is open or
connected. Click Paste URI Manually, enter something malformed such as text with no at-sign:
expected a format message and no attempt to open. Then paste a valid peer URI: expected the
normal open flow. Finally, double-click Open Channel on a trusted node: expected one open
attempt, with the button disabled while it runs.
4. **Paid tick (FED-06).** On the dev preview, trigger a payment success in the send modal and in
the scan modal. Expected: the checkmark now sits inside the screensaver-style ring with the
radiating segment lines, at both a narrow phone width and a desktop width, with nothing cut off
by the edge of the card. The amount and the SENT wording are unchanged.
5. **Demo and real node match (FED-04).** On the demo, rename a mesh peer, react to a message,
edit one, delete one, and send a small file attachment. Then do the same on archi-dev.
Expected: the same modals appear in the same situations, the changes are visible in both, and
the browser console shows no "Method not found" errors on either.
6. **Single-node gate stays green (CLAUDE.md mandate).** Phase 1 modified daemon internals
(`federation/storage.rs`, `server.rs` — a periodic loop was removed), which falls under the
"re-run the gate after orchestrator/lifecycle changes" rule. Run `tests/lifecycle/run-gate.sh`
ON a dev-pair node (gate runs on-node, never via RPC). Expected: green, 0 not-ok. A full 5×
run on .228 is NOT required here (that is Phase 3's multinode criterion) — one clean pass on
the dev pair is the insurance this checkpoint needs.
If anything fails, describe what you saw and which numbered step it was — that becomes the gap
list for a closure pass rather than a re-run of the whole phase.

---
<objective>
Remove every shipped Fedimint gateway credential from the tree and make each install derive its own,
so two nodes flashed from the same ISO never answer to the same gateway password.
Purpose: FED-07 is a BLOCKER. `apps/fedimint-gateway/manifest.yml` already declares the right thing
(`generated_secrets: fedimint-gateway-hash, kind: bcrypt`), and `container::secrets` already
materialises it per install at 0600 — but five code paths bypass that and substitute a hash literal
committed to this repository when the secret is missing, and one deploy path substitutes a plaintext
password literal. Anyone with a copy of this repo holds the admin credential for every gateway that
ever took one of those fallbacks. The repo's own standing invariant already forbids this: "Secrets are
manifest-declared (`generated_secrets`, materialised by `container::secrets`, 0600/rootless) — never
hardcoded, per-app, or logged."
Output: one canonical per-install accessor, five fallback sites removed, a detection-only denylist,
and tests that fail if a credential literal is ever reintroduced.

<read_first>
- `core/archipelago/src/container/secrets.rs` — the whole file (about 225 lines). Note
`ensure_one`'s `SecretGenKind::Bcrypt` arm: it already generates a 24-byte random hex password,
bcrypt-hashes it, writes the hash to `<name>` and the plaintext to `<name>.pw`, both 0600 via
the atomic `write_secret` helper. Note the idempotent fast path and the self-heal branch. This
is the behaviour the new accessor must reuse, not reimplement.
- `core/archipelago/src/api/rpc/package/config.rs` lines 596-620 (`read_secret`, which takes a
`default: &str` — the mechanism that makes a fallback literal possible) and lines 1051-1084
(the `"fedimint-gateway"` match arm inside the app-config table, where the hash is read with a
literal default and then passed to `--bcrypt-password-hash`).
- `core/archipelago/src/api/rpc/package/dependencies.rs` lines 718-769 (`configure_fedimint_lnd`)
— the second site, reading the same secret path directly with `unwrap_or_else` onto the same
literal, then rebuilding the whole argv in LND mode.
- `core/archipelago/src/api/rpc/package/install.rs` lines 583-606 — how `get_app_config` and
`configure_fedimint_lnd` are called during install, so you can see what an error from either
has to propagate through.
- `apps/fedimint-gateway/manifest.yml` — the `generated_secrets` block already declaring
`fedimint-gateway-hash` with `kind: bcrypt`, and the `secret_env` mapping `FEDI_HASH` to it.
The manifest is already correct; this task makes the non-manifest paths agree with it.
</read_first>
<behavior>
- `ensure_gateway_credential` on an empty secrets dir writes both the hash file and its `.pw`
sibling, each 0600, and the plaintext verifies against the hash.
- Called a second time on the same dir it changes nothing — the hash read back is byte-identical.
- `gateway_bcrypt_hash` on a dir with no gateway secret returns `Err`, and the error message names
the missing secret file so an operator can act on it.
- `gateway_bcrypt_hash` on a dir whose stored hash is a known-default denylist entry returns `Err`
rather than handing the compromised value back to a caller.
- Two successive fresh generations in two different temp dirs produce two different hashes — the
value is per install, not per build.
</behavior>
<action>
Write the tests in `secrets.rs`'s existing `mod tests` first and confirm they fail.
In `core/archipelago/src/container/secrets.rs` add three items.
First, a private denylist constant `KNOWN_DEFAULT_GATEWAY_HASHES: &[&str]` holding the single
bcrypt hash currently used as a fallback at `config.rs:1054` (copy it from there verbatim). Give
it a doc comment saying it exists only so an install carrying it can be detected and rotated, that
it must never be handed to a container, and that plan 01-16 consumes it for the migration. This is
the one and only place that value may appear in the tree after this plan.
Second, `pub fn ensure_gateway_credential(secrets_dir: &Path) -> Result<()>` — a thin wrapper that
reuses the existing bcrypt generation path for the `fedimint-gateway-hash` name rather than
duplicating it. Factor the `SecretGenKind::Bcrypt` arm of `ensure_one` into a small helper both
call so there is exactly one bcrypt-generation implementation; keep `ensure_one`'s existing
idempotent fast path and self-heal semantics intact so callers on a reconcile tick never rotate a
working credential.
Third, `pub fn gateway_bcrypt_hash(secrets_dir: &Path) -> Result<String>` — reads the canonical
hash file, trims it, and returns `Err` with a message naming the file path when it is missing,
empty, or unreadable. Before returning Ok, compare the trimmed value against the denylist and
return `Err` if it matches, with a message saying the install is carrying a publicly known default
and pointing at the rotation path.
In `config.rs`: change the `"fedimint-gateway"` arm to obtain its hash from
`container::secrets::gateway_bcrypt_hash`, calling `ensure_gateway_credential` first so a fresh
node self-provisions. Because `get_app_config` returns a tuple rather than a `Result`, do not
silently swallow the error — surface it the way the surrounding code surfaces other hard install
failures (an `Err` return threaded to the caller if the signature already allows it, otherwise a
logged error plus an argv the install path rejects; whichever you choose, an install with no
credential must not reach `podman run`). Record the choice and its reason in the SUMMARY. Delete
the `default` parameter from `read_secret` if no other caller needs it; if other callers do, leave
the helper alone and simply stop routing the gateway through it.
In `dependencies.rs`: `configure_fedimint_lnd` must take the already-resolved hash as a parameter
from its caller rather than re-reading the file with its own fallback, so there is one read site
and one failure point. Update the `install.rs` call accordingly.
Do not change the gateway's ports, volumes, data directory, network, capabilities, health check,
or any non-credential argv element. This task changes where the credential comes from, nothing
else about how the gateway runs.

the hash, and on a host without `htpasswd` logs a warning and assigns the shipped literal. This
is the ISO first-boot path, so this is the site that put the default on real nodes.

770-793 (the container-creation block, where a plaintext password fallback is substituted when
the password file cannot be read, and where the argv uses a plaintext password flag rather than
the hash flag every other path uses).
- `scripts/container-specs.sh` lines 60-72 — the shared spec loader, which reads
`fedimint-gateway-hash` (correct name) and escapes `$` so the bcrypt hash survives the
`eval` in `reconcile-containers.sh`'s `build_run_cmd`. Preserve that escaping.
</read_first>
<action>
Replace the htpasswd-or-fallback pattern everywhere with generation that has no fallback.
In `first-boot-containers.sh` and `reconcile-containers.sh`: keep generating the plaintext with
`openssl rand`, but when `htpasswd` is unavailable do NOT assign a shipped value. Either compute
the bcrypt hash without `htpasswd` (openssl's `passwd` applet does not emit bcrypt, so if you go
this route use a hasher the host actually has — verify what is present on a node before choosing)
or, if no local hasher exists, leave the hash file absent and let the daemon's
`ensure_gateway_credential` from Task 1 materialise it on the next reconcile tick. The second
option is preferred: it removes the host dependency entirely and puts generation on the one
canonical path. In that case the script must log that the gateway credential will be generated by
the daemon, and must not create a half-provisioned pair of files.
Unify the naming. The manifest and the daemon use `fedimint-gateway-hash` for the hash and
`fedimint-gateway-hash.pw` for the plaintext; the scripts use `fedimint-gateway-password` for the
plaintext. Converge on the manifest's names. Where a script currently writes
`fedimint-gateway-password`, have it write the `.pw` sibling name instead, and — because
migrations never destroy data — if the legacy file exists and the new one does not, copy the value
across (preserving 0600) rather than regenerating, so a node that already has a working unique
credential keeps it. Never delete the legacy file in this plan; plan 01-16 owns retirement.
In `deploy-to-target.sh` and `deploy-tailscale.sh`: when the hash read back from the target comes
back empty, abort that step with a clear message instead of substituting the literal. A deploy that
cannot read the target's credential must not create a gateway container. In
`deploy-tailscale.sh`'s container-creation block, remove the plaintext-password fallback on line
777 entirely and switch that argv to the same hash flag every other path uses, sourced from the
same secret; if the hash is unavailable, skip creating the gateway container and print why.
In `container-specs.sh`: leave the secret name as-is (it is already canonical) and leave the `$`
escaping intact; only add the empty-value guard so a missing hash produces a skipped spec with a
message rather than an empty hash argument.
Every changed script must stay `sh`-compatible where it already is and must pass `bash -n`.

- The SUMMARY records, for each of the five scripts, what the no-credential path now does, and confirms the legacy plaintext filename is copied forward rather than regenerated when present.
</acceptance_criteria>
<done>No script in the tree can configure a gateway with a credential that shipped with the repo; a node with no credential gets one generated for it or is told why the gateway was skipped.</done>
</task>
</tasks>
## Planner Assumptions (flagged, unresolved)
- **Whether the compromised hash's plaintext is publicly recoverable:** the planner did not run
`bcrypt::verify` against candidate plaintexts. The severity of FED-07 does not depend on it (a
shipped hash is a shipped credential regardless), but the migration in plan 01-16 phrases its
operator message differently if the plaintext is a guessable word. Task 1's tests are the natural
place to settle it; record the finding in the SUMMARY either way.
- **Whether `get_app_config`'s signature can return `Result` without a wide refactor:** the planner
read the call site but not every arm of the table. Task 1 explicitly allows either mechanism and
requires the choice to be recorded, so this is a bounded implementation decision, not a scope gap.

## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| repository → running node | Anything committed here reaches every node and every reader of the mirror |
| gateway admin API (`0.0.0.0:8176`) → network | The credential this plan governs is the only thing gating Lightning gateway administration |
| deploy host → target node over SSH | Credentials are read back across this boundary by two deploy scripts |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-50 | Elevation of Privilege | shipped default credential granting gateway admin on any node that took a fallback | critical | mitigate | Both tasks delete every configure-time fallback; the repo-wide grep acceptance criterion fails the task if any credential literal survives outside the detection denylist |
| T-01-51 | Spoofing | an attacker authenticating to a node's gateway with the publicly known default | critical | mitigate | `gateway_bcrypt_hash` refuses to return a denylisted value, so a node carrying it cannot be reconfigured with it even by this codebase |
| T-01-52 | Information Disclosure | the generated plaintext leaking through a log line or a deploy transcript | high | mitigate | Generation reuses `write_secret` (0600, atomic, never logged); the scripts are changed to log only that generation happened, never the value; the acceptance criteria forbid printing it |
| T-01-53 | Denial of Service | removing the fallback bricking installs on hosts without a bcrypt hasher | medium | mitigate | Task 2's preferred branch removes the host-tool dependency entirely by deferring to the daemon's own generator, and requires the skip path to print a reason rather than fail silently |
| T-01-54 | Tampering | a half-written credential pair leaving a gateway configured against a hash whose plaintext nobody holds | medium | mitigate | Generation reuses the existing atomic temp-file-plus-rename `write_secret` and its self-heal branch; Task 2 forbids creating a half-provisioned pair |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs no packages — it edits existing Rust and shell only. If an implementation choice would add a crate, stop and raise it: RESEARCH.md's Package Legitimacy Audit must cover it first, with a blocking human checkpoint for any `[ASSUMED]`/`[SUS]` entry |

Chosen over the plan's alternative (log + an argv the install path rejects) because it makes the failure unrepresentable rather than conventional — an install with no credential cannot reach `podman run` at all, and every other arm was mechanically wrapped in `Ok(...)` with no behaviour change. The one call site in install.rs became `.await?`."
- "`configure_fedimint_lnd` now takes the resolved hash as a parameter instead of re-reading the secrets file with its own fallback, so there is exactly one read site and one failure point."
- "`read_secret(name, default)` in config.rs was left intact — 6 other call sites still use its default parameter, so per the plan's explicit branch the gateway was simply routed off it rather than removing the helper."
- "Shell paths generate nothing: first-boot, reconcile and both deploys defer bcrypt generation to the daemon. This removes the htpasswd host dependency entirely (the plan's preferred branch) and keeps bcrypt generation in exactly one implementation."
- "deploy-tailscale.sh's gateway argv was switched from the plaintext `--password` flag to `--bcrypt-password-hash`, matching every other path; it reads the hash on the target rather than shipping the deploy host's copy of it."
- "Legacy `fedimint-gateway-password` files are copied forward to the canonical `fedimint-gateway-hash.pw` name (0600) and never deleted or regenerated, so a node with a working unique credential keeps it. Plan 01-16 owns retirement of the legacy name."

# Phase 1 Plan 11: Remove Every Shipped Fedimint Gateway Credential (FED-07) Summary
**Deleted the six sites that configured a Lightning gateway with a bcrypt hash (and, on one path, a plaintext password) committed to this repository, replaced them with one canonical per-install accessor that refuses to return the known-compromised value, and made every install path fail loudly — or skip the container with a printed reason — rather than fall back to anything shipped.**
## Performance
- **Duration:** ~135 min across two sessions (see Deviations — the first session's executor was killed mid-Task-2 by an SSH disconnect)
- **Completed:** 2026-07-31
- **Tasks:** 2/2
- **Files modified:** 9 (4 Rust, 5 shell)
## Accomplishments
- `container::secrets` gained the canonical trio: `GATEWAY_HASH_SECRET_NAME` (matching the manifest), `ensure_gateway_credential` (idempotent, delegates to `ensure_one`'s existing bcrypt arm so there is one generation implementation), and `gateway_bcrypt_hash` (returns `Err` naming the file when missing/empty/unreadable, and `Err` when the stored value is denylisted).
- `KNOWN_DEFAULT_GATEWAY_HASHES` holds the compromised hash as detection-only data. It is now the single occurrence of that value in the entire tree, and the only function that reads it uses it to *refuse*.
- Five fallback sites deleted: `config.rs`'s `read_secret(..., "$2y$10$t9Yjj…")`, `dependencies.rs`'s `unwrap_or_else` onto the same literal, and the generate-or-default blocks in `first-boot-containers.sh`, `reconcile-containers.sh` and `deploy-to-target.sh`. A sixth — `deploy-tailscale.sh`'s plaintext `|| echo 'archipelago'` — is gone too, along with the `--password` argv it fed.
- The gateway is now unconfigurable without a per-install credential: in Rust the error propagates out of `get_app_config` via `?`; in shell each path skips container creation and prints why.
- Naming unified on the manifest's `fedimint-gateway-hash` / `.pw`, with legacy `fedimint-gateway-password` values copied forward rather than regenerated, so no node with a working unique credential loses it.
- `container-specs.sh` gained a `SPEC_SKIP_REASON` mechanism so a missing credential produces a skipped spec with a message instead of an empty `--bcrypt-password-hash` argument.
## Task Commits
1. **Task 1: End-to-end — a gateway spec that cannot be built without a per-install credential** — Rust accessor, denylist, 5 tests, and the three call-site changes.
2. **Task 2: The shell install paths generate their own credential instead of shipping one** — all five scripts.
## Files Created/Modified
- `core/archipelago/src/container/secrets.rs` — canonical name const, detection-only denylist, `ensure_gateway_credential`, `gateway_bcrypt_hash`, and 5 new tests (fresh generation + 0600 + plaintext verifies against hash, idempotence, named missing-secret error, denylist rejection, per-install uniqueness).
- `core/archipelago/src/api/rpc/package/config.rs` — `get_app_config` now returns `Result<...>`; the `fedimint-gateway` arm calls `ensure_gateway_credential` then `gateway_bcrypt_hash` and propagates. No ports/volumes/network/health/other-argv changes.
- `core/archipelago/src/api/rpc/package/dependencies.rs` — `configure_fedimint_lnd` takes `fedi_hash: &str`; its own read-with-fallback deleted.
- `core/archipelago/src/api/rpc/package/install.rs` — `.await?` on `get_app_config`; resolves the hash once and passes it into `configure_fedimint_lnd`.
- `scripts/first-boot-containers.sh` — htpasswd dependency and generation removed; legacy migration copy; gateway creation skipped with a logged reason when no credential exists.
- `scripts/reconcile-containers.sh` — same pattern.
- `scripts/deploy-to-target.sh` — remote generation block replaced with legacy-migration-only copy; the empty-`FEDI_HASH` literal substitution replaced with a printed NOTE; gateway creation wrapped in an `if [ -n '$FEDI_HASH' ]` guard with an else-branch explaining the skip. The dead `GW_COMMON` variable (its only definition, referenced nowhere) was removed with the literal it carried.
- `scripts/deploy-tailscale.sh` — same generation/fallback removal; container-creation block now reads the target's `fedimint-gateway-hash`, skips with a reason when empty, and uses `--bcrypt-password-hash` in both the lnd and ldk branches.
- `scripts/container-specs.sh` — `SPEC_SKIP_REASON` empty-value guard; secret name and `$`-escaping left untouched as instructed.
## Decisions Made
See `key-decisions` above. The load-bearing one is the `Result` widening of `get_app_config`: the plan left the mechanism open and required the choice be recorded. `Result` was chosen because the alternative (an argv the install path rejects) leaves a defaulted gateway one refactor away from being reachable again, whereas a `?` makes it a compile-time impossibility.
## Deviations from Plan
### Process deviation: executor killed mid-task by an SSH disconnect; plan completed in a second session
**Found during:** Task 2, while editing `scripts/deploy-to-target.sh`
**Issue:** The orchestrating session and all its background agents died when the operator's SSH connection dropped (broken pipe). The 01-11 executor's transcript ends on an unanswered `tool_use`. Task 1 was complete and correct; Task 2 was three scripts done, one left **syntactically broken**, and one never started.
**Resolution:** A follow-on session verified Task 1 against the plan's acceptance criteria (all pass), repaired `deploy-to-target.sh`, and implemented `deploy-tailscale.sh` from scratch following the pattern the dead executor had established in its three finished scripts.
**Files modified:** `scripts/deploy-to-target.sh`, `scripts/deploy-tailscale.sh`
### Auto-fixed Issue: apostrophe inside a single-quoted ssh heredoc broke deploy-to-target.sh
**Found during:** Task 2 verification (`bash -n` failed at line 1953, ~700 lines below the actual edit)
**Issue:** The dead executor's new comment read `…is generated by the daemon's` — inside `ssh "$TARGET_HOST" '…'`, that apostrophe **terminates the single-quoted remote command string**, so the remainder of the block was reparsed as local shell and the error surfaced at an unrelated `fi` far below. This is a live hazard for anyone editing these deploy scripts: prose comments inside single-quoted ssh blocks must not contain apostrophes.
**Resolution:** Reworded to `…is generated by the daemon / via container::secrets::ensure_gateway_credential`. `bash -n` clean. The same rule was applied to all new comments added to `deploy-tailscale.sh`.
**Files modified:** `scripts/deploy-to-target.sh`
## Planner Assumptions — resolved
- **Whether `get_app_config` could return `Result` without a wide refactor:** yes. Every arm wrapped in a single `Ok(match …)`, one call site updated. No behaviour change to any other app.
- **Whether the compromised hash's plaintext is publicly recoverable: UNRESOLVED — and it should not block 01-16.** No bcrypt implementation is available on this box outside the Rust crate (no `python3-bcrypt`, no `passlib`, no node `bcryptjs`, no `htpasswd`), so no candidate list was tested. **Strong lead for 01-16:** `deploy-tailscale.sh`'s plaintext fallback for the very same credential was the literal string `archipelago`, so that is the first candidate to check. Until someone verifies it, 01-16's operator message should assume the plaintext IS recoverable — the value shipped in a public repo either way, so the rotation is mandatory regardless.
## Known Stubs
None.
## Threat Flags
- **T-01-50 / T-01-51 (critical, elevation + spoofing) — mitigated.** No configure path can produce the shipped credential; the accessor refuses it even on a node that already carries it.
- **T-01-52 (information disclosure) — mitigated.** Generation reuses `write_secret` (atomic, 0600); no script logs the value, only that generation was deferred or a container skipped.
- **T-01-53 (DoS by removing the fallback) — mitigated.** No path hard-fails a whole install: the gateway container is skipped with a printed reason and created on a later reconcile once the daemon has generated the credential.
- **Residual, owned by 01-16:** nodes already running a gateway configured with the shipped default keep running it. This plan makes them detectable and unre-configurable with that value; it does not rotate them.
- **T-01-SC:** no packages added.
## Self-Check
- FOUND: `KNOWN_DEFAULT_GATEWAY_HASHES` in `core/archipelago/src/container/secrets.rs` (3 references: doc-linked definition + accessor use + test)
- FOUND: `gateway_bcrypt_hash` used in `config.rs` and `install.rs`
- CONFIRMED: `grep -rl 't9YjjxkiktrlYvjajB'` across `*.rs *.sh *.yml *.json` returns exactly one file — the denylist
- CONFIRMED: `grep -c -- '--password ' scripts/deploy-tailscale.sh` == 0; `grep -c "|| echo 'archipelago'"` == 0
- CONFIRMED: `bash -n` clean on all five scripts
- CONFIRMED: `cargo build -p archipelago` exits 0 (3 pre-existing warnings, none from this plan)
- CONFIRMED: `cargo test -p archipelago` — 999 passed, 2 failed. Both failures are `container::boot_reconciler::tests::{second_pass_fires_after_interval, shutdown_terminates_loop}`, wall-clock-timed loop tests (50ms tick, 5s timeout) that ran while the box was executing two cargo builds and the full vitest suite concurrently. Re-run in isolation: `cargo test -p archipelago boot_reconciler` → **4 passed, 0 failed in 0.29s**. `boot_reconciler.rs` contains no `gateway`/`secrets` references and is untouched by this plan's diff — load flakiness, not a regression.
- CONFIRMED: `npx vitest run` (full frontend suite) exits 0

<objective>
Make the connected-nodes list obey the row: its height tracks the taller sibling beside it and the
list scrolls inside that height, instead of growing until every node fits.
Purpose: UIFIX-02 is a BLOCKER, and it is a regression of an earlier request ("was still meant to
scroll"). Quick task 260729-je5 made the list fill the card's height; what is missing is the other
half — the list must not *drive* the card's height. Today all three tab panes carry
`max-h-72 xl:max-h-none`, so at the `xl` breakpoint where the row becomes two columns the cap is
lifted and nothing bounds the list: it grows to fit every row, stretches the grid row, and the
scrollbar the user expects never appears.
Output: a bounded, sibling-matched card with an internal scroll at the row breakpoint, an unchanged
stacked layout below it, and a test that pins the contract so a future cleanup cannot undo it again.

<read_first>
- `neode-ui/src/views/web5/Web5ConnectedNodes.vue` lines 1-135: the card root
(`glass-card p-6 scroll-mt-24 flex flex-col`), the desktop and mobile header blocks, the four-tab
strip, and the three `v-show` tab panes at lines 57, 90 and 120 — all three currently carrying
`space-y-2 flex-auto min-h-0 overflow-y-auto max-h-72 xl:max-h-none`. Also read the loading and
empty rows inside the trusted pane so you know what renders when the list is empty.
- `neode-ui/src/views/web5/Web5.vue` lines 57-74: the three `grid grid-cols-1 xl:grid-cols-2 gap-6`
rows. The connected-nodes card is the left item of the first row and `Web5NodeVisibility` is its
right sibling. Confirm no `items-start`/`self-start` is applied anywhere on that row — grid's
default `align-items: stretch` is what makes the sibling-matched height work, and this plan must
not add or remove alignment utilities on the row.
- `neode-ui/src/views/web5/Web5NodeVisibility.vue` — read only far enough to see roughly how tall
it renders (it is the sibling whose height the card must adopt). Do not modify it.
- `neode-ui/src/views/dashboard/__tests__/keepAliveTabs.test.ts` — the house convention for a
structural DOM/class pin test in this repo (this is the file the standing rule names as
must-stay-green; read it for its mounting and assertion style, do not change it).
</read_first>
<behavior>
- Mounting the component and reading the trusted pane's class list: it has `overflow-y-auto`, has
`min-h-0`, and has no class that removes its height bound at the row breakpoint.
- The same three assertions hold for the observers pane and the requests pane.
- The pane keeps a capped height below the row breakpoint (the stacked layout is unchanged).
- The card root is a flex column with a height floor at the row breakpoint, so a short sibling
cannot collapse the list area.
- With an empty node list the pane still renders (the existing empty/loading row is present) and
the pane element is still in the tree.
</behavior>
<action>
Write the test file first and confirm it fails.
In `Web5ConnectedNodes.vue`, change only the height/overflow contract:
On each of the three tab panes, replace the current sizing classes so that below the row
breakpoint nothing changes (keep the existing capped height and `overflow-y-auto`, keep basis
`auto` so the auto-height stacked column still sizes to content), and at the row breakpoint the
pane becomes a zero-basis growing flex child with no height cap — `xl:flex-1 xl:basis-0
xl:max-h-none` alongside the existing `min-h-0 overflow-y-auto`. Zero basis is the whole trick:
it makes the pane contribute nothing to the card's intrinsic height, so the grid row is sized by
the sibling alone, `align-items: stretch` gives the card that row height, and `flex-1` then hands
the leftover height to the pane, which scrolls inside it.
On the card root, keep `glass-card p-6 scroll-mt-24 flex flex-col` exactly as it is and add
`min-h-0` plus a row-breakpoint height floor (`xl:min-h-[20rem]`) so a sibling shorter than the
header-plus-tabs block still leaves a usable, scrolling list area rather than a collapsed strip.
Choose the floor to sit close to today's stacked cap so the visual weight of the card is familiar.
Change nothing else. Do not touch the header blocks, the tab strip, the per-row markup, the count
badges, the pulse dot on the requests tab, any `v-show`/`v-if` condition, any script logic, or any
class on `Web5.vue`'s grid rows. Do not add a scrollbar style — the list already scrolls with the
house default below the breakpoint and must look identical above it.

which ports, and how to stop them cleanly.
- `neode-ui/src/views/settings/AccountInfoSection.vue` (grep it for "connected" / "nodes" first) —
the todo flags a second "connected nodes" block living in settings. Determine whether it is the
same list in a different place or unrelated copy, and record the verdict.
</read_first>
<action>
Start the dev preview, open the Web5 tab at a wide viewport (at or above the row breakpoint), and
observe the first row directly. Confirm three things and record each in the SUMMARY with the
viewport width you used:
1. The connected-nodes card and its right-hand sibling are the same height.
2. With more connected nodes than fit, the list scrolls inside the card and the card does not grow
— if the mock backend does not supply enough nodes to overflow, temporarily add rows in the
browser's element inspector to force the condition rather than editing the mock backend, and say
so in the SUMMARY.
3. Narrowing below the row breakpoint restores exactly the previous stacked appearance.
Then settle the second surface: grep the settings section named above for a connected-nodes list.
If it is a genuinely separate list with the same grow-to-fit behaviour, fix it the same way in this
plan and add its file to the plan's `files_modified` in the SUMMARY. If it is unrelated (for
example a count or a link rather than a scrolling list), record that finding and leave it alone.
Do not silently skip this step — the todo explicitly flagged the ambiguity.
Extend the test file with a case for whichever surface the investigation confirmed, so the pin
covers what actually shipped.

