-- GChat: fix float startIndex in annotation parsing
-- Postgres: atomic lock upsert to eliminate TOCTOU race
-- Coverage tests added for 4 low-coverage modules
-- Documentation updates (TESTING.md, ARCHITECTURE.md)
+- **3,106 tests**, all passing
+- Chat orchestrator: 96% of TS (concurrency, lock conflict, slash commands)
+- Thread: 137% of TS (streaming, pagination, ephemeral, scheduling)
+- Channel: 144% of TS (state, threads, metadata, serialization)
+- Markdown: 126% of TS (node builders, round-trips, type guards)
+- Integration: 94% of TS (recorded fixture replays for all platforms)
+- All 8 adapters: 100%+ of TS test count
