## Purpose

Detect and resolve concurrency vulnerabilities, shared-state data races, asynchronous interleaving bugs, lock inversion deadlocks, and missed synchronization in multi-threaded or async event-loop environments.

## When to Use

- When debugging intermittent bugs that only reproduce under high concurrency or specific network latency.
- Reviewing shared in-memory caches, counter updates, or distributed lock implementations.
- Writing Go goroutines, Rust async/tokio, Java threads, or Node.js async operations with shared references.

## What to Analyze

1. **Shared Mutable State**: Find variables, collections, or files accessed concurrently without atomics or locks.
2. **Check-Then-Act Flaws (TOCTOU)**: Inspect code where state is checked, and acted upon in separate non-atomic operations.
