# T01: Added GET /videos/{video_id} and GET /videos/{video_id}/transcript endpoints with creator info, ordered segments, and 5 integration tests

**Added GET /videos/{video_id} and GET /videos/{video_id}/transcript endpoints with creator info, ordered segments, and 5 integration tests**

## What Happened

Added SourceVideoDetail and TranscriptForPlayerResponse schemas to backend/schemas.py. Added two new endpoints to the videos router: GET /{video_id} with selectinload for creator eager-loading, and GET /{video_id}/transcript with video existence check and segment_index ordering. Both return 404 for missing videos. Wrote 5 integration tests covering success, 404, and empty-segments cases.

## Verification

All 5 tests pass: test_get_video_detail_success, test_get_video_detail_404, test_get_transcript_success, test_get_transcript_404, test_get_transcript_empty. Run via pytest against remote PostgreSQL test database through SSH tunnel.
