+# Task State Attached Repo Impact
+
+Date: 2026-05-25
+Interface change: `649102a2-4373-4621-9848-cc257e67c262`
+Status: published
+
+## Notice Channel
+
+State Hub published a breaking schema interface change from `state-hub` to all
+active attached repos except `state-hub` itself.
+
+The notice points target repos to `docs/task-state-canon-migration.md` and asks
+their local agents to update any State Hub task-status references:
+
+```text
+blocked -> wait
+in_progress -> progress
+cancelled/canceled -> cancel
+todo -> todo
+done -> done
+```
+
+Workstream/workplan lifecycle status is unchanged and still includes
+`blocked`.
+
+## Classification
+
+Classification was based on `GET /repos/` plus a read-only local scan of active
+repo paths. `legacy-literals` means a repo contains old words such as
+`blocked`, `in_progress`, `cancelled`, `blocked_tasks`, or `TaskStatus`; the
+hit can be task state, workstream state, capability/debt status, or prose, so
+the owning repo agent must review context before editing.

+## Requested Repo-Agent Action
+
+Each repo agent should:
+
+1. Read its State Hub inbox notice for interface change
+   `649102a2-4373-4621-9848-cc257e67c262`.
+2. Search local agent instructions, workplans, scripts, docs, tests,
+   dashboards, and API clients for State Hub task-status values.
+3. Replace task-state usage with canonical values and leave unrelated
+   workstream/capability/debt statuses unchanged.
+4. Report completion by replying in State Hub or resolving the interface change
+   for that repo once local adaptation is complete.
