## ▶️ RESUME HERE — archy↔archy LoRa (2026-06-30 PM) — READ FIRST

**Goal:** archy↔archy text over Meshtastic LoRa must DELIVER and show the E2E pill,
identical in off-grid and normal mode. Test bed = `.116` / `.198` / `.228` (all EU_868).
Don't touch the federation/FIPS path.

### TL;DR of where we are
The **archy software is correct and deployed.** The blocker is now PROVEN to be at the
**radio/RF layer: the three radios are not hearing each other over the air at all.** No
amount of archy code change will fix that until the radios actually RF-link. **Resume by
testing the radios directly at home (Meshtastic phone app over Bluetooth) — see "DO THIS
FIRST AT HOME" below.**

### What is DONE and deployed (commit pending — see below)
- **E2E send fix** (`core/archipelago/src/mesh/mod.rs` `send_message`, ~L1542): archy↔archy
  plain chat text is now sent as a **native `TEXT_MESSAGE_APP` DM** (firmware PKC-encrypts
  it E2E), NOT wrapped in our binary typed envelope. Archy peers' Sent rows are marked
  `encrypted=true` so the pill shows. Rich typed msgs still use `send_typed_wire`. This was
  the original root-cause fix (envelope-wrapped text silently broke archy↔archy LoRa).
- **NEW: software radio-reboot** end-to-end, so a wedged/RX-deaf radio can be rebooted
  without physical access (and for the Device-tab settings panel the user requested):
  - `meshtastic.rs`: `reboot(seconds)` driver method + `ADMIN_REBOOT_SECONDS_FIELD = 97`
    (verified vs meshtastic/protobufs admin.proto — `set_owner=32/set_channel=33/set_config=34`
    matched our existing constants, confirming the proto read).
  - `listener/mod.rs`: `MeshCommand::RebootRadio { seconds }`.
  - `listener/session.rs`: device-enum `reboot()` dispatch (Meshtastic only) + handler arm.
  - `mesh/mod.rs`: `MeshService::reboot_radio(seconds)`.
  - `api/rpc/mesh/messaging.rs`: `handle_mesh_reboot_radio` → RPC **`mesh.reboot-radio`**
    `{seconds?}` (default 2); dispatcher arm in `api/rpc/dispatcher.rs`.
  - `cargo check` passes. Built release **sha `ba4aed590027690d`** and DEPLOYED + active on
    `.116/.198/.228`. The RPC works (`{"reboot":true,"seconds":2}`).
  - ⚠️ **Caveat:** when called, archy logged "Sent Meshtastic radio reboot" but the radio did
    **not** visibly reboot afterward (no config re-stream). Either field 97 is still off, or
    newer firmware requires an admin session passkey even over local serial, or the USB serial
    stayed open through the 2s reboot so no reconnect was logged. **Needs on-device verification.**

### The hard evidence (why "nothing works")
- Directed DM tests `.198→.228` AND `.116→.228` (neither path reflashed): sender logs
  `Sent plain native DM dest=30d258436d65 part=1 total=1` and RPC returns `sent:true,
  encrypted:true`, but `.228` logs **nothing** — packet never reaches archy from the radio.
- A raw broadcast from `.198` (`mesh.broadcast`) was accepted by its radio but **not heard**
  by `.228`/`.116`.
- In an 8-minute window, **all three nodes received 0 inbound OTA packets from any other node.**
  Each only logs its OWN once-a-minute `Broadcast Meshtastic NodeInfo advert` + local TX
  `field=11` queue-status. `.228 mesh.status` = `messages_received:1` total.
- `.198`'s radio is alive and transmitting NodeInfo every 60s — so it's not dead; it's that
  **reception is broken on the receivers.** A radio cannot drop a broadcast AND a unicast to
  its own node number while config matches, unless it simply isn't on the same airwaves.
- archy provisioning is correct & identical across nodes (read back from device): PRIMARY =
  public LongFast (`name="" psk_len=1`), SECONDARY = `archipelago`, region=3 (EU_868). Admin
  field constants verified. The send path hands the radio a correct unicast MeshPacket
  (`to`=node, want_ack, hop_limit=3, plaintext `decoded` for the firmware to PKC-encrypt).

### PRIME SUSPECT (software-fixable) — modem-preset / frequency mismatch
archy only ever writes `region` + `use_preset` and **never explicitly pins `modem_preset`**
(it parses region but not preset; `set_lora_region` relies on the LongFast default). If ANY
radio has a non-default modem preset / frequency slot persisted (e.g. set via the Meshtastic
app, or a different factory default after the `.198` reflash), the radios are on **different
airwaves despite identical channel name + region**, and archy would never correct it.

