Working Directory: c:\Projects\FreeExile\.agents\teamwork\challenger_final
Parent Conversation ID: 914399d4-059b-422e-a9e6-44e1005de38a

MANDATORY FIRST STEP:
Read:
- c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md (specifically ## 2026-10-02T02:12:28Z)
- c:\Projects\FreeExile\PROJECT.md
- c:\Projects\FreeExile\TEST_READY.md
- All worker handoffs:
  * c:\Projects\FreeExile\.agents\teamwork\worker_m1\handoff.md
  * c:\Projects\FreeExile\.agents\teamwork\worker_m2\handoff.md
  * c:\Projects\FreeExile\.agents\teamwork\worker_m3\handoff.md
  * c:\Projects\FreeExile\.agents\teamwork\worker_m4\handoff.md
  * c:\Projects\FreeExile\.agents\teamwork\worker_m5\handoff.md

YOUR MISSION:
Perform white-box adversarial analysis and coverage hardening across all implemented modules:
1. Inspect implementation source code:
   - `server/party/` (`party_types.py`, `party_scaling_calculator.py`, `party_service.py`)
   - `server/social/` (`social_types.py`, `social_repository.py`, `social_service.py`, `guild_roster_service.py`)
   - `server/world/` (`town_portal_types.py`, `town_portal_engine.py`, `teleport_service.py`)
   - `client/webapp/js/ui/` (`party_ui.js`, `social_ui.js`, `teleport_hud.js`, `town_portal_controller.js`)
2. Identify untested branches, corner cases, race conditions, or state desynchronizations:
   - Extreme party edge cases (rapid invites/declines, simultaneous leader leaves, boundary level gaps, division by zero).
   - Extreme social edge cases (rapid block/unblock, self-blocking, SQL injection in friend notes, whitespace notes).
   - Extreme teleport & portal edge cases (instant damage on frame 0, teleport to target who moves during cast, double quarantine triggers, 0-charge map re-entry attempts).
3. Author Tier 5 adversarial tests in `tests/e2e_social_party/test_tier5_adversarial_hardening.py` (ensure <= 350 lines).
4. Run test commands:
   - `pytest tests/e2e_social_party/test_tier5_adversarial_hardening.py -v`
   - `pytest tests/e2e_social_party/ -v`
   - `pytest tests/unit/test_party_scaling.py tests/unit/test_social_service.py tests/unit/test_teleport_and_portal.py tests/unit/test_client_ui_modules.py -q`
   - `python tools/lint/check_code_and_doc_hygiene.py --strict`
5. Report your findings and explicit verdict (APPROVE or REQUEST_CHANGES) in `c:\Projects\FreeExile\.agents\teamwork\challenger_final\handoff.md`.
Send message to parent when done.
