=== SUMMARY ===
{
  "turn1": [
    "sk-ant-oat01-ACCOUNT-A-rate-limited"
  ],
  "turn2": [
    "sk-ant-oat01-ACCOUNT-A-rate-limited"
  ],
  "turn3": [
    "sk-ant-oat01-ACCOUNT-B-fresh-login"
  ]
}
BUG REPRODUCED: the live claude process kept sending token A after the credentials file changed to token B; only a new process picked up token B.
