Both concern the same two scripts, `scripts/vscode/Invoke-MSTestWithCoverage.ps1` and `scripts/vscode/Invoke-MSTest.ps1`, and both must be changed in one place to avoid a merge conflict. + +1. **#891:** a `-SearchRoot`-scoped coverage run always exits 1. + - `Assert-CoberturaLineCoverageThreshold` (`Invoke-MSTestWithCoverage.Threshold.ps1:52`) and the branch assertion compare the document-level Cobertura rate, taken across every instrumented assembly, against the 80% line and 75% branch floors. + - A single-assembly run measures roughly 24% of that denominator, so it fails even when every test passes. + - The assertions are applied unconditionally at `Invoke-MSTestWithCoverage.ps1:386-387`. +2. **#914 sub-item 2:** both scripts carry formatting that the repository PowerShell formatter would rewrite. + +## Environment +- OS/version: Windows 11 Pro 10.0.26200 +- Python version: not applicable (PowerShell 7 toolchain scripts) +- Command/flags used: `./scripts/vscode/Invoke-MSTestWithCoverage.ps1 -SearchRoot QuickFiler.Test -Configuration Debug -CoverageOutput coverage\coverage.cobertura.xml` +- Data source or fixture: `main` at `177b6d78e` + +## Steps to Reproduce +1. Run the command above against an all-green `QuickFiler.Test`. +2. Observe exit code 1 and `Cobertura line coverage 24.3% is below the required 80% threshold.` +3. Run the repository PowerShell formatter (PoshQC format) over `scripts/vscode/`. Observe that it would rewrite the two scripts. + +## Expected Behavior +- A scoped run's exit code reflects the outcome of the tests it executed. Coverage is then either measured over the scoped assemblies only, or the threshold assertion is skipped with an explicit, logged reason. +- The unscoped run (`-SearchRoot .`) keeps enforcing 80% line / 75% branch exactly as it does now. CI (`_mstest-coverage.yml:87-96`, added by PR #897) depends on it and must not be weakened. +- Both scripts are formatter-clean. + +## Acceptance Criteria + +Derived by the preparation orchestrator on 2026-09-28 from Expected Behavior above and the binding operator constraints for run bugs-2026-09-28. Selected approach: automatic skipping of the document-level threshold assertions when the run is scoped, with a logged warning. A run is scoped when the full path of the resolved search root differs from the full path of the repository root (ordinal, case-insensitive, trailing separators ignored); an omitted `-SearchRoot`, `-SearchRoot .`, and `-SearchRoot .\` are all unscoped. No new command-line switch is added, so no caller can opt out of the unscoped gate. + +- [ ] AC1: A scoped run whose test collection succeeds exits without error even when its post-processed Cobertura document is below 80% line and below 75% branch, and it emits exactly one warning stating that the coverage threshold assertions were skipped because the run was scoped to a search root other than the repository root. Demonstrated by a Pester test using an in-memory below-floor Cobertura fixture and mocked collection. +- [ ] AC2: A scoped run whose test collection fails (non-zero collector exit code) still terminates with an error. Demonstrated by a Pester test with mocked collection returning a non-zero exit code. +- [ ] AC3: An unscoped run (omitted `-SearchRoot`, or `-SearchRoot .`) whose post-processed Cobertura document is below the floor still throws the existing threshold message: one Pester test for a below-80% line rate and one for a below-75% branch rate with an at-or-above-80% line rate. The CI coverage workflow file is not modified by this change, and the 80% and 75% literals in the threshold assertions are unchanged. +- [ ] AC4: The scoped-run behavior and the definition of a scoped run are documented in comment-based help in the coverage script. +- [ ] AC5: `scripts/vscode/Invoke-MSTestWithCoverage.ps1` and `scripts/vscode/Invoke-MSTest.ps1` are formatter-clean: a PoshQC format run over `scripts/vscode` after the change leaves both files byte-identical. +- [ ] AC6: PoshQC analyze reports no findings on any changed PowerShell file, the Pester suite passes, and the Pester line-coverage figure over the CI Pester population (the scripts/dependencies and scripts/vscode folders, as measured by the Pester workflow) remains at or above 80% and does not fall below its recorded baseline, with every changed production line covered. (Amended 2026-09-28 by the preparation orchestrator: the scripts/vscode folder alone measured below 80% in earlier committed evidence, so the floor is stated against the population the CI gate actually enforces.) +- [ ] AC7: All committed evidence follows the CLAUDE.md Committed Test Evidence Format section (projections and summaries only, no raw test-result or raw coverage collector document) and contains no absolute host path, developer account name, or host name; the placeholders ``, ``, `` and `` are used instead. + +## Actual Behavior +- Every scoped run fails the threshold gate regardless of test outcome, so plans that scope a run have to fall back to reading the trx. +- The two scripts are not formatter-clean. + +## Logs / Screenshots +- [x] Attached minimal logs or snippet +- Snippet: `Invoke-MSTestWithCoverage.Threshold.ps1:54: Cobertura line coverage 24.3093% is below the required 80% threshold.` (from #891) + +## Impact / Severity +- [ ] Blocker +- [ ] High +- [x] Medium +- [ ] Low + +## Suspected Cause / Notes +The threshold gate was designed for whole-solution runs. `-SearchRoot` narrows the executed tests without narrowing the coverage denominator.

Do not mark evidence-backed work complete without the artifact. + +## Objective + +Make a `-SearchRoot`-scoped run of the coverage runner exit on the outcome of the tests it executed, by skipping the two document-level threshold assertions automatically when the run is scoped, with exactly one warning naming the reason and the search root; keep the unscoped run byte-for-byte on the same two assertion calls; document the behavior in comment-based help; and leave both coverage runner scripts formatter-clean under the repository formatter route. + +## Selected Approach (decided by the preparation orchestrator; not reopened here) + +1. A pure predicate `Test-CoverageRunIsScoped -RepoRoot -ResolvedSearchRoot ` returns true when the full path of the resolved search root differs from the full path of the repository root, compared ordinal case-insensitive with trailing directory separators ignored. An omitted `-SearchRoot`, a lone dot, and a dot followed by a backslash all resolve to the repository root and are unscoped. +2. The entry point calls the predicate once, after post-processing and before the two threshold assertions. When it returns true the entry point writes one warning and skips both assertions; when it returns false the two existing assertion statements run unchanged, in their existing order. +3. No new command-line switch is added. +4. The predicate lives in a new part file so the 500-line ceiling is not approached in the entry point. + +## Design Decisions + +- **D1 — Part file, not the threshold file.** The predicate is declared in a new part file `scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1`. The threshold part file (scripts/vscode/Invoke-MSTestWithCoverage.Threshold.ps1, 127 lines) is not edited: its 80 and 75 literals and both messages must stay unchanged (AC3), and an edit there would widen the diff for no reason. +- **D2 — Dot-sourced from the entry point, not from the helpers chain.** The helpers file (scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1, 472 lines) dot-sources five part files at its lines 2 to 6. Adding a sixth line there would make it a fourth production file in the diff, over the three-production-file per-batch cap in the PowerShell rule file under the .claude rules directory. The entry point already dot-sources the helpers file and the summary part file inside `Invoke-MSTestWithCoverageMain` (lines 289 and 295), so the new part file is dot-sourced there too, after line 295, preceded by its two-line comment (Production Specification edit 1). Production files in the diff are therefore at most three: the entry point, the new part file, and Invoke-MSTest.ps1 (formatting only). +- **D3 — Unscoped path unchanged.** The two statements `Assert-CoberturaLineCoverageThreshold -CoberturaXml $processedXmlContent` and `Assert-CoberturaBranchCoverageThreshold -CoberturaXml $processedXmlContent` (entry point lines 386 and 387 at the base anchor) move into the else arm of the new conditional with their text and order unchanged. Every existing test that mocks or exercises them keeps passing without edits, because every existing entry-point test resolves its search root to the fixture repository root. +- **D4 — Warning literal.** The scoped arm writes one warning whose message begins with the single-line token `Coverage threshold assertions skipped` and continues `: the run is scoped to search root '' rather than the repository root ''.` The message is built from two string literals joined with `+` so no source line exceeds the sibling files' line lengths; the leading token stays on one line. +- **D5 — Help placement.** AC4 is satisfied inside the comment-based help block of `Invoke-MSTestWithCoverageMain` (entry point lines 275 to 278 at the base anchor): a `.DESCRIPTION` paragraph and a `.PARAMETER SearchRoot` paragraph are added. The script-level `param` block at lines 1 to 13 is not given a separate help block, because `Get-Help` on the function is what the new test reads through the abstract syntax tree. +- **D6 — One new test file.** The shared argument-builder test file tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1 measures 499 lines, so it cannot take a single new test. The new tests live in one new file, `tests/scripts/vscode/Invoke-MSTestWithCoverage.Scope.Tests.ps1`, which mirrors the part-file name as the sibling part-file tests do. No existing test file is edited. +- **D7 — Real collection under a mocked executable seam.** The entry-point tests in the new file mock `Invoke-DotnetCoverageExe` (the executable wrapper seam) rather than `Invoke-DotnetCoverageCollection`, so the AC2 case is a genuine non-zero collector exit code (`$global:LASTEXITCODE = 7`) flowing through the real wrapper, exactly as tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1 line 493 already does. The canonical settings read is answered by a filtered `Get-Content` mock, and the derived settings write and removal are answered by `Set-Content` and `Remove-Item` mocks. +- **D8 — No temporary files, no TestDrive.** A search of the tests/scripts/vscode folder for the token `TestDrive` returned 0 matches at the base anchor, so the existing suites do not rely on it and the new file must not introduce it. Every fixture is an in-memory string and every filesystem command the entry point reaches is mocked, following the mock set at tests/scripts/vscode/Invoke-MSTestWithCoverage.AssemblyDiscovery.Tests.ps1 lines 115 to 130. +- **D9 — The formatter route is the MCP PoshQC formatter, and which files it rewrites is run-time derived.** The issue's "would rewrite" claim for the two scripts was measured with a bare `Invoke-Formatter`; the repository formatter route named in the PowerShell rule file under the .claude rules directory is `mcp__drm-copilot__run_poshqc_format`, which rewrote 0 of 46 PowerShell files over these folders on 2026-09-20 (recorded in the issue #911 remediation baseline evidence). AC5 is defined against the MCP route. Phase 0 records the drift set the MCP formatter actually produces on the base tree, which may be empty; no later task assumes either outcome. Invoke-MSTest.ps1 is in the Write Set because the formatter may rewrite it; if it does not, the diff does not touch it and that is recorded, not repaired. +- **D10 — Analyzer reading of AC6 for Invoke-MSTest.ps1.** That script carries two pre-existing `PSAvoidUsingWriteHost` findings at its lines 210 and 211, which its own comment at lines 250 and 251 records as deliberately retained. This plan changes no statement in that file. AC6's "no findings on any changed PowerShell file" is therefore measured as: zero findings for the entry point, the new part file and the new test file (each scoped run returns ok true), and a count equal to the Phase 0 per-file baseline for Invoke-MSTest.ps1. The reading is recorded here so a reviewer can see the choice. The equal-to-baseline reading is a loop gate only. AC6 check-off additionally requires that Invoke-MSTest.ps1 is absent from `git diff --numstat 177b6d78e -- scripts/vscode`, or that the final P2-T2 run (F) returns `ok: true`. +- **D11 — Coverage measurement routes.** The bundled document `mcp__drm-copilot__run_poshqc_test` writes to artifacts/pester/powershell-coverage.xml has been observed (issue #815 evidence, 2026-09-09) to instrument only paths under the .claude and .codex trees and to name no file under the scripts tree. Bash-launched pwsh is refused in this isolated worktree. The coverage tasks therefore take exactly one of three fully specified routes, decided by observation and recorded verbatim: Route A when the bundled document names the changed files; Route C when the direct Pester command (CMD-PESTER-DIRECT) runs and prints a `POPULATION_LINE` line whose covered and missed values are both integers; Route B when neither holds, which writes a measurement work order for the orchestrator and leaves AC6 unchecked. A numeric figure is required for an AC6 check-off; no route reports a placeholder as a figure. +- **D12 — Committed Test Evidence Format.** No raw test-result document and no raw coverage collector document is written under the feature folder: not the bundled JUnit document, not the bundled JaCoCo document, not any Pester JaCoCo output, not any trx. CMD-PESTER-DIRECT writes its JaCoCo output under the repository coverage directory, which .gitignore line 144 ignores. Evidence records derived figures and counts only. +- **D13 — Host-identifier hygiene.** No evidence artifact, no plan text and no issue text may contain an absolute host path, the developer account name or the host name. The MCP tools echo `workspace_root` as an absolute path: transcribe it as ``. Sibling test fixtures use a neutral drive-letter root; when quoting any test name, failure message or console line that carries it, replace the drive-letter root with ``. The final task scans the whole feature folder for two patterns and requires zero matches. +- **D14 — No commit task; intent-to-add only.** The caller owns the commit. No task in this plan runs `git commit`. Each newly created file is registered with `git add -N` immediately after creation so every anchored `git diff 177b6d78e` in Phase 2 can see it; no content is staged. Every worktree-state gate is a negative path-class clause over `git status --porcelain -uall`, never an emptiness clause, because the plan file and the evidence artifacts are uncommitted by construction. +- **D15 — Exit-code conventions per channel.** The MCP tools return `{ok, tool, workspace_root, summary}` plus `stderr_excerpt` on failure and no other field. For a format or analyze artifact, `EXIT_CODE:` is 0 when `ok` is true and 1 when `ok` is false, and `MCP_RESULT_OK_FLAG:` is recorded separately. For a test artifact, `EXIT_CODE:` is derived from the bundled JUnit document at artifacts/pester/pester-junit.xml: 1 when the root `failures` plus `errors` is greater than zero, else 0; the MCP ok flag is recorded separately and a passing final-QC test stage requires it to be true. A direct Pester run, when reachable, sets its own exit through the explicit `exit` statement in CMD-PESTER-DIRECT and is recorded as `DIRECT_PESTER_EXIT:`, never as the artifact's `EXIT_CODE:` row. +- **D16 — Restart rule for the Phase 2 loop.** A step "changes files" when a Write Set PowerShell file's raw-byte hash (`git hash-object --no-filters`) differs across the step, or when the step leaves a porcelain line for a path outside the Write Set under the two script folders that is not a member of the P0-T5 `FORMAT-DRIFT-SET:` (such a path is restored with `git checkout --` and recorded before the restart). A step "fails" when its gate condition is not met. Either restarts the loop at P2-T1 with the iteration number incremented; every artifact carries `iter` in its name so iterations never overwrite one another. + +## Verified Tree Facts (re-derived on the assigned worktree at the base anchor, 2026-09-28) + +Paths in this section are cited as context only and are written without code spans on purpose; the Write Set below is the only place a repository path is backticked. + +- scripts/vscode/Invoke-MSTestWithCoverage.ps1: Read renders 440 numbered lines, the last one empty (439 newline-terminated lines, the count numstat arithmetic uses).

