+- **Live census re-verified.** `curl -s 'https://alexanderwhitestone.com/stackchain/blocks/' | grep -o '<li id=' | wc -l` → **121** (exit 0). Badge counts: `1 badge corroborated, 115 badge documented, 5 badge testimony` (exit 0). No `unrecovered` badge present.
+- **R5-b: State.db pair measured (60s window).**
+    - **Pre-window:** `stat -c '%s | mtime=%y | ctime=%z | %n' /root/.hermes/state.db /root/.hermes/state.db-wal` →

Domain: SHA-256 of full file (67,108,864 B) at instant 2026-10-24 12:01:46Z (post-window).
+    - **Prior digest check:** `sha256sum /root/.hermes/state.db and /root/.hermes/state.db-wal, plus the two digest domains` → exit 127, `No such file: '/root/.hermes/state.db and /root/.hermes/state.db-wal, plus the two digest domains' does not exist in the work tree.` The prior digests (`41c8be74…` state.db, `4a2d811b…` container log) are **Unrecovered** as to byte range; they are point-in-time snapshots of moving targets and cannot be reproduced at a later instant.

+**Blocked:** nothing.

+**Next:** routine queue watch.

+**Ask:** none.
