Side B is a targeted, real bugfix: it correctly forces OAuth when credentials exist, adds retry-on-401/403 logic with token refresh, improves error reporting, pins the base URL in fly.toml, and includes a new test validating the error-truncation logic. Side A merely adds unintegrated scaffold files (Dockerfile, deps.edn, event_log.rs, views.rs) that aren't wired into the build and provide no demonstrated behavior or fix, offering speculative seed code rather than lasting, verified value.
