Two event-delivery back-pressure faults from the core audit (#7).
(a) streamGlobal forwarded globalFlow → a per-connection Channel with
buffer.send (SUSPEND). globalFlow is also SUSPEND-overflow, so one wedged
WebSocket client back-pressured globalFlow → append() suspended → the whole
kernel stalled. Now the collector uses trySend; on overflow it closes the
buffer with SlowClientException, tearing down that one connection (client
reconnects and re-syncs via replaySnapshot) instead of blocking append().
(b) Per-session subscriptions (extraBufferCapacity 64) used tryEmit with the
return ignored: a lagging in-process collector (e.g. LiveArtifactRepository)
silently diverged from the durable log. Both SqliteEventStore and
InMemoryEventStore now warnIfDropped() — the event is still persisted; only the
live SharedFlow drops, and we surface it. ponytail: log-only; bounded
rebuild-on-lag if divergence ever bites.
Added slf4j-api to :infrastructure:persistence (already the standard logging
dep across modules) for the warn.
Green: :infrastructure:persistence + :apps:server compile+detekt+test (the one
pre-existing ModelLifecycleWiringTest failure needs a real llama-server, fails
identically on clean checkout).
