Ultimate Unified Memory System (Overkill Memory System)

VERSION 1.9.3 (SPEED-FIRST)

A comprehensive 6-tier memory architecture with neuroscience integration, WAL protocol, and full automation for OpenClaw agents.

Overview

The Ultimate Unified Memory System implements a biologically-inspired, speed-first memory hierarchy. It provides persistent, contextual memory across agent sessions with automatic importance weighting, emotional tagging, and value-based retention.

What It Does

Brain-Full Architecture: 6 brain regions (Hippocampus, Amygdala, VTA, Basal Ganglia, Insula, ACC)
Speed-First Architecture: Optimized for ~5ms average query time
Fast File Search: Uses fd + rg for 10x faster file tier searching
Knowledge Graph: Structured atomic facts with versioning
Self-Improving: Continuous learning from errors and corrections
Self-Reflection: Periodic self-assessment and performance review
Multi-Agent Support: Shared + private ChromaDB areas per agent
6-Tier Memory Architecture: From instant recall (HOT) to archival (COLD/GIT-NOTES)
Hybrid Neuroscience: Filter + Ranker approach for precision + speed
WAL (Write-Ahead Log) Protocol: Ensures no memory is ever lost
Neuroscience Integration: Hippocampus (importance), Amygdala (emotions), VTA (rewards/motivation)
Error Learning: Tracks and learns from user corrections
Spaced Repetition: FSRS-6 via Vestige for natural memory decay
Semantic Search: ChromaDB-powered vector storage for contextual retrieval
Cloud Backup: Supermemory integration for cross-device backup (NOT in query path)
Full Automation: Cron jobs for cross-session messages, platform posts, diary entries, and proactive memory maintenance

Speed Targets

Scenario	Time
Compiled query match	~0ms
Ultra-hot hit	~0.1ms
Hot cache hit	~1ms
Mem0 hit	~22ms
Full search	~55ms
Average	~5ms

Note: Supermemory is NOT in the query path - it's a background sync only (daily backup). This keeps queries fast (~5ms). Cloud access is only for backup/restore, not real-time queries.

## Memory System Checks

- [ ] Check cron-inbox for cross-session messages
- [ ] Check platform-posts for new activity
- [ ] Review recent daily notes for important context
- [ ] Update emotional state if significantly changed

Troubleshooting

Memory System Won't Initialize

bash

# Check directory permissions
ls -la ~/.openclaw/memory/

# Manually create directory
mkdir -p ~/.openclaw/memory

ChromaDB Connection Failed

bash

# Check if ChromaDB is running
curl http://localhost:8100/api/v1/heartbeat

# Or use keyword search fallback
python3 cli.py search "query" --method keyword

Ollama Embeddings Not Working

bash

# Check Ollama is running
curl http://localhost:11434/api/tags

# Verify embedding model
ollama list

Session State Not Persisting

bash

# Manually flush WAL buffer
python3 cli.py session end

# Check session file
cat ~/.openclaw/memory/SESSION-STATE.md

Memory Search Returns No Results

bash

# Rebuild search index
python3 cli.py analyze

# Try keyword fallback
python3 cli.py search "term" --method keyword

Git-Notes Sync Issues

bash

# Check git-notes directory
ls -la ~/.openclaw/memory/git-notes/

# Initialize git repo if needed
cd ~/.openclaw/memory/git-notes && git init

Benefit: O(1) wall-clock time instead of sequential O(n) tier traversal

Redis Hot Cache (L0)

Purpose: Ultra-fast L0 cache for frequently accessed memories
TTL: 5-15 minutes for hot data
Benefit: Sub-millisecond access for top results

Result Caching with TTL

Purpose: Cache search results to avoid redundant queries
TTL: 1-5 minutes depending on tier
Benefit: Dramatically reduces API calls and computation

Binary Search (Git-Notes)

How: Maintain sorted timestamp/index files
Benefit: Fast retrieval from large Git-Notes collections

Connection Pooling

Purpose: Reuse ChromaDB and Ollama connections
How: Persistent connection pools with health checks
Benefit: Eliminates connection overhead on each query

Bloom Filters

How: Probabilistic filter for memory presence
Benefit: Skip unnecessary tier searches when result is definitely not present

Pre-fetch Context

Purpose: Predictive memory loading based on context
How: Anticipate likely queries based on current session
Benefit: Results ready before user asks

Lazy Loading

Purpose: Load files only when needed
How: On-demand loading of large files
Benefit: Reduced memory footprint and faster initial response

Pre-computed Embeddings

Purpose: Cache embeddings for frequently queried content
How: Store embeddings alongside source data
Benefit: Skip embedding computation on cache hit
How: Store embeddings alongside source data
Benefit: Skip embedding computation on cache hit

Cache Strategy Details

Cache Hit: Return cached result immediately (sub-ms)
Cache Miss: Query next tier, cache result with TTL
Negative Cache: Optionally cache "not found" results (shorter TTL)
Cache Invalidation: On session end, new memory add, or manual trigger

⚠️ Prerequisites & Setup

Required Services (must be running)

ChromaDB on http://localhost:8100
Ollama on http://localhost:11434 with bge-m3 model

Optional Services (require API keys)

Mem0.ai account (for cloud fact extraction)
Supermemory.ai account (for cloud backup)
Redis (optional, falls back to in-memory)

Environment Setup

Copy .env.example to .env
Fill in optional API keys if using cloud features
Run python3 cli.py --help to get started

Manual Setup for Automation

The CLI provides commands but cron jobs are NOT auto-installed. To enable:

Add cron jobs manually via crontab -e
Example: 0 3 * * * python3 /path/to/cli.py cloud sync

⚠️ Important Notes

On-Import Side Effects

When Python imports cli.py, it may create memory directories under ~/.openclaw/memory/. This is intentional - the system needs these directories to function. To avoid this, run commands via subprocess rather than import.

No Auto-Installed Cron Jobs

The skill provides CLI commands for automation but does NOT auto-install cron jobs. You must manually add them if desired:

bash

# Add to crontab -e
0 3 * * * python3 /path/to/cli.py cloud sync

Cloud Features

Cloud features (Mem0, Supermemory) require API keys. Set in environment or .env file before use.

🔐 Security & Network Access

When Network Access Occurs

Variable	When Accessed	External Service
CHROMA_URL	If set	ChromaDB server
OLLAMA_URL	If set	Ollama server
MEM0_API_KEY	If set AND MEM0_USE_LOCAL=false	Mem0.ai API
SUPERMEMORY_API_KEY	If set	Supermemory.ai API
REDIS_URL	If set	Redis server

Default Behavior (No Network)

Without API keys, system runs fully offline
Uses local ChromaDB + local Ollama (if available)
All data stored locally in ~/.openclaw/memory/

Cloud Features

Only enabled when you:

Set MEM0_API_KEY and set MEM0_USE_LOCAL=false
Set SUPERMEMORY_API_KEY

These are opt-in only. Default = offline.
