Accept now extends a single-schema chain. Verify walks it; a rewritten payload_hash is a break. Tamper evidence is that detector plus an external chain-head attestation, not WORM.

# Audit Event Retention
|
|
|
|
Audit Core provides the operational custody layer for audit events.
|
|
ITC-CAP join: `operations.audit` at provision maturity D4
|
|
(`data/capability/audit-core-operational.json`). Maturity is not a
|
|
property of this abstract capability.
