filter synthesis: omit Field-Backed JSONB Bubbles from Composed Filter References — only Table-Backed boundaries have a synthesized .filter to proxy to; a dangling proxy reference breaks downstream code generators consuming the exported registry. Fixture pins a bubble-typed property: omitted from the filter, raw schemas promoted, no phantom .filter.