Evidence read: the final-iteration P2-T2 (analyzer conditions), the final-iteration P2-T3 (JUnit conditions and `COVERAGE-ROUTE:`). Acceptance, one of exactly two recorded outcomes: (i) when the final P2-T3 took Route A or C and records `FINAL_POPULATION_LINE_PERCENT:` at or above 80.00 and at or above `BASELINE_POPULATION_LINE_PERCENT:` from P0-T7, both numeric and both taken by the same route, the new part file at or above 90 and `CHANGED-LINES-UNCOVERED: none` for the entry point, for the new part file and, when listed by `git diff --numstat 177b6d78e -- scripts/vscode`, for Invoke-MSTest.ps1, and P2-T2 met every condition, and additionally (per D10) Invoke-MSTest.ps1 is absent from `git diff --numstat 177b6d78e -- scripts/vscode` or the final P2-T2 run (F) returns `ok: true`, the AC6 line changes from `- [ ] AC6:` to `- [x] AC6:` with no other change and the count of `^- \[x\] AC` rises from 5 to 6, and the artifact quotes the figures; (ii) otherwise the AC6 line is left unchanged, the count stays 5, and the artifact records `AC6-STATUS: PENDING` with the reason (`coverage-unmeasurable-in-this-session` on Route B, naming the handoff artifact; `below-floor` with the figures; `below-baseline` with both figures; `baseline-route-mismatch` naming the two routes; or `analyzer-findings-on-changed-file` naming the file and the count), so the plan outcome is reported as remediation-required for AC6 and never as PASS. `EXIT_CODE: 0` in both outcomes; the executor does not edit the AC6 text. +- [ ] [P2-T13] Write the reduced-audit handoff and AC status summary to `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/other/p2-t13-reduced-audit-handoff..md`. Acceptance: the artifact carries the `### Acceptance Criteria Status` block from the `acceptance-criteria-tracking` skill with Source = the issue file, Total 7, Checked off equal to the current Grep count of `^- \[x\] AC` over the issue file (5 or 6 at this point; AC7 is checked by P2-T14), Remaining equal to 7 minus that count, and the remaining item texts; a list of every evidence artifact produced by P0-T1 through P2-T12 by path; the `COVERAGE-ROUTE:` taken and, on Route B, the handoff artifact path and the instruction to the orchestrator to run CMD-PESTER-DIRECT from a session where it runs to completion and prints its `POPULATION_LINE` line (the BASE run at the detached base-anchor checkout and the FINAL run on this worktree, as the handoff artifact's three-part work order states), append `## RESOLUTION` to it, and then check off AC6; the statement that no commit was made and that the Write Set paths are uncommitted in the worktree; `Command: none (handoff record)`; `EXIT_CODE: 0`. +- [ ] [P2-T14] Run the committed-evidence-format and host-identifier scans over `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/` and check off AC7 in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/issue.md`, recording `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t14-evidence-format-and-host-identifier-scan..md`. Steps: (1) Glob the feature folder with the `Glob pattern **/*.xml` and then with the `Glob pattern **/*.trx` (both must return no file: no raw test-result or coverage collector document is under the feature folder); (2) Grep the feature folder, output mode count, with the Rust-regex pattern `(?x) (^|[^A-Za-z]) [A-Za-z] : [\\/]` (a drive-letter path: a letter not preceded by a letter, a colon, then a backslash or slash; the leading class is what keeps a URL scheme from matching) and require 0 matches; (2b) read the `hostname` attribute and the `user` property value from artifacts/pester/pester-junit.xml of the final P2-T3 run, Grep the feature folder case-insensitively for each value with regex metacharacters escaped, require 0 matches, and record `HOST-NAME-SCAN: 0 matches` and `ACCOUNT-NAME-SCAN: 0 matches` without transcribing either value; (3) Grep the feature folder with `(?xi) [\\/] Users [\\/]` (the user-profile directory prefix) and require 0 matches; (4) Grep the evidence subfolder of the feature folder for `workspace_root` and require every matching line to carry `` on the same line (the plan file is excluded from this one check because its command reference names the field without a value); (5) write the artifact with the results of (1) through (4), then change the AC7 line from `- [ ] AC7:` to `- [x] AC7:` with no other change; (6) re-run (2), (2b) and (3) after the artifact and the check-off are written and append `POST-WRITE-RESCAN: 0 matches` only when every count is again 0. Acceptance: (1) returns no file; (2), (2b) and (3) return 0 both times; (4) holds; the Grep count of `^- \[x\] AC` over the issue file equals its P2-T13 value plus 1; `Command: Grep tool and Glob tool, patterns as quoted`; `EXIT_CODE: 0`. Any match is a fix of the offending artifact (placeholder substitution per D13) followed by a re-run of this task from step (1); this task is the last task of the plan so nothing is written after its rescan. + +## Acceptance-Criteria Traceability + +| AC | Implementation | Tests (It numbers per the Test Specification) | Evidence | +|---|---|---|---| +| AC1 | P1-T4 predicate, P1-T5 conditional and warning | 9, 10 | p1-t3-expect-fail, p1-t6-pass-after, p2-t3-test-coverage.iter, p2-t7-ac1-check-off | +| AC2 | unchanged collection throw, exercised through the real wrapper | 11 | p1-t6-pass-after, p2-t3-test-coverage.iter, p2-t8-ac2-check-off | +| AC3 | unchanged else arm (P1-T5), threshold file untouched | 12, 13 | p2-t5-file-size-and-untouched-neighbors, p2-t6-scope-lock, p2-t9-ac3-check-off | +| AC4 | P1-T5 help paragraphs | 14 | p1-t5-entry-point-edit, p2-t10-ac4-check-off | +| AC5 | P1-T7 measured format pass, P2-T1 confirming pass | none (tree observation) | p0-t5-format-baseline, p1-t7-format-measured, p2-t1-format.iter, p2-t11-ac5-check-off | +| AC6 | P2-T2 analyzer, P2-T3 coverage routes, measured over the CI Pester population (scripts/dependencies and scripts/vscode) against the P0-T7 baseline | all 14 (suite green) | p0-t6-analyze-baseline, p0-t7-test-baseline, p2-t2-analyze.iter, p2-t3-test-coverage.iter, p2-t3-coverage-measurement-handoff (Route B), p2-t12-ac6-check-off | +| AC7 | D12 and D13 conventions applied by every artifact | none (folder scan) | p2-t14-evidence-format-and-host-identifier-scan | + +## Planner Self-Review (adversarial pass, revision rounds 3 and 4) + +SELF-REVIEW: RE-DERIVED THIS PASS + +Round-3 re-derivations (every citation the round-3 delta touched, plus siblings): + +- .github/workflows/_pester.yml | line 36 `$ErrorActionPreference = 'Stop'` (the statement CMD-PESTER-DIRECT now opens with, in double quotes because the command is single-quoted for the shell); line 38 `Import-Module Pester -RequiredVersion 5.6.1`; lines 41, 45 and 47 Run.Path, CodeCoverage.Path and CodeCoverage.OutputPath; line 59 the report-level LINE counter XPath; lines 70 to 72 the explicit exits.

P2-T12 outcome (ii) reason `coverage-unmeasurable-in-this-session` covers both the refused and the failed branch because both take Route B.

the P1-T5 two-path numstat clause is consistent with P1-T4's intent-to-add registration (the part file is visible to the anchored numstat before P1-T5 runs) and with P1-T7 running afterwards; the P2-T5 bases 439 and 262 agree with the P0-T4 renderings of 440 and 263 numbered lines with an empty last line; the P2-T6 name-only diff is restricted to the five trees that hold no Write Set docs path, so the promoted record and the feature folder cannot appear in it and its clause can be stated as exactly the four PowerShell files;

Both concern the same two scripts, `scripts/vscode/Invoke-MSTestWithCoverage.ps1` and `scripts/vscode/Invoke-MSTest.ps1`, and both must be changed in one place to avoid a merge conflict. + +1. **#891:** a `-SearchRoot`-scoped coverage run always exits 1. + - `Assert-CoberturaLineCoverageThreshold` (`Invoke-MSTestWithCoverage.Threshold.ps1:52`) and the branch assertion compare the document-level Cobertura rate, taken across every instrumented assembly, against the 80% line and 75% branch floors. + - A single-assembly run measures roughly 24% of that denominator, so it fails even when every test passes. + - The assertions are applied unconditionally at `Invoke-MSTestWithCoverage.ps1:386-387`. +2. **#914 sub-item 2:** both scripts carry formatting that the repository PowerShell formatter would rewrite. + +## Environment +- OS/version: Windows 11 Pro 10.0.26200 +- Python version: not applicable (PowerShell 7 toolchain scripts) +- Command/flags used: `./scripts/vscode/Invoke-MSTestWithCoverage.ps1 -SearchRoot QuickFiler.Test -Configuration Debug -CoverageOutput coverage\coverage.cobertura.xml` +- Data source or fixture: `main` at `177b6d78e` + +## Steps to Reproduce +1. Run the command above against an all-green `QuickFiler.Test`. +2. Observe exit code 1 and `Cobertura line coverage 24.3% is below the required 80% threshold.` +3. Run the repository PowerShell formatter (PoshQC format) over `scripts/vscode/`. Observe that it would rewrite the two scripts. + +## Expected Behavior +- A scoped run's exit code reflects the outcome of the tests it executed.

Then record the coverage baseline by route (D11): Route A when `BUNDLED_NAMES_ENTRY_POINT:` is greater than 0: from the `sourcefile` elements whose name attribute's last path segment is `Invoke-MSTestWithCoverage.ps1` or `Invoke-MSTest.ps1` record LINE covered and missed each, and the population figure as the sum over every `sourcefile` in a package whose name ends with the scripts/dependencies or scripts/vscode segment, as `BASELINE_POPULATION_LINE_PERCENT:` to two decimals; otherwise attempt CMD-PESTER-DIRECT with the value assigned to `$o` changed to coverage/p0-t7-pester-coverage.jacoco.xml (Route C): if it runs and prints a `POPULATION_LINE` line whose covered and missed values are both integers, record `DIRECT_PESTER_EXIT:`, the `PESTER_COUNTS`, `POPULATION_LINE` and `FILE_LINE` lines and `BASELINE_POPULATION_LINE_PERCENT:` = 100 times covered over covered plus missed from `POPULATION_LINE`, to two decimals; if the Bash tool refuses to launch pwsh, record `PWSH-ROUTE: refused` with the refusal text; if it launches but prints no such `POPULATION_LINE` line, record `PWSH-ROUTE: failed` with the error text; in either case replace any absolute path with `` and take Route B: record `BUNDLED-COVERAGE-SCOPE: excludes scripts/dependencies and scripts/vscode` and `BASELINE_POPULATION_LINE_PERCENT: unmeasurable-in-this-session`; the baseline is measured by the P2-T3 handoff at the base anchor.

The unscoped run keeps both assertions unchanged. Records Phase 1 evidence P1-T1 to P1-T7.

