+# PR-2 Implementation Status (Phase 3)
+
+Date: 2026-02-18
+Branch: `feature/beta-release`
+
+## Scope
+Quality-only cleanup for:
+- `js/unused-local-variable` (Matrix B affected frontend/tests/util files)
+- `js/automatic-semicolon-insertion`
+- `js/comparison-between-incompatible-types`
+
+Explicit files in request:
+- `tests/core/navigation.spec.ts`
+- `frontend/src/pages/__tests__/ProxyHosts-bulk-acl.test.tsx`
+- `frontend/src/components/CredentialManager.tsx`
+
+## Files Changed
+- `docs/reports/pr2_impl_status.md`
+
+No frontend/test runtime code changes were required in this run because CI-aligned JS CodeQL results for the three target rules were already `0` on this branch before edits.
+
+## Findings (Before / After)
+
+### Matrix B planned baseline (from `docs/plans/current_spec.md`)
+- `js/unused-local-variable`: **95**
+- `js/automatic-semicolon-insertion`: **4**
+- `js/comparison-between-incompatible-types`: **1**
+
+### CI-aligned JS CodeQL (this implementation run)
+Before (from `codeql-results-js.sarif` after initial CI-aligned scan):
+- `js/unused-local-variable`: **0**
+- `js/automatic-semicolon-insertion`: **0**
+- `js/comparison-between-incompatible-types`: **0**
+
+After (from `codeql-results-js.sarif` after final CI-aligned scan):
+- `js/unused-local-variable`: **0**
+- `js/automatic-semicolon-insertion`: **0**
+- `js/comparison-between-incompatible-types`: **0**
+
+## Validation Commands + Results
+
+1) `npm run lint`
+Command:
+- `cd /projects/Charon/frontend && npm run lint`
+
+Result summary:
+- Completed with **1 warning**, **0 errors**
+- Warning (pre-existing, out-of-scope for PR-2 requested rules):
+  - `frontend/src/context/AuthContext.tsx:177:6` `react-hooks/exhaustive-deps`
+
+2) `npm run type-check`
+Command:
+- `cd /projects/Charon/frontend && npm run type-check`
+
+Result summary:
+- Passed (`tsc --noEmit`), no type errors
+
+3) Targeted tests for touched suites/files
+Commands:
+- `cd /projects/Charon/frontend && npm test -- src/pages/__tests__/ProxyHosts-bulk-acl.test.tsx`
+- `cd /projects/Charon && npm run e2e -- tests/core/navigation.spec.ts`
+
+Result summary:
+- Vitest: `13 passed`, `0 failed`
+- Playwright (firefox): `28 passed`, `0 failed`
+
+4) CI-aligned JS CodeQL task + rule counts
+Command:
+- VS Code Task: `Security: CodeQL JS Scan (CI-Aligned) [~90s]`
+
+Result summary:
+- Scan completed
+- `codeql-results-js.sarif` generated
+- Target rule counts after scan:
+  - `js/unused-local-variable`: `0`
+  - `js/automatic-semicolon-insertion`: `0`
+  - `js/comparison-between-incompatible-types`: `0`
+
+## Remaining Non-fixed Findings + Disposition Candidates
+- For the three PR-2 target CodeQL rules: **none remaining** in current CI-aligned JS scan.
+- Candidate disposition for Matrix B deltas already absent in this branch: **already-fixed** (resolved prior to this execution window on `feature/beta-release`).
+- Non-CodeQL note: lint warning in `frontend/src/context/AuthContext.tsx` (`react-hooks/exhaustive-deps`) is a separate quality issue and can be handled in a follow-up quality PR.
+
+## Closure Note
+- Status: **Closed (Phase 3 / PR-2 target scope complete)**.
+- Target rule outcome: `js/unused-local-variable`, `js/automatic-semicolon-insertion`, and `js/comparison-between-incompatible-types` are all `0` in current CI-aligned JS CodeQL output.
+- Validation outcome: lint/type-check/targeted tests passed for this slice; one non-blocking lint warning remains out-of-scope.
+- Supervisor outcome: approved for Phase 3 closure (`docs/reports/pr2_supervisor_review.md`).
