# CSC Score

> Understanding the Change Safety Confidence score

## Overview

The CSC score is calculated on every agent push (every 10 seconds by default). It evaluates four categories weighted to reflect deployment risk.

## Categories

### Policy Compliance (40 points)

Checks every pod and deployment for:

* Resource limits and requests defined
* Liveness and readiness probes configured
* Security context (non-root, read-only filesystem, capabilities dropped)
* Image pull policy and tag specificity (no `latest` tags)

### Runtime Signals (28 points)

Detects active problems:

* CrashLoopBackOff pods
* OOM kills
* High restart counts (>5)
* ImagePullBackOff
* Pending pods

### Historical Stability (17 points)

Tracks recent deployment changes:

* Image updates in the last 5 minutes
* Scale changes
* Rollouts in progress
* Rollback frequency

### Cluster Health (15 points)

Node-level health:

* Node Ready/NotReady status
* Memory and CPU pressure conditions
* Disk pressure
* Available capacity vs requested

## Custom Policies

Create custom scoring rules in **Policy Engine** to enforce your organization's standards. Custom policies add or subtract points from the CSC score when conditions match.

## Score History

Score history is persisted in PostgreSQL and survives backend restarts. View trends over days, weeks, or months in the Score History view. Export as CSV for compliance reporting.
