Refresh an app verify skill

Leading words: source then live, proven corrections, never product code.

Upkeep for a skill from generating-app-verify. The unit is the feature, not every sentence.

Copy these steps into the todo list verbatim. Skip with skip: <reason>.

1. Locate skills/verify-*/ (or the project's verify skill). None → stop and point at generating-app-verify.
2. Index hygiene on the feature-map README.
3. Source wave: one read-only subagent per feature file. Children never drive or edit.
4. Reconcile recipes. Flag user-facing surfaces missing from the map only with a source path.
5. Live pass: exercise every feature at least once. Doctor before first drive and after failed drives. Evidence survives cleanup.
6. Triage: map drift → fix the map. Harness gap → fix harness. App broken → report, do not paper over.
7. Outcome: clean (no PR) / changed (one PR of proven corrections) / blocked (say what blocked).
