negative_results

Scope: Negative results criteria.
Audience: Contributors and reviewers.
Guarantees: Failure scenarios are explicit and tested.
Non-Goals: Success narratives.
Why: This doc exists to record its single responsibility for review.

Overview

This doc defines negative results scenarios.
Architecture components are defined in Architecture.
Read Metrics for measurement context.

Contracts

A cyclic pathway must fail validation.
A proposal that increases energy cost must worsen stability.
Degraded proteins must not recover.

Invariants

Negative results are enforced by tests.
Failures are structured and observable.
No hidden recovery is allowed.

Failure Modes

Silent success invalidates results.
Missing failures invalidate tests.
Undefined scenarios are rejected.

Extension Points

Scenario changes update Metrics.
Contract changes update Pathway Limits.
Documentation updates follow Triage.

Exit Criteria

This doc becomes obsolete when results are generated.
The replacement is Metrics.
Obsolete docs are removed.
