Defined in:

Overview

Implements the append-only iteration cycle. Rather than resetting an approved step back to pending (which would destroy the audit trail), requesting changes clones the track’s current iteration into a fresh one, so every past attempt remains permanently on the ledger.

Always invoked while the approval is locked, so it does not lock again.
