What this rule means

CAIN-42 must always satisfy: CAIN Passport maps to real code or says it is not deployed. It is one of 627 invariants checked for CAIN-42 Evolution 34 -- Proof-Carrying Machine Agency. 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.

Recorded detail

'TESTED library'

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).

Scope: An in-process TESTED library; not hosted. The proof fabric composes E25/E28/E30/E31/E33 but is not wired into the hosted gateway, MCPGate or the clusters.
