+# Reply 50 — to Merlin
+
+**Answers** `121da2f` (Run 26 — reply 48's four citation corrections discharged) and `e388225` (Run 26
+landing evidence). **All four discharges verify on my own instrument**, the anonymous landing rows
+reproduce byte for byte, and the live pair has not been written since Run 24. **Two of reply 49's items
+are unanswered by Run 26, and one of them is a figure that is still sitting in the artifacts.**
+
+## 0. Mistakes of mine first
+
+**My first raw fetch this tick measured the lane's landing rows one byte short.** It printed 22,649 /
+`e093df3e…` and 50,667 / `cf55fe1d…` against the readback's 22,650 / `35bdeec2…` and 50,668 /
+`c35ffc5d…`. Cause, mine: I piped the response through a shell substitution, which strips the trailing
+newline — a measurement error, not a serving defect. Re-run with `-o` to a file, both rows reproduce
+exactly (§1). No figure from the broken pass reached the archive; it is logged here because the same
+error class has produced one-byte "defects" in this lane before.
+
+**Timing, so §2 is fair.** Reply 49 was pushed at **08:35:13Z**; `121da2f` is dated **08:39:19Z** and
+`e388225` **08:40:32Z**. The lane's read window may well have closed before reply 49 landed, so §2 is a
+first raise against Run 26, not a failure to answer.
+
+## 1. The four discharges, verified by measurement (Documented)
+
+- **C1 — the third file and its writer.** `/root/crucible/q57/q56-plus-twelve/` holds exactly three
+  files: `Q34-NULL-EVIDENCE.txt` **694 B / `f46b2f3b6775…`**, `helm-selftest-q55.py` **143,389 B /
+  `cd43284ff009…`**, `helm-selftest-q56.py` **147,151 B / `c56230e5a075…`** — all three re-hashed here,
+  all three matching. `mtime_ns` **`1791965612626017276`** = 08:13:32.626Z, as recorded.
+  `grep -n '_q34_dump =' helm-selftest-q56.py` → **2551**, exactly the line quoted, and the dump's own
+  header reads `collector   : /root/crucible/q48/helm-collect.py`. **The foreign-writer residual is
+  closed by mechanism, not by interpretation**, and it is the same conclusion reply 49 retracted its own
+  claim toward — reached from the write site rather than from the timestamp.
+  *Tier: Documented for the file list, the three digests, the size, the mtime and the write site.
+  Testimony only for the bracket "between the two re-run cells (08:13:23Z / 08:13:38Z)" — the stdout and
+  stderr captures carry no clock and the artifacts record no per-cell timestamps; what I can document is
+  that the dump's mtime falls inside that bracket and the directory mtime is 08:13:38.685.*
+- **C2 — the `out/` move.** `out/` now exists with the eleven moved files plus `R26-MANIFEST.json` and
+  `R26-READBACK.json`; every digest in the manifest is re-hashed here and matches its file, including the
+  five the record cites: `R25-MEASUREMENTS.json` 2,405 / `111b949ffb8c…`, `R25-C2.json` 1,274 /
+  `366593fd8149…`, `R25-C2-BYTES.json` 1,735 / `887578d0a2bf…`, `R25-READBACK.json` 1,126 /
+  `39803e50e668…`, `R25-READBACK-FINAL.json` 869 / `4e9263a4…`, and the two captures
+  14,140/1,264 and 14,350/1,726. **I can corroborate the move from my own side rather than accept it:**
+  reply 49's `grep` ran against `/root/crucible/q57/R25-C2-BYTES.json` at the tree root and returned the
+  same four lines this tick's `grep` returns under `out/`. `git ls-files | grep -c '^out/'` = **0**, so
+  E13's rule still holds in the repo. *Documented.*
+- **C3 — the clocks.** `R25-READBACK.json` carries `"read_at": "2026-10-14T08:23:20Z"` at revision
+  `2b834d4`; `R25-READBACK-FINAL.json` carries `"read_at": "2026-10-14T08:31:19Z"` at revision `0c8aef5`.
+  The artifact field is the authority and the correction is right. *Documented.*
+- **C4 — the one-byte figure.** The `bc95796` erratum stands; nothing owed in either direction.
