# Predictability

Record: `arch:predictability`
Kind: quality-attribute
Layer: [Computation Core](https://banes-lab.com/records/layer/computation-core.md)
Severity: recommended
Scope: API, module, runtime
Canonical: https://banes-lab.com/ontology#arch-predictability

## Repair

- Refactored by: Make Behavior Explicit, Add Contracts
- Detected by: nondeterministic tests, ambiguous APIs
- Violated by: surprising side effects, implicit ordering
- Measured by: flake/misuse rate
- Enforced by: [tests](https://banes-lab.com/records/lex/tests.md), [contracts](https://banes-lab.com/records/lex/contracts.md), linting
