User description

Summary

  • Bind the services-commands Stryker shard to its direct unit-test files.
  • Keep the selection in the authoritative stryker-scope.json and enforce it with the workflow policy test.

Why

The post-#456 Copilot calibration proved that explicit test selection is required when related-test discovery cannot be trusted. This applies the same bounded, module-specific approach to the three services-commands targets without changing production behavior or mutation thresholds.

Validation

  • pnpm exec vitest run tests/unit/tooling/strykerWorkflowPolicy.test.ts
  • node scripts/stryker-scope.mjs --selector services-commands
  • pnpm run ci:prepush
  • Cloud force mutation run: pending

Scope and non-goals

  • No production-code behavior changes.
  • No threshold, suppression-baseline, or mutation-scope expansion.
  • Full mutation execution remains cloud-only because of the constrained workstation.

Uncertainty

  • The trusted services-commands force-run score and survivor classification are pending the hosted workflow run.

Review coverage

  • CodeRabbit: pending.
  • Other review bots: pending.

Summary by Sourcery

Enforce explicit direct-test coverage for the services-commands mutation shard.

Enhancements:

  • Bind the services-commands mutation shard to its three direct unit-test files and codify the mapping in the workflow policy test.

Tests:

  • Add policy coverage to prevent drift in the services-commands mutation test selection.

CodeAnt-AI Description

Bind services-commands mutation checks to their direct unit tests

What Changed

  • The services-commands mutation shard now runs against its three matching unit-test files
  • Workflow policy tests verify that this test selection remains explicit and correct

Impact

✅ Focused mutation results for services-commands
✅ Fewer unrelated tests in mutation runs
✅ Consistent mutation-test coverage enforcement
