Answer.

Named jurisdictional law · EU AI Act.

Post-market monitoring under the AI Act requires providers of high-risk systems to systematically collect and review performance data after deployment, detect emerging risks or degradation, and report serious incidents — an ongoing obligation rather than a one-time conformity check. Recurring, comparable measurement is the natural evidence. Planisphere's re-run cadence produces a drift delta that directly serves post-market monitoring; it surfaces behaviour change for the provider's review, it does not file the regulatory reports or certify conformity.

When EU AI Act 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.

On August 2, 2026, EU AI Act Article 50 and California SB 942 both become enforceable — disclosure and provenance duties on two continents, the same day. Article 50(2) marking carries a transitional: systems already on the market get until December 2, 2026. Audit-grade logging follows: Article 12 binds December 2, 2027 (Annex III) and August 2, 2028 (embedded AI).
