## 1. Executive Summary

This independent forensic integrity audit was conducted on Worker 2's remediated deliverables following Reviewer 1's findings. The audit evaluated:
1. **Probe Authenticity & Logic**: Verification that the combat input buffer probe, chunk slot inspector, player movement kinematic test, and modal settings pause/unpause lifecycle test in `tools/qa/run_browser_qa_suite.py` evaluate authentic in-page state with zero hardcoded metrics or fabricated outcomes.
2. **Dynamic Runtime Execution**: Verification that the test suite runs genuine Playwright automation driving a headless Chromium browser against `http://127.0.0.1:8088/index.html` under `--strict` mode without crashing.
3. **Telemetry & Documentation Consistency**: Full synchronization between empirical runtime telemetry (`docs/qa/reports/telemetry/qa_browser_telemetry.json`), departmental bug report `QA-BUG-CLI-20261002-03.md`, and master `QA_EXECUTIVE_SUMMARY.md`.
4. **Code & i18n Hygiene**: Verification of line caps, function complexity caps, and zero hardcoded localization strings via project quality gates.

**Final Binary Verdict: CLEAN** (0 integrity violations, 0 fabricated metrics, 100% genuine Playwright automation, 100% hygiene compliance).

## 2. Phase-by-Phase Forensic Checks

### Phase 1: Source Code Forensic Analysis (Static)

| Forensic Check | Scope / Target | Result | Evidence / Details |
| :--- | :--- | :---: | :--- |
| **Hardcoded Output Detection** | `tools/qa/run_browser_qa_suite.py` | **PASS (CLEAN)** | All assertions and telemetry extractions query live DOM elements (`#hud-ping`, `#modal-settings`, `#overlay-pause`, `#txt-char-name`, `#chat-send-btn`) and runtime JS instances (`window.__qaTelemetry`, `window.player`, `window.skillBarController`, `window.defaultTileMapRenderer`, `window.BiomeTextureManager`). Zero hardcoded constants or simulated passes. |
| **Facade Implementation Detection** | `tools/qa/run_browser_qa_suite.py` & `tools/qa/qa_harness_utils.py` | **PASS (CLEAN)** | No dummy/mock wrappers or stub functions returning pre-canned values. Real Playwright methods (`page.evaluate`, `page.click`, `page.keyboard.press`, `page.set_viewport_size`, `page.screenshot`, `page.wait_for_function`) are executed. |
| **Pre-Populated Artifact Detection** | `docs/qa/reports/telemetry/` | **PASS (CLEAN)** | Running the test suite overwrites `qa_browser_telemetry.json` with fresh timestamps (e.g. `2026-10-02T17:41:29Z`), variable frame times (min FPS 3.8, avg FPS 33.6, p99 264.3ms), dynamic player displacement (2.1255 units), variable memory heap values (21.08 MB used), and freshly captured screenshots. |
| **Input Buffer Probe Logic Verification** | `test_r1_input_buffering_and_sync` | **PASS (CLEAN)** | The previous boolean inversion bug in Iteration 1 was resolved. Probe logic: `isQueued = queueSize > 0`, `droppedOnLock = !isQueued`, `lockBypassed = Boolean(slotFired)`. Because `SkillBarController` possesses no input queue (`queueSize === 0`), the probe authentically registers `queued: false`, `dropped_on_lock: true`, `queue_size: 0`, and `lock_bypassed: true`. This matches both the actual code behavior and Section 6 of `QA-BUG-CLI-20261002-03.md`. |
| **TileMapRenderer Slot Count Verification** | `test_r3_biome_traversal` | **PASS (CLEAN)** | The probe queries the runtime instance `window.defaultTileMapRenderer?.slots?.length || window.TileMapRenderer?.instance?.slots?.length || 0`, correctly reading the 8 pre-allocated `ChunkSlot`s (`MAX_SLOTS = 8`) in `client/webapp/js/engine/tile_map_renderer.js:99`, rather than querying the static constructor which previously returned `undefined`. |
| **Player Movement Kinematic Test Verification** | `test_r1_player_movement` | **PASS (CLEAN)** | Playwright dispatches `page.click("#game-canvas", position={"x": 1050, "y": 620})`, which invokes isometric raycasting in `combat_skills.js:483`, assigning `player.destination`. The render loop updates `(player.wx, player.wy)`. The probe computes Euclidean distance `(dx*dx + dy*dy)**0.5` (measured `2.1255 > 0.05`), confirming authentic in-game movement. |
| **Modal Lifecycle Pause Test Verification** | `test_r2_modal_lifecycle` | **PASS (CLEAN)** | Playwright clicks `#btn-open-settings`, verifies `#modal-settings` display, asserts `window.isGamePaused === true` and `#overlay-pause` visibility, presses `Escape`, and verifies `#modal-settings` closure and `window.isGamePaused === false`. This directly verifies the PoE2 pause game architecture. |

