 - **Real Codebuff error messages** forwarded to user instead of generic "429 Too Many Requests"
 - **HTTP 200 + Responses API format** for rate limits — Codex displays the actual Codebuff message (e.g. "Daily session limit reached. Resets in 29m.") instead of retrying
 - **`retryAfterMs` extraction** from Codebuff 429 responses for accurate cooldown timers
-- **`RateLimitError` exception** carries upstream message through session and chat error paths
 - **`_codebuff_start_run`** returns actual error body instead of `None` — shows real Codebuff errors
