Named jurisdictional law · Colorado AI Act.

After amendment, the Colorado AI Act's effective date was moved to 2027-01-01 (via the SB 26-189 lineage), delaying the original timeline. Because the law has already been revised once, treat the date as subject to further change and verify before relying on it. Planisphere can produce the kind of high-risk-system behaviour and monitoring evidence the Act envisions; it does not give legal advice or guarantee the current effective date.

When Colorado 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.
