Enum TransientBuild 

pub enum TransientBuild {
    Ready(TransientSpec),
    Future(TransientBuildFuture),
}

What TransientSourceRegistry::build answers with.

Native builders are pure functions of a TransientContext and answer Ready — the menu seats in the same frame the chord was pressed, exactly as before this type existed. A WASM builder cannot: its build is a guest call on the plugin’s own actor task, and blocking the editor actor on it would violate paramount #4. So it answers Future and the host parks, then seats on the async-landed wake.

Making that difference a value rather than two registries is what keeps Effect::OpenTransient { source } one code path: the effect still carries only a name, and neither the chord nor the ex-command that emits it knows or cares which kind of builder answers.

Variants

Ready(TransientSpec)

Built synchronously — seat it now.

Future(TransientBuildFuture)

Building off-thread. Err from the future is echoed and the menu does not open.
