A lone trimmed sign is an incomplete draft rather than a general invalid value · case 01

A lone trimmed sign is an incomplete draft rather than a general invalid value is violated by the widget projection.

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

ROOT CAUSE

The incomplete-sign decision uses `not d['text'].strip().isdigit()` instead of the stipulated numeric-text-editor projection.

VERIFIED REPAIR

Implement the declared incomplete-sign projection: `d['text'].strip() in ('+','-')`.

Unsuccessful approach: The attempted correction `d['text'] in ('+','-')` still violates the explicit contract fixtures.

Case contract

This bounded numeric editor accepts ASCII signed integers with surrounding spaces, preserving incomplete drafts and disallowing exponent, decimal and non-ASCII forms. This example checks: A lone trimmed sign is an incomplete draft rather than a general invalid value.

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.
