Survey binder — one model's whole story

When a surveyor says show me this model, they mean a story with dates: what it is and who approved it, the baseline it was approved at, every attestation since, any incidents, and where each governance control stands. The binder is that story, assembled.

The failure mode is assembly itself. The pieces usually exist — scattered across a committee’s minutes, a data scientist’s notebook, an inbox — and the survey window is when they get hunted, which is exactly when hunting is most expensive. Hence the principle behind survey preparation: maintain the record, and the binder becomes an export. In HAI-OS it is literally one — a single JSON binder per model, with the audit chain’s own integrity verdict and the gap list against the full control set included, generatable today in the demo.
