check / check (push) Successful in 3m40s
fx wrote its own steps of starting and stopping as plain text to stderr. It now logs them with its own slog event logger through the backend's logger, so off a terminal every line from start to stop is JSON. A config file that is found but cannot be read now makes config.New return the error instead of panicking. A test runs the server as a child process and checks that all it writes is JSON, on a normal start and stop and with such a config file. The backend logs its name, version and architecture once at start. The health check's uptime keys are now uptime_seconds and uptime_human, and its type and method take the names GO_HTTP_SERVER_CONVENTIONS.md gives. Its path, content type, status and code are unchanged. Model: opus-5-5
