Requirement evaluated: The system must maintain an immutable, timestamped, per-action audit log covering every discrete event in the AP lifecycle: invoice receipt, data extraction, coding, each approval action, exception handling, payment initiation, and ERP posting to NetSuite.

The trail must be non-editable after the fact and exportable for audit purposes, satisfying the buyer's stated requirement for an immutable audit trail across the full pre-processing journey.
