What this rule means

CAIN-42 must always satisfy: knowledge lineage is reconstructable. It is one of 155 invariants checked for CAIN-42 Evolution 21 -- Governed Open-Ended Intelligence 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.
