Detailed Description

Bounded typed-artifact source seam implemented by the C6 port.

Separates protobuf/job orchestration from the concrete HTTPS and SHA-256 mechanism. Implementations own all network and digest state.

Invariant

Every callback and ctx is non-null after service initialisation.

At most one job is active because the portable service serialises it.

Since

0.1.0
