-# GUI Plan
-
-## Python-first Desktop Architecture
-
-- **Primary GUI framework**: `PySide6` (Qt for Python).
-
-## Core Features to Implement
-
-1. **Dashboard Overview**: List all tracked playlists, their status (Last Sync), and total size.
-2. **Interactive Configuration**: Wizard-style setup for new playlists (URL detection, folder picker).
-3. **Queue Manager**: Visual progress bars for active downloads, showing speed, ETA, and current video title.
-4. **Log Viewer**: Real-time streaming of yt-dlp logs for troubleshooting.
-5. **Settings Panel**: Global settings for binary paths (ffmpeg), max parallel jobs, and Docker detection toggle.
-
-## Phase 1 Roadmap: "The Bridge"
-
-- [ ] **PySide6 Skeleton**: Basic window with `QWebEngine` (if hybrid) or native `QWidget` dashboard.
-- [ ] **Packaging**: `pyinstaller` configuration to bundle both backend and frontend into a single `.exe`.
-
-## Packaging & Distribution (brief)
-
-- Bundle the backend and GUI into one distributable.
-- Windows: use `pyinstaller` or `briefcase` to create an executable/installer. Consider creating an MSI or Inno Setup installer for a polished UX.
-- Linux: provide AppImage, Snap, or distribution-specific packages (deb/rpm) — AppImage is a good starting point for single-file distribution.

