Fixed
- Relays that answer a failure with HTTP 200 plus an error envelope no longer die as an opaque envelope-validation rejection. A transient envelope (rate limit, overloaded, timeout) now enters the absorb window and is retried inside the proxy; a deterministic envelope (authentication, billing, invalid request) passes through with the provider's explanation and a terminal disposition. Responses terminal bodies that carry their own error member keep the native failed-response path.
- A Cloudflare shield challenge in front of a relay (cf-mitigated: challenge or a Cloudflare-served challenge page) is treated as transient: absorbed inside the retry window, and passed through as a retryable 503 when it outlasts the window, because a bare 403 classifies terminal in Grok Build. A genuine origin 403 without Cloudflare markers is untouched.
- Non-streaming Chat Completions responses whose relay reuses one tool_call ID across calls are remapped to fresh unique IDs, matching the streaming rectifier's tolerance, instead of being rejected; the next round's tool history stays valid.
- Responses bodies that omit envelope bookkeeping (id, object, status) on an otherwise complete terminal payload get the missing markers synthesized instead of a 502 rejection; present-but-wrong values and a missing or malformed output remain rejections.
Added
- Regression coverage for wrapped-2xx absorb-then-recover and deterministic passthrough, Cloudflare challenge absorb/passthrough and origin-403 separation, envelope bookkeeping synthesis, and non-streaming duplicate call-ID remapping.