## Planner Assumptions (flagged, unresolved)
- **The 20rem floor is a judgement call, not a measured value.** The planner did not render
`Web5NodeVisibility.vue` to learn its height. If the sibling is reliably taller than the floor the
floor never binds and the exact value is invisible; if it is shorter, the floor is what the user
sees. Task 2's dev-preview observation is where that gets confirmed — if the floor looks wrong on
screen, adjust it there and record the final value.

| T-01-55 | Information Disclosure | a bounded, scrolling list hiding a connected node the operator needs to notice | medium | mitigate | The tab strip's existing count badges stay untouched and remain visible above the scroll area, so the total is always readable without scrolling; the acceptance criteria forbid changing them |
| T-01-56 | Spoofing | a long peer-supplied node name overflowing the newly bounded pane and overlapping adjacent chrome | low | accept | Row markup is unchanged by this plan; the panes already truncate as they do today, and this plan alters only the container's height and overflow |
| T-01-57 | Denial of Service | a very large peer list making the card expensive to render | low | accept | The list is already fully rendered today; bounding the container reduces painted area rather than increasing it, and virtualisation is out of scope for a layout fix |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs nothing — template class changes and one vitest file only. If an implementation choice would add a dependency, stop: RESEARCH.md's Package Legitimacy Audit must cover it first, with a blocking human checkpoint for any `[ASSUMED]`/`[SUS]` entry |

# Phase 1 Plan 12: Connected-Nodes Row-Matched Scroll (UIFIX-02) Summary
**Gave the connected-nodes card's three tab panes a zero-basis flex-grow contract so the card's height at the row breakpoint comes from its `Web5NodeVisibility` sibling via Grid's default stretch, with the list scrolling inside that height instead of growing to fit every row — floor tuned to 40rem per Dorian's live-browser feedback.**
## Performance
- **Duration:** ~105 min (across two work sessions, separated by a live-browser verification checkpoint)
- **Completed:** 2026-07-31
- **Tasks:** 2/2 (Task 2's dev-preview portion completed by Dorian directly, not the executor — see Deviations)
- **Files modified:** 2 (1 component, 1 new test file)
## Accomplishments
- All three tab panes (trusted/observers/requests) in `Web5ConnectedNodes.vue` now carry `min-h-0 overflow-y-auto max-h-72 xl:flex-1 xl:basis-0 xl:max-h-none` — below the `xl` breakpoint nothing changed (same cap, same scroll); at `xl` the pane contributes zero intrinsic height, so the grid row is sized by the sibling alone and the pane scrolls inside the leftover height.
- Card root gained `min-h-0 xl:min-h-[40rem]` so a short sibling (e.g. discovery disabled, `Web5NodeVisibility` renders small) still leaves a full, usable list area instead of collapsing to the header+tabs strip.
- New structural test `Web5ConnectedNodesScroll.test.ts` pins this contract (3 tests) so a future cleanup cannot regress it a third time (the todo notes this was already a regression of an earlier fix).
- Settled the ambiguity the originating todo explicitly flagged: the "connected nodes" hits in `settings/AccountInfoSection.vue` are changelog prose describing the feature by name, not a second scrolling list — confirmed by direct grep of all 10 hits, no code change needed there.
- Live-browser verification (sibling-height match at wide viewport, forced-overflow internal scroll, unchanged stacked layout at narrow viewport) was performed by Dorian on his own running `:8100` dev session rather than by the executor spinning up a competing instance.
## Task Commits
Each task was committed atomically, across two rounds (the second correcting the height floor per live feedback):
1. **Task 1: End-to-end — the trusted pane scrolls at a sibling-matched height** - `ceafbcb5` (fix) — added the scroll contract classes + wrote the pinning test (initial floor: `xl:min-h-[20rem]`, the planner's flagged judgement call)
2. **Task 2 correction: raise the height floor to 40rem** - `b5628d96` (fix) — Dorian verified height-match/scroll/stacked-layout were all correct on his own running session but reported the floor was too short with discovery disabled ("should be twice as tall"); floor changed `20rem` → `40rem`, test's expected value updated to match
Both commits pushed to `gitea-ai main`. No separate plan-metadata commit was needed beyond this SUMMARY's own final commit (below).
_Note: this plan's Task 1 was `type="tracer" tdd="true"` — test file written first (RED verified analytically via `git diff` showing the exact classes the test's `toContain`/`not.toContain` assertions depend on), then the fix applied and the test confirmed green (GREEN)._
## Files Created/Modified
- `neode-ui/src/views/web5/Web5ConnectedNodes.vue` - card root: `min-h-0 xl:min-h-[40rem]`; all three tab panes: `xl:flex-1 xl:basis-0 xl:max-h-none` replacing `flex-auto`/no-basis, keeping `min-h-0 overflow-y-auto max-h-72` unchanged. No script-block, header, tab-strip, row-markup, or `Web5.vue` changes (verified via `git diff --stat` showing zero change to `Web5.vue`, and zero `<script` diff lines).
- `neode-ui/src/views/web5/__tests__/Web5ConnectedNodesScroll.test.ts` - new: 3 tests pinning (1) the bounded scroll contract classes on all three panes, (2) the card root's min-h-0/flex-col/`xl:min-h-[40rem]` floor, (3) the empty-state row still rendering for each pane.
## Decisions Made
- Height floor: `xl:min-h-[40rem]` (final, confirmed value) — see key-decisions above for the full reasoning trail (planner's 20rem guess → Dorian's live feedback → 40rem).
- Settings `AccountInfoSection.vue` "connected nodes" surface: confirmed unrelated (changelog prose), left untouched.
- Live-browser verification delegated to Dorian's own already-running dev session rather than the executor starting a competing instance — see Deviations.
## Deviations from Plan
### Auto-fixed Issues
None beyond the planned scope — the height/overflow class changes and test file are exactly what the plan specified (with the floor value corrected per live feedback, which the plan itself flagged as an open judgement call to be settled at this exact step).
### Process deviation: live-browser verification performed by the user, not the executor
**Found during:** Task 2, precondition step ("local dev preview can be started... on :8100")
**Issue:** The session's hard constraints (as initially worded) listed `:8100`/`:5173`/`:5175`/`:5959`/`:3141` as ports the executor must never touch. All of `:8100`, `:5959`, `:5173`, `:5175` were confirmed (via `ss -ltnp`) to already be live processes belonging to running `vite`/mock-backend sessions in this same working tree, so starting a new instance risked colliding with a live session. The executor halted and returned a `checkpoint:human-verify` rather than starting anything or reading from those ports.
**Resolution:** Dorian checked his own already-running `:8100` session directly (a live `vite` dev server on this exact `neode-ui` checkout, which had already hot-reloaded the template change via HMR) and reported: height match, internal scroll, and stacked layout all correct ("we are good"), with the floor value needing to double. The coordinator also clarified mid-execution that the constraint's intent was "never kill/restart/disturb," not "never read from" — read-only observation of an already-running dev server is fine going forward.
**Files modified:** none as a result of this deviation itself (informational); the floor-value correction it produced is `neode-ui/src/views/web5/Web5ConnectedNodes.vue` (commit `b5628d96`).
**Commit:** N/A (process note, not a code fix)
### Auth gates
None encountered.
## Known Stubs
None — no hardcoded empty values, placeholder text, or unwired data introduced by this plan.
## Threat Flags
None — this plan is a template-class-only change plus a new test file; no new endpoints, auth paths, or trust-boundary surface introduced.
## Self-Check: PASSED
- FOUND: neode-ui/src/views/web5/Web5ConnectedNodes.vue (modified, confirmed via git diff)
- FOUND: neode-ui/src/views/web5/__tests__/Web5ConnectedNodesScroll.test.ts (created)
- FOUND commit ceafbcb5 (git log --oneline --all | grep ceafbcb5)
- FOUND commit b5628d96 (git log --oneline --all | grep b5628d96)
- CONFIRMED: `neode-ui/src/views/dashboard/__tests__/keepAliveTabs.test.ts` byte-identical (git diff --stat shows no change) and green in every `npx vitest run` pass during this plan.

<objective>
Make the seed-confirmation tickbox obviously findable on short screens, in a way that looks like it
was always part of the design.
Purpose: UIFIX-03 is a BLOCKER — on a short viewport the tickbox sits below the fold inside the
step's scrolling area while the Continue button stays pinned and disabled in the fixed footer, so
onboarding reads as broken rather than incomplete. The user asked for this to be solved "in a
beautiful way": the fix has to feel intentional and native to the house glass/dark style, not a
bolted-on arrow, and it must be invisible on screens tall enough not to need it.
Output: a bottom scroll cue on the seed step that appears only when it is needed, scrolls the tickbox
into view when activated, and vanishes once the tickbox is on screen.

<read_first>
- `neode-ui/src/views/OnboardingSeedGenerate.vue` — the whole file (262 lines). The structure that
matters: a `h-[100dvh]` outer centring wrapper; a `path-glass-container onb-scroll-container
flex flex-col` card; a `flex-shrink-0` header; the scrolling middle region
(`flex-1 overflow-y-auto overflow-x-hidden px-6 sm:px-8 min-h-0`) that contains the loading
state, the error state, the words/QR tabs, the word grid, the orange warning box and — last —
the confirmation `<label>` with the checkbox bound to `confirmed`; and the `flex-shrink-0`
fixed footer holding the Continue button gated on `confirmed`. Note the existing
`watch(confirmed, …)` that focuses the Continue button, and the `onb-lock-spin` scoped keyframes
block at the bottom (the house pattern for a small scoped animation in this file).
- `neode-ui/src/style.css` — find the `.onb-scroll-container` rules (around line 1146 and a
breakpoint block around line 1162) to see what the shared onboarding container already does.
Read only; this plan must not modify the shared stylesheet, because these classes are used by
every other onboarding step.
- `neode-ui/src/components/RefreshIndicator.vue` — the house convention for a small, purely
presentational overlay component with a scoped keyframes animation, for style reference.
- `neode-ui/src/components/SendBitcoinModal.vue` — grep it for `prefers-reduced-motion` and copy
that media-query syntax verbatim for the cue's guard, so all reduced-motion guards in this repo
read identically.
</read_first>
<behavior>
- With the scroll region reporting more content than fits and the tickbox below the visible area,
the cue element is in the DOM.
- With the scroll region reporting no overflow, the cue element is absent from the DOM entirely —
not merely hidden, so it can occupy no space and cause no shift.
- Scrolling to the bottom (tickbox now inside the visible area) removes the cue.
- Activating the cue calls the scroll-into-view path for the tickbox and does not change
`confirmed`.
- While `loading` is true, or while `errorMessage` is set and no words have arrived, the cue is
absent regardless of overflow.
- Ticking the box removes the cue.
</behavior>
<action>
Write the test file first and confirm it fails. In jsdom there is no layout engine, so drive the
measurements by defining `scrollHeight`, `clientHeight` and `scrollTop` on the scroll element with
`Object.defineProperty` and dispatching a `scroll` event — assert on what the component renders in
response, not on computed geometry.
In `OnboardingSeedGenerate.vue`:
Add a template ref to the existing scrolling middle region and one to the confirmation label. Add
a `showScrollCue` ref and an `updateScrollCue()` function that sets it true only when all of these
hold: words are present, not loading, the scroll element reports more scrollable content below the
current position, the confirmation label's bottom lies below the scroll element's visible bottom,
and `confirmed` is still false. Call it from a `scroll` listener on the scroll element, from a
`resize` listener on the window, from a `ResizeObserver` on the inner content wrapper (the word
grid changes height when the user switches between the words and QR tabs), from a watcher on
`words`, and from a watcher on `confirmed`. Remove every listener and disconnect the observer in
`onUnmounted` alongside the existing `stopTimers()` call.
Render the cue as a `v-if="showScrollCue"` overlay positioned against the scrolling region's
bottom edge, inside a `Transition` so it fades rather than pops. Compose it from two layers, both
`pointer-events-none` except the button itself:
a soft gradient fade from transparent to the card's own dark backdrop across roughly 64px, so the
content appears to slide under the edge rather than being cut off; and, centred on it, a small
glass pill — the house `bg-black/60` + `backdrop-blur` treatment, `rounded-full`, `text-white/75`
at `text-xs`, with the orange accent (`#fb923c` / `text-orange-400`) used only for a downward
chevron drawn as inline 24×24 `stroke-width="2"` SVG per the icon convention in
`01-UI-SPEC.md`. Copy for the pill: **"One more step below"**. Give the chevron a gentle 2s
ease-in-out vertical bob of no more than 3px, defined in the file's existing scoped style block
next to `onb-lock-spin`, and guard it with the `prefers-reduced-motion` media query copied from
`SendBitcoinModal.vue`.
Make the pill a real `<button type="button">` whose click smooth-scrolls the confirmation label
into view (`scrollIntoView({ behavior: 'smooth', block: 'center' })`) and nothing else — it must
never touch `confirmed`, never focus or enable the Continue button, and never call `proceed()`.
Give it an `aria-label` naming what it reveals so it is reachable and understandable without
sight, and make sure it is keyboard-focusable in the natural order.
Do not alter the header, the words/QR tab strip, the word grid, the QR block, the warning box, the
tickbox markup, the footer, the Continue button, or any existing class on the card or the scroll
region. Do not edit `style.css`. Add nothing that renders when `showScrollCue` is false.

<action>
Start the dev preview and open the seed-generate step. Check it at three heights and record each
observation in the SUMMARY with the exact viewport used:
1. A short viewport (for example 1280×620, a small laptop or mobile landscape). Expected: the cue
is visible, reads as part of the card rather than an overlay bolted on top of it, and clicking
it brings the tickbox into view; the cue then disappears.
2. A tall viewport (for example 1440×1000). Expected: no cue at all, and the step is
pixel-identical to before this change — compare against the current build if you are unsure.
3. A narrow phone viewport (for example 390×740). Expected: the cue reads correctly at that width
and does not overlap the word grid or the warning box.
If the cue does not look like it belongs at any of the three, adjust the gradient depth, the pill
size, or the copy until it does, then re-run the test suite. This is the "beautiful way" the user
asked for — treat a cue that looks bolted on as a failure of this task, not a matter of taste.
Then settle the scope question the requirement leaves open. Run
`grep -l 'type="checkbox"' neode-ui/src/views/Onboarding*.vue` and, for every step that has a
confirmation tickbox inside a scrolling region, check it at the short viewport. If another step has
the same defect, apply the same cue there in this plan, add the file to the plan's
`files_modified` in the SUMMARY, and extend the test. If no other step does, record the grep
output and the verdict. Do not assume the seed step is the only one.

## Planner Assumptions (flagged, unresolved)
- **The seed-generate step is assumed to be the one the user hit.** The todo says "verify it's this
step". The planner confirmed this step has a confirmation tickbox at the bottom of a scrolling
region with a pinned, disabled Continue button below it — the exact reported symptom — but did not
enumerate every onboarding view. Task 2 closes this with a grep and a per-file verdict rather than
leaving it as an assumption.
- **The chosen affordance is the scroll cue, not the sticky-footer alternative.** The todo listed
three candidate approaches. The cue was chosen because the other two change the tall-screen
appearance (a sticky footer alters the card at every height; an auto-scroll moves content the user
did not ask to move), and the standing rule forbids changing existing visuals. If the cue proves
unsatisfying at Task 2, raise it rather than silently switching approach.
<threat_model>
## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| displayed recovery seed → screen | This step renders 24 words that grant full control of the node, identities and wallet |
| user consent → onboarding progression | The tickbox is the recorded acknowledgement that the seed was written down |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-58 | Repudiation | an affordance that advances onboarding without a genuine acknowledgement | high | mitigate | The prohibition and an explicit test case forbid the cue from touching `confirmed`; the cue only scrolls |
| T-01-59 | Information Disclosure | a new overlay covering seed words so a user transcribes them wrongly and loses recovery | high | mitigate | The cue renders only at the bottom edge of the scroll region and only while content remains below; Task 2 requires checking at a narrow width that it does not overlap the word grid |
| T-01-60 | Denial of Service | scroll and resize handlers firing continuously on a low-power onboarding device | low | mitigate | The handler is a few property reads and one boolean assignment with no allocation or RPC; listeners and the observer are removed in `onUnmounted` |
| T-01-61 | Tampering | the shared onboarding stylesheet being edited and silently restyling every other step | medium | mitigate | All new CSS is scoped to this component, and an acceptance criterion fails the task if `style.css` shows any diff |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs nothing — one component and one vitest file. If an implementation choice would add a dependency, stop: RESEARCH.md's Package Legitimacy Audit must cover it first, with a blocking human checkpoint for any `[ASSUMED]`/`[SUS]` entry |

# Phase 1 Plan 13: On-Brand Scroll Cue for the Onboarding Tickbox (UIFIX-03) Summary
**Added a measurement-driven scroll cue to the seed step so the confirmation tickbox is never silently below the fold on a short screen — and made it structurally impossible for that cue to appear on a screen tall enough not to need it.**
## Performance
- **Duration:** ~70 min (across two sessions — see Deviations)
- **Completed:** 2026-08-01
- **Tasks:** 2/2
- **Files modified:** 2 (1 view, 1 new test file)
## Accomplishments
- A sticky-bottom cue inside the seed step's scroll region: a gradient scrim with a glass pill ("One more step below") and a bobbing chevron, styled to the house dark/glass language rather than a bolted-on arrow.
- Visibility is derived from real geometry — `scrollHeight > clientHeight` for overflow, then a `getBoundingClientRect()` comparison of the tickbox's bottom against the scroll container's bottom. On a tall viewport the element does not render at all, so tall screens are byte-identical to before.
- Activating the cue smooth-scrolls the tickbox into view and does nothing else; a test asserts `confirmed` is untouched, so the affordance can never become a way to skip the confirmation.
- The cue also stays hidden while the seed is generating and after the box is ticked, and its chevron animation is disabled under `prefers-reduced-motion`.
- Listener/observer setup was moved onto both `onMounted` paths — previously the sessionStorage-restore path returned early, which would have left a user navigating back to this step with no cue at all.
## Files Created/Modified
- `neode-ui/src/views/OnboardingSeedGenerate.vue` — refs on the scroll container, content wrapper and tickbox label; `updateScrollCue()` measurement; `revealConfirm()`; scroll/resize/ResizeObserver wiring with matching teardown in `onUnmounted`; the cue markup and its scoped CSS (fade transition, chevron bob, reduced-motion guard).
- `neode-ui/src/views/__tests__/OnboardingScrollCue.test.ts` — 6 tests pinning the full contract.
## Deviations from Plan
### Process deviation: executor killed mid-verification by an SSH disconnect
**Found during:** post-implementation verification
**Issue:** The orchestrating session and its agents died when the operator's SSH connection dropped. This plan's implementation and test file were complete and on disk but uncommitted, and no SUMMARY had been written.
**Resolution:** A follow-on session re-ran the suite (6/6 green), confirmed the full frontend suite was green, wrote this SUMMARY, and committed.
**Files modified:** none beyond the original work
## Known Stubs
None.
## Threat Flags
None — a presentational affordance with no new endpoint, no auth surface, and no state mutation. The one safety-relevant property (that it cannot set confirmation state) is asserted by test.
## Live-browser verification (added post-commit)
Run against the built bundle on the `:4321` preview via Playwright, at the three viewports the
original executor's script targeted:
| Viewport | Cue shown | After activating it |
|---|---|---|
| 1280×620 (short) | yes | tickbox in view, `checked=false`, cue gone |
| 1440×1000 (tall) | **no** — element never renders | n/a |
| 390×740 (narrow) | yes | tickbox in view, `checked=false`, cue gone |
A geometry probe confirmed the mechanism rather than just the outcome: after activation the scroll
container sits at its maximum offset (`scrollTop == scrollHeight - clientHeight`) with the tickbox's
bottom above the container's (442 vs 454 at 1280×620; 622 vs 634 at 390×740), which is exactly the
condition the cue's visibility is derived from.
One caveat worth recording: the *first* run reported the cue still visible after activation at
1280×620. It did not reproduce on any subsequent run, and the geometry probe showed the cue absent at
600 ms, 1500 ms and 3000 ms after the click at both viewports. The first run was the cold load
immediately after a rebuild, so it is almost certainly smooth-scroll settling — but it is written
down rather than discarded, because it is the one observation that contradicts the contract.
## Self-Check: PASSED
- FOUND: `neode-ui/src/views/OnboardingSeedGenerate.vue` (modified)
- FOUND: `neode-ui/src/views/__tests__/OnboardingScrollCue.test.ts` (created, 6 tests)
- CONFIRMED: `npx vitest run` full frontend suite green (102 files, 822 tests)
- CONFIRMED: live browser, 3 viewports (table above)

<objective>
Make a purchased picture open where every other picture in the app opens — the lightbox — and make
the wait visible while it loads.
Purpose: two user-reported issues that phase 2 classified as pre-existing and captured rather than
fixed. `Cloud.vue`'s `viewPaidItem()` calls `window.open(url, '_blank', 'noopener')` (introduced
f3393581, 2026-07-22), so Paid Files is the one media surface that leaves the app. The same function
issues `content.owned-get` with a 60-second timeout and renders no loading affordance at all, and its
`catch` swallows every failure — so a slow or failed open is indistinguishable from a click that did
nothing. Both live in the same twelve lines, so they are fixed together.
Output: a small viewer composable with tested per-mime routing, a paid-items lightbox in Cloud, an
inline house loading state on the row, real error surfacing, and a recorded verdict for every other
surface phase 2 flagged as slow.

- `neode-ui/src/views/Cloud.vue` lines 150-178 (the Paid Files tab rows: each row is a
`glass-card p-3 flex items-center gap-3 cursor-pointer` div with `@click="viewPaidItem(it)"`, an

(`lightboxIndex`/`lightboxItems` refs and `handlePreview`, the working example of driving that
component). Also note `loadError` and the `alert-error` block at line 369 — the error surface
this plan reuses rather than inventing one.
- `neode-ui/src/components/cloud/MediaLightbox.vue` — the whole file. What matters: it takes
`items: FileBrowserItem[]` and filters them by extension through `getFileCategory`, so a
synthetic item's `name` must carry a real extension; it calls `props.fetchBlobUrl(item.path)`
for images and `props.streamUrl(item.path)` for video/audio when supplied; it caches returned
URLs in its own `urlCache` and revokes every one of them in `onUnmounted`. That last point
decides URL ownership: whatever this plan hands to the lightbox must not also be revoked by
Cloud.
- `neode-ui/src/views/PeerFiles.vue` lines 172-190 — the existing house treatment for exactly this
interaction: a per-item `playing === item.id` guard rendering a 3×3 border spinner with an
"Opening..." label inside the button. Reuse this treatment; do not invent a new one.
- `neode-ui/src/api/filebrowser-client.ts` — the `FileBrowserItem` shape, so the synthetic item is
structurally valid rather than cast.
- `neode-ui/src/composables/useAudioPlayer.ts` — the `play(url, name)` contract the audio branch
already uses.
</read_first>
<behavior>
- Given a purchased item with an `image/*` mime, `open()` fetches it once, then exposes it as a
lightbox item with a resolvable object URL; it does not call `window.open`.
- Given a `video/*` mime, same — routed to the lightbox.
- Given an `audio/*` mime, `open()` routes to the audio player and never to the lightbox.
- Given a mime with no in-app viewer, `open()` falls back to the existing browser-tab behaviour.
- `opening` is set to the item's key for the whole duration of the fetch and cleared in every exit
path, including the failure path.
- A rejected or timed-out fetch sets an error message and clears `opening`; it does not throw past
the caller.
- Calling `open()` twice for the same item while the first call is in flight issues one RPC.
- The synthetic lightbox item's `name` ends in the real file extension so the lightbox's own
category filter accepts it.
</behavior>
<action>
Write the test file first and confirm it fails. Stub the RPC client and `URL.createObjectURL`/
`atob` at the module boundary; jsdom has no real blob decoding, so assert on what was requested and
what was routed where, not on byte content.
Create `neode-ui/src/composables/usePaidItemViewer.ts` exporting `usePaidItemViewer()` returning at
least: `opening` (a ref holding the key of the item currently being fetched, or null), `error` (a
ref holding a user-facing message or null), `lightboxItems`, `lightboxIndex`, `resolveBlobUrl(path)`
and `open(item)`. Move the existing fetch-and-decode chain out of `Cloud.vue` verbatim — same RPC
method, same params, same 60-second timeout, same base64 decode, same blob construction. Then
branch on the resolved mime: audio hands off to `useAudioPlayer` exactly as today; image and video
build a synthetic `FileBrowserItem` (a stable synthetic `path` key, a `name` that is the item's
basename so its extension survives, `isDir: false`, and the size from the item), register the
created object URL against that path in an internal map that `resolveBlobUrl` reads, and set
`lightboxItems`/`lightboxIndex` to show it; anything else keeps today's browser-tab behaviour
including its existing revoke timer.
URL ownership, stated once so there is exactly one owner: URLs handed to the lightbox are revoked
by the lightbox on unmount — the composable must not schedule a revoke for those. URLs handed to
the audio player keep today's behaviour. URLs opened in a browser tab keep today's revoke timer.
Guard concurrency by keying on the item and returning early when that key is already in `opening`.
Replace the empty `catch` with one that sets `error` to a short user-facing message (reuse the tone
of the existing copy in this view) and clears `opening` in a `finally`.
In `Cloud.vue`: import the composable, delete the old `viewPaidItem` body and delegate to
`open(it)`, and wire two things into the template. First, the Paid Files row gets the PeerFiles
loading treatment — while `opening` matches that row's key, render the 3×3 border spinner and an
"Opening…" label in place of the "Paid" pill, and make the row non-interactive for the duration so
a second click cannot queue. Second, add a second `MediaLightbox` instance below the existing one,
bound to the composable's `lightboxItems`/`lightboxIndex`, with `fetch-blob-url` and `stream-url`
both pointing at `resolveBlobUrl`, and `@close` clearing the composable's index. Surface `error`
through the view's existing `loadError` alert rather than adding a new error element.
Change nothing else in `Cloud.vue` — not the tab strip, not the category pills, not the Folders,
My Files or Peer Files sections, not the peer cards, not the existing own-files lightbox instance,
not any cached-resource key, TTL or `persist` flag.

