SB 53 Frontier Scope

Single-step obligation router for the California SB 53 Transparency in Frontier Artificial Intelligence Act (effective 2026-01-01). Kept as its own composer rather than folded into the CAIA/TRAIGA/AB2013 chains — SB 53 serves a narrow frontier-lab audience, distinct from the general deployer/developer compliance-owner persona of the other state-AI chains.

Asserts a scope/obligation finding only, never that those obligations have been fulfilled. Publishing a safety framework or transparency report is a separate act this chain does not perform or verify. Not legal advice.
