name: Cross-library benchmark
# Audit finding R10: previously the cross-library benchmark ran on every push
# and every pull-request to `main`, adding 510 minutes of build + bench time
# per CI run with no consumer of the resulting artefact. The benchmark is now
# scheduled (nightly at 03:00 UTC) and on-demand via `workflow_dispatch`. The
# CI pipeline proper (.github/workflows/ci.yml) still verifies build / tests /
# lints on every push and pull-request.
on:
schedule:
# Nightly at 03:00 UTC. Pick a slot well away from common European /
# American working-hours pushes to keep this off the critical path.
