Some rows (schema drift, cancelled requests, manual status edits) have
customer_approved = NULL instead of the default 'none'. Templates called
.upper() on it blindly, causing a Jinja2 UndefinedError / 500 when the
customer player or admin pages loaded.
Replace all .upper() calls with (value or 'none').upper() and add truthy
checks before rendering the approved choice in status.html and
dashboard.html.
- Replace /audio/<token>/<v>.mp3 with /api/stream/<token>/<v>.mp3.
- Stream bytes from private storage with Accept-Ranges and Content-Range support.
- Keep old /audio route returning 404.
- Update player page JS to use new stream endpoint.
- Refresh app.py module and route docstrings for runtime settings,
MP3 tagging, rate limiting, revision workflow, and admin actions.
- Clarify config.py and models.py comments.
- Update template comments/CSS for dashboard filters, request detail,
player page, and settings page.
- Rewrite README.md with current features, status flow, file layout,
deployment variables, and troubleshooting.
- Refresh REVIEW.md quick-reference.
- Add MAX_REVISIONS to docker-compose.yml environment list.
- Expand requirements.txt comment coverage.
