## 1. OBSERVATION

Direct static code examination, AST syntax parsing, test suite execution, and line hygiene audits yielded the following verifiable facts:

### 1.1. Static Code Analysis & Authenticity

1. **`client/webapp/js/ui/hud_orbs.js` (305 lines)**:
   - Line 7: Declares `export class HudOrbs`.
   - Lines 34–39: Specifies high-DPI Canvas constants (`CANVAS_SIZE = 180`, `ORB_RADIUS = 78`, `CENTER_X = 90`, `CENTER_Y = 90`, `LERP_SPEED = 8.0`, `LOW_HP_THRESHOLD = 0.25`).
   - Lines 99–105: Smooth damping via lerp:
     ```javascript

     this.displayedHp += (safeHp - this.displayedHp) * lerpFactor;
     this.displayedMana += (safeMana - this.displayedMana) * lerpFactor;
     ```
   - Lines 110–114: Low HP detection triggering `.orb-low-pulse`, `#life-orb-warning`, and `#hud-low-hp-vignette` when `safeHp > 0 && hpRatio < 0.25`.
   - Lines 171–184: Real Canvas 2D sinusoidal wave mathematics:
     ```javascript
     const waveAmp = (4.0 + (isLowHp ? 2.5 : 0)) * edgeDampening;
     ctx.beginPath();
     ctx.moveTo(0, h);
     const startWave = Math.sin(0 * 0.05 + time * 3.0) * waveAmp;
     ctx.lineTo(0, baseY + startWave);
     for (let x = 0; x <= w; x += 3) {
       const wave = Math.sin(x * 0.05 + time * 3.0) * waveAmp
                  + Math.cos(x * 0.03 - time * 1.6) * (waveAmp * 0.35);
       ctx.lineTo(x, baseY + wave);
     }
     ```

   - Lines 41–60: Default slot registration: Potion (4), Skill 1 (Q/1), Skill 2 (W/2), Skill 3 (E/3), Skill 4 (R/4), Primary Attack (LMB/1), Dodge Roll (Space).
   - Lines 177–187: Continuous `requestAnimationFrame` update loop computing precise delta times:
     ```javascript
     const dt = Math.min(0.1, (now - this.lastFrameTime) / 1000);
     ```
   - Lines 213–236: Genuine radial sweep computation setting `--cooldown-sweep`:
     ```javascript
     const progress = 1.0 - (slot.cooldownRemaining / Math.max(0.001, slot.cooldownTotal));
     const sweepDeg = (clamped * 360).toFixed(1);
     overlay.style.setProperty('--cooldown-sweep', `${sweepDeg}deg`);
     ```
   - Lines 250–265: 0.25s luminous ready pulse trigger (`.is-ready-pulse`) and blocked feedback shake (`.is-cooldown-blocked` with haptic `[15, 30, 15]`).
   - Lines 125–136: Multi-charge support (e.g., Dodge Roll 3 charges).
   - Zero hardcoded test return values, zero facade stubs.

3. **`client/webapp/css/hud_skills.css` (194 lines)**:
   - Lines 127–141: Dynamic conic radial cooldown sweep:
     ```css
     background: conic-gradient(
       from 0deg,
       transparent 0deg,
       transparent var(--cooldown-sweep, 0deg),
       rgba(251, 191, 36, 0.95) var(--cooldown-sweep, 0deg),
       rgba(251, 191, 36, 0.95) calc(var(--cooldown-sweep, 0deg) + 2deg),
       rgba(5, 5, 8, 0.82) calc(var(--cooldown-sweep, 0deg) + 2deg),
       rgba(5, 5, 8, 0.82) 360deg
     );
     ```
   - Lines 57–63: `@keyframes crimsonHeartbeat`.
   - Lines 152–156: `@keyframes skill-ready-pulse`.
   - Lines 163–167: `@keyframes skill-blocked-shake`.
   - Lines 186–193: Responsive ergonomic scaling for mobile viewports (`@media (max-width: 640px)`).

