External spool ids 254/255 keep their identity through filament changes and RFID refresh
Orca virtual trays persist across push_status snapshots and reset on reconnect
AMS writes gate on the device's declared FMS and filament-slot capabilities
- Translate slicer AMS commands to OrcaSonar’s canonical write format
- Gate AMS operations using printer capabilities
- Refresh capabilities when filament topology becomes available
- Apply virtual-slot removals only from full status snapshots
- Add synchronization tests and document the integration
command_ams_select_tray split the BBL tray id into ams_id/slot_id inline and untested. Extract build_ams_change_filament_body so the mapping is a named unit that command_ams_select_tray routes verbatim, and lock it with a test: tray 9 (a 6-slot box's slot 5) sends (2, 1), never a fabricated flat lane.