### DO THIS FIRST AT HOME (decisive, ~2 min, only the user can do it)
Open the **Meshtastic phone app over Bluetooth** (works alongside archy's USB serial) on each
of `.116/.198/.228` and check:
1. Do the 3 nodes **see each other** in the node list (recent "heard")? → if NO, they're not
   RF-reaching (preset/freq/antenna/range).
2. Do all 3 show the **same** Modem preset (LongFast), Region (EU_868), Frequency slot, and
   the same PRIMARY channel? → any difference = the cause.
This single test separates "archy misconfigures the radios" from "radios physically can't
reach each other."

### THEN — the archy fix to apply (if preset/config differs)
Make archy **authoritatively write the full LoRaConfig** and force re-provision so all radios
converge: in `core/archipelago/src/mesh/meshtastic.rs::set_lora_region` (and its
caller/guard `ensure_lora_region` ~L304), explicitly set `modem_preset = LONG_FAST (0)` as a
field in the LoRaConfig (it's currently omitted/defaulted), and make the startup provision
path rewrite LoRa config when the preset doesn't match, then reboot the radio (use the new
`mesh.reboot-radio`). Also verify the `mesh.reboot-radio` actually reboots the radio
on-device (the caveat above).

### TEST RECIPE (works on each node)
- RPC helper used this session: a node-side `rpc.sh` that logs in (password
  `ThisIsWeb54321@`), grabs the `csrf_token` cookie, echoes it as `X-CSRF-Token`, and POSTs to
  `http://127.0.0.1:5678/rpc/v1`. Recreate it or run archy's RPC directly. Methods:
  `mesh.peers`, `mesh.status`, `mesh.messages`, `mesh.send {contact_id,message}`,
  `mesh.broadcast`, `mesh.reboot-radio {seconds}`.
- **LoRa contact ids:** `.116=1135977788` (prefix `3ca5b543`), `.198=3677050140` (`db2b551c`),
  `.228=1129894448` (prefix `30d25843`), stock `3ccc=1128152268`.
- **Link health check (run on each node):** look for inbound `from=Some("!...")` lines in
  `journalctl -u archipelago` that are NOT the node's own `Broadcast ... NodeInfo advert`. If
  zero across all nodes → RF link is down (the current state).
- **E2E success criteria:** send `.198→.228`, the marker appears in `.228` `mesh.messages` as
  an inbound row with `encrypted:true` / `transport:"lora"`, AND `.116↔.228` likewise.

### DEPLOY / BUILD RECIPE
- Build: from `core/`, `CARGO_TARGET_DIR=/tmp/archy-hotfix-target CARGO_INCREMENTAL=0 cargo
  build --release -p archipelago --bin archipelago`. (If `rust-lld: undefined hidden symbol`,
  it's incremental cache — `CARGO_INCREMENTAL=0` fixes it.)
- SSH key `~/.ssh/archipelago-deploy` is authorized on `.116/.198/.228`. SSH/UI/RPC password
  `ThisIsWeb54321@`. Per node: scp the binary, `sudo systemctl stop archipelago` →
  `kill -9 $(pgrep -x archipelago)` → `install -m0755` to `/usr/local/bin/archipelago` →
  `systemctl start archipelago`. Verify by `sha256sum` match + `systemctl is-active`.
- **Current deployed sha on all 3 = `ba4aed590027690d`** (the reboot-enabled build).

### Fleet state (as of 2026-06-30 PM)
- All 3 nodes on binary `ba4aed59`, active. Off-grid mode currently OFF (`mesh_only:false`).
- `.198` radio was reflashed to factory `firmware-heltec-v3-2.7.26` (recovered from corrupt
  NVS); region EU_868 persists. Its archy identity is NOT re-bound on `.228` (`.228` shows
  `.198` as raw radio "Meshtastic 551c", `arch_pubkey_hex` absent) because `.228` hasn't heard
  `.198`'s identity broadcast — a downstream symptom of the dead RF link, not a separate bug.
- The radios are powered & each transmitting; they are simply not hearing each other.

### Deferred UI (after LoRa works)
- Device-tab **settings panel** (gear/desktop) — host the "Reboot radio" button there; calls
  `mesh.reboot-radio`. Scoping done: add to the Mesh.vue actions row (mirrors Broadcast/Off-Grid
  buttons) + a `rebootRadio()` method in `neode-ui/src/stores/mesh.ts`. See `Mesh.vue` ~L1484
  actions row and `mesh.ts` ~L373 `broadcastIdentity()` pattern.
- Device-onboarding modal (detect plugged-in radio).

