// The meters the platform charges for that are NOT priced anywhere else.
|
|
//
|
|
// Two products already have an authority and are deliberately absent:
|
|
//
|
|
// ai — a model's price is a ModelRoute row (InputPrice/OutputPrice),
|
|
// resolved org-first and read AHEAD of config and the compiled table.
|
|
// A second source here would make two rows answer one question.
|
|
// tools — a tool's price is its marketplace LISTING, set by the publisher who
|
|
// is paid for it. A platform rate card cannot price someone else's tool.
|
|
//
|
|
// What is left is the platform's own metered work, and each one is currently a
|
|
// compiled constant plus an env override, with the same eight-line resolver
|
|
// copied beside it. That shape has no audit trail and no way to answer "what did
|
|
// we charge in March", because an env var keeps no history.
|
|
//
|
|
// SEEDED VALUES EQUAL THE CONSTANTS THEY REPLACE, so adopting this changes no
|
|
// charge. The rows exist so a price can be MOVED deliberately, in one place,
|
|
// with a record of who moved it.
|
|
//
|
|
// It is not seeded from @hanzo/plans, and that is deliberate: services.json says
|
|
// of itself that "nothing bills off this file, and a number here must never
|
|
// become a grant". Those are display rate cards for the pricing page. A billing
|
|
// number and a marketing number are different facts that happen to agree today,
|
|
// and the estate already decided they must not share a home.
