Unsafe success invalidates only successful statuses · case 04

Unsafe success invalidates only successful statuses.

Member previewVariant 4 · 3 implementations · 4 checks per implementation

Case contract

Bounded offline decision model: unsafe success invalidates only successful statuses. Inputs are already validated protocol fields; the explicit fixtures define the supported policy, not a complete protocol implementation.

Why this case matters

This deterministic http caching model isolates the unsafe-success-invalidates-only-successful-statuses policy at a network component boundary.

One recorded failure
