FIELD · LATER
Wide areas, sparse radio, no backhaul for hours.
Farms, mines and construction sites spread robots over distances where one hop is long and a backhaul is occasional. SwUM is built for that: records wait on the robot, and the chain only sees them when a gateway comes within reach.

Long hops, bigger radios, and a chain that can wait.
CLASS M AND L RADIOS
Field work starts when the larger radio classes are proven: LoRa and ESP-NOW frames of 250 bytes, or a Wi-Fi mesh at 1,200. The protocol does not change.
GATEWAY WHEN AVAILABLE
Any robot with backhaul is a gateway. Several may exist at once, and duplicate submissions are harmless by design.
LEARN BETWEEN SHIFTS
Idle time is training time. Outcomes stored on SNIP improve the bidding model and the selector at the next epoch.
THE LOOP
Proof goes to the chain. Data goes to storage.
A finished job becomes a signed attempt record. Records are bundled, and the bundle hash is anchored on SUM Chain when a gateway is in range. The success and failure data goes to SNIP as an episode pack, and a robot with no job trains on it through OmniNode. Nothing is thrown away: even a duplicated job is training data.
DENSITY
The beacon period adapts to how many robots can hear each other.
With 16 robots in range on a small 802.15.4 radio, beaconing twice a second loses about a fifth of frames to collisions, and once every 1.2 seconds costs a tenth. Proposition 11 gives the number for any deployment, and the communication model learns the period inside a fixed range.
Sparse field sites sit at the easy end of that table.
WHEN
Starts when the bigger radios are proven.
Field deployments wait for the class M and L radios to be proven on the bench and in the factory pilot.
Perception and motion control stay out of scope: the drive controller is a device that accepts velocity or waypoint commands.