Acceptance: `MCP_RESULT_OK_FLAG: true`; `FORMAT-REWROTE:` lists exactly the Write Set files whose HB and HA entries differ (an empty list is a valid observation and is recorded as `FORMAT-REWROTE: none`); every porcelain line after the run names a Write Set path (a line naming any other path is restored with `git checkout -- ` and recorded under `FORMAT-OUT-OF-SCOPE-RESTORED:` before the task completes, and the porcelain is re-taken and recorded); `EXIT_CODE: 0`. ### Phase 2 — Final QC Loop, Check-Off and Hygiene Gates diff --git a/scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 b/scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 new file mode 100644 index 000000000..2b00d1515 --- /dev/null +++ b/scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 @@ -0,0 +1,49 @@ +Set-StrictMode -Version Latest + +# Added for issue #928.

Line 408 is the scoped-arm `Write-Warning`. FINAL_POPULATION_LINE_PERCENT is 94.46 against a baseline of 94.49; the one extra missed line is the whole difference. +- Measured cause, from three diagnostic runs recorded in the P2-T3 artifact: Pester 5.6.1 uses breakpoint-based coverage by default (`CodeCoverage.UseBreakpoints` True). Each test file parses the entry point with `Parser::ParseFile` and dot-sources its own copy. The line breakpoints bind to the copy in the first file that executes `Invoke-MSTestWithCoverageMain`, which in the full run is Invoke-MSTest.RunSettings.Tests.ps1. Hits from a later file's copy are not recorded. With the new test file alone, or ordered first, line 408 is covered (ci=2). Ordered after Invoke-MSTestWithCoverage.AssemblyDiscovery.Tests.ps1, it is not (ci=0). +- A fourth diagnostic run, with `CodeCoverage.UseBreakpoints = $false` (Pester's profiler-based coverage) and the order that reproduces the miss, credited line 408 (ci=2). +- The CI Pester workflow (.github/workflows/_pester.yml lines 44 to 47) does not set `UseBreakpoints`, so CI measures the same way. Its gate is population at least 80 percent, which 94.46 meets, so the CI gate is not affected. +- No fix exists inside the Write Set under the approved specifications. The Test Specification mandates the parse-and-dot-source import, and the Production Specification fixes the conditional block text. The earlier-sorting sibling test files are Out of Scope, and Invoke-MSTest.RunSettings.Tests.ps1 is at 499 lines. D16 prescribes a restart only after a fix, so iteration 2 was not run. P2-T3 and P2-T4 are left unchecked. + +Revision options for the atomic-planner (none evaluated beyond the diagnostics above; the orchestrator decides): + +1. Change the measurement: CMD-PESTER-DIRECT, and optionally the CI workflow as a separate item, sets `$c.CodeCoverage.UseBreakpoints = $false`. Verified on the two-file reproduction only. The baseline must then be re-measured the same way so the route-equality condition in P2-T12 holds. +2. Add one scoped-run case to the first-binding test file. That file is Invoke-MSTest.RunSettings.Tests.ps1, which is at 499 lines and so would need a split, which widens scope. +3. Revise the Production Specification so the scoped and unscoped arms live in the path-loaded Scope part file, and the entry point makes one unconditional call.

Acceptance: the artifact carries the `### Acceptance Criteria Status` block from the `acceptance-criteria-tracking` skill with Source = the issue file, Total 7, Checked off equal to the current Grep count of `^- \[x\] AC` over the issue file (5 or 6 at this point; AC7 is checked by P2-T14), Remaining equal to 7 minus that count, and the remaining item texts; a list of every evidence artifact produced by P0-T1 through P2-T12 by path; the `COVERAGE-ROUTE:` taken and, on Route B, the handoff artifact path and the instruction to the orchestrator to run CMD-PESTER-DIRECT from a session where it runs to completion and prints its `POPULATION_LINE` line (the BASE run at the detached base-anchor checkout and the FINAL run on this worktree, as the handoff artifact's three-part work order states), append `## RESOLUTION` to it, and then check off AC6; the statement that no commit was made and that the Write Set paths are uncommitted in the worktree; `Command: none (handoff record)`; `EXIT_CODE: 0`. +- [x] [P2-T14] Run the committed-evidence-format and host-identifier scans over `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/` and check off AC7 in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/issue.md`, recording `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t14-evidence-format-and-host-identifier-scan..md`. Steps: (1) Glob the feature folder for every file with the xml extension and then for every file with the trx extension, each with the recursive pattern written as double-asterisk, slash, asterisk, dot, extension, rooted at the feature folder (both must return no file: no raw test-result or coverage collector document is under the feature folder); (2) Grep the feature folder, output mode count, with the Rust-regex pattern `(?x) (^|[^A-Za-z]) [A-Za-z] : [\\/]` (a drive-letter path: a letter not preceded by a letter, a colon, then a backslash or slash; the leading class is what keeps a URL scheme from matching) and require 0 matches; (2b) read the `hostname` attribute and the `user` property value from artifacts/pester/pester-junit.xml of the final P2-T3 run, Grep the feature folder case-insensitively for each value with regex metacharacters escaped, require 0 matches, and record `HOST-NAME-SCAN: 0 matches` and `ACCOUNT-NAME-SCAN: 0 matches` without transcribing either value; (3) Grep the feature folder with `(?xi) [\\/] Users [\\/]` (the user-profile directory prefix) and require 0 matches; (4) Grep the evidence subfolder of the feature folder for `workspace_root` and require every matching line to carry `` on the same line (the plan file is excluded from this one check because its command reference names the field without a value); (5) write the artifact with the results of (1) through (4), then change the AC7 line from `- [ ] AC7:` to `- [x] AC7:` with no other change; (6) re-run (2), (2b) and (3) after the artifact and the check-off are written and append `POST-WRITE-RESCAN: 0 matches` only when every count is again 0. Acceptance: (1) returns no file; (2), (2b) and (3) return 0 both times; (4) holds; the Grep count of `^- \[x\] AC` over the issue file equals its P2-T13 value plus 1; `Command: Grep tool and Glob tool, patterns as quoted`; `EXIT_CODE: 0`. Any match is a fix of the offending artifact (placeholder substitution per D13) followed by a re-run of this task from step (1); this task is the last task of the plan so nothing is written after its rescan. ## Acceptance-Criteria Traceability From fc40da640dc57d3428e0fb02279fb7cfe30d46a3 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Tue, 29 Sep 2026 09:52:47 -0400 Subject: [PATCH 07/10] docs(928): add reduced-audit artifacts and remediation inputs for cycle 1 (AC6 changed-line coverage) Co-Authored-By: Claude Opus 5.5 Claude-Session: https://claude.ai/code/session_01KNZiXntshsLY8vqqCHUvHm --- .../code-review.2026-09-29T10-00.md | 60 ++++ .../feature-audit.2026-09-29T10-00.md | 63 ++++ .../policy-audit.2026-09-29T10-00.md | 277 ++++++++++++++++++ .../remediation-inputs.2026-09-29T10-00.md | 56 ++++ 4 files changed, 456 insertions(+) create mode 100644 docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/code-review.2026-09-29T10-00.md create mode 100644 docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/feature-audit.2026-09-29T10-00.md create mode 100644 docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/policy-audit.2026-09-29T10-00.md create mode 100644 docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/remediation-inputs.2026-09-29T10-00.md diff --git a/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/code-review.2026-09-29T10-00.md b/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/code-review.2026-09-29T10-00.md new file mode 100644 index 000000000..f46d004b6 --- /dev/null +++ b/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/code-review.2026-09-29T10-00.md @@ -0,0 +1,60 @@ +# Code Review: coverage-runner-scoped-threshold-and-format (Issue #928) + +- Timestamp label: 2026-09-29T10-00 (assigned without a clock read; see the policy audit header) +- Branch: bug/coverage-runner-scoped-threshold-and-format-928 at a17ca5bcf (caller-supplied) against merge base 177b6d78e +- Files reviewed: scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 (new), scripts/vscode/Invoke-MSTestWithCoverage.ps1 (modified), tests/scripts/vscode/Invoke-MSTestWithCoverage.Scope.Tests.ps1 (new); read in full from the worktree.

No command executed. + +## Executive Summary + +The implementation is small, readable and matches the plan's Production and Test Specifications. The predicate is pure and correctly handles the equivalence cases the AC preamble names (omitted root, `.`, `.\`, trailing separator, letter case) and the two misclassification traps a naive prefix comparison would fall into (a sibling whose name extends the root, and the parent directory). The entry-point edit leaves the unscoped path byte-identical in statement text and order, emits one actionable warning on a scoped run, and does not add any opt-out surface. The test file avoids temporary files and TestDrive, mocks only wrapper seams, and proves the RED-first partition. + +One Blocking finding (CR-1) carries over from the coverage gate: the scoped-arm `Write-Warning` at entry-point line 408 is executed by a passing test but is not credited by the CI-equivalent breakpoint coverage run, because each test file executes its own parsed copy of the entry point and breakpoints bind to the first copy. This is a structural property of where the conditional lives, and the recommended fix is structural: move the gate into the path-loaded part file behind one unconditional call. One Non-blocking finding (CR-2) and eight Informational notes follow. + +Blocking count: 1. + +## Findings Table + +| Severity | File | Location | Finding | Recommendation | Rationale | Evidence | +|---|---|---|---|---|---|---| +| Blocking | scripts/vscode/Invoke-MSTestWithCoverage.ps1 | lines 404 to 414 (conditional block); line 408 | The scoped arm's `Write-Warning` is uncredited by the agreed coverage route: AC6's changed-line clause and baseline clause fail (94.46% vs 94.49%; entry point 89.15% vs 89.68%). The line is executed (It 10 asserts the warning text and passes). Cause: the conditional lives in the entry point, which every suite imports as a separate `ParseFile` copy; Pester 5.6.1 line breakpoints bind to the first copy that runs (`Invoke-MSTest.RunSettings.Tests.ps1`), which never takes the scoped arm. | Relocate the gate into the path-loaded part file: add to `Invoke-MSTestWithCoverage.Scope.ps1` a function (approved verb, singular noun, for example `Assert-CoberturaCoverageThresholdForRun -CoberturaXml -RepoRoot -ResolvedSearchRoot`) whose body is the current conditional verbatim (warning in the scoped arm, the two assertion statements in the same order in the unscoped arm); replace lines 404 to 414 with one call. Add three direct unit cases for the new function (scoped: one warning, no throw; unscoped below line floor: line message; unscoped below branch floor: branch message). First confirm, with the executor's two-file diagnostic shape (AssemblyDiscovery then the new file), that part-file lines are credited from a later-sorting file. Fallback only if that premise fails: maintainer-ratified measurement exception transcribed into issue.md beside AC6. | The rule file makes changed-line coverage regression blocking, and AC6 is explicit. The relocation follows the Coverage Exclusion Policy's own guidance (logic in testable modules, thin wiring in entry points), keeps D3's "unchanged in text and order" property for the two assertion statements, keeps every AC1 to AC5 test valid without edits, and removes the dependence on test-file sort order.

