# This list feeds the cache key hash of BOTH the repository cache and
# the disk cache (see config.js: diskCache.files spreads
# repositoryCacheFiles). The default is MODULE.bazel + WORKSPACE* only,
# which never changes when we bump a module - so the key never rotates,
# and setup-bazel skips the save on an exact key hit. Result: both
# caches freeze on their first entry and go stale without ever failing.
# Keep this list in sync with anything that invalidates Bazel action
# keys or the set of fetched module sources.
