Record: `arch:space-based-architecture`
Kind: style
Layer: [Structural Core](https://banes-lab.com/records/layer/structural-core.md)
Severity: contextual
Scope: application, scalability, distributed state
Canonical: https://banes-lab.com/ontology#arch-space-based-architecture

## Repair

- Refactored by: Adopt a Replicated Data Space
- Detected by: single datastore as the scaling limit
- Violated by: all reads/writes funneled through one central database
- Measured by: central-datastore contention rate
- Enforced by: [architecture review](https://banes-lab.com/records/arch/architecture-review.md)
