Where it lives
- Signature:
src/builtins/types/intval.rs - Lowering:
src/builtins/semantics.rs:639 (lower_registry_call) - Function symbol:
lower_registry_call()
Lowering notes
- Uses the
eir_graphstrategy from the single-source builtin descriptor. - Emits backend-neutral EIR primitives or a small EIR graph through
BuiltinLoweringContext.
Semantic descriptor

EIR and runtime boundary
- Typed EIR target: descriptor-emitted EIR primitives or graph; no opaque builtin call remains.

- Arity: takes 1–2 arguments (1 optional).
Eval interpreter (magician)
- Declaration:
