Staying one mind when the radio fails.

A fleet is most useful when what one aircraft learns, the rest know. In the field the link between them is slow, lossy and sometimes jammed. The fleet has to share learning over that link, and keep working without it.

Small enough to cross

A new fact crosses as a binary update of a few hundred bytes, not the whole store of knowledge, so it fits a radio link that carries only kilobits a second.

Hard to stop

The link hops across frequencies to ride through interference. On an emulated 32-channel link between two cloud machines, facts still arrived with a jammer covering 75% of the band; only jamming the whole band stopped them.

Unreadable in transit

Updates are encrypted and authenticated with ChaCha20-Poly1305, so a listener learns nothing and a tampered update is rejected.

Whole again afterwards

In the recorded run, a machine cut off from the link recovered a fact taught while it was away as soon as the link returned.
