# Fixture Provenance & Licensing
All fixtures in `tests/fixtures/` must have verified provenance before the Phase 2
licensing hard gate. Only CC0, CC-BY, CC-BY-SA, and public-domain assets are
permitted in the final registry.
All fixtures in `tests/fixtures/` must have verified provenance. Only CC0, CC-BY,
CC-BY-SA, and public-domain assets are permitted in the final registry. Assets
still marked `UNVERIFIED-REVIEW` require human sign-off before the license hard
gate (Phase 2b) can close.

## Provenance Unverified -- Replace in Phase 2
## NEEDS HUMAN LICENSE SIGN-OFF (Category C: UNVERIFIED-REVIEW)
The following `content/` heroes have `UNVERIFIED` license status in `manifest.json`.
Phase 2 will either verify their provenance (CC0/CC-BY source) or replace them with
properly-licensed alternatives:
The following `content/` assets have unverifiable provenance. They were added
during the test coverage expansion (commit `babca4cf`) or QA bug fixes (commit
`d8cf979d`) without recorded source URLs. They are real-world photos, audio, or

1. Verify they are CC0/CC-BY and record the source, OR
2. Replace them with properly-licensed alternatives.
**Do NOT delete these.** Depth tests (face detection, colorization, red-eye
removal, transcription, stress testing) depend on real-world content.

### Recommended Actions for Sign-Off
- **Portraits** (5 files): If AI-generated, confirm the generator and its license terms. If stock photos, identify the source. Consider replacing with CC0 portraits from a known source.
- **Chat screenshots** (2 files): Replace with a project-generated screenshot or a CC0 text image. The chat UI belongs to a third-party app.
- **Red-eye photo**: Source the original from the photographer or replace with a CC0 red-eye portrait.
- **Stress-large photo**: If this is a project contributor's personal photo, have them release it under CC0. Otherwise replace.
- **Watermark landscape**: Source the underlying landscape photo. The watermark overlay was likely added by the project.
- **Speech files** (2 files): Confirm content via playback. If synthetic (ffmpeg-generated), mark CC0. If real speech, identify speaker and get consent or replace.
- **Motorcycle HEIF**: Inspect via HEIF viewer and determine source.
- **OCR-scanned PDF**: Inspect document content and determine source.
