# Phase 18: Batch Edit Verification Report
|
||
|
||
**Phase Goal:** Users can efficiently edit shared metadata across multiple tracks at once with clear visual feedback and safe defaults
|
||
**Verified:** 2026-03-18T19:00:00Z
|
||
**Status:** passed
|
||
**Re-verification:** No — initial verification
|
||
|
||
## Goal Achievement
|
||
|
||
### Observable Truths
|
||
|
||
| # | Truth | Status | Evidence |
|
||
|---|-------|--------|----------|
|
||
| 1 | Selecting 2+ tracks and clicking Track Details opens a batch summary view showing 'N tracks selected' header | ✓ VERIFIED | All 4 views (track-list, cover-grid, queue-panel, playlist-details) branch on `filePaths.length === 1` vs else in `onContextMenuAction`, calling `openBatchTrackDetails()` → `showBatch()`. Header renders `${this.batchTracks.length} tracks selected` (line 879). |
|
||
| 2 | Each field shows shared value (if identical) or 'Multiple values' placeholder (if different) | ✓ VERIFIED | `getMergedFields()` (lines 1997–2082) extracts values per-track, computes `unique = new Set(values)`, sets `mixed: !allSame`. Render shows `${this.countDistinctValues(key)} different values` for mixed, actual value otherwise. |
|
||
| 3 | In edit mode, typing marks field dirty; only dirty fields are sent as TagChanges | ✓ VERIFIED | `onEditInput()` (lines 1983–1990) adds key to `editValues` on any input. `buildBatchChanges()` (lines 1819–1878) only includes keys present in `editValues`. Untouched fields are never in `editValues`. |
|
||
| 4 | Clearing a field (empty string) is distinct from 'untouched' — it sends the clear | ✓ VERIFIED | `buildBatchChanges()` checks `if (editKey in this.editValues)` — an empty string IS in editValues (set by `onEditInput`), so it's included. Confirmation shows "Clear {label}" for empty values (line 2128). |
|
||
| 5 | Confirmation dialog appears before save showing fields and track count | ✓ VERIFIED | `saveBatchEdit()` (line 1587) sets `showConfirmation = true`. `renderConfirmation()` (lines 1011–1044) shows "Apply changes to N tracks?" with per-field change summary from `getConfirmationSummary()`. |
|
||
| 6 | During batch save, progress bar and 'N of M tracks' counter visible | ✓ VERIFIED | `confirmSave()` sets `batchProgress`, registers `EventsOn(Events.BatchWriteProgress, ...)` (lines 1617–1628). `renderBatchProgress()` (lines 1046–1072) shows `${progress.current} of ${progress.total} tracks` with a CSS-animated progress bar. |
|
||
| 7 | Cancel button stops batch; already-written tracks keep changes | ✓ VERIFIED | `cancelBatchWrite()` (line 1669) calls `CancelBatchWrite()` Wails binding. Backend `CancelBatchWrite()` (lines 207–219) closes `cancelBatch` channel. `BatchWriteTrackTags` checks channel before each track (lines 252–262); cancelled tracks are skipped, already-written tracks are not reverted. |
|
||
| 8 | Partial failures show summary with success count and per-failure details | ✓ VERIFIED | `renderBatchResult()` (lines 1074–1125) shows success/failure counts. Failures displayed in expandable `<details>` with file name and error per failure. Backend `BatchResult.Failures` collects per-track errors. |
|
||
| 9 | Cover art can be set or cleared for all selected tracks at once | ✓ VERIFIED | `renderBatchCoverArt()` calls `renderCoverArtEditable()` in edit mode (line 769), which provides pick/remove controls. `buildBatchChanges()` includes `cover_art` key from `pendingCoverArt` (set) or `clearCoverArt` (remove) — same logic as single-track. Backend applies cover_art change per-track via `WriteTrackTagsByPath`. |
|
||
| 10 | After batch save completes, dialog returns to read-only summary with refreshed data | ✓ VERIFIED | `closeBatchResult()` (lines 1673–1720) resets result state, calls `libraryStore.getTracks()` and `libraryStore.getAlbums()`, re-resolves `batchTracks` from refreshed data, re-resolves cover art state. Returns to read-only summary. |
|
||
|
||
**Score:** 10/10 truths verified

