meshDelivery
Peer-to-peer delivery with no relay hop.
A fabric declaring meshDelivery = true that supports three or more peers MUST also subclass MeshConformanceSuite (which exercises N-peer roster convergence, broadcast sender-attribution, directed routing, peer-leave, and dial dedup) — SeamConformanceSuite is fixed at two Looms by ADR-001 and cannot host a third peer. A strictly 2-peer fabric may declare meshDelivery = true vacuously (no third peer to relay to) and records that vacuity in its capability-matrix entry. This obligation is enforced by the capability matrix (meshEvidence, see CapabilityMatrix), not by a runtime meta-test.
