+### Removed
+
+- work-loop: removed the manual C3 ratification gate check and its `skills/work-loop/AGENTS.md` (#7226). The check can only run on a GitHub tracker, because it needs comment authorship and label provenance that the local-markdown adapter does not provide. The work-loop `SKILL.md` no longer points at the check.

-## Manual check for the C3 ratification gate
-
-There is no automated test surface for this LLM-executed gate. After editing the admission gate in
-`SKILL.md` or `reference/c3-ratification-queue.md`, re-run the gate against an item whose body
-carries the ratification phrase and which a "Superseded" comment already restored to the frontier
-once after a wrong re-queue. Confirm the item ends the cycle carrying the human-gated role label
-with exactly one `kind=ratify-c3` comment, visible as a `[ratify]` row in `/work-items:attend-queue`,
-and that no second queue comment was posted.
