+  | MCP | *"Append an update note to a task **without changing status**"* → `POST /api/v1/tasks/:podId/:taskId/updates`, params `{podId, taskId, text, priority?, prUrl?, continueAnyway?}`; optional `prUrl` first PATCHes the task URL | no — the PATCH wrapper exposes `prUrl` only, not `title` |

   The backend is not the constraint. `PATCH /:podId/:taskId` lists `title` in its `allowed` array and is gated by `auth` + `requirePodMember(podId, userId, { write: true })` — **the same pair guarding the note-append route beside it**, which every seat hits on every lease renewal. So the authority is identical and only the tool surface differs.
