Last visited: 2026-10-01T02:54:40Z
Status: Completed

- [x] Initialized BRIEFING.md and DISPATCH.md
- [x] Inspect implementation of `tools/stress/chat_load_benchmark.py` and `tests/unit/test_chat_load_benchmark.py`
- [x] Adversarial audit: Mathematical calculations
  - [x] Percentile formula (`calculate_percentiles`): Verified nearest-rank index bounding, 0-indexing safety, empty list handling.
  - [x] Memory tracking logic (`tracemalloc`): Verified `get_traced_memory()` start/end heap, conversion to MB, steady-state residual growth logic isolating post-warmup leak slope.
  - [x] Fan-out counting: Verified exact matching across 8 channels (3,250,250 deliveries per 1,000 messages across 26,002 subscriber handles).
- [x] Non-interference with 30Hz Zone Loop verified: Zero imports/coupling between `server/chat/` and `server/world/`.
- [x] Unit test suite passed: `tests/unit/test_chat_load_benchmark.py` (8/8 tests OK in 0.325s).
- [x] E2E test suite passed: `tests/e2e/test_chat_distributed_system_e2e.py` (24/24 tests OK in 0.456s).
- [x] 1M CCU stress benchmark tool execution (task-32) completed: All SLAs PASS (p99 fan-out 8.17ms < 15ms, HMAC p99 0.056ms < 2ms, residual growth 0.0025MB <= 0.05MB).
- [x] Hygiene check passed (`python tools/lint/check_code_and_doc_hygiene.py --strict`): 0 Hard Cap violations.
- [x] Compile adversarial & quality review report with verdict in `handoff.md`.
- [ ] Send message to orchestrator parent.
