# Each job is one step of the plan: the same image, command, tools and
# packages, given only the step's inputs. A job skips its work when it has
# already passed with the same inputs.
#
# What does not carry over:
#  - The script looks at the branch. Whether it is main carries over; any other
#    rule about branch names does not, and every other branch is treated alike.
#  - Passes are remembered in this repository's Actions cache, which GitHub
#    scopes by branch and evicts when old. starci's own store has neither
#    limit.

#
# What does not carry over:
#  - The script reads ctx.ref, so its plan depends on the commit. This file is
#    the plan for a commit about which nothing is known, and is the same for
#    every push: steps the script would add or drop for a particular branch or
#    set of changed files are not represented.
#  - Passes are remembered in this project's CircleCI cache, which expires.
#    starci's own store does not.