A drive root trims to `C:`-style text on both sides consistently, so root-versus-root still compares equal and root-versus-subdirectory compares unequal (It 8). +- `[string]::Equals(..., OrdinalIgnoreCase)` rather than `-eq` is the right choice: the comparison is explicit and culture-independent. +- A search root of `\..` resolves to the repository root and is treated as unscoped, so the full gate applies; that is the correct outcome for a run that covers the whole tree. +- The `-not` on the equality is the only branch in the file; Pester does not measure branches, and both outcomes are covered by It 1 to 8. + +### Entry-point edit (Invoke-MSTestWithCoverage.ps1) + +- The conditional sits after post-processing and before the first-party report, so a scoped run still prints `Get-CoberturaFirstPartyCoverageReport`, writes the JaCoCo projection and the trx summary, and runs `Assert-JacocoProjectionReconciliation`. That is the intended behavior: only the two document-level floor assertions are skipped. +- The warning names both the resolved search root and the repository root, which makes an accidental scoped run recognisable in the log. `Write-Warning` is the established non-fatal channel in this script (the trx-summary branch at line 441 uses it too). +- The CI workflow invokes `-SearchRoot .` (`_mstest-coverage.yml` line 95) and the VS Code task does the same, so both remain unscoped; `Join-Path '.'` normalises to the repository root through the predicate. The 80 and 75 literals in Threshold.ps1 (lines 52, 54, 122, 124) are unchanged. +- The `.DESCRIPTION` paragraph restates the floors as "80 percent line and 75 percent branch", matching the script; the repository rules state 85 for line coverage. That discrepancy predates this change (policy-audit G-4). + +### Test design (Invoke-MSTestWithCoverage.Scope.Tests.ps1) + +- The guarded part-file import (`if (Test-Path -LiteralPath $script:scopeScript) { . $script:scopeScript }`) is what let the expect-fail run report eight discrete `CommandNotFoundException` failures instead of one block-setup error; the comment above it says so. This is a good pattern for RED-first with a new part file. +- Mocking `Invoke-DotnetCoverageExe` beneath the real `Invoke-DotnetCoverageCollection` means the AC2 case exercises the real exit-code check (`throw "MSTest with coverage failed with exit code 7"`) and the real derived-settings write and finally-block removal, both answered by mocks. `Should -Invoke ConvertTo-KoverageCoberturaXml -Times 0` then proves the run stopped before post-processing. +- The two `Get-Content` parameter-filtered mocks are ordered after the unfiltered default, which is the Pester precedence the sibling suites rely on; the filters key on `$LiteralPath`, matching the production calls at lines 238 and 437. +- `Should -Invoke Write-Warning -Times 1 -Exactly` without a filter is the assertion that proves "exactly one warning" across the whole run, including the trx-summary branch that would otherwise add a second warning; the filtered assertion then proves the content. Both are needed and both are present. +- The fixture drive root `` is the same neutral value the sibling suites use; it is not a host path. + +### Toolchain evidence read + +- Format: hashes identical before and after (P1-T7, P2-T1); liveness proven (P0-T5). +- Analyze: 0 findings on all three changed files (P2-T2 runs C, D, E). +- Test: 334/334 (P2-T3); RED partition 11/3 (P1-T3) then 14/14 (P1-T6). +- Coverage: see CR-1 and the policy audit section 5. diff --git a/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/feature-audit.2026-09-29T10-00.md b/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/feature-audit.2026-09-29T10-00.md new file mode 100644 index 000000000..6f8aa49b7 --- /dev/null +++ b/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/feature-audit.2026-09-29T10-00.md @@ -0,0 +1,63 @@ +# Feature Audit: coverage-runner-scoped-threshold-and-format (Issue #928) + +- Timestamp label: 2026-09-29T10-00 (assigned without a clock read; see the policy audit header) +- Work mode: minor-audit (issue.md line 12, `- Work Mode: minor-audit`) +- AC source: `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/issue.md`, section `## Acceptance Criteria` only (AC1 to AC7). spec.md and user-story.md are absent by design and were not consulted. +- Method: Read, Grep and Glob over the worktree; no command executed (Bash withheld by the caller). + +## Scope and Baseline + +- Branch: bug/coverage-runner-scoped-threshold-and-format-928; head a17ca5bcf (caller-supplied). +- Base anchor: 177b6d78e1b2408e5aedbd794cef3aad6b7fb372, the `git merge-base HEAD origin/main` recorded in evidence/baseline/p0-t3-base-anchor.2026-09-29T08-54.md. +- Code footprint (P2-T6 anchored name-only diff, re-read by this review): scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 (new, +49), scripts/vscode/Invoke-MSTestWithCoverage.ps1 (+29/-2), tests/scripts/vscode/Invoke-MSTestWithCoverage.Scope.Tests.ps1 (new, +232). scripts/vscode/Invoke-MSTest.ps1 unchanged. +- Baselines: format drift set empty on the base tree (P0-T5); analyzer 13 findings in scripts/vscode, 0 in the entry point, 2 in Invoke-MSTest.ps1 (P0-T6); tests 320 passing in 26 suites; Route C population line coverage 94.49% (1613/1707); entry point 113/126 = 89.68%; Invoke-MSTest.ps1 49/56 = 87.50% (P0-T7). +- Post-change: tests 334 passing in 27 suites; population 94.46% (1620/1715); entry point 115/129 = 89.15% with changed line 408 at 0 hits; part file 5/5 = 100.00% (P2-T3). + +## Acceptance Criteria Inventory + +| AC | Text (abridged; full text in issue.md lines 43 to 49) | Checkbox state in issue.md at review start | +|---|---|---| +| AC1 | Scoped run with successful collection exits without error below both floors and emits exactly one warning naming the skip and the scoped search root; Pester test with in-memory below-floor fixture and mocked collection | [x] | +| AC2 | Scoped run with a non-zero collector exit code still terminates with an error; Pester test with mocked collection | [x] | +| AC3 | Unscoped run (omitted or `.`) below the floor still throws the existing messages (one line case, one branch case with line at or above 80); CI coverage workflow not modified; 80 and 75 literals unchanged | [x] | +| AC4 | Scoped-run behavior and the definition of a scoped run documented in comment-based help in the coverage script | [x] | +| AC5 | Both scripts formatter-clean: a PoshQC format run over scripts/vscode after the change leaves both files byte-identical | [x] | +| AC6 | PoshQC analyze reports no findings on any changed PowerShell file; the Pester suite passes; population line coverage over the CI Pester population stays at or above 80% and does not fall below its recorded baseline, with every changed production line covered | [ ] | +| AC7 | Committed evidence follows the Committed Test Evidence Format and contains no absolute host path, account name or host name; placeholders used | [x] | + +Total: 7.

The issue's expectation that the formatter "would rewrite" both scripts was measured with a bare `Invoke-Formatter`, not the repository route (plan D9); against the repository route there was nothing to rewrite, which satisfies the AC as worded. | +| AC6 | PARTIAL (blocking) | Met: analyzer 0 findings on the entry point, the part file and the test file (P2-T2 runs C, D, E `ok: true`), folder count equal to baseline; Pester suite 334/334 (P2-T3, JUnit root re-read: `tests="334" errors="0" failures="0"`); population 94.46% at or above 80%. Not met: 94.46% is below the recorded baseline 94.49% (same route, same command); entry-point changed line 408 (`Write-Warning` in the scoped arm) is uncovered in the full-population breakpoint run. Independent evaluation: the arithmetic reproduces (1620/1715 = 94.461%; +7 covered, +1 missed against the 8 new analyzable lines); the line is executed by It 10, which passes; the crediting gap is order-dependent (three ordered diagnostic runs) and disappears under profiler-based coverage (fourth run), consistent with Pester 5.6.1 line breakpoints binding to the first parsed copy of the entry point (`Invoke-MSTest.RunSettings.Tests.ps1`, which never takes the scoped arm). The AC text and the rule file's changed-line clause are explicit, the plan's loop is recorded as not closed (P2-T4), and a reviewer cannot ratify a measurement exception, so the item is classified blocking. Recommended remediation: relocate the conditional into the path-loaded Scope part file behind one unconditional entry-point call, after confirming with a two-file diagnostic that part-file lines are credited from a later-sorting suite (detail in code-review CR-1 and remediation-inputs R-1).

Six of seven acceptance criteria are verified PASS against the code and the committed evidence. AC6 is PARTIAL: the analyzer and test-pass clauses hold, but the coverage clauses fail by the agreed CI-equivalent measurement route through a crediting defect of breakpoint coverage over per-file parsed copies of the entry point, not through an untested line.

Pester 5.6.1 uses breakpoint-based coverage by default; PowerShell binds a pending line breakpoint to the first compiled copy of the file in which that function executes. In the full run `Invoke-MSTest.RunSettings.Tests.ps1` sorts first (a period sorts before `W`), so entry-point breakpoints bind to its copy, and a line reached only by a later file's copy records no hit. Line 408 is reached only by the new file's scoped cases. The executor's three ordered runs (new file alone: line 408 hit; AssemblyDiscovery then new file: 0 hits; reversed: hit) and a fourth run with profiler-based coverage (hit) are consistent with this mechanism. The part files, by contrast, are dot-sourced by path from inside the entry point, which is the likely reason the new part file reads 5/5 from every test file: PowerShell serves a path dot-source from its per-path compiled-script cache, so all test files share one compiled copy. That premise should be confirmed by one measured two-file run before the remediation below relies on it. + +## 6.

Gaps and Exceptions + +- G-1 (Blocking): AC6 unmet by the agreed measurement route. Two clauses fail: "does not fall below its recorded baseline" (94.46% against 94.49%) and "every changed production line covered" (entry-point line 408). The plan's final QC loop is recorded as not closed (P2-T4 `LOOP-CLOSED: no`; P2-T3 and P2-T4 unchecked). The code behavior the line implements is verified by a passing test (It 10, `Should -Invoke Write-Warning -Times 1 -Exactly` with a parameter filter on the message). Disposition: Blocking until remediated or ratified; see the remediation-inputs artifact. Reviewer's evaluation of the four handoff options: (1) measuring with `UseBreakpoints = $false` is rejected as the primary remedy because the evidence route must match the CI workflow's instrumentation and the baseline would have to be re-measured by the new route; changing CI itself is a separate workflow item requiring a green run. (2) Adding a scoped case to the first-binding sibling file is rejected: that file is out of scope and at 499 lines, and the fix would depend on alphabetical file ordering and recur for the next scoped-only line. (3) Relocating the scoped and unscoped arms into the path-loaded Scope part file behind one unconditional entry-point call is recommended: it follows the Coverage Exclusion Policy's own guidance (thin wiring in the entry point, logic in a testable module), keeps the two assertion statements textually identical and ordered, keeps every AC1 to AC5 test valid, adds a directly unit-testable function, and, if the cache premise holds, credits every line from every test file. Its premise (a path-loaded part file is credited from any test file) must be confirmed with one two-file diagnostic run before adoption. (4) A maintainer-ratified measurement exception is acceptable only as a fallback and only if transcribed into issue.md beside AC6 (a waiver recorded solely in gitignored orchestrator state does not reach the PR). +- G-2 (Informational, pre-existing): the same crediting defect affects any entry-point line reached only by a test file that sorts after `Invoke-MSTest.RunSettings.Tests.ps1`. Recommend promotion to a potential-feature entry: convert the four entry-point suites to dot-source the script by path (the `InvocationName` guard at entry-point line 464 makes that safe) or evaluate profiler-based coverage in `_pester.yml`. +- G-3 (Informational, pre-existing, outside this diff): tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1 lines 41, 42, 104 and 124 embed the developer account name inside literal fixture paths. Recommend a hygiene issue to replace them with a neutral drive-letter fixture root. +- G-4 (Informational): CLAUDE.md states 80% line coverage for PowerShell and the threshold script enforces 80% / 75% for C#, while .claude/rules state 85% / 75%. This is the known unreconciled documentation conflict; this change does not alter any literal, and every figure here clears both floors. +- G-5 (Informational): evidence timestamp labels for P2-T7 to P2-T12 were assigned without a clock read and later renamed to 09-27; the executor disclosed this in P2-T13. Labels are not used for ordering. +- G-6 (Informational): the PR-context artifacts were absent in the worktree and stale in the session root (they describe the `documentationandmemories` branch at 1c80f6e0e). A hand-authored `artifacts/pr_context.summary.txt` was written in the worktree (gitignored) from the executor's verbatim numstat; no appendix could be generated without git access. +- G-7 (Informational): the branch head SHA a17ca5bcf and the commit state (Phase 0 and 1 at ab3b41890 and 313d0b918; Phase 2 evidence committed afterwards, per the caller) were taken from the caller and the handoff record; not re-derived. + +## 9.

In `scripts/vscode/Invoke-MSTestWithCoverage.ps1`, replace lines 404 to 414 with a two-line comment (why the gate lives in the part file: it is path-loaded so every suite credits it, and the entry point stays thin) and one call `Assert-CoberturaCoverageThresholdForRun -CoberturaXml $processedXmlContent -RepoRoot $repoRoot -ResolvedSearchRoot $resolvedSearchRoot`.

