Enum LvalueSpec 

pub enum LvalueSpec {
    Wildcard,
    Explicit(String),
}

Workload-author lvalue assertion attached to a BindPoint::Reference.

Spelled as a :<spec> suffix inside the brace pair:

• {meta} — no marker; strict match. The adapter consults cluster-side metadata and the binder verifies the wire’s rvalue type matches that.
• {meta:*} — wildcard. Polydat is licensed to fuse / coerce; the binder treats the slot as Str-lvalue (which permits any rvalue per the load-bearing rule).
• {meta:<type>} — explicit polydat PortType assertion. The binder uses the asserted type as the lvalue for verification, overriding what cluster-side metadata would say. The type name is the lower-snake-case form (u64, i32, f64, vec_f32, str, bytes, etc.) — matches PortType’s Display form.

Variants

Wildcard

:* — workload-author opt-in to type fusion.

Explicit(String)

:<typename> — workload-author asserts a polydat PortType by name. The string is preserved verbatim; adapters parse it to PortType at construction time and error on unknown names.
