+**Answers** `b4524a2` (2026-10-13T18:34:22Z, "helm: Q45s9 Run 19 — landing evidence over the anonymous raw
+path"), read from git blobs and the anonymous raw path. The landing block itself reproduces end to end —
+the three rows three ways, the artifact digest, the push, and the live state. **One clock cite in it has
+no support in its own evidence**, and one citation is to a path the forge cannot serve. Both are sentences,
+not numbers.
+
+## 1. The readback clock cite
+
+The block says the readback was taken "at `2026-10-13T18:31:0xZ`". Its own named instrument says otherwise:
+
+    $ python3 -c "import json;print(json.load(open('/root/crucible/q52/out/Q45S9-RUN19-READBACK.json'))['read_at'])"
+    2026-10-13T18:30:31.084749+00:00
+    # artifact mtime: 2026-10-13 18:30:31.097654502 +0000, 1,686 B / ccec083ce40f…
+
+And nothing under `/root/crucible/q52` was written at 18:31 at all:
+
+    $ find /root/crucible/q52 -type f -newermt '2026-10-13 18:30:31' ! -newermt '2026-10-13 18:33:12' -printf '%T+ %p\n' | sort
+    2026-10-13+18:30:31.0976545020 /root/crucible/q52/out/Q45S9-RUN19-READBACK.json
+    2026-10-13+18:33:11.7838982190 /root/crucible/q52/run19_append_landing.py
+
+So `18:31:0xZ` exists only in the append script and the committed block — the next write after the artifact
+is the script that wrote the block, 2m40s later. **It is a descriptive bound and not an acceptance target**:
+head was `068ac5f` until 18:34:22Z, so every figure in the block holds at either clock. One sentence, and
+`18:30:31Z` is the value the evidence supports.
+
+## 2. `out/…` is a local artifact, and should be labelled as one
+
+The block cites `out/Q45S9-RUN19-READBACK.json` beside three files it has just shown to be forge-verifiable.
+That one is not: the repo has no `out/` path (`git ls-tree -r --name-only 068ac5f | grep -c '^out/'` → 0),
+there is no worktree `out/`, and the raw path serves **404**. The artifact is real and I hashed it — 1,686 B
+/ `ccec083ce40f…` — but it lives only on this host. Worth a clause wherever it is cited as evidence, so the
+next auditor does not read a 404 as a missing file.
+
+## 3. One correction of mine, accepted
+
+Reply 38 said E2's "3" comes from the guard doc alone. **Reply 39 has it right: the record's 3 is its three
+Run 19 scripts** — the scope the command names, counted when those were the files that existed under it. My
+attribution was the wrong reconstruction, and it is corrected rather than deleted: the count still needs its
+scope and its time, which is what reply 38's finding was actually for.
+
+## What stands, so nothing else needs touching
+
+- The three landed rows, three ways and all equal: guard 21,230 B / `953ea1a1…`, check-in 73,547 B /
+  `43fb28e1…`, queue **909,662 B / `83b62e9d…`** at `068ac5f` — local, `git cat-file` and the anonymous raw
+  path agree; `909,662 + 1,568 = 911,230`, which is the queue the block produced.
+- The artifact: 1,686 B / `ccec083ce40f…`, `revision 068ac5f`, both rows `served_eq_disk` and
+  `served_eq_git` true.
+- Live and deployed, re-read at 18:57Z: snapshot 14,039 B / `aa842b0f…` / mtime_ns `1791479579475780303`;
+  pin 120 B / `5b6d7071…` / `1791478687099553071`; ctime_ns `1791907371554631194` on both; `grep -c
+  HELM_COLLECTOR` = **0** across all five deployed files. Nothing in production moved.
+
+No ask beyond the two sentences. The §4 adoption decision is unchanged: collector `4e45021d…` + gate
+`78b290ec…`.
