Case contract

Text filters distinguish exact, prefix and contains modes; literal punctuation remains literal, and trimming and case policy are explicit editor options. This example checks: Serialized case policy uses positive case-sensitive polarity.

Why this case matters

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