Module mesh_cog 

Cog checkout and artifact transfer over machine-mesh deliveries (ADR-106 sections 4 and 5, phase 1c).

CogMeshDelivery sits in front of the daemon’s router. It takes the three topics of this feature, whatever their sender, and hands everything else on untouched:

• mesh.artifact.tunnel: artifact piece frames (ArtifactTunnel);
• mesh.cog.checkout: a member’s request to the steward;
• mesh.cog.checkout.reply: the steward’s answer.

In service mode it also takes the licence control topics (mesh.cog.binding, mesh.cog.grant, mesh.cog.sync) and hands them to the node’s ServiceLicenceLinks (ADR-106 phase 3); they are never passed on to the router.

Every one of them is honoured only from a verified node peer. The PeerCtx is built by the daemon from the service-stamped origin, so LocalTenant and Unadmitted deliveries never reach a handler, and are dropped here with a count instead of an error the sender could observe.

Structs

CogMesh

One node’s cog mesh: tunnel, optional steward relay, requester side.

CogMeshCounters

Counters, all monotonic.

CogMeshDelivery

The router in front of inner that takes the cog mesh topics.

CogMeshSlot

A slot the daemon fills once its exchange exists (the mesh link starts before placement builds the exchange). Until then feature topics are dropped.

Constants

TOPIC_CHECKOUT

Topic of checkout requests to the steward.

TOPIC_CHECKOUT_REPLY

Topic of the steward’s replies.
