A fresh instance (empty data volume, no printers configured yet) treated every spool whose "drucker" field named a printer as stale and moved it to storage. Now only spools at our slot locations or naming a printer this bridge runs or has written are corrected; written printer names are kept in the state (seeded from the applied locations on update).

"""Bridge between the Canvas record (SSH), CC2 Control's spool library and Spoolman.
|
||
|
||
Rules:
|
||
- The printer is only read (SSH `cat` of the canvas record). No MQTT, no printer commands.
|
||
- Writes go to CC2 Control's spool endpoints and to Spoolman only, and only when dry-run is off.
|
||
- Slot <-> spool mappings are kept by the bridge; a tag id vanishing from the record
|
||
(weight falls back to 1000 after a touchscreen edit) does not drop a mapping made by a scan.
|
||
- The record keeps a tray's tag data after the roll is taken out. A roll put back into the slot
|
||
it left, with the record unchanged, is taken to be that roll again ("reinserted"); if the
|
||
touchscreen then replaces the id, it was another roll and the mapping goes.
|
||
- Several printers: one worker each; a spool is mapped to at most one slot of one printer.
|
||
- Spoolman shows where a loaded spool is (location "<printer> Slot N", extra fields
|
||
"drucker"/"slot"); the printer wins over manual edits there.
|
||
- Consumption is the drop of CC2 Control's remaining weight, booked once the printer is idle.
|
||
CC2 Control's log adds what was printed (file, result), weigh-ins (Spoolman takes the weighed
|
||
value) and usage of a tray left without spool after "Take out" (booked to the roll still in it).
