# Phase 6 Summary

**Status:** Complete
**Completed:** 2026-04-26

## Delivered

- Added `internal/teachingassets` for prompt candidates and snapshots.
- Added image model config key `TUTOR_IMAGE_MODEL_KEY`, defaulting to
  `gpt-image-v2`.
- Added workflow contract structs for `OntologyGap` and
  `TeachingAssetPrompt`.
- Added prompt generation from source-backed ontology concepts.
- Added model-id verification guard on every prompt candidate.
- Added HTTP endpoints:
  - `POST /api/v1/teaching-assets/prompts`
  - `GET /api/v1/teaching-assets`
- Added service and HTTP tests.

## Verification

```powershell
gofmt -w cmd internal
go test ./...
openspec validate bootstrap-job-tutor-platform --strict
```

Additional smoke check:

- Material ingestion followed by teaching asset prompt generation returned a
  source-backed prompt with `requires_model_id_verification=true`.

## Deferred

- Real image generation calls.
- Provider SDK integration.
- Binary asset storage.
- Slide/PPT export.
