## Usage

```

```

## Maintenance Principles

1. **Incremental Updates**: Only append, never delete (use deprecated markers)
2. **Version Tracking**: Keep history for important changes
3. **Cross-validation**: Check for conflicts before updating
4. **Regular Organization**: Organize memory every 10 chapters

## Memory Retrieval Priority

When querying memory, use this order:
1. canon.md (highest priority, cannot be violated)
2. world_rules.md (rule level)
3. characters_evolution.md (character state)
4. foreshadowing.md (plot threads)

## Regular Maintenance Tasks

- Every 10 chapters: Organize canon, remove redundancy
- Each volume end: Restructure memory directory
- When conflict found: Immediate correction and recording
