feat(supervise): event bus priority bump + A++ observability#317
Merged
Conversation
Upgrade the child→parent bus from FIFO to the real coordination core: - PRIORITY pull — a blocking question (urgency→priority: blocks-run=20, blocks-step=10) bumps ahead of queued settles/findings so the driver sees it first; ties FIFO by seq. Pass-through (subscribe/onEvent) still delivers immediately. - Observability A++ — every event stamped (seq/at/priority); history() is the full ordered audit/replay trail; stats() counts published/pulled/by-kind. Surfaced on CoordinationTools and the serveCoordinationMcp handle. - Generalized questions — ask_parent questions are bus events carrying urgency-derived priority; peek() + unsubscribe round out the primitive. bus 6 + coordination 10 tests; full suite 999 pass; typecheck/build/lint clean.

Upgrades the child→parent coordination bus (#316) from FIFO into the real core that backs ~all supervisor↔worker interactions.
What changed
blocks-run=20,blocks-step=10) is pulled ahead of queued settles/findings so the driver sees it first; ties resolve FIFO byseq. Pass-through (subscribe/onEvent) still delivers the instant it's raised.seq/at/priority);history()is the full ordered audit/replay trail;stats()counts published/pulled/by-kind. Surfaced onCoordinationToolsand theserveCoordinationMcphandle.ask_parentquestions are now bus events carrying urgency-derived priority — one mechanism, not a side channel.peek()+ unsubscribe round out the primitive.Why
One typed node↔node primitive: settled / question / finding are all events; new interaction kinds are additive; the in-process queue and a future cross-box durable mailbox share the same interface.
