## 1. Observation

### O1. Codebase & Layout Inspection
- **Files Inspected**:
  - `client/web_pc/index.html` (395 lines): Declares `<base href="../webapp/">`, `#app-viewport` fixed full-screen layout, dummy hidden `#joystick-stick` DOM guard, dual fluid orb canvases, central action bar (QWER, LMB, RMB, Space, 1-5 flasks), 180×130 minimap with telemetry, collapsible chat dock, and 9-language reactive selector.
  - `client/web_pc/css/pc_main.css` (126 lines): Enforces `overflow: hidden !important; width: 100vw; height: 100vh;` and removes scrollbars across all browsers.
  - `client/web_pc/css/pc_hud.css` (347 lines): Implements fluid orb bezels, action bar slots, cooldown conic overlays, and updated relative atlas path `url('../../webapp/assets/skills/martial_skills_atlas.png')`.
  - `client/web_pc/css/pc_modals.css` (125 lines): Implements PoE2 side-by-side dual-docking modals (Character left-docked at 24px, Inventory right-docked at 24px) leaving the central 2.5D game view clear.
  - `client/web_pc/js/pc_input_controller.js` (272 lines): Click-to-Move, continuous Hold-to-Move drag via `pointermove` and `isoToWorld`, RMB contextmenu suppression and primary skill invocation, QWER skills with key `W` decoupled from movement (`window.keys = {}`), 1-5 survival flasks with timers, Spacebar dodge (0.25s i-frame), and active typing focus exclusion guard.
  - `client/web_pc/js/pc_hud_controller.js` (162 lines): Binds dual fluid orbs via `HudOrbs`, central action bar, minimap via `MinimapHUD`, and real-time FPS/ping telemetry.
  - `client/web_pc/js/pc_main.js` (201 lines): Application orchestration, hover tooltips, modal hotkeys, chat dock toggle, and `FreeExileI18n` subscription on `freeexile:localeChanged`.
  - `tools/serve_web_pc.py` (299 lines): Local test server on port 8089 with defense-in-depth multi-prefix asset fallback routing (`web_pc/css/assets/`, `web_pc/assets/`, `assets/`, `webapp/assets/`).

## 2. Logic Chain

1. **Requirement R1 (Layout & Viewport)**:
   - Evaluated DOM layout and styling. `#app-viewport` uses fixed inset-0 (100vw × 100vh) with `overflow: hidden`.
   - Verified that `.iphone-frame` and `#simulator-bar` are absent from `client/web_pc/`.
   - Tested 16:9 (1920×1080), 16:10 (1920×1200), and 21:9 Ultrawide (2560×1080) viewports via Playwright. Zero horizontal or vertical scrollbars occurred. Requirement R1 is fully satisfied.

2. **Requirement R2 (PC Controls & Input Kinematics)**:
   - Evaluated `pc_input_controller.js`. LMB click and pointer drag correctly call `isoToWorld` and update `player.destination = { wx, wy, active: true }`.
   - `canvas_renderer.js` checks `mx === 0 && my === 0 && !joystickActive && player.destination && player.destination.active`, advancing character kinematics until `destDist <= 0.22`.
   - RMB prevents context menu and triggers primary combat skill.
   - Key `W` is decoupled by keeping `window.keys['w']` falsy and directly invoking `doThunder()` upon keydown.
   - Spacebar triggers `doDodge()`, entering the 0.25s i-frame window.
   - Survival flasks 1–5 activate corresponding potion effects and trigger cooldown sweeps.
   - Active typing focus on `#chat-input` or textareas prevents gameplay hotkey intercept. Requirement R2 is fully satisfied.

3. **Requirement R3 (Grimdark Action HUD & Modals)**:
   - Verified symmetrical Life and Qi globes with animated sinusoidal fluid levels and numerical overlays.
   - Central Action Bar features 5 flask slots, 4 skill slots (Q, W, E, R), 2 mouse slots (LMB, RMB), Space dodge slot with charge counter (3), and 360° radial cooldown sweeps.
   - Minimap (180×130) displays current zone name, real-time player world coordinates, cardinal directions (N/S/E/W), and telemetry.
   - Collapsible chat dock supports 6 channels, message ticker, and HMAC item inspection.
   - Side-by-side dual docking allows Character Sheet (left) and Inventory (right) to mount concurrently without obstructing the central view.
   - Action bar skill icon path was corrected by `worker_iter3` to `../../webapp/assets/skills/martial_skills_atlas.png`, and empirical inspection confirmed the atlas decodes with `naturalWidth: 1024, naturalHeight: 1024`. Requirement R3 is fully satisfied.

4. **Requirement R4 (Core Engine Integration & Zero Mobile Regression)**:
   - `<base href="../webapp/">` enables asset reuse without duplication.
   - `FreeExileI18n` translation occurs in-place upon `freeexile:localeChanged` with zero page reloads across all 9 canonical languages (`vi`, `en`, `zh`, `ja`, `ko`, `th`, `de`, `ru`, `es`).
   - `tools/serve_web_pc.py` implements defense-in-depth routing for all asset prefix permutations.
   - Zero files in `client/webapp/` were modified, and all mobile tests passed. Requirement R4 is fully satisfied.

5. **Integrity & Quality Audit**:
   - Inspected source code for hardcoded test bypasses, mock data cheating, or facades: none found.
   - All tests execute real browser instances, compute actual isometric raycasting, and test live DOM elements.

## 3. Caveats

- **No Caveats**: All 4 requirements from `ORIGINAL_REQUEST.md` (§ `## 2026-10-02T05:17:43Z`) are 100% implemented, verified with live commands, and zero mobile regressions exist.

---

## 4. Conclusion

The FreeExile Dedicated PC Desktop Full-Screen Web Client (`client/web_pc/`) is complete, robust, cleanly integrated, and fully compliant with project standards. All iteration defects (including the Iteration 2 CSS relative asset path 404) have been eliminated.

**Final Verdict**: **APPROVE**

## 5. Verification Method

To independently verify this verdict:

```powershell
# 1. Run live clean load diagnostic (verifies 0 page errors, 0 console errors)
python .agents/teamwork/reviewer_iter2_1/clean_load_diagnostic.py

# 2. Run skill icon image dimension verification (verifies naturalWidth == 1024)
python .agents/teamwork/worker_iter3/verify_skill_icons.py

# 3. Run Playwright E2E test suite (19 tests)
pytest tests/e2e/test_pc_desktop_client_e2e.py -v

# 4. Run PC client unit tests and mobile config tests (45 tests)
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

# 5. Run hygiene linters
python tools/lint/check_code_and_doc_hygiene.py
python tools/lint/check_i18n_hygiene.py --strict
```

### Invalidation Conditions
- Any occurrence of `Failed to load resource ... 404` or uncaught exceptions in the browser console.
- `#skill-q .skill-icon` image failing to decode or returning `naturalWidth == 0`.
- Any modification to files within `client/webapp/`.
- Any test failure in `tests/e2e/test_pc_desktop_client_e2e.py` or unit test suites.
