On the engineering computer, run +æ://fleet offer. A QR carries the node's capability manifest: ae://fleet?host=<name>&mesh=pc://mesh/<name>/local&models=<csv>&role=engineering-computer.
On a device, open fleet.html, scan (or paste) the offer, then run +æ://fleet join <manifest> on the engineering computer to register it.
The node joins the mixture of devices. Each node advertises models (MoM) + agents (MoA); the router selects across them.
Dispatch via +æ://route <task> — chooses device × agent × model, opt-in, no cloud broker. Local-default.
