Example Verification: Acceptance Evidence

This artifact defines the minimum evidence bundle required to accept a change in the running example. It keeps Chapter 10 grounded in repository evidence rather than retrospective narration.

Required Evidence

Evidence item Why it is required
spec/problem-statement.md and spec/acceptance-criteria.md Proves the accepted result still matches the stated problem and acceptance conditions.
design/commutative-diagram.md and design/artifact-map.md Proves the accepted result follows the canonical artifact path.
verification/review-checks.md and verification/traceability-matrix.md Proves the core claims were reviewed and can be traced across artifacts.
Approved Change Proves the workflow reached the canonical decision outcome artifact.
approval decision record Proves which reviewer, route, and packet produced the decision outcome.
implementation/execution-trace.md Proves effectful execution followed the governed path.
Execution result or return-for-rework note Proves the workflow ended in a named operational outcome.

Acceptance Rule

An accepted change exists only when the evidence bundle points to one Change Identity, one accepted Plan Revision, one Approved Change, and the corresponding approval decision record. If those references disagree, the change is not accepted even if some individual artifacts look complete.

Return-For-Rework Rule

A return-for-rework decision is still a governed outcome and must keep the same evidence shape. The workflow may discard stale implementation outputs, but it may not discard the trace, policy result, or reviewer reason that caused the return.

Relationship To Other Artifacts

This artifact depends on verification/review-checks.md, verification/traceability-matrix.md, implementation/effect-boundary.md, and implementation/execution-trace.md. It closes the specification-to-implementation path used in Chapter 10. It may cite broader audit log evidence when operational review needs it, but those records do not replace the canonical decision outcome or the emitted approval decision record.
