# Chrono-Sovereign Settlement Engine (CSSE)

## Overview

CSSE enables settlement across asynchronous time domains, addressing interplanetary delays, multi-relativistic time offsets, and retroactive state integrity.

## Temporal Settlement Logic

### Pre-Commit Phase

```
t_precommit = HASH( predicted_state + sovereign_signature )
```

### Commit Phase

Executed when actual state matches predicted thresholds.

### Reconciliation Phase

Adjusts settlement value for:
- Delay cost
- FX drift
- Commodity shock delta

## Integration

CSSE extends Volume IX ISP temporal settlement (`isp-temporal.service.ts`) and integrates with:
- Quantum signature service
- FX engine for drift calculations
