# Causality

Record: `arch:causality`
Kind: principle
Layer: [Causality Core](https://banes-lab.com/records/layer/causality-core.md)
Severity: contextual
Scope: event, workflow, distributed state
Canonical: https://banes-lab.com/ontology#arch-causality

## Repair

- Refactored by: Add Causation ID, Add Ordering Rules
- Detected by: missing causation/correlation metadata
- Violated by: processing effects without known cause/order
- Measured by: causal trace completeness
- Enforced by: event schema and workflow tests

## requires
