`ServerMessage::IntentsSwap` carries the trade exactly as /intents/swaps returns it — one conversion, `intents::to_swap`, serves both, so the route and the push cannot describe the same trade differently. Only trades read within LIVE_WITHIN_BLOCKS (~a minute) of NEAR's final tip are pushed. The backfill never broadcasts, and the threshold is what keeps an upward catch-up after a restart from announcing an hour of history as news — the confusion the wormhole pulse shipped once already. The market panel re-reads its figures on each push rather than adjusting a copy: a VWAP over the latest N trades drops its oldest as it gains one. Verified by replaying the trade at NEAR 218,261,895 with the threshold opened locally and catching the frame on /v1/ws.
