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).