### Phase 2: Runtime Behavioral Verification (Dynamic)

| Runtime Step | Command Executed | Result | Verbatim Output / Evidence |
| :--- | :--- | :---: | :--- |
| **Web Server Liveness** | `is_port_open("127.0.0.1", 8088)` | **PASS** | Active on port 8088 serving `client/webapp/index.html`. |
| **Automated Playwright QA Suite** | `python tools/qa/run_browser_qa_suite.py --strict` | **PASS** (Exit 0) | ```log<br>[*] R1 FPS: Avg=33.6, Min=3.8, p99=264.3ms<br>[*] R1 i-Frame Window: 0.10349999999999998s verified<br>[*] R1 Player Movement: Distance=2.1255, Verified=True<br>[*] R2 Modal Lifecycle: Pause/Unpause Verified=True<br>[*] R2 Zero Reloads: True<br>[*] R3 Chunk Cache VRAM: 16 MB <= 16.5 MB<br>[*] Total Errors: 19, Crashes: 0<br>``` |
| **Process Integrity** | Headless Chromium / Edge process | **PASS** | Genuine browser instance launched, headless mode, 0 crashes, 0 page faults. |
| **Visual Artifact Freshness** | 10 live PNG screenshots in `docs/qa/reports/telemetry/` | **PASS** | All 10 screenshots generated and verified: `r1_combat_iframe.png`, `r1_player_movement.png`, `r2_desktop_widescreen.png`, `r2_mobile_landscape.png`, `r2_mobile_portrait.png`, `r2_modal_settings_open.png`, `r2_modal_settings_closed.png`, `r3_biome_traversal.png`, `r3_target_dummy.png`, `r3_vfx_overload.png`. |

### Phase 3: Code and Documentation Hygiene Verification

| Hygiene Gate | Command Executed | Standard / Cap | Result | Details |
| :--- | :--- | :--- | :---: | :--- |
| **Code & Doc Hygiene** | `python tools/lint/check_code_and_doc_hygiene.py --strict` | Hard Cap: Code <= 500 lines, Docs <= 600 lines | **PASS** (Exit 0) | 0 Hard Cap violations across entire repository. `run_browser_qa_suite.py` measures 335 lines (<= 350 Soft Cap) with 0 functions > 50 lines. |
| **i18n Hygiene & Parity** | `python tools/lint/check_i18n_hygiene.py --strict` | Rules 1, 2, 3: Zero hardcoded VI strings, 9-language parity, no dangling keys | **PASS** (Exit 0) | 0 violations. 100% compliant across all scanned UI modules. |
| **Documentation Line Limits** | Inspection of `docs/qa/reports/` | Docs Soft Cap <= 400 lines | **PASS** | All 7 bug reports measure 99–127 lines. `QA_EXECUTIVE_SUMMARY.md` measures 129 lines. |

---

### Phase 4: Unit Test Suite & Regression Verification

| Test Target | Command Executed | Result | Details |
| :--- | :--- | :---: | :--- |
| **Relevant Unit Tests** | `pytest tests/unit/test_dodge_and_evasion_iframe.py tests/unit/test_target_dummy_and_telemetry.py tests/unit/test_hud_orbs_and_skill_bar.py tests/unit/test_i18n_event_bus.py` | **PASS** (Exit 0) | 62 passed in 0.67s. Zero regressions across evasion i-frames, target dummy telemetry, skill bar slots, and i18n event bus. |
