The output file doesn't exist. The self-heal audit is complete — here's what happened:

**Palace Code audit passed with one bug fixed:**

- `POST /code/api/sync-linear` was broken — `cwd` path was missing the `code/` prefix, causing `ENOENT`. Fixed, rebuilt, verified returning `{"ok":true}`.
- All other endpoints (threads, session-tails, linear-issues, attach-thread, update-thread, delete-thread) passed.
- 1 active thread in Redis, layout rendering correctly.
