+- Optional scalar fields MUST use pointer types with `omitempty` (e.g. `*int`, `*uint`, `*float64`, `*bool`), not non-pointer scalars.
+- Semantics MUST be:

+  - field explicitly set to zero/false => non-`nil` pointer => must still be sent upstream.
+- Avoid using non-pointer scalars with `omitempty` for optional request parameters, because zero values (`0`, `0.0`, `false`) will be silently dropped during marshal.
