FA-22271 / Autocomplete interactions / Open access

Free-text option creation: created option retains the temporary identifier after persistence · case 01

The resolve completion transition produces an incorrect observable state.

ROOT CAUSE

At create-option/resolve, the implementation evaluates `d['temporary']` instead of preserving the specified completion transition.

THE FAILURE

At create-option/resolve, the implementation evaluates `d['temporary']` instead of preserving the specified completion transition.

Unsuccessful approach: The attempted repair uses `d['persisted'] or d['temporary']`, which still violates a normal or boundary completion fixture.

Case contract

This picker may create a new option from trimmed draft only when creation is enabled, the draft is nonempty, no case-insensitive exact label exists, and no create transaction is pending. Synthetic create rows carry a distinct namespace and raw text is never mistaken for a persisted identifier.

Why this case matters

Autocomplete couples draft text, suggestion identity and asynchronous presentation; this bounded lifecycle model isolates one observable interaction defect.

HELD IN THE MEMBER ARCHIVE

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

This mechanism has 22 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

Stipulated deterministic widget transition model; inputs are validated snapshots. It does not model browser event dispatch, network transport, or linguistic standards. 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 2026-09-29T14:40:36.972081+00:00.
