/co:check

Read-only drift detection.

Preconditions

• SPEC.md exists. Colony MCP server running.

Procedure

1. Call spec_read — get rootHash and section shapes.
2. If there's an active change for this repo, call attention_inbox with the user's session id — surface pending handoffs, stalled lanes, and any recent claims by other sessions on SPEC.md#V.* or CHANGE.md#*.
3. Scan §T rows:
   • For any row cited as x (done), check that the cited files exist and the cited commands still succeed (run them with --dry-run where available).
   • For rows with status ~ (wip), list the session_id that claimed them via task_list + task_timeline.
4. Cross-change conflict surface (opt-in with --cross-changes):
   • List all spec lanes via task_list filtered on branch prefix spec/.
   • For each pair of in-flight changes, check whether both touch the same §V/§I/§T id. Report pairs that do.
