-# AI Process Builder + Chat Orchestrator
-
-A complete implementation of tenant-scoped AI process automation where admins design LangGraph-compiled workflows via React Flow UI, and end-users execute them through a Deep Agent chat orchestrator with deterministic, audited execution.
-
-## Architecture Overview
-
-### Backend Components
-
-#### 1. **Deep Agent Orchestrator** ([deep-agent.orchestrator.ts](backend/src/ai-processes/deep-agent.orchestrator.ts))
-- Uses LangChain/OpenAI to intelligently select processes
-- Extracts structured inputs from natural language
-- Generates friendly confirmation messages
-- Three-step workflow: discover → select → extract → execute
-
-#### 2. **Graph Compiler** ([ai-processes.compiler.ts](backend/src/ai-processes/ai-processes.compiler.ts))
-- Validates ReactFlow JSON graphs (Start/End nodes, reachability, cycles)
-- Compiles to LangGraph-compatible state machines
-- Validates tool allowlist and JSON schemas (Ajv)
-- Persists compiled artifact for versioned execution
-
-#### 3. **Runtime Executor** ([ai-processes.runner.ts](backend/src/ai-processes/ai-processes.runner.ts))
-- Executes compiled graphs deterministically
-- Implements 4 node types: LLMDecisionNode, ToolNode, HumanInputNode, End
-- Handles conditional edges via jsonlogic
-- Emits real-time events for streaming updates
-
-#### 4. **Tool Registry** ([tools/tool-registry.ts](backend/src/ai-processes/tools/tool-registry.ts))
-- Tenant-scoped tool allowlist (database-backed via AiToolConfig)
-- Demo tools wrapping ObjectService (findAccount, createAccount, etc.)
-- Context injection (tenantId, userId, knex) for secure execution
-
-#### 5. **Orchestrator Service** ([ai-processes.orchestrator.service.ts](backend/src/ai-processes/ai-processes.orchestrator.service.ts))
-- Integrates Deep Agent for process selection
-- Falls back to standard AI assistant when no processes configured
-- Manages chat sessions and message history
-- Streams execution events via SSE
-
-### Frontend Components
-
-#### 1. **AIChatBar** ([components/AIChatBar.vue](frontend/components/AIChatBar.vue))
-- Updated to call `/ai-processes/chat/messages` endpoint
-- SSE event stream consumer for real-time updates
-- Displays process selection, node execution, tool calls
-- Handles NEED_INPUT events for human-in-the-loop
-
-#### 2. **Process Management UI** ([pages/ai-processes/](frontend/pages/ai-processes/))
-- List view: displays all processes with versions
-- Editor view: React Flow integration via iframe + postMessage
-- Test runner for quick validation
-
-#### 3. **React Flow Editor** ([ai-processes-editor/src/App.tsx](frontend/ai-processes-editor/src/App.tsx))
-- Node palette: Start, LLMDecisionNode, ToolNode, HumanInputNode, End
-- Visual graph designer with drag-drop
-- Auto-saves to parent window via postMessage
-- Loads existing graphs for editing
-
-### Data Models (Objection.js)

-## Demo Process: Register New Pet
-
-A complete workflow demonstrating conditional logic and tool orchestration:
-
-1. **Extract Info** (LLMDecisionNode)
-   - Parses user message for pet + owner details
-   - Outputs structured JSON with validation
-
-2. **Find/Create Account** (Conditional)
-   - Searches for existing account by name/email
-   - Creates new account if not found
-   - Merges results into state
-
-3. **Find/Create Contact** (Conditional)
-   - Searches for existing contact under account
-   - Creates new contact if not found
-
-4. **Create Pet** (ToolNode)
-   - Inserts pet record linked to contact
-   - Returns pet ID
-
-### Seed the Demo Process
-
-```bash
-cd backend
-npm run migrate:tenant -- <tenant-slug>
-npm run seed:demo-process -- <tenant-slug>
-```
-
-### Test the Demo Process
-
-1. Navigate to `/ai-processes` in your tenant subdomain
-2. Open "Register New Pet" process
-3. Click "Test Run" or use the chat bar:
-
-```
-User: "Register a dog named Max, breed Golden Retriever, age 3, 
-       owned by John Smith, email john@example.com"
-
-Agent: 🔄 Selected process: Register New Pet
-       I'll register Max (Golden Retriever, 3 years old) for John Smith.
