     *   **The Dot Convention**: When a schema requests `family: "target.schema"`, the compiler extracts the base type (e.g. `schema`) and looks up its Physical Table definition.
     *   **Multi-Table Branching**: If the Physical Table is a parent to other tables (e.g. `organization` has variations `["organization", "bot", "person"]`), the compiler generates a dynamic `CASE WHEN type = '...' THEN ...` query, expanding into sub-queries for each variation. To ensure safe resolution, the compiler dynamically evaluates correlation boundaries: it attempts standard Relational Edge discovery first. If no explicit relational edge exists (indicating pure Table Inheritance rather than a standard foreign-key graph relationship), it safely invokes a **Table Parity Fallback**. This generates an explicit ID correlation constraint (`AND inner.id = outer.id`), perfectly binding the structural variations back to the parent row to eliminate Cartesian products.
     *   **Single-Table Bypass**: If the Physical Table is a leaf node with only one variation (e.g. `person` has variations `["person"]`), the compiler cleanly bypasses `CASE` generation and compiles a simple `SELECT` across the base table, as all schema extensions (e.g. `light.person`, `full.person`) are guaranteed to reside in the exact same physical row.
+    *   **Polymorphic Relation Type Filtering**: When a relationship maps to a polymorphic target with variations, the Queryer compiles an `IN` clause containing all allowed table variations (e.g., `counterparty_type IN ('bot', 'organization', 'person')`) rather than matching the base type literal, ensuring all polymorphic types are loaded correctly.
