+# Orch Council Wait
+
+## Status
+
+- `completed`
+
+## Owner
+
+- codex
+
+## Started At
+
+- `2026-03-19`
+
+## Goal
+
+- implement `orch council wait` so the leader can block until all three reviewer tasks finish or a timeout is reached
+
+## Scope
+
+- add council wait status queries and blocking wait behavior on top of existing council reviewer rows
+- add CLI support for `orch council wait`
+- add integration tests for wake and timeout behavior
+- update the implementation roadmap and archive this workstream when complete
+
+## Checklist
+
+- [x] inspect council wait docs and current council storage
+- [x] implement council wait store and CLI command
+- [x] add integration coverage for council wait wake and timeout
+- [x] run `go test ./...`
+- [x] update `docs/implementation-roadmap.md`
+- [x] archive this roadmap with a completion summary

+
+## Decisions
+
+- treat reviewer completion as all council reviewer tasks reaching terminal task states
+- reuse the existing `orch wait`/reconcile polling model rather than introducing a separate push mechanism for councils
+
+## Blockers
+
+- none
+
+## Next Step
+
+- implement `orch council tally` by parsing completed reviewer outputs into `council_findings` and grouping similar proposals
+
+## Completion Summary
+
+- `orch council wait` now blocks until all council reviewer tasks reach terminal task states or a timeout is reached
+- wait responses return reviewer task statuses on both wake and timeout paths
+- integration tests now cover council wait wake and timeout behavior
