+# Playlists + Profile Hardening Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** (1) Harden Lidarr profile selection (pick metadata + quality profile by name with env overrides, not by array position). (2) Add YouTube playlist support that downloads each track to its own per-artist folder, via both the CLI and the REST API (one playlist = one job, `done` if ≥1 track succeeds).
+
+**Architecture:** New helpers in the single-file `musicfetch` binary (profile lookup by name; `is_playlist_url`/`expand_playlist`/`download_playlist`/`download_single`; `yt_download`/`act_youtube` return success bools). `server/mf.py` re-exports the new URL helpers; `server/jobs.py` gains callable `done_message` (so a batch can report `N/M`); `server/actions.py` + `server/app.py` route URL/playlist `q` to a download job. Tests import the binary via the existing `server.mf` loader (`musicfetch_core`).
+
+**Tech Stack:** Python 3.10+, stdlib `urllib.parse`, `requests`/`ytmusicapi`/`yt-dlp` (already deps), FastAPI, pytest+monkeypatch. No new deps.
+
+---
+
+## Context for the implementer
+
+Work from `/home/zhering/Documents/musicfetch` on branch `feat/playlists-profiles` (already checked out). The `musicfetch` binary (no `.py` ext) already has, verified at these locations:
+- `get_default_metadata_profile_id()` (line ~447): returns `profiles[0]["id"]` — to be replaced.
+- `add_artist()` (line ~457): payload hardcodes `"qualityProfileId": 1` (line ~466) and calls `get_default_metadata_profile_id()` (line ~467).
+- `yt_download(url_or_query, target_folder, quality, dry_run, hit=None)` (line ~579): builds the yt-dlp cmd, `subprocess.run(cmd)` at the end, returns None. `--no-playlist` is in the cmd.
+- `act_youtube(hit, root, quality, dry_run)` (line ~611): builds `music.youtube` URL + per-first-artist folder, calls `yt_download`, returns None.
+- `run_yt_dlp_get_metadata(url)` (line ~623), `get_artist_from_metadata(meta)` (line ~635), `handle_url(url, root, quality, dry_run)` (line ~644).
+- `is_url(s)` (early), `Hit` dataclass, `_ytm_artists(item)` (in YouTube-search section), module-level `YTMusic` (None if not installed), `subprocess`, `json`, `os`, `requests`, `RequestException`, `dbg`, `err`, `lidarr_get`, `lidarr_post`.
+
+`server/mf.py` re-exports a fixed symbol list + `__all__`; `server/jobs.py` has `run_job(job_id, fn, done_message, fail_message=...)` where `done_message` is currently a str; `server/app.py` `fetch()` treats `q` only as a search term; `server/actions.py` has `perform_fetch`, `started_message`, `done_message`, `failed_message`.
+
+Tests: `import server.mf  # noqa: F401` then `import musicfetch_core as mf`; monkeypatch `mf.lidarr_get`, `mf.act_youtube`, `mf.subprocess`, `mf.YTMusic`, and `monkeypatch.setenv`.
+
+Add to the top imports block of `musicfetch` (Task 2): `from urllib.parse import urlparse, parse_qs`.
+
+---
+
+### Task 1: Lidarr profile hardening
+
+**Files:**
+- Modify: `musicfetch` (replace `get_default_metadata_profile_id`; add `_profile_id_by_name` and `get_quality_profile_id`; change `add_artist` payload)
+- Test: `tests/test_profiles.py`
+
+- [ ] **Step 1: Write the failing test**
+
+Create `tests/test_profiles.py`:
+```python
+import server.mf  # noqa: F401

+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `pytest tests/test_profiles.py -v`
+Expected: FAIL — `AttributeError: ... 'get_quality_profile_id'` and metadata env tests fail.
+
+- [ ] **Step 3: Implement**
+
+In `musicfetch`, replace `get_default_metadata_profile_id` with:
+```python
+def _profile_id_by_name(path: str, env_var: str, default_name: str) -> int:
+    """Return the id of the profile whose name matches env_var (default
+    default_name, case-insensitive). Fall back to the first profile, then 1."""

