+# Workflow Data Model
+
+## Overview
+
+This document defines the complete data model for the workflow system using a **JSON-only architecture**. JSON task files are the single source of truth, with all documents generated on-demand as read-only views.
+
+## Core Data Architecture
+
+### Key Principle: JSON-Only Data Model
+**JSON files (.task/impl-*.json) are the only authoritative source of task state. All markdown documents are read-only generated views that never persist state.**
+
+- **Task State**: Stored exclusively in JSON files
+- **Documents**: Generated on-demand from JSON data
+- **No Synchronization**: Eliminates bidirectional sync complexity
+- **Performance**: Direct JSON access without parsing overhead
+
+## Task JSON Schema
+
+### Core Task Structure
+All task files use this simplified 8-field schema:
+
+```json
+{
+  "id": "impl-1",
+  "title": "Build authentication module",
+  "status": "pending",
+  "type": "feature", 
+  "agent": "code-developer",
+  
+  "context": {
+    "requirements": ["JWT authentication", "OAuth2 support"],
+    "scope": ["src/auth/*", "tests/auth/*"],
+    "acceptance": ["Module handles JWT tokens", "OAuth2 flow implemented"],
+    "inherited_from": "WFS-user-auth"
+  },
+  
+  "relations": {
+    "parent": null,
+    "subtasks": ["impl-1.1", "impl-1.2"],
+    "dependencies": ["impl-0"]
+  },
+  
+  "execution": {
+    "attempts": 0,
+    "last_attempt": null
+  },
+  
+  "meta": {
+    "created": "2025-09-05T10:30:00Z",
+    "updated": "2025-09-05T10:30:00Z"
+  }
+}
+```
+
+### Status Values
+- **pending**: Task created but not started
+- **active**: Task currently being worked on  
+- **completed**: Task successfully finished
+- **blocked**: Task cannot proceed due to dependencies
+- **container**: Parent task with subtasks (not directly executable)
+
+### Task Types
+- **feature**: New functionality implementation
+- **bugfix**: Fixing existing issues
+- **refactor**: Code improvement without functionality change
+- **test**: Test implementation or testing tasks
+- **docs**: Documentation creation or updates
+
+## Hierarchical Task System
+
+### Task Hierarchy Rules
+**Maximum Depth**: 3 levels (impl-N.M.P format)
+
+```
+impl-1              # Main task
+impl-1.1            # Subtask of impl-1
+impl-1.1.1          # Detailed subtask of impl-1.1
+impl-1.2            # Another subtask of impl-1
+impl-2              # Another main task
+```
+
+### Parent-Child Relationships
+```json
+// Parent task
+{
+  "id": "impl-1",
+  "title": "Build authentication module",
+  "status": "pending",
+  "relations": {
+    "parent": null,
+    "subtasks": ["impl-1.1", "impl-1.2"],
+    "dependencies": []
+  }
+}
+
+// Child task
+{
+  "id": "impl-1.1",
+  "title": "Design auth schema", 
+  "status": "pending",
+  "relations": {
+    "parent": "impl-1",
+    "subtasks": [],
+    "dependencies": []
+  }
+}
+```
+
+### Task Status Rules
+
+#### Container Task Rules
+- Parent tasks become "container" status when broken down
+- Cannot be directly executed (must execute subtasks)
+- Status derived from subtask completion
+
+#### Leaf Task Rules
+- Only leaf tasks can be executed directly
+- Status reflects actual execution state
+- Progress tracked at leaf level only
+
+## Context Management
+
+### Context Structure
+Context provides complete information for agent execution:
+
+- **requirements**: Specific functional requirements
+- **scope**: File patterns and modules affected  
+- **acceptance**: Success criteria and completion definition
+- **inherited_from**: Source workflow or parent task
+
+### Context Inheritance
+- **Workflow → Task**: Global requirements and constraints
+- **Parent → Subtask**: Refined scope and specific requirements
+- **Context Preservation**: All fields maintained for agent execution
+
+## Complexity Classification
+
+### Simple Workflows
+**Criteria**: Direct implementation tasks with clear scope
+- **Structure**: Single-level tasks (impl-N format)