+# MP3 Metadata Plan
+
+## Subject Area
+
+- Add MP3 tag writing for downloaded YouTube playlist items.
+- Scope is limited to `.mp3` outputs produced by `audio` mode and the MP3 side of `both` mode.
+- Metadata is sourced from YouTube/yt-dlp and embedded after audio extraction.
+
+## Goal
+
+- Write useful MP3 metadata for downloaded playlist items without affecting video-only downloads.
+- Keep the implementation reliable when optional fields are missing.
+- Preserve successful downloads even when metadata embedding partially fails.
+- Provide a per-playlist setting to enable or disable MP3 metadata embedding.
+
+## Required Metadata
+
+- `title` ← video title
+- `artist` ← uploader, fallback to channel
+- `album` ← album name if present
+- `tracknumber` ← playlist index
+- `date` / `year` ← upload date
+- `comment` ← source URL
+- `genre` ← if available
+- `album_art` ← thumbnail
+
+## Configuration Requirement
+
+- Add a per-playlist setting to turn MP3 metadata embedding on or off.
+- Default should be explicitly defined during implementation; recommended default is `enabled` for new configs.
+- The setting should only affect `.mp3` metadata writing and should not change download selection, extraction, or `.mp4` handling.
+
+## Current Constraints
+
+- The current playlist scan keeps only a minimal item shape: title, video id, and playlist index.
+- The scanner uses flat extraction, which is sufficient for diffing but not for full tag data.
+- MP3 extraction currently transcodes audio but does not write ID3 metadata.
+
+## Implementation Strategy
+
+- Keep playlist diffing fast by retaining the current flat scan for remote playlist structure.
+- Fetch full metadata only for items that are actually going to be downloaded or repaired.
+- Write metadata only after MP3 extraction completes successfully.
+- Treat metadata embedding as a post-processing step that can fail softly without discarding the MP3.
+
+## Work Breakdown
+
+### 1. Extend the metadata model
+
+- Add optional fields to `PlaylistItem` for:
+  - uploader
+  - channel
+  - album
+  - upload_date
+  - genre
+  - thumbnail_url
+  - webpage_url
+- Keep `artist` as a derived value instead of storing a separate field.
+
+### 2. Fetch full per-video metadata
+
+- Introduce a metadata fetch step for each item selected for download.
+- Use yt-dlp per-video extraction to retrieve richer fields than the flat playlist entry provides.
+- Prefer canonical values from the video page payload for upload date, uploader/channel, album, genre, thumbnail, and source URL.
+
+### 3. Carry metadata through the download pipeline
+
+- Ensure the enriched `PlaylistItem` reaches the download job and post-processing stage.
+- Keep this propagation in-memory unless restart-safe metadata persistence becomes necessary later.
+- Avoid changing unrelated sync behavior for video-only items.
+- Carry the per-playlist MP3 metadata enabled/disabled setting into the post-processing step.
+
+### 4. Add an MP3 tag writer
+
+- Add `mutagen` as the ID3 writing dependency.
+- Implement a focused tagging component that maps `PlaylistItem` metadata into ID3 frames.
+- Omit fields when the source value is missing instead of writing placeholders.
+
+### 5. Map fields into ID3 tags
+
+- `title` → video title
+- `artist` → uploader, fallback to channel
+- `album` → album if present
+- `tracknumber` → playlist index
+- `date/year` → parsed upload date
+- `comment` → canonical source URL
+- `genre` → genre if present
+
+### 6. Embed album art
+
+- Download the selected thumbnail for the video after the media download succeeds.
+- Attach thumbnail data as embedded cover art when the image type is supported.
+- Fail soft if thumbnail retrieval or embedding fails, and keep the MP3 intact.
+
+### 7. Integrate into modes
+
+- `audio` mode:
+  - download source media
+  - extract MP3
+  - write MP3 tags only when the setting is enabled
+  - delete temporary/source MP4 if configured
+- `both` mode:
+  - download source media
+  - extract MP3
+  - write MP3 tags only when the setting is enabled
+  - keep MP4 unchanged
+- `video` mode:
+  - no MP3 tagging path
+
+### 8. Add configuration surface
+
+- Add the new per-playlist setting to the playlist config model and default config output.
+- Expose the setting in the playlist configuration UI, not as a global app setting.
+- Keep the naming explicit, for example `write_mp3_metadata` or `embed_mp3_metadata`.
+
+## Error Handling Rules
+
+- If download fails, no tagging runs.
+- If extraction fails, no tagging runs.
+- If metadata embedding is disabled, skip the tagging step entirely.
+- If tagging fails, mark the tag step as failed in logs/events but keep the MP3 file.
+- If thumbnail embedding fails, continue with text metadata only.
+- Missing `album` or `genre` is normal and should not be treated as an error.
+
+## Testing Plan
+
+- Unit test metadata mapping from yt-dlp info to the internal metadata model.
+- Unit test ID3 writing against a temporary MP3 fixture.
+- Unit test fallback behavior:
+  - uploader missing, channel present
+  - album missing
+  - genre missing
+  - thumbnail missing
+- Integration test the audio post-processing path with tagging mocked.
+- Integration test the both-mode MP3 path with tagging mocked.
+
+## Documentation Updates
+
+- Document that MP3 tags are written only for `.mp3` outputs.
+- Document the new per-playlist setting that enables or disables MP3 metadata embedding.
+- Document the field fallback rules, especially artist and album behavior.
+- Document that album art comes from the video thumbnail, not playlist artwork.
+- Document that some YouTube items will not expose album or genre information.
+
+## Dependency Decision
+
+- Recommended library: `mutagen`
+- Reason:
+  - direct ID3 support
+  - reliable field-level control
+  - suitable for embedding cover art
+  - avoids depending on ffmpeg metadata flags for all tag logic
+
+## Delivery Order
+
+- First: add config setting and defaults
+- Second: extend metadata model and add full metadata fetch
+- Third: add MP3 tag writer and field mapping
+- Fourth: add thumbnail embedding
+- Fifth: wire tagging into `audio` and `both`
+- Sixth: add tests and docs

-# YouTube Playlist Sync — Project Conversion Plan
-
-
----
-
-# Project Direction
-
-Convert the project from:
-
-```text
-Single-purpose YouTube playlist downloader
-```
-
-into:
-
-```text
-Persistent YouTube playlist synchronization client
-```
-
-The application becomes state-driven.
-
----
-

-
-- Built-in media playback
-- Advanced naming templates
-- Drag-and-drop manual ordering
-- Private playlist sync
-- Channel subscriptions
-- Metadata editing
-
-Design the architecture so these can be added later.
-
----
-

