Evidence records

PayrollAuditLog and PayrollTimeline contain action/timeline labels corresponding to lifecycle operations but are not event contracts. ProcessedIntegrationEvent is an inbound idempotency ledger. OutboxMessage is publication intent, not the business contract itself.

Contract gaps

No Payroll domain events, versioned inbound dispatch, Payroll event dead-letter flow, or consumer for PayrollUnfrozen is confirmed.
