+// resolveObjectDef returns the ObjectDef for a room object instance. File
+// objects (the common case) resolve through the cached object store with no
+// disk I/O on a hit, and a store miss is just a map lookup; only local objects
+// — which never live in the store — fall through to a freshly-read room, so
+// they keep live-edit semantics without slowing file-object lookups. defID is
+// the ObjState DefID (a normalized name for local objects, a file id
+// otherwise).
+//
+// Use this from display or generic-handling sites. Sites that look up a
+// specific interactable behavior (gather/use-station/safespot/steal/etc.) may
+// call ObjectStore.Load directly: local objects are guaranteed non-interactable
+// and simply fall through those sites' existing error guards.
