Field guide
Protocols, as creatures actually observed
A naturalist's field guide catalogs creatures - their habits, their habitats, what they feed on, what hunts them. This one catalogs payment protocols the same way, because a spec records a protocol's promises, and a field record shows how it actually lives.
Read the fields like a naturalist
habitat - where it operates · diet - what sustains it: volume, fees, subsidy, intent · lifespan - how long its kind lasts · predators - what kills it: regulation, concentration, starvation · symbiotes - what it depends on, and feeds in return · markings - how to recognize one in the wild
