What the status page is built from, readable directly. quotes.engine is the routing engine’s own state (ok, starting after a deploy, stale when its pool sync stopped, down); quotes.canary is the small quote the status probe sends. data.ageSec is how old the newest indexed trade is and data.maxAgeSec the age past which the chain’s data counts as delayed. quotes is null where Chord does not route (Solana), data is null where no tape runs.
