Closes the gap between "the harness exists" and "the harness blocks bugs." Phase 2 of the harness roadmap (per tests/harness/README.md): make harness-based E2E a required CI check on every PR touching the tenant binary or the harness itself. Trigger: push + pull_request to staging+main, paths-filtered to workspace-server/**, canvas/**, tests/harness/**, and this workflow. merge_group support included so this becomes branch-protectable. Single-job-with-conditional-steps pattern (matches e2e-api.yml). One check run regardless of paths-filter outcome; satisfies branch protection cleanly per the PR #2264 SKIPPED-in-set finding. Why this exists: 2026-04-30 we shipped a TenantGuard allowlist gap (/buildinfo added to router.go in #2398, never added to the allowlist) that the existing buildinfo-stale-image.sh replay would have caught. The harness was wired correctly; nobody ran it. Replays as a discipline beat replays as a memory item. The CI pipeline: detect-changes (paths filter) └ harness-replays (always) ├ no-op pass when paths-filter says no relevant change └ otherwise: checkout + sibling plugin checkout + /etc/hosts entry + run-all-replays.sh + compose-logs-on-failure + force-teardown Compose logs from tenant/cp-stub/cf-proxy/postgres are dumped on failure so a CI red is debuggable without re-reproducing locally. The trap in run-all-replays.sh handles teardown; the always-run down.sh step is a belt-and-suspenders against trap-bypass kills. Follow-ups (not in this PR): - Add this check to staging branch protection once it's been green for a few PRs (the new-workflow-instability hedge that other gates followed). - Eventually wire the buildx GHA cache to speed up tenant image builds — currently every PR rebuilds the full Dockerfile.tenant (Go + Next.js + template clones) from scratch. Acceptable for now; optimize when the timeout-minutes:30 ceiling becomes painful. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
