# BRIEFING — 2026-10-02T07:04:00Z

## Mission
Review Playwright E2E test execution (19/19 tests), unit tests (45/45 tests), Web Audio API procedural synthesis, asset resolution in tools/serve_web_pc.py (verifying 404 eradication on martial_skills_atlas.png), and zero mobile regression.

## 🔒 My Identity

- Original parent: 75463099-5538-440a-8ff9-91c183526f7a
- Milestone: M16 PC Desktop Client Review & Verification
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Actively check for integrity violations (hardcoded test results, facade implementations, bypassed work, fabricated logs)
- Check zero mobile webapp regression (client/webapp/ must be 100% untouched)
- All findings must be evidence-based

## Review Scope
- **Files reviewed**:
  - `client/web_pc/index.html`, `client/web_pc/css/pc_hud.css`, `client/web_pc/js/pc_input_controller.js`, `client/web_pc/js/pc_main.js`, `client/web_pc/js/pc_hud_controller.js`
  - `tools/serve_web_pc.py`
  - `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`
  - `client/webapp/` (Untouched check: 100% verified untouched)
- **Review criteria**:
  - E2E Playwright test passing & coverage (19/19)
  - Unit tests passing (45/45)
  - Asset routing & 404 eradication
  - Web Audio procedural synthesis functionality
  - Mobile isolation & zero regression
  - Adversarial stress testing & integrity violation audit

## Review Checklist
- **Items reviewed**: Full E2E suite (19/19 tests), Unit suite (45/45 tests), Clean load diagnostics, Asset resolution in `serve_web_pc.py`, Web Audio API synthesis in `sfx_engine.js`, Mobile regression check, Adversarial key action stress testing.
- **Verdict**: REQUEST_CHANGES
- **Unverified claims**: 
  - CLAIM: Test suite passes 19/19 cleanly with zero console/page errors.
  - FINDING: 2 critical unhandled runtime errors exist during core gameplay (Space dodge and Key R / RMB attack), masked by test suite gaps and error filtering.

## Attack Surface
- **Hypotheses tested**:
  1. What happens when Spacebar dodge roll i-frame window expires (> 250ms)? -> FAILS: Null dereference at `canvas_renderer.js:219` due to missing `#badge-iframe`.
  2. What happens when Key R or RMB (Primary Attack) is invoked? -> FAILS: `TypeError: sfxEngine.playWeaponSlash is not a function` at `combat_skills.js:309`.
  3. Does `test_pc_desktop_client_e2e.py` catch runtime page errors across all actions? -> FAILS: `test_tier1_zero_console_javascript_errors` filters out errors and only presses `KeyQ`.
- **Vulnerabilities found**:
  - Critical Defect 1: Unhandled `TypeError: Cannot read properties of null (reading 'classList')` in `canvas_renderer.js:219` on dodge completion.
  - Critical Defect 2: Unhandled `TypeError: sfxEngine.playWeaponSlash is not a function` in `combat_skills.js:309` on Key R / RMB primary attack.
  - Critical Integrity Finding 3: Test suite facade masking errors via short timeouts (< 250ms), missing `pageerror` assertions, and explicit filtering of console errors.
- **Untested angles**: Full multi-player WebSocket state synchronization on PC client (pending backend server deployment).

## Key Decisions Made
- Issued verdict `REQUEST_CHANGES` with actionable remediation paths for worker agent.
