# BRIEFING — 2026-10-01T00:45:00Z

## Mission
Mine and document all precise specifications from docs/architecture/CHAT_AND_SOCIAL_ARCHITECTURE_2026.md, proto/chat.proto, and ORIGINAL_REQUEST.md requirements R1 through R5 and Acceptance Criteria.

## 🔒 My Identity
- Archetype: spec_miner
- Roles: Specification Miner
- Working directory: c:\Projects\FreeExile\.agents\teamwork\spec_miner_chat_spec_1
- Original parent: 7020ed22-d577-4b8a-8fb7-a0bd4b2658d7
- Milestone: Chat & Social System Specification Mining

## 🔒 Key Constraints
- Authoritative specification discovery only — do NOT implement anything.
- Do NOT skip any feature, no matter how obscure.
- Prioritize authoritative sources over LLM prior knowledge.
- Format with standard tables: "## Features Discovered" and "## Edge Cases".
- Self-contained 5-component handoff report (Observation, Logic Chain, Caveats, Conclusion, Verification Method).
- Communicate results via send_message to caller parent.

## Task Summary
- **What to build**: Specification mining report for Chat and Social Systems (R1 to R5)
- **Success criteria**: Comprehensive discovery and documentation of channels, item linking snapshots, rate limits/spam suppression, 1M CCU Redis cluster pub/sub, zero-latency 30Hz game loop isolation, protobuf schemas, and edge cases.
- **Interface contracts**: proto/chat.proto, docs/architecture/CHAT_AND_SOCIAL_ARCHITECTURE_2026.md
- **Code layout**: .agents/teamwork/spec_miner_chat_spec_1/

## Key Decisions Made
- Fully probed all referenced docs, proto files, request requirements R1 to R5, test suites, and benchmarks.
- Documented 29 distinct features across 7 categories and 25 edge cases in handoff.md.
