What is listed and when it trades.

### Pairs

Every pair on Ostium. Use `id` wherever a request takes a `pairIndex`, and the symbol wherever
one takes a `pair`. Do not infer the id from a row's position — read the column.

A pair marked `not yet` in **Tradeable** is listed on chain but has no open-interest ceiling, so
it cannot be traded and `GET /v1/depth/{pair}` answers `503` for it (the `/quote`
sub-resource still prices it, with `availableNotionalUsd: 0`). It is shown rather than hidden so
the ids either side of it stay right.

Note `GET /v1/pairs` returns the subgraph's own spelling in `from`/`to`, which for renamed
assets is the legacy one — `SPX` where this table says `US500`. The table uses the symbol the
price and depth endpoints expect.
