# DISPATCH — challenger_18_4

**Identity**: `challenger_18_4`
**Role**: Resilience & Error Cleanliness Re-Challenger
**Archetype**: `teamwork_preview_challenger`
**Working Directory**: `c:\Projects\FreeExile\.agents\teamwork\challenger_18_4\`
**Parent**: `orchestrator_18` (`75463099-5538-440a-8ff9-91c183526f7a`)

## Context & Objectives
You are an adversarial verifier empirically challenging the runtime stability, console cleanliness, primary attack audio execution, multi-resolution display scaling, and server security of `client/web_pc/` and `tools/serve_web_pc.py`.

## Reference Documents (MUST READ)
1. `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md` (header `## 2026-10-02T05:17:43Z`)
2. `c:\Projects\FreeExile\.agents\teamwork\challenger_18_2\handoff.md` (Original defect report)
3. `c:\Projects\FreeExile\.agents\teamwork\worker_iter4\handoff.md` (Applied remediation)

## Challenge Instructions
1. Write and run an empirical Python/Playwright test script in your working directory to challenge:
   - Primary attack (RMB and Key R): verify that invoking primary attack executes `sfxEngine.playWeaponSlash()` with strictly 0 unhandled `TypeError` exceptions.
   - All 10 key/mouse action triggers (`click`, `KeyQ`, `KeyW`, `KeyE`, `KeyR`, `Key1`, `Space`, `KeyC`, `KeyI`, `Escape`): verify that executing each sequentially produces strictly 0 page errors and 0 console errors.
   - Multi-resolution resilience across 16:9, 16:10, 21:9 Ultrawide, and 32:9 Super Ultrawide: verify 0 scrollbars.
   - Server path traversal rejection: test vectors `/../../../../Windows/win.ini`, `/../../.git/config`, `/%2e%2e/%2e%2e/Windows/win.ini`, `/C:/Windows/win.ini` to confirm that all return HTTP 404.
2. Run relevant tests:
   - `python .agents/teamwork/reviewer_18_2/test_do_primary.py`
   - `python .agents/teamwork/challenger_18_2/trace_errors.py`
   - `pytest tests/e2e/test_pc_desktop_client_e2e.py -k "traversal or zero_console" -v`
3. Deliver a comprehensive empirical report in `handoff.md` and render a clear verdict: `APPROVE` or `REJECT`. Send a concise notification message to parent.

Adversarially challenge runtime stability, console cleanliness, primary attack audio execution with sfxEngine.playWeaponSlash, 10 key/mouse action triggers without errors, multi-res display scaling, and server path traversal rejection (confirming 404 on all exploit vectors). Run empirical test scripts. Write your report with empirical evidence metrics and a clear verdict (APPROVE or REJECT) to c:\Projects\FreeExile\.agents\teamwork\challenger_18_4\handoff.md and notify parent with a concise message.
