| # Nightly smoke + soak load tests against an ephemeral docker-compose | |
| # stack. Catches p99 regressions before they ship. | |
| # | |
| # Phase-53 / p53-loadtest. | |
| # | |
| # Why nightly + on-demand (not on every PR) | |
| # ───────────────────────────────────────── | |
| # Each soak run takes ~6 min plus ~3 min stack boot, which would | |
| # inflate every PR's CI wallclock by ~10 min and is not actionable | |
| # on every commit. Lighthouse CI (perf.yml) already catches frontend | |
| # regressions on PRs; this workflow is the BACKEND counterpart and | |
| # runs on the schedule the SRE team can react to. | |
