| Field | Value |
|-------|-------|
| Agent | claude |
| Summary | Planned Priority 3 fix for downloads failing with a false "This video is not available" error caused by yt-dlp having no JS runtime in the container: install Deno in the Dockerfile and point yt-dlp's `ydl_opts` at it explicitly, plus a README note on the new dependency. |
| Files Changed | ROADMAP.md, .ai/PLAN.md, .ai/TASKS.md |

| Field | Value |
|-------|-------|
| Agent | claude |
| Summary | Reviewed and verified the Deno JS runtime fix: rebuilt the Docker image, confirmed the `js_runtimes`/`remote_components` `ydl_opts` shape against the installed yt-dlp source, and drove live MP3 downloads (previously-failing URL + a playlist-link regression check) through the container with no missing-runtime warning and the EJS solver actively used. |

### T-006 — plan — 2026-09-11T13:33:14Z

| Field | Value |
|-------|-------|
| Agent | claude |
| Summary | Planned Priority 4 fix for PO-Token/429 download failures: add `extractor_args.youtube.player_client` ordering (android/ios/tv before web) to the shared `ydl_opts` in `app.py` so extraction avoids the web client's PO Token requirement first. |
| Files Changed | ROADMAP.md, .ai/PLAN.md, .ai/TASKS.md |
| Next Role | implement |

### T-007 — plan — 2026-09-11T13:33:14Z

| Summary | Planned Priority 5 feature: add a third "Download Video 720p" mode/button, capped at 720p via `bestvideo[height<=720]+bestaudio/best[height<=720]` with graceful fallback to lower quality, reusing existing progress/filename/playlist behavior. |
| Files Changed | ROADMAP.md, .ai/PLAN.md, .ai/TASKS.md |
| Next Role | implement |

### T-006 — implement — 2026-09-11T13:36:04Z

| Field | Value |
|-------|-------|
| Agent | codex |
| Summary | Configured yt-dlp to prefer Android, iOS, and TV player clients before web, avoiding the web client's PO-token failure path. |
| Files Changed | app.py, README.md, ROADMAP.md, .ai/PLAN.md, .ai/TASKS.md, .ai/HANDOFF.md |
| Validation | `python3 -m py_compile app.py`, `docker build -t yt-dl .`, and a live MP3 job for `https://www.youtube.com/watch?v=LV-NXucnyrc` passed; alternate clients were used after a web 429 and the file was delivered. |
| Commit | Pending reviewer approval |
| Next Role | review |

| Field | Value |
|-------|-------|
| Agent | claude |
| Summary | Reviewed and verified the player-client ordering fix: rebuilt the Docker image, confirmed `player_client` is genuinely consumed by the installed yt-dlp extractor, and drove live downloads (previously-failing `LV-NXucnyrc`, plain MP3/Video, playlist-link, error-path) through the container — no PO-Token-blocking failure, alternate clients used after a web 429, all regressions passed. |
| Files Changed | .ai/TASKS.md, .ai/REVIEW.md, .ai/HANDOFF.md |
| Verdict | PASS |
| Blocking Findings | none |
