/qstack-plan-adherence-review

Audit the implementation against the plan. Treat the plan as the contract, the code and test results as ground truth, and the execution record as supporting evidence that must itself be checked.

This is report-only work. Do not edit the plan, execution record, code, tests, or repository instructions. Do not commit or push. Write an adherence-review.md only when the user explicitly asks for a saved artifact; otherwise report in the final response.
