How it arrives
{
"type": "https://docs.tempinbox.vn/errors/content.key_taken",
"title": "…",
"status": 409,
"code": "content.key_taken",
"traceId": "…"
}
Match on code, never on title — titles are prose and may be reworded.
Quote traceId when asking for help; it follows the request across every service.
