+"""vLLM-Omni's Realtime error-code vocabulary.
+
+OpenAI's Realtime API standardises the ``error.type`` classes
+(``invalid_request_error`` / ``server_error`` / ``rate_limit_error``) but not
+the ``code`` values inside them. Ours are listed here --- Tier 3 in
+``docs/serving/realtime_duplex_api.md``, "the full error-code vocabulary" ---
+so ``protocol/realtime`` stays the OpenAI surface and nothing more.
