Archive v1.2 milestone: ROADMAP + REQUIREMENTS + phases to milestones/.
Evolve PROJECT.md with v1.2 validated requirements and key decisions.
Update RETROSPECTIVE.md with v1.2 lessons and cross-milestone trends.
Clean STATE.md for next milestone.
- track-list: branch on selection count, resolve tracks from this.tracks
- cover-grid: branch on selection count, resolve from expandedTracks
- queue-panel: branch on indices count, resolve via libraryStore.getCachedTracks
- playlist-details: branch on selection count, resolve via libraryStore
- Each view determines coverArt/coverArtMixed state and calls showBatch()
- showBatch() API for multi-track entry with merged field values
- Three-state field model: keep/set/clear via dirty tracking in editValues
- Confirmation dialog showing field changes before batch save
- Progress bar with live counter wired to BatchWriteProgress events
- Cancel button calling CancelBatchWrite during batch write
- Results view with success/failure counts and expandable failure details
- Batch cover art: pick, preview, or clear for all selected tracks
- Post-save data refresh returning to updated summary view
- Single-track show() path unchanged (batchMode = false)
- Add BatchFailure and BatchResult types for structured batch outcomes
- Add cancelBatch channel and suppressEvents flag to TagWriter struct
- Add CancelBatchWrite method for mid-batch cancellation from frontend
- Add BatchWriteTrackTags method processing tracks sequentially
- Emit BatchWriteProgress event per-track with current/total/succeeded/failed
- Suppress per-track TrackMetadataChanged; emit single event after batch
- Wails bindings auto-generated for BatchWriteTrackTags and CancelBatchWrite
- tagwriter namespace with BatchResult/BatchFailure in models.ts
After a successful save, re-fetch albums alongside tracks and re-resolve
cover art URLs from the updated album data. Previously the dialog only
refreshed this.track but kept stale this.coverArt URLs pointing to the
old content-hash files, causing the image to revert until reopen.
Three issues fixed:
1. asBytes() helper for []interface{} → []byte conversion — same
float64 deserialization issue as numeric fields. Cover art data
from the frontend arrives as []interface{} of float64, not []byte.
2. DB sync for cover art — was a placeholder no-op. Now saves image
to covers cache dir (content-hash dedup + thumbnail generation),
upserts cover_art row, and updates release_groups.cover_art_id.
Clear sets cover_art_id to NULL on linked release groups.
3. Frontend ReadFile returns base64 string (Go []byte JSON encoding),
not number[]. Decode with atob() before creating Uint8Array for
preview blob URL.
Wails deserializes JSON numbers from JavaScript as float64, not int.
All .(int) type assertions on year, track_number, and disc_number
silently failed. Add asInt() helper, replace all assertions.
After saveEdit() succeeds, re-fetch tracks from library store and update
this.track with the fresh data so the dialog shows updated values instead
of the stale snapshot passed via show().

- REQUIREMENTS.md coverage updated: 31/31 v1.1 requirements complete
- Add ScanHooks callback struct to library package (follows RemovalHooks pattern)
- Move phantom resolution from library to playlist service via hook
- New ResolvePhantomTracksAfterScan reads M3U8 files and resolves paths
against current audio_files using multi-root resolution
- Handles pre-existing phantoms (match by M3U8 position) and new ones
(match by phantom_file_path)
- Delete old resolvePhantomTracks method that required phantom_file_path
- Wire ScanHooks in app.go OnStartup
- Add phantom_file_path column to playlist_tracks (migration 7)
- Store original file_path during RemoveLibrary phantom metadata population
- After each successful scan, UPDATE phantom tracks whose phantom_file_path
now matches an audio_files row, re-linking them and clearing phantom metadata
- Update schema file, sqlc generated code, and database test for new column
- Event delegation handlers were attached in firstUpdated(), but the
virtualizer is conditionally rendered (hidden when tracks empty/loading)
- On first render, tracks are [] so virtualizer doesn't exist, and
firstUpdated() never fires again — delegation was never attached
- Move delegation to a guarded helper called from both firstUpdated()
and updated(), so it attaches as soon as the virtualizer appears
- Fixes click, multi-select, context menu, double-click, and drag in
both track-list and queue-panel components
- GetAllTracksWithFullMetadataByLibrary for tracks filtered by library