-       
-       ⚙️ Executing step: Extract Info
-       ✓ Extracted pet details
-       
-       🔧 Using tool: findAccount
-       ℹ️ Account not found, creating new account
-       
-       🔧 Using tool: createAccount
-       ✓ Created account for John Smith
-       
-       🔧 Using tool: findContact
-       ℹ️ Contact not found, creating new contact
-       
-       🔧 Using tool: createContact
-       ✓ Created contact: John Smith
-       
-       🔧 Using tool: createPet
-       ✓ Created pet: Max (ID: pet_1234567890)
-       
-       ✅ Process completed successfully!
-```

-  | { type: 'final', data: { output: any } }
-  | { type: 'error', data: { error: string } }
-```
-
-## Security & Guardrails
-
-### 1. **Tenancy Isolation**
-- All queries filtered by `tenantId` (enforced in Objection models)
-- Tool context includes tenant scope
-- Database-per-tenant architecture (inherited from platform)
-
-### 2. **Tool Allowlist**
-- Two-level validation:
-  - Tenant-level: `AiToolConfig` table (enabled tools per tenant)
-  - Compile-time: validates toolName exists in registry
-- Runtime check before tool execution
-
-### 3. **Schema Validation**
-- LLMDecisionNode output validated against JSON Schema (Ajv)
-- HumanInputNode input validated before resume
-- Graph structure validated at compile time
-
-### 4. **Audit Trail**
-- Every node execution logged to `ai_audit_events`
-- Includes: tool calls, LLM decisions, state mutations, errors
-- Queryable for compliance dashboards
-
-### 5. **Versioning**
-- Immutable process versions (create-only)
-- Runs reference specific version number
-- Graph definition + compiled artifact stored together
-
-## Running the System
-
-### 1. **Run Migrations**
-
-```bash
-cd backend
-npm run migrate:tenant -- tenant1
-```
-
-### 2. **Seed Demo Data**
-
-```bash
-npm run seed:demo-process -- tenant1
-```
-
-### 3. **Start Backend**
-
-```bash
-npm run start:dev
-```
-
-### 4. **Build Editor (if needed)**
-
-```bash
-cd frontend/ai-processes-editor
-npm install
-npm run build
-```
-
-### 5. **Start Frontend**
-
-```bash
-cd frontend
-npm run dev
-```
-
-### 6. **Access UI**
-
-- Admin UI: `http://tenant1.localhost:3001/ai-processes`
-- Chat UI: Available in bottom drawer on any page (⌘K to toggle)
-
-## Extension Points
-
-### Adding New Node Types
-
-1. Define type in [ai-processes.types.ts](backend/src/ai-processes/ai-processes.types.ts)
-2. Add schema validation in [ai-processes.schemas.ts](backend/src/ai-processes/ai-processes.schemas.ts)
-3. Implement executor in [ai-processes.runner.ts](backend/src/ai-processes/ai-processes.runner.ts)
-4. Add UI component in React Flow editor
-
-### Adding New Tools
-
-1. Implement handler in [tools/demo-tools.ts](backend/src/ai-processes/tools/demo-tools.ts)
-2. Register in `demoTools` export
-3. Add to tenant allowlist via UI or seed script
-4. Document input/output schema
-
-### Custom LLM Decision Logic
-
-Override `llmDecision` callback in [ai-processes.service.ts](backend/src/ai-processes/ai-processes.service.ts):
-
-```typescript
-llmDecision: async (node, state) => {
-  const prompt = renderTemplate(node.data.promptTemplate, state);
-  const response = await callOpenAI(prompt, node.data.model);
-  return validateAgainstSchema(response, node.data.outputSchema);
-}
-```
-
-## Troubleshooting
-
-### Process not appearing in chat
-
-- Check: `npm run seed:demo-process` completed successfully
-- Verify: Process exists in database (`select * from ai_processes`)
-- Check: Tools enabled (`select * from ai_tool_configs`)
-
-### Graph validation errors
-
-- Ensure exactly one Start node
-- Ensure at least one End node
-- Check all edges reference valid node IDs
-- Verify tool names match registered tools
-
-### SSE stream not working
-
-- Check CORS settings for subdomain routing
-- Verify `sessionId` returned from initial message
-- Check browser console for connection errors
-- Fallback: use polling endpoint (TODO: implement)
