- One worker per printer (name, IP, CC2 Control URL, own pinned host key); a spool sits in at most one slot of one printer, moves between printers - Spoolman: location "<printer> Slot N" plus extra fields "drucker"/"slot" (created by the bridge), cleared and "Lager" on removal - Full comparison every minute: the printer wins over manual edits of loaded spools; stale printer locations go to storage; own locations untouched - Automatic migration of v1 settings, state and host key - Status hint when a tag is still in a tray but unmapped (e.g. after "Take out" in CC2 Control) - SSH test: connection drops during exec give a clean error, not a 500 - Mock environment with several printers; tests for all of the above Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014GcEk5tkfFSYD6NTF66NkC
