Canonical: https://banes-lab.com/ontology/schema#the-resolutions

Every tension edge in the canon is listed with its resolution, meaning the two records, the mechanism that settles it, the layer each side owns and the rule. An explicit resolution is one the canon states, and the rest are derived from the layers the two sides occupy, by the derivation described in [separate, trade, or mitigate](https://banes-lab.com/software-architecture/principles/separate-trade-or-mitigate.md) on the architecture page.

### Do Not Repeat Yourself (DRY) against Locality of Behavior

- Mechanism: mitigation
- Stated by the canon

Details

Scope of the first
[Do Not Repeat Yourself (DRY)](https://banes-lab.com/records/arch/duplicate-code.md) · Layer: [Structural Core](https://banes-lab.com/records/layer/structural-core.md)

Scope of the second
[Locality of Behavior](https://banes-lab.com/records/lex/locality-of-behavior.md) · Layer: [Structural Core](https://banes-lab.com/records/layer/structural-core.md)

Rule
Knowledge that means the same thing, such as a rule, a schema or a single source of truth, is centralized. Code that only looks alike stays local, because abstracting a coincidental similarity produces shared code with no shared meaning.

### Normalization against Query Performance

- Mechanism: scope-separation
- Stated by the canon

Details

Scope of the first
[Normalization](https://banes-lab.com/records/arch/normalization.md) · Layer: [Contracts Core](https://banes-lab.com/records/layer/contracts-core.md)

Scope of the second
[Query Performance](https://banes-lab.com/records/lex/query-performance.md) · Layer: [Performance Core](https://banes-lab.com/records/layer/performance-core.md)

Rule
The source of truth is normalized into one canonical store with no duplication. Derived read models, or projections, are denormalized for query performance, and the canonical store never is, so the two live in separate scopes: the system of record and the read projection.

### Normalization against Denormalized Read Models

- Mechanism: scope-separation
- Stated by the canon

Details

Scope of the first
[Normalization](https://banes-lab.com/records/arch/normalization.md) · Layer: [Contracts Core](https://banes-lab.com/records/layer/contracts-core.md)

Scope of the second
[Denormalized Read Models](https://banes-lab.com/records/lex/denormalized-read-models.md) · Layer: [Performance Core](https://banes-lab.com/records/layer/performance-core.md)

Rule
The canonical store is normalized, and only the read models rebuilt from it are denormalized. Normalization governs the write model and denormalization governs the read projection, so the two never compete over one store.

### Database Normalization against Read Performance

- Mechanism: scope-separation
- Stated by the canon

Details

Scope of the first

[Read Performance](https://banes-lab.com/records/lex/read-performance.md) · Layer: [Performance Core](https://banes-lab.com/records/layer/performance-core.md)

Rule
The canonical schema stays normalized. Read performance comes from derived, denormalized projections rebuilt from it, never from denormalizing the source of truth.
