A complete row requires a known field, supported operator and appropriate operand · case 01

A complete row requires a known field, supported operator and appropriate operand is violated by the widget projection.

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

ROOT CAUSE

The row-complete decision uses `d['field'] in d['fields'] and d['value'] is not None` instead of the stipulated predicate-row-schema projection.

THE FAILURE

The row-complete decision uses `d['field'] in d['fields'] and d['value'] is not None` instead of the stipulated predicate-row-schema projection.

Unsuccessful approach: The attempted correction `d['op'] in d['supported'] and (d['op']=='missing' or d['value'] is not None)` still violates the explicit contract fixtures.

Case contract

A filter-builder row uses schema capability lists to determine available operators and reset incompatible operands when its field changes. This example checks: A complete row requires a known field, supported operator and appropriate operand.

Why this case matters

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

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 10 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

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.

Observations recorded using Python 3.12.14 at 2026-09-29T14:41:06.380259+00:00.
