name: Coverage

# Weekly cargo-llvm-cov sweep. Non-blocking by design — the goal is
# visibility into which functions in perry-codegen / perry-transform /
# perry-runtime have 0% test coverage so we can fill the gaps, not a
# regression gate. (#795 / part of #793.)

on:
  schedule:
    # Mondays at 04:00 UTC — runs after the Sunday-night benchmark
    # window so we don't fight a 1-vCPU runner with two long jobs.
