One-time migration that splits a repo's existing test suite into a fast unit tier and a slow integration tier — for a repo whose own spec-flow/TESTING.md policy chooses that split, not an assumption the pipeline makes. Classify tests by evidence (container/I-O/timing) and let the compiler + test timings arbitrate, physically separate them (Gradle source set + classpath scoping, or Rust src/ vs tests/ + nextest profiles), wire the CI failures artifact, and open a PR. Run once per repo. See docs/workflow.md ("Test policy"). Never merges.

Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch.
