- Remove the Node status chip from the wallet-list header; the integrated node now lives in the cog's settings as a status + Enable/Autorun section, with a "Node settings" button into the full stats/mining/tuning panel. - Stop the desktop two-column rail from auto-docking the node beside the settings screen, so the node has a single home in the cog at every width (the full panel opens only on demand). Fixes the wide-window double-exposure. - Prove NIP-17 payments transit the top public relays: parameterize the nostr e2e roundtrip and add damus.io + nos.lol proofs (3/3 green). - Add DEVELOPING.md documenting how we iterate and test (Xwayland :2 recipe, Build N cadence, gui-sweep, e2e tests, live infra) — no secrets. Verified live on :2: chip gone from the list; cog shows the node once (single column, no left rail); "Node settings" opens the full panel on demand. 34 lib tests green; nip17 roundtrip green over nrelay + damus + nos.lol.
