Evaluate declared emission cadence and close AUDIT-WP-0009 (T05)

The contract T05 waited on is published: info-tech-canon
emission-cadence wire schema 0.1, contract digest b08b4d95fc4b0bd3.
A source-owned declaration now travels as emission_cadence on the
sender registration; expected-rate entries raise below_declared_cadence
on /v1/stream-findings from the same counts /v1/reconciliation returns.
heartbeat-or-reconciliation entries are validated and left to T04/T06.

Records the observer evaluation of net-kingdom's local-identity
declaration: structurally clean, not operationally evaluated, one
heartbeat event_class mapping incompatibility.
