Segment 7

In this sub-session, we systematically resolved a cascade of failures in the Ansible-based deployment of Filecoin Gateway clusters. Key fixes included: removing `export` prefixes from `settings.env.j2` to satisfy systemd's `EnvironmentFile`, correcting the log level pattern from `*:*` to `.*:.*`, excluding hidden dotfiles (`.gitkeep`) from wallet file copy tasks to avoid binary parsing errors, and eliminating duplicate CQL table creation by letting the `kuri init` handle migrations instead of the `yugabyte_init` role. Additionally, we fixed a non-existent Ansible filter (`format_backend_url`) in the `s3_frontend` role and disabled `pam_nologin` in the test containers by setting `systemd-user-sessions` to ignore. After rebuilding the Docker images and rerunning tests, all stages passed: connectivity, YugabyteDB init, Kuri node deployment (both nodes with health checks), and S3 frontend deployment. The session concluded with commit `806c370` encompassing 19 file changes that harden the test harness and resolve observed regressions, yielding a repeatable, validated cluster deployment pipeline.
