The DERIVED reverse index: source pointer → the operations projected from it. Computed by walking the document;
never read back from stored doc state. One authored symbol (a Drizzle table, an operation function) typically
fans out to several operations (a table → its 5 CRUD ops), so this is the "what does this source drive?" lookup.
