Struct SchemaProbe 

pub struct SchemaProbe<T>(/* private fields */);

Opt-in schema derivation for accumulator/reactor boundary types (CLOACI-I-0128 Task D).

Unlike workflow params (whose types we control via #[workflow(params(...))]), computation-graph boundary types are defined in the author’s crate and may or may not derive schemars::JsonSchema. We do NOT want to force the derive — so the #[computation_graph] macro can’t unconditionally call schema_for (that needs the bound at compile time).

Instead the macro emits a probe over SchemaProbe<T> that, via autoref specialization (the stable-Rust dtolnay pattern), resolves to the real schema when T: JsonSchema and to a permissive {} (“any”) schema otherwise. Authors opt a boundary type into rich typing simply by adding #[derive(schemars::JsonSchema)]; types without it degrade to name-only slots rather than failing to compile.

Usage (what the macro emits)

{
    use ::cloacina_workflow::input_interface::{ProbeTyped as _, ProbeFallback as _};
    (&::cloacina_workflow::input_interface::SchemaProbe::<MyType>::new())
        .probe_input_schema()
}
