ci: route remaining heavy workflows to self-hosted (Phase 2, fork-gated) - #551
Merged
Conversation
Reclaim GitHub-hosted machine-hours by routing the remaining heavy workflows onto the self-hosted fleet proven out by #439, using the same fork-gated runs-on expression (self-hosted for push/internal-branch PRs, GitHub-hosted fallback for fork PRs). - coin-matrix.yml (coin smoke matrix) -> self-hosted Linux / ubuntu-24.04 fork fallback - codeql-analysis.yml (Analyze legs) -> self-hosted Linux / ubuntu-24.04 fork fallback - attribution-gate.yml -> self-hosted Linux / ubuntu-latest fork fallback - safe-cosmetic-automerge.yml (evaluate) -> self-hosted Linux / ubuntu-24.04 fork fallback Build-env parity with build.yml on the two building jobs (coin-matrix, codeql c-cpp manual): clean stale reused build dir on self-hosted (rm -rf build_<coin> / build_codeql) to avoid stale gtest_discover exit-8, and skip apt system-deps on self-hosted (preinstalled). Per-coin source-presence guards (PR #47) untouched. CI plumbing only, no consensus/coin-tree changes.

Phase 2 — route remaining heavy workflows to self-hosted (fork-gated)
Follow-on to #439 (build.yml self-hosted switch). Reclaims more of the
~95.6% machine-hours still on GitHub-hosted by routing the remaining
heavy workflows onto the self-hosted fleet, using the same fork-gated
pattern as #439: self-hosted for push / internal-branch PRs,
GitHub-hosted fallback for fork PRs.
