# Phase 9 Plan 03: Scan Control UI Summary
|
|
|
|
**Pause/Resume/Cancel scan buttons with modal confirmation dialog wired to backend Wails bindings and scan lifecycle events**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 2 min
|
|
- **Started:** 2026-03-07T02:52:25Z
|
|
- **Completed:** 2026-03-07T02:55:18Z
|
|
- **Tasks:** 1
|
|
- **Files modified:** 3
|
|
|
|
## Accomplishments
|
|
- Scan buttons dynamically swap between Soft Scan/Full Rescan (idle) and Pause/Cancel (active scan)
|
|
- Pause toggles to Resume when scan is paused, with accent-colored status bar message
|
|
- Cancel shows modal dialog with Keep/Discard/Continue options and track count
|
|
- Event handlers for LibraryScanPaused/Resumed/Cancelled update component state
|
|
- Added CancelScan/PauseScan/ResumeScan Wails binding stubs for TypeScript compilation
|
|
- Added `cancelled` field to frontend ScanMetrics interface
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Add scan control state, event handlers, and UI buttons** - `3914369` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `frontend/src/components/config-page/config-page.ts` - Scan control state, event handlers, Pause/Resume/Cancel buttons, cancel dialog, CSS styles
|
|
- `frontend/wailsjs/go/library/Library.d.ts` - CancelScan, PauseScan, ResumeScan, IsScanActive, IsScanPaused type declarations
|
|
- `frontend/wailsjs/go/library/Library.js` - CancelScan, PauseScan, ResumeScan, IsScanActive, IsScanPaused runtime bindings
|
|
|
|
## Decisions Made
|
|
- Discard option shows informational message ("run Full Rescan for clean library") rather than automatically triggering a rescan — safer and less surprising for users
|
|
- Buttons fully swap during scan rather than showing disabled states — clearer UX affordance
|
|
- Cancel dialog uses three options (Keep N tracks / Discard / Continue Scanning) for maximum user control
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 3 - Blocking] Added Wails binding stubs for scan control methods**
|
|
- **Found during:** Task 1 (imports)
|
|
- **Issue:** CancelScan/PauseScan/ResumeScan not in generated Wails binding files — TypeScript would fail to compile
|
|
- **Fix:** Added function declarations and runtime implementations to Library.d.ts and Library.js
|
|
- **Files modified:** frontend/wailsjs/go/library/Library.d.ts, frontend/wailsjs/go/library/Library.js
|
|
- **Verification:** `npx tsc --noEmit` passes
|
|
- **Committed in:** 3914369 (part of task commit)
|
|
|
|
**2. [Rule 3 - Blocking] Included untracked shortcut-capture.ts from Plan 02**
|
|
- **Found during:** Task 1 (commit)
|
|
- **Issue:** `shortcut-capture.ts` was created in Plan 02 but not committed; lefthook pre-commit hook included it in this commit
|
|
- **Fix:** File included in commit — it's a valid component from the keyboard shortcuts plan
|
|
- **Files modified:** frontend/src/components/config-page/shortcut-capture.ts
|
|
- **Verification:** TypeScript compiles cleanly
|
|
- **Committed in:** 3914369 (part of task commit)
|
|
|
|
---
|
|
|
|
**Total deviations:** 2 auto-fixed (2 blocking)
|
|
**Impact on plan:** Both fixes necessary for compilation. No scope creep.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Scan control UI complete, ready for Plan 04 (keyboard shortcut UI) and Plan 05 (integration)
|
|
- All scan control buttons wired to backend Wails bindings
|
|
- Events properly handled for all scan lifecycle states
|
|
|
|
## Self-Check: PASSED
|
|
|
|
- All 3 key files verified on disk (config-page.ts, Library.d.ts, Library.js)
|
|
- Task commit found in git log (3914369)
|
|
- Docs commit: 85573e8
