What it is
Protocol for inter-agent coordination in autonomous swarms. Specifies handshake, scope handoff, and conflict resolution between agents that share a substrate but were authored separately.
Underlies the AXON multi-worker swarm and is intended to generalize to any CSR-class swarm.
Where it sits
ACP is catalogued under Infrastructure & Platforms in the instrument registry. Instruments in this group share a concern and are frequently composed rather than used alone; the related entries below are the nearest ones.
This is a registry entry: a real instrument, documented here, without a public endpoint a stranger can open. Pages carrying source excerpts and measured results are marked as such in the catalog. If you want detail on this one specifically, ask about it directly.
