durable-test-collateral

Load the body before the first implementation edit for a bug fix or behavior change, or when the user or governing specification makes reusable tests a deliverable. It keeps the smallest focused test with the delivered project and updates coverage when behavior changes. Do not load for greenfield work unless reusable tests are explicitly required, behavior-preserving refactors, verification-only work, plan/review/explanation/documentation/formatting/generated-output-only work, explicit no-change or no-tool work, or when the user declines tests.

# Durable Test Collateral

Verification is part of the delivered project when it can prevent the same
behavior from breaking again. Use the project's existing framework and
conventions.

## Keep the check with the project

For a bug fix or behavior change, add or update the smallest maintained test in
the repository's normal test layout that exercises the changed behavior. If a
specification makes a reusable suite or test category a deliverable, implement
that suite instead of treating it as private verification.
