Identity Persistence Layer

Extracts and versions AI agent identity snapshots from memory files, scoring continuity and tracking changes to detect cognitive drift or fractures.

Structured identity graph system for AI agents. Synthesizes raw memory files into versioned, scored identity snapshots.

What It Does

• Extracts core beliefs, personality traits, relationships, memories, cognitive patterns, and contradictions from agent markdown files
• Computes Continuity Score (0-1) using KL divergence on beliefs + MSE on traits
• Versions snapshots with diffs for drift detection
• Molting Protocol for model upgrades — freeze, verify, score

Requirements

• Gemini API key (for identity extraction)
• Agent workspace with MEMORY.md and/or SOUL.md files

Usage

python3 identity_manager.py              # Full cycle: extract + score + save
python3 identity_manager.py --score-only # Compare vs last snapshot
python3 identity_manager.py --freeze     # Pre-model-upgrade deep freeze

Architecture

• current_identity.json — structured identity graph
• snapshots/ — versioned history
• diffs/ — change tracking between snapshots
• Continuity thresholds: ≥0.90 stable, 0.75-0.89 drift, <0.75 fracture
