# 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.

- **How**: Mem0 extracts facts from conversations automatically
- **Benefit**: Reduces context window usage while preserving key information

### Parallel Tier Query
- **Purpose**: Query all memory tiers simultaneously
- **How**: Async queries to Mem0, ChromaDB, Git-Notes, and file search
- **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)
- **Purpose**: O(log n) lookup in sorted memory index
- **How**: Maintain sorted timestamp/index files
- **Benefit**: Fast retrieval from large Git-Notes collections

## Cloud Architecture (v1.0.5)

### Priority Order
```
Mem0 (L1 Cache) → ChromaDB → Git-Notes → Supermemory (Backup)
```

| Tier | Service | Purpose | Latency | Cost |
|------|---------|---------|---------|------|
| L0 | Redis | Hot cache | <1ms | Low |
| L1 | Mem0 | Auto-extracted facts | <10ms | Medium |
| L2 | ChromaDB | Semantic vectors | <50ms | Low |
| L3 | Git-Notes | Knowledge graph | <20ms | Free |
| Backup | Supermemory | Offsite backup | Daily | Free |

### Cloud Services Integration

#### Mem0 (L1 Cache)
- **Purpose**: First-layer cache for 80% token reduction
- **How**: Auto-extracts facts from conversations
- **API**: `MEM0_API_KEY` environment variable
- **Benefit**: Reduces context window usage while preserving key information

#### ChromaDB (Vector Storage)
- **Purpose**: Semantic similarity search
- **Embeddings**: bge-m3 via Ollama
- **Connection**: Pooled connections for speed
- **Fallback**: Keyword search if unavailable

#### Git-Notes (Knowledge Graph)
- **Purpose**: Structured JSON storage
- **Lookup**: Binary search O(log n)
- **Sync**: Git-based versioning

#### Supermemory (Cloud Backup)
- **Purpose**: Daily backup only (not real-time sync)
- **Frequency**: Once per day
- **API**: `SUPERMEMORY_API_KEY` environment variable
- **Benefit**: Reduces API calls while maintaining offsite backup

### Environment Variables
```bash
# Required for cloud features
MEM0_API_KEY=your_mem0_key          # Auto-fact extraction
SUPERMEMORY_API_KEY=your_key       # Cloud backup

# Optional overrides
CHROMA_URL=http://localhost:8100   # ChromaDB server
OLLAMA_URL=http://localhost:11434   # Ollama server
EMBEDDING_MODEL=bge-m3              # Embedding model
```

### 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
1. Copy `.env.example` to `.env`
2. Fill in optional API keys if using cloud features
3. 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:
1. Set MEM0_API_KEY and set MEM0_USE_LOCAL=false
2. Set SUPERMEMORY_API_KEY

These are opt-in only. Default = offline.
