pv check-parity — SEMANTIC gate for parity-matrix contracts.
pv validate is the SCHEMA gate — it checks the YAML parses and carries
the fields required by the aprender-contracts schema. A parity-matrix
contract (e.g. contracts/apr-code-parity-v1.yaml, kind: pattern)
additionally encodes a per-row cross_check_command whose output is the
mechanical verification of status. This command runs each row’s
cross-check and compares the hit count against the declared
expected_min_hits / expected_max_hits bounds.
Closes the SEMANTIC half of PMAT-CONTRACTS-PARITY-001.
