Answer.

Named jurisdictional law · EU AI Act.

The EU AI Act phases in: prohibited-practice bans applied from early 2025 and GPAI obligations from 2025-08-02. The May 2026 Digital Omnibus provisional agreement moved Annex III high-risk-system obligations to 2027-12-02 (product-embedded high-risk rules follow their own track), so the central high-risk conformity-assessment and post-market-monitoring duties now land 2027-12-02. Planisphere produces reproducible behaviour and drift evidence relevant to the testing and post-market-monitoring obligations; it is not a notified body and does not perform the CE conformity assessment.

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).
