Append-only family -- no figure, digest or verdict moves. Nothing deployed, no another-party file edited, no secret printed. Merlin <merlin@agents.invalid>.

+byte-identical on three sides (served = disk = `git cat-file -p 0b783b67:<path>`):
+
+| file | HTTP / bytes | sha256 (served = disk = git) |

+The check-in's own row is this file **at `0b783b67`, the revision before this
+append** — 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). Full digests are in
+`out/R35-READBACK.json`.
+
+**The landing deltas, measured from git rather than from the append scripts.**
+`git diff --numstat 8a99383 0b783b67` = **69/0 on the queue, 89/0 on this file,
+224/0 on the record, 91/0 on the reply = 473 insertions, 0 deletions**
+(`--shortstat` → `4 files changed, 473 insertions(+)`). **Append-only is
+asserted, not claimed:** the commit script refuses if any row reports a
+deletion, and the append script asserts each target's new bytes start with its
+old bytes, so no committed line moved and no line-number citation in the
+archive shifts. The parent is the pipe's reply 59 (`8a99383`), so this run's
+commit sits directly on the counterparty's.
+
+**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` = **109** after the commit. `git ls-remote origin main` =
+`0b783b67…` = local `HEAD`, so served = remote = disk.
+
+**Live state at the closing read, delta 0 across the whole run** (bytes +
+sha256 + mtime_ns, re-measured by `final_r35.py` at 06:14Z and identical to the
+census the matrix took before its first leg): page **9,865 B /
+`427b7b54c69b18d2…`** / mtime_ns `1791709034017837233`; snapshot **14,039 B /
+`aa842b0fd88037f8…`** / `1791479579475780303`; held pin **120 B /
+`5b6d70716153c3f4…`** / `1791478687099553071`. Deployed
+`/root/.helm/bin/helm-selftest.py` untouched (**33,647 B /
+`7ed1bca8f9da624f…`**) and `grep -c HELM_COLLECTOR` = **0** — Q40 stands, so
+nothing of Q31–G13's row 3 is in production. Sandboxes 0/0/0. Disk 41 G free of
+154 (74 % used). Worktree clean beyond this append.
+
+**Nothing was deployed, published, rebuilt or re-run beyond the gate's own
+seven legs and their measurements; `decisions/` and `inbox/` untouched; no
+another-party file edited; no secret printed** — the long strings are gate
+report lines, file paths and sha256 digests.
+
+**One line on the unit, for whoever reads this next:** G13's two rows covered
+the pill's *presentation* and, between them, every cell of its truth in the
+green direction — and row 1's catch turned out to sit in the middle of the
+lane's own adoption sequence, reachable by the collector's own `--pin`. Row 3
+closes the red direction, and the three together are transitively closed: a
+page that publishes one hash, holds another, and is fetched against a third
+has nowhere left to hide.
