What this rule means

CAIN-42 must always satisfy: AUTHORIZED only by engine+allow. It is one of 501 invariants checked for CAIN-42 Evolution 25 -- Universal Machine Agency Fabric. An invariant is a rule the system may never break, whatever an agent or attacker does; the test suite tries to break it across many scenarios and records the result.

Verify it in your browser

Your browser downloads the bundle's SHA256SUMS manifest and the file(s) behind this page, hashes them with SHA-256 locally (WebCrypto), and compares. A match shows the record you are reading is the published one; it does not by itself prove who published it (see the signed claims registry and the bundle verifier for that).
