# Strategy Pattern

Record: `arch:strategy-pattern`
Kind: pattern
Layer: [Design Patterns Core](https://banes-lab.com/records/layer/design-patterns-core.md)
Severity: recommended
Scope: algorithm, policy, behavior
Canonical: https://banes-lab.com/ontology#arch-strategy-pattern

## Repair

- Refactored by: Extract Strategy
- Detected by: conditional strategy selection with duplicated behavior
- Violated by: switch over behavior modes
- Measured by: conditional complexity
- Enforced by: complexity thresholds, [review](https://banes-lab.com/records/lex/review.md)
