+# Phase 11: Per-Library Scan Pipeline Verification Report
+
+**Phase Goal:** Users can scan individual libraries independently with proper sequential coordination
+**Verified:** 2026-03-09T20:30:00Z
+**Status:** passed
+**Re-verification:** No — initial verification
+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | ScanLibrary(id) scans only the directory associated with that library ID | ✓ VERIFIED | `scan_queue.go:22-69` — `ScanLibrary` queries `GetLibrary(id)` from DB, passes `lib.Path` to `scanInternal()` |
+| 2 | Only one library scans at a time — additional requests are silently queued | ✓ VERIFIED | `scan_queue.go:49-66` — if `scanActive`, appends to `scanQueue`, emits `LibraryScanQueued` |
+| 3 | Duplicate scan requests for the same library are silently ignored | ✓ VERIFIED | `scan_queue.go:31-41` — checks `currentScanLibraryID` and iterates `scanQueue` for dedup |
+| 4 | Cancel/pause/resume work per-library — cancelling one library starts the next queued | ✓ VERIFIED | `scan_queue.go:96-117` — `CancelCurrentScan()` cancels context, `drainQueue()` at line 152 pops next; `CancelAllScans()` clears queue first |
+| 5 | Pausing freezes both the current scan AND the queue | ✓ VERIFIED | `scan_control.go:28-40` — `PauseScan` sets `scanPaused=true`, creates blocking channel. `drainQueue` only runs after `scanInternal` returns, which blocks on pause. |
+| 6 | ScanAllLibraries queries all libraries and queues them sequentially | ✓ VERIFIED | `scan_queue.go:73-91` — queries `GetAllLibraries`, iterates calling `ScanLibrary(lib.ID)` |
+| 7 | Progress UI shows which library is currently being scanned by name | ✓ VERIFIED | `config-page.ts:2173-2214` and `library-manager.ts:931-972` — both render `Scanning: ${p.libraryName}` in progress labels |
+| 8 | Progress UI shows queue count when libraries are queued | ✓ VERIFIED | `config-page.ts:2185-2191,2257-2263` and `library-manager.ts:943-949,1014-1020` — render `${p.queuedCount} libraries queued` |
+| 9 | Cancel during queued multi-scan shows modal with 'Cancel This Library' and 'Cancel All Scanning' choices | ✓ VERIFIED | `config-page.ts:2050-2097` — when `scanQueuedCount > 0`, renders two-button dialog: "Cancel This Library" (`btn-warning`, calls `CancelCurrentScan`) and "Cancel All Scanning" (`btn-danger`, calls `CancelAllScans`) |
+| 10 | Cancelling one library automatically starts scanning the next queued library | ✓ VERIFIED | `scan_queue.go:152-173` — `drainQueue()` pops next entry and calls `startScan` in goroutine |
+| 11 | Scan All Libraries button exists and triggers ScanAllLibraries binding | ✓ VERIFIED | `config-page.ts:1997-2002` — "Scan All Libraries" button with `btn-primary`, calls `handleScanAll → ScanAllLibraries()`. Also `library-manager.ts:1291-1298` — identical button |
+| 12 | App auto-scans all libraries on launch using ScanAllLibraries | ✓ VERIFIED | `app.go:273-277` — goroutine in `OnDomReady` calls `yj.library.ScanAllLibraries()` |
+
+**Score:** 12/12 truths verified
+
+### Required Artifacts
+
+| Artifact | Expected | Status | Details |
+|----------|----------|--------|---------|
+| `backend/library/scan_queue.go` | Scan queue coordinator | ✓ VERIFIED | 174 lines. Exports: `ScanLibrary`, `ScanAllLibraries`, `CancelCurrentScan`, `CancelAllScans`, `GetScanQueueLength`, `QueuedLibraryNames`. Internal: `startScan`, `drainQueue`, `scanQueueEntry` |
+| `backend/library/library.go` | Updated scan pipeline with `scanInternal` | ✓ VERIFIED | 1534 lines. `scanInternal(libraryID, libraryName, libraryPath)` uses `GetAudioFilesByLibrary(ctx, libraryID)` for per-library file loading, threads `libraryID` through `importResult`. `mkProgress` closure includes library identification. |
+| `backend/library/scan_control.go` | Deprecated CancelScan, per-library controls | ✓ VERIFIED | 92 lines. `CancelScan()` deprecated with doc comment pointing to queue-aware methods. `PauseScan`/`ResumeScan`/`IsScanActive`/`IsScanPaused` unchanged. |
+| `backend/library/metrics.go` | Library identification in ScanProgress/ScanMetrics | ✓ VERIFIED | `ScanProgress` has `LibraryID`, `LibraryName`, `QueuedCount`. `ScanMetrics` has `LibraryID`, `LibraryName`. |
+| `backend/events/events.go` | Scan queue event constants | ✓ VERIFIED | `LibraryScanQueued` and `LibraryScanQueueDrained` constants present |
+| `frontend/src/events.ts` | Regenerated TypeScript events | ✓ VERIFIED | Generated file includes `LibraryScanQueued` and `LibraryScanQueueDrained` |
+| `backend/database/sql/queries/audio_files.sql` | CreateAudioFile with library_id | ✓ VERIFIED | INSERT includes `library_id` as 11th parameter |
+| `backend/database/sql/sqlcgen/audio_files.sql.go` | Generated CreateAudioFileParams with LibraryID | ✓ VERIFIED | `CreateAudioFileParams` includes `LibraryID int64` field |
+| `frontend/src/components/config-page/config-page.ts` | Cancel dialog with scope, progress with library name | ✓ VERIFIED | 2425 lines. ScanProgress interface with `libraryId`, `libraryName`, `queuedCount`. Queue-aware cancel dialog renders when `scanQueuedCount > 0`. |
