First read-only compiler-API reflection readers, bound the same way as the intern/text_of seed (compiler_lib.bound_fns + Vm.callCompilerFn, native on flat memory, no marshaling). A type handle is a plain u32 TypeId (like StringId), so both stay clean scalar host-calls: find_type(name: StringId) -> TypeId (TypeTable.findByName; unresolved/0 if absent) type_field_count(t: TypeId) -> i64 (new TypeTable.memberCount; loud-bail, no silent 0) memberCount is the single source both the legacy handler and the VM read, so the two paths can't drift. find_type returns a non-optional TypeId using the unresolved(0) sentinel for not-found rather than ?Type — a Type value is .any-typed (which the flat-memory VM does not represent) and an optional can't cross the legacy<->VM eval boundary; unresolved is the project-blessed "no type" marker. Example 0628 chains intern -> find_type -> type_field_count (+ a not-found lookup), folded at #run, VM-HANDLED natively. VM unit test added. Parity 689/689 (gate OFF and -Dcomptime-flat).
