The Signature Mechanism · Node & Chain Topology
ONE PACKABLE NODE — A CHAIN THAT CAN CHOOSE ITS SHAPE
Every node is the same packable unit: a sectional mast carrying an antenna,
a solar-fed power module, a GNSS positioning bay, and a radio, all planted on an anchor-and-guy
kit sized to the ground it stands on. Erect one, and it relays. Erect a line of them, and
they form a chain.
The chain can be built two ways, and the choice is stated as an open design fork rather
than a settled answer neither engineering study has earned. Wired in a line — a linear
chain — every node and every link must hold, and losing one severs everything downstream.
Wired with alternate paths — a mesh — the chain can route around a lost node, but only where
a second geometric path actually exists. On a narrow incised coastal valley, that is a real
question, not a marketing one: there may be exactly one ridge line with the sight lines a
link needs, and no amount of engineering invents a second one where the terrain doesn't
offer it.
When a link is under strain, the shed order is design intent, not a frozen specification:
data backhaul goes first, position augmentation second, and command and telemetry relay
last — the machine's command link is built to be the last thing the chain gives up.
topology — linear vs mesh, an open design fork
loss-of-link shed order — design intent, not yet a specification
