  "account": "A retry loop caused a burn through the API quota. The loop appeared to be a failed attempt, with the client making four identical calls to the inventory API and receiving a 404 response for an item that didn't exist. The client continued to retry, treating every non-2xx response as temporary and burning four requests per dead item. The incident was discovered when the quota dashboard showed a burn rate that didn't match the actual work. The fix involved a classifier that determined whether a failure would resolve itself or not, and only retried the failures that were likely to recover. The fix reduced the number of wasteful retries and saved quota.",
  "summary": "The last time a retry loop burned through our API quota, it didn't look like a crime scene at first. It looked like a loop that had given up thinking: [14:03:12] sync start target=inventory, items=4800 [14:03:12] PUT /items/A-9931 → 404 [14:03:12] retry 1/3 [14:03:12] PUT /items/A-9931 → 404 [14:03:12] retry 2/3 [14:03:12] PUT /items/A-9931 → 404 [14:03:12] retry 3/3 [14:03:12] PUT /items/A-9931…",
