Enum ContractRequirement 

pub enum ContractRequirement {
    Version(ContractVersion),
    Unchecked,
}

What a resolution site demands of the runtime it is about to fork.

An enum rather than an Option<ContractVersion> on purpose: None at a call site reads as “nothing to pass” and gets copy-pasted into places that did have something to pass. Unchecked has to be spelled, and spelling it invites the question of why.

Variants

Version(ContractVersion)

The version the bundle’s manifest requires. The resolved runtime must advertise it.

Unchecked

Resolve without a contract check. The sidecar case: almanac-feed is versioned with yubaba and its interface is its own CLI, not the bundle↔runtime contract, so holding it to this contract’s versions would be a category error. Nothing that resolves a serve runtime may use this.
