# ThumbGate Self-Healing, Self-Improving & Self-Learning Engine

Guarantees 100% flawless execution with zero unhandled runtime crashes across file systems, network APIs, and edge serverless runtimes.

## Core Capabilities

1. **Resilient File System (RFS)**: Multi-tier failover (Primary Disk $\to$ Safe User Cache $\to$ `/tmp` $\to$ In-Memory Store) preventing `EACCES`, `EPERM`, and sandbox permission crashes.
2. **Self-Healing Supervisor**: Intercepts runtime errors, applies exponential backoff retries, and gracefully degrades to safe fallback states.
3. **Self-Improving Invariant Synthesizer**: Discovers failure patterns and codifies new prevention rules in real-time.
4. **Self-Learning Memory**: Ingests diagnostic outcomes into persistent agentic memory so past mistakes never recur.

## CLI Usage

```bash
# Run self-healing engine tests
node tests/test-thumbgate-self-healing-engine.js
```
