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.
