Current Status: Completed Tier 5 adversarial tests, verified all test suites, preparing handoff.md

## Steps
- [x] Step 1: Record dispatch message and create BRIEFING.md
- [x] Step 2: Read prerequisite documents (ORIGINAL_REQUEST.md, PROJECT.md, TEST_READY.md, worker handoffs M1-M5)
- [x] Step 3: Inspect implementation source code for party, social, world (portals/teleport), and client UI
- [x] Step 4: Identify edge cases, race conditions, vulnerabilities, and write Tier 5 adversarial tests in `tests/e2e_social_party/test_tier5_adversarial_hardening.py` (326 lines <= 350)
- [x] Step 5: Execute test suite and hygiene checks:
  * `pytest tests/e2e_social_party/test_tier5_adversarial_hardening.py -v` (13 passed in 0.20s)
  * `pytest tests/e2e_social_party/ -v` (119 passed in 0.38s)
  * `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` (55 passed in 5.77s)
  * `python tools/lint/check_code_and_doc_hygiene.py --strict` (Clean exit code 0)
- [x] Step 6: Write handoff report and notify parent agent with verdict (APPROVE)
