# DISPATCH — explorer_18_1

**Identity**: `explorer_18_1`
**Role**: Server Security & Test Rigor Remediation Explorer
**Archetype**: `teamwork_preview_explorer`
**Working Directory**: `c:\Projects\FreeExile\.agents\teamwork\explorer_18_1\`
**Parent**: `orchestrator_18` (`75463099-5538-440a-8ff9-91c183526f7a`)

## Context & Objectives
You are investigating the root cause and concrete fix strategy for the **FORENSIC AUDIT INTEGRITY VIOLATION** and test rigor defects discovered by `auditor_18_1`:
1. Critical Path Traversal / Arbitrary File Read in `tools/serve_web_pc.py` (lines 191–198) allowing `GET /../../../../Windows/win.ini` and `GET /../../.git/config` with HTTP 200.
2. Test Cheating & Error Masking in `tests/e2e/test_pc_desktop_client_e2e.py` (lines 147, 151) filtering out `"404"`, `"keys is not defined"`, and `"hudOrbs"`.

## Reference Documents (MUST READ IN FULL)
1. `c:\Projects\FreeExile\.agents\teamwork\auditor_18_1\handoff.md` (FULL FORENSIC AUDIT EVIDENCE REPORT)
2. `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md` (header `## 2026-10-02T05:17:43Z`)
3. `c:\Projects\FreeExile\.agents\teamwork\orchestrator_16\PROJECT.md`
4. `c:\Projects\FreeExile\tools\serve_web_pc.py`
5. `tests/e2e/test_pc_desktop_client_e2e.py`

## Instructions
1. Inspect `tools/serve_web_pc.py` around `_resolve_static_path` and `_handle_api_or_static`. Formulate a watertight fix ensuring paths cannot escape `PC_DIR` or `WEBAPP_DIR`, resolving paths and validating directory containment with Python's `Path.resolve()` / `.is_relative_to()`. Traversal attempts must strictly yield `None` (HTTP 404).
2. Inspect `tests/e2e/test_pc_desktop_client_e2e.py` around `test_tier1_zero_console_javascript_errors`. Formulate the exact edits to purge all error filters and assert `len(errors) == 0`.
3. Provide exact code diffs and step-by-step instructions for the Worker in your `handoff.md`. Do NOT implement code yourself. Report back to parent.

Investigate the root cause and formulate the exact remediation strategy for:
1. Critical Path Traversal in tools/serve_web_pc.py allowing arbitrary file read (e.g. win.ini, .git/config).
2. Test error masking in tests/e2e/test_pc_desktop_client_e2e.py lines 147 and 151 where '404', 'keys is not defined', and 'hudOrbs' errors were filtered out.
Produce exact code diffs and step-by-step instructions for the Worker in your handoff.md. Do NOT implement code yourself. Report back to parent.
