Expense Payroll Dependency Operations

Summary

Payroll participates in two distinct paths: compatibility approval checks whether the claim period is frozen, while lifecycle events update the Payroll-owned approved-expense projection.

Approval guard success does not prove event delivery or projection freshness. Diagnose the claim outcome, Expense outbox status, Payroll processed-event evidence, projection occurrence/status, and calculation eligibility separately.

Frozen runs cannot be recalculated. Later projection changes do not rewrite an already-frozen run through the consumer.

Requires confirmation

Reimbursement-period governance, projection reconciliation ownership, late-event handling, corrections, and frozen-period exception policy require confirmation.
