# T01: Created POST /api/v1/ingest endpoint that accepts Whisper transcript JSON uploads, auto-detects creators from folder_name, upserts SourceVideo records, bulk-inserts TranscriptSegments, and persists raw JSON to disk

**Created POST /api/v1/ingest endpoint that accepts Whisper transcript JSON uploads, auto-detects creators from folder_name, upserts SourceVideo records, bulk-inserts TranscriptSegments, and persists raw JSON to disk**

## What Happened

Added python-multipart to requirements.txt. Created TranscriptIngestResponse Pydantic schema in schemas.py with all seven specified fields. Built backend/routers/ingest.py with a POST endpoint that reads and validates uploaded JSON, finds-or-creates a Creator by folder_name using a slugify helper, upserts SourceVideo by (creator_id, filename) with old segment deletion on re-upload, bulk-inserts TranscriptSegments with segment_index, saves raw JSON to transcript_storage_path, and returns a structured response. Mounted the ingest router in main.py under /api/v1. Error handling covers all three failure mode dependencies: 400 for unreadable files, 422 for JSON parse/validation, 500 for DB and filesystem failures.

## Verification

All four slice-level verification checks pass: (1) router.routes outputs ['/ingest'], (2) TranscriptIngestResponse.model_fields.keys() shows all 7 expected fields, (3) grep finds python-multipart in requirements.txt, (4) grep finds ingest in main.py. Additionally confirmed /api/v1/ingest appears in app.routes via full app import.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd backend && python3 -c "from routers.ingest import router; print([r.path for r in router.routes])"` | 0 | ✅ pass | 1000ms |
| 2 | `cd backend && python3 -c "from schemas import TranscriptIngestResponse; print(TranscriptIngestResponse.model_fields.keys())"` | 0 | ✅ pass | 1000ms |
| 3 | `grep -q 'python-multipart' backend/requirements.txt` | 0 | ✅ pass | 100ms |
| 4 | `grep -q 'ingest' backend/main.py` | 0 | ✅ pass | 100ms |
| 5 | `cd backend && python3 -c "from main import app; print([r.path for r in app.routes if 'ingest' in r.path])"` | 0 | ✅ pass | 1000ms |
