The app read its TLD set from /api/tlds `advertised` — the legacy nine — so a name under a newer registry TLD was intercepted only once the local index already carried it. It now reads `routable` (falling back to `advertised` for an older gateway) and ships a bootstrap list matching today's routed set for cold start. The cold-start snapshot it pulls from dl.silentmode.st was produced by publish-name-mirror.mjs, which needs the operator wallet and ran by hand: the CDN copy was sixteen days and seven names behind. cdn-name-index.mjs now reshapes the gateway's own /api/registry into the snapshot format on the VPS every ten minutes (systemd timer in VPS/SilentMode), so no wallet and no hand step are involved.
