Estimated Effort: 10 story points

User Story

As a cadastre manager
I want to efficiently manage cadastre assignments, document synchronization, and communication tracking with enhanced workflows
So that I can streamline cadastral processes, maintain synchronized documentation between sites and cadastres, and effectively track all communications and operations with cadastre offices

Context & Integration

Current System Integration Points:

Extends existing CadastreService (/Users/ayoub/projects/emtb/apps/api/src/cadastre/cadastre.service.ts)
Leverages existing Cadastre Prisma model with fields (nom, adresse, telephone, email, region)
Integrates with Site-Cadastre relationship (cadastreId optional foreign key)
Maintains compatibility with existing Site-Client-Reclamation-ApporteurAffaire relationships
Utilizes Site documentsManquantsCadastres field for document tracking
Integrates with Site Document Workflow from Story 1

Existing Functionality to Preserve:

All Cadastre CRUD operations (GET /cadastres, POST /cadastres, PATCH /cadastres/:id, DELETE /cadastres/:id)
Cadastre creation with required nom field and optional contact information
Site-Cadastre optional relationship through cadastreId
Existing cadastre inclusion in Site queries with relationship loading
Site cadastre assignment and unassignment capabilities

Acceptance Criteria

AC1: Enhanced Cadastre Assignment & Management Workflows

Given I am managing cadastre assignments
When I work with site-cadastre relationships
Then the system should:

Provide intelligent cadastre assignment based on site location and region matching
Support bulk cadastre assignment for multiple sites
Enable cadastre reassignment with full audit trail
Implement cadastre workload balancing across available cadastre offices
Track cadastre assignment history and reason codes
Validate cadastre capacity and availability before assignment
Generate cadastre assignment reports with performance metrics
Support cadastre hierarchy management (main office, sub-offices, regional divisions)

AC2: Cadastre Document Synchronization & Validation

Given sites with assigned cadastres
When managing cadastral documentation
Then the system should:

Synchronize document requirements between Site and Cadastre entities
Automatically update Site.documentsManquantsCadastres based on cadastre-specific requirements
Cross-reference cadastral documents with Site Document Workflow from Story 1
Implement document validation rules specific to each cadastre office
Support cadastre-specific document templates and formats
Track document submission status to cadastres (SUBMITTED, UNDER_REVIEW, APPROVED, REJECTED)
Enable real-time document status sync between site workflow and cadastre processing
Generate cadastre document compliance dashboards

AC3: Contact Management & Communication Tracking

Given cadastre entities with contact information
When managing communications with cadastre offices
Then the system should:

Enhance existing cadastre contact fields (nom, adresse, telephone, email, region) with structured contact management
Track communication history (calls, emails, meetings, document exchanges)
Implement communication templates for common cadastre interactions
Support multi-contact management per cadastre (primary, secondary, specialized contacts)
Record communication outcomes and follow-up requirements
Generate communication schedules and reminder systems
Track response times and communication effectiveness metrics
Support bulk communication operations for multiple cadastres

AC4: Cadastre Performance Monitoring & Analytics

Given ongoing cadastre operations
When evaluating cadastre integration effectiveness
Then the system should:

Monitor cadastre response times for document processing
Track document approval/rejection rates per cadastre
Generate cadastre performance scorecards with efficiency metrics
Implement SLA tracking for cadastre document processing times
Provide cadastre workload distribution analytics
Monitor communication effectiveness and response rates
Track cadastre office availability and capacity utilization
Generate monthly cadastre performance reports

AC5: Integration with Site Document Workflow (Story 1)

Given the Site Document Workflow system from Story 1
When managing cadastral processes
Then the system should:

Seamlessly integrate with site status progression (NOUVEAU → DEMANDE_DOCUMENTS_CADASTRAUX → DOCUMENTS_CADASTREAUX_RECUS)
Automatically trigger cadastre document requests when sites reach DEMANDE_DOCUMENTS_CADASTRAUX status
Update site status to DOCUMENTS_CADASTREAUX_RECUS when cadastre confirms document receipt
Sync Site.documentsManquantsCadastres field with cadastre-specific document requirements
Coordinate document validation between site workflow and cadastre processes
Support cadastre-initiated document updates that reflect in site status
Enable cadastre document approvals to trigger automatic site status progression

AC6: Cadastre Document Repository & Version Management

Given cadastral documents and templates
When managing document standards and versions
Then the system should:

Maintain cadastre-specific document templates and requirement catalogs
Support versioned document templates with change tracking
Enable cadastre administrators to update document requirements
Provide document template comparison and diff functionality
Track document template usage across sites and cadastres
Support regional document variation management
Implement document standard compliance checking
Generate document template usage reports

AC7: Audit Trail & Evolution Tracking for Cadastre Operations

Given all cadastre-related operations
When performing any cadastre management activity
Then the system should:

Maintain comprehensive audit logs for all cadastre operations (assignment, communication, document updates)
Track evolution of cadastre assignments with timestamped changes and reason codes
Record all communication events with full context and outcomes
Implement audit trail search and filtering capabilities
Support audit report generation for compliance and review purposes
Track user actions and system-generated changes separately
Maintain data integrity validation for all cadastre-related changes
Provide audit trail export functionality for external review

Technical Implementation Approach

    id SERIAL PRIMARY KEY,
    cadastre_id INTEGER REFERENCES cadastres(id),
    site_id INTEGER REFERENCES sites(id),
    communication_type VARCHAR(50), -- EMAIL, PHONE, MEETING, DOCUMENT
