Refresh of 18 Oct 2026 under the rule that level A needs the instrument's own text or an official register. Stored in this run: the Assembly Weekly History No. 9 of 30 Nov 2024, the last complete history of the 2023-24 second-year bills compiled under the Chief Clerk (clerk.assembly.ca.gov), the legislature's record of AB 2013, which gives the subject title 'Generative artificial intelligence: training data transparency', the Code title it adds and its approval and chaptering on 28 Sep 2024 as Chapter 817, Statutes of 2024; and again the Senate Judiciary Committee's analysis of AB 412 (hearing of 23 Jun 2026, sjud.senate.ca.gov), which describes Civil Code section 3111 as existing law, with the deadline of 1 Jan 2026 and systems released on or after 1 Jan 2022. Re-read: the Governor's release of 29 Sep 2024 (gov.ca.gov, copy of 17 Oct 2026). The title, date and status now rest on the Assembly's record. The statute's text on leginfo.legislature.ca.gov still refuses automated downloads (HTTP 403), so official_url stays the Governor's release and the summary rests on the committee's description of section 3111. The AB 412 analysis once calls the law the 'California AI Transparency Act', the name of SB 942 (US-CA-02); the record keeps the bill's subject title. date_in_force is the compliance deadline of section 3111; no stored file gives the statute's own effective date.
