# TASKS

Use this board to coordinate handoff between planner, implementer, and reviewer.

Status values:
- `in_planning`
- `ready_for_implement`
- `in_implementation`
- `ready_for_review`
- `in_review`
- `ready_to_commit`
- `changes_requested`
- `done`

Command expectations:
- planner moves tasks into `in_planning` and `ready_for_implement`
- implementer moves tasks into `in_implementation`, `ready_for_review`, and `done`, and resumes work from `changes_requested` and `ready_to_commit`
- reviewer moves tasks into `in_review`, `ready_to_commit`, or `changes_requested`
- `status_cycle` should report deterministic task status, current owner role, and next recommended action based on this board

| Task ID | Scope | Status | Acceptance Criteria | Evidence | Next Role |
| --- | --- | --- | --- | --- | --- |
| T-001 | FastAPI backend (`app.py`) + inline HTML/JS frontend (`requirements.txt`) | done | `GET /` returns 200 with HTML containing "Download MP3"; `POST /download` with valid URL + mode streams a file; invalid URL returns 400 JSON with `.message` | Reviewer re-ran mocked FastAPI route checks (GET /, valid download, invalid/empty/missing-field errors, yt-dlp failure, unicode filename) — all passed; see `.ai/REVIEW.md` | none |
| T-002 | Dockerfile + README.md (build/run docs) | done | `docker build -t yt-dl .` exits 0; `docker run --rm -p 8080:8080 yt-dl` starts server; `curl http://localhost:8080/` returns HTML with download buttons | Reviewer re-ran `docker build` + container smoke test, plus a live end-to-end MP3 and video download against a real YouTube URL through the container — all passed; see `.ai/REVIEW.md` | none |
| T-003 | `app.py` (`noplaylist` option, `sanitize_filename` helper, title-based `FileResponse` filename, frontend `Content-Disposition`-based `link.download` fix) + `README.md` update | done | Pasting a playlist/`list=` URL downloads only the referenced video; saved filename matches the video title with emoji/icons stripped (normal chars kept) instead of a UUID, with correct extension; `python -m py_compile app.py` passes | Reviewer re-ran `py_compile`, unit-checked `sanitize_filename`, and ran a live end-to-end playlist-link MP3 download + a plain video download through the built Docker image against real YouTube URLs — all passed; see `.ai/REVIEW.md` | none |
| T-004 | `app.py` (job-based `POST /download` + `GET /progress/{job_id}` + `GET /download/{job_id}/file`, in-memory job store, yt-dlp `progress_hooks`, frontend polling + progress bar UI) + `README.md` update | done | Progress bar appears below the buttons on download start and updates with percent/speed/downloaded-total size; file auto-delivers to the browser on completion with the correct sanitized filename; server-side failure shows an error in place of the bar with no crash; `python -m py_compile app.py` passes | Reviewer re-ran `py_compile` and drove the full job lifecycle live through the built Docker image against real YouTube URLs (progress polling, auto-delivered file, 404/409 semantics, server-side error path with no crash) — all passed; see `.ai/REVIEW.md` | none |