-
-## Next Steps
-
-1. **Enhanced Input Extraction**: Use Deep Agent to extract required fields per process
-2. **Visual Schema Builder**: UI for JSON Schema creation (drag-drop fields)
-3. **Conditional Edge Builder**: Visual jsonlogic editor
-4. **Process Analytics**: Dashboard showing run success rates, avg duration
-5. **Human-in-Loop UI**: Dynamic form renderer for HumanInputNode
-6. **Process Marketplace**: Share processes across tenants (with permissions)
-7. **Python Microservice**: Optional Python runtime for native LangGraph support

DEBUG_INCOMING_CALL.md

-# Debugging Incoming Call Issue
-
-## Current Problem
-- Hear "Connecting to your call" message (TwiML is executing)
-- No ring on mobile after "Connecting" message
-- Click Accept button does nothing
-- Call never connects
-
-## Root Cause Hypothesis
-The Twilio Device SDK is likely **NOT receiving the incoming call event** from Twilio's Signaling Server. This could be because:
-
-1. **Identity Mismatch**: The Device's identity (from JWT token) doesn't match the `<Client>ID</Client>` in TwiML
-2. **Device Not Registered**: Device registration isn't completing before the call arrives
-3. **Twilio Signaling Issue**: Device isn't connected to Twilio Signaling Server
-
-## How to Debug
-
-### Step 1: Check Device Identity in Console
-When you open the softphone dialog, **open Browser DevTools Console (F12)**
-
-You should see logs like:
-```
-Token received, creating Device...
-Token identity: e6d45fa3-a108-4085-81e5-a8e05e85e6fb
-Token grants: {voice: {...}}
-Registering Twilio Device...
-✓ Twilio Device registered - ready to receive calls
-Device identity: e6d45fa3-a108-4085-81e5-a8e05e85e6fb
-Device state: ready
-```
-
-**Note the Device identity value** - e.g., "e6d45fa3-a108-4085-81e5-a8e05e85e6fb"
-
-### Step 2: Check Backend Logs
-When you make an inbound call, look for backend logs showing:
-
-```
-╔════════════════════════════════════════╗
-║ === INBOUND CALL RECEIVED ===
-╚════════════════════════════════════════╝
-...
-Client IDs to dial: e6d45fa3-a108-4085-81e5-a8e05e85e6fb
-First Client ID format check: "e6d45fa3-a108-4085-81e5-a8e05e85e6fb" (length: 36)
-```
-
-### Step 3: Compare Identities
-The Device identity from frontend console MUST MATCH the Client ID from backend logs.
-
-**If they match**: The issue is with Twilio Signaling or Device SDK configuration
-**If they don't match**: We found the bug - identity mismatch
-
-### Step 4: Monitor Incoming Event
-When you make the inbound call, keep watching the browser console for:
-
-```
-🔔 Twilio Device INCOMING event received: {...}
-```
-
-**If this appears**: The Device SDK IS receiving the call, so the Accept button issue is frontend
-**If this doesn't appear**: The Device SDK is NOT receiving the call, so it's an identity/registration issue
-
-## What Changed
-- Frontend now relies on **Twilio Device SDK `incoming` event** (not Socket.IO) for showing incoming call
-- Added comprehensive logging to Device initialization
-- Added logging to Accept button handler
-- Backend logs Device ID format for comparison
-
-## Next Steps
-
-1. Make an inbound call
-2. Check browser console for the 5 logs above
-3. Check backend logs for Client ID
-4. Look for "🔔 Twilio Device INCOMING event" in browser console
-5. Try clicking Accept and watch console for "📞 Accepting call" logs
-6. Report back with:
-   - Device identity from console
-   - Client ID from backend logs
-   - Whether "🔔 Twilio Device INCOMING event" appears
-   - Whether any accept logs appear
-
-## Important Files
-- Backend: `/backend/src/voice/voice.controller.ts` (lines 205-210 show Client ID logging)
-- Frontend: `/frontend/composables/useSoftphone.ts` (Device initialization and incoming handler)

+# Authorization System Implementation Summary
+
+## ✅ Implementation Complete
+
+A comprehensive polymorphic record sharing and authorization system has been implemented with CASL, Objection.js, and NestJS.
