Search normalization versus displayed autocomplete text: suggestion lookup sends case-sensitive padded display text · case 03

The lookup completion transition produces an incorrect observable state.

Case contract

This controlled ASCII picker normalizes lookup by stripping outer whitespace and lowercasing, while preserving exact user draft and canonical option labels for display and commit. Matching offsets apply to the normalized query only; a normalization-equivalent edit still advances the display epoch.

Why this case matters

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