+- **Task Files**: impl-*.json only
+- **Max Depth**: 1 level
+- **Task Count**: <5 tasks
+
+### Medium Workflows  
+**Criteria**: Feature implementation requiring task breakdown
+- **Structure**: Two-level hierarchy (impl-N.M format)
+- **Task Files**: Parent and child JSON files
+- **Max Depth**: 2 levels
+- **Task Count**: 5-15 tasks
+
+### Complex Workflows
+**Criteria**: System-wide changes requiring detailed decomposition
+- **Structure**: Three-level hierarchy (impl-N.M.P format)
+- **Task Files**: Multi-level JSON hierarchy
+- **Max Depth**: 3 levels (maximum allowed)
+- **Task Count**: >15 tasks
+
+## Agent Integration
+
+### Agent Assignment
+Based on task type and title keywords:
+- **Planning tasks** → planning-agent
+- **Implementation** → code-developer  
+- **Testing** → test-agent
+- **Documentation** → docs-agent
+- **Review** → review-agent
+
+### Execution Context
+Agents receive complete task JSON plus workflow context:
+```json
+{
+  "task": { /* complete task JSON */ },
+  "workflow": {
+    "session": "WFS-user-auth",
+    "phase": "IMPLEMENT"
+  }
+}
+```
+
+## File Organization
+
+### JSON Task Files
+**Location**: `.task/impl-[id].json`
+**Naming**: Follows hierarchical ID format
+**Content**: Complete task definition
+
+### Document Generation
+**On-Demand**: Documents generated from JSON when requested
+**Read-Only**: Documents never store state
+**Templates**: Standard templates for consistent output
+
+#### Generated Documents
+- `TODO_LIST.md`: Task progress view generated from JSON
+- `IMPL_PLAN.md`: Planning document with task references
+- Task summaries: Generated from completed task JSON
+
+## Data Operations
+
+### Task Creation
+```bash
+# Create new task JSON file
+echo '{"id":"impl-1","title":"New task",...}' > .task/impl-1.json
+```
+
+### Task Updates
+```bash
+# Update task status directly in JSON
+jq '.status = "active"' .task/impl-1.json > temp && mv temp .task/impl-1.json
+```
+
+### Document Generation
+```bash
+# Generate TODO_LIST.md from current JSON state
+generate_todo_list_from_json .task/
+```
+
+## Validation Rules
+
+### Task Integrity
+1. **ID Uniqueness**: All task IDs must be unique
+2. **Hierarchical Format**: Must follow impl-N[.M[.P]] pattern
+3. **Parent References**: All parent IDs must exist as JSON files
+4. **Depth Limits**: Maximum 3 levels deep
+5. **Status Consistency**: Status values from defined enumeration
+6. **Required Fields**: All 8 core fields must be present
+
+### Relationship Validation  
+- Parent-child relationships must be bidirectional
+- Dependencies must reference existing tasks
+- Container tasks cannot be completed until all subtasks complete
+- No circular dependencies allowed
+
+## Error Handling
+
+### Common Scenarios
+1. **Missing JSON File**: Indicates broken reference - must repair
+2. **Invalid Status**: Update to valid status value
+3. **Broken Hierarchy**: Reconstruct parent-child relationships  
+4. **Orphaned Task**: Reassign to proper parent or workflow
+
+### Recovery Strategy
+- **JSON Authoritative**: Task JSON files are source of truth
+- **Validation Warnings**: For non-critical inconsistencies
+- **Manual Resolution**: For complex relationship conflicts
+- **Document Regeneration**: Recreate documents from JSON when corrupted
+
+## Performance Benefits
+
+### JSON-Only Architecture
+- **Direct Access**: No document parsing overhead
+- **Atomic Updates**: Single file operations
+- **No Sync Conflicts**: Eliminates coordination complexity
+- **Fast Queries**: Direct JSON traversal
+- **Scalability**: Handles hundreds of tasks efficiently
+
+### On-Demand Generation
+- **Memory Efficient**: Documents created only when needed
+- **Always Fresh**: Generated views reflect current state
+- **No Stale Data**: Eliminates sync lag issues
+

+
+**System ensures**: Consistent task management using simplified JSON-only data model with complete context preservation for agent execution and on-demand document generation for human readability
