The delivery repository's contracts and SDK live under modules/ as mesh-delivery-contracts and mesh-delivery-sdk, their Go module paths renamed to match the folders (the TypeScript names already did), and every importer in mesh-delivery, mesh-catalog, mesh-host, mesh-tools and mesh-sdk follows in the same group: a design as it should be, one path per module, checked by the group's check building every importer.

// Package kept holds what the layouts of the Delivery domain's kept values share: the reading of one at its version and the form

// of a digest. It names no seat and no module (ADR 0634 §2). The version (keys.Version, keys.CheckVersion), the rule a name
|
|
// must keep to be a key part (keys.CheckName), keys.IsHex64 and the escaping of a name (keys.EscapeName) are mesh-sdk's,
|
|
// since more than one domain uses them.
