docs(matrix): LAB-519 ts stampede/backpressure cells + LAB-427 staleness fix#38
Merged
Conversation
…(LAB-519) Cold-miss single-flight (always on) + opt-in LockableBackend wiring land in cachekit-ts#77 — the ts stampede cell moves from refresh-path-only to full, and distributed locking is now actually called from the live cache path instead of being an unwired capability. Records the LAB-519 backpressure decision: no general miss cap beyond maxConcurrentRefreshes (event-loop model; rationale in the note under the Reliability table). Also refreshes the ts Redis lock/TTL capability cells that went stale when LAB-427 (ts#74) shipped RedisBackend as LockableBackend + TTLBackend without touching the matrix.