<files>neode-ui/src/composables/__tests__/usePaidItemViewer.test.ts</files>
<read_first>
- `.planning/phases/02-ui-performance/02-FINDINGS.md` — the `## Outstanding` section and the
`### Per-surface verdict` block under `## Re-measurement (gap closure)`. These name the surfaces
to audit: Discover, Server, Web5, Fleet, AppDetails, OpenWrtGateway, MarketplaceAppDetails and
Wallet-send. Read them for what each surface's cost actually is — several are *revisit*
regressions on already-cached views, which is the one case where a loader would be a PERF-02
regression rather than a fix.
- `neode-ui/src/components/RefreshIndicator.vue` — the whole file, including its doc comment: it
renders only in the `refreshing` state and deliberately renders nothing for `loading`, because a
first load is the view's own skeleton's job. This is the rule that decides which affordance a
surface needs.
- `neode-ui/src/components/SkeletonCard.vue` — the house first-load skeleton, and
`neode-ui/src/components/cloud/FileGrid.vue`'s skeleton block for the grid variant.
- `.planning/phases/02-ui-performance/02-CONTEXT.md` — the D-05 rules on what a background-refresh
indicator may and may not show, so anything added here matches decisions already locked.
</read_first>
<action>
Audit each surface named above. For each one, determine two things from the code: does a first
open (no cache) render a loading affordance today, and is the open genuinely slow and uncached
rather than a cached revisit. Record a one-line verdict per surface in the SUMMARY as a table with
columns: surface, file, existing affordance, genuinely slow first open, action taken.
Add a house loading affordance only where the audit proves both a genuinely slow uncached first
open and no existing affordance — a `SkeletonCard`/`FileGrid`-style skeleton for a list or grid, a
`RefreshIndicator` only for background revalidation. Never gate a new affordance on a
`refreshing` state for a first load, and never add one to a cached revisit path; PERF-02's
no-spinner-on-revisit guarantee outranks this requirement wherever they meet, and phase 2's
verdict is that the named revisit regressions are client-side render cost, not a missing loader.
If a surface needs a fix, implement it in this plan and add its file to `files_modified` in the
SUMMARY. If every surface already has one — which the planner's own read of these files suggests
is likely, with `Cloud.vue`'s paid-open being the single genuine gap — say so explicitly with the
evidence, and do not add a loader for its own sake. A verdict of "already covered" is a valid
outcome; an unrecorded surface is not.
Extend the test file with a case pinning that the paid-open loading state is driven by the fetch
being in flight and not by any cached-resource `refreshing` state, so a later refactor cannot turn
it into a revisit spinner.

## Planner Assumptions (flagged, unresolved)
- **Documents keep the browser-tab path.** UIFIX-04's text names pictures, and the app has no in-app
document viewer; routing a PDF into a media lightbox would be a downgrade, not a fix. This is a
deliberate scope boundary, not an omission — recorded here so it is visible rather than silent. If
the user wants documents in-app too, that is a new requirement, not a gap in this one.
- **The planner's read suggests every other named surface already has a loading affordance** (grep
showed loading/skeleton markup in Server, Web5, Fleet, AppDetails, MarketplaceAppDetails,
Marketplace, Apps, OpenWrtGateway and the Discover app grid). Task 2 re-verifies rather than
assuming, because a grep hit is not proof that the affordance covers the *first uncached open*.
<threat_model>
## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| peer-supplied purchased bytes → app-origin viewer | Content bought from another node is now rendered inside the app origin instead of a separate tab |
| purchase records → rendered row | Paid amounts and purchase history are financial data already marked `persist: false` |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-62 | Elevation of Privilege | peer-supplied bytes rendered in-origin instead of an isolated tab | high | mitigate | The content is delivered as a blob object URL with the mime the backend reports and rendered only through `<img>`/`<video>` elements the lightbox already uses for local files; no `srcdoc`, no `innerHTML`, no iframe, and the no-in-app-viewer branch keeps today's separate-tab behaviour for anything that is not an image or a video |
| T-01-63 | Information Disclosure | a purchased-content object URL outliving the view and remaining fetchable | medium | mitigate | The prohibition fixes exactly one owner per URL; the lightbox revokes what it is given on unmount, and the composable is forbidden from scheduling a competing revoke for those |
| T-01-64 | Repudiation | a failed open being indistinguishable from a click that did nothing | medium | mitigate | The empty `catch` is replaced with one that sets a user-facing error through the view's existing alert, and a test case asserts the failure path both surfaces and clears state |
| T-01-65 | Denial of Service | repeated clicks queuing multiple 60-second fetches of large purchased files | medium | mitigate | The `opening` key guard returns early for an in-flight item, the row is made non-interactive while loading, and a test case pins single-fetch behaviour |
| T-01-66 | Spoofing | a purchased item's declared mime steering it to the wrong viewer | low | accept | Mime comes from the same backend response the current code already trusts for its blob type; this plan changes routing, not provenance, and tightening mime provenance belongs to the content pipeline, not a viewer fix |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs nothing — one new composable, one view edit, one vitest file. If an implementation choice would add a dependency, stop: RESEARCH.md's Package Legitimacy Audit must cover it first, with a blocking human checkpoint for any `[ASSUMED]`/`[SUS]` entry |

provides:

tech-stack:
added: []
patterns:
- "Fetch-before-show: the composable fetches+decodes the purchased blob BEFORE opening the lightbox, so the lightbox's own fetchBlobUrl/streamUrl props resolve instantly from an internal map — the row's own 'opening' spinner covers the real (possibly-slow) network wait, not the lightbox's own (now-instant) internal loading flash."
- "One key, one owner: opening/inFlight/urlByPath are all keyed by the same paidItemKey(onion+content_id) formula the row's v-for :key already uses, so the row's spinner condition and the composable's dedup guard can never drift apart."

key-decisions:
- "Documents (and any other mime with no in-app viewer) keep the browser-tab fallback unchanged — this is a scope boundary from the plan, not an omission."
- "All eight surfaces phase 2 flagged as slow-opening (Discover, Server, Web5, Fleet, AppDetails, OpenWrtGateway, MarketplaceAppDetails, Wallet-send) are CACHED-REVISIT render-cost regressions, not missing-first-load-affordance gaps — every one already shows a loading affordance on its genuinely slow path (first load or the specific in-flight async op), so no loader was added anywhere in Task 2. Adding one to any of them would put a spinner on a cached revisit, a direct PERF-02 regression."
- "URL ownership: the lightbox revokes every URL it is handed, on unmount, exactly as it already does for My Files/Peer Files. The composable never schedules a competing revoke for a URL routed to the lightbox — only the browser-tab fallback path keeps its own revoke timer, unchanged from before."
patterns-established:
- "Row-level loading + non-interactive guard for a fetch-then-route action, reusing PeerFiles.vue's existing 3x3 spinner + 'Opening...' treatment rather than inventing new visual language."

# Phase 01 Plan 14: Paid Files lightbox + loading-state audit Summary
**Purchased pictures/videos now open in the app's own MediaLightbox with a visible "Opening…" row spinner and real error surfacing, replacing `window.open()` + a swallowed catch; the eight other surfaces phase 2 flagged as slow are confirmed cached-revisit render-cost regressions, not missing loaders, so none of them were touched.**
## Performance
- **Duration:** ~30 min
- **Started:** 2026-07-31T22:00Z (approx, from first read)
- **Completed:** 2026-07-31T22:30Z
- **Tasks:** 2 (Task 1 tracer + Task 2 audit)
- **Files modified:** 3
## Accomplishments
- New `usePaidItemViewer()` composable: moves `Cloud.vue`'s inline `content.owned-get` fetch/decode chain into a reusable, unit-tested unit with per-mime routing (image/video → lightbox, audio → bottom-bar player, everything else → today's browser-tab fallback), a single-flight `open()` guard keyed on `onion+content_id`, and a `resolveBlobUrl` the lightbox calls to read the already-fetched URL.
- `Cloud.vue`'s Paid Files row: `window.open()` is gone entirely (`grep -c 'window.open'` = 0); the row now shows a spinner + "Opening…" label (reusing `PeerFiles.vue`'s existing treatment verbatim) for the fetch's duration and becomes non-interactive so a second click can't queue a second fetch.
- A second `MediaLightbox` instance added below the existing My Files one, fed the composable's `lightboxItems`/`lightboxIndex` and `resolveBlobUrl` for both `fetch-blob-url` and `stream-url`.
- The composable's `catch` sets a real, user-facing `error` message that Cloud.vue surfaces through its existing `loadError`/`alert-error` block — no more silent failure.
- Task 2 audit: every one of the eight surfaces phase 2's findings named (Discover, Server, Web5, Fleet, AppDetails, OpenWrtGateway, MarketplaceAppDetails, Wallet-send) confirmed as a cached-revisit client-side render-cost regression with an existing first-load/first-fetch affordance already in place — no new loader added anywhere.
## Task Commits
1. **Task 1: End-to-end — a purchased picture opens in the lightbox, with the wait visible** - `bc9a210c` (fix)
- Follow-up type-check fix (vue-tsc caught two possibly-undefined array reads `npx vitest run` alone doesn't flag): `4a8925f0` (fix)
2. **Task 2: Settle the slow-open inventory — verdict per surface, loader only where genuinely missing** - no code changes; audit-only, documented below (the pinning test required by this task's acceptance criteria was already written as part of Task 1's test file, see "opening is not derived from a background-refresh flag" test)
**Plan metadata:** (this commit)
## Files Created/Modified
- `neode-ui/src/composables/usePaidItemViewer.ts` - fetch/decode/route/loading/error composable for purchased items
- `neode-ui/src/composables/__tests__/usePaidItemViewer.test.ts` - 9 tests: per-mime routing (image/video/audio/no-viewer), extension-carrying synthetic item, loading-state, the not-derived-from-refresh pin, error surfacing, double-click dedup
- `neode-ui/src/views/Cloud.vue` - `viewPaidItem()` now delegates to the composable; row loading/error UI; second `MediaLightbox` instance
## Per-Surface Slow-Open Verdict (Task 2)
Audited against `.planning/phases/02-ui-performance/02-FINDINGS.md`'s "Per-surface verdict" and "Accepted deviations" sections (the authoritative measured evidence) plus a direct grep of each surface's own loading-state code, per the plan's own instruction to re-verify rather than assume a grep hit covers the first uncached open.
| Surface | File | Existing affordance (first/genuinely-slow open) | Genuinely slow first open? | Action taken |
|---|---|---|---|---|
| Discover | `neode-ui/src/views/Discover.vue` | `catalogResource.entry.loadState === 'loading'` drives a loading message (`loadingCommunity`, line 303) | No — 02-FINDINGS: 0 RPC confound-free reading, regression is Apps-tab-KeepAlive-transit render/reactivation cost on **revisit**, not the first uncached open | None — first-load already covered; a revisit regression is out of scope for a loader (would violate PERF-02) |
| Server | `neode-ui/src/views/Server.vue` | Multiple `animate-spin` loading indicators per-section (e.g. line 91, 250) plus keyed `useCachedResource` per load group (02-06) | No — 02-FINDINGS/02-09: component instance confirmed to genuinely survive the round-trip (`vm.$.uid` proof); regression is 7 cached resources' reactivation cost on **revisit**, RPC count *improved* (8→2) | None — same reasoning; revisit-only cost |
| Web5 | `neode-ui/src/views/web5/Web5.vue` | `loadingDidDoc` text indicator (line 44) plus each sub-card's own `useCachedResource` | No — 02-FINDINGS: strongest zero-overlap evidence of pure client-side reactivation cost on a confirmed-surviving instance, 0 RPC throughout, all three measurement runs | None — same reasoning; revisit-only cost |
| Fleet | `neode-ui/src/views/Fleet.vue` | `animate-spin` loading state (lines 64, 93) | No — 02-FINDINGS: instance survives (confirmed), 0 RPC either time, the most severe of the split-signal regressions (330ms→2631ms) but purely a revisit/reactivation cost | None — same reasoning; revisit-only cost |
| AppDetails | `neode-ui/src/views/AppDetails.vue` | `credentialsLoading` computed from `credentialsResource.loadState.value === 'loading'`, passed to its credentials section (line 44/206) | No — 02-FINDINGS: RPC count *improved* (2→1) via keyed `useCachedResource` (02-03); the keyed-lookup/re-render cost now exceeds what the eliminated fetch saved, on revisit | None — same reasoning; revisit-only cost |
| OpenWrtGateway | `neode-ui/src/views/server/OpenWrtGateway.vue` | Explicit "Loading skeleton" block (line 522) with a documented first-load-only condition (line 102-104 comment) | No — 02-FINDINGS: same split-signal class as AppDetails; RPC evidence confounded by Server-tab transit but `revisitMs` alone shows the regression is on the cached path, and the skeleton is already gated to first-load-only | None — same reasoning; revisit-only cost, and the surface deliberately avoids showing a skeleton on revisit already (matches PERF-02) |
| MarketplaceAppDetails | `neode-ui/src/views/MarketplaceAppDetails.vue` | `v-if="loading"` full-card skeleton with `animate-spin` (line 7-8) | No — 02-FINDINGS: RPC evidence confounded by Home-tab transit; only `package.versions` is a trustworthy call and it improved; regression (if any residual) reads as revisit render cost, and the raw `remounted: false` reading is flagged as likely the same selector-ambiguity artifact 02-09 proved, not new instance caching | None — first-load skeleton already present and correctly gated |
| Wallet / send flow (`SendBitcoinModal.vue`) | `neode-ui/src/components/SendBitcoinModal.vue` | `feeEstimateLoading` ref renders `'…'` in place of the fee figure while the fee-estimate call is in flight (lines 388-419) | No — 02-FINDINGS: **cleared as environmental noise** in the re-measurement (median dropped below both prior runs); the separate, still-open anomaly (revisit consistently slower than first-visit, 0 RPC) is because `BaseModal`'s `v-if` always fully remounts the modal — not a missing loader, and out of this plan's `files_modified` (`SendBitcoinModal.vue` isn't in this plan's scope; carried forward in 02-FINDINGS' Outstanding section) | None — the modal's own async op (fee estimate) already has a first-load affordance; the remount-cost anomaly is a pre-existing, separately-tracked issue this plan doesn't own |
**No affordance was added to any cached-revisit path in this plan.** PERF-02's no-spinner-on-revisit guarantee is preserved everywhere — the only genuinely slow, uncached, first-open gap that existed (`Cloud.vue`'s `viewPaidItem()` / `content.owned-get`, 60s timeout, zero indicator) is the one fixed in Task 1; every other named surface's slow-open regression is client-side render/reactivation cost on an already-cached revisit, which a loader cannot fix and must not paper over.
## Decisions Made
- Documents (no in-app viewer) deliberately keep the browser-tab fallback — a scope boundary named explicitly in the plan, not a gap.
- No new loader was added anywhere in Task 2 — see the per-surface verdict table above; every named surface's regression is revisit-only render cost, confirmed by phase 2's own measured evidence (`02-FINDINGS.md`), not a missing first-load affordance.
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Fixed two TS strict-null-check errors caught by `npm run build`'s `vue-tsc -b` pass**
- **Found during:** Task 1, post-commit `npm run build` verification
- **Issue:** `viewer.lightboxItems.value[0].name` — TS2532 "Object is possibly 'undefined'" on two array-index test assertions. `npx vitest run` alone doesn't type-check test files under this project's config, so this only surfaced during the build's own `vue-tsc -b` step.
- **Fix:** Optional-chained both reads (`viewer.lightboxItems.value[0]?.name`).
- **Files modified:** `neode-ui/src/composables/__tests__/usePaidItemViewer.test.ts`
- **Verification:** `npm run build` exits 0 after the fix; `npx vitest run` for the file still 9/9 green.
- **Committed in:** `4a8925f0`
---
**Total deviations:** 1 auto-fixed (blocking, build type-check)
**Impact on plan:** Test-only, no behavior change. No scope creep.
## Issues Encountered
None beyond the above.
## Verification
- `cd neode-ui && npx vitest run src/composables/__tests__/usePaidItemViewer.test.ts` — 9/9 passed.
- `cd neode-ui && npx vitest run` — 99 test files / 812 tests, all green (`keepAliveTabs.test.ts` confirmed byte-for-byte unmodified via `git status --short` and still passing within that run).
- `cd neode-ui && npx vue-tsc --noEmit` — clean.
- `cd neode-ui && npm run build` — succeeds; `grep -rq 'Opening…' ../web/dist/neode-ui/assets/Cloud-*.js` confirms the new string reached the bundle.
- `grep -c 'window.open' neode-ui/src/views/Cloud.vue` = 0; `grep -c 'MediaLightbox' neode-ui/src/views/Cloud.vue` = 4 (import + 3 usages incl. the doc comment referencing it); `grep -c 'usePaidItemViewer' neode-ui/src/views/Cloud.vue` = 3.
- `git diff -- neode-ui/src/views/Cloud.vue | grep -c "^-.*key: 'cloud\."` = 0 — no cached-resource key touched.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- UIFIX-04 and UIFIX-06 are both closed for their named gap (Paid Files). No blockers for future phase-1 plans.
- Carried-forward, unrelated-to-this-plan items already tracked in `02-FINDINGS.md`'s Outstanding section (Discover/Server/Web5/Fleet/AppDetails/OpenWrtGateway split-signal render-cost regressions, Wallet-send's remount anomaly) remain open there — this plan's audit reconfirmed them but did not fix them, per the plan's own explicit instruction that a cached-revisit render-cost regression is not a UIFIX-06 loader gap.

---
<objective>
Make picture-in-picture behave like a handoff: the lightbox gets out of the way with a fluid
animation, and the session then survives everything that used to kill it.
Purpose: two user reports, both classified by phase 2 as pre-existing. `src/utils/pip.ts`'s
`togglePip()` (f72d4b92, 2026-07-23) only toggles the browser API and never touches
`MediaLightbox.vue`'s visibility, so entering PiP leaves a full-screen backdrop sitting over the app.
And the session dies on a tab change because the `<video>` lives inside a view that used to unmount
outright — phase 2's KeepAlive work removed the unmount, which is what makes survival achievable now,
but the element is still a descendant of the view tree and of a `Teleport`, both of which a
deactivation can move. The fix is to stop relying on where the element happens to live: hand it to a
body-level custodial host at the moment PiP begins.
Output: a session composable owning the custodial host, a handoff animation on the lightbox, explicit
buffering tolerance, and tests that pin all three.

- `neode-ui/src/utils/pip.ts` — the whole file (19 lines). Note that `pipSupported` is a
module-level `const` evaluated at import time: that is why a test cannot stub support after
import, and why this task adds a lazy probe alongside it rather than replacing it outright.
- `neode-ui/src/components/cloud/MediaLightbox.vue` lines 20-31 (the PiP button, `v-if` gated on
`pipSupported`, calling `togglePip(videoEl)`) and lines 76-87 (the `<video>` element: `ref`,
`:src="currentUrl"`, `:key="currentUrl"`, `controls`, `autoplay`). The `:key` binding matters —
any change to `currentUrl` destroys and recreates the element, which is one of the ways a
session can die.
- `neode-ui/src/App.vue` lines 1-60 — how app-level persistent UI is mounted (`GlobalAudioPlayer`
is the precedent for something that must outlive route changes). Read for the precedent only;
this plan does not modify `App.vue`, because a composable-owned body-level node needs no
template anchor and therefore cannot disturb the dashboard DOM shape that
`src/views/dashboard/__tests__/keepAliveTabs.test.ts` pins.
- `neode-ui/src/composables/useAudioPlayer.ts` — the house convention for a module-singleton
composable holding cross-view media state.
</read_first>
<behavior>
- `adopt(video)` moves the element into the session host, and the host is a child of
`document.body`.
- After `adopt`, unmounting the component that originally rendered the video leaves the element
still connected to the document.
- `release()` removes the element from the host and leaves nothing behind under `document.body`.
- The host is created at most once no matter how many times the composable is called, and its
computed presentation is non-interactive and off-screen.
- `active` is true between adopt and release and false outside that window.
- `isPipSupported()` reads the document at call time, so a test can stub support before or after
the module is imported.
- `togglePip`'s existing behaviour and signature are unchanged.
</behavior>
<action>
Write the test file first and confirm it fails. jsdom has no picture-in-picture API, so stub
`document.pictureInPictureEnabled`, `document.pictureInPictureElement`,
`HTMLVideoElement.prototype.requestPictureInPicture` and `document.exitPictureInPicture` in the
test setup, and drive state by dispatching `enterpictureinpicture` / `leavepictureinpicture`
events on the element.
In `neode-ui/src/utils/pip.ts`: add `export function isPipSupported(): boolean` that performs the
same three checks at call time instead of at import time. Leave the existing `pipSupported` const
and `togglePip` exactly as they are so nothing that imports them today changes behaviour.
Create `neode-ui/src/composables/usePipSession.ts` as a module singleton exporting
`usePipSession()` returning at least `active` (readonly ref), `element` (readonly ref) and the
functions `adopt(video: HTMLVideoElement)` and `release()`.
The host: create it lazily on first `adopt`, once per module, as a plain `div` appended to
`document.body` with an identifying `data-` attribute. Style it so it can never be seen or
interacted with and can never affect layout — fixed position, off-screen, one pixel, zero opacity,
no pointer events, `aria-hidden`, and not focusable. Do not give it a visible size or a z-index
that could ever place it over the app.
`adopt(video)`: append the element into the host (this both keeps it in the document and detaches
it from whatever view owned it), record it as `element`, set `active`, and attach a
`leavepictureinpicture` listener that calls `release()`. Adopting while a session is already
active must release the previous one first rather than leaking it.
`release()`: remove the adopted element from the host, pause it, clear its `src` and call `load()`
so no media keeps buffering, drop the listener, clear `element`, and clear `active`. Leave the
host itself in place for reuse — an empty off-screen div costs nothing and re-creating it on every
session is churn.
Do not import this composable anywhere yet; Task 2 wires it. Keep it free of Vue lifecycle hooks —
it is a module singleton, and a lifecycle hook in a bare composable is exactly the silent-no-op
class phase 2 hit twice.

keep animating with.

<behavior>
- Dispatching `enterpictureinpicture` on the lightbox's video causes the component to emit `close`
exactly once.
- Before that emit, the video has been adopted by the session, so it is no longer a descendant of
the lightbox's own subtree.
- The handoff class is applied to the backdrop for the duration of the animation and only on the
PiP path — closing with the close button or Escape applies no handoff class.
- After the component unmounts following a handoff, the video is still connected to the document.
- Dispatching `leavepictureinpicture` releases the session.
- The component's declared props and emits are unchanged.
</behavior>
<action>
Write the test cases first and confirm they fail.
In `MediaLightbox.vue`, wire the session. On the video element, add `enterpictureinpicture` and
`leavepictureinpicture` handlers — listen for the events rather than inferring from the button
click, so a PiP entered by any route (the browser's own control, a keyboard shortcut) behaves the
same.
On enter: adopt the video into the session, add a `lightbox-pip-handoff` class to the backdrop, and
emit `close` when the handoff animation finishes — drive that off `transitionend` with a bounded
fallback timer so a browser that skips the transition still closes. Order matters and must be
exactly this: adopt first, animate second, emit last. Adopting first is what makes the element
survive the unmount that the emit triggers.
Design the handoff so it reads as the video moving into the picture-in-picture window rather than a
dismissal: the backdrop's blur and opacity fall away while the content scales down slightly and
drifts toward the corner the PiP window occupies, over roughly 300ms on the house easing. Keep it
scoped, keep it on the existing `.lightbox-backdrop`/content elements rather than restructuring the
markup, and guard the motion with the `prefers-reduced-motion` media query copied from
`SendBitcoinModal.vue` — under reduced motion the handoff becomes an immediate close, never a
lingering one.
On leave: call the session's release. Because the lightbox has already unmounted by then, the
session's own listener from Task 1 is the primary path; the component-level handler exists for the
case where PiP is exited while the lightbox is somehow still mounted, and must be idempotent with
it.
Switch the PiP button's `v-if` from the import-time `pipSupported` const to `isPipSupported()` so
the button's presence is testable.
Do not change `props`, `defineEmits`, `close()`'s emitted event, the normal-close transition, the
navigation arrows, the keyboard handler, the media-loading logic, `urlCache`, or the `onUnmounted`
revoke. Plan 01-14 adds a second instance of this component with the same prop set; a contract
change would break it.

<files>neode-ui/src/components/cloud/MediaLightbox.vue, neode-ui/src/components/__tests__/MediaLightboxPip.test.ts</files>
<precondition>The local dev preview can be started (`cd neode-ui && npm run dev:mock` serves the UI on :8100 against the mock backend) and it serves at least one video — jsdom has no picture-in-picture implementation, so only a Chromium-based browser can prove the session actually survives</precondition>
<read_first>
- `neode-ui/src/components/cloud/MediaLightbox.vue` as left by Task 2 — specifically `prev()`,
`next()`, the `watch(currentItem, …)` that calls `loadMedia` and sets `currentUrl` to null, and
the `:key="currentUrl"` binding on the video. Each of these can destroy the playing element.
- `neode-ui/src/views/dashboard/keepAlive.ts` (or wherever `KEEP_ALIVE_PATHS` is defined — grep for
it) — enough to understand that a main-tab switch now deactivates rather than unmounts the view,
which is the change that makes tab survival reachable at all.
</read_first>
<action>
Close the remaining ways a session can die.
Add explicit `waiting` and `stalled` handlers on the video that do nothing but record that
buffering is happening — no pause, no reload, no src change, no release. Their existence is the
point: they document that buffering is a tolerated state and give a test something to assert
against, so a later change cannot quietly add teardown there. Do not add a `pause` handler that
releases the session; a pause during buffering and a pause by the user are indistinguishable from
the element, and only an explicit exit from picture-in-picture may end a session.
Guard the destroy-the-element paths: while the session is active, `prev()` and `next()` return
early, and the `currentItem` watcher does not reset `currentUrl`. In the normal flow the lightbox
has already closed by then and these are unreachable, but they are cheap insurance against the
exact class of bug this requirement is about.
Add test cases: a `waiting` event leaves the session active; a `stalled` event leaves the session
active; `next()` during an active session does not change the rendered item.
Then prove it in a browser, because jsdom cannot. Start the dev preview in Chromium, open a video
in the lightbox, and record each of these in the SUMMARY:
1. Click the picture-in-picture button. Expected: the lightbox animates away as a handoff — it
should read as the video moving, not as a dismissal — and the video keeps playing in the PiP
window.
2. With PiP playing, switch between main tabs several times. Expected: playback continues
uninterrupted.
3. With PiP playing, force a buffering pause (throttle the network in devtools, or seek far ahead).
Expected: it resumes and the PiP window stays.
4. Close the PiP window explicitly. Expected: playback stops and nothing is left behind — check the
element inspector for a stray video under `document.body`.
5. Open the lightbox again and close it with the close button and with Escape. Expected: exactly
the animation it had before this plan.
If the handoff does not read as a handoff, adjust the animation and re-record; the requirement
asks for a fluid on-brand transition, so a jarring one is a failed task.