The comparison baseline is fixed at the original P0-T7 Route C figure and the post-change figure must come from the identical command, so no Route A or Route B branch exists in this plan. +- Refreshed artifacts keep the original stems with a new timestamp: `p2-t5-file-size-and-untouched-neighbors`, `p2-t6-scope-lock`, `p2-t12-ac6-check-off`, `p2-t13-reduced-audit-handoff`, `p2-t14-evidence-format-and-host-identifier-scan`. Their task identifiers in this plan are P2-T5, P2-T6, P2-T7, P2-T8 and P2-T9; the mapping is stated in each task. +- Phase 0 and Phase 1 artifacts of this plan carry an `r1-` prefix and live under `evidence/remediation-baseline/` (Phase 0) and `evidence/regression-testing/` (Phase 1), so they never overwrite an original artifact. + +## Remediation Decisions + +- **R1 — Diagnostic subject is the Threshold part file, with a control.** The inputs' step 0 names the Scope part file as the coverage subject, but every entry-point suite reaches all five of its current coverage lines through the unscoped arm, so a two-file run over it cannot fail whatever the crediting mechanism does. The premise to prove is that a line of a path-loaded part file reached only by the later-sorting suite is credited. scripts/vscode/Invoke-MSTestWithCoverage.Threshold.ps1 has exactly such lines today: lines 53 and 54 (the line-floor throw) are reached in a two-file run only by It 12 of the new test file, and lines 123 and 124 (the branch-floor throw) only by It 13; the AssemblyDiscovery suite either mocks both assertions (its second Describe) or drives them with a 0.8 fixture (its first Describe; the file contains no sub-floor fixture), so it never reaches those four lines. P0-T7 therefore runs two commands: a control over the AssemblyDiscovery suite alone, which must leave all four lines uncovered, and the ordered two-file run, which must credit all four. The Scope part file is measured in the same two runs and its figure is recorded as the literal check the inputs asked for. Both part files load by the same mechanism (a dot-source by path from a file that is itself compiled once per path), which is the mechanism the fix relies on; the definitive gate remains P2-T3's full-population run. +- **R2 — Production shape.** One new advanced function `Assert-CoberturaCoverageThresholdForRun` in the Scope part file with parameters `-CoberturaXml`, `-RepoRoot`, `-ResolvedSearchRoot` (each `[Parameter(Mandatory = $true)] [string]`), `[CmdletBinding()]`, comment-based help. Body: the predicate call, then in the scoped arm the existing two-literal warning followed by `return`, then the two assertion statements unconditionally. The scoped arm uses `return` rather than an `else` block so the two assertion statements stay at one indentation level and keep their text apart from the parameter variable name (`$CoberturaXml` for `$processedXmlContent`) and their order (line before branch). D3's property is preserved in that form, as the orchestrator directed. +- **R3 — CR-2 guard.** `[ValidateNotNullOrEmpty()]` on both predicate parameters and two fail-fast guards `if (-not [IO.Path]::IsPathRooted(...)) { throw ... }` with the messages `RepoRoot must be an absolute path: ` and `ResolvedSearchRoot must be an absolute path: `. Every `Resolve-Path` mock in the sibling suites returns a rooted fixture path, and the entry point passes `Resolve-Path` output and a `Join-Path` on it, so no existing test reaches either guard. Four negative tests are added: two empty-string cases (controls that pass before and after, because a mandatory string parameter already rejects an empty string; they pin the contract) and two relative-path cases (fail before the guard exists, pass after). +- **R4 — Entry-point wiring.** Lines 404 to 414 (the eleven-line conditional block) are replaced by a two-line comment and one four-line backtick-continued call, mirroring the shape of the existing `Invoke-DotnetCoverageCollection` call at lines 385 to 392. The comment at lines 311 to 312 is reworded to drop the change-budget rationale (CR-3). The `.DESCRIPTION` and `.PARAMETER SearchRoot` help text is unchanged: it describes the run's behavior, not the entry point performing the skip, so It 14 keeps passing. +- **R5 — Tests.** Eight It blocks are added to the existing test file: four negative predicate cases inside the existing `Test-CoverageRunIsScoped` Describe, and one new Describe with four direct cases for the new function. The fourteen existing It blocks are not edited; the P1-T2 gate proves this with an insertion-only diff against HEAD. It 9 to 13 continue to prove AC1 to AC3 through the entry point. +- **R6 — Ceilings.** Scope part file at most 120 newline-terminated lines (expected 104); entry point at most 500 (expected 461); test file at most 500 (expected 304). +- **R7 — Comparison baseline is fixed.** `BASELINE_POPULATION_LINE_PERCENT: 94.49` (covered 1613, missed 94) from the original P0-T7 artifact, measured by CMD-PESTER-DIRECT. P0-T6 of this plan re-runs the identical command on the unmodified tree and must reproduce R-1 (line 408 uncovered); its figure is the pre-remediation starting point, not the comparison baseline. +- **R8 — Stop conditions.** A failed P0-T7 premise is `BLOCKED: part-file-not-credited`; a refused or non-printing direct Pester run at any coverage task is `BLOCKED: direct-pester-unavailable`; neither takes a fallback inside this plan. The orchestrator owns the fallback decision. +- **R9 — No commit, no intent-to-add.** No task runs `git commit` or `git add`. No new repository file is created, so no intent-to-add registration is needed; every anchored diff sees the three edited files as tracked modifications. Every worktree-state gate is a negative path-class clause over `git status --porcelain -uall`, never an emptiness clause and never a count. +- **R10 — Exit-code conventions.** D15 is carried: an MCP format or analyze artifact derives `EXIT_CODE:` from the ok flag; a test artifact derives it from the bundled JUnit root failures plus errors; a direct Pester run's exit is recorded as `DIRECT_PESTER_EXIT:`; an artifact whose expected exit is non-zero carries `ExpectedExitCode:` spelled exactly so, once. +- **R11 — Restart rule.** D16 is carried: a step "changes files" when a Write Set PowerShell file's raw-byte hash differs across the step or the step leaves a porcelain line for an out-of-scope path under the two script folders; a step "fails" when its gate is not met; either restarts at P2-T1 with the iteration number incremented. Iteration numbering continues from the original loop, so the first iteration of this plan is 2. +- **R12 — Host-identifier hygiene.** D13 is carried: `` for the worktree root in transcribed payloads and commands, `` for the neutral drive-letter fixture root in any quoted test text, `` as the substitution token in the two diagnostic commands. This plan file is inside the scanned feature folder, so it carries none of those values. +- **R13 — Promotion candidates excluded.** P-1, P-2 and P-3 of the remediation inputs are not tasks here; P2-T8 names them as owed by the orchestrator. +- **R14 — Sibling suites are unaffected by the relocation.** The two assertion mocks in the AssemblyDiscovery call-site Describe and the line-assertion mock in the ResultsDirectory discard-ordering test already intercept calls made from inside the entry point after its own dot-source of the helpers chain; the relocated call is made one scope deeper from a function defined by the same kind of dot-source, and Pester's mock resolution does not depend on that depth. The RunSettings sub-threshold case reaches the real line assertion through the same path and still throws. + +## Verified Tree Facts (re-derived on the assigned worktree at fc40da640, 2026-09-29) + +Paths in this section are cited as context only and are written without code spans on purpose; the Write Set below is the only place a repository path is backticked. + +- scripts/vscode/Invoke-MSTestWithCoverage.ps1: Read renders 467 numbered lines, the last one empty (466 newline-terminated). `$ErrorActionPreference = 'Stop'` at line 272, unindented, the only occurrence.

Everything else is verbatim, so the post-change figure is measured by the identical command as the 94.49 baseline. The payload is single-quoted so the parent shell does not interpolate `$c`, `$r`, `$o`, `$j`, `$lc`, `$s`, `$n`, `$u` or `$t`; re-quoting must preserve that property.

Acceptance for a passing iteration: `MCP_RESULT_OK_FLAG: true`; HB equals HA for all four files (the AC5 idempotence observation on the edited tree); every porcelain line names a Write Set path (the three edited files are expected as modified), after any listed path outside the Write Set that is a member of the P0-T4 `FORMAT-DRIFT-SET:` has been restored with `git checkout --` and recorded under `FORMAT-PREEXISTING-DRIFT-RESTORED:` (base-tree drift the formatter re-applies on every run; it does not by itself set `RESTART: yes`).

Then repeat the P2-T1 hash command and `git status --porcelain -uall -- scripts tests` and record both. Acceptance for a passing iteration: run (A)'s integer `N_SCRIPTS_FINAL:` is not greater than `N_SCRIPTS_BASELINE:` from P0-T5 (record the delta); runs (B), (C), (D) and (E) are each `ok: true` (zero findings on every changed file and on the test folder); run (F)'s integer equals `N_INVOKE_MSTEST_BASELINE:` from P0-T5 (original D10); the four hashes equal this iteration's P2-T1 HA values and the porcelain over scripts and tests names only Write Set paths (the step changed no file). The artifact's `EXIT_CODE:` row is run (A) with `ExpectedExitCode: 1`; every other run is recorded on its own named line. Any failed condition is a fix inside the Write Set followed by `RESTART: yes` at P2-T1; no suppression attribute or comment is added. +- [ ] [P2-T3] Test step in coverage mode, iteration N, recorded in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t3-test-coverage.iter..md` (this task re-runs the original plan's P2-T3 with the superseded literals stated in the Relationship section). Run CMD-TEST with `scan_folders = ["scripts/dependencies", "scripts/vscode", "tests/scripts/dependencies", "tests/scripts/vscode"]`; read artifacts/pester/pester-junit.xml and record the root `tests`, `failures` and `errors`, the `testsuite` count, and the `tests` and `failures` values of the testsuite whose leaf name is `Invoke-MSTestWithCoverage.Scope.Tests.ps1`; Grep the document for `.jacoco.xml (N substituted) and the Set-Location substitution; record `COVERAGE-ROUTE: C`, `DIRECT_PESTER_EXIT:`, the `PESTER_COUNTS`, `POPULATION_LINE` and `FILE_LINE` lines, `FINAL_POPULATION_LINE_PERCENT:` = 100 times covered over covered plus missed from `POPULATION_LINE` to two decimals, and each production file's percentage as 100 times (total minus uncovered) over total from its `FILE_LINE` line.

Afterwards run `git status --porcelain -uall` and, if a line reading ?? coverage.xml is present, remove that one file with git clean -f and the pathspec coverage.xml, and record it. Acceptance for a passing iteration: root `failures` 0 and `errors` 0; root `tests` equals `TESTS_START:` from P0-T6 plus 8, which is 342; the `testsuite` count is 27; the Scope testsuite reports `tests` 22 and `failures` 0; `.md` and check off the two open tasks of the original plan. Acceptance: the artifact tables every iteration from 1 upward with, per iteration, the artifact name and `RESTART:` value of each of P2-T1, P2-T2 and P2-T3 that ran in that iteration, and `not run (restart at P2-T1)` for a step that did not run because an earlier step of the same iteration recorded `RESTART: yes` (iteration 1 is taken from evidence/qa-gates/p2-t1-format.iter1.2026-09-29T09-16.md, p2-t2-analyze.iter1.2026-09-29T09-18.md and p2-t3-test-coverage.iter1.2026-09-29T09-23.md, whose third step recorded `RESTART: yes` as prescribed and not executed); the final iteration is the only one whose three steps all record `RESTART: no` and all meet their passing conditions, and its three artifacts carry the same `iter` token; the artifact records `LOOP-CLOSED: yes`; then, in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/plan.2026-09-28T19-45.md`, the line beginning `- [ ] [P2-T3]` becomes `- [x] [P2-T3]` and the line beginning `- [ ] [P2-T4]` becomes `- [x] [P2-T4]` with no other character of either line changed and no other edit to that file, so that its Grep count of `^- \[ \] \[P` falls from 2 to 0 and its counts of `^- \[x\] \[P2-T3\]` and `^- \[x\] \[P2-T4\]` are each 1 (both counts recorded); `Command: none (reconciliation of the step artifacts) plus two Edit-tool check-offs`; `EXIT_CODE: 0`.

Acceptance: every porcelain line names a Write Set path, a path under the feature folder, a path under the agent-memory tree beneath the .claude directory, or a path under the docs/features/potential/promoted folder, and no porcelain line names a path under scripts/ or tests/ other than the four Write Set PowerShell files; every path the name-only diff lists is one of the four Write Set PowerShell files, and the two Scope files and the entry point are each listed; no porcelain line reads ?? coverage.xml; the artifact records both listings verbatim (the porcelain listing is non-empty by construction and its count is deliberately not asserted); `EXIT_CODE: 0`. +- [ ] [P2-T7] Decide AC6 in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/issue.md` and record `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/regression-testing/p2-t12-ac6-check-off..md` (refreshing the original P2-T12 stem). Evidence read: the final-iteration P2-T2 and P2-T3 artifacts of this plan, the P2-T4 closure, and the original P0-T7 baseline artifact. Acceptance, one of exactly two recorded outcomes: (i) when P2-T4 records `LOOP-CLOSED: yes`, the final P2-T3 records `COVERAGE-ROUTE: C`, `FINAL_POPULATION_LINE_PERCENT:` at or above 80.00 and at or above 94.49 (the original P0-T7 `BASELINE_POPULATION_LINE_PERCENT:`, same route, identical command), the Scope part file at or above 90, and `CHANGED-LINES-UNCOVERED: none` for the entry point, for the Scope part file and, when listed by `git diff --numstat 177b6d78e -- scripts/vscode`, for Invoke-MSTest.ps1, the final P2-T2 met every condition, and additionally (original D10) Invoke-MSTest.ps1 is absent from that numstat or the final P2-T2 run (F) returns `ok: true`, then the AC6 line changes from `- [ ] AC6:` to `- [x] AC6:` with no other character of the line changed, the Grep count of `^- \[x\] AC` over the issue file rises from 6 to 7, and the artifact quotes every figure with its source artifact path; (ii) otherwise the AC6 line is left unchanged, the count stays 6, and the artifact records `AC6-STATUS: PENDING` with the reason (`loop-not-closed`; `below-floor` with the figure; `below-baseline` with both figures; `changed-line-uncovered` with the file and line numbers; `part-file-below-90` with the figure; `analyzer-findings-on-changed-file` naming the file and the count; or `direct-pester-unavailable`), so the plan outcome is reported as remediation-required for AC6 and never as PASS. `EXIT_CODE: 0` in both outcomes; the executor does not edit the AC6 text. +- [ ] [P2-T8] Write the refreshed reduced-audit handoff and AC status summary to `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/other/p2-t13-reduced-audit-handoff..md` (refreshing the original P2-T13 stem).

