# decisive_experiment  

**Scope:** Decisive experiment design.  
**Audience:** Reviewers and contributors.  
**Guarantees:** Experiment is interpretable.  
**Non-Goals:** Full protocol.  
Why: This doc exists to record its single responsibility for review.  

## Overview  
This doc defines one decisive experiment.  
Architecture context lives in [architecture/architecture.md](../architecture/architecture.md).  
Claim context lives in [falsifiable_claim.md](falsifiable_claim.md).  

## Contracts  
Experiment compares recovery rate with and without regulator proposals.  
Metrics follow [architecture/metrics.md](../architecture/metrics.md).  
The experiment uses deterministic replay from [architecture/execution_model.md](../architecture/execution_model.md).  
Evidence uses [tests/regression/test_negative_results.py](https://github.com/bijux/agentic-proteins/blob/main/tests/regression/test_negative_results.py).  

## Invariants  
Experiment inputs remain fixed.  
Experiment aligns with [../governance/core.md](../governance/core.md).  
Evidence aligns with [tests/regression/test_negative_results.py](https://github.com/bijux/agentic-proteins/blob/main/tests/regression/test_negative_results.py).  

## Failure Modes  
Missing controls breaks interpretation.  
Drift in setup breaks [falsifiable_claim.md](falsifiable_claim.md).  
Missing evidence breaks [../meta/DOCS_STYLE.md](../meta/DOCS_STYLE.md).  

## Extension Points  
Experiment updates follow [../meta/DOCS_STYLE.md](../meta/DOCS_STYLE.md).  
Extensions align with [architecture/experimental.md](../architecture/experimental.md).  
Evidence updates align with [tests/unit/test_docs_contract.py](https://github.com/bijux/agentic-proteins/blob/main/tests/unit/test_docs_contract.py).  

## Exit Criteria  
This doc is obsolete when an experiment suite exists.  
The replacement is [architecture/metrics.md](../architecture/metrics.md).  
Obsolete docs are removed.
