# Breakpoint Controller

> Managing interactive debugging state.

The Breakpoint Controller evaluates conditions during replay and manages the interactive execution state.

## Breakpoint Types

* **Static**: Specific contract addresses or function names.
* **Dynamic**: Budget thresholds (e.g., "break when CPU usage > 500k") or storage access patterns.

## State Snapshots

To support backward stepping without a full re-execution, the controller snapshots the execution context at every breakpoint.
