Case contract

A discrete range selector uses ordered option indices, preserves endpoint option identities across rerender, and renders unavailable selected options as unresolved. This example checks: Discrete range order follows option order and permits a single option.

Why this case matters

Filter-widget state and serialization must preserve user constraints while the view changes.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
contract fixture 0	`{"endpoint-payload": ["large", "small"], "full-domain": false, "lower-index": 2, "range-order": true, "unresolved-endpoints": [], "upper-index": 0}`	`{"endpoint-payload": ["large", "small"], "full-domain": false, "lower-index": 2, "range-order": false, "unresolved-endpoints": [], "upper-index": 0}`	Failed
