Phase 6 Research: Teaching Assets

Findings

The product needs lineage before generation. A prompt candidate that carries concept, source evidence, model key, and review state is already useful because it can be reviewed before spending image-generation cost or publishing content.

Recommended Shape

• internal/teachingassets owns asset prompt candidates.
• Use ontology snapshot as the source for concept/evidence lookup.
• Generate prompts deterministically for MVP asset types.
• Store requires_model_id_verification=true so production image generation is blocked until the provider model identifier is verified.

Risks

• Calling image generation before model ID verification would violate PRD.
• Prompt candidates without evidence would weaken provenance.
• Real slide/PPT generation should be a later phase.
