# PR-1 Frontend/Test Implementation Status

Date: 2026-02-18
Scope: PR-1 high-risk JavaScript findings only (`js/regex/missing-regexp-anchor`, `js/insecure-temporary-file`)

## Files In Scope (HR-013..HR-021)

- `frontend/src/components/__tests__/SecurityHeaderProfileForm.test.tsx`
- `frontend/src/pages/__tests__/ProxyHosts-progress.test.tsx`
- `tests/tasks/import-caddyfile.spec.ts`
- `tests/security-enforcement/zzz-caddy-imports/caddy-import-cross-browser.spec.ts`
- `tests/fixtures/auth-fixtures.ts`

## Diff Inspection Outcome

Current unstaged frontend/test changes already implement the PR-1 high-risk remediations:

- Regex anchor remediation applied in all PR-1 scoped test files:
  - moved from unanchored regex patterns to anchored expressions for the targeted cases.
- Secure temporary-file remediation applied in `tests/fixtures/auth-fixtures.ts`:
  - replaced fixed temp paths with `mkdtemp`-scoped directory
  - set restrictive permissions (`0o700` for dir, `0o600` for files)
  - lock/cache writes use explicit secure file modes
  - cleanup routine added for temp directory lifecycle

No additional frontend/test code edits were required for PR-1 scope.

## Commands Run

1. Inspect unstaged frontend/test diffs
   - `git --no-pager diff -- frontend tests`

2. Preflight (advisory in this run; failed due missing prior coverage artifacts)
   - `bash scripts/local-patch-report.sh`
   - Result: failed
   - Error: `frontend coverage input missing at /projects/Charon/frontend/coverage/lcov.info`

3. Targeted frontend unit tests (touched files)
   - `cd frontend && npm ci --silent`
   - `cd frontend && npm run test -- src/components/__tests__/SecurityHeaderProfileForm.test.tsx src/pages/__tests__/ProxyHosts-progress.test.tsx`
   - Result: passed
   - Summary: `2 passed`, `19 passed tests`

4. Targeted Playwright tests (touched files)
   - `PLAYWRIGHT_HTML_OPEN=never PLAYWRIGHT_COVERAGE=0 PLAYWRIGHT_BASE_URL=http://127.0.0.1:8080 PLAYWRIGHT_SKIP_SECURITY_DEPS=1 npx playwright test --project=firefox tests/tasks/import-caddyfile.spec.ts tests/security-enforcement/zzz-caddy-imports/caddy-import-cross-browser.spec.ts`
   - Result: passed
   - Summary: `21 passed`

5. Type-check relevance check
   - `get_errors` on all touched TS/TSX files
   - Result: no errors found in touched files

6. CI-aligned JS CodeQL scan
   - Task: `Security: CodeQL JS Scan (CI-Aligned) [~90s]`
   - Result: completed
   - Coverage line: `CodeQL scanned 347 out of 347 JavaScript/TypeScript files in this invocation.`
   - Output artifact: `codeql-results-js.sarif`

7. Rule presence verification in SARIF (post-scan)
   - searched `codeql-results-js.sarif` for:
     - `js/regex/missing-regexp-anchor`
     - `js/insecure-temporary-file`
   - Result: no matches found for both rules

## PR-1 Frontend/Test Status

- `js/regex/missing-regexp-anchor`: remediated for PR-1 scoped frontend/test files.
- `js/insecure-temporary-file`: remediated for PR-1 scoped fixture file.
- Remaining findings in SARIF are outside PR-1 frontend/test scope (PR-2 items).

## Remaining Blockers

- No functional blocker for PR-1 frontend/test remediation.
- Operational note: `scripts/local-patch-report.sh` could not complete in this environment without pre-generated coverage inputs (`backend/coverage.txt` and `frontend/coverage/lcov.info`).
