## Files Created

{list of test files created, grouped by tier}

## Real Services Used

{list of services started via docker-compose or testcontainers, or "None (mocks only)"}

## Remaining Gaps

{files or functions still below coverage threshold, with reasons}

## Failures (if any)

{tests that could not be healed after 3 iterations, with failure reason and suggested fix}

## Next Steps

- `/ork:verify {SCOPE}` — grade the implementation + tests
- `/ork:commit` — commit generated test files
- Fix source bugs detected during test generation (if any)

# Before: run coverage with existing tests only
baseline = run_coverage(existing_tests)

# After: run coverage with existing + generated tests
final = run_coverage(existing_tests + generated_tests)

# Delta per file
for file in scope_files:
    delta = final[file] - baseline[file]
    # Report files with biggest delta first

Iteration 1: Fix obvious errors (imports, assertions, setup)
Iteration 2: Fix interaction errors (selectors, timing, state)
Iteration 3: Fix remaining edge cases or mark as known-failing
