Enum MergeFallback 

#[non_exhaustive]
pub enum MergeFallback {
    Fail,
    InstanceSigningKey,
}

What to do when the instance cannot restrict merges to fast-forward only (Forgejo before 7, Gitea before 1.22).

Fast-forward-only merges land the PR’s own DID-signed commits unchanged, so no platform key is needed. Without it, every web merge makes a new commit that the check never saw, and the only way that commit passes a later verification is if the instance signs it and its key is exempted.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fail

Refuse: the merge-settings step fails with instructions to upgrade.

InstanceSigningKey

Allow instance-made merge commits only, commit the instance’s signing key (GET /api/v1/signing-key.gpg, fetched when the adapter probes the instance) as the exempt keyring, and pass exempt-keyring to the action. The instance must sign merges ([repository.signing]).