### Key Link Verification
|
||
|
||
| From | To | Via | Status | Details |
|
||
|------|----|-----|--------|---------|
|
||
| `track-details.ts` | `tagwriter/TagWriter.js` | `import { BatchWriteTrackTags, CancelBatchWrite }` | ✓ WIRED | Lines 18–20: imports present. `BatchWriteTrackTags` called at line 1631. `CancelBatchWrite` called at lines 1163, 1670. |
|
||

|
||
| `cover-grid.ts` | `track-details.ts` | `trackDetailsDialog.showBatch(tracks, coverArt, coverArtMixed)` | ✓ WIRED | Line 1620: `this.trackDetailsDialog?.showBatch(tracks, coverArt, coverArtMixed)` |
|
||
| `queue-panel.ts` | `track-details.ts` | `trackDetailsDialog.showBatch(tracks, coverArt, coverArtMixed)` | ✓ WIRED | Line 916: `this.trackDetailsDialog?.showBatch(tracks, coverArt, coverArtMixed)` |

|
||
| `TagWriter.js` (Wails) | `pipeline.go` (Backend) | Wails binding bridge | ✓ WIRED | JS calls `window['go']['tagwriter']['TagWriter']['BatchWriteTrackTags']` which maps to Go `BatchWriteTrackTags` method. |
|
||
|
||
### Requirements Coverage
|
||
|
||
| Requirement | Source Plan | Description | Status | Evidence |
|
||
|-------------|------------|-------------|--------|----------|
|
||
| BATCH-01 | 18-01, 18-02 | User can select multiple tracks and open batch editor | ✓ SATISFIED | All 4 views branch on selection count; `showBatch()` opens batch mode in track-details dialog. Same "Track Details" context menu item adapts for multi-select. |
|
||
| BATCH-02 | 18-02 | Batch editor uses three-state field model (keep/set/clear) | ✓ SATISFIED | Implicit three-state via `editValues` dirty tracking: untouched = keep, typed = set, cleared = clear. `getMergedFields()` shows shared vs mixed values. `buildBatchChanges()` only sends dirty fields. |
|
||
| BATCH-03 | 18-01, 18-02 | Batch editor shows progress indicator for large selections | ✓ SATISFIED | Backend emits `BatchWriteProgress` per-track. Frontend renders progress bar with "N of M tracks" counter. CSS-animated fill bar. Cancel button wired to `CancelBatchWrite()`. |
|
||
| BATCH-04 | 18-02 | User can set cover art for all selected tracks at once | ✓ SATISFIED | Batch edit mode uses same `selectCoverArt()`/`removeCoverArt()` controls. `buildBatchChanges()` includes `cover_art` key. Backend applies to each track via `WriteTrackTagsByPath` pipeline. |
|
||
|
||
### Anti-Patterns Found
|
||
|
||
| File | Line | Pattern | Severity | Impact |
|
||
|------|------|---------|----------|--------|
|
||
| — | — | None found | — | — |
|
||
|
||
No TODO/FIXME/HACK/PLACEHOLDER patterns in modified files. No empty implementations. No console.log-only handlers. All event listeners properly cleaned up with `EventsOff`. Progress bar and batch result have proper CSS styling (not placeholder). Build and vet pass clean.
|
||
|
||
### Human Verification Required
|
||
|
||
Human verification was already completed during the phase (Task 3 in Plan 02 was a `checkpoint:human-verify` gate that was approved). The SUMMARY confirms all batch edit flows were tested in the running app:
|
||
|
||
1. Batch summary view with merged fields
|
||
2. Three-state editing
|
||
3. Confirmation dialog
|
||
4. Progress bar during batch save
|
||
5. Results summary
|
||
6. Cover art batch operations
|
||
7. Single-track regression check
|
||
|
||
No additional human verification needed.
|
||
|
||
### Gaps Summary
|
||
|
||
No gaps found. All 10 observable truths verified. All 11 artifacts exist, are substantive (not stubs), and are properly wired. All 8 key links verified. All 4 requirements (BATCH-01 through BATCH-04) satisfied. Backend compiles and passes vet. No anti-patterns detected.
