StaticApplyA resolved lookup constraint carrying its allowed values and their display text.
Protected StaticAssertStaticInThe rows sorted by match value with an ordinal comparison: a database's collation may order them differently (or not at all), and the ordinal order is the same on every provider.
StaticLoadReads the lookup entity's allowed values (every row matching the optional Filter), skipping rows with an empty match column, in a stable order (the list is hashed and rendered into the prompt).
the output's lookup constraint as ResolveConstraint resolved it
Protected StaticToOne view row as an allowed value; none when its match column is empty. row is a runtime-shaped simple row (see Load).
A lookup constraint's allowed values: loading them and attaching them to a resolved constraint.
