The team's Definition of Done (DoD), both halves of the lifecycle: authoring and auditing. Explains the Scrum Guide's DoD definition ("a formal description of the state of the Increment when it meets the quality measures required for the product"), proposes a starter DoD with the 7-10 lines most teams need (code reviewed, unit tests, docs, AC met, deployed to staging, smoke passed, no a11y regressions, telemetry wired), emits a per-PR checklist a reviewer enforces, and audits work against an existing DoD line by line with repository evidence (review records, diffs, CI runs, coverage reports), tagging every line met, not met, or unverifiable - never passing a line on self-attestation. Use when the team doesn't have a DoD, wants to revise theirs, or is about to mark a story or PR done and nobody has checked the work against the committed checklist.
