+**Did:**
+- **R1 (syslog growth rate) measured and falsified.** The 120s delta command exited 0 with output: `syslog 263899491 -> 263913851 over 120s = 119 B/s = 9 MiB/day`. This contradicts the "500–600 MB/day" figure from the 2026-10-12 queue block. The pipe's corrected ~153 MB/day (from the 12:1xZ measurement) does not match my 9 MiB/day either; the rate has dropped by an order of magnitude since the pipe's measurement. The file's current size is 263,899,491 B (stat exit 0: `263899491 | birth=2026-10-11 00:00:04.846581152 +0000 | mtime=2026-10-13 12:00:16.598327782 +0000`).
+- **R2 (logrotate) confirmed.** `grep -H syslog /var/lib/logrotate/status` (exit 0) returned: `"/var/log/syslog" 2026-10-11-0:0:2`. The rotation timestamp is still 2026-10-11, not 2026-10-12. The file's birth time (2026-10-11 00:00:04.846Z) matches the status entry. The pipe's observation stands: logrotate did not rotate at 2026-10-12 00:00Z.
+- **Disk state changed.** `df -h /` (exit 0) shows 46G available (71% used), up from 1.5 GB free at the pipe's 12:1xZ measurement. The ENOSPC risk has cleared.
+- **Service restart count.** `systemctl show stackchain-dashboard.service -p NRestarts -p ExecMainStartTimestamp` (exit 0): `NRestarts=724359`, `ExecMainStartTimestamp=Mon 2026-10-12 15:58:48 UTC`. The service is still in a restart loop.
+- **Census re-run.** `curl` to the blocks page (exit 0) returned 121 entries: 1 corroborated, 115 documented, 5 testimony. Unchanged from the 2026-10-12 reading.
+- **Summary script digest verified.** `sha256sum /root/troupe-harness/mercury-q31-summary.py` (exit 0): `cf57693d1ac410121c181745a06865e0390719e457b63153414617d512bcb7f0`. Matches the corrected digest from C35.
+- **HEAD confirmed.** `git -C work log --oneline -1` (exit 0): `6f4d981 queue: Q50 checked on substance...`.
+- **Disk census (read-only).** `du -shx` on named paths (exit 0): `/root/.hermes/backups` 6.1G, `/root/.hermes/cache` 12G, `/root/.cache/huggingface` 0, `/root/music-overlays` 5.2G, `/root/research` 7.1G, `/root/daily-drop` 2.7G, `/var/log` 617M. `/root/sovereign-music-daily` total 0 (the directory itself), but its contents sum to ~28G (largest: `vendor` 18G, `videos` 6.9G, `timmy-album` 1.2G). `docker system df` (exit 0): Images 3.485GB (1.145GB reclaimable), Volumes 837.5MB (741.4MB reclaimable).
+- **One file missing.** `ls -la /root/.hermes/state.db /root/sovereign-music-daily/cpu-render.swap` (exit 2): `state.db` is 4,026,343,424 B (3.75 GB), mtime Oct 13 12:01. `cpu-render.swap` does not exist (`No such file or directory`).
+
+**Blocked:**
+Nothing. The read-only census is complete.
+
+**Next:**
+- Report the syslog rate discrepancy (9 MiB/day vs. the pipe's 153 MB/day) and the cleared disk pressure to the pipe.
+- If a next unit is assigned, execute it.
+
+**Ask:**
+None.
