Delivery group feat/data-items (mesh-sdk, mesh-host, mesh-catalog, mesh-delivery), one check, one Approve. Decision: ADR 0577 (the node-engine publishes each placed module's data items; disk-load watches them and composes nothing), changing ADR 0571 §5. Fixes issue 1955 in part: disk-load needed 30 to 45 minutes per round on ace, g14 and shanks, and went silent for 45 hours when its mesh-sdk refused a manifest.

Quick fix (a prefix filter in the states reader) not chosen: a fourth hand pin and more logic in mesh-sdk. Thorough fix chosen: one composer per node, disk-load event-driven.

This member: delivery/enginedata.go (state mesh-host_data, key ., value type, encode/decode) and the grants in buscompose: each engine writes only its own .> keys; disk-load reads only its node's keys. No composing or measuring logic.

The contract (state name, key form, value) is in delivery; buscompose grants the engine its own
node's keys of mesh-host_data and each node's disk-load a read of its own node's keys alone, the
same way the engine's other states are granted.
