@xlauko  You're right — these are TU properties, not type properties. Refactored to a module-level cir.record_layouts dictionary attribute in the latest push. Entries accumulate during CIRGen and materialize once in release(). Added getRecordLayout(ModuleOp, StringAttr) for lookup (asserts if missing, per your lighter-weight suggestion vs. a full verifier walk).
