# Requirements: Archipelago (v1.8.0 — Developer-Ready App Platform)

**Defined:** 2026-07-29
**Core Value:** A third-party developer can publish an app via the signed/decentralized registry and a user can install it on their node — manifest-driven, rootless, secure, robust.

No PRDs existed in the ingest set; these requirements are derived from the master plan's
declared exit criteria (multinode pass + workstreams B/C/F), `.planning/codebase/CONCERNS.md`,
`docs/UNIFIED-TASK-TRACKER.md`, and the user-chosen success metric. Constraints from
`docs/app-manifest-spec.md` and the locked ADRs (see PROJECT.md) bound how each is built.

## v1 Requirements

### Federation & Mesh Hardening (FED)

- [ ] **FED-01**: Removing a federation node sticks — it disappears from every UI surface, tombstones propagate, it never reappears via later sync cycles, and a failed removal surfaces an error (never a silent no-op)
- [ ] **FED-02**: Federation sync converges and is observable — after sync settles, fleet nodes agree on the node list with fresh status; stale entries, duplicates, and silent sync failures are eliminated and sync errors are operator-visible
- [ ] **FED-03**: A structured code review of the federation/fleet area (`core/archipelago/src/federation`, node sync, FIPS/transport dial layer) and mesh area (`core/archipelago/src/mesh`, mesh RPC surface) is completed, with every finding fixed or explicitly deferred with a reason
- [ ] **FED-04**: Mesh messaging parity — attachment send (and the rest of the mesh chat surface) behaves identically on the demo and on real nodes: the demo backend implements the same RPC surface the UI calls, transport decisions mirror the real size-based tier logic, and no demo-only modals exist
- [ ] **FED-05**: Inter-node Lightning channel opening UX — the UI shows the node's shareable Lightning URI; lists trusted (federated) nodes by hostname for one-click channel opening; and lets the user browse/request channels with public nodes — using the existing design system and components, verified on the :8100 dev preview against archi-dev before deploy
- [ ] **FED-06**: On-brand payment success animation — the invoice "paid" tick's circle uses the screensaver-style ring with outer EQ-segment lines (reuse `ScreensaverRing.vue`'s compact size) in place of the current success burst, applied consistently everywhere the paid tick shows

### UI Performance (PERF)

- [ ] **PERF-01**: The slowest tab switches and secondary-screen opens are profiled with causes named (remount storms, serial RPC waterfalls, uncached fetches) — fixes are targeted, not guessed
- [ ] **PERF-02**: Main-tab switches render immediately from cached state with background refresh — no blank screens or long spinners on tabs already visited this session
- [ ] **PERF-03**: Secondary screens (screens reached from a tab's main page) open without a blocking full reload and are instant on repeat visits — verified on real node hardware, not just the dev box

### Multinode Verification (MNODE)

- [ ] **MNODE-01**: The 5× destructive lifecycle gate passes on a second fleet node (archy-x250-beta) with 0 failures, run on-node per gate policy
- [ ] **MNODE-02**: Cross-node federation/mesh/transport suites (`tests/multinode/smoke.sh`, `meshtastic.sh`) pass between fleet nodes, with all harness RPC calls time-bounded (no indefinite curl hangs)
- [ ] **MNODE-03**: Removing a federation peer sticks — tombstone-write failures are surfaced (not swallowed) and a removed peer never silently reappears after subsequent sync cycles

### Lifecycle Perfection (LIFE)

- [ ] **LIFE-01**: Quadlet backends are the default — restarting `archipelago.service` leaves every app container running (no SIGKILL-the-world, no multi-minute rebuild storm)
- [ ] **LIFE-02**: The reconciler self-heals failed Quadlet units — a `.service` in `failed` state (and not user-stopped) is reset-failed + started automatically, with backoff against busy-looping
- [ ] **LIFE-03**: Per-app restart/flap observability — restart counters, a threshold log line when an app restarts >N times in M minutes, and restart counts surfaced in health/status RPC output
- [ ] **LIFE-04**: Cascade uninstall→reinstall is gate-verified for multi-container stacks and installed apps — no ghost entries, no orphan containers, data preserved per policy, reinstall returns healthy
- [ ] **LIFE-05**: Install and uninstall report real, monotonic progress driven by backend progress events, always reaching a terminal success/failure state — asserted in the gate, never a fake or stuck bar

### Registry-Distributed Manifests (REG)

- [ ] **REG-01**: The published signed catalog embeds full app manifests; nodes install/update from signature-verified catalog manifests (disk manifests remain the fallback for build-source apps); tampered catalogs are rejected with safe fallback
- [ ] **REG-02**: The fleet is flipped to registry-distributed manifests — adding or bumping an image-only app requires only a re-signed catalog publish, no binary OTA or disk rsync

### Security Enforcement (SEC)

- [ ] **SEC-01**: `AppManifest::validate()` enforces the full ADR-009 mandate set — non-root UID, pinned image tags (no `latest`), capability allow-list, seccomp — with explicit, documented, auditable overrides
- [ ] **SEC-02**: Generated AppArmor/seccomp security profiles are actually applied at container creation (`--security-opt`) and verified effective on running apps

### Developer Tooling (DEV)

- [ ] **DEV-01**: `archy app validate` checks a manifest locally and returns the same pass/fail verdict the node enforces (schema + security rules)
- [ ] **DEV-02**: `archy app render` previews the exact Quadlet/podman configuration a manifest produces
- [ ] **DEV-03**: A developer can local-install and lifecycle-test an app against a dev node from the CLI (`archy app local-install` / `lifecycle-test`)
- [ ] **DEV-04**: The developer guide walks a new third-party developer from an empty directory to an installed, running app using only the CLI and docs

### Decentralized Marketplace (MKT)

- [ ] **MKT-01**: A third-party developer can publish a DID-signed app manifest to public Nostr relays (NIP-78, kind 30078) via the tooling
- [ ] **MKT-02**: A node discovers marketplace apps from multiple relays and displays each app's trust tier (Verified / Community / Unverified) per ADR-006 trust scoring
- [ ] **MKT-03**: Manifest signatures are verified before installation; tampered or invalid marketplace manifests cannot be installed
- [ ] **MKT-04**: End-to-end north star: a user installs a third-party marketplace-published app on their node and it runs healthy under the standard lifecycle guarantees

## v2 Requirements

Deferred to a future milestone. Tracked but not in the current roadmap.

### Distribution Backbone (DIST)

- **DIST-01**: BLAKE3 content-addressed catalog distribution via iroh swarm, origin-always-wins (workstream D — design-only today, tracker-marked backlog)

### Fleet & Hardening (FLEET)

- **FLEET-01**: Bitcoin multi-version fleet-wide OTA rollout (user-gated on timing per `docs/bitcoin-version-bulletproof-rollout.md`)
- **FLEET-02**: App-specific health assertions for the ~34 apps with only baseline lifecycle coverage
- **FLEET-03**: LUKS2 full-partition encryption for `/var/lib/archipelago/`
- **FLEET-04**: Dynamic per-app resource rebalancing (cgroup-stats feedback loop)

## Out of Scope

| Feature | Reason |
|---------|--------|
| Rootful/privileged containers, Docker | Invariant — ADR-001/ADR-009 |
| Per-app Rust installers / host provisioning | The anti-pattern workstream A deleted |
| Centralized gatekept app store | ADR-006 chose decentralized Nostr marketplace |
| Web5 DWN spec compliance | ADR-011 — deprioritized after TBD shutdown |
| Custom live voice-call protocol | Deprioritized 2026-07-01 per user; no scope decided |
