| # 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 | |
