# AI-Agentic Implementation - Session Summary

**Date:** 2026-05-24  
**Completed Phases:** Phase 1 Core Services + Phase 2 API Integration  
**Commits:** 2 (feat/ai-agentic-phase1)

---

## ✅ COMPLETED

### Phase 1: Core Services (2830 lines)
1. **Persistence Layer**
   - ai_flow_proposals & ai_flow_proposal_events tables
   - Full schemas with validation

2. **Lifecycle Service** (`InfraRepo.AiFlow.ProposalLifecycle`)
   - State machine: draft_generated → approved → published
   - Event audit trail on every transition
   - Functions: approve, reject, archive, publish, timeline queries

3. **Normalizer** (`InfraRepo.AiFlow.Normalizer`)
   - Raw graph → canonical canvas transformation
   - Node/edge type canonicalization
   - Deterministic ID generation

4. **Validator** (`InfraRepo.AiFlow.Validator`)
   - Schema validation (canonical types)
   - Adapter allow-list enforcement
   - Timeout bounds validation
   - Graph structure validation (DAG check)
   - Error vs warning differentiation

5. **API Controller** (`GatewayWebWeb.AiProposalController`)
   - 5 core endpoints (generate, show, approve, reject, open)
   - Proper error handling and response formatting

### Phase 2: API Integration (6 additional files)
1. **Routes** (router.ex)
   - JSON API pipeline with session support
   - /admin/api/ai/proposals endpoint scope
   - Full CRUD route mapping

2. **Authentication** (`GatewayWebWeb.AdminAuthPlug`)
   - JWT token verification from session
   - User info extraction (email, role, tenant_id)
   - 401 Unauthorized response for invalid tokens
   - Follows existing MwAuth.JWT pattern

3. **Infrastructure**
   - Phase 2 implementation plan documented
   - Code cleanup (UUID generation fix)

## 🚀 Ready for Phase 3

### Phase 3: RBAC & Testing (3-4 days)
Remaining work on feat/ai-agentic-phase1 branch:

1. **RBAC Matrix Implementation**
   - Role hierarchy (superadmin > admin > analyst > viewer)
   - Action-to-role mapping
   - Request validation with role checks

2. **Integration Tests**
   - API contract tests (happy path + errors)
   - Authorization tests (role-based)
   - Regression tests for existing endpoints
   - Feature flag gate tests

3. **Error Handling**
   - Standardized error responses
   - Validation error formatting
   - Database error handling

4. **Documentation**
   - API documentation update
   - Test coverage report
   - Deployment checklist

## 📁 Branch Information

**Branch:** `feat/ai-agentic-phase1`  
**Commits:** 2  
- `bb943c3`: Phase 1 core services
- `7b9f134`: Phase 2 route & auth integration

**Ready to merge to:** `main` (after Phase 3 completion)

---

## 🎯 Next Immediate Tasks

1. Implement RBAC role checking in controller
2. Add role validation before each action
3. Write API contract tests (ExUnit)
4. Test authorization boundaries
5. Verify no regressions on existing flows

---

## 🔒 Safety Status

✅ All non-breaking guarantees maintained:
- No changes to Flow Builder runtime
- No forced migration of existing flows
- Human approval required (draft-only generation)
- Full audit trail
- Feature-flagged for safe rollout

---

## 📝 Test Status

Currently:
- ❌ No unit tests (Phase 3 task)
- ❌ No integration tests (Phase 3 task)
- ✅ Code compiles without errors
- ✅ Manual verification of auth flow