+    except RequestException as e:
+        dbg(f"{path} fetch failed: {e}")
+        return 1
+    if not profiles:
+        return 1
+    for p in profiles:
+        if p.get("name", "").casefold() == name.casefold():
+            return p["id"]
+    dbg(f"profile '{name}' not found at {path}; using first ('{profiles[0].get('name')}')")
+    return profiles[0]["id"]
+
+
+def get_default_metadata_profile_id() -> int:
+    return _profile_id_by_name("/api/v1/metadataprofile", "LIDARR_METADATA_PROFILE", "Standard")
+
+
+def get_quality_profile_id() -> int:
+    return _profile_id_by_name("/api/v1/qualityprofile", "LIDARR_QUALITY_PROFILE", "Any")
+```
+In `add_artist`, change the payload line `"qualityProfileId": 1,` to:
+```python
+        "qualityProfileId": get_quality_profile_id(),
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `pytest tests/test_profiles.py -v`
+Expected: PASS (6 passed)
+
+- [ ] **Step 5: Commit**

+
+### Task 2: Playlist core in `musicfetch`
+
+**Files:**
+- Modify: `musicfetch` (add `from urllib.parse import urlparse, parse_qs`; add `is_playlist_url`, `_playlist_id`, `expand_playlist`, `download_playlist`, `download_single`; make `yt_download` + `act_youtube` return a success bool; rewrite `handle_url`)

+### Task 3: Re-exports + callable job message
+
+**Files:**
+- Modify: `server/mf.py` (re-export new URL helpers)
+- Modify: `server/jobs.py` (`run_job` accepts a callable `done_message`)
+- Test: `tests/test_jobs.py` (add a callable-message test)
+
+- [ ] **Step 1: Write the failing test**
+
+Append to `tests/test_jobs.py`:
+```python
+def test_run_job_callable_done_message():

+Also add a re-export check — create `tests/test_mf_url_exports.py`:
+```python
+import server.mf as smf

+
+def test_url_helpers_reexported():
+    assert callable(smf.is_url)

+
+Run: `pytest tests/test_jobs.py::test_run_job_callable_done_message tests/test_mf_url_exports.py -v`
+Expected: FAIL (callable message not supported; `smf.is_playlist_url` missing).
+
+- [ ] **Step 3: Implement**
+
+In `server/jobs.py`, inside `run_job`'s `_task`, change the success branch to support a callable:
+```python

+            msg = done_message(result) if callable(done_message) else done_message
+            _touch(job, status="done", result=result, message=msg)
+```
+(Update the `run_job` signature/type hint to `done_message` being `str | Callable[[dict], str]`; import `Callable` is already present.)
+
+In `server/mf.py`, add to the re-export assignments and `__all__`:
+```python
+is_url = _mod.is_url
+is_playlist_url = _mod.is_playlist_url
+download_playlist = _mod.download_playlist
+download_single = _mod.download_single
+```
+Add those four names to the `__all__` list.
+
+- [ ] **Step 4: Run tests to verify they pass**
+
+Run: `pytest tests/test_jobs.py tests/test_mf_url_exports.py -v`
+Expected: PASS.

+- [ ] **Step 5: Commit**
+
+```bash

+- Modify: `server/app.py` (route URL `q` to a download job)
+- Test: `tests/test_api_url.py`