+
+## What Was Built
+
+### Backend (NestJS + Objection.js + CASL)
+
+#### 1. Database Layer
+- ✅ Migration for authorization tables (`20250128000001_add_authorization_system.js`)
+- ✅ Updated Prisma schema with new models
+- ✅ Objection.js models: `ObjectField`, `RoleRule`, `RecordShare`
+- ✅ Updated existing models with new relations
+
+#### 2. Authorization Core
+- ✅ `AbilityFactory` - Builds CASL abilities from 3 layers (global, role, share)
+- ✅ Query scoping utilities for SQL-level authorization
+- ✅ Guards and decorators (`AbilitiesGuard`, `@CheckAbility()`, `@CurrentUser()`)
+- ✅ Middleware for attaching abilities to requests
+
+#### 3. API Endpoints
+- ✅ **ShareController** - CRUD for record shares
+  - POST /shares - Create share
+  - GET /shares/record/:objectDefinitionId/:recordId - List shares
+  - GET /shares/granted - Shares granted by user
+  - GET /shares/received - Shares received by user
+  - PATCH /shares/:id - Update share
+  - DELETE /shares/:id - Revoke share
+
+- ✅ **RoleController** - Role management
+  - Standard CRUD for roles
+  - RoleRuleController for CASL rules
+
+- ✅ **ObjectAccessController** - Object-level permissions
+  - GET/PUT /setup/objects/:apiName/access
+  - POST /setup/objects/:apiName/fields/:fieldKey/permissions
+  - PUT /setup/objects/:apiName/field-permissions
+
+### Frontend (Nuxt 3 + Vue 3)
+
+#### 4. Object Management Enhancement
+- ✅ Added "Access & Permissions" tab to object setup page
+- ✅ `ObjectAccessSettings.vue` component:
+  - Configure access model (public/owner/mixed)
+  - Set public CRUD permissions
+  - Configure owner field
+  - Set field-level read/write permissions
+
+#### 5. Role Management
+- ✅ New page: `/setup/roles`
+- ✅ `RolePermissionsEditor.vue` component:
+  - Configure CRUD permissions per object
+  - Apply conditions (e.g., own records only)
+  - Visual permission matrix
+
+#### 6. Record Sharing
+- ✅ `RecordShareDialog.vue` component:
+  - List current shares
+  - Add new shares with permissions
+  - Field-level scoping
+  - Expiration dates
+  - Revoke shares
+
+## Key Features
+
+### 🌍 Global Object Policies
+- Public/private access models
+- Default CRUD permissions per object
+- Configurable owner field
+- Field-level default permissions
+
+### 👥 Role-Based Access
+- CASL rules stored in database
+- Per-object permissions
+- Condition-based rules (e.g., ownerId matching)
+- Multiple actions per rule
+
+### 🔗 Per-Record Sharing
+- Polymorphic design (works with any object type)
+- Grant read/update access to specific users
+- Optional field-level scoping
+- Expiration and revocation support
+- Track who granted each share
+
+### 🔒 SQL Query Scoping
+- Critical for list endpoints
+- Ensures users only see authorized records
+- Combines ownership + sharing logic
+- Works with public access flags
+

+```
+
+## Next Steps
+
+### 1. Run the Migration
+```bash
+cd backend
+npm run migrate:latest
+```
+
+### 2. Initialize Existing Objects
+Set default access models for existing object definitions:
+```sql
+UPDATE object_definitions 
+SET 
+  access_model = 'owner',
+  public_read = false,
+  public_create = false,
+  public_update = false,
+  public_delete = false,
+  owner_field = 'ownerId'
+WHERE access_model IS NULL;
+```
+
+### 3. Apply Query Scoping
+Update existing controllers to use query scoping:
+
+```typescript
+import { applyReadScope } from '@/auth/query-scope.util';
+
+// In your list endpoint
+async findAll(@CurrentUser() user: User) {
+  const objectDef = await ObjectDefinition.query(this.knex)
+    .findOne({ apiName: 'YourObject' });
+  
+  let query = YourModel.query(this.knex);
+  query = applyReadScope(query, user, objectDef, this.knex);
+  
+  return query;
+}
+```
+
+### 4. Add Route Protection
