01
The build
A rolling photo intake inspects the real image bytes, classifies the meal, writes idempotently, and verifies the resulting diary link before a private coach can use it.
02
The useful idea
Multimodal AI is only useful when its evidence survives the handoff. The photo, diary entry, and coach answer need a traceable relationship—not a vague claim that the model saw something.
03
Safety rail
Private retrieval stays server-owned, minimized, owner-gated, and uncached. Duplicate imports count as a successful outcome rather than a reason to create a second record.
