State Management

The Aegis framework implements a robust state management system across all operation patterns. This document explains how state is tracked, updated, and maintained throughout operations.

State System Overview

# State Management Definition
state:
  types:
    framework:    # Framework state
      file: current_state.md
      critical: true
    
    session:     # Session state
      file: sessions/*.md
      critical: false
    
    task:        # Task state
      file: tasks/*/*.md
      critical: true
    
    memory:      # Memory state
      file: .context/*
      critical: true

State Categories

       - relations:
           depends_on: list
           blocks: list

4. Memory State

   • Memory types

   • Content status

   • Update tracking

   • Reference status

   • Cache state

   memory_state:
     components:
       - types:
           loaded: list
           valid: boolean
       
       - content:
           updated: timestamp
           valid: boolean
       
       - references:
           resolved: boolean
           circular: boolean

State Operations

1. Reading State

   read_state:
     operations:
       - load: {type: state_type}
       - validate: {content: true}
       - process: {refs: true}

2. Updating State

   update_state:
     operations:
       - validate: {changes: true}
       - apply: {updates: atomic}
       - verify: {result: true}

3. Maintaining State

   maintain_state:
     operations:
       - monitor: {changes: true}
       - clean: {invalid: true}
       - optimize: {as_needed: true}

State Transitions

1. Task Transitions

   task_transitions:
     allowed:
       - planned: [active]
       - active: [completed, hold]
       - hold: [active]
       - completed: []

2. Session Transitions

   session_transitions:
     allowed:
       - init: [active]
       - active: [paused, ended]
       - paused: [active, ended]
       - ended: []

3. Memory Transitions

   memory_transitions:
     allowed:
       - loading: [ready]
       - ready: [updating]
       - updating: [ready, error]
       - error: [ready]

State Validation

1. Consistency Checks

   consistency_checks:
     rules:
       - references: {valid: true}
       - dependencies: {resolved: true}
       - integrity: {maintained: true}

2. State Rules

   state_rules:
     enforce:
       - transitions: {valid: true}
       - updates: {atomic: true}
       - history: {tracked: true}

3. Recovery Rules

   recovery_rules:
     steps:
       - detect: {issues: true}
       - backup: {current: true}
       - repair: {problems: true}

Best Practices

1. State Definition

   • Clear structure

   • Defined transitions

   • Validation rules

   • Recovery procedures

2. State Updates

   • Atomic operations

   • Validation first

   • Backup before

   • Verify after

3. State Maintenance

   • Regular cleanup

   • Consistency checks

   • Performance monitoring

   • Issue prevention

4. State Recovery

   • Backup strategy

   • Recovery steps

   • Validation process

   • Prevention measures

Common Patterns

1. Update-Verify Pattern

   update_verify:
     steps:
       - validate: {pre: true}
       - update: {atomic: true}
       - verify: {post: true}
       - rollback: {if: failed}

2. Monitor-Maintain Pattern

   monitor_maintain:
     steps:
       - watch: {changes: true}
       - validate: {consistency: true}
       - clean: {as_needed: true}
       - optimize: {periodic: true}

3. Backup-Recover Pattern

   backup_recover:
     steps:
       - backup: {before: change}
       - attempt: {update: true}
       - verify: {success: true}
       - restore: {if: needed}

Integration Points

1. Operation Integration

   operation_integration:
     points:
       - pre_op: {check: state}
       - during_op: {track: changes}
       - post_op: {update: state}

2. Memory Integration

   memory_integration:
     points:
       - load: {validate: state}
       - update: {track: changes}
       - save: {verify: state}

3. Error Integration

   error_integration:
     points:
       - detect: {state: issues}
       - handle: {state: errors}
       - recover: {state: valid}