-
-Recommended approach:
-
-- auto-detect ffmpeg
-- optionally bundle with packaged app
-
----
-
-# Database
-
-## Recommended
-
-- SQLite
-
-Reason:
-
-- Zero setup
-- Local-first architecture
-- Perfect for sync metadata
-- Easy migrations
-- Reliable
-
-SQLite is extremely important for this project.
-
-Do NOT rely only on:
-
-- filenames
-- folders
-- JSON
-
----
-
-# Background Scheduling
-
-## Recommended
-
-- APScheduler
-
-Use for:
-
-- interval syncs
-- delayed jobs
-- retry jobs
-- startup sync
-
----
-
-# Async/Concurrency
-
-## Recommended
-

-- cancellation
-- progress updates
-
----
-
-# Logging
-
-## Recommended
-
-- loguru
-

-
----
-
-# Packaging
-
-## Recommended
-
-### During development
-
-```text
-venv + pip
-```
-
-### Release builds
-
-Choose one:
-
-| Tool        | Notes                           |
-| ----------- | ------------------------------- |
-| Nuitka      | Best performance and protection |
-| PyInstaller | Easier and common               |
-
-Nuitka is probably best long-term.
-
----
-
-# Major Architectural Changes
-
----
-
-# 1. Move to State-Based Sync Architecture
-
-Current downloader logic is likely:
-
-```text
-Playlist URL
-↓
-Download everything
-```
-
-Replace with:
-
-```text
-Remote Playlist State
-↓
-Stored Local State
-↓
-Filesystem State
-↓
-Diff Engine
-↓
-Sync Actions
-```
-
-This is the single most important change.
-
----
-
-# 2. Introduce Playlist Metadata Database
-
-Create persistent tracking.
-
-Suggested tables:
-
-## playlists
-
-```sql
-CREATE TABLE playlists (
-    id TEXT PRIMARY KEY,
-    name TEXT,
-    url TEXT,
-    path TEXT,
-    mode TEXT,
-    auto_sync INTEGER,
-    sync_interval_minutes INTEGER,
-    last_sync TEXT
-);
-```
-
-## playlist\_items
-
-```sql
-CREATE TABLE playlist_items (
-    playlist_id TEXT,
-    video_id TEXT,
-    title TEXT,
-    playlist_index INTEGER,
-    local_filename TEXT,
-    downloaded INTEGER,
-    last_seen TEXT,
-    PRIMARY KEY (playlist_id, video_id)
-);
-```
-
----
-
-# 3. Implement Playlist Scanner Layer
-
-Create dedicated metadata extraction.
-
-Suggested structure:
-
-```text
-core/
- ├── scanner/
- │    └── playlist_scanner.py
-```
-
-Responsibilities:
-
-- fetch playlist entries
-- extract video IDs
-- detect unavailable videos
-- return normalized playlist state
-
-Use:
-
-```python
-extract_info(download=False)
-```
-
-This allows playlist scanning without downloading.
-
----
-
-# 4. Create Diff Engine
-
-The app should compare:
-
-```text
-Remote playlist
-vs
-Database state
-vs
-Filesystem state
-```
-
-Output actions:
-
-```text
-DOWNLOAD
-DELETE
-RENAME
-REORDER
-SKIP
-REPAIR
-```
-
-Suggested file:
-
-```text
-core/sync/diff_engine.py
-```
-
-This becomes the heart of the application.
-
----
-
-# 5. Add Download Queue System
-
-Multi-playlist sync requires a queue.
-
-Suggested states:
-
-```text
-Queued
-Downloading
-Converting
-Completed
-Failed
-Skipped
-Cancelled
-```
-
-Suggested structure:
-
-```text
-core/download/
- ├── queue_manager.py
- ├── downloader.py
- └── workers.py
-```
-
----
-
-# 6. Implement Stable File Naming
-
-Recommended naming:
-
-```text
-0001 - Title.ext
-```
-
-Benefits:
-
-- native filesystem sorting
-- easy reorder support
-- easy repairs
-- user friendly
-
-Use:
-
-```python
-%(playlist_index)04d - %(title)s.%(ext)s
-```
-
-through yt-dlp.
-
----
-
-# 7. Implement Safe Reordering
-
-Playlist ordering changes frequently.
-
-Never rename directly.
-
-Use:
-
-```text
-Temporary rename pass
-↓
-Final rename pass
-```
-
-Example:
-
-```text
-0001.mp3 → temp_a
-0002.mp3 → temp_b
-↓
-temp_a → 0002.mp3
-```
-
-Avoid collisions.
-
----
-
-# 8. Implement Deletion Strategy
-
-Recommended:
-
-Instead of immediate delete:
-
-```text
-playlist/.recycle/
-```
-
-Move removed files there.
-
-Benefits:
-
-- safer
-- recoverable
-- easier debugging
-
-Optional:
-
-- auto-clean after X days
-
----
-
-# 9. Redesign GUI Around Playlists
-
-Current downloader GUIs are usually task-oriented.
-
-You should move to:
-
-```text
-Playlist-oriented UI
-```
-
-Recommended sections:
-
-```text
-Sidebar
- ├── Playlists
- ├── Queue

