Per-session live observation for owned sessions only, feeding the upcoming client overlay: - State model: SessionObservation (sessionId/url/action/since/ thumbnailAttachmentId/lastError), one entry per owned session; added on start, removed on stop, cleared on dispose. - Instrumentation: the shared runBsk wrapper begins/ends an action (tool name mapped to a verb) around every model-facing call and tags the child with its session id; action end triggers an immediate thumbnail refresh. - Thumbnail loop: 1.5s cadence while active, 8s idle downclock, x3 failure backoff, silent frame retention on errors; captures run OUTSIDE the instrumentation (no action events, no current-pointer movement) and land in the attachment store by reference. - Interrupt: runner.killFor(tag) kills exactly the tagged in-flight bsk children — chat-Stop-equivalent semantics for the current or a named owned session; foreign ids and the no-in-flight case return false. - Remote seam: dsh 0.1's Typert Remote pipeline and forwarded-event allowlist are closed to out-of-tree packages, so state/events/ interrupt are served over the documented webServer route seam: GET /bsk-observation/state, GET /bsk-observation/events (SSE), POST /bsk-observation/interrupt; routes mount only when a webServer service exists (headless compositions skip them). - Config: observationEnabled (true), thumbnailIntervalMs (1500), idleIntervalMs (8000). Tests (+13, 72 total): state machine + event stream, cadence fast/idle/ backoff, headless no-store silence, observation-traffic isolation, interrupt routing (default/specified/none/foreign), HTTP route handlers, disabled-webServer no-op.
