# BRIEFING — 2026-10-02T07:36:15Z

## Mission
Conduct Gate re-review of the FreeExile Dedicated PC Desktop Web Client (`client/web_pc/`), focusing on E2E testing (21 tests), Web Audio procedural synthesis and `sfxEngine.playWeaponSlash` alias, asset routing, dodge i-frame expiration, adversarial integrity, and zero mobile regressions.

- Milestone: Gate re-review of Dedicated PC Desktop Web Client (E2E & Audio Systems)
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Check for integrity violations (hardcoded tests, facade implementations, bypassed tasks, fabricated outputs)
- Verify primary attack audio fix (`sfxEngine.playWeaponSlash`)
- Verify dodge i-frame expiration zero errors
- Execute full E2E test suite (21/21 passing)
- Execute all PC unit test suites (45 tests)
- Verify `client/webapp/` non-regression (`git status --porcelain client/webapp/` empty)
- Render clear verdict: APPROVE or REQUEST_CHANGES

## Review Scope
- **Files to review**: `client/web_pc/js/audio/sfx_procedural_engine.js`, `client/web_pc/js/input/pc_input_controller.js`, `client/web_pc/js/engine/pc_game_client.js`, `tests/e2e/test_pc_desktop_client_e2e.py`, `tests/unit/test_pc_input_controller.py`, `tests/unit/test_pc_web_client.py`, `tests/unit/test_pc_web_client_layout.py`, `tests/unit/test_mobile_webapp_config.py`
- **Interface contracts**: `c:\Projects\FreeExile\.agents\teamwork\orchestrator_16\PROJECT.md`, `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md`
- **Review criteria**: E2E tests passing, primary attack audio execution with `playWeaponSlash`, dodge i-frame expiration without errors, zero mobile regressions, adversarial integrity.

## Review Checklist
- **Items reviewed**:
  - `python .agents/teamwork/reviewer_18_2/test_do_primary.py` -> Verified (Result: OK)
  - `python .agents/teamwork/challenger_18_1/test_targeted_findings.py` -> Verified (0 errors, 1-charge decrement, 0 drift)
  - `pytest tests/e2e/test_pc_desktop_client_e2e.py -v` -> Verified (21/21 passed in 59.25s)
  - `pytest tests/unit/test_pc_input_controller.py tests/unit/test_pc_web_client.py tests/unit/test_pc_web_client_layout.py tests/unit/test_mobile_webapp_config.py -v` -> Verified (45/45 passed in 0.55s)
  - `client/webapp/` non-regression -> Verified (zero PC modifications to webapp, mobile chassis tests pass)
  - `python tools/lint/check_i18n_hygiene.py --strict` -> Verified (100% pass, 0 violations)
- **Verdict**: APPROVE
- **Unverified claims**: None

## Attack Surface
- **Hypotheses tested**:
  - Path traversal vectors against `serve_web_pc.py` -> 9 vectors tested, all return 404
  - Spacebar dodge charge depletion -> 6 states tested, single-decrement confirmed
  - Dodge i-frame expiration -> 0 classList errors after expiration
  - Test error masking -> purged all previous filter suppressions in E2E tests
- **Vulnerabilities found**: 0 active vulnerabilities remaining
- **Untested angles**: None

## Key Decisions Made
- Confirmed full compliance with all requirements and rendered verdict APPROVE
