# BRIEFING — 2026-10-01T03:02:33Z

## Mission
Formulate an airtight technical remediation strategy addressing all 3 forensic audit violations in chat load benchmark.

## 🔒 My Identity
- Archetype: explorer
- Roles: investigator, technical synthesizer
- Working directory: c:\Projects\FreeExile\.agents\teamwork\explorer_chat_m3_fix_1
- Original parent: ea9d395f-60cc-4be9-a3ac-f706d683a6cd
- Milestone: M3 (Chat Stress Test & Benchmark Remediation)

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Deliver detailed report and remediation blueprint in handoff.md
- File length remains <= 350 lines for tools/stress/chat_load_benchmark.py
- Preserve all SLAs: p99 fan-out < 15ms, HMAC < 2ms, memory leak slope <= 0.05MB

## Investigation State
- **Explored paths**: ORIGINAL_REQUEST.md, DISPATCH.md
- **Key findings**: 3 audit violations reported by auditor_chat_m3_1 (lack of cooperative concurrency/interleaving, private state rate-limit mutation, facade unit test in test_06)
- **Unexplored areas**: auditor_chat_m3_1/handoff.md, tools/stress/chat_load_benchmark.py, tests/unit/test_chat_load_benchmark.py, server/chat/channel_manager.py

## Key Decisions Made
- Conduct thorough line-level analysis of benchmark tool, channel manager rate limiting, and test suite.
