deck.yml

name: Deck model

# The extra `deck` pins the deck model, the package ournotes-sim that ournotes-deck publishes with each release, so
# that one nnnotes version always carries one deck model. The pin follows ournotes-deck's releases: when the latest
# release has published its replay and recommendation WASM packages (the engines of music-data --replay-engine and
# --recommend-engine) and its ournotes-sim wheels, and it is past the pinned release, this opens a pull request that
# moves the pin and dispatches CI and the commit message check on its branch (a pull request opened with the workflow
# token starts no workflow by itself); their checks land on the pull request.
