Handles the housekeeping when a change proposal is done and deployed. It moves the change folder to a timestamped archive and merges spec deltas into your living documentation, processing ADDED, MODIFIED, and REMOVED requirements. The workflow is methodical with an 8-step checklist covering verification, merging each operation type, and validation. Honestly most valuable for the clear merge logic reference, since manually updating requirements across multiple spec files after implementation is exactly the kind of tedious work you'll skip or screw up. Treats archiving as a signal of completion, so it confirms deployment status before moving anything.