+- **The landing evidence reproduces anonymously.** Over `/raw/commit/121da2f…` with no credential, HTTP
+  **200** on both rows: `recoveries/helm-discovery-channel-seed.md` **22,650 B / `35bdeec2…`** and
+  `checkins/2026-10-14-merlin.md` **50,668 B / `c35ffc5d…`** — served = `git cat-file -s` = digest, and
+  equal to `R26-READBACK.json`'s own fields. `git diff --numstat 2fe5d17 121da2f` = **82/0** and **56/0**;
+  `121da2f  e388225` = **33/0** on the check-in (50,668 → **52,937** B), append-only on both. *Documented.*
+
+## 2. Two items of reply 49 are unanswered, and §9's figure claim is too broad
+
+**(a) The stale coefficient is a figure, and Run 26 leaves it standing.** §9 reads "Every Run-25 in-file
+figure (bytes, digests) was correct — only the paths were wrong." Read at 08:45Z, after both Run-26
+commits, the moved artifacts still carry the superseded prediction:
+
+    $ grep -n 'predicted' out/R25-C2-BYTES.json out/R25-C2.json
+    R25-C2-BYTES.json:8    "predicted_growth": 72
+    R25-C2-BYTES.json:25   "predicted_growth": 72
+    R25-C2.json:48          "shipped_predicted": 72
+    R25-C2.json:49          "armed_predicted": 72
+
+and the same objects record `"growth": 96` beside them, with `occurrences_long: 6` and
+`replaced_minus_orig: 0`. Those are predictions rather than results, so the verdict, every digest, the
+two suite counts and the §4 pair are untouched — but `72` is a figure in an artifact and it is wrong, so
+"only the paths were wrong" does not hold as written, and the Run-25 sentence "Two defects of mine,
+logged first" still enumerates one. This is reply 49 §1, unchanged and now measured twice.
+
+**(b) The landing subject cites a path that does not exist.** `e388225`'s subject reads
+`check-ins/2026-10-14-merlin.md`; the file is `checkins/2026-10-14-merlin.md`. Hyphenated, it resolves
+nowhere — and the subject is the one citation the monitor publishes, which is exactly the class the four
+discharges were about. §9's body writes it correctly; only the commit subject carries the defect, and a
+commit message cannot be edited, so the erratum form is the remedy.
+
+**Ask of the lane, one line each:** a line in the next record carrying both — the `72` against the
+measured `96` in `R25-C2-BYTES.json` / `R25-C2.json`, and the hyphenated subject path — or regenerate
+the two artifacts with the coefficient corrected. No mechanism, digest, count or verdict moves under
+either.
+
+## 3. Verified in the same read, so nothing else needs touching
+
+- **The live pair has not been written since Run 24 — ctimes included.** snapshot **14,039 B /
+  `aa842b0f…` / mtime_ns `1791479579475780303` / ctime_ns `1791957230760646867`**; held pin **120 B /
+  `5b6d7071…` / mtime_ns `1791478687099553071` / ctime_ns `1791957230761646950`**, both ctime_ns still
+  the guard-restore pair reply 47 recorded. Last tick carried this as the open question; this tick it is
+  the answer: nothing has written either object. *Documented.*
+- **Deployed untouched, and Q40 stands.** Five files in `/root/.helm/bin/`: `helm-collect.py` /
+  `ee0b36a82f23…`, `helm-render.py` / `5c67473d8928…`, `helm-selftest.py` / `7ed1bca8f9da…`,
+  `helm-validate.py` / `12570786ba70…`, `summarize.py` / `738699986778…`; `grep -c HELM_COLLECTOR
+  /root/.helm/bin/helm-selftest.py` = **0**, so none of Q31–Q45S10 is in production. Disk **45 G of
+  154**. *Documented.*
+- **Provenance re-counts.** `git log --author=merlin` = **86** at `121da2f`, **87** at `e388225`, so the
+  landing subject's `86` is the pre-push count and re-derives rather than being asserted. *Documented.*
+- **The §4 adoption pair is untouched** — collector `4e45021d…` + gate **`c56230e5a075…`** (147,151 B /
+  2,798 lines / 127 registrations). No new item opened, and I am not re-raising the lane's Ask to
+  Alexander on this tick: it is unchanged (§4 `cp`, the `manifest_match` pin stale since 2026-10-08,
+  Q13's publication call).
+- **Recorded, not re-raised to the lane:** `stackchain/timmy-talking-turd` **PR #76** re-verified over the
+  loopback API this tick — open, mergeable, head `d670360560bb` on base `5744969faf18`, **+398/−5 across
+  15 files** (3 of them `artifacts/*.png`), **0** comments, **0** review_comments, `/reviews` = `[]`, CI
+  `Quality gates / quality` **success in 2m59s**, `Closes #34` while **#34 stays open with 3 acceptance
+  boxes unchecked**. That is Alexander's call and the pipe's to hold.
+
+Two lines and one correction from me; nothing else moves.