+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `pytest tests/test_api_url.py -v`
+Expected: FAIL (URL `q` currently goes to search → no `download_playlist`/`download_single` calls; kind not "playlist").
+
+- [ ] **Step 3: Implement**
+
+In `server/actions.py`, add:
+```python
+def url_started_message(kind: str, title: str = "") -> str:
+    if kind == "playlist":
+        return (f"Fetching playlist '{title}'. Downloading tracks now."
+                if title else "Fetching playlist. Downloading tracks now.")
+    return f"Fetching '{title}'. Downloading now." if title else "Fetching track. Downloading now."
+
+
+def playlist_done_message(result: dict) -> str:
+    ok, total = result.get("ok", 0), result.get("total", 0)
+    failed = total - ok
+    return f"Downloaded {ok}/{total} tracks" + (f" ({failed} failed)." if failed else ".")
+
+
+def url_done_message(result: dict) -> str:
+    title = result.get("title", "")
+    return f"Downloaded '{title}'." if title else "Download complete."
+
+
+def perform_url_fetch(url: str, quality: str, root: str) -> dict:
+    """Download a URL (playlist → batch, else single). Raises if nothing
+    downloaded so the job is marked failed."""
+    if mf.is_playlist_url(url):
+        ok, total, title = mf.download_playlist(url, root, quality, False)
+        if ok == 0:
+            raise RuntimeError(f"No tracks downloaded from playlist '{title}'." if title
+                               else "No tracks downloaded from playlist.")
+        return {"kind": "playlist", "title": title, "ok": ok, "total": total,
+                "path": None, "lidarr_album_id": None}
+    info = mf.download_single(url, root, quality, False)
+    if not info.get("ok"):
+        raise RuntimeError("Download failed.")
+    return {"kind": "track", "title": info["title"], "artist": info["artist"],
+            "ok": 1, "total": 1, "path": None, "lidarr_album_id": None}
+```
+
+In `server/app.py` `fetch()`, add a URL branch BEFORE the search logic (after the `quality` validation; keep the existing `quality not in mf.QUALITY_CHOICES` 422 check above it). Insert:
+```python
+    if mf.is_url(q):
+        kind = "playlist" if mf.is_playlist_url(q) else "track"
+        syn = mf.Hit(source="youtube", kind=kind, title="", artist="")
+        job = jobs.create_job(hit=syn, message=actions.url_started_message(kind))
+        response = _job_public(job)
+        done_msg = actions.playlist_done_message if kind == "playlist" else actions.url_done_message
+        jobs.run_job(
+            job.id,
+            lambda: actions.perform_url_fetch(q, quality, ROOT),
+            done_message=done_msg,
+            fail_message="Download failed.",
+        )
+        return response
+```
+(The existing `source` validation can stay; it's ignored for URLs. Leave the search path untouched below this branch.)
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `pytest tests/test_api_url.py -v`
+Expected: PASS (4 passed)
+
+- [ ] **Step 5: Full suite**
+
+Run: `pytest -q`
+Expected: all green (58 + callable/export + 4 api-url ≈ 64).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add server/actions.py server/app.py tests/test_api_url.py
+git commit -m "feat(server): route URL/playlist /fetch to download jobs"
+```
+
+---
+
+### Task 5: Live verification
+
+**Files:** none (controller-run).
+
+- [ ] **Step 1: Profiles** — read-only confirm name selection against the real Lidarr:
+```bash
+cd /home/zhering/Documents/musicfetch
+env LIDARR_URL=http://10.2.1.16:8686 LIDARR_API_KEY=49cf02acb4c7436b842df2150056d468 \
+  python3 -c "import server.mf, musicfetch_core as mf; print('meta', mf.get_default_metadata_profile_id(), 'qual', mf.get_quality_profile_id())"
+```
+Expected: `meta 1 qual 1` (Standard / Any). Then with `LIDARR_METADATA_PROFILE=OST` → `meta 3`.
+
+- [ ] **Step 2: Playlist (CLI dry-run)** — confirm expansion + per-track routing without downloading. Pick a small real YT Music playlist URL:
+```bash
+./musicfetch -d "<small-playlist-url>"
+```
+Expected: prints a `[dry-run] yt-dlp …` line per track, each targeting `/media/music/<artist>/youtube`.
+
+- [ ] **Step 3: Playlist (real, small)** — with user approval, run the API against a 3-5 track playlist:
+```bash
+fuser -k 6769/tcp 2>/dev/null; sleep 1
+env MUSICFETCH_API_KEY=testkey MUSICFETCH_ROOT=/tmp \
+  python3 -m uvicorn server.app:app --host 127.0.0.1 --port 6769 --log-level warning &
+sleep 4
+curl -s -X POST 'http://127.0.0.1:6769/fetch?q=<small-playlist-url>' -H 'X-API-Key: testkey'
+# poll /jobs/{id} → expect "Downloaded N/M tracks", files under /tmp/<artist>/youtube/
+fuser -k 6769/tcp 2>/dev/null
+```
+

+
+## Self-Review
+
+**Spec coverage:**
+- Profile-by-name + env overrides + add_artist uses quality profile → Task 1. ✅
+- `is_playlist_url` (watch?v&list → single) → Task 2. ✅
+- `expand_playlist` (ytmusicapi → yt-dlp fallback) → Task 2. ✅
+- `download_playlist` per-track via `act_youtube`, ok/total counting, per-track failures caught → Task 2. ✅
+- `yt_download`/`act_youtube` success bools → Task 2. ✅
+- CLI `handle_url` playlist routing → Task 2. ✅
+- Re-exports + callable batch message → Task 3. ✅
+- API URL routing, playlist batch job, `done` if ok≥1 else `failed`, single-URL job, Siri messages, search path unchanged → Task 4. ✅
+- Live checks (profiles + playlist) → Task 5. ✅
+- Out-of-scope (per-track fan-out, resume/dedup) excluded. ✅
+
+**Placeholder scan:** none — all code/tests complete (the only `<…>` are real user-supplied URLs in the manual Task 5 steps).
+
+**Type consistency:** `download_playlist -> (int,int,str)` consumed as `(ok,total,title)` in CLI + `perform_url_fetch`. `download_single -> {title,artist,ok}` consumed in `perform_url_fetch`. `yt_download`/`act_youtube` now return bool; `act_youtube`'s only other caller (`actions.perform_fetch._download_youtube` in the existing search path) ignores the return value — unaffected. `run_job(done_message)` accepts str or `Callable[[dict],str]`; existing search-path callers pass str (unchanged). `_profile_id_by_name(path, env_var, default_name)` used by both profile getters. New `mf.py` exports (`is_url`, `is_playlist_url`, `download_playlist`, `download_single`) match the names used in `server/app.py` and `server/actions.py`.