## Planner Assumptions (flagged, unresolved)
- **The custodial-host approach was chosen over "keep the lightbox mounted but invisible".** The todo
offered both. Keeping the component mounted would leave the video inside a `Teleport` inside a
`KeepAlive`d view, and both of those move their subtrees on deactivation — a moved element is a
removed element as far as the picture-in-picture spec is concerned. The planner did not verify Vue
3.5's exact teleport-under-deactivation behaviour, and deliberately chose the design that does not
depend on the answer. If the executor establishes that the simpler approach is safe, raise it rather
than switching silently.
- **The PiP window's corner is browser- and user-controlled**, so the handoff's drift direction is a
best-effort convention, not a guaranteed match. Task 3's browser observation is where it is judged.
<threat_model>
## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| in-app media playback → an OS-level window outside the app's own chrome | Picture-in-picture puts content in a surface the app no longer draws |
| adopted element → document lifetime | An element deliberately kept alive past its owner's unmount is state that outlives its normal cleanup |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-67 | Information Disclosure | private media continuing to play in a floating window after the user believes they closed it | high | mitigate | The lightbox closing is now an explicit consequence of the user starting PiP, not a side effect; release pauses, clears `src` and calls `load()`, and Task 3's fourth browser observation requires confirming nothing is left behind |
| T-01-68 | Denial of Service | an orphaned adopted element buffering a large stream forever after its owner is gone | high | mitigate | Release is bound to `leavepictureinpicture` inside the session itself, so it fires even when the component that adopted the element no longer exists; a test asserts the host is empty after release |
| T-01-69 | Tampering | the custodial host being reachable or clickable and intercepting input | medium | mitigate | The host is off-screen, one pixel, zero opacity, pointer-events none, `aria-hidden` and non-focusable, and the prohibition forbids any state in which it can affect layout |
| T-01-70 | Elevation of Privilege | a second component adopting into an already-active session and leaking the first element | medium | mitigate | `adopt` releases any existing session first; a test covers the repeated-adopt path |
| T-01-71 | Repudiation | a contract change to the lightbox silently breaking the parallel plan 01-14 | medium | mitigate | An explicit prohibition plus a diff-based acceptance criterion fail the task if props or emits change |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs nothing — two new source files, two edits, two vitest files. If an implementation choice would add a dependency, stop: RESEARCH.md's Package Legitimacy Audit must cover it first, with a blocking human checkpoint for any `[ASSUMED]`/`[SUS]` entry |

# Phase 1 Plan 15: PiP Handoff That Survives the Lightbox (UIFIX-05) Summary
**Made picture-in-picture a handoff rather than a dismissal: the video is re-parented to a body-level custodial host before the lightbox closes, so an active PiP session survives the unmount — and the close animates as the video moving out rather than the overlay disappearing.**
## Performance
- **Duration:** ~85 min (across two sessions — see Deviations)
- **Completed:** 2026-08-01
- **Tasks:** 2/2
- **Files modified:** 3 (1 new composable, 1 component, 1 new test file)
## Accomplishments
- `usePipSession()` owns a singleton off-screen host under `document.body`. `adopt(video)` moves the element there so it outlives the view that rendered it; `release()` pauses, detaches and tears down. A `leavepictureinpicture` listener attached at adopt time is the primary release path.
- `MediaLightbox` listens for `enterpictureinpicture`/`leavepictureinpicture` on the video itself, so any route into PiP behaves identically.
- The handoff ordering (adopt → animate → emit close) is enforced and documented in-place; a test asserts adoption happens before the single `close` emit.
- The backdrop gains a `lightbox-pip-handoff` class on the PiP path only, with `transitionend`-driven close and a 350 ms fallback for browsers that skip the transition (including reduced-motion, where the duration is zero).
## Task Commits
1. **Task 1: singleton PiP session with body-level custodial host** — `3288a02d` (feat)
2. **Task 2: lightbox handoff wiring, handoff animation, and test suite** — committed with this SUMMARY
## Files Created/Modified
- `neode-ui/src/composables/usePipSession.ts` — the singleton session and custodial host (committed in `3288a02d`).
- `neode-ui/src/components/cloud/MediaLightbox.vue` — PiP event handlers, handoff class + CSS, `transitionend`/timer close path, and the `pipSupported` → `isPipSupported()` call-site update.
- `neode-ui/src/components/__tests__/MediaLightboxPip.test.ts` — 5 tests, with jsdom stubs for the picture-in-picture APIs it does not implement.
## Deviations from Plan
### Process deviation: executor killed mid-verification by an SSH disconnect
**Found during:** post-implementation verification
**Issue:** Task 1 had been committed (`3288a02d`); Task 2's component changes and test file were complete on disk but uncommitted when the orchestrating session and its agents died with the operator's SSH connection.
**Resolution:** A follow-on session re-ran the suite (5/5 green), confirmed the full frontend suite was green, wrote this SUMMARY, and committed the remainder.
**Files modified:** none beyond the original work
## Known Stubs
None in product code. The test file stubs `pictureInPictureEnabled`, `requestPictureInPicture` and `exitPictureInPicture` because jsdom implements none of them; jsdom also logs "Not implemented: HTMLMediaElement.prototype.pause/load" to stderr during the release test — noise, not failure.
## Threat Flags
None — no new endpoint or trust boundary. The one lifecycle risk (an orphaned element left attached to `document.body` after PiP ends) is closed by `release()` being idempotent and wired to both the session's own listener and the component handler.

- "A node already carrying a unique credential is left completely alone — detection matches the known defaults only, never 'anything I did not generate this run' (FED-07 adjacency edge)"
- "Rotation runs at most once per affected node: after it completes, later reconcile ticks detect nothing and change nothing (FED-07 idempotence)"
- "A rotation the operator can see: it is announced in the node's logs naming the app and that credentials changed, and it never prints the credential itself"
- "After rotation the operator has a supported way to obtain the new gateway credential, so rotating does not lock them out of their own gateway"
- "A rotation that cannot complete leaves the previous working state intact and reports an error rather than leaving a gateway configured against a credential nobody holds (FED-07 failure-surfacing)"

<objective>
Get the nodes that are already running on the shipped gateway credential off it, without touching
their data.
Purpose: plan 01-11 stops new installs from ever taking a shipped credential, but it does nothing for
the nodes that already did. Those gateways answer to a credential published in this repository, so
until they rotate, FED-07 is only half closed — and the requirement is explicit that existing installs
carrying the default get a migration path. The repo's standing rule bounds how: migrations never
destroy data — preserve `/var/lib/archipelago/<app>`, secrets, credentials, ports and adoption
container names, and keep a rollback path.
Output: detection against the denylist plan 01-11 established, rotation through the recreate machinery
that already preserves data, an operator-visible announcement, and a sign-off on a real node.

<name>Task 1: End-to-end — a node carrying the default rotates itself and keeps its data</name>
<files>core/archipelago/src/container/secrets.rs, core/archipelago/src/container/prod_orchestrator.rs</files>
<read_first>
- `core/archipelago/src/container/secrets.rs` as left by plan 01-11 — the
`KNOWN_DEFAULT_GATEWAY_HASHES` denylist, `ensure_gateway_credential`, `gateway_bcrypt_hash`, the
shared bcrypt generation helper, and the atomic 0600 `write_secret`. Rotation reuses all of it;
write no new generation or file-writing code.
- `core/archipelago/src/container/prod_orchestrator.rs` around line 3227 and line 3245 — the
comment naming the per-app generated secrets (`fmcd-password`, `fedimint-gateway-hash`, …) and
the `crate::container::secrets::ensure_generated_secrets(&self.secrets_dir, manifest)?` call.
This is the tick that runs on every reconcile and the natural place to hang detection.
- `core/container/src/manifest.rs` — grep for `secret_env_hash` and read its definition and every
use. This is the existing mechanism by which a changed secret drives a container recreate, and
it is what makes rotation preserve data: the recreate path it feeds already keeps the data
directory, ports, volumes and container name. Reuse it rather than stopping and removing the
container by hand.
- `apps/bitcoin-ui/manifest.yml` lines 8-45 — the in-repo precedent for "the password rotated, so
the rendered bytes changed, so the container is recreated". Read it for how a rotation is
expected to propagate on this platform.
- `core/archipelago/src/container/boot_reconciler.rs` — enough to determine whether boot has its
own separate path that also needs the call, or whether it funnels through the same reconcile
step. Record the finding; if it needs the call too, add that file to `files_modified` in the
SUMMARY.
</read_first>
<behavior>
- Given a secrets dir whose gateway hash file contains a denylist entry, rotation replaces it with
a freshly generated pair and reports that it rotated.
- Given a secrets dir whose gateway hash is not on the denylist, rotation changes nothing and
reports that it did not rotate — including when the value is one nobody recognises.
- Given a secrets dir with no gateway hash at all, rotation changes nothing and reports that it did
not rotate; generation is `ensure_gateway_credential`'s job, not rotation's.
- Running rotation twice on the same affected dir rotates once; the second run is a no-op.
- After rotation the new hash is not on the denylist and its `.pw` sibling verifies against it.
- Rotation touches no file other than the gateway credential pair — every other file in the
secrets dir is byte-identical afterwards.
</behavior>
<action>
Write the tests in `secrets.rs`'s `mod tests` first and confirm they fail. Use `tempfile::tempdir`
the way the existing tests in that module do, and seed the affected case by writing a denylist
entry into the hash file. Include a case that seeds several unrelated secret files alongside it and
asserts they are untouched.
Add `pub fn rotate_compromised_gateway_credential(secrets_dir: &Path) -> Result<bool>` to
`secrets.rs`. It reads the gateway hash file; if it is absent or unreadable it returns `Ok(false)`
without writing; if its trimmed value is not an exact match for a denylist entry it returns
`Ok(false)`; only on an exact match does it generate a replacement pair through the same helper
`ensure_gateway_credential` uses and return `Ok(true)`. Because the underlying write is the
existing atomic temp-file-plus-rename, a failure mid-rotation leaves the previous file in place —
that is the rollback path, and it should be stated in the function's doc comment so nobody later
"improves" it into a truncate-in-place.
Wire it into `prod_orchestrator.rs` immediately alongside the existing `ensure_generated_secrets`
call. When it returns `true`, log at info level that the Fedimint gateway credential was rotated
because the node was carrying a publicly known default, that the gateway will be recreated, and
where the operator can obtain the new one — and never log the value. Then make the recreate happen
through the existing `secret_env_hash` change-detection path rather than by stopping or removing
the container directly: the hash file changed, so the resolved secret env changes, so the platform's
own recreate machinery fires with the data directory, ports, volumes and container name all
preserved. If that path does not fire for this app for some reason you discover, do not hand-roll a
remove-and-run; stop and record what you found, because a hand-rolled recreate is the exact
anti-pattern CLAUDE.md names.
Settle the operator-recovery question and record the answer. The plaintext already lands at
`fedimint-gateway-hash.pw`, 0600, rootless. Determine whether the app-credentials surface in the UI
(`neode-ui/src/views/Credentials.vue` and whatever RPC feeds it) already exposes per-app generated
credentials. If it does, confirm the rotated value appears there and say so. If it does not, the
log line must name the exact path an operator reads, and the SUMMARY must record that a UI surface
is a gap with the file that would own it. Do not leave "how does the operator get the new password"
unanswered — rotating a credential the user cannot retrieve is a lockout, not a fix.
Do not change the gateway's ports, volumes, data directory, network, capabilities, health check or
any other manifest-driven property.

<task type="checkpoint:human-verify" gate="blocking">
<name>Task 2: Confirm the rotation on a real node</name>
<what-built>
FED-07 in full, ready to run on a node:
- No code path in the tree can configure a Fedimint gateway with a credential that shipped with
the repository. The five fallback sites (two in the Rust orchestrator, three in the install and
deploy scripts) are gone, along with the plaintext password fallback in the Tailscale deploy
path. The one surviving copy of the old hash is a denylist used only to detect it.
- Every install now takes its credential from the per-install secret the manifest already
declared, generated at 0600 by `container::secrets`.
- A node that is already carrying the old default rotates itself on its next reconcile tick and
is recreated around its existing data directory, ports and container name.
</what-built>
<how-to-verify>
Run this on archi-dev-box. Note that archy-x250-dev has been offline since phase 2 — do not wait
for it; single-node verification with the second-node gap recorded honestly is the expected
pattern here.
1. **Before you change anything, record the current state.** On the node, check whether the
gateway credential file currently holds the old shipped value, and whether a gateway container
is running. Note both. This is what tells you whether you are testing the rotation path or the
already-clean path — say which one you got.
2. **Deploy this phase's build to archi-dev-box only.** Use the dev-pair deploy path, not a
release, not an OTA, and not the Tailscale alpha-tester path. Record the exact command.
3. **Watch the rotation.** Follow the node's logs across a reconcile tick. Expected if the node was
affected: one info line saying the gateway credential was rotated because a publicly known
default was in use, naming where to get the new one — and no credential value anywhere in the
log. Expected if the node was already clean: no rotation line at all.
4. **Confirm the credential is now unique.** Read the gateway hash file on the node and confirm it
is not the old shipped value, and that its file mode is 0600 and it is owned by the rootless
service user, not root.
5. **Confirm the data survived.** List `/var/lib/archipelago/fedimint-gateway` and confirm its
contents are the same ones that were there in step 1 — the gateway's own state must not have been
reinitialised. Confirm the container came back with the same name and the same published ports.
6. **Confirm the gateway actually works.** Check the container is running and healthy, and that its
admin endpoint answers. Then authenticate to it with the new credential from the path the log
line named. Expected: the new credential works. Then try the old shipped one. Expected: rejected.
7. **Confirm a fresh install is unique too.** If practical, uninstall and reinstall the gateway on
the node and confirm the credential it comes up with differs from the one from step 4 — that is
the per-install property, and it is the whole point of the requirement.
8. **Confirm nothing else moved.** Run `tests/lifecycle/run-gate.sh` on the node (the gate runs
on-node, never over RPC) and confirm it is still green. This plan changed orchestrator reconcile
behaviour, which is exactly the case CLAUDE.md says to re-run the gate for. A single clean pass
is enough here; the 5× run is Phase 3's criterion.
If any step fails, say which numbered step and what you saw — that becomes the gap list rather than
a re-run of the whole plan.
</how-to-verify>
<resume-signal>Type "approved" to sign off FED-07, or describe the issues by step number.</resume-signal>
</task>
</tasks>
## Planner Assumptions (flagged, unresolved)
- **Whether archi-dev-box is actually affected is unknown to the planner.** Its gateway may have been
provisioned by a path that generated a unique credential. Step 1 makes the executor establish which
case they are in and say so, rather than reporting a green run that never exercised the rotation. If
the node is clean, the rotation path still needs proving — seed the old value into the credential
file on the node deliberately, then re-run steps 3 to 6, and record that you did.
- **Whether the UI already exposes per-app generated credentials** was not verified by the planner.
Task 1 makes it an explicit finding with a named owning file if it turns out to be a gap.

## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| gateway admin API → network | The credential being rotated is the only gate on Lightning gateway administration |
| reconcile tick → running container | An automated rotation recreates a live, funded service without asking |
| node logs → operator and anyone who can read them | The rotation announcement crosses this boundary |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-72 | Elevation of Privilege | a node continuing to answer to the published default after the code fix ships | critical | mitigate | Detection and rotation run on the same reconcile tick that already materialises secrets, so an affected node heals without operator action; step 6 proves the old credential is rejected afterwards |
| T-01-73 | Denial of Service | rotation recreating the gateway repeatedly, or in a loop, on every tick | high | mitigate | Rotation is denylist-exact and therefore self-terminating — the rotated value is not on the denylist, so the next tick is a no-op; an idempotence test and step 3's log observation both cover it |
| T-01-74 | Information Disclosure | the new credential appearing in a log line, status output or deploy transcript | high | mitigate | An explicit prohibition, the log line is specified to name a path rather than a value, and step 3 requires confirming no value appears in the log |
| T-01-75 | Tampering | a hand-rolled remove-and-recreate losing the gateway's data directory | critical | mitigate | The action forbids hand-rolled teardown, routes the recreate through the existing `secret_env_hash` path, and an acceptance criterion greps the diff for teardown primitives; step 5 verifies the data on the node |
| T-01-76 | Repudiation | signing off without ever exercising the rotation because the node happened to be clean | high | mitigate | Step 1 forces the executor to declare which case they are in, and the planner assumption requires deliberately seeding the affected state if the node is clean |
| T-01-77 | Denial of Service | an operator locked out of their own gateway by a rotation they cannot recover from | high | mitigate | Task 1 requires the recovery path to be settled and named in the log line before this plan is done; step 6 proves the new credential actually authenticates |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs nothing — two Rust edits. If an implementation choice would add a crate, stop: RESEARCH.md's Package Legitimacy Audit must cover it first, with a blocking human checkpoint for any `[ASSUMED]`/`[SUS]` entry |
</threat_model>
<verification>
- `cd core && cargo test -p archipelago` — green.
- The blocking checkpoint's eight steps, run on archi-dev-box, with the affected-or-clean case declared.
- `tests/lifecycle/run-gate.sh` green on-node after the change.
</verification>
<success_criteria>
- An affected node rotates itself once, keeps its data, ports and container name, and comes back healthy.
- The old shipped credential no longer authenticates; the new one does.
- A fresh install produces a different credential again.
- The rotation is announced without ever printing the value, and the operator has a named way to retrieve it.
- The second dev-pair node's absence is recorded as a gap rather than glossed over.

# Phase 1 Plan 16: Rotate Existing Installs Off the Shipped Gateway Credential (FED-07) Summary
**Task 1 rotates the credential correctly and was proven to do so on a real node. But the checkpoint DISPROVED the assumption it rests on: the rotated credential never reaches the running container, because the Quadlet path does not restart units and the gateway is classified restart-sensitive. FED-07 remains open.**
## Status
**FED-07 is NOT closed, and this plan alone cannot close it.** The checkpoint ran on archi-dev-box on
2026-08-01 and found that rotation does not propagate to the running gateway. A follow-up plan is
required — see the checkpoint result below.
## Accomplishments
- `rotate_compromised_gateway_credential(secrets_dir) -> Result<bool>` in `container::secrets`:
reads the canonical hash file, returns `Ok(false)` for absent/unreadable/unique/unrecognised, and
only on an **exact** denylist match writes a fresh pair and returns `Ok(true)`.
- `write_bcrypt_pair(dir, name)` factored out of `ensure_one`'s `Bcrypt` arm so there is exactly one
bcrypt-generation implementation, called by both generation and rotation.
- Wired into `resolve_dynamic_env` beside `ensure_generated_secrets`, gated on the gateway's app id,
with an info-level announcement that names the *path* to the new plaintext and never the value.
- Six new tests covering rotate-on-denylisted (including 0600 modes and that the `.pw` sibling
verifies against the new hash), no-op-on-unique, no-op-on-unrecognised, no-op-on-absent,
idempotence, and four bystander secrets left byte-identical.
## Findings the plan asked for
### Boot reconciler needs no separate call
`boot_reconciler` calls `reconcile_all()` → `reconcile_all_with_mode()` → per-manifest
`ensure_running_with_mode()` (prod_orchestrator.rs:1714) → `resolve_dynamic_env()`
(prod_orchestrator.rs:1914) → the rotation call. `install_fresh` reaches it by the same route.
So boot and reconcile funnel through one chokepoint and **no boot-specific wiring was added**;
`boot_reconciler.rs` is not in `files_modified`.
### ✅ RESOLVED 2026-08-02: the carve-out closes it, proven on the same node
The failure documented below was fixed and re-verified on archi-dev-box.
**The fix.** Rotation now records the app id in a `credential_rotated` set on the orchestrator, and
the drift check consumes that flag to recreate the container **even when the app is
restart-sensitive**, with a `WARN` naming the reason. It deliberately mirrors the published-port
carve-out sitting a few lines above it in the same function, which already makes exactly this trade
for exactly this reason: a container that is already non-functional (there) or already compromised
(here) is not protected by leaving it running. No teardown was hand-rolled — the existing recreate
path does the work.
**The design call.** Restart-sensitivity protects *working* services. A gateway answering to a
credential published in this repository is not working, it is compromised, and an attacker with
gateway admin can drain Lightning liquidity. Indefinite exposure loses to a few seconds of restart.
The alternative — rotate but only raise an operator alert — was rejected because the monitoring
system fires alerts from metric thresholds only (`check_alerts(&MetricSnapshot)`), so it would have
needed new event-alert plumbing to deliver something strictly weaker than just fixing it.
**Before / after on the same box, same scenario:**
| | Before (15:51, first checkpoint) | After (06:39, re-run) |
|---|---|---|
| Credential file | rotated ✅ | rotated ✅ |
| Container recreated | ❌ never — same PID 25 min later | ✅ 4s after rotation, PID 3923125 → 148426 |
| Running credential | the compromised default | matches the file (`636d6031…`) |
| Log | "leaving running restart-sensitive app untouched" ×4 and counting | "recreating restart-sensitive app: its admin credential was rotated off a publicly known default…" |
Post-recreate state: container healthy, **same name**, **same ports** (8176/9737), `gatewayd.db`
intact at 18 files with `IDENTITY` present, credential `0600 archipelago:archipelago`, 32 containers
untouched, and **zero repeat rotations** on subsequent ticks (the rotated value is not denylisted, so
it is self-terminating — T-01-73 holds).
Covered by three new tests: `rotating_a_compromised_credential_flags_the_app_for_recreate`,
`a_unique_credential_does_not_flag_the_app`, `a_second_pass_does_not_re_flag_the_app`.
---
### ⛔ ORIGINAL CHECKPOINT RESULT (2026-08-01) — retained: this is what the fix had to defeat
**Run on archi-dev-box, 2026-08-01.** The code-reading conclusion below was **wrong in practice**,
which is exactly why the plan made this a blocking checkpoint. The rotation works; the propagation
to the running container does not.
Observed: rotation fired ~15s after restart, wrote a fresh unique credential, and logged correctly.
But **25 minutes later the running gatewayd process was still using the pre-rotation credential.**
`/proc/<pid>/environ` for PID 1 held the old value while the file and the podman secret held the new
one. The orchestrator says why, in its own log lines:
```
Quadlet unit drift-synced — file rewritten, .service NOT restarted
(operator restart picks up new config) app_id=fedimint-gateway
container drift detected during boot reconcile;
leaving running restart-sensitive app untouched app_id=fedimint-gateway
```
Two independent guards, both deliberate:
1. **The Quadlet path rewrites the `.container` unit but never restarts the `.service`.** The unit
file was rewritten at 15:51:36 (same second as the rotation) carrying the new
`secret-env-hash=de9870c642a515f7` label — so the definition updated correctly. Systemd does not
apply a changed unit to a running container without a restart.
2. **`fedimint-gateway` is classified restart-sensitive**, so the drift check *detects* the change on
every reconcile tick and then deliberately leaves the container alone. That line repeated at
15:51, 15:53, 15:54, 15:56 — it will repeat forever.
**Consequence: on a real affected node, rotation makes the credential file unique but the gateway
keeps answering to the compromised one indefinitely** — until an unrelated reboot or a manual
restart. Worse, the operator reading `fedimint-gateway-hash.pw` gets a password the running gateway
does not accept, which is the lockout risk T-01-77 inverted.
Confirmed the fix works when applied: `systemctl --user restart fedimint-gateway.service` produced a
new PID whose `FEDI_HASH` is the rotated value, container healthy, same name, same ports, marker file
and `gatewayd.db` intact.
**Deliberately NOT hand-rolled.** The plan's action says: "If that path does not fire for this app for
some reason you discover, do not hand-roll a remove-and-run; stop and record what you found." So this
is recorded, not patched. The fix belongs in a follow-up and has to answer a real design question:
a compromised credential is arguably the one case that should override restart-sensitivity — or,
failing that, the rotation must raise an operator-facing "restart required" alert rather than logging
into the void.
### What the checkpoint DID prove
| Step | Result |
|---|---|
| 1. State recorded | Node was CLEAN; affected state seeded deliberately (plan's Planner Assumption) |
| 2. Deploy | `install -m0755` to `/usr/local/bin/archipelago` + `systemctl restart archipelago`; rollback kept at `archipelago.bak-pre-fed07` |
| 3. Rotation announced | ✅ One info line, fired once, names the `.pw` path, **no credential value in the log** |
| 4. Credential unique | ✅ Third distinct value (not the default, not the pre-test original), `0600 archipelago:archipelago` |
| 5. Data preserved | ✅ Marker file and all 13 `gatewayd.db` files incl. `IDENTITY` intact; same container name; same ports 8176/9737 |
| 5. Container recreated | ❌ **FAILED — see above** |
| 6. Auth proof | ⚠️ Not obtainable: `gateway-cli` in this image returns the same "Invalid request" for a correct and an incorrect password, so it cannot distinguish them. Substituted PID-1 `environ` comparison, which is stronger evidence of *which* credential is in force. |
| 7. Fresh install differs | ⏸ Not run |
| 8. `run-gate.sh` | ⏸ Not run |
Also proved incidentally: **restarting `archipelago` does not kill containers on this box** — 29/29
and later 31/31 survived, and the orchestrator logged "Adopted 31 existing container(s)". The
CLAUDE.md "restart SIGKILLs containers" rule does not apply under `ARCHIPELAGO_USE_QUADLET_BACKENDS=true`
with podman in the user slice (the service is `system.slice`/`KillMode=control-group`; the containers
live in `user-1000.slice/…/libpod-*`, a different cgroup entirely).
### Original code-reading conclusion (retained — it is what the checkpoint disproved)
`resolve_dynamic_env` computes `secret_env_content_hash(&secret_bearing)` over the resolved
secret-bearing env and stores it as `manifest.app.container.secret_env_hash`
(prod_orchestrator.rs:3309). The drift check (prod_orchestrator.rs:3374) inspects the running
container's `SECRET_ENV_HASH_LABEL` and returns "drifted" when it differs from the expected hash,
which drives the existing recreate. The gateway's `FEDI_HASH` comes from the rotated file, so a
rotation necessarily changes that hash and therefore the label comparison.
**This is a code-reading conclusion. It has not been observed firing on a node** — that is Task 2
step 5, and it is the single most important thing the checkpoint proves.
### Operator recovery: the surface exists but does NOT cover this app — a real gap
- The UI path is live: `Apps.vue` calls `package.credentials` with an `app_id` before launching an
app and renders a credentials modal from the response.
- The backend, `handle_package_credentials` in
`core/archipelago/src/api/rpc/package/install.rs:2093`, is a hardcoded per-app if-chain covering
**only `filebrowser` and `photoprism`**. Every other app, including `fedimint-gateway`, falls
through to `Ok(json!({ "credentials": [] }))`.
- **Consequence:** after rotation the operator has no in-UI way to obtain the new gateway password.
The recovery path is the file the log line names: `/var/lib/archipelago/secrets/fedimint-gateway-hash.pw`
(0600, service user), readable over SSH.
- **Gap owner:** `handle_package_credentials` in `core/archipelago/src/api/rpc/package/install.rs`.
Adding a `fedimint-gateway` arm that reads the `.pw` sibling would close it; the UI needs no change.
Deliberately not done here — this plan's `files_modified` is scoped to two files, and that handler
belongs to the app-credentials surface, not to FED-07's rotation.
## Adjacent finding — NOT part of this plan, raised deliberately
`apps/photoprism/manifest.yml:35` sets `PHOTOPRISM_ADMIN_PASSWORD=archipelago`, and
`handle_package_credentials` hands that same literal back to the UI. That is a shipped default
credential in a manifest — the same class of defect as FED-07, on a different app. Every node running
PhotoPrism answers to `admin` / `archipelago`.
It is out of scope here (this plan is the gateway migration) and was not touched. It wants its own
requirement and plan, and probably the same treatment: a `generated_secrets` entry plus a denylist
entry for the shipped value.
## Deviations from Plan
### Bcrypt generation had to be factored out first
**Found during:** Task 1
**Issue:** The plan says rotation should "generate a replacement pair through the same helper
`ensure_gateway_credential` uses". 01-11 never actually created such a helper — it left the bcrypt
arm inline in `ensure_one` and had `ensure_gateway_credential` call `ensure_one`. Rotation cannot
call `ensure_gateway_credential`, because `ensure_one`'s idempotent fast path returns early when the
target files are present and non-empty, which is precisely the state rotation acts on.
**Resolution:** Extracted `write_bcrypt_pair(dir, name)` from the `Bcrypt` arm; `ensure_one` and
rotation both call it. Still exactly one generation implementation, which is what the instruction was
protecting.
**Files modified:** `core/archipelago/src/container/secrets.rs`
## Known Stubs
None.
## Threat Flags
- **T-01-72 (critical, EoP)** — mitigated in code, **not yet proven on a node**. Task 2 step 6 (old
credential rejected, new one accepted) is the proof and has not been run.
- **T-01-73 (DoS, rotation loop)** — mitigated and unit-tested: the rotated value is not on the
denylist, so the next tick is a no-op (`rotation_is_idempotent`).
- **T-01-74 (info disclosure)** — mitigated structurally: `rotate_compromised_gateway_credential`
returns `bool`, so the credential is not even in scope at the logging call site.
- **T-01-75 (tampering / data loss)** — mitigated: no teardown primitives added (grep-verified), the
recreate goes through `secret_env_hash`. On-node data-survival check is Task 2 step 5, not run.
- **T-01-76 (repudiation — signing off without exercising rotation)** — **live risk, unresolved.**
Whether archi-dev-box is affected or already clean is still unknown; the plan requires declaring
which case it is and deliberately seeding the old value if the node is clean.
- **T-01-77 (operator lockout)** — partially mitigated: the plaintext exists at a named 0600 path and
the log line points at it, but there is no UI retrieval path (see the gap above).
- **T-01-SC** — no crates added.
## Self-Check
- CONFIRMED: `cargo test -p archipelago secrets` → **16 passed, 0 failed** (the `container::secrets`
module holds 14 `#[test]` fns, all six new rotation cases among them:
`rotates_a_denylisted_gateway_credential`, `leaves_a_unique_gateway_credential_alone`,
`leaves_an_unrecognised_credential_alone`, `no_op_when_no_gateway_credential_exists`,
`rotation_is_idempotent`, `rotation_touches_no_other_secret`)
- FOUND: `rotate_compromised_gateway_credential` in `secrets.rs` (definition + 5 test uses)
- FOUND: exactly 1 non-comment reference in `prod_orchestrator.rs`
- CONFIRMED: 0 added teardown primitives (`rm -f` / `remove_dir_all` / `podman rm` / `chown`) in the
`prod_orchestrator.rs` diff
- CONFIRMED: `cargo fmt --check -p archipelago` clean. It was **not** clean before this plan —
`install.rs` carried drift introduced by 01-11's commit (`42652547`), fixed here. That check has
blocked the release gate before (`37d293be`), so it is worth keeping green rather than discovering
at ship time.
- CONFIRMED: `cargo test -p archipelago` (after `cargo clean -p archipelago`) — **1008 passed, 1
failed**. The failure is `container::boot_reconciler::tests::second_pass_fires_after_interval`, the
same wall-clock-timed test (50ms tick) that was flaky during 01-11; re-run in isolation it is
**4 passed / 0 failed in 0.46s**. `boot_reconciler.rs` is untouched by this plan.
- **NOT RUN:** Task 2's eight-step on-node checkpoint, and `tests/lifecycle/run-gate.sh`
### A false alarm worth recording, because it cost an hour
An intermediate full-suite run reported `credentials::operations::tests::test_list_credentials_filter_by_did`
failing with "invalid utf-8 sequence of 1 bytes from index 2" — an identity-credentials test in a
module this plan does not touch, which had passed in the 01-11 run two hours earlier.
Cause: **corrupted build artifacts, not a regression.** Two duplicate `cargo test` runs had been
started against the same workspace lock and one was `SIGTERM`ed to free it. The next compile surfaced
`rust-lld: error: undefined hidden symbol` — precisely the incremental-cache corruption CLAUDE.md
documents. After `cargo clean -p archipelago` the credentials test passes and the only failure is the
known timing flake above.
Lesson for the next executor on this box: do not kill an in-flight `cargo` to free the build lock —
let it finish. A corrupted target dir produces failures in modules you never touched, which reads
exactly like a real regression and is not one.

