Preview completion never applies draft criteria · case 01

Preview completion never applies draft criteria is violated by the widget projection.

Verified by executionVariant 1 · 10 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The committed-preserve decision uses `d['draft']` instead of the stipulated draft-preview projection.

VERIFIED REPAIR

Implement the declared committed-preserve projection: `d['committed']`.

Unsuccessful approach: The attempted correction `list(dict.fromkeys(d['committed']+d['draft']))` still violates the explicit contract fixtures.

Case contract

A filter preview is a noncommitting projection tagged with draft revision and scope. Invalid drafts cancel preview and stale replies do not replace the current estimate. This example checks: Preview completion never applies draft criteria.

Why this case matters

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

Verification & scope

Deterministic bounded UI-state model only; no browser, query engine, network, or production-standard conformance is claimed. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
