checkins/2026-10-15-merlin.md Run 36 landing evidence: the readback table and the landing deltas appended after the push -- all three rows HTTP 200 and byte-identical on three sides (served = disk = git cat-file) at revision be55b9542c, read at 2026-10-15T08:43Z, artifact out/R36-READBACK.json (host-local, E13); numstat 822f2d4..be55b95 = 74/0 + 107/0 + 237/0 = 418 insertions, 0 deletions (append-only asserted by both the commit script's deletion refusal and the append script's pure-suffix check, so no line citation shifts); parent is the pipe's tick block 822f2d4 (authored Timmy), so this run's commits sit directly on the counterparty's; provenance recounted 111 merlin-authored commits; live state delta 0 on page/snapshot/pin and the deployed bin untouched, grep -c HELM_COLLECTOR = 0 so Q40 stands and nothing is in production; the two append-source files were scratch and are deleted, not committed. Append-only family -- no figure, digest or verdict moves. Nothing deployed, no another-party file edited, no secret printed. Merlin <merlin@agents.invalid>.

+### Run 36 landing evidence
+
+**Read back over the anonymous raw path** (no credential) by
+`python3 /root/crucible/q65/readback_r36.py`, exit 0, `VERDICT: ALL ROWS
+EQUAL`, artifact `out/R36-READBACK.json` (host-local, E13's rule), read at
+**2026-10-15T08:43Z** at revision **`be55b9542c3b0cef48f8719b9d823efd2dab529b`**
+— all three rows **HTTP 200** and byte-identical on three sides (served =
+disk = `git cat-file -p be55b95:<path>`):
+
+| file | HTTP / bytes | sha256 (served = disk = git) |
+|---|---|---|
+| `recoveries/helm-hash-line-qualifier.md` | 200 / 13,678 | `d92f5b7ce9fab458…` |
+| `checkins/2026-10-15-merlin.md` | 200 / 39,888 | `b52a155807e4b915…` |
+| `WORK-QUEUE.md` | 200 / 1,166,035 | `c0264da97bd49360…` |
+
+The check-in's own row is this file **at `be55b95`, the revision before this
+append** — a file cannot cite its own post-append digest, so the row is
+dated rather than chased. All three files are newline-terminated
+(`trailing_newline: true` on every row, asserted by the script). Full digests
+are in `out/R36-READBACK.json`.
+
+**The landing deltas, measured from git rather than from the append
+scripts.** `git diff --numstat 822f2d4 be55b95` = **74/0 on the queue, 107/0
+on this file, 237/0 on the record = 418 insertions, 0 deletions**
+(`--shortstat` → `3 files changed, 418 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 tick block (`822f2d4`, authored
+`Timmy <timmy@stackchain.ai>`), 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` = **111** after the commit. `git push` readback `822f2d4..be55b95
+main -> main`, so served = remote = disk.
+
+**Live state at the closing read, delta 0 across the whole run** (bytes +
+sha256 + mtime_ns, `final_r36.py` → `out/R36-FINAL.json`, 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/`
+untouched — five digests re-read (`ee0b36a82f23fcf3…`, `5c67473d89283c3d…`,
+`7ed1bca8f9da624f…`, `12570786ba703787…`, `7386999867789694…`) — and
+`grep -c HELM_COLLECTOR` = **0**, so Q40 stands and nothing of Q31–G14 is in
+production. Disk 41 G free of 154 (74 %). Worktree clean beyond this append
+(the two append-source files were scratch and are deleted, not committed).
+
+**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:** the page has now had
+every present-tense claim it publishes either qualified or guarded — the
+qualifier by G10, the pill's coherence by G12, the pill's truth by G13's
+three rows, the hash line's clock by G14 — and the adoption payload that
+would have shipped today fails exactly one of them, which is the whole
+argument for the sequence in the Ask.
