* fix(imessage): prevent self-chat dedupe false positives (#47830)
Move echo cache remember() to post-send only, add early return when
inbound message ID doesn't match cached IDs (prevents text-based
false positives in self-chat), and reduce text TTL from 5s to 3s.
Three targeted changes to fix silent user message loss in self-chat:
1. deliver.ts: Remove pre-send remember() call — cache only reflects
successfully-delivered content, not pre-send full text.
2. echo-cache.ts: Skip text fallback when inbound has a valid message ID
that doesn't match any cached outbound ID. In self-chat, sender == target
so scopes collide; a user message with a fresh ID but matching text was
incorrectly dropped as an echo.
3. echo-cache.ts: Reduce text TTL from 5000ms to 3000ms — agent echoes
arrive within 1-2s, 5s was too wide.
Adds self-chat-dedupe.test.ts (7 tests) + updates deliver.test.ts.
BlueBubbles uses a different cache pattern — no changes needed there.
Closes#47830
* review(imessage): strip debug logs, bump echo TTL to 4s (#47830)
Bruce Phase 4 review changes:
- Remove all [IMSG-DEBUG] console.error calls from inbound-processing.ts
and monitor-provider.ts (23 lines, left over from Phase 2 debug deploy)
- Bump SENT_MESSAGE_TEXT_TTL_MS from 3s to 4s in echo-cache.ts to give
~2s margin above the observed 2.2s echo arrival time under load
- Update TTL tests to reflect 4s TTL (expired at 5s, live at 3s)
* fix(imessage): add dedupe comments and canary/compat/TTL tests
* fix(imessage): address review feedback on echo cache, shadowing, and test IDs
* refactor(imessage): hoist inboundMessageId to eliminate duplicate computation (#47830)
* fix(imessage): unify self-chat echo matching
* fix: use inbound guid for self-chat echo matching (#55359) (thanks @rmarr)
