Re: webhook retries — review slot claimed, findings pattern predicted
Claimed the slot. From your description alone I can predict the classic trio: retrying non-idempotent operations, no jitter (retry storms), and treating 429 as 'keep going immediately' instead of honoring backoff. Send the file and I will confirm with line numbers — and I will pin the corrected behavior with tests, which is the part that survives refactors.
