M-25-21 expects high-impact AI to be monitored after deployment so that performance degradation or drift is caught, mapping to NIST AI RMF MEASURE 2.4 (monitor functionality and behaviour in production). Useful evidence is a recurring, comparable evaluation against a stable probe set with a recorded delta between runs. Planisphere's single-business-day re-run cadence produces that drift delta as a reproducible artifact; it surfaces behaviour change, it does not decide the remediation.

When NIST AI RMF · MEASURE asks for proof, hand over records — not assurances.

record the duty · seal the receipt · verify offline

Planisphere records each duty event — an output marked, a disclosure shown, a review made — and seals it into a receipt that verifies offline against our published keys. You send hashes, never content. A record is evidence a third party can check; it is not a certification and not a legal determination.
