Evidence
A normative change must state the problem and the evidence supporting the proposed change.
Compatibility
Meaning-changing work must analyze compatibility, migration and affected consumers.
Decision record
RFC or decision evidence is required when compatibility, governance, hard invariants or ownership change.
Integrity
Canonical hashes and derived artifacts are updated when their selected source bytes change.
CI
Required validation and conformance checks must pass on the reviewed head.
Acceptance
A human maintainer records explicit acceptance before the normative change is merged.
