# 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`).
