# QA RC93 Report

## Scope
Rebuild the exercise library as a clean video-status surface using the current data model.

## Intentional UI changes
Only the exercise library / QA screen is rebuilt. Dashboard, Calendar, Program, Profile, Overview and Exercise Player are not intentionally changed.

## Changed
- Added `assets/js/core/video-registry.js`.
- Added `assets/js/services/video-service.js`.
- Added `assets/js/services/exercise-library-service.js`.
- Added `assets/js/renderers/library-renderer.js`.
- Added `assets/js/actions/library-actions.js`.
- Replaced old `qaScreen` markup with clean `#libraryRoot`.
- `showQa`, `renderLibraryList`, and `showExerciseDetail` now route through the new library action module.
- Added `tests/rc93_library_service_smoke.js`.

## Validation
- JavaScript syntax: OK.
- PHP lint: OK.
- RC91 service smoke test: OK.
- RC92 action smoke test: OK.
- RC93 library/video smoke test: OK.
- ZIP integrity: OK.

## Smoke tests
```bash
node tests/rc91_service_smoke.js
node tests/rc92_action_smoke.js
node tests/rc93_library_service_smoke.js
```

Expected:
```text
RC91 service smoke tests OK
RC92 action smoke tests OK
RC93 library/video service smoke tests OK
```

## QA screenshots
Fallback screenshots generated:
- `qa_screenshots/rc93_library_mobile_390x844.png`
- `qa_screenshots/rc93_library_ipad_820x1180.png`
- `qa_screenshots/rc93_library_desktop_1440x1024.png`

## QA note
Screenshots are static fallback QA fixtures, not live Chromium captures. Chromium/Playwright screenshots remain unreliable in this sandbox. Code syntax, smoke tests and ZIP integrity were verified.

## Manual test focus
- Open exercise library / QA screen.
- Search exercises.
- Filter category.
- Filter video status.
- Open YouTube item.
- Open OTA item.
- Confirm ordinary passes still open and video behavior is unchanged.
