# RC52 · Testcenter in main menu

Purpose: add one obvious in-app entry point for all QA/test tools instead of relying on hidden query parameters.

## Added

- New top navigation tab: `Testcenter`.
- New screen: `testCenterScreen` with route `#testcenter`.
- Quick links for:
  - Motion Lab / pass runtime test
  - Visual review + correction
  - Motion trace verifier
  - Special prop binding
  - Physio movement blueprint
  - MediaPipe extractor
  - Green motion expansion
- Recommended quick-round checklist.

## Runtime impact

No training runtime logic changed from RC50/RC49 baseline. This is navigation + test tooling only.
