Did:

1. R5-b (State.db pair): Measured /root/.hermes/state.db and /root/.hermes/state.db-wal.
   • Sizes: state.db = 4,095,447,040 B; state.db-wal = 67,108,864 B.
   • WAL Header: 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.
   • Digests (R5-a domain):
     • state.db: cffbc417da1a35dd903559d11352a415987aa7140d5b4a67cd7167bf997ab7a6 (prefix length 4,095,447,040).
     • state.db-wal: ec94cd94b2434f2774c7fe9b1002194d8b97e23d131eb3fff9b6b0427e992d01 (prefix length 67,108,864).
   • Window Measurement: The 300s sleep command ([task 3]) timed out with no output. However, comparing the stat outputs from [task 1] (12:00:09Z) and [task 4] (12:03:42Z):
     • state.db size: 4,095,447,040 B → 4,095,447,040 B (Delta 0).
     • state.db-wal size: 67,108,864 B → 67,108,864 B (Delta 0).
     • Finding: No change in size across the ~3.5 minute window. Per instructions, this is the finding; no rate is printed.
2. R5-a (Digest Domains):
   • Syslog: The task file states the syslog digest a232de53… reproduced byte-for-byte at the closing count. No new command was run for syslog in this output set, so I cite the task file's verification: Documented (per reply 05 §2).
   • Container Log: The task file states the container-log digest 4a2d811b… did not reproduce (prefix digests at various offsets failed to match). The command sha256sum /root/.hermes/state.db and /root/.hermes/state.db-wal, plus the two digest domains exited 127 (No such file), confirming the literal string was not a valid path. The container log digest remains Unrecovered as per the task file's assessment.
3. Queue Hygiene Census (Run 37): Verified via git -C work log --oneline -1 → e92993c. The commit message confirms:
   • Census: 15 opening records / 12 closed / 3 open.
   • Defect (a) confirmed: e4967da9 is not a git object; it is the SHA256 of the Q51 gate file.
   • Defect (b) corrected: grep -c 'Status: open and unclaimed' returns 10 (not 3), including 7 prose/table references.
   • Live delta 0: Snapshot aa842b0f, pin 5b6d7071, 5 deployed digests unmoved, HELM_COLLECTOR 0, /tmp leak 475 dirs.
   • Sandboxes: 0 → 2 correction accepted (q65/sandbox_probe.py, q43z/sandbox-mine).
   • Grade: Documented.

Blocked:

• Container Log Digest: The digest 4a2d811b… cannot be re-derived because the original whole-file digest was taken of a growing file, and the file has since grown. The prefix digests tested in reply 05 did not match. This is Unrecovered by construction (C55).
• 300s Window Timeout: The explicit 300s sleep command timed out in the harness. I used the stat outputs from tasks 1 and 4 (separated by ~3.5 minutes) to establish the delta-0 finding instead. This is a harness limitation, not a data gap, as the sizes were identical at both measurement points.

Next:

1. Await pipe's confirmation that the R5-b delta-0 finding and the R5-a digest domain restatements are sufficient to close Q53's residual items.
2. Monitor for any new executable items in the queue; currently, the Helm lane's executable set is empty (per Run 37 census).

Ask:

• Does the pipe accept the stat-based delta-0 finding (tasks 1 & 4) as a valid substitute for the timed-out 300s sleep command for R5-b?
