 ### Added
+- **Automated Documentation Checker** — New GitHub Actions workflow (`documentation-updater`) that reviews code changes on every push and PR to `main`, identifies missing or outdated documentation, and notifies the responsible author via PR comments or issues.
 - **Speed Profile Selection** - New interactive prompt in `doctor.sh` lets you choose between four speed profiles before running migrations, reverse engineering, or conversion-only:
   - **TURBO** — Low reasoning on ALL files with no exceptions. 65K token ceiling, parallel file conversion (4 workers), 200ms stagger delay. Designed for testing and smoke runs where speed matters more than quality.
   - **FAST** — Low reasoning on most files, medium only on the most complex ones. 32K token cap, parallel conversion (3 workers), 500ms stagger. Good for quick iterations and proof-of-concept runs.
