"""Spoolman slot requests the database would refuse are refused up front (SSA-8, SSA-9).

An ams_id the table's CHECK does not admit (it allows AMS units 0-7, AMS-HT
128-191 and the external slot 255) came back as a 500. The link route also
wrote the spool's tag to Spoolman before the local insert failed, leaving a
half-applied link. And an archived Spoolman spool could be assigned to a slot,
then charged the next print's usage; the built-in inventory refuses that.
