UC-001.md through UC-014.md, each a structured use-case spec with an Overview (including a lifecycle Status field), Preconditions, Main Success Scenario, and Alternative Flows. Sibling AI-UP artifacts sit in docs/: vision.md, requirements.md, entity_model.md, and a use_cases.puml diagram.

Assessment drift: low

Spec-to-code drift

Low. The specs were retrofitted in just over a week (2026-04-24 to 2026-05-02, five commits) and have been untouched since, while the repository kept receiving pushes for roughly two more months. The mitigating signal is that the use cases carry explicit lifecycle Status fields and the final spec commit was Implementing UC-012 to UC-014 — the spec set reads as completed for its scope rather than abandoned mid-flight. Whether the post-May commits are feature work that bypassed the use cases has not been verified.

Defects and rework

Not yet assessed.

Maintenance outcomes

Not yet assessed. Worth watching as a small-team data point: a solo-maintained production-shaped tool (Maven build, compose.yaml, SECURITY.md) that adopted the AI-UP document stack wholesale about three and a half years into the project’s life.
