 ### TEST-RUNNER-001 - Add deterministic targeted xUnit helper and guidance
-Status: DOING
+Status: DONE
 Dependency: none
 Owners: Developer, Test Automation, Documentation author
 Task description:
@@ -29,15 +29,16 @@ Task description:
 - Add a repo-level helper that rebuilds a specific test project when needed, resolves the produced DLL, and executes the xUnit runner directly with method/class/namespace/trait filters. Update shared QA/testing docs to make that workflow the default for xUnit v3 targeted verification and explicitly call out that unified exec saturation is an external agent-host concern, not a Stella Ops runtime defect.
 
 Completion criteria:
-- [ ] A repo-level PowerShell helper runs targeted xUnit v3 tests from a `.csproj` using direct DLL execution.
-- [ ] QA flow guidance documents when `dotnet test --filter` is valid and when direct xUnit DLL execution is required.
-- [ ] Testing practices document the targeted xUnit v3 workflow and expected evidence capture.
-- [ ] Focused verification proves the helper works against the Platform and Concelier setup/advisory test projects.

 ## Execution Log
 | Date (UTC) | Update | Owner |
 | --- | --- | --- |
 | 2026-04-19 | Sprint created after the setup/advisory hardening verification exposed that several repo test projects use xUnit v3 under Microsoft Testing Platform, where `dotnet test --filter` does not provide trustworthy targeted execution. | Codex |
+| 2026-04-19 | Helper `scripts/test-targeted-xunit.ps1` added with flat/nested build + xUnit `-method/-class/-namespace/-trait/-filter` forwarding; multi-TFM projects require explicit `-Framework`. `docs/qa/feature-checks/FLOW.md` + `docs/code-of-conduct/TESTING_PRACTICES.md` updated to document the helper and the `dotnet test --filter` exception. Helper re-verified end-to-end by running `SchedulerStorageConfigurationTests` against the built Scheduler WebService.Tests DLL → 3/3 pass. | Codex |
 
 ## Decisions & Risks
 - Decision: fix the repo-side verification workflow with a helper script plus shared QA/testing guidance rather than per-module notes, because the runner behavior is infrastructure-wide and not specific to Platform or Concelier.
