# Nightly compiler-cache warming for main's scope. GitHub cache isolation
# lets a PR restore only caches written by its own ref or the base branch —
# and nothing used to write test caches in main's scope (the test workflow
# runs on pull_request and workflow_dispatch only), so the cross-ref
# fallback restore keys in _test.yml had no warm source and every fresh PR
# built cold. This build-only job (no tests) keeps main-scoped caches at
# most a day stale; CCACHE_COMPILERCHECK=content turns staleness into
# partial misses, never wrong output. The build commands and ccache
# environment mirror scripts/test.sh's build phase exactly — a warm entry
# only hits when flags and compiler content match, so fidelity here is what
# makes the cache useful.
