Package golf is the game realm: it keeps the holes, the players' rounds, the records and the rankings. Every hole is data (a GG1 string, p/…/course), never code: golf decodes it and plays it with p/…/physics. The owner publishes the course's holes into slots of a cup ("garden/7"), each publish a new version ("garden/7/v2"); once the owner opens publishing, anyone can publish a community hole ("<address>/<slug>/v1", PublishMine), playable and recorded but outside the course and its ranking.
Reads take a version's id or its alias ("garden/7", "<address>/<slug>"), its current version. Writes take the exact id only, as HoleState or Holes gave it: a round cannot be replayed on a version it was not played on.
Who can change what (in full on the hub page): the owner holds one power, the course itself: its holes (Publish), what the lists show (Hide), and whether anyone can publish (SetPublishing).
SimulateRound replays a shot list from the tee, read-only, and returns its last shot and stroke count: what PlayRound would record, refusals included. Continue from an exact "rest" (SimulateFrom): rounded points are for drawing.
