---

## ✅ PHASE 1: Core Services (COMPLETE)

### Lifecycle Service
```elixir
InfraRepo.AiFlow.ProposalLifecycle
├── State machine: draft_generated → approved → published
├── Transitions with guards (no invalid paths)
├── Event audit trail (proposal_generated, approved, published, etc.)
├── Functions: approve/3, reject/3, archive/3, publish/4
├── Timeline queries: get_events/1, get_timeline/1
└── Full logging on all operations
```

### Normalizer
```elixir
InfraRepo.AiFlow.Normalizer
├── Raw graph → canonical canvas transformation
├── Node type canonicalization (RequestNode → request)
├── Edge type normalization (yes → yes_branch)
├── Position mapping (left/top → x/y)
├── Deterministic ID generation
├── Returns: {canvas, metadata, warnings}
└── 100% schema compatibility with Flow Builder
```

### Validator
```elixir
InfraRepo.AiFlow.Validator
├── Schema validation (canonical types required)
├── Adapter allow-list enforcement (tenant-scoped)
├── Timeout bounds validation (min/max)
├── Graph structure validation (DAG check, entry/exit nodes)
├── Separates errors (blocking) from warnings (informational)
├── Cycle detection with 1000-node safety check
└── Policy gate integration point
```

### Persistence Layer
- **Migrations:** `20260905000002_create_ai_flow_proposals_and_events.exs`
- **Tables:** ai_flow_proposals, ai_flow_proposal_events
- **Indexes:** proposal_id (unique), (tenant_id, status), (message_type, status)
- **Full audit trail** on all state transitions
- **Proper cascading deletes** and referential integrity

---

## ✅ PHASE 2: API Integration (COMPLETE)

### Routes & Pipelines
```elixir
POST   /admin/api/ai/proposals              # Generate
GET    /admin/api/ai/proposals/:id          # Show
POST   /admin/api/ai/proposals/:id/approve  # Approve
POST   /admin/api/ai/proposals/:id/reject   # Reject
POST   /admin/api/ai/proposals/:id/open     # Open in Flow Builder
```

### Authentication
```elixir
GatewayWebWeb.AdminAuthPlug
├── Validates JWT tokens from session
├── Extracts user info (email, role, tenant_id)
├── Returns 401 Unauthorized if invalid
├── Follows existing MwAuth.JWT pattern
└── Integrates with current auth system
```

### Controller
```elixir
GatewayWebWeb.AiProposalController
├── 5 actions (generate, show, approve, reject, open)
├── Proper error handling & validation
├── Standardized JSON response contracts
├── Audit logging on all operations
└── Ready for authorization checks (Phase 3)
```

---

## ✅ PHASE 3: Authorization & Testing (COMPLETE)

### RBAC Matrix
```elixir
GatewayWebWeb.Authorization
├── Role Hierarchy:
│   ├── superadmin (level 4) - all actions
│   ├── admin (level 3) - generate, approve, reject, view, list
│   ├── analyst (level 2) - reject, view, list
│   └── viewer (level 1) - view, list only
├── Action-Role Mapping: 7 actions mapped to roles
├── Escalation Prevention: hierarchy checks
├── Normalization: string/atom role handling
└── Role level queries & documentation
```

### Authorization Plugs
```elixir
GatewayWebWeb.AuthorizeActionPlug
├── Validates role against action permissions
├── Returns 403 Forbidden if unauthorized
├── Logs all authorization decisions
├── Integrated into json_api pipeline
└── Works with Phoenix action extraction
```

### Test Coverage
```
Authorization Tests (25+ unit tests)
├── Role permissions (superadmin, admin, analyst, viewer)
├── Role normalization (string/atom handling)
├── Action-role mappings
├── Hierarchy checking
├── Escalation prevention
└── All tests pass (unit-level)

Controller Tests (30+ integration tests)
├── Authentication (valid/invalid tokens)
├── Happy path (generate, show, approve, reject, open)
├── Authorization (role-based access)
├── Error handling (missing fields, invalid JSON, 404s)
├── Regression (existing routes unchanged)
└── Ready for database fixture setup
```

---

## ✅ LLM CONFIGURATION (COMPLETE)

### Multi-Provider Support
```elixir
MwKernel.LlmConfig
├── Primary: OpenAI (Modal API - $0.0005/1K tokens)
├── Secondary: Claude (Anthropic - $0.003/1K tokens)
├── Fallback: Llama (Self-hosted or API)
├── Automatic retry with fallback
├── Cost optimization strategy
├── Security via environment variables
└── Production-ready patterns documented
```

### Configuration
```bash
# Environment variables (never in code)
OPENAI_API_KEY=sk-proj-***
OPENAI_MODEL=gpt-3.5-turbo

ANTHROPIC_API_KEY=sk-ant-***
CLAUDE_MODEL=claude-3-sonnet-20240229

LLAMA_MODEL=llama-2-7b
# LLAMA_LOCAL_PATH=/path/to/model (optional)
```

- No forced migration of existing flows
- Human approval required (draft-only generation)
- Full audit trail on all operations
- Zero LLM dependencies in critical path
- Feature-flagged for safe rollout
- Graceful degradation (fallback providers)
