Protected StaticFieldThe target field a constrained field-target output resolves against; undefined for any other output.
StaticResolveResolveFromFields, with each lookup's allowed rows loaded by loadRows (in parallel) and attached
(LookupConstraintValues.Apply). This is the map the runner renders and validates with.
StaticResolveEach output's constraint resolved against its target field (a field-target output with a constraint only; field
names compared case-insensitively): an enum's field value list and a lookup's entity and match field. No rows are
loaded, so a lookup has no AllowedValues yet. Synchronous: a preview can render this at once.
the pipeline's entity; undefined resolves every constraint from the spec alone
Output constraints resolved against the target entity's fields, and lookups' allowed rows attached.
