# M1.6 & M2 Landscape Analysis
2+
3+
## M1.6.2 - Performance Benchmarks
4+
5+
### Existing Infrastructure ✅
6+
- **Framework**: Criterion v0.5 (already in use)
7+
- **Benchmark Files**:
8+
- `crates/mimi-cli/benches/cli_benchmarks.rs` - Auth operations (token gen, validation, permissions)
9+
- `crates/mimi-cli/benches/auth_benchmarks.rs` - Identity lifecycle, role hierarchy, registry
10+
- **Performance Tracking**:
11+
- `crates/mimi-cli/src/ai/performance_tracker.rs` - PerformanceTracker with latency percentiles, throughput, adaptive timeouts
12+
- `crates/mimi-cli/src/ai/performance.rs` - PerformanceMetrics with sliding window (100 samples), p50/p95/p99
13+
- `crates/mimi-cli/tests/ai_performance_integration.rs` - Integration tests for monitoring
14+
15+
### Required for M1.6.2
16+
**New Benchmarks to Add**:
17+
1. Message bus latency (Zenoh publish/subscribe/request-reply)
18+
2. FlatBuffers serialization/deserialization
19+
3. Mimi state machine throughput
20+
4. Beatrice CLI startup time
21+
22+
**Pattern**: Extend Criterion benches in `/benches/` directory; integrate PerformanceTracker pattern into core modules
23+
24+

25+
26+
## M1.6.3 - Documentation
27+
28+
### Existing Documentation ✅
29+
- **Architecture Docs** (in `/docs/`):
30+
- `M1.2.1-FLATBUFFERS-SCHEMA.md` - FlatBuffers message definitions
31+
- `M1.2.2-MESSAGE-BUS-SELECTION.md` - Zenoh vs alternatives
32+
- `M1.2.3-ZENOH-CLIENT-LIBRARY.md` - Zenoh setup
33+
- `M1.4.2-CLI-IMPLEMENTATION.md` - CLI design
34+
- `M1.4.3-REPL-IMPLEMENTATION.md` - REPL design
35+
- `M1.5.1-AI-ADAPTER-INTERFACE.md` - Adapter API
36+
- `M1.5.2-GEMINI-ADAPTER.md` - Gemini adapter specifics
37+
- `M1.5.3-OLLAMA-ADAPTER.md` - Ollama adapter specifics
38+
- `M1.5.4-ADAPTER-REGISTRY.md` - Registry design
39+

40+
41+
- **Implementation Plans** (in `/docs/plans/`):
42+
- 20+ detailed implementation plans with code examples
43+
- Covers M1.2 through M1.5 phases
44+
45+
- **Main README**: Portuguese project overview (high-level)
46+
47+
### Required for M1.6.3
48+
**Documentation Gaps**:
49+
1. ✅ API documentation - mostly covered in phase docs
50+
2. ❌ Sequence diagrams - NOT YET (CLI → Bus → Mimi → Adapter, WebSocket flow, Auth flow)
51+
3. ❌ Architecture diagrams - NOT YET (system overview, component interaction)
52+
4. ❌ Quick-start guide - NOT YET (how to start Mimi, send first query)
53+
5. ❌ Troubleshooting guide - NOT YET (common errors, debugging)
54+
6. ✅ FlatBuffers schema doc - covered in M1.2.1
55+
56+
**Action**: Create 5 new doc files in `/docs/`:
57+
- `ARCHITECTURE-OVERVIEW.md` - System diagram + component descriptions
58+
- `SEQUENCE-DIAGRAMS.md` - CLI, WebSocket, Auth flows with ASCII diagrams
59+
- `QUICKSTART.md` - Installation, docker-compose up, first query
60+
- `API-REFERENCE.md` - Consolidated from M1.5 docs
61+
- `TROUBLESHOOTING.md` - Common issues and solutions
62+
63+

64+
65+
## M1.6.4 - Deployment Preparation
66+
67+
### Existing Infrastructure ✅
68+
- **Dockerfile**: Multi-stage build for Mimi core (Rust 1.75, Debian bookworm)
69+
- **docker-compose.yml**: Full stack (Zenoh, Neo4j, Redis, Mimi core)
70+
- Services: Zenoh (7447, 7448, 7449), Neo4j 5.15 (7474, 7687), Redis 7 (6379), Mimi core (8080)
71+
- Health checks configured for all services
72+
- Volumes for Neo4j data/logs, Redis data
73+
- Environment variables for Mimi core integration
74+
- **docker-compose.override.yml**: Local development overrides
75+
- **CI/CD**: GitHub Actions (from `.github/workflows/`)
76+
77+
### Required for M1.6.4
78+
**Deployment Tasks**:
79+
1. ✅ Docker image - Dockerfile already exists
80+
2. ✅ docker-compose - Full stack defined
81+
3. ❌ Deployment checklist - DOCUMENT procedures
82+
4. ❌ Monitoring dashboard - IF APPLICABLE (optional)
83+
5. ❌ Environment templates - `.env.production`, `.env.test`
84+
6. ❌ Troubleshooting for deployment - Network issues, service health
85+
86+
**Action**: Create:
87+
- `DEPLOYMENT.md` - Checklist, prerequisites, step-by-step deploy procedure
88+
- `.env.production.example` - Production environment template
89+
- `MONITORING.md` - Health check endpoints, debugging service health
90+
- `SCALING.md` - Scaling Zenoh, Neo4j, Redis for production
91+