-# 10. Support Infinite Playlist Entries
-
-Use dynamic UI generation.
-
-Example:
-
-```python
-class PlaylistConfig:
-    url: str
-    path: str
-    mode: str
-    auto_sync: bool
-```
-
-GUI should render from:
-
-```python
-list[PlaylistConfig]
-```
-
-Do NOT hardcode playlist pages.
-
----
-
-# 11. Add Background Sync
-
-Start simple.
-
-## Phase 1
-
-- Timer-based sync
-- Tray icon
-- Run minimized
-
-## Phase 2
-
-- Background daemon/service
-- Headless mode
-- Autostart support
-
----
-
-# 12. Add Progress/Event System
-
-Needed for GUI responsiveness.
-
-Recommended:
-
-```text
-event_bus.py
-```
-
-Events:
-
-```text
-DownloadStarted
-DownloadProgress
-SyncStarted
-SyncFinished
-FileDeleted
-PlaylistUpdated
-```
-
-This decouples GUI from backend.
-
----
-
-# 13. Introduce Config Management
-
-Recommended:
-
-```text
-config.json
-```
-
-Only for:
-
-- app settings
-- UI preferences
-- non-relational settings
-
-Do NOT store sync state in JSON.
-

-
-# Recommended MVP Conversion Order
-
-## Phase 1 — Backend Foundation
-
-Implement:
-
-- SQLite
-- playlist scanner
-- diff engine
-- download wrapper
-- basic sync logic
-
-No GUI redesign yet.
-
----
-
-# Phase 2 — Stable Syncing
-
-Implement:
-
-- deletion handling
-- reorder handling
-- queue system
-- retry system
-- logs
-
----
-
-# Phase 3 — GUI Rewrite
-
-Implement:
-
-- playlist manager UI
-- queue page
-- logs page
-- settings page
-- dynamic playlists
-
----
-
-# Phase 4 — Automation
-
-Implement:
-
-- background sync
-- tray mode
-- startup sync
-- periodic sync

-# Important Recommendations
-
-## Recommendation 1
-
-Treat:
-
-```text
-video_id
-```
-
-as the canonical identity.
-
-Never titles.
-
----
-
-# Recommendation 2
-
-Do NOT rely on yt-dlp archive files alone.
-
-Your own DB should be the source of truth.
-
----
-
-# Recommendation 3
-
-Keep download logic isolated.
-
-yt-dlp should be replaceable internally.
-
----
-
-# Recommendation 4
-
-Do not overcomplicate the GUI early.
-
-Focus on sync correctness first.
-
-Sync reliability matters more than appearance.
-
----
-
-# Recommendation 5
-
-Design everything around interruption recovery.
-
-The app should survive:
-
-- crashes
-- partial downloads
-- force closes
-- network failures
-- playlist changes mid-sync
-
----
-
-# Recommendation 6
-
-Keep the application local-first.
-
-No account system. No cloud backend. No telemetry.
-
-That becomes a strong project identity.
-
----
-
-# Final Recommended Identity
-
-Instead of:
-
-```text
-YouTube Downloader GUI
-```
-
-Position the project as:
-
-```text
-Local-first YouTube playlist synchronization client.
-```
-
-That identity is:
-
-- clearer
-- more unique
-- technically stronger
-- easier to expand later