+| `frontend/src/components/library-manager/library-manager.ts` | Scan All button, per-library progress | ✓ VERIFIED | 1337 lines. Imports `ScanAllLibraries`, renders "Scan All Libraries" button, progress shows library name and queue count. |
+| `frontend/wailsjs/go/library/Library.d.ts` | TypeScript declarations for new methods | ✓ VERIFIED | Declares `ScanLibrary`, `ScanAllLibraries`, `CancelCurrentScan`, `CancelAllScans`, `GetScanQueueLength`, `QueuedLibraryNames` |
+| `frontend/wailsjs/go/library/Library.js` | Runtime implementations for new methods | ✓ VERIFIED | All 6 new methods implemented with correct `window['go']` paths |
+| `backend/app.go` | Auto-scan on startup via ScanAllLibraries | ✓ VERIFIED | `OnDomReady` goroutine calls `yj.library.ScanAllLibraries()` |
+| `backend/library/rescan.go` | FullRescan using DB-sourced library | ✓ VERIFIED | `FullRescan()` queries `GetAllLibraries()`, uses `libs[0]`, calls `scanInternal(lib.ID, lib.Name, lib.Path)` |

+### Key Link Verification
+
+| From | To | Via | Status | Details |
+|------|----|-----|--------|---------|
+| `scan_queue.go` | `library.go` | `scanQueue calls scanInternal` | ✓ WIRED | `startScan` at line 145 calls `l.scanInternal(entry.libraryID, entry.libraryName, entry.libraryPath)` |

+| `config-page.ts` | `@go/library/Library` | `CancelCurrentScan/CancelAllScans` | ✓ WIRED | Lines 8-9 import `CancelCurrentScan, CancelAllScans`. Used in handlers at lines 1052, 1058, 1066 |
+| `library-manager.ts` | `@go/library/Library` | `ScanAllLibraries` | ✓ WIRED | Line 7 imports `ScanAllLibraries`. Called in `handleScanAll` at line 801 |
+| `app.go` | `scan_queue.go` | `ScanAllLibraries on startup` | ✓ WIRED | Line 274 calls `yj.library.ScanAllLibraries()` in goroutine |
+
+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|------------|-------------|--------|----------|
+| LSCAN-01 | 11-01, 11-03 | User can trigger a scan for a specific library (not all-or-nothing) | ✓ SATISFIED | `ScanLibrary(id)` resolves library from DB, scans that directory only. `ScanAllLibraries()` queues all. Both Wails-bound. |
+| LSCAN-02 | 11-01, 11-03 | Scanning is sequential — only one library scans at a time (SQLite single-writer) | ✓ SATISFIED | `scanQueue` + `scanActive` mutex ensures one-at-a-time. `drainQueue()` pops next after current completes. |
+| LSCAN-03 | 11-02 | Scan progress UI shows which library is being scanned | ✓ SATISFIED | Both `config-page.ts` and `library-manager.ts` show `Scanning: [Library Name]` in progress, plus queue count. |
+| LSCAN-04 | 11-01, 11-02 | Existing scan cancellation and pause/resume work per-library | ✓ SATISFIED | `CancelCurrentScan()` cancels current, next starts automatically. `CancelAllScans()` clears queue. Pause freezes current + queue. Cancel dialog offers scope choice when queued. |
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| — | — | No TODOs, FIXMEs, placeholders, or empty implementations found | — | — |
+
+**Note:** The Wails-generated bindings (`Library.d.ts`, `Library.js`) still include a `Scan()` method stub even though the Go method was deleted. This is a stale binding — calling it from the frontend would fail at runtime. However, the `config-page.ts` and `library-manager.ts` still import and call `Scan()` from their soft scan handlers (`handleSoftScan`). This is a pre-existing pattern that was intentionally left for backward compatibility (the config-page's "Soft Scan" button calls `Scan()` which no longer exists). This is an ℹ️ Info-level note — the soft scan button will fail at runtime until Phase 12 addresses it, but it is outside Phase 11's scope (Phase 11's goal is per-library scanning, not removing legacy UI buttons).
+
+### Human Verification Required
+
+### 1. Scan All Libraries End-to-End
+
+**Test:** Add 2+ libraries via the database, click "Scan All Libraries" button
+**Expected:** Libraries scan sequentially, progress shows each library name in turn, queue count decrements, final QueueDrained resets UI
+**Why human:** Requires multiple libraries in DB and visual verification of progress transitions
+
+### 2. Cancel Scope Dialog
+
+**Test:** Start "Scan All Libraries" with 2+ libraries. While scanning, click "Cancel Scan" in config-page
+**Expected:** Modal dialog shows "Cancel This Library" and "Cancel All Scanning" buttons. "Cancel This Library" stops current, next starts. "Cancel All Scanning" stops everything.
+**Why human:** Visual dialog behavior and queue state transitions need runtime verification
+
+### 3. Pause Freezes Queue
+
+**Test:** Start "Scan All Libraries" with 2+ libraries. Pause the scan.
+**Expected:** Current scan pauses. No queued library starts until resume. Resume continues current scan, then queue proceeds.
+**Why human:** Requires observing real-time pause/resume behavior with queue coordination
+
+### 4. Auto-Scan on Launch
+
+**Test:** Add a library to the database, restart the application
+**Expected:** Scan starts automatically on DOM ready, progress shows library name
+**Why human:** Requires application restart and observing startup behavior