+Use guards on sensitive endpoints:
+
+```typescript
+@UseGuards(JwtAuthGuard, AbilitiesGuard)
+@CheckAbility({ action: 'update', subject: 'Post' })
+async update(@Body() data: any) {
+  // Only users with 'update' permission on 'Post' can access
+}
+```
+
+### 5. Frontend Integration
+Add sharing button to record detail pages:
+
+```vue
+<template>
+  <div>
+    <!-- Your record details -->
+    <Button @click="showShareDialog = true">
+      <Share class="w-4 h-4 mr-2" />
+      Share
+    </Button>
+    
+    <RecordShareDialog
+      :open="showShareDialog"
+      :object-definition-id="objectDefinition.id"
+      :record-id="record.id"
+      :fields="objectDefinition.fields"
+      @close="showShareDialog = false"
+    />
+  </div>
+</template>
+```
+
+## Testing Checklist
+
+- [ ] Run database migration successfully
+- [ ] Create a test role with permissions
+- [ ] Configure object access settings via UI
+- [ ] Share a record with another user
+- [ ] Verify shared record appears in grantee's list
+- [ ] Verify query scoping filters unauthorized records
+- [ ] Test field-level permissions
+- [ ] Test share expiration
+- [ ] Test share revocation
+- [ ] Test role-based access with conditions
+
+## Performance Considerations
+
+1. **Index Usage**: The migration creates proper indexes on foreign keys and commonly queried columns
+2. **Query Scoping**: Uses SQL EXISTS subqueries for efficient filtering
+3. **Ability Caching**: Consider caching abilities per request (already done via middleware)
+4. **Batch Loading**: When checking multiple records, batch the share lookups
+
+## Security Notes
+
+⚠️ **Important**: Always use SQL query scoping for list endpoints. Never fetch all records and filter in application code.
+
+✅ **Best Practices**:
+- Share creation requires ownership verification
+- Only grantors can update/revoke shares
+- Expired/revoked shares are excluded from queries
+- Field-level permissions are enforced on write operations
+
+## Documentation
+
+Full documentation available in:
+- [AUTHORIZATION_SYSTEM.md](./AUTHORIZATION_SYSTEM.md) - Comprehensive guide
+- Inline code comments in all new files
+- JSDoc comments on key functions
+
+## Support
+
+For questions or issues:
+1. Check the documentation in `docs/AUTHORIZATION_SYSTEM.md`
+2. Review example usage in the controllers
+3. Examine the test cases (when added)

-# Softphone AI Assistant - Complete Implementation
-
-## 🎉 Features Implemented
-
-### ✅ Real-time AI Call Assistant
-- **OpenAI Realtime API Integration** - Listens to live calls and provides suggestions
-- **Audio Streaming** - Twilio Media Streams fork audio to backend for AI processing
-- **Real-time Transcription** - Speech-to-text during calls
-- **Smart Suggestions** - AI analyzes conversation and advises the agent
-
-## 🔧 Architecture
-
-### Backend Flow
-```
-Inbound Call → TwiML (<Start><Stream> + <Dial>) 
-→ Media Stream WebSocket → OpenAI Realtime API 
-→ AI Processing → Socket.IO → Frontend
-```
-
-### Key Components
-
-1. **TwiML Structure** (`voice.controller.ts:226-234`)
-   - `<Start><Stream>` - Forks audio for AI processing
-   - `<Dial><Client>` - Connects call to agent's softphone
-
-2. **OpenAI Integration** (`voice.service.ts:431-519`)
-   - WebSocket connection to `wss://api.openai.com/v1/realtime?model=gpt-4o-realtime-preview-2024-10-01`
-   - Session config with custom instructions for agent assistance
-   - Handles transcripts and generates suggestions
-
-3. **AI Message Handler** (`voice.service.ts:609-707`)
-   - Processes OpenAI events (transcripts, suggestions, audio)
-   - Routes suggestions to frontend via Socket.IO
-   - Saves transcripts to database
-
-4. **Voice Gateway** (`voice.gateway.ts:272-289`)
-   - `notifyAiTranscript()` - Real-time transcript chunks
