# Isolation

Record: `arch:isolation`
Kind: constraint
Layer: [Atomic Boundary](https://banes-lab.com/records/layer/atomic-boundary.md)
Severity: contextual
Scope: database, transaction, concurrency
Canonical: https://banes-lab.com/ontology#arch-isolation

## Repair

- Refactored by: Add Locking, Set Isolation Level
- Detected by: concurrency tests, isolation anomalies
- Violated by: race-condition state corruption
- Measured by: anomaly rate, lock contention
- Enforced by: DB isolation, concurrency tests