Steps: (1) Glob the feature folder for every file with the xml extension and then for every file with the trx extension, each with the recursive pattern written as double-asterisk, slash, asterisk, dot, extension, rooted at the feature folder (both must return no file); (2) Grep the feature folder, output mode count, with the Rust-regex pattern `(?x) (^|[^A-Za-z]) [A-Za-z] : [\\/]` (a drive-letter path; the leading class keeps a URL scheme from matching) and require 0 matches; (2b) read the `hostname` attribute and the `user` property value from artifacts/pester/pester-junit.xml of the final P2-T3 run, Grep the feature folder case-insensitively for each value with regex metacharacters escaped, require 0 matches, and record `HOST-NAME-SCAN: 0 matches` and `ACCOUNT-NAME-SCAN: 0 matches` without transcribing either value; (3) Grep the feature folder with `(?xi) [\\/] Users [\\/]` and require 0 matches; (4) Grep the evidence subfolder of the feature folder for `workspace_root` and require every matching line to carry `` on the same line; (5) write the artifact with the results of (1) through (4); (6) re-run (2), (2b) and (3) after the artifact is written and append `POST-WRITE-RESCAN: 0 matches` only when every count is again 0. AC7 is already checked and is not re-checked here: the Grep count of `^- \[x\] AC` over the issue file is recorded and must equal its P2-T8 value.

the RunSettings sub-threshold case still reaches the real line assertion; the numstat arithmetic 14 plus 4 plus 6 equals 24 added against 2 deleted, and 466 minus 5 equals 461; the Scope part-file line count of 104 was counted line by line from the Production Specification; the P0-T4 control numstat is 30 and 3 because the committed diff is 29 and 2 and the control perturbs one unchanged line; the P0-T7 counts 5 and 19 come from the AssemblyDiscovery It count and the executor's recorded two-file run; the empty-string controls (It 15 and 16) pass before the attribute exists because a mandatory string parameter already rejects an empty string, which is why they are labelled controls and excluded from the fail-before set; no line of this plan carries a drive-letter path, a user-profile prefix, the account name or the host name, so the P2-T9 scan over the feature folder is satisfiable with this file present. + +PLANNER-INTERNAL-REVIEW: PASS +CITATION-TO-TREE: PASS +AC-TRACEABILITY: PASS +SCOPE-BOUNDARY: PASS +CITATION: scripts/vscode/Invoke-MSTestWithCoverage.ps1 | lines 272, 275-292, 303, 309, 311-313, 323-324, 385-392, 403-415, 441, 464-466 (Read renders 467 lines) +CITATION: scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 | lines 1, 3-6, 8, 31-38, 41-49 (Read renders 50 lines) +CITATION: scripts/vscode/Invoke-MSTestWithCoverage.Threshold.ps1 | lines 52-54 and 122-124 +CITATION: tests/scripts/vscode/Invoke-MSTestWithCoverage.Scope.Tests.ps1 | lines 25-27, 30, 36-37, 76-131, 133-161, 165-216, 220-232 (Read renders 233 lines) +CITATION: tests/scripts/vscode/Invoke-MSTestWithCoverage.AssemblyDiscovery.Tests.ps1 | lines 13-18, 26-56, 108-175;

Round 1 returned REVISIONS REQUIRED with six deltas, all applied in revision round 2. The historical note that follows describes the line as the planner originally wrote it: the PREFLIGHT line above was the planner's placeholder for the mechanical record only: no defect is known in this plan, and clearance is outstanding because validation-only preflight through atomic-executor and the MCP plan validator have not yet run (the planner has neither tool). The executor's preflight return replaces it. From 408ac211f4f24376f525af2a477a4d2da50525ec Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Tue, 29 Sep 2026 11:00:43 -0400 Subject: [PATCH 09/10] fix(928): move the scoped threshold gate into the path-loaded Scope part file so every changed line is credited Adds Assert-CoberturaCoverageThresholdForRun to Invoke-MSTestWithCoverage.Scope.ps1; the entry point makes one unconditional call. Test-CoverageRunIsScoped now rejects empty and relative paths. Adds 8 Pester tests (22 in the suite). Full-population Pester line coverage 94.53 percent against the 94.49 baseline, with no uncovered changed line. AC6 checked off. Records remediation cycle 1 evidence.

Run `git diff --numstat 177b6d78e -- scripts/vscode tests/scripts/vscode`.

