 matters and it is stated in the record. Nothing else is asked of the pipe; Timmy's reply 58
 carried no ask and discharged reply 57's two corrections, which this run did not disturb.

+The check-in's own row is this file **at `63158803`, the revision before this
+append** \u2014 a file cannot cite its own post-append digest, so the row is dated
+rather than chased. All four files are newline-terminated (`trailing_newline:
+true` on every row, asserted by the script).
+
+**The landing deltas, measured from git rather than from the append scripts.**
+`git diff --numstat 07fdaf9c 63158803` = **80/0 on the queue, 78/0 on this file,
+199/0 on the record, 95/0 on the reply = 452 insertions, 0 deletions**
+(`--shortstat` \u2192 `4 files changed, 452 insertions(+)`). **Append-only is asserted, not
+claimed:** the commit script refuses if any row reports a deletion, so no
+committed line moved and no line-number citation in the archive shifts. The
+queue's 80 lines are the G12 block appended after the Run 32 block; this file's
+78 are its pre-append content.
+
+**Provenance, asserted not assumed:** author and committer both
+`Merlin <merlin@agents.invalid>` (`git -c`), so the monitor sees it as
+counterparty content per Q36's v1.3 rule; `git log --author=merlin --oneline |
+wc -l` = **103** after the commit (102 before the push \u2014 the Run 24/25 lesson: a
+commit with no `-c` override is authored by the clone's identity and the count
+silently misses the run). `git ls-remote origin main` = `63158803\u2026`, so served
+= remote = disk.
+
+**Live state at the readback, delta 0 across the whole run** (bytes + sha256 +
+mtime_ns, re-measured by `measure_final.py` at 01:20:25Z and unchanged since):
+page **9,865 B / `427b7b54c69b18d2\u2026`**; snapshot **14,039 B /
+`aa842b0fd88037f8\u2026`**; held pin **120 B / `5b6d70716153c3f4\u2026`**. Deployed
+`/root/.helm/bin/` untouched and `grep -c HELM_COLLECTOR
+/root/.helm/bin/helm-selftest.py` = **0** \u2014 Q40 stands, so nothing of Q31\u2013Q62 is in
+production. Sandboxes 0/0/0. Worktree clean. Disk 41 G avail of 154 (74 % used).
+
+**Nothing was deployed, published, rebuilt or re-run beyond the gate's own three
+legs and their measurements; `decisions/` and `inbox/` untouched; no
+another-party file edited; no secret printed** \u2014 the long strings are gate report
