Two unbounded per-session leaks that never released after a workflow ended:
- SessionOrchestrator.artifactContentCache (full file contents, keyed
"<sessionId>:<path>") grew for the process lifetime. Added
evictArtifactContentCache(sessionId) — session-prefix key removal,
rehydrate-safe — called on both completeWorkflow and failWorkflow.
cancellations was already evicted on both terminal paths.
- NarrationSubscriber leaked a Channel + worker coroutine + lanes map entry
per session forever. closeLane() now closes the lane channel on
WorkflowCompleted/WorkflowFailed (draining the terminal narration first);
the worker self-removes from lanes when its for-loop exits on close.
Deferred: SqliteEventStore.subscriptions eviction — removing the SharedFlow
mid-life would strand LiveArtifactRepository's downstream collector (a
suspended-coroutine leak worse than the tiny empty-SharedFlow entry).
Green: :core:kernel compile+detekt, :apps:server *NarrationSubscriber* (8).