Acceptance: every porcelain line names a Write Set path, a path under the feature folder, a path under the agent-memory tree beneath the .claude directory, or a path under the docs/features/potential/promoted folder, and no porcelain line names a path under scripts/ or tests/ other than the four Write Set PowerShell files; every path the name-only diff lists is one of the four Write Set PowerShell files, and the two Scope files and the entry point are each listed; no porcelain line reads ?? coverage.xml; the artifact records both listings verbatim (the porcelain listing is non-empty by construction and its count is deliberately not asserted); `EXIT_CODE: 0`. -- [ ] [P2-T7] Decide AC6 in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/issue.md` and record `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/regression-testing/p2-t12-ac6-check-off..md` (refreshing the original P2-T12 stem). Evidence read: the final-iteration P2-T2 and P2-T3 artifacts of this plan, the P2-T4 closure, and the original P0-T7 baseline artifact. Acceptance, one of exactly two recorded outcomes: (i) when P2-T4 records `LOOP-CLOSED: yes`, the final P2-T3 records `COVERAGE-ROUTE: C`, `FINAL_POPULATION_LINE_PERCENT:` at or above 80.00 and at or above 94.49 (the original P0-T7 `BASELINE_POPULATION_LINE_PERCENT:`, same route, identical command), the Scope part file at or above 90, and `CHANGED-LINES-UNCOVERED: none` for the entry point, for the Scope part file and, when listed by `git diff --numstat 177b6d78e -- scripts/vscode`, for Invoke-MSTest.ps1, the final P2-T2 met every condition, and additionally (original D10) Invoke-MSTest.ps1 is absent from that numstat or the final P2-T2 run (F) returns `ok: true`, then the AC6 line changes from `- [ ] AC6:` to `- [x] AC6:` with no other character of the line changed, the Grep count of `^- \[x\] AC` over the issue file rises from 6 to 7, and the artifact quotes every figure with its source artifact path; (ii) otherwise the AC6 line is left unchanged, the count stays 6, and the artifact records `AC6-STATUS: PENDING` with the reason (`loop-not-closed`; `below-floor` with the figure; `below-baseline` with both figures; `changed-line-uncovered` with the file and line numbers; `part-file-below-90` with the figure; `analyzer-findings-on-changed-file` naming the file and the count; or `direct-pester-unavailable`), so the plan outcome is reported as remediation-required for AC6 and never as PASS. `EXIT_CODE: 0` in both outcomes; the executor does not edit the AC6 text. -- [ ] [P2-T8] Write the refreshed reduced-audit handoff and AC status summary to `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/other/p2-t13-reduced-audit-handoff..md` (refreshing the original P2-T13 stem). Acceptance: the artifact carries the `### Acceptance Criteria Status` block from the `acceptance-criteria-tracking` skill with Source = the issue file, Total 7, Checked off equal to the current Grep count of `^- \[x\] AC` over the issue file (7 after outcome (i) of P2-T7, 6 otherwise), Remaining equal to 7 minus that count, and the remaining item texts (none, or the AC6 text); a list by path of every evidence artifact produced by P0-T1 through P2-T7 of this plan; `COVERAGE-ROUTE: C` with the final iteration number; the statement that the original plan's P2-T3 and P2-T4 were checked off by P2-T4 of this plan (or were not, with the reason); the statement that no commit was made and that the three edited PowerShell files, the issue file, the original plan file, this plan file and the new evidence artifacts are uncommitted in the worktree; the three promotion candidates P-1, P-2 and P-3 named as excluded from this cycle and owed by the orchestrator through the potential-feature lifecycle; `Command: none (handoff record)`; `EXIT_CODE: 0`. -- [ ] [P2-T9] Run the committed-evidence-format and host-identifier scans over `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/` (refreshing the original P2-T14 stem), recording `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t14-evidence-format-and-host-identifier-scan..md`. Steps: (1) Glob the feature folder for every file with the xml extension and then for every file with the trx extension, each with the recursive pattern written as double-asterisk, slash, asterisk, dot, extension, rooted at the feature folder (both must return no file); (2) Grep the feature folder, output mode count, with the Rust-regex pattern `(?x) (^|[^A-Za-z]) [A-Za-z] : [\\/]` (a drive-letter path; the leading class keeps a URL scheme from matching) and require 0 matches; (2b) read the `hostname` attribute and the `user` property value from artifacts/pester/pester-junit.xml of the final P2-T3 run, Grep the feature folder case-insensitively for each value with regex metacharacters escaped, require 0 matches, and record `HOST-NAME-SCAN: 0 matches` and `ACCOUNT-NAME-SCAN: 0 matches` without transcribing either value; (3) Grep the feature folder with `(?xi) [\\/] Users [\\/]` and require 0 matches; (4) Grep the evidence subfolder of the feature folder for `workspace_root` and require every matching line to carry `` on the same line; (5) write the artifact with the results of (1) through (4); (6) re-run (2), (2b) and (3) after the artifact is written and append `POST-WRITE-RESCAN: 0 matches` only when every count is again 0. AC7 is already checked and is not re-checked here: the Grep count of `^- \[x\] AC` over the issue file is recorded and must equal its P2-T8 value. Acceptance: (1) returns no file; (2), (2b) and (3) return 0 both times; (4) holds; the recorded AC count equals the P2-T8 value; `Command: Grep tool and Glob tool, patterns as quoted`; `EXIT_CODE: 0`. Any match is a fix of the offending artifact (placeholder substitution per R12) followed by a re-run of this task from step (1); this task is the last task of the plan so nothing is written after its rescan. +- [x] [P2-T1] Format step of the final toolchain loop, iteration N (N starts at 2), recorded in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t1-format.iter..md`. Run `git hash-object --no-filters -- scripts/vscode/Invoke-MSTestWithCoverage.ps1 scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 scripts/vscode/Invoke-MSTest.ps1 tests/scripts/vscode/Invoke-MSTestWithCoverage.Scope.Tests.ps1` (record HB), `git status --porcelain -uall -- scripts/vscode tests/scripts/vscode` (record), CMD-FORMAT, the hash command again (record HA), the porcelain again (record). Acceptance for a passing iteration: `MCP_RESULT_OK_FLAG: true`; HB equals HA for all four files (the AC5 idempotence observation on the edited tree); every porcelain line names a Write Set path (the three edited files are expected as modified), after any listed path outside the Write Set that is a member of the P0-T4 `FORMAT-DRIFT-SET:` has been restored with `git checkout --` and recorded under `FORMAT-PREEXISTING-DRIFT-RESTORED:` (base-tree drift the formatter re-applies on every run; it does not by itself set `RESTART: yes`). If any hash differs, or any other out-of-scope path is listed (restore it with `git checkout --` and record `FORMAT-OUT-OF-SCOPE-RESTORED:`), the step "changed files" per R11: record `RESTART: yes` and begin iteration N+1 at this task; otherwise `RESTART: no`. `EXIT_CODE: 0`. +- [x] [P2-T2] Analyze step, iteration N, recorded in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t2-analyze.iter..md`. Run six CMD-ANALYZE calls and transcribe each payload, each with the stated `scan_folders` value: (A) `scan_folders = ["scripts/vscode"]`; (B) `scan_folders = ["tests/scripts/vscode"]`; (C) `scan_folders = ["scripts/vscode/Invoke-MSTestWithCoverage.ps1"]`; (D) `scan_folders = ["scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1"]`; (E) `scan_folders = ["tests/scripts/vscode/Invoke-MSTestWithCoverage.Scope.Tests.ps1"]`; (F) `scan_folders = ["scripts/vscode/Invoke-MSTest.ps1"]`. Then repeat the P2-T1 hash command and `git status --porcelain -uall -- scripts tests` and record both. Acceptance for a passing iteration: run (A)'s integer `N_SCRIPTS_FINAL:` is not greater than `N_SCRIPTS_BASELINE:` from P0-T5 (record the delta); runs (B), (C), (D) and (E) are each `ok: true` (zero findings on every changed file and on the test folder); run (F)'s integer equals `N_INVOKE_MSTEST_BASELINE:` from P0-T5 (original D10); the four hashes equal this iteration's P2-T1 HA values and the porcelain over scripts and tests names only Write Set paths (the step changed no file). The artifact's `EXIT_CODE:` row is run (A) with `ExpectedExitCode: 1`; every other run is recorded on its own named line. Any failed condition is a fix inside the Write Set followed by `RESTART: yes` at P2-T1; no suppression attribute or comment is added. +- [x] [P2-T3] Test step in coverage mode, iteration N, recorded in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t3-test-coverage.iter..md` (this task re-runs the original plan's P2-T3 with the superseded literals stated in the Relationship section). Run CMD-TEST with `scan_folders = ["scripts/dependencies", "scripts/vscode", "tests/scripts/dependencies", "tests/scripts/vscode"]`; read artifacts/pester/pester-junit.xml and record the root `tests`, `failures` and `errors`, the `testsuite` count, and the `tests` and `failures` values of the testsuite whose leaf name is `Invoke-MSTestWithCoverage.Scope.Tests.ps1`; Grep the document for `.jacoco.xml (N substituted) and the Set-Location substitution; record `COVERAGE-ROUTE: C`, `DIRECT_PESTER_EXIT:`, the `PESTER_COUNTS`, `POPULATION_LINE` and `FILE_LINE` lines, `FINAL_POPULATION_LINE_PERCENT:` = 100 times covered over covered plus missed from `POPULATION_LINE` to two decimals, and each production file's percentage as 100 times (total minus uncovered) over total from its `FILE_LINE` line. Then run `git diff --numstat 177b6d78e -- scripts/vscode` (record verbatim), `git diff -U0 177b6d78e -- scripts/vscode/Invoke-MSTestWithCoverage.ps1` (record its plus-side hunk headers; `@@ -277,0 +278,14 @@`, `@@ -296,0 +311,4 @@` and `@@ -386,2 +404,6 @@` are expected, giving changed lines 278 to 291, 311 to 314 and 404 to 409) and `git diff -U0 177b6d78e -- scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1` (record its single hunk header; the file is absent at the base anchor, so every line the JaCoCo document lists for it is a changed line); derive `CHANGED-LINES-UNCOVERED (Invoke-MSTestWithCoverage.ps1):` as the intersection of the entry point's changed lines with its uncovered_lines, written `none` or the line numbers, and `CHANGED-LINES-UNCOVERED (Invoke-MSTestWithCoverage.Scope.ps1):` as its whole uncovered_lines list, written `none` or the numbers; when Invoke-MSTest.ps1 is listed by the numstat, derive the same from the plus-side hunk headers of `git diff -U0 177b6d78e -- scripts/vscode/Invoke-MSTest.ps1`. Afterwards run `git status --porcelain -uall` and, if a line reading ?? coverage.xml is present, remove that one file with git clean -f and the pathspec coverage.xml, and record it. Acceptance for a passing iteration: root `failures` 0 and `errors` 0; root `tests` equals `TESTS_START:` from P0-T6 plus 8, which is 342; the `testsuite` count is 27; the Scope testsuite reports `tests` 22 and `failures` 0; `.md` and check off the two open tasks of the original plan. Acceptance: the artifact tables every iteration from 1 upward with, per iteration, the artifact name and `RESTART:` value of each of P2-T1, P2-T2 and P2-T3 that ran in that iteration, and `not run (restart at P2-T1)` for a step that did not run because an earlier step of the same iteration recorded `RESTART: yes` (iteration 1 is taken from evidence/qa-gates/p2-t1-format.iter1.2026-09-29T09-16.md, p2-t2-analyze.iter1.2026-09-29T09-18.md and p2-t3-test-coverage.iter1.2026-09-29T09-23.md, whose third step recorded `RESTART: yes` as prescribed and not executed); the final iteration is the only one whose three steps all record `RESTART: no` and all meet their passing conditions, and its three artifacts carry the same `iter` token; the artifact records `LOOP-CLOSED: yes`; then, in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/plan.2026-09-28T19-45.md`, the line beginning `- [ ] [P2-T3]` becomes `- [x] [P2-T3]` and the line beginning `- [ ] [P2-T4]` becomes `- [x] [P2-T4]` with no other character of either line changed and no other edit to that file, so that its Grep count of `^- \[ \] \[P` falls from 2 to 0 and its counts of `^- \[x\] \[P2-T3\]` and `^- \[x\] \[P2-T4\]` are each 1 (both counts recorded); `Command: none (reconciliation of the step artifacts) plus two Edit-tool check-offs`; `EXIT_CODE: 0`. If no iteration closes, the artifact records `LOOP-CLOSED: no`, the original plan file is not edited, and the plan outcome is remediation-required. +- [x] [P2-T5] Gate file sizes and untouched neighbors (refreshing the original P2-T5 stem), recorded in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t5-file-size-and-untouched-neighbors..md`. Run `git diff --numstat 177b6d78e -- scripts/vscode tests/scripts/vscode`. Acceptance: every path the numstat lists is one of the four Write Set PowerShell files, and the threshold part file and the helpers file are absent from it; the derived line counts, each recorded with its arithmetic, are: entry point 439 plus added minus deleted, at most 500 (461 expected); Scope part file equal to its added count, at most 120 (104 expected); Scope test file equal to its added count, at most 500 (about 304 expected); Invoke-MSTest.ps1 262 plus added minus deleted, at most 500 (a file absent from the listing is recorded at its base count 262; the bases 439 and 262 are the newline-terminated counts numstat arithmetic uses); Grep over scripts/vscode/Invoke-MSTestWithCoverage.Threshold.ps1 gives count 1 for each of `-lt 80`, `-lt 75`, `required 80% threshold` and `required 75% threshold` (AC3 literals unchanged); `EXIT_CODE: 0`. +- [x] [P2-T6] Lock the footprint (refreshing the original P2-T6 stem), recorded in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t6-scope-lock..md`. Run `git status --porcelain -uall` and `git diff --name-only 177b6d78e -- scripts tests .github .vscode config` (companions: the porcelain span sees untracked and modified paths and the anchored diff sees content changes under the five code and configuration trees). Acceptance: every porcelain line names a Write Set path, a path under the feature folder, a path under the agent-memory tree beneath the .claude directory, or a path under the docs/features/potential/promoted folder, and no porcelain line names a path under scripts/ or tests/ other than the four Write Set PowerShell files; every path the name-only diff lists is one of the four Write Set PowerShell files, and the two Scope files and the entry point are each listed; no porcelain line reads ?? coverage.xml; the artifact records both listings verbatim (the porcelain listing is non-empty by construction and its count is deliberately not asserted); `EXIT_CODE: 0`. +- [x] [P2-T7] Decide AC6 in `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/issue.md` and record `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/regression-testing/p2-t12-ac6-check-off..md` (refreshing the original P2-T12 stem). Evidence read: the final-iteration P2-T2 and P2-T3 artifacts of this plan, the P2-T4 closure, and the original P0-T7 baseline artifact. Acceptance, one of exactly two recorded outcomes: (i) when P2-T4 records `LOOP-CLOSED: yes`, the final P2-T3 records `COVERAGE-ROUTE: C`, `FINAL_POPULATION_LINE_PERCENT:` at or above 80.00 and at or above 94.49 (the original P0-T7 `BASELINE_POPULATION_LINE_PERCENT:`, same route, identical command), the Scope part file at or above 90, and `CHANGED-LINES-UNCOVERED: none` for the entry point, for the Scope part file and, when listed by `git diff --numstat 177b6d78e -- scripts/vscode`, for Invoke-MSTest.ps1, the final P2-T2 met every condition, and additionally (original D10) Invoke-MSTest.ps1 is absent from that numstat or the final P2-T2 run (F) returns `ok: true`, then the AC6 line changes from `- [ ] AC6:` to `- [x] AC6:` with no other character of the line changed, the Grep count of `^- \[x\] AC` over the issue file rises from 6 to 7, and the artifact quotes every figure with its source artifact path; (ii) otherwise the AC6 line is left unchanged, the count stays 6, and the artifact records `AC6-STATUS: PENDING` with the reason (`loop-not-closed`; `below-floor` with the figure; `below-baseline` with both figures; `changed-line-uncovered` with the file and line numbers; `part-file-below-90` with the figure; `analyzer-findings-on-changed-file` naming the file and the count; or `direct-pester-unavailable`), so the plan outcome is reported as remediation-required for AC6 and never as PASS. `EXIT_CODE: 0` in both outcomes; the executor does not edit the AC6 text. +- [x] [P2-T8] Write the refreshed reduced-audit handoff and AC status summary to `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/other/p2-t13-reduced-audit-handoff..md` (refreshing the original P2-T13 stem). Acceptance: the artifact carries the `### Acceptance Criteria Status` block from the `acceptance-criteria-tracking` skill with Source = the issue file, Total 7, Checked off equal to the current Grep count of `^- \[x\] AC` over the issue file (7 after outcome (i) of P2-T7, 6 otherwise), Remaining equal to 7 minus that count, and the remaining item texts (none, or the AC6 text); a list by path of every evidence artifact produced by P0-T1 through P2-T7 of this plan; `COVERAGE-ROUTE: C` with the final iteration number; the statement that the original plan's P2-T3 and P2-T4 were checked off by P2-T4 of this plan (or were not, with the reason); the statement that no commit was made and that the three edited PowerShell files, the issue file, the original plan file, this plan file and the new evidence artifacts are uncommitted in the worktree; the three promotion candidates P-1, P-2 and P-3 named as excluded from this cycle and owed by the orchestrator through the potential-feature lifecycle; `Command: none (handoff record)`; `EXIT_CODE: 0`. +- [x] [P2-T9] Run the committed-evidence-format and host-identifier scans over `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/` (refreshing the original P2-T14 stem), recording `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/evidence/qa-gates/p2-t14-evidence-format-and-host-identifier-scan..md`. Steps: (1) Glob the feature folder for every file with the xml extension and then for every file with the trx extension, each with the recursive pattern written as double-asterisk, slash, asterisk, dot, extension, rooted at the feature folder (both must return no file); (2) Grep the feature folder, output mode count, with the Rust-regex pattern `(?x) (^|[^A-Za-z]) [A-Za-z] : [\\/]` (a drive-letter path; the leading class keeps a URL scheme from matching) and require 0 matches; (2b) read the `hostname` attribute and the `user` property value from artifacts/pester/pester-junit.xml of the final P2-T3 run, Grep the feature folder case-insensitively for each value with regex metacharacters escaped, require 0 matches, and record `HOST-NAME-SCAN: 0 matches` and `ACCOUNT-NAME-SCAN: 0 matches` without transcribing either value; (3) Grep the feature folder with `(?xi) [\\/] Users [\\/]` and require 0 matches; (4) Grep the evidence subfolder of the feature folder for `workspace_root` and require every matching line to carry `` on the same line; (5) write the artifact with the results of (1) through (4); (6) re-run (2), (2b) and (3) after the artifact is written and append `POST-WRITE-RESCAN: 0 matches` only when every count is again 0. AC7 is already checked and is not re-checked here: the Grep count of `^- \[x\] AC` over the issue file is recorded and must equal its P2-T8 value. Acceptance: (1) returns no file; (2), (2b) and (3) return 0 both times; (4) holds; the recorded AC count equals the P2-T8 value; `Command: Grep tool and Glob tool, patterns as quoted`; `EXIT_CODE: 0`. Any match is a fix of the offending artifact (placeholder substitution per R12) followed by a re-run of this task from step (1); this task is the last task of the plan so nothing is written after its rescan. ## Acceptance-Criteria Traceability diff --git a/scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 b/scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 index 2b00d1515..cb9b9a746 100644 --- a/scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 +++ b/scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1 @@ -1,9 +1,9 @@ Set-StrictMode -Version Latest -# Added for issue #928.

The eleven-line conditional that lived in the entry point is now a single advanced function in the path-loaded part file, called unconditionally from one place; the two document-level assertion statements keep their text and order; the scoped arm keeps the same two-literal warning; and the entry point is thinner than before the feature. The predicate gained the CR-2 hardening (validation attributes plus absolute-path guards with specific messages) and the test file gained eight cases that cover the new function directly and the guards negatively. The fourteen original cases are untouched and still prove AC1 to AC5 through the entry point, which is the strongest evidence that the relocation is behavior-preserving. + +The cycle-1 Blocking finding (CR-1) is closed: the CI-equivalent breakpoint run credits every changed production line, and the entry point's file figure is back at its base-anchor value. The premise the fix rests on was measured before the edit (r1-p0-t7). No new defect was found in the relocated code, the guards or the tests. One Non-blocking finding (a pre-existing tooling condition on the canonical hook coverage artifact) and eight Informational notes follow. + +Blocking count: 0. + +## Findings Table + +| Severity | File | Location | Finding | Recommendation | Rationale | Evidence | +|---|---|---|---|---|---|---| +| Non-blocking | artifacts/pester/powershell-coverage.xml (gitignored; produced by the bundled PoshQC test route) | report-level LINE counter | The canonical hook coverage artifact instruments only the `.claude` and `.codex` trees (covered 0, missed 9294; no `scripts/` file named), so it reads 0% for the repository scripts and cannot evidence any PowerShell change.

