Apply Only What the Update Changes

1. Identify the update's operative changes: A post-update round references a new document or message. Extract exactly which rules it changes.
2. Apply only those changes: Revise only the items the update actually affects.
3. Preserve untouched prior decisions: Every earlier decision the update does not mention stays as it was — same status, same value.
4. Do not over-revise: An update is not a reset. Unrelated prior conclusions must remain stable unless the task explicitly says otherwise.

Example: A bulletin that changes soft-goods billing — revise the soft-goods lines only; an unrelated item already marked "escalate" stays "escalate".

Anti-pattern: Treating an update as a license to re-derive everything, silently changing decisions the update never mentioned.