Current scope:
- Preserve existing mesh work: E2E indicators, FIPS/Tor transport indicators, typed-message paths, Meshtastic region/channel provisioning, and dirty Meshtastic receive-attempt changes.
- Take over the `3ccc` stock Meshtastic peer bug: LoRa text from `3ccc` to Archipelago `.116` does not surface in `mesh.messages`.
- Keep release-gate fixes already made in this session.

Local gate status so far:
- `cargo test -p archipelago --bin archipelago`: green, 849/849 after Meshtastic fixes.
- `python3 scripts/check-app-catalog-drift.py --release --strict`: green.
- `npm run type-check`: green.

Key changes made so far:
- Added cascade uninstall progress truthfulness assertion to `tests/lifecycle/bats/cascade-uninstall.bats`.
- Fixed release catalog drift filters and regenerated catalog metadata.
- Fixed invalid `apps/fedimint-clientd/manifest.yml` `cpu_limit` schema value.
- Updated stale/tight Rust tests without changing production behavior.

Remaining non-automatable / operational gates:
- Workstream B signing is blocked on the offline `RELEASE_MASTER_MNEMONIC`; code + runbook exist, but the publisher must pin/sign the release-root catalog.
- Phase-3 Quadlet backend rollout is implemented behind `use_quadlet_backends` and default-off. The gate skip-passes until explicitly enabled on a node; flipping it fleet-wide requires a coordinated flag rollout plus backend reinstall/migration verification.
- `.116` read-only `use-quadlet-backends-install.bats`: 6/6 skip-clean; no backend `.container` units, so Phase-3 is not active on that node.
- Release metadata still says `1.7.99-alpha` in `releases/manifest.json`; changelog top is `v1.8.00-alpha`. Cutting an actual 1.8.0 OTA requires an explicit version/manifest update.

Do not discard:
- `core/archipelago/src/mesh/listener/decode.rs`
- `core/archipelago/src/mesh/listener/session.rs`
- `core/archipelago/src/mesh/meshtastic.rs`

3ccc bug current hypothesis:
- The prior attempted Meshtastic fix added a hard stale-packet filter using `rx_time`.
- Stock Meshtastic radios without GPS/RTC can report tiny nonzero epoch values until time sync.
- That would make live `3ccc` packets look older than 10 minutes and get dropped before `mesh.messages`.
- Current patch treats implausibly early `rx_time` values as unknown rather than stale.

.116 live validation after 2026-06-30 hotfix:
- `.116` reachable by SSH; `archipelago` active; `/dev/mesh-radio -> ttyUSB0` attached.
- Current canary deploy is commit `b4531bb4`; backend sha
  `4ab53e539d89679ef664401a9a57996267772fed02327abc2912c3e77543acbf`; frontend bundle
  `index-YOAeJF7w.js` / `Mesh-BSAo88jN.js`.
- `main` pushed to `gitea-vps2`.
- RPC on `.116`:
  - `transport.status` currently reports `mesh_only:false` (off-grid mode is not enabled unless
    the user toggles it).
  - `mesh.status` reports Meshtastic connected: `device_type:"meshtastic"`,
    `self_node_id:1135977788`, `peer_count:13`.
  - Recent `.116` -> `3ccc` sent rows are stored with real 2026 timestamps and `transport:"lora"`.
- UI/backend fixes included in `b4531bb4`:
  - `transportLabel("lora")` displays **LoRa**.
  - mesh sends refetch messages after send so transport pills settle without browser refresh.
  - off-grid mode blocks the mesh-chat FIPS/Tor federation fallback and forces LoRa-only sends;
    banner text is `Tor/FIPS disabled - LoRa only`.
  - empty mesh-chat placeholder opacity reduced.
- Meshtastic diagnostics now identify the remaining blocker:
  - 3ccc NodeInfo is discovered:
    `Meshtastic peer is PKC-capable (NodeInfo public_key) node=1128152268 key_len=32`.
  - Bytes from stock Meshtastic text reach `.116`, but the custom parser rejects the packet:
    `Meshtastic FromRadio.packet did not parse into a decoded MeshPacket len=73 head=0dcc3c3e43153ca5b5432a16df56cbed`.
  - Non-text packets decode and are ignored with port numbers (`portnum=3/4/5`), so the serial
    read path is alive. Resume inside `core/archipelago/src/mesh/meshtastic.rs::parse_mesh_packet`.
- LoRa is therefore **not fully fixed** yet: stock `3ccc` -> `.116` text does not surface in
  `mesh.messages`, and `.116` -> `3ccc` still needs user-visible confirmation in the Meshtastic app.
