One Mind - coordination without communication
To fly as one, these drones have to agree on who takes which spot in the formation. Normally that means radioing each other to sort it out. These never do. Each drone works out the entire plan by itself, and because they all run the exact same math, they all reach the identical answer - so they agree perfectly, with zero messages between them. That is the whole trick, and it is why you can’t jam them apart. Watch them form up below, then try to break them.
A mission certificate binds the swarm’s exact inputs (roster seed, formation, adversary set, tick) to the SHA-256 of the final decided state, and signs that digest with Ed25519 in your browser. Verification re-executes the whole deterministic mission from the sealed inputs, recomputes the digest, and checks it matches the one that was signed - so a valid certificate is a re-runnable proof, not a stamp you trust. Change one drone by one fixed-point unit and it is caught.
The same claims the engine ships with, checked live: integer consensus holds where float fractures; every spoofer up to 49% is caught with zero false positives (even a 2 cm lie); two independent bodies produce a byte-identical plan; the certificate verifies and any tamper is rejected.
Honest scope. The decision path is 0-ULP integer and bit-identical across bodies and re-runs (that is what the self-test proves). The Byzantine result is structural, not a contest: each drone’s slot is derived from the commanded centre, never from a peer’s reported position, so a position spoof has no channel to drag an honest drone - and because the honest next move is an exact integer function, any lie is caught by recompute with zero tolerance and zero false positives. Consensus survives to 49% compromised; a true ≥50% majority can define its own reality (stated plainly). This page runs the real swarm.organism / swarm_max logic ported to BigInt; the production stack (one_mind/flight) carries the same law to 200,000 drones in one bit-identical decision, to real MAVLink, and to signed mission certificates.
