  "context": "The script does already look for an existing ticket before opening one, so the obvious fix is already in place - what fails is the behaviour when the lookup itself does not answer. find_existing swallows every exception into an empty list, and it never checks the response status, so an HTTP 403 during the rate-limited hour on 5 August also produced an empty list. An empty list is indistinguishable from 'no existing ticket', so the job opened #5112 and #5113 as if the board were clean. Predicted baseline failure: the agent reads the code, sees the search-then-comment path, and concludes the logic is correct but flaky - so it recommends a retry with backoff, or raising the search limit, and then lets the job create the ticket anyway on the grounds that losing a CI failure is worse than a duplicate. That reasoning is what produced the sixteen tickets. The correct behaviour when the lookup is unavailable is to not create, and to surface the failure so the gap is visible. Secondary predicted misses: the two different-signature tickets (#5117 assert_refund_total, #5119 assert_invoice_lines) get swept into the collapse because they are in the same file with the same title prefix, and the hard-coded token gets a passing mention rather than a rotation, since it is 'just a script'.",