-   - `notifyAiSuggestion()` - AI suggestions to agent
-
-### Frontend Components
-
-1. **Softphone Dialog** (`SoftphoneDialog.vue:104-135`)
-   - AI Assistant section with badge showing suggestion count
-   - Color-coded suggestions (blue=response, green=action, purple=insight)
-   - Animated highlight for newest suggestion
-
-2. **Softphone Composable** (`useSoftphone.ts:515-535`)
-   - Socket.IO event handlers for `ai:suggestion` and `ai:transcript`
-   - Maintains history of last 10 suggestions
-   - Maintains history of last 50 transcript items
-
-## 📋 AI Prompt Configuration
-
-The AI is instructed to:
-- **Listen, not talk** - It advises the agent, not the caller
-- **Provide concise suggestions** - 1-2 sentences max
-- **Use formatted output**:
-  - `💡 Suggestion: [advice]`
-  - `⚠️ Alert: [important notice]`
-  - `📋 Action: [CRM action]`
-
-## 🎨 UI Features
-
-### Suggestion Types
-- **Response** (Blue) - Suggested replies or approaches
-- **Action** (Green) - Recommended CRM actions
-- **Insight** (Purple) - Important alerts or observations
-
-### Visual Feedback
-- Badge showing number of suggestions
-- Newest suggestion pulses for attention
-- Auto-scrolling suggestion list
-- Timestamp on each suggestion
-
-## 🔍 How to Monitor
-
-### 1. Backend Logs
-```bash
-# Watch for AI events
-docker logs -f neo-backend-1 | grep -E "AI|OpenAI|transcript|suggestion"
-```
-
-Key log markers:
-- `📝 Transcript chunk:` - Real-time speech detection
-- `✅ Final transcript:` - Complete transcript saved
-- `💡 AI Suggestion:` - AI-generated advice
-
-### 2. Database
-```sql
--- View call transcripts
-SELECT call_sid, ai_transcript, created_at 
-FROM calls 
-ORDER BY created_at DESC 
-LIMIT 5;
-```
-
-### 3. Frontend Console
-- Open browser DevTools Console
-- Watch for: "AI suggestion:", "AI transcript:"
-
-## 🚀 Testing
-
-1. **Make a test call** to your Twilio number
-2. **Accept the call** in the softphone dialog
-3. **Talk during the call** - Say something like "I need to schedule a follow-up"
-4. **Watch the UI** - AI suggestions appear in real-time
-5. **Check logs** - See transcription and suggestion generation
-
-## 📊 Current Status
-
-✅ **Working**:
-- Inbound calls ring softphone
-- Media stream forks audio to backend
-- OpenAI processes audio (1300+ packets/call)
-- AI generates suggestions
-- Suggestions appear in frontend
-- Transcripts saved to database
-
-## 🔧 Configuration
-
-### Required Environment Variables
-```env
-# OpenAI API Key (set in tenant integrations config)
-OPENAI_API_KEY=sk-...
-
-# Optional overrides
-OPENAI_MODEL=gpt-4o-realtime-preview-2024-10-01
-OPENAI_VOICE=alloy
-```
-
-### Tenant Configuration
-Set in Settings > Integrations:
-- OpenAI API Key
-- Model (optional)
-- Voice (optional)
-
-## 🎯 Next Steps (Optional Enhancements)
-
-1. **CRM Tool Execution** - Implement actual tool calls (search contacts, create tasks)
-2. **Audio Response** - Send OpenAI audio back to caller (two-way AI interaction)
-3. **Sentiment Analysis** - Track call sentiment in real-time
-4. **Call Summary** - Generate post-call summary automatically
-5. **Custom Prompts** - Allow agents to customize AI instructions per call type
-
-## 🐛 Troubleshooting
-
-### No suggestions appearing?
-1. Check OpenAI API key is configured
-2. Verify WebSocket connection logs show "OpenAI Realtime connected"
-3. Check frontend Socket.IO connection is established
-4. Verify user ID matches between backend and frontend
-
-### Transcripts not saving?
-1. Check tenant database connection
-2. Verify `calls` table has `ai_transcript` column
-3. Check logs for "Failed to update transcript" errors
-
-### OpenAI connection fails?
-1. Verify API key is valid
-2. Check model name is correct
-3. Review WebSocket close codes in logs
