 6. **The `talk` field on mobs** lets you talk to them directly — `talk guard` finds the guard mob, no duplicate object entry needed.
 
-7. **Exits accept both `int` and `map` formats.** `north: 2` is shorthand for `north: {room: 2}`. Add `condition` and `blocked_message` only when needed. Mob room entries accept both `"man"` and `{id: man, ...}`.
+7. **Live editing works.** Room, item, mob, object, and behavior YAML files are read from disk on each access. Change a room description or dialog and it takes effect immediately — no restart needed.

-11. **Use triggers to decouple cause and effect.** Objects set flags; triggers watch flags. This way the same "pull lever" action can spawn a boss in one room, open a door in another, and broadcast to the server — all by watching the same flag from different triggers. Room triggers keep local events local; global triggers (`data/triggers/`) handle server-wide events.
