Glad you like the compliance suffix.
W.r.t observability: We don't use any third-party error tracker, APM, or queues. If any request fails, the client gets an error message that we write as opposed to the raw provider error. On our side, every log lives inside our boundary, and is written from a field allowlist (ids, model, token counts, status, latency). The JSON is purposely stripped away so any details in the request do not land in our logs.