<objective>
Keep the FIPS/Tor pills forever, and make sure a phone shows them.
Purpose: UIFIX-01 is a BLOCKER with two halves. The user explicitly values these pills ("really
helpful") and asked that no future cleanup remove them — that half is solved by pinning them with a
test, which nothing in the repo does today. The other half is that at mobile widths they are hidden or
cramped, so exactly the users least able to judge their connection cannot see whether a file arrived
over the fast encrypted mesh or over Tor. The planner could not determine which specific render site
fails on a phone, so this plan audits every site rather than guessing at one.
Output: a complete, recorded per-site mobile verdict; a fix at every failing site; and a test that
makes their removal a build failure.

<read_first>
- `neode-ui/src/views/Cloud.vue` lines 280-324 — the peer cards in the Folders tab. The badge row
is `flex items-center gap-2 text-xs` holding the trust pill and, when
`peerTransport(peer.onion)` is known, the transport pill rendering
`FIPS`/`TOR` plus a latency figure, with a `Peer Node` text fallback when it is not known. Note
the row has no wrapping and no responsive treatment at all.
- `neode-ui/src/views/Cloud.vue` lines 199-218 — the Peer Files aggregated list rows. Each row
shows a category icon, filename, size and price, and a peer-name pill — and no transport pill,
even though these rows are files from peers. Decide, and record, whether this is a site that
should carry one: the requirement is about a user seeing a file's transport state.
- `neode-ui/src/views/Cloud.vue` lines 150-178 — the Paid Files rows, for the same decision.
- `neode-ui/src/views/PeerFiles.vue` lines 8-38 — the header. There is a desktop title block
(`hidden md:block`) carrying the pill, and a separate `md:hidden` copy of the pill added
specifically so mobile still sees it. Read the comment above it: someone already fixed one half
of this. Confirm whether that copy actually renders and is legible on a phone today.
- `neode-ui/src/views/PeerFiles.vue` lines 640-676 — `transportPill`, the single source of the
label, colour classes and tooltip for `fips` / `mesh` / `lan` / `tor` / unknown. This is the
canonical mapping; anything this plan adds must use it rather than re-deriving colours.
- `neode-ui/src/views/PeerFiles.vue` lines 152-232 — the per-file card body, which shows an access
badge and action buttons, for the same site decision.
- `neode-ui/src/views/dashboard/__tests__/keepAliveTabs.test.ts` — the house convention for a
structural pin test, and the file the standing rule requires stay green.
</read_first>
<behavior>
- Mounting each surface with a known transport renders the transport pill with its label text.
- Mounting with an unknown transport renders the existing not-known treatment and no pill.
- Removing the pill from any audited site makes the suite fail — that is the whole point of the
test, so write each assertion so it is specific to a site, not satisfied by any pill anywhere.
- The pill's label and colour come from the canonical mapping, not from a duplicated table.
</behavior>
<action>
Start with the audit, because the fix depends on it. Start the dev preview and open each of the
sites listed above at a phone viewport (390×740 is the reference; also check 320×640, the narrowest
the app supports). For each site record: does the pill render at all, is its text fully readable,
does it overlap or push anything, and does it survive a long peer name or a long filename. Put the
result in the SUMMARY as a table with columns: site, file and line, renders on mobile, legible,
action.
Then fix every site the audit marked as failing, and only those. The likely shapes, depending on
what you find: let the badge row wrap (`flex-wrap`) so a pill drops to a second line instead of
overflowing; drop the latency figure from the pill at small widths while keeping the transport word,
since the word is the security-relevant part and the milliseconds are not; or render a compact pill
variant on mobile the way `PeerFiles.vue`'s header already renders a mobile-specific copy. Choose
per site based on what you actually saw, and record why. Do not apply a responsive change to a site
the audit passed — an unnecessary change to a working desktop layout is exactly what the standing
rule forbids.
Settle the two open site questions rather than leaving them: whether the Peer Files aggregated
rows and the Paid Files rows should carry a transport pill. Both list files that came from peers,
and the requirement is about a user seeing a file's transport state — but the aggregated rows show
files from many peers at once, and a per-row pill may be the honest answer or may be noise. Make a
decision, state the reasoning, and if the answer is yes, implement it using the canonical mapping
and add it to the pin test. If the answer is no, record why the existing peer-level pill is
sufficient for those rows.
Write the pin test as you go: one assertion per confirmed render site, each keyed to something that
identifies that site specifically, plus a comment at the top of the file saying in plain words that
these pills are a user-requested permanent feature and that a failure here means someone removed
one, not that the test is stale.
Change nothing else on either view. Desktop rendering must be untouched at every site, including
the ones you fix.

Re-open every site the audit marked as fixed at both 390×740 and 320×640 and confirm the pill now
renders fully and legibly, with a long peer name and a long filename present so the overflow case
is actually exercised — if the mock data has no long names, edit the rendered text in the element
inspector to force it rather than changing the mock backend, and say so.
Then confirm desktop is untouched. Open each changed site at 1440×900 and compare against the
pre-change build. State in the SUMMARY that each changed site renders identically on desktop, or
name what moved and fix it — the standing rule is that the only visual change this phase ships is
the one the user asked for.
Finally, confirm the pin does its job: temporarily delete one pill from one site, run the suite,
and confirm it fails. Restore the pill and confirm the suite passes again. Record both results.
A pin that does not fail when the thing it pins is removed is not a pin.

## Planner Assumptions (flagged, unresolved)
- **The planner could not identify which specific site fails on mobile.** Reading the source showed
`PeerFiles.vue`'s header already carries a mobile-specific pill copy added for exactly this reason,
and `Cloud.vue`'s peer-card badge row has no responsive treatment at all — the latter is the most
likely culprit, but "most likely" is not evidence. Task 1 is therefore an audit that fixes what it
finds, rather than a fix aimed at a guessed target. If the audit finds every site already renders
correctly, that is a legitimate outcome for the mobile half — record it with the evidence, and the
"kept, never removed" half of the requirement is still fully delivered by the pin test.
- **Whether the aggregated Peer Files rows and the Paid Files rows should carry their own pill is a
genuine product question**, not something the planner should decide from a file read. Task 1
requires a stated decision with reasoning either way, so the answer is recorded rather than assumed.
<threat_model>
## Trust Boundaries
| Boundary | Description |
|----------|-------------|
| observed browse transport → security claim shown to the user | The pill is a security signal: it tells the user whether their file moved over the encrypted mesh or over Tor |
| peer-supplied names → rendered alongside the pill | Long or hostile peer names share the row the pill lives in |
## STRIDE Threat Register
| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
|-----------|----------|-----------|----------|-------------|-----------------|
| T-01-78 | Spoofing | a pill claiming a transport that was not actually used, so a user trusts a channel they should not | high | mitigate | The prohibition requires the pill to render only from the recorded browse result; an unknown-transport test case asserts no pill is fabricated, and the canonical mapping is reused rather than duplicated |
| T-01-79 | Information Disclosure | a mobile user unable to see that a file arrived over Tor and acting as though it were the trusted mesh path | high | mitigate | This is the requirement itself; Task 1's audit covers every render site and Task 2 re-checks each fix at the two narrowest supported widths |
| T-01-80 | Tampering | a later cleanup silently deleting the pills again | high | mitigate | The pin test asserts per site, and Task 2 proves the pin actually fails when a pill is removed |
| T-01-81 | Spoofing | a long peer-supplied name pushing the pill off screen so it is effectively absent on mobile | medium | mitigate | Task 2 requires the long-name case to be exercised deliberately at both narrow widths, not just whatever the mock data happens to contain |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs nothing — template class changes and one vitest file. If an implementation choice would add a dependency, stop: RESEARCH.md's Package Legitimacy Audit must cover it first, with a blocking human checkpoint for any `[ASSUMED]`/`[SUS]` entry |

<objective>
Put all six UI fixes in front of a human, on the node, once.
Purpose: each of plans 01-12 through 01-17 verifies itself with tests and a local-preview observation,
which is the right granularity for an autonomous plan but is not sufficient evidence for a
user-reported blocker. Two of these fixes — picture-in-picture surviving a tab change, and the pills
at phone width — are about device behaviour that a desktop preview cannot reproduce. Rather than
interrupting five plans with five checkpoints, they are gathered here so the operator is asked once,
after the code is on archi-dev-box. This mirrors how plan 01-10 consolidates the federation and
Lightning sign-offs.
Output: a recorded sign-off, or a numbered issue list that becomes the input to a gap-closure pass.

Build the frontend and deploy it to archi-dev-box with the dev-pair frontend-only path. Record the
exact command in the SUMMARY.
Do not use the Tailscale or alpha-tester paths, do not cut a release, do not touch the OTA manifest,
and do not deploy to any fleet node. Note that this plan set's FED-07 work is backend and is
verified separately by plan 01-16 — this deploy is frontend only.
Check whether archy-x250-dev is reachable. It has been offline since phase 2. If it is still
offline, record that plainly as a gap rather than waiting for it or pretending the pair was
covered; single-node verification on archi-dev-box with the second-node gap recorded honestly is
the expected pattern for this phase.
Then confirm the node is actually serving this build before handing over to the checkpoint — fetch
the served bundle from archi-dev-box and grep it for strings this plan set introduced (the
onboarding cue copy, the picture-in-picture handoff class, and the paid-item viewer). Grep the
served asset, not the local `web/dist` copy: per CLAUDE.md the frontend build can silently no-op,
and a checkpoint run against a stale bundle is worse than no checkpoint.

<name>Task 2: Six-fix sign-off on archi-dev-box</name>
<what-built>
Six user-reported UI issues, now on archi-dev-box:
- **Connected nodes (UIFIX-02).** On the Web5 tab, the connected-nodes card no longer grows to fit
every node. Its height now comes from the card beside it in the row and the list scrolls inside
that height, with a floor so a short neighbour cannot squash it. Below the two-column breakpoint
nothing changed.
- **Onboarding tickbox (UIFIX-03).** On a screen too short to show the whole seed step, a soft
gradient and a small glass pill reading "One more step below" now appear at the bottom edge of
the scrolling area. Clicking it scrolls the confirmation tickbox into view, and it disappears
once the tickbox is visible. On a tall screen it never appears at all.
- **Paid Files pictures (UIFIX-04).** Purchased pictures and videos now open in the app's own
lightbox instead of a browser tab. Purchased music still goes to the bottom-bar player, and
purchased documents still open the way they did.
- **Loader states (UIFIX-06).** Opening a purchased file now shows a spinner and an "Opening…"
label on its row for as long as the fetch takes, and a failure now shows an error instead of
appearing to do nothing. Every other surface that was flagged as slow was audited and its verdict
recorded.
- **Picture-in-picture (UIFIX-05).** Entering picture-in-picture now closes the lightbox with a
handoff animation, and the video keeps playing. The session survives switching main tabs and
survives buffering pauses; only explicitly stopping it ends it.
- **FIPS/Tor pills (UIFIX-01).** The pills are now pinned by a test so no future cleanup can remove
them, and every site that could not be read at phone width was fixed.
</what-built>
<how-to-verify>
Run all of this against archi-dev-box's own UI, not the local preview. Use a real phone or the
browser's device emulation for the narrow checks, and say which you used.
1. **Connected nodes scroll (UIFIX-02).** Open the Web5 tab on a wide window. Expected: the
connected-nodes card and the card to its right are the same height, and if there are more nodes
than fit, the list scrolls inside the card — the row does not get taller. Switch between the
trusted, observers and requests tabs: expected the card's height does not change. Then narrow the
window to a single column: expected exactly the layout you had before this change.
2. **Onboarding cue (UIFIX-03).** Open the onboarding seed step at a short viewport (a small laptop
height, or device emulation at roughly 1280×620). Expected: a soft fade and a small pill reading
"One more step below" at the bottom of the scrolling area; clicking it brings the tickbox into
view and the cue disappears. Confirm the cue does not tick the box for you and the Continue
button stays disabled until you tick it yourself. Then open the same step at full height:
expected no cue at all and a step that looks exactly as it did before.
3. **Paid Files in the lightbox (UIFIX-04) and the loader (UIFIX-06).** Go to Cloud → Paid Files
and click a purchased picture. Expected: the row shows a spinner and "Opening…" while it loads,
then the picture opens in the app's lightbox — no new browser tab. Click a purchased video:
expected the same, in the lightbox with player controls. Click a purchased music track: expected
the bottom-bar player, not the lightbox. If you can, click one twice quickly: expected one load,
not two.
4. **Picture-in-picture (UIFIX-05).** Open a video in the lightbox and click the
picture-in-picture button. Expected: the lightbox animates away in a way that reads as the video
moving into the small window rather than the lightbox being dismissed, and the video keeps
playing. Now switch between main tabs a few times: expected playback continues. Now cause a
buffering pause — throttle the network in devtools, or seek far ahead: expected it recovers and
the small window stays. Now close the small window explicitly: expected playback stops and
nothing is left behind. Finally open the lightbox again and close it with the close button and
with Escape: expected exactly the close animation it had before.
5. **FIPS/Tor pills at phone width (UIFIX-01).** At a phone width, go to Cloud and look at the peer
cards, then open a peer's files. Expected: wherever a FIPS or Tor pill appears on desktop it
appears here too, fully readable, not clipped and not overlapping anything, including when a peer
name or filename is long. Compare the same screens at desktop width: expected unchanged.
6. **Nothing else moved.** Move through the main tabs and the Cloud sub-tabs. Expected: the page
margins, the slide transitions between tabs, and every existing animation look exactly as they
did before this plan set. Phase 2 broke margins and slide transitions this way once, so this is a
real check, not a formality.
If anything fails, say which numbered step and what you saw — that becomes the gap list rather than
a re-run of the whole plan set.

## Planner Assumptions (flagged, unresolved)
- **archy-x250-dev is assumed to still be offline.** Phase 2 checked three times and found it gone.
Task 1 re-checks rather than assuming, and records the gap either way; nothing in this plan blocks on
it.
- **Whether archi-dev-box has purchased content to test step 3 with** is unknown to the planner. If it
has none, say so in the sign-off rather than marking step 3 passed on the demo — a demo-only pass for
a paid-content path is exactly the divergence class this phase exists to remove.

| T-01-82 | Elevation of Privilege | a verification deploy reaching fleet or alpha-tester nodes | high | mitigate | Task 1 requires the frontend-only dev-pair path, forbids the Tailscale and alpha-tester flags and any release or OTA path, and requires the exact command and host list to be recorded for audit |
| T-01-83 | Repudiation | signing off against a stale bundle the node never actually received | high | mitigate | Task 1 requires grepping the bundle served by the node — not the local build output — for three strings this plan set introduced, before the checkpoint runs |
| T-01-84 | Information Disclosure | a screenshot or recording of the verification exposing a recovery seed from step 2 | high | mitigate | Step 2 exercises the onboarding step's layout only; the operator is not asked to capture or transcribe the words, and nothing in this plan asks for an image of that screen |
| T-01-85 | Repudiation | a demo-only pass on the paid-content path being recorded as a node pass | medium | mitigate | The prohibition forbids local-preview evidence for node-named checks, and the planner assumption requires saying so explicitly if the node has no purchased content |
| T-01-SC | Tampering | npm/pip/cargo installs | high | mitigate | This plan installs nothing and modifies no source file — it builds, deploys and asks. If a fix arising from the checkpoint needs a dependency, it belongs in a gap-closure plan whose research covers the Package Legitimacy Gate first |

<objective>
Fix Lightning receive on nodes whose channels are private/unannounced.
`handle_lnd_createinvoice` posts to LND's REST `/v1/invoices` with only `value`
and `memo`. LND defaults `private` to `false`, so the returned invoice carries
`route_hints: []`. Private channels are not propagated through public gossip, so
a sender has no way to find a route — the invoice is unpayable by anyone.
Diagnosed on `archy-x250-mad2` (2026-07-31), whose single channel to "Olympus by
ZEUS" is `private: true` with ~40.8k sats of usable inbound. Three wallet-UI
invoices (10,000 / 5,000 / 500 sats) all had empty route hints and never received
an HTLC. The one invoice that DID settle carries a memo ("Paid to Archipelago
(Order ID: ...)") that appears nowhere in this Rust source — it came from a
separate system (likely BTCPay) that builds invoices correctly. That is why
"some payments have worked" while the wallet's own Receive flow never has.
**This is not node-specific.** The bug is unconditional; it only *manifests*
where a node lacks a public channel. Any user relying on a private channel has a
broken Receive flow today.

Add `"private": true` to `invoice_body` in `handle_lnd_createinvoice` so LND
embeds hop hints for unannounced channels:

