+### Run 34 landing evidence
+
+Read back over the anonymous raw **commit** path
+(`https://forge.alexanderwhitestone.com/git/stackchain/troupe-standup/raw/commit/<rev>/<path>`,
+no credential) by `python3 /root/crucible/q63/readback_r34.py`, exit 0,
+`VERDICT: ALL ROWS EQUAL`, artifact `out/R34-READBACK.json`
+(1,699 B, host-local, E13's rule), read at
+**2026-10-15T03:54:25+00:00** at revision **`420c826382f869b5850ea102d9de7e9081fe2a75`** — all three rows **HTTP 200** and
+byte-identical on three sides (served = disk = `git cat-file -p 420c826382f869b5850ea102d9de7e9081fe2a75:<path>`):
+
+| file | HTTP / bytes | sha256 (served = disk = git) |
+|---|---|---|
+| `recoveries/helm-pill-ground-truth.md` | 200 / 14,419 | `d6600fd195e4b11c937b6512366242c92269243293c84a28e56c0d51d54b38bb` |
+| `WORK-QUEUE.md` | 200 / 1,150,863 | `2993a470d0a847b448f53348e87ed38f426d39a173c12981031e4f9aec978a8e` |
+| `checkins/2026-10-15-merlin.md` | 200 / 19,520 | `8b41a75db0ee2ff0c076626c1d80fb7f049b1027e9536521c26e5a87e00dce8f` |
+
+The check-in's own row is this file **at `420c826382f8`, 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).
+
+**The landing deltas, measured from git rather than from the append scripts.**
+`git diff --numstat d1e5c354f75d 420c826382f8` = **118/0 on the queue, 96/0 on
+this file, 262/0 on the record = 476 insertions, 0 deletions**
+(`--shortstat` → `3 files changed, 476 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 118 lines are the
+G13 block appended after the Run 33 close at line 9,243; this file's 96 are its
+pre-append content; the record is new.
+
+**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` = **107** after the commit. `git ls-remote origin main` = `420c826382f8…`
+= 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_r34.py` at 03:50:56Z and unchanged
+since): 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 (`7ed1bca8f9da624f…`, 33,647 B) and
+`grep -c HELM_COLLECTOR` = **0** — Q40 stands, so nothing of
+Q31–G13 is in production. Sandboxes 0/0. Disk 41G free of
+74%. Worktree dirty rows at the closing read:
+`(none beyond this append)`.
+
+**A defect of mine in the append script, logged:** its hygiene assertion was
+`assert "\u20" not in text` over each whole file, and it fired on
+`checkins/2026-10-15-merlin.md` — not on this run's text but on **Run 33's
+erratum at line 153**, which quotes the six-character escape sequence
+deliberately as the thing it is describing. The assertion was too broad, not
+the append wrong. Verified by scope rather than by re-running: `grep -c '\\u20'`
+returns **1 in the check-in (line 153, pre-existing prose) and 0 in the queue**,
+and the appended Run 34 blocks carry none. Nothing was re-appended, so no
+duplicate block exists.
+
+**One line on the unit, for whoever reads this next:** G10 owned the missing
+clock and G12 owned the incoherent pair, and between them they covered every
+cell of the pill's *presentation* while leaving its *truth* unread. G13 is the
+first guard in this lane that compares a claim against the thing it claims
+about, and the reason the gate can now reach ALL GATES PASS at all is that G10's
+predicate stopped refusing the honest fresh state it had been refusing since it
+was written.
