check / check (push) Waiting to run
The prefix distribution was the last query on the stats path. It read one index entry per live route on every request, so on a large database it took the whole 4-second deadline and /api/v1/stats answered 500. The distribution now lives next to the in-memory counts: seeded once at startup from the same query, then kept exact by the live-route writes. A new route whose prefix had no live route adds one at its mask length; a delete that leaves a prefix with no live route takes one away. Each check is one lookup on the prefix index, made only for new and removed routes, inside the write. Model: opus-5-5
