# Big-Upfront Frozen Architecture

> A defect in which major architectural decisions are fixed before the forces they answer are known.

Record: `architecture:big-upfront-frozen-architecture`
Kind: anti-pattern
Layer: [Enforcement Core](https://banes-lab.com/records/layer/enforcement-core.md)
Severity: discouraged
Scope: domain_boundary

## Repair

- Refactored by: [minimum_viable_architecture](https://banes-lab.com/records/architecture/minimum-viable-architecture.md), [evolutionary_architecture](https://banes-lab.com/records/architecture/evolutionary-architecture.md), [fitness_functions](https://banes-lab.com/records/architecture/fitness-functions.md), decision_review
- Detected by: heavy_architecture_before_usage, ADR_without_evidence, future-proofing_without_feedback
- Violated by: Lock in major architectural decisions before validating domain forces, quality attributes, operational realities, and change vectors.
- Measured by: decisions recorded without evidence
- Enforced by: decision records that require evidence, periodic decision review
