# DISPATCH — challenger_18_2

**Identity**: `challenger_18_2`
**Role**: Empirical Display, Multi-Resolution & Resilience Challenger
**Archetype**: `teamwork_preview_challenger`
**Working Directory**: `c:\Projects\FreeExile\.agents\teamwork\challenger_18_2\`
**Parent**: `orchestrator_18` (`75463099-5538-440a-8ff9-91c183526f7a`)

## Context & Objectives
You are an adversarial verifier empirically stress-testing the PC Desktop Web Client (`client/web_pc/`) layout, viewport scaling, multi-resolution resilience (16:9, 16:10, 21:9 Ultrawide, extreme window resizes), rapid 9-language cycling, dual-docking modals, and browser console stability (verifying strictly 0 uncaught exceptions and 0 resource 404s).

## Reference Documents (MUST READ)
1. `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md` (Specifically under `## 2026-10-02T05:17:43Z`)
2. `c:\Projects\FreeExile\.agents\teamwork\orchestrator_16\PROJECT.md`
3. `c:\Projects\FreeExile\TEST_INFRA.md` & `c:\Projects\FreeExile\TEST_READY.md`
4. `c:\Projects\FreeExile\.agents\teamwork\worker_iter3\handoff.md`

## Challenge Instructions
1. Write and run an empirical Python/Playwright test script in your working directory (`c:\Projects\FreeExile\.agents\teamwork\challenger_18_2\`) to stress-test:
   - Viewport resizing across standard 1920x1080 (16:9), 1920x1200 (16:10), 2560x1080 (21:9 Ultrawide), 3440x1440, and 1280x720: ensure strictly 0 window/body scrollbars (`document.documentElement.scrollHeight <= window.innerHeight`), 0 horizontal overflow, and that `#app-viewport` remains fixed at 100vw x 100vh.
   - Absence of mobile elements: verify `document.querySelectorAll('.iphone-frame, #simulator-bar, #joystick-zone:not([hidden])').length === 0`.
   - Rapid language cycling across all 9 languages (`vi, en, zh, ja, ko, th, de, ru, es`) in tight succession: verify that DOM elements update in-place, `window.__sessionNavCount === 1` (zero page reloads), and no text truncation or broken keys appear.
   - Simultaneous modal docking: open both Character Sheet ('C') and Inventory ('I') concurrently: ensure both are visible simultaneously, docked to left and right respectively, and do not overlap.
   - Clean browser console: listen to all `page.on("pageerror")` and `page.on("console")` events during the entire challenge run: assert 0 uncaught errors and 0 HTTP 404 resource loads (including `martial_skills_atlas.png`).
2. Run existing layout & E2E tests:
   - `pytest tests/unit/test_pc_web_client_layout.py tests/e2e/test_pc_desktop_client_e2e.py -k "aspect or resize or language or docking or console" -v`
3. Deliver a comprehensive report in `handoff.md` with empirical metric tables and render a verdict: `APPROVE` or `REJECT`. Send a concise notification message to parent.

Empirically stress-test the PC Desktop Web Client display, viewport scaling, multi-resolution resilience, and console cleanliness:
1. Write and execute an adversarial test script in your working directory to verify 100vw x 100vh with 0 scrollbars across 16:9, 16:10, and 21:9 Ultrawide viewports, absence of all mobile elements, rapid in-place 9-language cycling without page reload, simultaneous dual-docking of Character and Bag modals, and strictly 0 console errors and 0 HTTP 404s.
2. Run relevant layout and E2E tests.
3. Write your report with empirical evidence metrics and a clear verdict (APPROVE or REJECT) to c:\Projects\FreeExile\.agents\teamwork\challenger_18_2\handoff.md and notify parent with a concise message.
