/ stewcer [client-server]

A stewcer^{^} (from 'stewc server' [server]*) acts as the coordinator in folding loopstring➿ (among other types of braneware).** A runtime node. ^^ aka stew choreographer.

Essentially, a stewcer is a resource ("trainer") which uses a jukebox [client] for iterative transactions (ie. inbetweens).++Its role (jukeboxing) is to assist in proofing QQ. Generally-speaking, the stewcer is a clone or surjective clientele whose privilege supersedes that of player but not the impresario within stewcing ludology. Note, however, that the impresario itself may also be a stewcer (as would be the case in tournament mode).
/// Stewcers - as contractors - are considered the 'orchestra' to The Origamic Symphony🎶.

In UUe-talk, the stewcer (a type of puzzler🧩)'s objective is to devise and/or apply patches, thereby directly contributing to the fitness of the kernelspace. This means that a juker's role lies in the generation of walks (pitch establishment) as it pertains to sourcing their own tokens. Jukers are rewarded according to rules set forth by the UUelcome License. (see Black and White, clone, KOALA🐨, 🥚Egghead, stewcer's ruin)

/ merchant

A merchant [store]^@ is an account [client state] that partitions a coupon by accepting ¢ents🪙 (a charge^{^}) in an exchange with a vendor (on a shared "peer-to-peer" router).@@ An interface. ^^ hypercurrency Merchants, in turn, residually stabilize (anchor⚓) the tempo.
/// Each merchant acts as its own UUallet host. Merchants activity is represented by inflection points (tips) on a graph of the current.

To qualify as a merchant (bank=yes), the account must transact a minimum of one (1) coupon* in any given period (2600 seconds), or else it reverts to no bank status.** Active with a value of at least one ¢ent. (see u-u economics)
/// A vendor may simultaneously be a merchant, and vice versa.

/ vendor

A vendor [catalyst] is a juker [server state] that vends a token and circulates ("spends") it into an economy by way of a coupon (on a shared "peer-to-peer" router). The time for exit (ie. merchant acceptance of coupon) is correlated to earned ¢ents🪙 (1 ¢ent🪙 = 1 second).

A vendor's status is active only and immediately after an opus closes🔒 (ie. ¢ents🪙 become transferable when a yield is obtained). (see Black and White, parimutuel, coupon, u-u economics)
/// Vended ¢ents (hypocurrency) are circulated ("spent") at the point-of-distribution with a merchant.
