uECSA

uECSA is the metered credit unit of the ecsa utility-network, the substrate every other space requires to operate. One unit of its utility equals one verified economic state-change. uECSA is not an instrument of the ECSA token; it is the underlying.

What the unit meters: the substrate's utility is the metering and multilateral verification of economic state-changes — like gas for a transaction, or tokens for an inference call, denominated in the network's own endogenous unit. Every member stakes into the substrate on joining; every operation in every space consumes its credit. Demand is therefore usage itself, structurally independent of capital inflow.

How it is earned: operating contributions that sustain the substrate's utility (validation services, data feeds for utility computation) are rewarded in newly issued uECSA; holders of Stake, which is earned through contribution and non-tradable, receive distributions from the network's utility surplus in uECSA. Not proof-of-work, not narrative asset creation: metered contribution.

Character: a flow unit, designed for circulation and use rather than hoarding, and internally valued. Because all utility credits are transitively exchangeable at the network's own relational valuations, the substrate is the universal convertibility hub, and uECSA's value is emergent from the network's graph, not a price imposed from outside. It is a metered right of usage: non-transferable outside protocol operations, not listable on capital exchanges.

Two retired glosses, killed explicitly: uECSA is not "the network utility" (it is the credit unit that meters the utility), and there are no "two instruments of ECSA" (the token's only relation to uECSA is the claim structure of the bridge). The underlying is not a story; it is specified.

uECSA is economic space agency as computational utility: the capacity to act economically, rendered as a metered unit.
