The AMM subgraph has been indexed and at chain head the whole time; nothing read it. /dex queried only the native CLOB at 0x9999, which has genuinely never emitted an event, so the page reported MARKETS 0 / VOLUME 0 while ~1 swap per block was landing in the WLUX/LZOO pool. Wire the amm subgraph in as a SECOND venue rather than folding it into the first. The two are different exchanges and their figures are never summed — each section reports only its own state, so "live" can never be borrowed by the venue that is not trading. Swaps were rendering as anonymous EVM traffic; they now read as trades: pool-signed amounts resolved into sold/bought, scaled by each token's own decimals, with symbols, pair, fee tier and links to sender, block and txn. Status uses the words already in use elsewhere (useNetworkValidators, useFeeSplit) — live/idle/empty/unavailable/unknown — defined once in lib/api/venueStatus. There is deliberately no 'stale': separating a stalled indexer from a quiet venue needs an indexer head this API does not serve. Also decomplected while here: one fetcher for both subgraphs, and an unreachable endpoint is no longer flattened into "empty" — an outage and a venue that has never traded are different facts and now render differently.

// How much we actually know about a trading venue. Every word already carries
|
|
// this meaning elsewhere in the codebase (lib/api/pchain/useNetworkValidators,
|
|
// lib/api/cchain/useFeeSplit) and keeps it here:
|
|
//
|
|
// 'unavailable' — the indexer never answered, so we learned nothing at all.
|
|
// 'unknown' — it answered, but the chain head is unreadable, so we cannot
|
|
// judge how recent its newest trade is.
|
|
// 'empty' — it answered and has never recorded a single trade.
|
|
// 'idle' — it has history, but nothing inside the recent window.
|
|
// 'live' — its newest trade is inside the recent window.
|
|
//
|
|
// There is deliberately no 'stale'. Telling a stalled indexer apart from a
|
|
// quiet venue needs the indexer's own head block, which this API does not
|
|
// serve, so claiming that distinction would be a guess.
