# Cyclic Safeguards & Circuit Breakers

To guarantee rock-solid runtime stability across visual dialplans, **Asterisk 2** configures strict structural **Safety Filters**. The runtime evaluates active call paths to clamp infinite evaluation loops and clear deadlocked connections instantly.

## Runtime Traversal Loop Interception Map

The layout below traces how runtime token execution pointer steps pass across cyclic boundary safety logic:

## Architectural Circuit Breaker Rules

### 1. Hard Capped Execution Limits
To completely prevent graphic misconfigurations from dropping worker application kernels into infinite loop states, active call pointers enforce explicit linear evaluation bounds. If a single connected call attempts over 50 unpaused jumps inside a single sequence, evaluating logic execution drops out automatically.

### 2. Isolated Teardown Trapping
When safety boundaries clamp erroneous call paths, background controllers execute graceful application terminal disconnects (`Hangup`), clearing physical audio sessions without leaking server memory sockets.
