ci-deploy / build-deploy-test (push) Successful in 1m11s
Run 549's wait-for-health logged two HTTP 502s before its third attempt succeeded — nginx → docker forwarding hit the new container during the ~4s window between \`docker run -d\` returning and Node.js inside finishing its boot. The retry loop covered it but the log was noisy and a slower boot could blow past the 30×2s budget. Added a post-run readiness probe inside swap: poll http://127.0.0.1:${PORT}/ on the host (docker container is published to 127.0.0.1, runner uses host network mode) until it answers 2xx, up to 30 attempts × 1s. Skipped under --dry-run so the tests/ci/ shell tests still pass without touching the network. Net effect: wait-for-url against the public URL now succeeds first attempt, and the run aborts cleanly if the SSR doesn't come up at all instead of looking healthy because nginx happens to keep a warmed connection.