"memo": memo,
"private": true,
});
```
Setting it unconditionally is correct and safe: a route hint is harmless when
the node also has public channels — LND still routes directly over a public
channel when it can, and the hint merely offers an alternate path. Add a
short comment stating why it is unconditional, so a future reader doesn't
"optimize" it back to conditional and silently reintroduce the bug.
Then audit every OTHER invoice-creation call site for the same omission —
grep the tree for `/v1/invoices`, `addinvoice`, hold-invoice, LNURL and any
keysend-adjacent flow. Fix each that should carry route hints; for any that
deliberately should not, record the reason in the SUMMARY. Report the full

2. On a node under our control with only PUBLIC channels, creating and paying
an invoice still behaves exactly as before — no regression. Note the
limitation honestly: a public-channel node shows empty route hints even
when the fix is correct, so this checks non-regression only.
Post-OTA-release, performed by the device owner:
3. Create an invoice through the **wallet UI** (not raw `lncli`) — e.g. 100 sats.
4. `lncli decodepayreq <invoice>` → `route_hints` populated with the Olympus
channel's `chan_id` (was `[]` before this fix).

# Phase 1 Plan 19: Invoices Embed Route Hints for Private Channels (FED-08) Summary
**A node whose inbound liquidity sits on unannounced channels could not be paid: its invoices carried no route hints, so a payer had no way to discover a path in. Both invoice-creation paths now mint their body through one constructor that sets `private: true` unconditionally.**
## Performance
- **Duration:** ~20 min (code committed 2026-07-31 as `e5c38866`; this SUMMARY 2026-08-02)
- **Tasks:** 1/2 (Task 2 is a post-OTA checkpoint on a user device — see below)
- **Files modified:** 1
## Accomplishments
- `build_invoice_request_body(amount_sats, memo)` is now the single place an LND `/v1/invoices` body is constructed, with `private: true` set unconditionally and a doc comment explaining why it must stay that way.
- Both call sites use it: the seller-side/peer-file flow (`create_invoice`) and the wallet UI's Receive flow (`handle_lnd_createinvoice`, the `lnd.createinvoice` RPC). The duplicated `json!` literal that let one site diverge from the other is gone.
- `invoice_request_body_always_sets_private_true` pins the field for both sites at once.
## Deviations from Plan
None.
**Process note:** as with 01-20, the code landed on 2026-07-31 (`e5c38866`) but no SUMMARY was written and the roadmap entry was never ticked, so the plan read as unstarted. This file closes that gap.
## Known Stubs
None.
## Threat Flags
None. `private: true` does not weaken anything: it adds a routing hint to an invoice the payer already holds. It does reveal the existence of an unannounced channel to whoever holds that specific invoice — which is inherent to being payable over that channel at all, and is the explicit intent of the requirement.
## Outstanding: post-OTA checkpoint (Task 2)
The affected node is **archy-x250-mad2, a user's device**. Commit `516c3bfa` records the standing
constraint: never deploy directly to a user device — verify post-OTA instead. So the remaining
verification is:
1. Ship the release
2. After it lands on the affected node, mint an invoice from the wallet's Receive flow
3. Confirm the BOLT11 decodes with a route hint (`r` field) for the private channel
4. Confirm a payment from outside actually settles over it
This is the one piece of FED-08 that cannot be proven from here.

---
<objective>
Mesh sends fail entirely on affected nodes because both transports are down, and
the second failure is self-inflicted.
Diagnosed 2026-07-31 on a live node:
1. The FIPS direct transport (Yggdrasil-style `fd..` IPv6) times out with
`connect_fail` for peers other than the currently-connected tree peers, so
every send falls back to Tor.
2. The Tor fallback then fails with `No more HSDir available to query` — Tor
cannot resolve any peer `.onion` address.
Root cause of (2): **the container doctor restarts Tor every ~5 minutes,
forever.** `fix_tor_permissions()` in `scripts/container-doctor.sh` treats any
mode other than the literal string `700` as broken:
```sh
perms=$(stat -c '%a' "$dir")
if [ "$perms" != "700" ]; then
chmod 700 "$dir"; fixed=true
fi
...
if $fixed; then systemctl restart tor@default; fi
```
Tor sets its own `HiddenServiceDir` to **2700** (setgid). So every run the doctor
sees `2700 != 700`, "fixes" it, and restarts Tor; Tor comes back up and sets 2700
again; the timer fires 5 minutes later and the cycle repeats. Observed restarts
on the node: 13:07:56 → 13:13:14 → 13:18:39 → 13:23:57, each within a second of
an `archipelago-doctor.timer` firing. Tor never survives long enough to build a
usable consensus/HSDir cache, so onion lookups fail and the mesh's only remaining
transport dies with it.
`2700` is not a defect — the setgid bit is harmless here and group/other access
is still fully denied, which is the property that actually matters.
**Scope note:** this plan fixes the restart loop only. The FIPS direct-transport
`connect_fail` (problem 1) is a separate concern and belongs with FED-03's
structured review of the transport/dial layer — record it there, do not attempt
both here.

- `image-recipe/configs/archipelago-doctor.timer` — `OnUnitActiveSec=5min`, `RandomizedDelaySec=60`: this is the loop's clock
- `core/archipelago/src/bootstrap.rs:24-31` — the script is embedded via `include_str!` and written to `/home/archipelago/archy/scripts/container-doctor.sh` on every boot, so nodes pick the fix up through the normal binary release
</read_first>
<action>
Correct the permission predicate so it tests the property that matters —
group and other have no access — instead of exact-matching one octal string.
Compare the low three digits of `stat -c '%a'` (which omits leading zeros, so
handle both `700` and `2700` forms), and treat the directory as correct when
those are `700`. Only a genuinely permissive mode (any group or other bit
set, e.g. `750`, `707`, `2755`) is a real defect worth fixing.
Keep correcting real defects, and keep restarting Tor when a real fix is
applied — but add a **restart backoff** so a restart storm is impossible even
if some future condition makes the fix fire repeatedly: record the last
restart time (e.g. a timestamp file under `/var/lib/archipelago/`) and skip
the restart if one happened within the last 30 minutes, logging that it was
skipped. The current defect is being fixed at the predicate, but the backoff
is what makes the class of failure non-recurring.
Log clearly in both directions — when a directory is accepted as already
correct (at debug level, so a healthy node stays quiet) and when a real fix
is applied. The original bug was invisible precisely because "Fixed
permissions on ... (2700 -> 700)" looked like the doctor working correctly.

The doctor no longer mistakes Tor's setgid `2700` hidden-service directory for

minutes. A restart backoff makes a restart storm impossible even if some other
condition triggers the fix repeatedly.

On an affected node, after the release lands:
1. `systemctl status tor@default` — note the uptime. Wait 15 minutes (three
doctor intervals) and check again: uptime should keep growing, with no
restart. Before the fix it reset roughly every 5 minutes.
2. `journalctl -u archipelago-doctor -n 50` — no recurring
"Fixed permissions on ... hidden_service_* (2700 -> 700)" lines.
3. Once Tor has been up ~20-30 minutes, confirm onion resolution works: a
mesh send to a peer reachable only via Tor should succeed, and the logs
should no longer show `No more HSDir available to query`.
4. Confirm the doctor still does its job: temporarily `chmod 750` a
hidden-service directory, wait for the next doctor run, and check it is
corrected back to deny group/other access.

- `bash -n` passes; the 2700 case is accepted and the 750/707 cases are still fixed
- On an affected node, Tor uptime exceeds the doctor's interval and onion resolution recovers

<success_criteria>
- Tor is no longer restarted every ~5 minutes by the doctor
- Tor keeps its consensus/HSDir cache, so `.onion` peers resolve and the mesh Tor fallback works again

# Phase 1 Plan 20: Stop the Doctor Fighting Tor Over the Setgid Bit (FED-09) Summary
**The container doctor treated Tor's own `2700` hidden-service directory as a permission defect, "fixed" it, and restarted Tor — every five minutes, forever. Tor never lived long enough to build a usable HSDir cache, so onion lookups failed and the mesh's Tor fallback died with it.**
## Performance
- **Duration:** ~30 min (code committed 2026-07-31 as `4435f95e`; verification and this SUMMARY 2026-08-02)
- **Tasks:** 1/2 (Task 2 is a post-OTA checkpoint — see below)
- **Files modified:** 1
## Accomplishments
- The predicate now compares the low three digits of `stat -c '%a'`, so Tor's setgid `2700` and a plain `700` both read as correct, while `750`, `707` and `2755` are still corrected. Verified directly against all five modes.
- A 30-minute restart backoff (`/var/lib/archipelago/doctor-tor-last-restart`) makes a restart storm impossible even if some future condition makes the fix fire repeatedly. The predicate fixes today's bug; the backoff retires the class.
- The "already correct" branch logs at debug level so a healthy node stays quiet — the original defect hid inside a log line that read like success.
## Evidence on a real node (archi-dev-box, 2026-08-02)
- `tor@default` active since **2026-08-01 15:25:45** — over 15 hours continuous, spanning roughly 180 doctor intervals. Before the fix, observed restarts were 13:07:56 → 13:13:14 → 13:18:39 → 13:23:57, each within a second of a timer firing.
- **Zero** `Fixed permissions … hidden_service` lines across **542** doctor log entries in the preceding 6 hours.
## Deviations from Plan
None. The implementation matches the plan's action exactly: predicate corrected at the property level, backoff added, logging made quiet-when-healthy.
**Process note:** the code landed on 2026-07-31 as `4435f95e` but no SUMMARY was written and the roadmap entry was never ticked, so the plan looked unstarted for two days. That is the bookkeeping gap this file closes.
## Known Stubs
None.
## Threat Flags
- The plan's prohibition — never loosen hidden-service permissions — holds: group and other access is still denied on every path. `2700` is accepted precisely *because* it denies them; the setgid bit is orthogonal to that property.
- **Scope boundary respected:** the FIPS direct-transport `connect_fail` (problem 1 in the diagnosis) was deliberately NOT touched here. It belongs with FED-03's structured review of the transport/dial layer.
## Outstanding: post-OTA checkpoint (Task 2)
Task 2 verifies on an **affected** node after the release lands, and explicitly forbids deploying
directly to a user's device (`archy-x250-mad2` or any node that is not ours) — verification is
post-OTA only. Remaining there:
1. Tor uptime keeps growing across three doctor intervals (met on archi-dev-box; needs repeating on an affected node)
2. No recurring "Fixed permissions" lines (met on archi-dev-box)
3. Onion resolution works — a mesh send to a Tor-only peer succeeds and `No more HSDir available to query` is gone
4. The doctor still corrects a deliberately `chmod 750`'d hidden-service directory
Items 3 and 4 are the ones genuinely outstanding; 1 and 2 already have real-node evidence.

# Phase 1 Context — Federation & Mesh Hardening
**Source:** User decisions captured in conversation 2026-07-29 (no full discuss-phase run)
<domain>
Federation/fleet + mesh hardening on a live OTA fleet, plus two lightning-adjacent UI features
(channel-open UX, on-brand paid-tick animation). Backend: Rust workspace at core/. Frontend:
neode-ui (Vue), dev preview :8100 against archi-dev.
</domain>
<decisions>
- **FED-05 "public nodes" scope (LOCKED, user 2026-07-29, corrected same day):** the
public/other list in the channel-open picker = MESHED PEER NODES THAT HAVE LIGHTNING
INSTALLED — nodes known over the mesh (mesh peers/contacts beyond bilateral federation
trust) that advertise lightning capability. NOT lnd listpeers, NOT a curated list, NOT
a live LN-graph query. Implies peers need to advertise a "lightning installed/available"
capability (plus their URI/pubkey) over mesh/federation state so the picker can list
them. Manual URI paste can remain as a fallback entry path. Primary lists: (1) trusted
federated nodes by hostname, (2) meshed peers with lightning installed — "request to
open a channel with" these.
- **FED-05 URI sharing default (Claude's discretion, revisable):** a federated peer's
Lightning URI/pubkey rides the federation sync payload by default — federation trust is
already bilateral and explicit. Follow the existing shared-field pattern in
NodeStateSnapshot; if an opt-in toggle already exists for similar fields (e.g.
shared_location), mirror that pattern with default ON for lightning URI.
- **FED-06 (LOCKED, user):** paid-tick circle = ScreensaverRing.vue style (EQ segments),
applied consistently to every paid/success tick surface (SendBitcoinModal success pane,
WalletScanModal success-ring).
- **FED-04:** demo attachment parity core already shipped on main (c2ce71c6) — remaining
scope is the leftover mock gaps found in research (contacts-list/save, reaction/reply/
edit/delete/forward stubs that never mutate demo state).
- **Priority framing (user):** federation removal/sync correctness is the reason this phase
exists — "we should just be working on making that as tight as possible".
</decisions>
<specifics>
- UI work verified on the :8100 dev preview against archi-dev BEFORE any deploy (user
requirement, applies to FED-05/FED-06).
- Deploy discipline per CLAUDE.md: dev pair before OTA; commit+push every unit of work.
- Modals must Teleport to body (repeated user complaint — see project feedback memory).
</specifics>
<deferred>
- Live Lightning-graph search of arbitrary public nodes (not connected peers) — out of
scope for FED-05 v1.
- Curated/shipped public-node directory — not wanted.
</deferred>
<scope_fence>
Do not touch federation trust/join cryptography beyond what removal/sync correctness
requires (STATE.md blocker: tombstone fix touches trust code — re-verify with
tests/multinode/smoke.sh, don't patch blind). No data-destroying migrations.

## Pattern Assignments
### `core/archipelago/src/federation/storage.rs` (locking fix)
**Analog:** `core/archipelago/src/update.rs:35` (`UPDATE_OP_LOCK`)
**Core pattern** (lines 25-35, `update.rs`):
```rust
/// Serializes the mutating update operations (download, apply, and the
/// staging wipe in cancel). The .198 v1.7.103 bricking (2026-07-18) was
/// exactly this race: two concurrent `update.download` RPCs shared one
/// staging file, a cancel wiped staging mid-flight, a third download began
/// re-filling it, and `apply_update` mv'd the 3-second-old 17MB partial of
/// a 49MB binary into /usr/local/bin → SEGV boot loop. Writers take this
/// via `try_lock` so a concurrent caller gets an explicit "already running"
/// error instead of silently interleaving.
static UPDATE_OP_LOCK: tokio::sync::Mutex<()> = tokio::sync::Mutex::const_new(());
```
This is the closest documented precedent in the codebase for "two async
call sites race on the same on-disk resource, fix with a static
`tokio::sync::Mutex::const_new(())`" — same shape of bug as Pitfall 1 in
RESEARCH.md, already root-caused and fixed once before. Copy the doc-comment
style (explain *why*, cite the historical incident) and the `try_lock`
vs. `.lock().await` decision: prefer plain `.lock().await` (blocking wait,
not `try_lock`-reject) for the federation case, since federation writes are
infrequent and a caller silently failing "already syncing" would reintroduce
the original bug's symptom (lost writes) rather than fix it — unlike
`update.rs`'s deliberate reject-on-contention UX.
**Secondary reference:** `core/archipelago/src/container/app_ops.rs:17-24` — a
`HashMap<String, Arc<tokio::sync::Mutex<()>>>` keyed per-app-id, for when a
single global lock is too coarse. Not needed here (one `data_dir` = one
federation store = one lock is fine), but note this pattern exists if the
planner decides per-node-id granularity is warranted.
**Also apply:** `federation::storage::save_nodes` is a direct `fs::write()`,
not atomic temp+rename. No existing atomic-write helper was found elsewhere
in `core/archipelago/src/` (grepped, none present) — this will be genuinely
new code; keep it minimal (`fs::write` to `nodes.json.tmp` then `fs::rename`).
---
### `core/archipelago/src/server.rs` (two federation sync loops, ~L497 / ~L840)
**Analog:** itself (the Tor-refresh loop pattern immediately above, ~L479) and `mesh/listener/session.rs:386`'s `PORT_OPEN_LOCK` for how a shared static lock is threaded through an async loop body.
**Loop skeleton pattern** (both existing loops share this shape — `server.rs:497-515` and `server.rs:840-853`):
```rust
tokio::spawn(async move {
tokio::time::sleep(Duration::from_secs(20)).await; // startup settle delay
let mut interval = tokio::time::interval(Duration::from_secs(90));
// 1800s loop additionally sets:
// interval.set_missed_tick_behavior(tokio::time::MissedTickBehavior::Delay);
loop {
interval.tick().await;
let nodes = match crate::federation::load_nodes(&data_dir).await {
Ok(n) if !n.is_empty() => n,
_ => continue,
};
// ... snapshot local identity, iterate `nodes`, call sync_with_peer ...
}
});
```
**Error handling pattern:** both loops only `debug!()` on failure (RESEARCH.md
Anti-Pattern flagged this — FED-02 requires operator-visible errors). Do not
copy this part; extend to persist `last_sync_error` on the node record
(mirrors how `record_peer_transport` already persists `last_transport`/
`last_transport_at` in `federation/storage.rs:120-147` — same "write a
result field back to the node struct after each attempt" shape, just for the
error side instead of the success side).
**If collapsing the two loops:** the 1800s loop's unique tail call is
`refresh_federation_mesh_peers()` (per RESEARCH.md Open Question 1) — move
that single call to the end of the 90s loop's per-pass completion rather
than deleting the loop body wholesale, preserving whatever roster-propagation
behavior it provides.
---
### `core/archipelago/src/federation/types.rs` (NodeStateSnapshot Lightning fields)
**Analog:** itself — the existing `shared_location` (`lat`/`lon`) opt-in field on the same struct (lines 124-131).
**Exact pattern to mirror** (`federation/types.rs:124-131`):
```rust
/// This node's own location, for the Mesh Map — only present when the
/// sender has opted in via `server.set-location`'s `share` flag. Absent
/// (not just null) for nodes that haven't opted in, so older receivers
/// and the map's "no location shared" state both fall out naturally.
#[serde(default)]
pub lat: Option<f64>,
#[serde(default)]
pub lon: Option<f64>,
```
Add `lightning_uri: Option<String>` (or `lightning_pubkey` + `lightning_host`
split, matching `FederationPeerHint`'s `pubkey`/`onion` split style at
line 137-145) with the same `#[serde(default)]` back-compat annotation and a
doc comment explaining the opt-in gating (per CONTEXT.md's locked decision:
default ON for federation, unlike `shared_location`'s default-off — call
this out explicitly in the doc comment since it deviates from the analog).
**Gating call site analog** (`api/rpc/federation/handlers.rs:476-479`):
```rust
let shared_location = if data.server_info.share_location {
data.server_info.lat.zip(data.server_info.lon)
} else {
None
};
```
Mirror this shape for the Lightning URI gate, then thread it through
`federation::build_local_state(...)` the same way `shared_location` is
threaded (`sync.rs:230,258-259` — accepted as a parameter, mapped into the
snapshot fields at construction time). If FED-05 lands the "default ON"
decision, this becomes a simpler unconditional read (no `if`), but keep the
struct-level `Option` + `#[serde(default)]` regardless so a future opt-out
setting is a pure additive change.
---
### `core/archipelago/src/api/rpc/lnd/info.rs` (own-node Lightning URI RPC)
**Analog:** `core/archipelago/src/api/rpc/lnd/channels.rs::handle_lnd_openchannel` (`channels.rs:238-336`) for response/validation style in the same file family — reuse verbatim, do not modify; new code only needs to *read* `identity_pubkey`/`uris` out of the same LND REST response `handle_lnd_getinfo` already fetches but doesn't forward. Read `info.rs`'s current struct/response shape directly before editing (not excerpted here — small, single-file change, one Read call is enough at implementation time).
**Dispatcher registration analog** (`api/rpc/dispatcher.rs:125,128`):
```rust
"lnd.getinfo" => self.handle_lnd_getinfo().await,
...
"lnd.openchannel" => self.handle_lnd_openchannel(params).await,
```
Any new RPC (e.g. a dedicated `lnd.own-uri` if the planner decides not to
extend `getinfo`) follows this exact one-line match-arm registration
convention — no separate route table, no middleware wiring beyond this.
---
### `core/archipelago/src/api/rpc/mesh/typed_messages.rs` (mesh capability advertisement / channel-open-request message type)
**No direct analog exists** — RESEARCH.md confirms this is greenfield (no
capability-advertisement field on mesh peers/contacts today). Closest
structural analogs for *how to add a new field to a broadcast peer struct*
and *how to add a new mesh message type*:
**Analog A — read/return handler shape** (`typed_messages.rs:1215-1234`,
`handle_mesh_contacts_list`):
```rust
pub(in crate::api::rpc) async fn handle_mesh_contacts_list(
&self,
_params: Option<serde_json::Value>,
) -> Result<serde_json::Value> {
let service = self.mesh_service.read().await;
let svc = service
.as_ref()
.ok_or_else(|| anyhow::anyhow!("Mesh service not running"))?;
let state = svc.shared_state();
let contacts = state.contacts.read().await;
let peer_vec: Vec<_> = state.peers.read().await.values().cloned().collect();
// ... merge/collapse logic ...
}
```
Use this shape (`mesh_service.read().await` → `shared_state()` →
`.read().await` on the relevant map) for any new "list peers with lightning
capability" RPC.
**Analog B — event-driven send handlers** (`typed_messages.rs:637-976`,
reaction/reply/receipt/forward family) — mirror for a new
"channel-open-request" mesh message type: same struct-per-message-type,
serialize-and-broadcast pattern already used for reactions/replies.
**Security note (carries from RESEARCH.md V4):** any new RPC meant to be
peer-reachable (not just locally-authenticated) must be added to
`is_peer_allowed_path()` (`server.rs:1270`) explicitly — don't assume it
inherits reachability.
---
### `neode-ui/mock-backend.js` (contacts-list/save + stateful reaction/reply/edit/delete/forward)
**Analog — stateful mutation pattern** (`mock-backend.js:4355-4370`,
`mesh.send-content-inline`):
```javascript
case 'mesh.send-content-inline': {
// ... validate params ...
const meshStore = currentStore().mesh
const id = 100 + meshStore.dynamic.length
meshStore.dynamic.push({
// ... message shape matching real daemon's mesh message schema ...
})
return res.json({ result: { ... } })
}
```
**Analog — "mirror the daemon, cite the source" comment convention**
(`mock-backend.js:4312-4317`, immediately above `mesh.transport-advice`):
```javascript
// Mirrors the real daemon's size-based tier logic
// (typed_messages.rs handle_mesh_transport_advice) so the demo shows the
// SAME modals a real node would — the chooser only appears in the narrow
// fits-both band, never unconditionally.
```
Apply both patterns verbatim to the FED-04 gaps:
- `mesh.contacts-list`/`mesh.contacts-save` — currently **absent** (404s),
add cases that read/write a per-session contacts bucket the same way
`meshStore.dynamic` is a per-session bucket (`currentStore().mesh`), citing
`typed_messages.rs:1180-1371` as source of truth per the comment convention.
- `mesh.send-reaction`/`send-reply`/`edit-message`/`delete-message`/
`forward-message` — currently bare `{ok:true}` acks
(`mock-backend.js:4479-4490`, cited verbatim in RESEARCH.md) — replace each
with a `meshStore.dynamic` mutation (find message by id, mutate reactions
array / set edited text / mark deleted / push a forwarded copy), citing
`typed_messages.rs:637-976` (reply/reaction) and `:1065-1180` (edit/delete)
as source of truth.
---
### `neode-ui/src/components/LightningChannelModal.vue` (NEW, FED-05)
**Analog 1 — modal shell:** `neode-ui/src/components/BaseModal.vue:1-40`
```vue
<Teleport to="body">
<Transition name="modal">
<div v-if="show" class="fixed inset-0 flex items-center justify-center p-4" @click.self="close">
<div class="absolute inset-0 bg-black/60 backdrop-blur-md"></div>
<div class="glass-card p-6 w-full relative z-10 flex flex-col" role="dialog" aria-modal="true" @click.stop>
<div class="flex items-start justify-between gap-4 mb-4 shrink-0">
<h3 class="text-xl font-semibold text-white">{{ title }}</h3>
<button @click="close" aria-label="Close">...</button>
</div>
<div v-if="$slots.header" class="shrink-0"><slot name="header" /></div>
<div class="flex-1 min-h-0 overflow-y-auto">...</div>
```
Hard rule per CONTEXT.md/UI-SPEC.md: every new modal MUST use `BaseModal.vue`
or replicate this exact `Teleport` + `fixed inset-0` + `@click.self="close"`
structure — never nest inside a `transform`-affected ancestor.
**Analog 2 — manual URI form + error/startup-notice treatment:**
`neode-ui/src/components/LightningChannelsPanel.vue`
```vue
<!-- line 258-261 -->
placeholder="pubkey@host:port"
<p class="text-white/40 text-xs mt-1">Format: pubkey@host:port</p>
```
```vue
<!-- line 329-336 -->
<div v-if="openError" :class="isStartupNotice(openError) ? amberClasses : 'alert-error'">
<span v-if="isStartupNotice(openError)" class="mr-1">⏳</span>{{ openError }}
</div>
```
```js
// line 599-624 (validation-before-RPC pattern)
if (!uri) { openError.value = 'Peer URI is required'; return }
if (openForm.value.amount < 20000) { openError.value = 'Minimum 20,000 sats'; return }
```
Copy this validate-before-RPC-call, `openError` ref, `isStartupNotice()`
amber-vs-red distinction pattern verbatim into the new modal's "Paste URI
Manually" fallback path.
**Analog 3 — request flow (meshed peer "Request Channel"):**
`neode-ui/src/components/federation/PeerRequestModal.vue`
```vue
<!-- line 34-37 -->
<button :disabled="sending" @click="$emit('send', message.trim() || undefined)">
{{ sending ? 'Sending…' : 'Send Request' }}
</button>
```
Per UI-SPEC.md's Copywriting Contract, reuse this component's pattern
directly (optional message field, `sending`/`Sending…` busy state,
`$emit('send', ...)` / `$emit('cancel')` contract) rather than building a new
request-modal component.
**Analog 4 — picker row layout (trusted-nodes / meshed-LN-peers lists):**
`neode-ui/src/views/federation/NodeList.vue`
```vue
<!-- line 56-65 -->
<span v-if="transportBadge(node)" :class="transportBadge(node)!.cls" :title="transportBadge(node)!.title">
{{ transportBadge(node)!.label }}
</span>
<span :class="trustBadgeClass(node.trust_level)">{{ node.trust_level }}</span>
```
```js
// line 158-159
const trustedNodes = computed(() => props.nodes.filter(n => n.trust_level === 'trusted'))
const peerNodes = computed(() => props.nodes.filter(n => n.trust_level !== 'trusted'))
```
Mirror this row layout (name + transport badge + trust/status badge +
action button) for both the trusted-nodes and meshed-LN-peers picker
columns; reuse `transportBadge()`'s FIPS/Tor logic as-is per
`Don't Hand-Roll` in RESEARCH.md (no new transport-tracking needed).
---
### `neode-ui/src/components/ScreensaverRing.vue` (new `badge` size variant)
**Analog:** itself — existing `compact`/`default` size-class pattern (lines 15-66).
```vue
const props = withDefaults(defineProps<{
size?: 'default' | 'compact'
...
}>(), { size: 'default', segmentCount: 48 })
const sizeClass = computed(() => props.size === 'compact' ? 'viz-ring-compact' : 'viz-ring-default')
```
```css
.viz-ring-compact { /* diameter/--viz-radius rules, lines 60-66 incl. breakpoint */ }
```
Add a third `'badge'` union member + `viz-ring-badge` CSS class following the
exact same shape (mobile diameter, `≥768px` breakpoint diameter,
`--viz-radius` custom property), sized per UI-SPEC.md's table (160px/192px,
`--viz-radius` 80px/96px). Also add the missing
`@media (prefers-reduced-motion: reduce) { .viz-segment { animation: none; opacity: 0.6; } }`
guard inside this component (UI-SPEC.md flagged this as a real, currently
absent gap — contrast with `SendBitcoinModal.vue`'s existing `.burst-ring`
reduced-motion guard, which should be the copy source for the exact media
query syntax).
**Composition analog (how to layer center content over the ring):**
`neode-ui/src/components/Screensaver.vue`'s existing
`ScreensaverRing` + `ScreensaverLogo` centered-absolute layering — reuse this
`position: relative` wrapper + `position: absolute; inset: 0` inner-content
pattern for both `SendBitcoinModal.vue`'s `.burst-core` and
`WalletScanModal.vue`'s success-ring inner content.
---
### `neode-ui/src/api/rpc-client.ts` (new method wrappers)
**Analog:** existing `mesh.contacts-list`/`contacts-save` wrappers (lines 804, 813):
```typescript
return this.call({ method: 'mesh.contacts-list', params: {} })
...
return this.call({ method: 'mesh.contacts-save', params })
```
New wrappers (own Lightning URI fetch, channel-open-request send) follow this
exact `this.call({ method: '<namespace>.<verb>', params })` one-liner
convention — no custom fetch/axios logic, no new client class.
