What this rule means
CAIN-42 must always satisfy: a tampered code is refused. It is one of 298 invariants checked for CAIN-42 Evolution 24 -- Governed Agentic Internet 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.
