发生了什么
When prefer_deferred_runtime_asserts_over_guards=True, Dynamo records backed-SymInt shape checks as deferred runtime asserts instead of guards. FX materializes those backed-only checks as input-graph aten._assert_scalar nodes, but regular Inductor lowering dropped those nodes. Only the AOTI full-runtime-assert path converted input-graph _assert_scalar nodes into wrapper AssertScalar operations, and the unbacked-symb…