4. **`client/webapp/js/engine/joystick.js` (172 lines)**:
   - Lines 14–15: `const DEAD_ZONE = 0.15; let activePointerId = null;`.
   - Lines 75–83: Dead-zone threshold clamping:
     ```javascript
     if (normDist <= DEAD_ZONE) {
       player.dirX = 0;
       player.dirY = 0;
       ...
       return;
     }
     const effectiveDist = Math.min(1.0, (normDist - DEAD_ZONE) / (1.0 - DEAD_ZONE));
     ```
   - Lines 110–130: W3C PointerEvents integration:
     - Uses `e.pointerId`, `activePointerId`, `joystickZone.setPointerCapture(e.pointerId)`, and `joystickZone.releasePointerCapture(e.pointerId)`.
     - Multi-touch isolation prevents secondary touch taps from hijacking or resetting joystick movement.
   - Lines 131–147: Backward compatibility fallbacks for legacy touch events.

5. **`client/webapp/index.html` (199 lines)**:
   - Lines 106–123: Dual fluid orbs container (`#hud-orbs-container`, `#life-orb-canvas`, `#mana-orb-canvas`, `#hud-low-hp-vignette`).

   - Crucial regression preservation: `#skill-fire`, `#skill-thunder`, `#skill-frost`, `#skill-dodge`, `#badge-iframe` are retained verbatim.

6. **`client/webapp/js/engine/combat_skills.js` (495 lines)**:
   - Line 281: `var dodgeCharges = 3; window.dodgeCharges = dodgeCharges;`.
   - Lines 300–318: `doPrimaryAttack()` with cooldown trigger on slot `'0'`.

### 1.2. Verification Commands & Results

1. **Dedicated Unit Tests (`pytest tests/unit/test_hud_orbs_and_skill_bar.py -v`)**:
   - Result: `13 passed in 0.10s`.
   - All 13 tests passed covering DOM elements, sinusoidal wave math, low HP pulses, retina spec, action slots, controller public API, canonical skills map, conic-gradient sweeps, PointerEvents, dead-zone clamping, and line cap hygiene.

2. **Mobile WebApp Regression Tests (`pytest tests/unit/test_mobile_webapp_config.py -v`)**:
   - Result: `15 passed in 0.16s`.
   - Confirms zero regressions across mobile native viewport, joystick zone, safe areas, combat buttons, and language integration.

3. **Visceral Audio Engine Integration (`pytest tests/unit/test_visceral_audio_engine.py -v`)**:
   - Result: `15 passed in 1.95s`.

4. **JavaScript Syntax Verification (`node -c ...`)**:
   - Command: `node -c client/webapp/js/ui/hud_orbs.js client/webapp/js/ui/skill_bar_controller.js client/webapp/js/engine/joystick.js client/webapp/js/engine/combat_skills.js`
   - Result: Exit code 0, zero syntax errors.

5. **Code & Documentation Hygiene Audit (`python tools/lint/check_code_and_doc_hygiene.py --strict`)**:
   - Result: Exit code 0.
   - `✅ KẾT QUẢ: TOÀN BỘ MÃ NGUỒN VÀ TÀI LIỆU TUÂN THỦ HARD CAP HYGIENE!`.
   - `hud_orbs.js` (305 lines $\le 350$ soft cap).
   - `skill_bar_controller.js` (340 lines $\le 350$ soft cap).
   - `hud_skills.css` (194 lines $\le 350$ soft cap).
   - `joystick.js` (172 lines $\le 350$ soft cap).
   - `index.html` (199 lines $\le 200$ soft cap, $\le 400$ hard cap).
   - `combat_skills.js` (495 lines $\le 500$ hard cap).

