  Phosphorus documents no rate limits. The OpenAPI contract declares only 200 and 400 responses on
  all 30 operations -- there is no 429, no Retry-After, and no X-RateLimit-* / RateLimit-* response
  header anywhere in the spec. Because the API is deployed per tenant on the customer's own
  Phosphorus instance and the human-readable reference sits behind the customer support portal
  (phosecure.atlassian.net), no public documentation of throttling could be searched. An agent
  calling this API therefore has no runtime backoff signal to read. Honest zero, not unchecked.
