## STATE TRANSITIONS (EXHAUSTIVE - 50+ TRANSITIONS)

### Item State Transitions

**Transition 1: Create Item**
- From: None
- To: DRAFT
- Trigger: User creates item
- Actions: Create item, broadcast event, index for search, add to activity feed
- Validation: Title required, type required
- Error handling: Validation error, database error

**Transition 2: Activate Item**
- From: DRAFT
- To: ACTIVE
- Trigger: User activates item or agent claims work
- Actions: Update status, broadcast event, notify assignees, update progress
- Validation: Item must exist, user must have permission
- Error handling: Item not found, permission denied

**Transition 3: Archive Item**
- From: ACTIVE
- To: ARCHIVED
- Trigger: User archives item or deletes item
- Actions: Update status, broadcast event, notify linked items, generate undo token
- Validation: Item must exist, user must have permission
- Error handling: Item not found, permission denied

**Transition 4: Restore Item**
- From: ARCHIVED
- To: DRAFT (or previous status)
- Trigger: User restores item using undo token
- Actions: Update status, broadcast event, restore relationships
- Validation: Undo token must be valid, not expired
- Error handling: Invalid token, token expired

- Error: "Item title is required"
- Severity: ERROR
- Action: Reject state change

**Rule 2: Item Type Valid**
- Condition: `!['REQUIREMENT', 'DESIGN', 'IMPLEMENTATION', 'TEST', 'DEPLOYMENT', 'DOCUMENTATION', 'RESEARCH', 'SPIKE'].includes(item.type)`

- Severity: ERROR
- Action: Reject state change

**Rule 3: Item Status Valid**

- Error: "Item status must be valid"
- Severity: ERROR
- Action: Reject state change

**Rule 4: Item Priority Valid**
- Condition: `!['LOW', 'MEDIUM', 'HIGH', 'CRITICAL'].includes(item.priority)`
- Error: "Item priority must be valid"
- Severity: ERROR
- Action: Reject state change

- Condition: `item.estimatedEffort && (item.estimatedEffort < 1 || item.estimatedEffort > 100)`
- Error: "Item effort must be between 1 and 100"
- Severity: ERROR
- Action: Reject state change

**Rule 6: Item Due Date Future**
- Condition: `item.dueDate && item.dueDate <= new Date()`
- Error: "Item due date must be in the future"
- Severity: WARNING
- Action: Allow state change with warning

**Rule 7: Item Assignees Valid**
- Condition: `item.assignees && item.assignees.some(id => !isValidUUID(id))`
- Error: "Item assignees must be valid user IDs"
- Severity: ERROR
- Action: Reject state change

**Rule 8: Item Tags Count**
- Condition: `item.tags && item.tags.length > 20`
- Error: "Maximum 20 tags allowed"
- Severity: ERROR
- Action: Reject state change

**Rule 9: Item Metadata Count**
- Condition: `item.metadata && Object.keys(item.metadata).length > 50`
- Error: "Maximum 50 metadata pairs allowed"
- Severity: ERROR
- Action: Reject state change

**Rule 10: Link Type Valid**
- Condition: `!['DEPENDS_ON', 'BLOCKS', 'RELATES_TO', 'IMPLEMENTS', 'TESTS', 'DOCUMENTS', 'DUPLICATES', 'SUPERSEDES'].includes(link.type)`
- Error: "Link type must be valid"
- Severity: ERROR
- Action: Reject state change

This is just the beginning. Each state model should have 50+ properties, 30+ transitions, and 100+ validation rules.
