Review the diff against PLAN.md: is every requirement implemented, are the listed edge cases tested, and did anything change that was out of scope? List gaps and scope creep separately. Why it works

PLAN.md catches both under-delivery (missed requirements) and over-delivery
(unrequested changes) in one pass.
Fill in
- Have a
PLAN.md(orSPEC.md) from the planning step to diff against.
