Editing (game port, OpenTTDClient): a core of JGRPP's scheduled dispatch DoCommands — set_scheduled_dispatch (enable/disable), add/remove schedule, add/remove/clear slots, and set duration/start date. Adds the command IDs to protocol.py. Viewing (admin, OpenTTDAdminClient.get_dispatch): the GameScript API has no dispatch support, so a new server patch (docker/patches/0002-*) adds read-only GSOrder.GetScheduledDispatch* / IsScheduledDispatchEnabled getters, an AdminBridge GameScript get_dispatch handler exposes them, and get_dispatch() returns the live schedules and slots (mirrors get_timetable). Note: set_dispatch_start_date values are normalised by the engine relative to current game time, so they read back offset from the requested value. Includes unit + e2e tests, a demo in main.py, and protocol/timetable docs. The AdminBridge GameScript and the patched OpenTTD-patches clone live outside this repo; the 0002 patch file is the durable source for the latter. Co-Authored-By: Claude Opus 4.8 <[email protected]>