6. **E2E Suite Baseline Transition (`pytest tests/e2e/test_poe2_ui_animation_vfx_e2e.py -v`)**:
   - Result: 32 passed, 5 xfailed, 4 xpassed, 1 failed in 0.68s.
   - All 4 Milestone 1 baseline checks successfully flipped from `XFAIL` to `XPASS`:
     * `test_f01_dual_orbs_module_baseline` -> `XPASS`
     * `test_f02_skill_bar_controller_module_baseline` -> `XPASS`
     * `test_f03_f04_hud_skills_css_baseline` -> `XPASS`
     * `test_f09_dodge_charges_budget_baseline` -> `XPASS`
   - The 1 failed test (`test_f03_f04_cooldown_sweep_and_flash_spec`) failed due to root-level documentation clobbering:
     * Line 114: `infra_text = (PROJECT_ROOT / "TEST_INFRA.md").read_text(encoding="utf-8")`
     * At 2026-10-01 07:57:23 AM, a parallel subagent working on Chat Architecture (`test_writer_chat_e2e_1` / `worker_chat_m1_1`) overwrote `TEST_INFRA.md` with the Chat System specification, displacing the UI/VFX specification strings (`"conic"`, `"0.25s"`).
     * The actual stylesheet `client/webapp/css/hud_skills.css` is 100% genuine and verified via `test_f03_f04_hud_skills_css_baseline` (`XPASS`).

## 2. LOGIC CHAIN

1. **Verification of User Constraints**:
   `ORIGINAL_REQUEST.md` (§ 2026-10-01T00:31:10Z) mandates `Integrity mode: development`. Under Development Mode, the forensic checks focus on detecting hardcoded test results, facade implementations, and fabricated verification artifacts.
2. **Analysis for Prohibited Patterns**:
   - *Hardcoded test results*: Direct inspection of `hud_orbs.js`, `skill_bar_controller.js`, `joystick.js`, and `combat_skills.js` confirms zero instances of hardcoded test strings or dummy constants.
   - *Facade implementations*: All modules execute genuine runtime logic: Canvas 2D liquid dynamics with sinusoidal wave equations, `requestAnimationFrame` delta time loops driving 360° `conic-gradient` CSS custom property updates, and W3C PointerEvents with pointer capture and $> 0.15$ dead-zone mathematical remapping.
   - *Fabricated outputs*: No fake logs or pre-populated attestation artifacts were introduced.
   - *Self-certifying tests*: `test_hud_orbs_and_skill_bar.py` tests genuine DOM elements, classes, mathematical functions, and line count boundaries.
3. **Behavioral Empirical Validation**:
   - 13/13 dedicated unit tests pass.
   - 15/15 mobile configuration tests pass.
   - 15/15 visceral audio tests pass.
   - 4 Milestone 1 E2E tests transition from `XFAIL` to `XPASS`.
   - Node.js syntax compiler confirms 0 syntax errors across all 4 modified JavaScript files.
4. **Hygiene & Architectural Boundaries**:
   `check_code_and_doc_hygiene.py --strict` validates that zero Hard Cap limits are violated across the entire workspace. All delivered files respect soft and hard caps.

---

## 3. CAVEATS

1. **Shared Root `TEST_INFRA.md` Concurrency Drift**:
   In `test_poe2_ui_animation_vfx_e2e.py`, test `test_f03_f04_cooldown_sweep_and_flash_spec` inspects the root documentation file `TEST_INFRA.md`. Because multiple parallel milestone teams share the single repository root, another subagent working on the Chat System task overwrote `TEST_INFRA.md` with chat architecture specifications. This is an artifact of multi-agent concurrency on a shared documentation file, not an integrity violation or defect in worker's code deliverables.
2. **Upcoming Milestones Baseline Status**:
   In `test_poe2_ui_animation_vfx_e2e.py`, 5 tests remain `XFAIL` as planned for future milestones (`test_f06_five_phase_machine_baseline`, `test_f07_hit_stop_engine_baseline`, `test_f08_weapon_swing_catalog_baseline`, `test_f17_telegraph_renderer_baseline`, `test_f19_zero_allocation_vfx_pool_baseline`).

---

## 4. CONCLUSION

The work product delivered by `worker_m1_1_gen2` is authentic, complete, robust, and free of any shortcuts, facades, or integrity violations.
- Sinusoidal Canvas 2D liquid simulation operates with genuine mathematics.
- Radial cooldown sweep operates with genuine conic-gradient and `requestAnimationFrame` timing.
- Virtual joystick operates with genuine W3C PointerEvents and $> 0.15$ dead-zone clamping.
- All regression constraints and hygiene limits are strictly satisfied.

**Final Gate Verdict**: **CLEAN** (Approved).
