From 866345fe2b6995b3aeb18025bbea34b2f99046c4 Mon Sep 17 00:00:00 2001 From: Dixing Xu Date: Fri, 6 Nov 2026 16:55:18 +0000 Subject: [PATCH] perf(schema): reduce type checks -- 31% less rebuild time Use direct class checks in TypeSet.collect_referenced_types and keep the named-type cast for static type checking only. Bind recursive calls only for types with references and skip empty built-in argument maps. Preserve traversal order, type identity, lazy lookups, and custom mappings. The native suite, seven benchmark tests, Ruff, and mypy pass.
