Enum WaitOutcome 

pub enum WaitOutcome {
    Passed,
    Failed,
    Inconclusive,
    Landed,
}

The result of waiting on a review’s checks before merging it.

Variants

Passed

Checks passed, or there are none - go ahead and merge.

Failed

A required check failed - stop the run.

Inconclusive

Checks stopped without a verdict - a cancelled run, or one waiting on a person. Nothing failed, but nothing passed either, and the platform still holds the merge, so the run stops and says which it was.

The same distinction CheckStatus::Inconclusive draws for the dot, and deliberately so: a provider decides both, and the two must agree about one commit or the gate contradicts the dot the user just read. Where a provider’s gate cannot see the difference on its own - GitHub’s reads gh pr checks exit codes, which have no code for it - it asks the same rollup the dot came from.

Landed

The review merged out-of-band while we waited (an admin merge on the web, say). Skip the redundant merge and let sync reconcile it.
