# Use the GitHub Actions cache to store the minimal persistent state we
# need (a hash of the state data). Cache entries aren't durable—they
# can disappear by eviction or manual deletion or transient failure—but
# the worse that happens is we see duplicate messages in Slack until we
# re-cache.
#
# Since cache entries are immutable once stored but we need to make
# updates, we use a unique cache key per workflow run and thus always
# store each run's state hash at the end of the run. We restore from
# the cache entry of the lastest previous workflow run since the
# current run's unique key won't exist in the cache yet. This is a
# documented workaround to cache immutability.¹ It will grow the cache
# size both in number of entries and storage use over time, but that
# seems fine. Entries which haven't been accessed in 7 days will be
# evicted, and if we hit the 10 GB¹ total size limit for the repo, the
# oldest entries will be evicted first.²