Using `return` rather than an `else` block keeps the two statements at one indentation level and textually identical to the entry-point originals apart from the parameter name (`$CoberturaXml` for `$processedXmlContent`), which is what the plan's decision R2 required and what AC3's "80 and 75 literals unchanged" and "both assertion calls still run on an unscoped run" clauses need. I confirmed the order (line 102 before 103) and that both are unconditional after the scoped `return`. +- The entry point reaches the function through one unconditional call (line 406) placed exactly where the conditional was: after post-processing (402) and before the first-party report (410). A scoped run therefore still prints the first-party report, writes the projection, runs the reconciliation assertion and writes the trx summary; only the two document-level floor assertions are skipped. That matches the `.DESCRIPTION` text at lines 281 to 283. +- The unscoped CI path is unchanged in effect: `_mstest-coverage.yml` line 95 invokes `-SearchRoot .`; `Join-Path '.'` normalises to the repository root through the predicate; the 80 and 75 literals and their messages in Threshold.ps1 (lines 52, 54, 122, 124) are unchanged; no switch exists to skip the gate. +- Mock resolution from the sibling suites is unaffected by the extra scope depth: the RunSettings, ResultsDirectory and AssemblyDiscovery suites mock `Assert-CoberturaLineCoverageThreshold` (and the branch assertion) at Describe or It scope, and Pester resolves a mock for a call made from a function defined by a dot-source inside the entry point just as it did for the direct call. The 342/342 result includes those suites, which is the operative proof (plan R14). + +### Predicate hardening (lines 8 to 57) + +- `[ValidateNotNullOrEmpty()]` on both parameters plus `IsPathRooted` guards with messages that name the parameter and echo the offending value. The messages contain the input value, which for the entry point is a repository path; that is the established pattern in this script (`Search root not found: $resolvedSearchRoot`, line 327) and the value never reaches a committed artifact. +- The guard removes the predicate's only implicit working-directory dependence (`GetFullPath` on a relative input), which was the CR-2 concern. The `.DESCRIPTION` explains why (ambient state), which is the right kind of comment. +- The four negative tests pin the contract from both ends: It 15 and 16 are controls (empty strings fail before and after, at binding), It 17 and 18 are the RED cases (no exception before, exact message after). The r1-p1-t3 partition (6 failing, 16 passing) is consistent with that design. + +### Entry-point edit (Invoke-MSTestWithCoverage.ps1) + +- The dot-source comment (311 to 312) now states a design reason ("this entry point is its only consumer: it calls the gate once, after post-processing") instead of the change-budget rationale; cycle-1 CR-3 is closed. The gate comment (404 to 405) states why the logic is not here. +- The four-line backtick-continued call mirrors the `Invoke-DotnetCoverageCollection` call shape at 385 to 392, so the style is consistent within the function. +- Line count 461 (was 466 at cycle 1, 439 at the base anchor); 39 lines of headroom under the 500-line limit. + +### Test design (Invoke-MSTestWithCoverage.Scope.Tests.ps1) + +- The direct-function Describe mocks only `Write-Warning` and lets the predicate and both real threshold assertions run against the two in-memory fixtures, so It 21 and 22 assert the exact production messages (`Cobertura line coverage 40% ...`, `Cobertura branch coverage 50% ...`) through the new function, not through a mock. This is the same fixture pair the entry-point cases use, so the two paths are proven equivalent on the same inputs. +- It 20's two `Should -Invoke` assertions (unfiltered count, then filtered content) are the same pattern as It 10 and are needed together: the first proves exactly one warning, the second proves it is the scoped-skip warning naming the search root. +- No temporary file, `TestDrive`, sleep or executable is used; the `$global:LASTEXITCODE` writes inside the collector-seam mocks are the sibling-suite idiom for simulating an exit code and are reset to 0 by the production wrapper before each invocation (entry point line 258). +- File length 306; the r1-p1-t2 diff against HEAD was insertion-only (74 added, 0 deleted at that step), so the fourteen original cases are byte-identical. + +### Toolchain evidence read + +- Format: hashes identical before and after at iteration 2 (p2-t1 iter2); liveness proven (r1-p0-t4). +- Analyze: 0 findings on all three changed files (p2-t2 iter2 runs C, D, E); folder counts equal baseline. +- Test: 342/342 (p2-t3 iter2; JUnit root re-read); RED partition 6/16 (r1-p1-t3) then 22/22 (r1-p1-t6). +- Coverage: population 94.53% against 94.49%; entry point 113/126; part file 13/13; every changed line credited (verified in the JaCoCo document; policy audit section 5). diff --git a/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/feature-audit.2026-09-29T11-15.md b/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/feature-audit.2026-09-29T11-15.md new file mode 100644 index 000000000..1dceb00a1 --- /dev/null +++ b/docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/feature-audit.2026-09-29T11-15.md @@ -0,0 +1,63 @@ +# Feature Audit: coverage-runner-scoped-threshold-and-format (Issue #928) - Remediation Cycle 1 Exit + +- Timestamp label: 2026-09-29T11-15 (assigned without a clock read; see the policy audit header) +- Work mode: minor-audit (issue.md line 12, `- Work Mode: minor-audit`) +- AC source: `docs/features/active/2026-09-28-coverage-runner-scoped-threshold-and-format-928/issue.md`, section `## Acceptance Criteria` only (AC1 to AC7). spec.md and user-story.md are absent by design (Glob over the feature folder confirms) and were not consulted. +- Method: Read, Grep and Glob over the worktree; no command executed (Bash withheld by the caller).

It 10 (249 to 257): `Should -Invoke Write-Warning -Times 1 -Exactly` plus a filtered assertion on `Coverage threshold assertions skipped*` and `*QuickFiler.Test*`. Direct path: It 19 and 20 (163 to 184) call `Assert-CoberturaCoverageThresholdForRun` with the same fixture and a scoped search root; no throw; exactly one warning naming the search root.

Direct path: It 21 and 22 (186 to 204) assert the same two messages through the new function with the repository root as the search root. Literals: Threshold.ps1 read by this review, `-lt 80` line 52, message line 54, `-lt 75` line 122, message line 124, unchanged; P2-T5 counts one each. Both assertion calls run unconditionally on an unscoped run: part file lines 102 and 103, in that order, after the scoped-arm `return` at 100; the entry point reaches them through the single unconditional call at 406 (Grep for `Assert-CoberturaLineCoverageThreshold` in the entry point: 0, so no second path exists). Workflow: P2-T6 name-only diff over `.github` lists nothing; `_mstest-coverage.yml` line 95 still invokes `-SearchRoot . -Configuration Debug`.

It 14 (295 to 305) reads the parsed help and matches `scoped`, `repository root`, `skip`.

Changed production lines: the entry point's `` lists 126 nodes with `ci="0"` on exactly 149, 171, 187, 229, 333, 341, 345, 358, 364, 370, 436, 452, 460, none of which lies in the changed ranges 278 to 291, 311 to 314 or 404 to 409; the changed analyzable lines 313, 406 and 410 read `ci` 2, 1 and 2. The part file's `` lists 13 nodes, all with `ci` at least 1 (the file is entirely new, so every node is a changed line). The pre-remediation document reproduces the defect being fixed (line 408 `mi="2" ci="0"`), so the before/after pair measures the same route.

The sibling suites' `Assert-Cobertura*Threshold` mocks (RunSettings line 415, ResultsDirectory line 198, AssemblyDiscovery lines 138, 143, 157, 162) still intercept the calls now made one scope deeper: all 342 tests pass (plan decision R14). | +| Deterministic test requirements | PASS | No PATH, cwd, profile or network dependence; `$PSScriptRoot`-relative resolution only; the CR-2 guard removes the predicate's only implicit working-directory dependence. | +| Changed-line coverage regression is blocking | PASS | No changed production line is uncovered under the agreed route; entry-point file figure returned to its base-anchor value (113 of 126); see section 5. Cycle-1 finding G-1 is closed. | + +## 5. Test Coverage Detail + +Route: C (direct Pester 5.6.1 run mirroring the CI workflow; the bundled MCP document does not name the changed files, see 1.2.2).

Line 410 (the first-party report) is a pre-existing statement that shifted; it is credited. The 13 uncovered entry-point lines are the base anchor's 13 uncovered lines: 149, 171, 187, 229 unchanged; 315, 323, 327, 340, 346, 352 shifted by 18 to 333, 341, 345, 358, 364, 370; 414, 430, 438 shifted by 22 to 436, 452, 460.

Lines 42 and 46 (the two guard throws) are credited by It 17 and 18; lines 97, 102 and 103 (the warning and the two assertion statements) are credited by It 19 to 22 and by the entry-point cases It 9, 10, 12, 13. The diagnostic gate r1-p0-t7 established the crediting premise before the edit: in a two-file run ordered AssemblyDiscovery then Scope, the four Threshold.ps1 throw lines reached only by the later-sorting suite were credited (uncovered set 11 in the control run, 7 in the ordered run, with 53, 54, 123, 124 removed), and `CONTAINER_ORDER` confirmed the order Pester used. + +Thresholds (uniform tier rule, .claude/rules/quality-tiers.md; CLAUDE.md 80/90 also stated): + +- New file line coverage at least 85% (90% per CLAUDE.md): PASS (100.00%). +- Modified file line coverage at least 85%: PASS (89.68%). +- Modified file no regression on changed lines: PASS (all three changed analyzable lines credited; file figure equal to the base anchor). +- Repo-wide (CI population) at least 85%: PASS (94.53%). +- Repo-wide not below recorded baseline (AC6 clause): PASS (94.53% against 94.49%, identical command). + +## 6.

Gaps and Exceptions + +- G-1 (cycle 1, Blocking): CLOSED. AC6's baseline clause and changed-line clause are both met by the agreed measurement route (section 5). The plan's final QC loop is recorded closed (P2-T4 `LOOP-CLOSED: yes` at iteration 2); the original plan has no unchecked task. +- NB-1 (Non-blocking, pre-existing tooling): the canonical hook coverage artifact at `artifacts/pester/powershell-coverage.xml`, produced by the bundled PoshQC test route, instruments only the `.claude` and `.codex` trees and therefore reads 0% for the repository scripts; it cannot serve as evidence for any branch that changes `scripts/`. This review records FAIL on that artifact row and PASS on the Route C measurement (section 1.2.2). Not caused by this change; disposition non-blocking. Promotion candidate P-4: make the bundled route's coverage path cover `scripts/dependencies` and `scripts/vscode` (or point the hook at the CI-equivalent document). +- I-1 (Informational): `drmoisan` appears in issue.md line 10 (the GitHub issue URL the template requires) and as the `Owner:` field of the two plan files. It is the public repository owner handle, not the Windows account name, the host name or a path; AC7's clause names the developer account name, and the account-name Grep returns 0. +- I-2 (Informational): the part-file header comment (lines 5 to 6) states as fact that "every test file shares one compiled copy of a path-loaded file". The r1-p0-t7 diagnostic measured the observable consequence (a later-sorting suite's hits on a path-loaded part file are credited), not the interpreter mechanism. Recommend softening to "is credited from any test file (measured at issue #928)" on the next edit of the file; the comment's purpose (why the gate lives here) is served either way. +- I-3 (Informational, carried from cycle 1): It 9 carries two assertions (`Should -Not -Throw` and the `Set-Content` count); acceptable, optional split. +- I-4 (Informational, carried; promotion candidate P-3): script-level comment-based help for the entry point, so `Get-Help .\Invoke-MSTestWithCoverage.ps1` surfaces the scoped-run behavior; AC4 is satisfied by the function help. The `.PARAMETER SearchRoot` text still carries the redundant clause "; they are skipped only on a scoped run". +- I-5 (Informational, pre-existing, outside this diff; promotion candidate P-2): tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1 embeds the developer account name in literal fixture paths (Grep for the user-profile prefix in that file: 4 matches at lines 41, 42, 104, 124). +- I-6 (Informational, pre-existing; promotion candidate P-1): the breakpoint under-crediting of entry-point lines reached only by a suite sorting after `Invoke-MSTest.RunSettings.Tests.ps1` remains a property of the four `ParseFile`-importing suites; this change avoided it structurally rather than fixing it. +- I-7 (Informational): CLAUDE.md states 80% line coverage for PowerShell while .claude/rules state 85%; every figure here clears both floors; no literal changed. +- I-8 (Informational): evidence timestamp labels were assigned by the executor and by this review without a clock read (disclosed in each artifact); labels are monotone with the recorded task order and are not used for ordering decisions. +- I-9 (Informational): the `Assert-CoberturaCoverageThresholdForRun` parameters carry `Mandatory` but not `[ValidateNotNullOrEmpty()]`; a mandatory `[string]` already rejects an empty argument at binding, and relative inputs are rejected by the predicate it calls, so behavior is equivalent to the predicate's contract. `[IO.Path]::IsPathRooted` accepts a drive-relative root such as `\repo`; the entry point never produces one (`Resolve-Path` output and a `Join-Path` on it), so no functional exposure exists. +- Not independently verifiable in this session (no git): that the working tree is clean at 408ac211f and that the commit contains no path outside the executor's recorded footprint. The three code files and every feature-folder file were read from the working tree; the P2-T6 porcelain and name-only diff are the executor's evidence. + +## 9. Summary of Changes + +- `scripts/vscode/Invoke-MSTestWithCoverage.Scope.ps1` (new, 104 lines): `Test-CoverageRunIsScoped -RepoRoot -ResolvedSearchRoot` (pure; `[ValidateNotNullOrEmpty()]`; `IsPathRooted` guards; `GetFullPath` normalisation; trailing-separator trim; ordinal case-insensitive equality negated) and `Assert-CoberturaCoverageThresholdForRun -CoberturaXml -RepoRoot -ResolvedSearchRoot` (scoped: one warning naming both roots, return; unscoped: line assertion then branch assertion, unchanged text and order). +- `scripts/vscode/Invoke-MSTestWithCoverage.ps1` (+24/-2 against the base anchor): `.DESCRIPTION` and `.PARAMETER SearchRoot` help on `Invoke-MSTestWithCoverageMain`; dot-source of the Scope part file after the TrxSummary dot-source with a reworded comment; the two direct `Assert-Cobertura*CoverageThreshold` calls replaced by one unconditional `Assert-CoberturaCoverageThresholdForRun` call preceded by a two-line comment. +- `tests/scripts/vscode/Invoke-MSTestWithCoverage.Scope.Tests.ps1` (new, 306 lines): 12 predicate cases (8 equivalence, 4 negative), 4 direct wrapper cases, 3 scoped-run entry-point cases, 2 unscoped-run entry-point cases, 1 help case. +- `scripts/vscode/Invoke-MSTest.ps1`: unchanged (formatter rewrote nothing). +- Documentation: issue.md AC6 check-off (7 of 7 checked), original plan P2-T3 and P2-T4 check-offs, remediation plan check-offs, 21 cycle-1 evidence artifacts, refreshed handoff and hygiene scan. + +## 10.