## Shared Patterns
### Async static lock for a racy on-disk resource
**Source:** `core/archipelago/src/update.rs:35` (`UPDATE_OP_LOCK`)
**Apply to:** `federation/storage.rs`'s `load_nodes`/`save_nodes`/`remove_node`/`update_node_state` call sites (FED-01/FED-02 core fix)
```rust
static <NAME>_LOCK: tokio::sync::Mutex<()> = tokio::sync::Mutex::const_new(());
// acquire with .lock().await (not try_lock — federation writes should queue, not reject)
```
### Optional opt-in shared field on `NodeStateSnapshot`
**Source:** `core/archipelago/src/federation/types.rs:124-131` (`shared_location`)
**Apply to:** New `lightning_uri`/`lightning_pubkey` field (FED-05)
```rust
#[serde(default)]
pub lat: Option<f64>,
```
### Teleport-to-body modal shell
**Source:** `neode-ui/src/components/BaseModal.vue:1-40`
**Apply to:** All new FED-05 UI (hard rule per CONTEXT.md/UI-SPEC.md)
### Mock backend must mirror real daemon logic, with a comment citing the source file/lines
**Source:** `neode-ui/mock-backend.js:4312-4317` (comment above `mesh.transport-advice`)
**Apply to:** All FED-04 mock-backend.js gap fills (contacts-list/save, reaction/reply/edit/delete/forward)
### One-line RPC dispatcher registration
**Source:** `core/archipelago/src/api/rpc/dispatcher.rs:125,128,349`
**Apply to:** Any new backend RPC method added for FED-05 (own LN URI, channel-open-request)
## No Analog Found
| File | Role | Data Flow | Reason |
|---|---|---|---|
| Mesh peer "has lightning" capability advertisement (new field on mesh peer/contact struct + propagation) | model + event-driven | No existing capability-advertisement mechanism for mesh (as opposed to federation) peers exists in the codebase — RESEARCH.md confirms this is genuinely greenfield. Nearest structural precedent is the read/broadcast handler shapes in `typed_messages.rs` (see Pattern Assignments above), not a field-level analog. Planner should design this as a new optional field on whatever struct already carries mesh peer capability info (check `mesh/mod.rs` peer struct at implementation time), following the same `#[serde(default)] Option<T>` back-compat convention used everywhere else in this codebase. |

# Phase 1: Federation & Mesh Hardening - Research
**Researched:** 2026-07-29
**Domain:** Federation node sync/removal (Rust/Tokio async daemon), mesh RPC parity (Rust + Node.js mock backend), Lightning channel-open UX (Vue 3), on-brand success animation (Vue 3/CSS)
**Confidence:** HIGH (backend federation/mesh code — read directly, git-blamed); MEDIUM (FED-05 Lightning-URI UX — net-new surface, no prior art in repo); HIGH (FED-06 — both source components read directly)
<user_constraints>
## User Constraints (from CONTEXT.md)
No CONTEXT.md exists for this phase (not yet run through `/gsd-discuss-phase`). No locked decisions or discretion areas to honor beyond `REQUIREMENTS.md` and the phase description supplied by the orchestrator. Treat all implementation choices below as recommendations for the planner, not locked decisions — the planner should flag any of these that warrant a user check-in (see `## Assumptions Log`).
</user_constraints>
## Summary
The federation and mesh code is more mature than `CONCERNS.md` suggests — several concerns it lists (tombstone-write-swallowed, DID-join without signature verification) were already fixed in commit `01cbec27` (2026-07-02) and the `handle_federation_peer_joined` signature-verification path respectively. **Do not treat `CONCERNS.md` as current truth for this phase; the structured review (FED-03) must re-verify each claim against the code read in this research before acting on it.**
The real, currently-live bug class behind the user's "nodes reappear / sync issues" reports is almost certainly a **concurrency race on `federation/nodes.json`**: `federation/storage.rs` has zero locking (no `Mutex`, no atomic temp-file+rename) around `load_nodes()` → mutate → `save_nodes()`, yet the daemon runs **two independent, overlapping periodic federation-sync loops** (`server.rs` ~line 497, every 90s; `server.rs` ~line 840, every 1800s) plus the manual `federation.sync-state` RPC and `federation.remove-node` RPC — all of which do their own read-modify-write cycle against the same file with no coordination. A `remove_node()` call racing against an in-flight `sync_with_peer()`'s `update_node_state()` (which read the node list *before* the removal landed) will have the sync's stale read clobber the just-written removal when it saves — the removed node reappears with no error, exactly matching the reported symptom, and it is invisible to logs because both loops only `debug!()` on failure. This is the primary hypothesis to design a fix and a regression test around for FED-01/FED-02.
Mesh attachment-send parity (FED-04) was fixed just before this phase started (commit `c2ce71c6`, uncommitted → committed by another concurrent agent during this research session): `mock-backend.js` now implements `mesh.send-content-inline` / `mesh.send-content` / `mesh.fetch-content` / `mesh.transport-advice` mirroring the daemon's real tier logic. What remains for full "rest of the mesh chat surface" parity: `mesh.contacts-list` / `mesh.contacts-save` (peer aliasing, called live from `Mesh.vue` on mount and on rename) are **not implemented in mock-backend.js at all** and will 404 with "Method not found" on the demo; and `mesh.send-reaction` / `send-reply` / `edit-message` / `delete-message` / `forward-message` are stubbed as bare `{ok:true}` acks that never mutate `meshStore.dynamic`, so reactions/edits/deletes silently don't render on the demo even though the RPC call "succeeds."
FED-05 (Lightning channel-open UX) is greenfield: no RPC anywhere in the codebase currently returns this node's own Lightning `identity_pubkey`/`uris` (LND's own `/v1/getinfo` provides both, but `handle_lnd_getinfo` in `core/archipelago/src/api/rpc/lnd/info.rs` doesn't parse or forward them), and `NodeStateSnapshot` (the federation sync payload) carries no Lightning fields for a peer's pubkey/host, so there is no way today to look up a *federated* peer's channel-open target. `handle_lnd_openchannel` (channels.rs) already accepts `pubkey` + optional `address` + `amount`/fee params and does the connect-then-open sequence correctly — reuse it as-is. "Public nodes" browse/request has no existing data source in this codebase (no LN graph query, no curated list) and needs a scope decision from the user before planning task breakdown.
FED-06 is a straightforward swap: `ScreensaverRing.vue` (`compact` size = 240px/320px) renders only the radiating EQ segments (no circle of its own — the "circle" is the separately-layered content in the center, exactly as `Screensaver.vue` does with `ScreensaverLogo`). `SendBitcoinModal.vue`'s `.send-success-burst` is 112px (7rem) with 3 CSS-ripple `.burst-ring` elements plus a `.burst-core` circle+checkmark — swap the `.burst-ring` elements for `<ScreensaverRing size="compact" />`, keep `.burst-core`+checkmark centered on top, and reconcile the size mismatch (ring is 2-3x larger than the current burst container; either scale it down via CSS `transform: scale()` or accept the larger footprint since the modal is `max-w-2xl`). `WalletScanModal.vue` has a second, simpler "paid tick" (`.success-ring`, no ripple animation at all) that the phase's "wherever else the paid tick appears" clause covers — plan to update both.
**Primary recommendation:** Start FED-03's structured review by (1) auditing every `federation::storage` read-modify-write call site for the missing-lock race described above and design a fix (a `tokio::sync::Mutex` per data_dir, or collapsing the two periodic sync loops into one), (2) re-verifying every `CONCERNS.md` federation/mesh claim against current code before acting on it, (3) filling the two demo-parity gaps in `mock-backend.js` (contacts-list/save + stateful reaction/edit/delete), (4) treating FED-05 as new RPC surface (own-node Lightning URI, peer Lightning info propagation, and a scoped "public nodes" answer) before any UI work, and (5) the FED-06 CSS/component swap.
## Architectural Responsibility Map
| Capability | Primary Tier | Secondary Tier | Rationale |
|------------|-------------|----------------|-----------|
| Federation node list, tombstones, sync loops | API / Backend (`core/archipelago/src/federation/`) | — | Disk-persisted state; must be race-free at the storage layer, not patched in the RPC or UI layer |
| Federation removal propagation to mesh chat | API / Backend (`core/archipelago/src/mesh/mod.rs::purge_federation_peer`) | Frontend (Pinia `stores/mesh.ts`) | Backend already purges peer/messages/contacts server-side; frontend must not cache a stale contact after the WebSocket state bump |
| Mesh RPC surface (attachments, reactions, contacts) | API / Backend (`core/archipelago/src/api/rpc/mesh/`) | Dev tooling (`neode-ui/mock-backend.js`) | The demo backend is a parity shim over the same RPC surface — it must mirror backend behavior, never invent its own contract |
| FIPS/Tor transport dial + fallback | API / Backend (`core/archipelago/src/fips/dial.rs`, `transport/`) | — | Transport selection is a backend concern; UI only displays the resulting badge (`last_transport`) |
| Lightning node URI (own + peer) | API / Backend (new: `lnd.getinfo` extension, federation sync payload extension) | Frontend (new modal) | LND is the source of truth for `identity_pubkey`/`uris`; federation sync is the transport for sharing a peer's LN info |
| Channel-open UX (initiate) | Frontend (new modal, `Teleport`-to-body, house style) | API / Backend (`lnd.openchannel` — already exists) | Backend channel-open RPC is complete; only the UI (URI share, trusted-peer picker, public-node browse) is missing |
| Paid-tick success animation | Frontend (`SendBitcoinModal.vue`, `WalletScanModal.vue`, `ScreensaverRing.vue`) | — | Pure presentation; no backend involvement |
## Standard Stack
This phase does not introduce new external dependencies. It is a hardening + UI-surface pass over an existing Rust (Tokio/Hyper/reqwest/serde) backend and Vue 3 (Pinia, Vue Router, Teleport) frontend, plus a Node.js/Express demo backend (`neode-ui/mock-backend.js`). No new libraries are needed for any of FED-01 through FED-06 — `ScreensaverRing.vue` and `handle_lnd_openchannel` already exist and should be reused, not reimplemented.
### Core (existing, reused)
| Library | Version | Purpose | Why Standard |
|---------|---------|---------|--------------|
| tokio | (workspace pin) | Async runtime, `interval()`/`spawn()` for the periodic sync loops | Already the project's async foundation |
| reqwest | (workspace pin) | HTTP client for FIPS/Tor peer dial and LND REST calls | Already used throughout `fips/dial.rs` and `api/rpc/lnd/` |
| serde/serde_json | (workspace pin) | Wire format for `NodeStateSnapshot`, RPC params | Project-wide convention |
| Vue 3 + Pinia | (package.json pin) | Frontend reactivity/state | Existing frontend stack |
**Version verification:** No new packages are being added; skip registry verification per protocol (nothing to verify). If the planner introduces any new crate/npm package during execution, verify it then.
## Package Legitimacy Audit
No external packages are being introduced by this phase — this section is not applicable. If a later plan step decides to add a dependency (e.g., a curated public-LSP list requires a small crate), run the Package Legitimacy Gate at that time.

### Recommended Project Structure
No new directories needed. Touch points:
```
core/archipelago/src/federation/storage.rs # add locking around load/save
core/archipelago/src/server.rs # collapse or coordinate the two sync loops
core/archipelago/src/api/rpc/lnd/info.rs # extend handle_lnd_getinfo with identity_pubkey/uris
core/archipelago/src/federation/types.rs # (maybe) add lightning fields to NodeStateSnapshot
core/archipelago/src/api/rpc/federation/handlers.rs # (maybe) new RPC to fetch a peer's LN info
neode-ui/mock-backend.js # add mesh.contacts-list/save, stateful reaction/edit/delete
neode-ui/src/components/LightningChannelModal.vue # NEW — FED-05 (name TBD by planner)
neode-ui/src/components/SendBitcoinModal.vue # FED-06 swap
neode-ui/src/components/WalletScanModal.vue # FED-06 swap (secondary paid-tick site)
```
### Pattern 1: Federation removal is already "belt and suspenders" — reuse, don't rewrite
**What:** `handle_federation_remove_node` (handlers.rs:273) captures the peer's pubkey *before* calling `federation::remove_node`, then after removal calls `mesh::purge_federation_peer` to drop the synthetic mesh contact, its messages, presence, and persisted mesh-contacts entry. `federation::remove_node` (storage.rs:180) already tombstones the DID **before** saving the filtered node list and propagates a tombstone-write failure as an error (fixed in `01cbec27`).
**When to use:** This is the correct pattern for FED-01 already. Don't redesign it — the actual gap is the concurrency race in the storage layer underneath it (see Pitfall 1), not the removal logic itself.
**Example:**
```rust
// Source: core/archipelago/src/federation/storage.rs:180-198 (already fixed, 01cbec27)
pub async fn remove_node(data_dir: &Path, did: &str) -> Result<Vec<FederatedNode>> {
let mut nodes = load_nodes(data_dir).await?;
let before = nodes.len();
nodes.retain(|n| n.did != did);
if nodes.len() == before {
anyhow::bail!("No federated node with DID {}", did);
}
// Tombstone FIRST and propagate failure — a remove whose tombstone
// never landed isn't a remove.
tombstone_did(data_dir, did).await.context("persist removal tombstone")?;
save_nodes(data_dir, &nodes).await?;
Ok(nodes)
}
```
### Pattern 2: Transitive sync already respects tombstones — verify, don't re-add protection
**What:** `merge_transitive_peers` (sync.rs:120) loads `load_removed_dids()` and skips any hint whose DID is tombstoned, and `handle_federation_peer_joined` (handlers.rs:641) independently rejects a `peer-joined` callback for a tombstoned DID. Both paths that could resurrect a removed node already check the tombstone list.
**When to use:** The FED-03 review should write a test that concurrently exercises remove + an in-flight sync (see Pitfall 1) rather than re-deriving the (already-correct) tombstone-check logic.
### Pattern 3: Demo backend must be a byte-for-byte RPC mirror, not a "close enough" mock
**What:** `mock-backend.js`'s `mesh.transport-advice` case (line 4318) explicitly duplicates the daemon's size thresholds (`MESH_AUTO_MAX = 1024`, `MESH_HARD_MAX = 2300`) with a comment pointing at `typed_messages.rs handle_mesh_transport_advice` as the source of truth.
**When to use:** Apply the same pattern to `mesh.contacts-list`/`mesh.contacts-save` and to the reaction/edit/delete stubs — read the real handler in `core/archipelago/src/api/rpc/mesh/typed_messages.rs` (lines 1180-1371 for contacts/presence, 637-976 for reply/reaction/receipt/forward, 1065-1180 for edit/delete) and mirror its actual state transitions in `meshStore.dynamic`, not just an `{ok:true}` ack.
### Anti-Patterns to Avoid
- **Unlocked read-modify-write on shared JSON files:** `federation/storage.rs` has none of `load_nodes()`/`save_nodes()` behind a mutex, and writes are a direct `fs::write()` (not atomic temp+rename). Any new federation code must NOT add a third code path that does its own read-modify-write without going through a shared lock — that widens the race window instead of closing it.
- **Silent `debug!()` on periodic-loop errors:** Both sync loops in `server.rs` log sync failures at `debug!` level only (not surfaced to the state broadcast, not visible in the UI). FED-02 explicitly requires operator-visible sync errors — don't add a third silent loop; extend the existing ones to persist a `last_sync_error` alongside `last_seen`.
- **Reinventing `handle_lnd_openchannel`'s connect-then-open sequence:** It already does `perm=false` synchronous peer connect before opening (with a documented reason: `perm=true` races and fails with "peer is not online"). Reuse it; do not write a second Lightning-channel RPC.
- **Assuming `ScreensaverRing` is pre-sized for a 112px success badge:** its `compact` class is 240px (mobile) / 320px (≥768px) — 2-3x the current `.send-success-burst`. Naive drop-in will overflow the modal card; must be explicitly scaled or the surrounding layout redesigned.
## Don't Hand-Roll
| Problem | Don't Build | Use Instead | Why |
|---------|-------------|-------------|-----|
| Connecting to + opening a channel with an LN peer | A new RPC | `lnd.openchannel` (`api/rpc/lnd/channels.rs:238`) | Already validates pubkey format, amount bounds, fee params, and does the connect-before-open sequence correctly with the documented `perm=false` fix |
| Paid/success radial visual | A new ring/particle component | `ScreensaverRing.vue` (`compact` size) | Explicitly required by FED-06; also already ships a reduced-motion-friendly animation pattern to copy for consistency |
| Peer transport badge (FIPS/Tor) | New transport-tracking logic | `FederatedNode.last_transport`/`last_transport_at` (already written by `record_peer_transport`) | Already ground-truth (records what was actually used, not predicted) — FED-05's peer picker can reuse this field to show reachability |
| Federated-peer list for the "trusted nodes" picker | A new RPC | `federation.list-nodes` (already returns `did`, `name`, `onion`, `trust_level`, `last_seen`) | FED-05 only needs to ADD Lightning fields to this payload/peer lookup, not build a parallel peer list |
**Key insight:** Almost every piece of infrastructure FED-01/02/04/05 need already exists in some form — the gaps are narrow (a missing lock, a missing mock method, a missing struct field) rather than missing subsystems. Resist the urge to redesign the federation sync architecture; patch the specific race and the specific parity/field gaps identified here.
## Common Pitfalls
### Pitfall 1: Unlocked concurrent read-modify-write on `federation/nodes.json` (PRIMARY SUSPECT for FED-01/FED-02)
**What goes wrong:** A federated node the operator removes reappears after "some sync cycles," with no error anywhere — exactly the symptom reported. `federation::remove_node()` and `federation::sync::update_node_state()` (called from `sync_with_peer()`) both do `load_nodes()` → mutate in memory → `save_nodes()` with zero mutex and a non-atomic `fs::write()`. Two async tasks (e.g., the 90s auto-sync loop mid-flight for peer X, and a `federation.remove-node` RPC for the same peer X arriving concurrently) can interleave: the sync task's `load_nodes()` snapshot (taken before the removal) still contains X; the removal completes and saves a list without X; the sync task then finishes and calls `save_nodes()` with its stale in-memory list, silently restoring X.
**Why it happens:** No `Mutex`/`RwLock` guards the federation JSON files, and there are TWO independent periodic sync loops (`server.rs` ~line 497, every 90s; ~line 840, every 1800s — the second loop's comment even says "every 30 min" while the interval literal is `Duration::from_secs(1800)`, i.e. that arithmetic is correct but the redundancy with the 90s loop is not otherwise explained or justified anywhere in the code) plus manual "Sync All" and remove/join/set-trust RPCs, all writing the same file.
**How to avoid:** Add a per-data-dir `tokio::sync::Mutex<()>` (or an `Arc<Mutex<Vec<FederatedNode>>>` cache) that every `federation::storage` read-modify-write function acquires for the duration of its load+mutate+save; consider switching `save_nodes` to atomic temp-file+rename to avoid partial-write corruption on crash. Separately, evaluate collapsing the two periodic sync loops into one (the 90s loop already does everything the 1800s loop does, plus asymmetry self-heal) — the 1800s loop appears vestigial/redundant and doubles the race exposure for no described benefit.
**Warning signs:** `tests/multinode/smoke.sh`'s "removed-node tombstone" section (already covers the transitive-reappear case) intermittently fails only under load/timing variance, or a removed node's `last_seen` timestamp updates *after* a `federation.remove-node` call succeeded — that's the race manifesting as reappearance without any logged error.
### Pitfall 2: Trusting `CONCERNS.md` as current state for this phase
**What goes wrong:** Re-fixing an already-fixed bug (tombstone-write-swallowed was fixed in `01cbec27`, 2026-07-02) wastes the FED-03 review's time and risks reintroducing a regression if the "fix" reverts working code.
**Why it happens:** `CONCERNS.md` was generated 2026-07-29 from a static codebase snapshot/analysis pass that in at least two documented cases (tombstone swallow, DID-join-without-verification) predates fixes already on `main`.
**How to avoid:** For every `CONCERNS.md` federation/mesh item, `git log -p` the referenced file/line range before deciding it's still open. Two items already verified fixed in this research: "Federation node removal tombstone gap" (fixed `01cbec27`) and part of "Federation DID validation incomplete" (the `peer-joined` RPC does require and verify an ed25519 signature — `handlers.rs:588-607`). The remaining un-verified part of that concern — no proof-of-ownership check on the *original* DID mint, i.e. can anyone claim any DID string on first contact — may still be valid; verify it during the review rather than assuming either way.
**Warning signs:** A "finding" in the FED-03 review that exactly matches a `CONCERNS.md` bullet without a fresh code read is a signal to re-verify before filing it.
### Pitfall 3: Demo mock silently no-ops instead of erroring on unmirrored RPCs
**What goes wrong:** `mesh.contacts-list`/`mesh.contacts-save` are called live from `Mesh.vue` (lines 113, 896) but have no case in `mock-backend.js`'s switch — they fall through to the `default` case which returns a proper JSON-RPC error (`Method not found`), but the frontend call sites wrap them in `try {} catch { /* non-fatal */ }`, so the failure is invisible during manual demo testing unless you watch the browser console or server log (`console.log('[RPC] Unknown method: ...')`).
**Why it happens:** New frontend RPC call sites get added over time; `mock-backend.js` parity is manual and easy to miss for methods that aren't on the "main" flow (aliasing a peer is a secondary action, not part of onboarding/attach-file).
**How to avoid:** Grep `neode-ui/src/api/rpc-client.ts` for every `mesh.*`/`federation.*` method string and cross-reference against `mock-backend.js`'s switch cases as an explicit FED-03/FED-04 checklist item, not just the attachment-send path already fixed.
**Warning signs:** Browser console shows `[RPC] Unknown method: mesh.contacts-list` while testing the demo at `:8100`.
### Pitfall 4: `ScreensaverRing`'s size classes don't have a "success-badge" variant
**What goes wrong:** Dropping `<ScreensaverRing size="compact" />` directly into `.send-success-burst` (currently 112px) either overflows the card or looks disproportionate at 240-320px without adjusting the surrounding layout.
**Why it happens:** `ScreensaverRing.vue`'s two size classes (`viz-ring-default`, `viz-ring-compact`) were designed for full-screen screensaver and settings-panel contexts (`SystemDangerZone.vue`), not for an inline modal success pane.
**How to avoid:** Either (a) wrap the component in a container with `transform: scale(0.5)` (112/240 ≈ 0.47) and compensate for the transform not affecting layout box size (use negative margins or a fixed wrapping box), or (b) add a third `compact-sm`/`badge` size variant to `ScreensaverRing.vue` sized for this use case (cleaner, and reusable for `WalletScanModal.vue`'s `.success-ring` too). Confirm the choice with a UI-spec/sketch before implementation given this affects two components.
**Warning signs:** Visual QA on `:8100` shows the ring clipped by the modal's `max-h-[90vh] overflow-y-auto` container or the checkmark badge floating disconnected from the ring's visual center.
### Pitfall 5: FED-05 has no backend field for a peer's Lightning identity
**What goes wrong:** Building the "trusted nodes by hostname, one-click channel open" UI before the backend can supply a federated peer's LN `pubkey`/`host:port` results in a UI that can list *names* but has nothing to pass to `lnd.openchannel`.
**Why it happens:** `NodeStateSnapshot` (the payload `federation.get-state`/sync exchanges) has no Lightning fields at all — it was designed for app/CPU/mem/tor status, not payment-channel metadata.
**How to avoid:** Plan FED-05 backend-first: (1) extend `handle_lnd_getinfo` to parse and return `identity_pubkey` + `uris` from LND's real `/v1/getinfo` response (both fields already exist in LND's REST API — the daemon's `LndGetInfoResponse` struct just doesn't deserialize them yet), (2) add optional `lightning_pubkey`/`lightning_uri` fields to `NodeStateSnapshot` so a synced peer's info includes it (defaulted via `#[serde(default)]` for backward compat, matching every other optional field in that struct), (3) decide and scope the "public nodes" browse/request feature — no existing data source; recommend a small curated static list (documented, versioned) rather than a live LN graph query (`DescribeGraph` is heavy and not currently proxied anywhere in this codebase) unless the user specifically wants live graph browsing.
**Warning signs:** A plan step that starts building `LightningChannelModal.vue` before a corresponding backend RPC/field change is scoped — check the plan's task ordering.
## Code Examples
### Reuse: opening a channel (backend already correct)
```rust
// Source: core/archipelago/src/api/rpc/lnd/channels.rs:238-336 (excerpted)
// Params: { pubkey: <66-hex>, amount: <sats>, address?: <host:port>, private?, target_conf?, sat_per_vbyte? }
// Validates pubkey format + amount bounds (20,000..=16,777,215 sats) before touching LND.
// Connects to the peer synchronously (perm=false) before opening so "peer not online" is
// surfaced deterministically instead of racing the open.
```
### Reuse: transport badge already ground-truth per peer
```rust
// Source: core/archipelago/src/federation/storage.rs:120-147
// record_peer_transport() writes last_transport/last_transport_at after every
// successful PeerRequest — the FED-05 peer picker can show "reachable via FIPS"
// / "reachable via Tor" per trusted node without any new plumbing.
```
### Gap: demo mesh chat action stubs don't mutate state
```javascript
// Source: neode-ui/mock-backend.js:4479-4490 (current — needs to become stateful)
case 'mesh.send-reaction':
case 'mesh.send-reply':
case 'mesh.send-read-receipt':
case 'mesh.edit-message':
case 'mesh.delete-message':
case 'mesh.forward-message':
case 'mesh.send-channel':
case 'mesh.refresh':
case 'mesh.reboot-radio': {
return res.json({ result: { ok: true, sent: true } }) // no meshStore.dynamic mutation
}
```
## State of the Art
| Old Approach | Current Approach | When Changed | Impact |
|--------------|------------------|---------------|--------|
| Tombstone write silently dropped (`let _ = tombstone_did(...)`) | Tombstone write propagated as a hard error, written before the node-list save | 2026-07-02, `01cbec27` | A failed tombstone write now fails the whole remove — matches FED-01's "a failed removal surfaces an error" requirement already, at the single-call level (the remaining gap is the cross-call race in Pitfall 1) |
| Mesh attachment send: demo threw "Method not found" and force-opened a demo-only chooser modal | `mock-backend.js` implements the same RPC surface + mirrors the real size-tier logic | 2026-07-29, `c2ce71c6` | FED-04's core attachment-parity requirement is met; remaining gaps are contacts and reaction/edit/delete (see Pitfall 3) |
**Deprecated/outdated:** None specific to this phase's tech; no framework/library version churn involved.
## Assumptions Log
| # | Claim | Section | Risk if Wrong |
|---|-------|---------|---------------|
| A1 | The unlocked read-modify-write race on `federation/nodes.json` (Pitfall 1) is the primary cause of the user-reported "nodes reappear / sync issues" — this is a code-derived hypothesis, not confirmed via a reproduced failure in this research session | Summary, Pitfall 1 | If wrong, the planner should still fix the race (it's a real bug regardless) but should budget review time for other causes too — start FED-03 with a broader look, not a narrow patch-and-close on this one hypothesis |
| A2 | The 1800s periodic federation sync loop (`server.rs` ~line 840) is redundant given the 90s loop and safe to remove/collapse | Pitfall 1, Anti-Patterns | If a maintainer added it for a specific reason not documented in the surrounding comments (e.g. covering a case the 90s loop misses), removing it could regress that unstated behavior — confirm via `git log -p` / git blame on that block before deleting |
| A3 | "Public nodes" for channel-open browse/request (FED-05) should be a small curated static list rather than a live LN network graph query | Pitfall 5 | If the user actually wants live graph discovery, the curated-list approach under-delivers; this needs explicit user confirmation before FED-05 backend work starts |
| A4 | `ScreensaverRing`'s size mismatch with `.send-success-burst` should be solved with a CSS scale-down rather than a new component size variant | Pitfall 4 | Either approach works technically; scale-down is faster but may look slightly different under `prefers-reduced-motion`; a new size variant is cleaner but touches the shared component. Low risk either way — a UI sketch/spec pass can decide before implementation |
| A5 | The remaining "Federation DID validation incomplete" concern (no proof-of-ownership check on first DID mint) is still an open gap, not yet fixed like its sibling claims | Pitfall 2 | Not independently re-verified in this session (only the peer-joined signature check was confirmed); FED-03 should explicitly re-check this specific sub-claim before filing or dismissing it |
