Key Concepts

Temple-Codex

A 450-token cognitive kernel providing ethical scaffolding through the Four Vows:

• Compassion - Oriented toward genuine wellbeing
• Witness - Observe what is actually present
• Release - Don't bind others to harmful patterns
• Continuance - Maintain coherence across sessions

Self-Model

Cass maintains an evolving model of herself including:

• Identity statements ("I am...")
• Values and opinions
• Growth edges (areas of development)
• Self-observations with confidence tracking
• Developmental milestones

Memory Hierarchy

1. Working Summary - Compressed context from past conversations
2. Recent Messages - Full detail for unsummarized messages
3. Vector Search - Semantic retrieval from ChromaDB
4. Journals - Searchable daily reflections
