/**
 * The game client's level editor, on a world server (docs/ZonePublish.md): the client says when its editor is on,
 * locks the zone, sends the zone's files, asks for them and asks for a reload. Everything goes through what the
 * dashboard's zone file API uses: the same checks (ZonePublish), override folder (ZoneOverrideStore), locks and
 * editors (ZoneEditLock, IZoneEditing), audit log entries and world reload. Only how the files travel is different
 * (ZoneFilePack).
 *
 * Packets are read and answered on the main thread. Unpacking, checking, writing and packing files run on one worker
 * thread, which touches no connection, database or setting and hands its result back to the main thread (Update).