**If this table is empty:** N/A — see rows above.
## Open Questions
1. **Is the two-loop federation sync redundancy intentional?**
- What we know: Both loops call `sync_with_peer` over all `Trusted`/`Observer` nodes; only the 90s loop does the "asymmetry self-heal" `notify_join` re-assertion; the 1800s loop additionally calls `refresh_federation_mesh_peers()` after its full pass (the 90s loop does not).
- What's unclear: Whether the 1800s loop's `refresh_federation_mesh_peers()` call covers a gap the 90s loop leaves (e.g. name/roster propagation to mesh chat), which would mean simply deleting it regresses something.
- Recommendation: `git log -p` / blame both loop-insertion commits during FED-03; if the mesh-peer-refresh behavior is the only unique value of the 1800s loop, move that single call into the 90s loop's completion and delete the 1800s loop entirely, closing half the race window.
2. **What UI/UX should "browse/request channels with public nodes" (FED-05) actually look like?**
- What we know: No existing data source; `lnd.openchannel` supports a manual pubkey+address entry today (a user could theoretically paste a public node's URI already, just with no picker/browse UI).
- What's unclear: Whether "public nodes" means (a) a curated list Archipelago ships/updates, (b) a live query against some LSP directory API, or (c) simply a well-labeled manual-paste field with format help (lowest-effort, matches what the backend already supports).
- Recommendation: Flag for `/gsd-discuss-phase` or a direct user check-in before FED-05 planning — this is a scope decision, not a technical one.
3. **Does `federation.get-state`'s `federated_peers` hint list need a Lightning field, or should peer LN info be a separate on-demand RPC?**
- What we know: `NodeStateSnapshot.federated_peers` already carries a lightweight `FederationPeerHint` (did/pubkey/onion/name/fips_npub) shared during sync; adding `lightning_uri` there means every synced peer's LN info is cached locally without an extra round-trip.
- What's unclear: Whether peers want to opt out of advertising their LN URI transitively (privacy consideration, similar to the existing `shared_location` opt-in pattern for lat/lon).
- Recommendation: Follow the `shared_location` precedent (`Option<(f64,f64)>` only sent when the node opts in via `server.set-location`) — add an explicit opt-in setting for Lightning URI sharing rather than defaulting it on, since exposing a payment channel target more broadly than intended has real-money implications.
## Environment Availability
| Dependency | Required By | Available | Version | Fallback |
|------------|------------|-----------|---------|----------|
| Rust toolchain / cargo (from `core/`) | FED-01/02/03/04 backend work | Not probed this session (assume present per CLAUDE.md build instructions) | — | — |
| Node.js / npm (`neode-ui/`) | FED-04/05/06 frontend + mock-backend.js work | Not probed this session (assume present per CLAUDE.md build instructions) | — | — |
| `:8100` dev preview proxying to archi-dev | FED-05/06 required verification step per phase description | Not probed this session — verify at execution time per `docs/../reference_neode_ui_dev_testing.md` (mock=5959, pw password123) | — | — |
| LND REST API (`LND_REST_BASE_URL`, local macaroon) | FED-05 `lnd.getinfo` extension + `lnd.openchannel` reuse | Assumed present on real nodes per existing `channels.rs`/`info.rs` code; demo backend has no real LND — FED-05 UI must be exercised against archi-dev (real LND) per phase description, not the pure-mock demo | — | Demo-only mock stub for `lnd.getinfo` identity fields if archi-dev is unavailable during a work session |
| `tests/multinode/smoke.sh` | Regression coverage for FED-01/02 fix | Present, already covers removed-node tombstone + transitive-reappear scenarios; does NOT currently exercise the concurrent-race scenario (Pitfall 1) | — | Extend smoke.sh with a concurrent remove+sync test, or add a Rust-level `#[tokio::test]` in `federation/storage.rs` that spawns concurrent remove/save calls |
**Missing dependencies with no fallback:** None identified — this phase is code-only, no new external services.
**Missing dependencies with fallback:** LND-backed FED-05 verification (see row above) — use archi-dev per phase instructions; demo-only stubbing is a fallback if archi-dev is temporarily unavailable, but the phase's own success criteria require verification against archi-dev before deploy, so this fallback should not be treated as sufficient sign-off.
## Validation Architecture
### Test Framework
| Property | Value |
|----------|-------|
| Framework (backend) | `cargo test` (Rust, workspace root `core/`) — federation/storage.rs and federation/sync.rs already have `#[tokio::test]` unit coverage |
| Framework (frontend) | Vitest (`neode-ui/vitest.config.ts`, `vitest run`) |
| Config file | `core/Cargo.toml` (workspace); `neode-ui/vitest.config.ts` |
| Quick run command | `cd core && cargo test -p archipelago federation:: --lib` (backend); `cd neode-ui && npx vitest run src/components/__tests__/` (frontend, scope to touched files) |
| Full suite command | `cd core && CARGO_INCREMENTAL=0 cargo test` (backend, full); `cd neode-ui && npm run test` (frontend, full); `tests/multinode/smoke.sh` (cross-node, requires 2+ live nodes, run on-node per CLAUDE.md gate policy) |
### Phase Requirements → Test Map
| Req ID | Behavior | Test Type | Automated Command | File Exists? |
|--------|----------|-----------|-------------------|-------------|
| FED-01 | Removed node never reappears, incl. under concurrent sync | unit + integration | `cargo test -p archipelago federation::storage::tests` (existing) + NEW concurrent-race test | ✅ existing tests / ❌ Wave 0 for the new race test |
| FED-01 | Failed removal surfaces an error, not a silent no-op | unit | `cargo test -p archipelago federation::storage::tests::test_remove_nonexistent_node_errors` (existing, covers the "not found" case; add one for a simulated tombstone-write I/O failure) | ✅ existing / ❌ Wave 0 for I/O-failure case |
| FED-02 | Sync converges; fleet nodes agree on node list | integration (multinode) | `tests/multinode/smoke.sh` section "federation pairing" + "removed-node tombstone" (existing) | ✅ |
| FED-02 | Sync errors are operator-visible | manual / UI | No automated test yet — requires a UI element (e.g. per-node "last sync error" badge) that doesn't exist yet | ❌ Wave 0 (needs the field to exist first) |
| FED-03 | Structured review findings fixed or deferred with reason | N/A (process requirement) | N/A — tracked via the plan's findings list, not a single automated test | — |
| FED-04 | Attachment send parity demo vs real | manual (visual) + existing `mock-backend.js` logic mirrors daemon tier thresholds | Manual walk-through on `:8100` per phase description; consider a Vitest test asserting `mesh.transport-advice` tier boundaries match `MESH_AUTO_MAX`/`MESH_HARD_MAX` constants | ❌ Wave 0 (no existing frontend test pins these thresholds) |
| FED-04 | Contacts list/save + reaction/edit/delete parity | manual + NEW mock-backend.js stateful behavior | Manual on `:8100`; no existing automated coverage of `mock-backend.js` behavior (it's a dev tool, not covered by `npm run test`) | ❌ Wave 0 if automated coverage is wanted; otherwise manual-only is acceptable for a demo shim |
| FED-05 | Own node Lightning URI is shareable | unit (backend) + manual (UI) | NEW `cargo test` for `handle_lnd_getinfo`'s identity_pubkey/uris parsing (mock LND response fixture); manual UI check on archi-dev | ❌ Wave 0 |
| FED-05 | Trusted-node picker + channel open flow | manual (UI, requires archi-dev + a live peer) | Manual per phase description ("tested live on the :8100 dev preview against archi-dev") | ❌ Wave 0 — inherently a live/manual check per the phase's own success criteria |
| FED-06 | Paid-tick animation matches screensaver ring everywhere it appears | manual (visual) | Manual visual check of `SendBitcoinModal.vue` + `WalletScanModal.vue` on `:8100` | ❌ Wave 0 — visual-only requirement, no meaningful automated assertion beyond "component renders" |
### Sampling Rate
- **Per task commit:** Backend: `cargo test -p archipelago federation:: mesh::` (scoped). Frontend: `npx vitest run` scoped to touched component test files, or a full quick run if none exist yet for touched files.
- **Per wave merge:** Full `cargo test` (backend) + `npm run test` (frontend).
- **Phase gate:** Full backend + frontend suites green, plus `tests/multinode/smoke.sh` federation sections green on a real 2-node pair, plus a manual FED-05/FED-06 walkthrough on `:8100` against archi-dev before any deploy (per phase description, "fixed there before any deploy").
### Wave 0 Gaps
- [ ] New `#[tokio::test]` in `core/archipelago/src/federation/storage.rs` (or a new integration test) that spawns concurrent `remove_node()` + `update_node_state()`/`sync_with_peer`-equivalent calls against the same `data_dir` and asserts the removed node stays removed — this is the regression test for Pitfall 1 and does not exist today.
- [ ] Test/fixture for `handle_lnd_getinfo` parsing `identity_pubkey`/`uris` from a mocked LND `/v1/getinfo` JSON response (FED-05) — no existing test touches this handler's response shape.
- [ ] Decide whether `mock-backend.js` behavior warrants automated (Vitest/Playwright-against-mock) coverage, or manual-only is acceptable given it's a dev-preview tool, not shipped code — recommend manual-only unless the team already has a pattern for testing the mock backend elsewhere (none found in this research).
- [ ] Framework install: none — all frameworks (`cargo test`, Vitest) are already configured and running.
## Security Domain
### Applicable ASVS Categories
| ASVS Category | Applies | Standard Control |
|---------------|---------|-----------------|
| V2 Authentication | Partial | Federation peer identity is DID/ed25519-key-based, not password auth; `peer-joined`/`peer-did-changed`/`peer-address-changed` all require and verify an ed25519 signature over a canonical message before mutating state — already correct, verify no new RPC bypasses this |
| V3 Session Management | No | Not applicable — federation/mesh RPCs are peer-signed, not session-cookie based |
| V4 Access Control | Yes | `is_peer_allowed_path()` (`server.rs:1270`, tested at `server.rs:2075+`) restricts which HTTP paths a peer-only listener will serve — any new FED-05 RPC (e.g. "fetch peer's Lightning URI") that's meant to be peer-reachable must be added to this allow-list explicitly, not left to fall through |
| V5 Input Validation | Yes | `lnd.openchannel` already validates pubkey format (66-hex) and amount bounds server-side (`channels.rs:252-268`) — reuse, and apply the same rigor to any new Lightning-URI-sharing field (validate the URI format before persisting/displaying it) |
| V6 Cryptography | Yes | ed25519 signature verification via `identity::NodeIdentity::verify` — never hand-roll signature checks; reuse this existing verification path if FED-05 needs to authenticate a peer's advertised Lightning info |
### Known Threat Patterns for this stack
| Pattern | STRIDE | Standard Mitigation |
|---------|--------|---------------------|
| Federation peer spoofing a DID they don't control | Spoofing | ed25519 signature verification (already implemented for join/address-change/did-rotation — confirm any new FED-05 peer-info exchange follows the same pattern) |
| Concurrent-write race corrupting/reverting federation state (Pitfall 1) | Tampering (unintentional, but security-relevant since it undermines the "removal sticks" guarantee — a removed/untrusted peer regaining federation membership is a real access-control regression) | Add locking around the storage layer (see Pitfall 1's fix) |
| Unbounded transitive federation exposure (a Trusted peer's peer list auto-added as Observer) | Elevation of Privilege (bounded) | Already mitigated — `merge_transitive_peers` only runs for `Trusted`-level sources and only adds new peers as `Observer` (never auto-escalates to `Trusted`); this is intentional and correct, don't loosen it |
| Advertising this node's Lightning payment-channel target more broadly than intended (FED-05 new surface) | Information Disclosure | Follow the existing `shared_location` opt-in pattern — do not default Lightning URI sharing to "on" for all federated peers (see Open Question 3) |

## Metadata
**Confidence breakdown:**
- Standard stack: HIGH — no new dependencies; existing stack confirmed by direct file reads
- Architecture (FED-01/02/03/04): HIGH — read the actual implementation, confirmed fix history via git log, identified a concrete unverified race condition with file:line citations
- Architecture (FED-05): MEDIUM — greenfield UI/RPC surface; confirmed what's missing (no existing Lightning-URI field/RPC) but the design (opt-in sharing, public-nodes scope) needs a user decision, not just engineering judgment
- Pitfalls: HIGH for Pitfalls 1-3 (backend/demo, code-verified); MEDIUM for Pitfalls 4-5 (frontend sizing and FED-05 scope, judgment calls flagged in Assumptions Log)

| Component library | none — hand-authored Tailwind utilities + a custom "glass" CSS system (`glass-card`, `glass-button`, `glass-button-warning/danger/success`, `input-glass`, `alert-error/warning/info`, `BaseModal.vue`) defined in `neode-ui/src/style.css` and reused project-wide |
| Icon library | none — inline hand-authored SVG, 24×24 viewBox, `stroke-width="2"` outline style (heroicons-esque but not the package). The bolt path `M13 10V3L4 14h7v7l9-11h-7z` is already the house Lightning icon (used in `Server.vue`, `HomeWalletCard.vue`, `Web5Wallet.vue`) — reuse it verbatim for any new Lightning iconography in FED-05, do not source a new icon. |
| Font | Avenir Next (`font-sans`, body/UI text), Montserrat 700/800 (`font-archipelago`, headers only — not used in modals) |
**Modal contract (hard rule, repeated user complaint):** Every new modal in this phase MUST use `BaseModal.vue` (already wraps `Teleport to="body"` + full-screen `bg-black/60 backdrop-blur-md` backdrop + column layout with pinned header/footer and scrolling body) or, if a bespoke modal is unavoidable, MUST replicate that exact `<Teleport to="body">` + `fixed inset-0` + `@click.self="close"` pattern. Never nest a modal inside a `transform`-affected ancestor (glass-panel `translateZ` layers trap `position:fixed`).
---
## Spacing Scale
Declared values (must be multiples of 4) — matches `tailwind.config.js`'s existing 4px-grid `spacing` tokens (`1`=4px … `8`=32px) plus standard Tailwind rem multiples used throughout the codebase for larger gaps:
| Token | Value | Usage |
|-------|-------|-------|
| xs | 4px | Icon-to-label gaps, badge padding |
| sm | 8px | Compact row spacing, `gap-2` |
| md | 16px | Default element spacing, `p-4` card padding |
| lg | 24px | Section padding, `mb-6` between panel sections |
| xl | 32px | Layout gaps between major picker columns |
| 2xl | 48px | `py-12` empty-state vertical padding |
| 3xl | 64px | Not used by this phase's new elements |
Exceptions: 44px minimum touch target on all new interactive buttons (global rule already enforced in `style.css` for mobile — the "Copy URI" / "Open Channel" / "Request Channel" buttons inherit `min-height: 44px` from `.glass-button` automatically, no override needed).
---
## Typography
Scoped to this phase's new elements only (existing typography elsewhere is unchanged). Exactly two weights govern this phase's new elements — 400 and 600; Label and Body are differentiated from each other by size and color (not weight), matching how `NodeList.vue` already distinguishes node-name text from badge/hint text:
| Role | Size | Weight | Line Height |
|------|------|--------|-------------|
| Label | 12px (`text-xs`) | 400 (regular), `text-white/60` | 1.4 |
| Body | 14px (`text-sm`) | 400 (regular), `text-white` | 1.5 |
| Heading | 20px (`text-xl`) | 600 (semibold) | 1.3 |
Heading is pinned to `text-xl` (20px), not a range — this matches `BaseModal.vue`'s own `<h3 class="text-xl font-semibold">` title (the component every new modal in this phase must use per the Modal contract above) and `WalletScanModal.vue`'s pane title, i.e. the size the existing house modals actually use most for their titles. Modal titles ("Open Lightning Channel", "Request Channel") use Heading; node names use Body (`text-white`); URI strings, badges, and helper/meta text use Label (`text-white/60`) per the existing `LightningChannelsPanel.vue`/`NodeList.vue` convention.
**Inherited — not governed by this contract:** The `SendBitcoinModal.vue`/`WalletScanModal.vue` success-amount numerals (e.g. `12,345 sats`, `text-5xl font-black` — 48px / weight 800) are pre-existing, unchanged display text. FED-06 only replaces the ring graphic behind/around that text, never the text itself, so this weight/size falls outside the phase's new-elements typography contract above and is not counted toward its weight budget.
---
## Color
| Role | Value | Usage |
|------|-------|-------|
| Dominant (60%) | `#000000` + `rgba(0,0,0,.35–.65)` | Page background, `.glass`/`.glass-card` surfaces |
| Secondary (30%) | `rgba(0,0,0,.65)` blur(18px) card, `rgba(255,255,255,.05–.08)` nested rows | Modal cards, picker list rows (`bg-black/20` per-node rows, `bg-white/5` nested detail blocks) |
| Accent (10%) | Archipelago orange `#fb923c` / `rgba(251,146,60,*)` | **Reserved for:** the "Open Channel" / "Request Channel" / "Copy Lightning URI" primary CTA buttons (`.glass-button-warning`), the Lightning bolt icon fill, focus-visible glow rings, the active picker-tab underline (mirrors existing `.mode-switcher-btn-active` treatment) |
| Destructive | `#ef4444` family (`.glass-button-danger`) | Not used by FED-05 v1 (no destructive action ships this phase — channel *close* is existing, out-of-scope UI in `LightningChannelsPanel.vue`); declared for consistency if a future "revoke URI sharing" action is added |
**Inherited semantic colors (pre-existing house convention, unchanged by this phase, NOT part of the 10% accent budget):**
- Success/paid emerald `#4ade80` text / `rgba(16,185,129,*)` fills — the paid-tick's center badge and "SENT"/amount numerals (FED-06 keeps this palette; only the surrounding ring geometry changes).
- Info blue `#60a5fa` — FIPS/Tor transport badges already shown next to trusted-node rows (`NodeList.vue`'s `transportBadge`); reused as-is in the FED-05 trusted-node picker rows, not introduced by this phase.
Accent reserved for: **primary Lightning-channel action buttons, the Lightning bolt icon, focus rings, and the active picker-tab indicator only** — never for body text, card backgrounds, or informational badges.
---
## Copywriting Contract
| Element | Copy |
|---------|------|
| Primary CTA — own URI | **"Copy Lightning URI"** (copy-to-clipboard button; on success the label flips to **"Copied!"** for ~2s, mirroring `SendBitcoinModal.vue`'s existing `copyDetail`/`Copied!` pattern — do not invent a new copy-feedback idiom) |
| Primary CTA — trusted federated node | **"Open Channel"** (one-click; matches the verb already used in `LightningChannelsPanel.vue`'s existing Open Channel button/modal) |
| Primary CTA — meshed Lightning peer | **"Request Channel"** (opens the request flow reusing `PeerRequestModal.vue`'s pattern — optional message field, "Send Request" submit button, `sending` → **"Sending…"** busy label — do not build a new request-modal component from scratch) |
| Manual fallback entry point | **"Paste URI Manually"** (reveals a `Peer URI` input, placeholder `pubkey@host:port`, helper text `Format: pubkey@host:port` — verbatim reuse of `LightningChannelsPanel.vue`'s existing field copy) |
| Empty state heading | **"No Lightning peers yet"** |
| Empty state body | **"Add a federated node or connect with a meshed peer running Lightning to open a channel directly — or paste a peer's URI manually below."** |
| Error state | **"Couldn't reach that peer — check they're online and try again."** (tone/placement mirrors the existing `openError`/`alert-error` treatment in `LightningChannelsPanel.vue`; LND "still starting up" transient errors reuse that same component's amber `isStartupNotice` treatment rather than the red error style) |
| Destructive confirmation | Not applicable — FED-05 v1 ships open/request flows only, no destructive action |
| FED-06 copy | Not applicable — pure visual swap. Existing "SENT" / success-amount / "Done" button copy in `SendBitcoinModal.vue` and `WalletScanModal.vue` is unchanged; only the ring graphic behind the checkmark changes. |

## UI Considerations
Applicable state considerations resolved: 13 covered, 3 backstop, 0 unresolved.
| Category | Element(s) | Status | Resolution / Reason |
|----------|------------|--------|---------------------|
| long-text | own-node URI display | ✅ covered | The displayed `pubkey@host:port` string truncates (CSS `truncate` + `title` tooltip, the existing house pattern) to fit its container; the full untruncated value is what gets copied to clipboard regardless of visual truncation |
| empty | trusted-nodes picker list | ✅ covered | Empty state copy row above renders once when both the trusted and meshed-peer lists are empty (shared empty state, not duplicated per column) |
| empty | meshed-LN-peers picker list | 🧪 backstop | Same shared empty-state copy as above; no wired test yet asserting the "shared, not duplicated" rendering rule — flag for planner/executor to add a component test |
| loading | trusted-nodes picker list | ✅ covered | Mirrors `NodeList.vue`'s existing "Loading nodes..." spinner row treatment |
| loading | meshed-LN-peers picker list | ✅ covered | Same spinner treatment as trusted-nodes list |
| error | trusted-nodes / meshed-peer picker lists | ✅ covered | Ties to the Copywriting Contract error row; styled with `.alert-error`/`openError` convention already in `LightningChannelsPanel.vue` |
| populated | trusted-nodes picker list | ✅ covered | Row layout mirrors `NodeList.vue`'s trusted-node row: name, trust badge, transport badge (FIPS/Tor), one-click "Open Channel" button |
| populated | meshed-LN-peers picker list | ✅ covered | Same row layout, "Request Channel" button in place of "Open Channel" (peers are not bilaterally trusted, so the action is a request, never a direct open) |
| zero-one-many | trusted-nodes / meshed-peer lists | ✅ covered (dismissed) | No item-count copy is planned for either list (unlike e.g. the channel-status tabs' count badges) — singular/plural phrasing is not applicable |
| overflow | picker list rows (long node names) | ✅ covered | `truncate` class + `:title` tooltip on the node-name span, identical to the existing `NodeList.vue` convention |
| partial | manual-URI-paste form | ✅ covered | A pasted pubkey without a host falls back to `lnd.openchannel`'s existing address-less-pubkey handling (`address = parts[1] \|\| undefined`), already proven in `LightningChannelsPanel.vue` |
| error | manual-URI-paste form | 🧪 backstop | Invalid-format message ("Peer URI must be `pubkey@host:port`") is specified but no explicit format-validation test is scoped yet — planner should add one, do not silently skip client-side validation before calling `lnd.openchannel` |
| long-text | manual-URI-paste form | ✅ covered | Same truncation/tooltip treatment as the own-node URI display |
| unclassified | request-to-open-channel flow | ✅ covered (dismissed) | Reuses `PeerRequestModal.vue` verbatim (message field, Send Request/Sending states) — its own state coverage predates this phase and is not re-specified here |
| long-text | paid-tick ring (`SendBitcoinModal.vue` + `WalletScanModal.vue`) | ✅ covered (dismissed) | The ring itself renders no text content (pure SVG/CSS segments); the 48px sats amount inside it is inherited text explicitly out of this contract (see Typography inherited note) |
| overflow | paid-tick ring (`SendBitcoinModal.vue` + `WalletScanModal.vue`) | ✅ covered | New `badge` `ScreensaverRing` size variant (see below) is explicitly sized to fit inside the modal's `max-h-[90vh] overflow-y-auto` card without clipping — do not drop in the existing `compact` (240–320px) variant unscaled |
| static-content (motion) | paid-tick ring, all `ScreensaverRing` size variants | 🧪 backstop | `ScreensaverRing.vue`'s `segment-pulse` animation currently has **no** `prefers-reduced-motion` guard anywhere (a real gap — confirmed by reading the component; contrast with `SendBitcoinModal.vue`'s existing `.burst-ring`, which already has one). This phase must add `@media (prefers-reduced-motion: reduce) { .viz-segment { animation: none; opacity: 0.6; } }` inside `ScreensaverRing.vue` itself so the guard applies to every size variant (including the new `badge` one), matching the site-wide reduced-motion convention. No existing automated test covers this — flag for planner as a Wave 0 test gap. |
<!-- Status vocabulary (locked by probe-core projectTruths):
✅ covered → a plain truth string lifted into must_haves.truths
🧪 backstop → a flat scalar { statement, verification: backstop }; at verify time, no explicit
evidence → insufficient_spec → human_needed (never a silent pass, #1154)
⚠ unresolved → an explicit planner assumption (surfaced, never silently dropped)
Rows are REPLACED (not appended) on a probe re-run — idempotent. -->

## FED-05 Visual Anchor
Primary visual anchor: the trusted-nodes list (federation trust is the primary path); meshed-lightning-peers list second; manual-paste fallback visually de-emphasized below both (collapsed behind the "Paste URI Manually" entry point per the Copywriting Contract above, not rendered as a third equal-weight column).
---
## FED-06 Sizing Decision (resolves RESEARCH.md Pitfall 4 / Assumption A4)
RESEARCH.md flagged the `ScreensaverRing` size mismatch (`compact` = 240–320px vs. the current 96–112px paid-tick badges) as needing a UI-spec decision before implementation. **Decision: add a new `badge` size variant to `ScreensaverRing.vue`**, not a CSS `transform: scale()` wrapper — cleaner, reusable across both call sites, and avoids reduced-motion/layout-box mismatches that a transform hack would introduce.
| Variant | Diameter (mobile) | Diameter (≥768px) | `--viz-radius` | Used by |
|---------|-------------------|--------------------|-----------------|---------|
| `badge` (NEW) | 160px | 192px | 80px / 96px | `SendBitcoinModal.vue` `.send-success-burst` (replaces the 112px burst), `WalletScanModal.vue` `.success-ring` (replaces the 96px/`w-24` ring) |
| `compact` (existing, unchanged) | 240px | 320px | 120px / 160px | `SystemDangerZone.vue` and other existing overlay contexts — do not touch |
| `default` (existing, unchanged) | 280–400px (responsive) | — | 140–200px | Full-screen `Screensaver.vue` |
Composition at both call sites: `<ScreensaverRing size="badge" />` renders the radiating EQ segments; the existing `.burst-core` (green circle + checkmark, `SendBitcoinModal.vue`) or `.success-ring` inner content (`WalletScanModal.vue`) is layered centered on top via `position: absolute; inset: 0` within a shared `position: relative` wrapper sized to the `badge` diameter — same layering pattern `Screensaver.vue` already uses for `ScreensaverLogo` inside `ScreensaverRing`. Do not resize or restyle the checkmark/core itself; only its container changes from a bespoke 96–112px circle to the `badge`-sized wrapper.

# Phase 1 — Validation Strategy
> Per-phase validation contract for feedback sampling during execution.
---
## Test Infrastructure
| Property | Value |
|----------|-------|
| **Framework** | cargo test (Rust, workspace at core/) + bash harnesses (tests/multinode/, tests/lifecycle/) + node --check / manual curl for mock-backend |
| **Config file** | core/Cargo.toml (workspace); tests/multinode/smoke.sh |
| **Quick run command** | `cd core && cargo test -p archipelago federation` |
| **Full suite command** | `cd core && cargo test` (plus on-node `tests/multinode/smoke.sh` for cross-node behavior) |
| **Estimated runtime** | ~120 seconds (cargo test); multinode smoke is node-gated |
|
---
## Sampling Rate
- **After every task commit:** Run `cd core && cargo test -p archipelago federation` (or the targeted module's tests)
- **After every plan wave:** Run `cd core && cargo test`; frontend waves: `cd neode-ui && npm run build` + grep dist for new strings
- **Before `/gsd-verify-work`:** Full suite green + multinode smoke considerations noted (cross-node checks are hardware/node-gated)
- **Max feedback latency:** 180 seconds

## Wave 0 Requirements
- [ ] Storage-race unit tests for `federation/storage.rs` (concurrent load/save + remove-during-sync) — stubs for FED-01/FED-02
- [ ] Mock-backend RPC parity checks (mesh contacts + message-mutation methods) — FED-04 remainder
*Existing infrastructure covers cargo test; multinode smoke.sh covers cross-node sync but runs on-node only.*

## Manual-Only Verifications
| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Removed peer never reappears across real fleet sync cycles | FED-01 | Needs two live nodes + wall-clock sync cycles | Remove a peer on archi-dev, watch peer list through ≥2 sync cycles (90s loop), confirm absent + error surfaced on induced failure |
| Channel-open UX end-to-end | FED-05 | Visual/UX judgment + live LND | Drive :8100 preview against archi-dev; share URI, open channel to trusted node, request public-node channel |
| Paid-tick animation on-brand | FED-06 | Visual judgment | Trigger payment success in preview; compare ring/EQ segments to screensaver |
