Sprint close
Run these steps in order at the end of every sprint before requesting approval.
Walk every feature delivered in the sprint against its agreed acceptance criteria. Confirm each item is working, not mocked.
Exercise each function end to end, then check layouts at desktop, tablet, and mobile widths.
Log every defect found, resolve it at its source, and retest until the behaviour matches the acceptance criteria.
Quality gates
Compare new screens with previously completed work for shared tokens, spacing, typography, and component patterns.
Re-run prior sprint checks to confirm that earlier features still behave as they did when approved.
Update the record of completed work and remaining requirements before presenting results for review.
