# Every fetch leaves a copy behind for a reader that cannot afford the round
# trip - the bar panel's model picker. It is written here, in the only places a
# catalogue is ever fetched, so every command that already pays for the network
# (models, doctor, setup, the menu's picker) keeps it fresh at no extra cost.

# catalogue.kind, parsed to TSV, and left in the cache for the panel. Prints

# the list most.
