Scope `"once"` is in-memory only; `"always"` rows persist. + +4. **Inline AUTH banner UX** (desktop only — Android inherits classification, separate UI pass later): + - Add `AccountAuthApprovals` ViewModel exposing `MutableStateFlow>`. + - In `ChatPane` (the right pane of `DesktopMessagesScreen`), render an inline banner above the message list when an approval is pending: `" requires authentication to deliver this message. [Once] [Always] [Never]"`. + - `[Once]` → grants for the current session, no persistence. `[Always]` → writes `auth_approvals(scope="always")`. `[Never]` → writes `auth_approvals(scope="blocked")`, drops the wrap. + - **Survey precedent**: check current behavior in Coracle, Damus, Primal, 0xchat before final mockup (open question Q5 in brainstorm). + +5. **Re-subscribe to kind:1059 on `authCompleted`** (R3): + - Wire `RelayAuthenticator.checkAuthResults` to emit `authCompleted(relayUrl)` after a successful AUTH-OK. + - The desktop `DesktopRelaySubscriptionsCoordinator` already calls `syncFilters` indirectly via outbox sync. Verify the kind:1059 REQ is re-sent on that relay specifically.

Marmot already in tree (per `quartz/.../marmot/`). Separate track.

Better path is to make bunker fast (Phase 6) than to drop it. | +| **Per-relay outbox max-tries config without auth-required carve-out** | Half-measure; doesn't solve the silent-drop case where AUTH succeeds AFTER 3 retries exhausted. The carve-out is required regardless. | +| **In-memory only retry queue** | Loses messages on app crash / kill.

Alternative: archive to `retry_queue_dead_letter` table for diagnostics. +2. **AUTH-approvals table must be account-scoped.** Multi-account users share the SQLite store across accounts but each row carries `account_pubkey`. Test: account A approves relay X "always"; account B sending to relay X gets tier-2 prompt independently. +3. **Indexer cache invalidation.** If recipient publishes a new 10050, our 1h TTL hides it. Mitigation: on receiving a fresh kind:10050 event for any user via the normal relay feed, eagerly update the cache. +4. **Self-copy wrap can race the original.** If self-copy lands first, recipient #1's wrap arrives second and we already have the rumor — dedupe at rumor.id should handle it. Test. +5. **Retry queue + AUTH banner can dual-drive UI** — if a wrap is queued AND the relay's AUTH is pending, we don't want two notifications. Coordinator suppresses retry attempts on relays in `AUTHENTICATING` state. +6. **Conversation-key cache (Phase 6) lives in memory only.** On logout / account switch, must wipe to prevent cross-account leakage. + +### API Surface Parity + +| Surface | Effect | +|---|---| +| Desktop NIP-17 send | full plan | +| Android NIP-17 send | inherits all `commons/` + `quartz/` changes. Android-specific UI (AUTH banner) NOT in this plan — separate Android pass.

Tier-2 AUTH approvals via a config file (out of scope, file follow-up). | +| Marmot/MLS DMs | unaffected (separate event kinds + path) | +| NIP-04 legacy DMs | unaffected (no AUTH retry, no retry queue — legacy path stays as-is per brainstorm Q1) | + +### Integration Test Scenarios + +1. **AUTH retry across restart.** Send DM to relay R that demands AUTH. Sign + send AUTH. Kill app before AUTH-OK arrives. Restart. Verify retry queue resumes, AUTH handshake completes, original wrap accepted. +2. **Tier-2 prompt persistence.** Recipient has 10050 pointing to a relay user has never seen. Send → banner appears → user clicks `[Always]`. Send another DM to same recipient → no banner; relay AUTH'd silently using stored approval. +3. **No-10050 security path.** Recipient has no kind:10050 in our cache and on indexers. Send → dialog shows "Enter manually". Cancel → zero outbound traffic to general relays. Verify via mock-relay sniffer. +4. **Bunker batch RPC inbox load.** 200-wrap inbox, bunker user. Pre-plan: ~200 round-trips (~minutes). Post-plan with capability: ≤2 round-trips (~seconds). Measured via signer-call counter. +5. **Group DM rumor coherence.** Send to [A, B, C]. Each receives a wrap. A reacts to message → reaction `e` tag references shared `rumorId`. B and C see the reaction associated with the right message. Sender sees it too. +6. **Self-copy cross-device.** Account on desktop install X sends DM to recipient. Open same account on install Y (cold cache). Y's first 10050 fetch returns sender's own DM relays → self-copy wrap arrives → conversation pre-populates. +7. **Window-focus re-AUTH.** Mac sleeps 1h.
