improve-test-coverage is archived (not installed by init): copy it from examples/init-pack/ with its dependency closure, or ask create-workflow to build an equivalent. It runs the shared ValidationLoop, prompted to find and fill high-impact test gaps.

The improve-test-coverage UI shows the high-impact gaps it fills and validates that the new tests pass.
Inputs
Use it when
- A feature landed without enough tests.
- A bug fix needs regression coverage.
- Review/audit found weak boundary coverage.
Use something else when
- Still fixing the bug: use
debugfirst, then this workflow for regression coverage. - Want a broad gap report instead of new tests: use
auditwithfocus: "test coverage".
Resume & retry
Runs the shared validation loop (up to 3 iterations), commits to the working tree, and resumes durably withup --resume.
Transient session/infra errors (SESSION_ERROR, stream disconnects, rate limits, OOMs, timeouts) must never fail a whole run; retry the affected node, let unrelated verified work continue.
