Realtime

usesRealtime, generateAstroidEditSession, generateAstroidRealtimeEnv, ASTROID_REALTIME_BINDING, ASTROID_EDIT_SESSION_CLASS, ASTROID_REALTIME_MIGRATION_TAG.

The per-page live editing session (ADR 0002), opt-in via modules: ["realtime"]. Astroid generates the wrangler durable_objects binding + migration block, mounts realtimeRoute, and scaffolds the DO subclass—which is scaffold-once because it imports cloudflare:workers and because its persist is the seam you tune.

Note realtimeRoute comes from louise-toolkit/realtime, not /editor: it is the one factory in the route plan that isn’t an editor route.
