# BRIEFING — 2026-10-03T08:36:00Z

## Mission
Independently review Protobuf compilation, WebSocket binary gateway bridge in server/gateway/ws_gateway_bridge.py, verify opcode framing, run all tests (tests/e2e_cocos/ and tests/unit/test_ws_protobuf_gateway.py), conduct adversarial critique for integrity and failure modes, deliver handoff.md with explicit verdict.

## 🔒 My Identity
- Archetype: teamwork_preview_reviewer
- Roles: reviewer, critic
- Working directory: c:\Projects\FreeExile\.agents\teamwork\reviewer_proto_qa
- Original parent: cecb05d6-3b1b-4c90-84e7-b52ac4e7697c
- Milestone: Protobuf Gateway & Cocos E2E Test Suite QA
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Report any failures as findings — do NOT fix them yourself
- Actively check for integrity violations (hardcoded test results, facade implementations, bypassed tasks, fabricated logs)
- Follow Handoff Protocol (Observation, Logic Chain, Caveats, Conclusion, Verification Method)

## Review Scope
- **Files to review**: `server/gateway/ws_gateway_bridge.py`, proto bundle (`client/cocos/assets/scripts/proto/`, `.proto` files, compiled artifacts)
- **Interface contracts**: `ORIGINAL_REQUEST.md`, `orchestrator_20/PROJECT.md`, `TEST_INFRA.md`, `TEST_READY.md`
- **Review criteria**: Correctness, Completeness, Quality, Security/Integrity, Adversarial Stress-Testing

## Review Checklist
- **Items reviewed**:
  - `server/gateway/ws_gateway_bridge.py`
  - `scripts/compile_protos.py`
  - `client/cocos/assets/scripts/proto/bundle.js` & `bundle.d.ts`
  - `client/cocos/assets/scripts/network/OpcodeRegistry.ts`
  - `client/cocos/assets/scripts/network/NetworkManager.ts`
  - `client/cocos/assets/scripts/core/KinematicsEngine.ts`
  - `tests/unit/test_ws_protobuf_gateway.py`
  - `tests/e2e_cocos/` (all 8 test files)
  - `tools/qa/run_cocos_human_journey.py`
- **Verdict**: REQUEST_CHANGES (Integrity violations + Opcode contract collisions + Kinematics bug)
- **Unverified claims**:
  - "0 Test Facades / Cheats (100% Genuine Contracts)" in TEST_READY.md: REFUTED (Multiple trivial tautology tests found in Tiers 2, 3, 4).
  - Opcode dispatch table interoperability: REFUTED (Critical opcode collision between bridge and Cocos client).

## Attack Surface
- **Hypotheses tested**:
  - Opcode parity between client and bridge: FAILED (Collisions between Move, Skill, Evasion, Zone, Chat).
  - Deadzone boundary consistency: FAILED (0.001 on bridge vs 0.05 on client/docs).
  - Real browser player journey organic execution: FAILED (State forced via JS DOM/state mutation).
  - Client velocity calculation: FAILED (Velocity always 0.0 in KinematicsEngine.ts).
- **Vulnerabilities found**:
  - Wire format ambiguity in opcode 0x0010 heuristic.
  - Trivial test assertions masking missing integration.
  - Memory leak in persistent player_states.
- **Untested angles**: Full CCU load on WebSocket bridge broadcast.

## Key Decisions Made
- Issued REQUEST_CHANGES verdict based on adversarial review and integrity violation criteria.
