Enum Doubt 

pub enum Doubt {
    Announced,
    Inconclusive,
}

Why one effect’s outcome is unknown.

Two shapes, and an operator investigates them differently: one says the runtime never heard back, the other says it heard back and was told nothing useful.

Variants

Announced

Announced, and no terminal record follows.

The crash shape: the request was sent and the process died before the answer could be written. Nothing about the call is known beyond the fact that it left.

Inconclusive

The attempt concluded, reporting that it could not tell.

A timeout, a dropped connection mid-write, a probe that came back empty. Distinct from the announcement shape because something did report — there is a message to read, and a provider that has already been asked once.
