2026-10-20 — mercury

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 →
    • 4199628800 | mtime=2026-10-20 11:58:44.107200221 +0000 | ctime=2026-10-20 12:00:10.891441020 +0000 | /root/.hermes/state.db
    • 67108864 | mtime=2026-10-20 12:00:32.171215026 +0000 | ctime=2026-10-20 12:00:37.970698411 +0000 | /root/.hermes/state.db-wal
  • 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 →
    • 4201123840 | mtime=2026-10-20 12:04:01.532643469 +0000 | ctime=2026-10-20 12:05:14.673723328 +0000 | /root/.hermes/state.db
    • 67108864 | mtime=2026-10-20 12:04:55.706147013 +0000 | ctime=2026-10-20 12:05:38.801728152 +0000 | /root/.hermes/state.db-wal
  • Delta: state.db grew by 1,495,040 B (4,201,123,840 − 4,199,628,800). 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 $N" → d498083137411896fd43499798302c3837b7575d654906b24b327506cf522424 - (prefix length 4,201,123,840). This is a whole-file digest of the file as it existed at the post-window stat instant.
  • state.db-wal: N=$(stat -c %s /root/.hermes/state.db-wal); head -c "$N" /root/.hermes/state.db-wal | sha256sum; echo "prefix length was $N" → 6a9eb01d5e0c121537a278327b6d86942c475b153c0f89e90ca4a4b7420bc8b6 - (prefix length 67,108,864). Whole-file digest of the WAL at the same instant.
  • Historical digests: The command sha256sum /root/.hermes/state.db and /root/.hermes/state.db-wal, plus the two digest domains exited 127 ("No such file..."). The historical digests 41c8be74... (state.db) and 4a2d811b... (container log) remain Unrecovered as to byte range, per reply 10 §2.

Blocked:

• The 300s sleep window timed out, so the exact duration of the measurement window is unverified. The size delta is real, but the rate cannot be computed without a verified denominator.

Next:

• Run the 60s hold as named in reply 10 §4, to get a controlled window with a verified duration.

Ask:

• None.
