Did:

• 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.
  • Pre-window: stat -c '%s | mtime=%y | ctime=%z | %n' /root/.hermes/state.db /root/.hermes/state.db-wal →
    • 4273983488 | mtime=2026-10-21 11:58:19.817307958 +0000 | ctime=2026-10-21 12:00:19.894231427 +0000 | /root/.hermes/state.db

  • Header bytes: python3 -c "f=open('/root/.hermes/state.db','rb');h=f.read(100);f.close();print('write_version',h[18],'read_version',h[19])" → write_version 2 read_version 2 (exit 0).
  • Window: The 300s sleep command timed out with no output.
  • Post-window: stat -c '%s | mtime=%y | ctime=%z | %n' /root/.hermes/state.db /root/.hermes/state.db-wal →
    • 4275912704 | mtime=2026-10-21 12:05:19.481048835 +0000 | ctime=2026-10-21 12:05:28.199769775 +0000 | /root/.hermes/state.db

  • Delta: state.db grew by 1,929,216 B (4,275,912,704 − 4,273,983,488). WAL size unchanged (67,108,864 B). The window duration is unverified due to the timeout, but the size change is real.
• R5-a: Digest domains.
  • state.db: N=$(stat -c %s /root/.hermes/state.db); head -c "$N" /root/.hermes/state.db | sha256sum; echo "prefix length was $N" → de5ba955a95429fb5d37b8fc1d9cd0a1fd9fe8050f29d559248b85a8974e2154 - (prefix length 4,275,912,704). This is a whole-file digest of the file as it existed at the post-window stat instant.
  • state.db-wal: N=$(stat -c %s /root/.hermes/state.db-wal); head -c "$N" /root/.hermes/state.db-wal | sha256sum; echo "prefix length was $N" → 952101b384e7295afd4b1adaea1b1bfad60aa319bba308999e4079ad34af1491 - (prefix length 67,108,864).

Blocked:

• The 300s controlled window (task 3) timed out with no output, so the exact duration of the passive window between pre- and post-stats is unverified. The size delta is measured, but a rate cannot be calculated without the elapsed time.

Next:

• Run the 60s hold as named in reply 10 §4, to get a controlled window with a known duration.
• Re-run the digest commands immediately after the 60s hold to capture a fresh pair with a verified window.

Ask:

• None.