- Update all 8 call sites in playlist.go for multi-root resolution
- Update existing test signatures for new []string parameter types
- Fix pre-existing golines formatting in scan_queue.go
- Replace wa-icon shadow DOM with inline SVG in queue-panel (xmark)
and album-dropdown (fav icons) to eliminate per-item shadow roots
- Memoize getBeforeEntries/getAfterEntries in cover-grid to prevent
.slice() creating new array refs that trigger virtualizer relayout
- Remove transition: scale and border-radius from album cards to
avoid per-frame repaints and anti-aliased path clipping
- Add queueMicrotask batching to player-store and favorites-store
notify() to coalesce rapid-fire updates into single renders
display:none discards scrollTop in WebKitGTK, so navigating away
from album/artist/genre grids and back reset scroll to top.
Replace inline style.display toggling with a CSS class that uses
visibility:hidden + height:0 + overflow:hidden. This collapses
the element visually while keeping the DOM alive with its scroll
state intact. contain:strict on hidden views ensures zero layout
cost while collapsed.
Targeted optimizations for the DMABuf-disabled rendering path where
every frame is software-composited:
- Replace infinite CSS scroll-text animation with transition-based
cycle that only repaints during active scroll, not during pauses
- Remove CSS mask-image on scrolling text (mask + animation was the
single most expensive continuous repaint)
- Replace wa-icon in track rows with inline SVG — eliminates 30-50
shadow DOM trees (each with SVG fetch/parse) during scroll
- Remove hover transitions on album cards, artist cards, genre cards,
fav icons, queue remove buttons — each transition was causing
per-frame software repaints
- Use visibility:hidden instead of opacity:0 for queue remove button
(binary switch vs per-frame alpha blend)
- Add decoding=async to now-playing cover art images (prevents
main-thread blocking during image decode on track change)
- Add contain:strict to fixed-height track rows (33px) and queue
items (49px) — browser skips size contribution calculations
Instead of disabling DMABuf for all users (hurting AMD/Intel/X11
performance), detect NVIDIA GPU + Wayland session at startup and
only apply WEBKIT_DISABLE_DMABUF_RENDERER=1 for that combo.
Detection checks /proc/driver/nvidia/version first (fast, no
subprocess), falls back to scanning /proc/modules for nvidia.
GPU policy remains Always for everyone — the DMABuf workaround
only affects buffer sharing between WebKitGTK and the display
server, not GPU-accelerated CSS/layout/paint.
Root causes addressed:
- track-list had no _itemSize hint for flow layout — virtualizer
defaulted to 100px, measured actual ~33px rows, then called
_correctScrollError/scrollTo on every scroll causing visible jumps
- will-change:transform on virtualizer elements caused nested GPU
layers (virtualizer positions children with transforms internally)
adding compositor overhead instead of helping
- content-visibility:auto on album cards conflicted with virtualizer's
own DOM recycling, causing redundant layout recalculation
- track-list visibilityChanged handler wrote to store synchronously
on every event (per-item during scroll) without any throttling
- IIFE closure in renderTrackRow created a new function per row per render
Fixes applied:
- Add _itemSize:{height:33} + fixed height:33px on .track-row (matches
queue-panel pattern that already worked smoothly)
- Add overflow-anchor:none on track-list virtualizer
- Remove will-change:transform from all 6 scroll containers
- Remove content-visibility:auto from album cards
- RAF-throttle visibilityChanged scroll position saves
- Replace IIFE with direct cols.map() in template
contain:strict includes size containment which caused a timing issue
where the flex-based main-panel height wasn't resolved before the
virtualizer measured its container, resulting in track-list rendering
at ~20% height on first load until something triggered a relayout.

Sections start collapsed showing only heading, description, and a
chevron icon. Click to expand and reveal the fields. The open property
allows sections to start expanded if needed.
Progress bar now renders below the library row being scanned, with
a small status label (phase + percent) after the library name. Removed
the separate status-bar progress display.
Add Library now sits in the same row as Scan and Full Rescan, sharing
the same btn-primary style and size. Removed the standalone button
below the library list.
Scan and Full Rescan buttons now sit above the library list for easier
access. Libraries start unchecked — both buttons are disabled until at
least one library is selected.
Go's error interface has no exported fields, so json.Marshal produced
{} for the error message. Converting to string at the addWarning call
site preserves the actual error text in the JSON payload.
