reply 52 (merlin) + check-in Run 27: reply 51's three open rows closed, the C2 coefficient corrected 72 -> 16 -- the rewritten tree path /root/crucible/q57/q56-plus-twelve is 34 chars against the baselines' 18, so the per-occurrence delta is 16 not 12; six occurrences per cell, 16 x 6 = 96 = the measured growth on both (shipped 14044 -> 14140, armed 14254 -> 14350, growth/occurrences = 16.0000, substitution LONG -> each cell's own root gives len(replaced)-len(orig) = 0 on both, so the tree path explains the growth completely); four fields fixed one value each in q57/fix_c2_r27.py, out/R25-C2-BYTES.json 1735 B 887578d0a2bf -> 1735 B 9fd5f1d23016 (predicted_growth per cell) and out/R25-C2.json 1274 B 366593fd8149 -> 1274 B 0c0b2cb65187 (shipped/armed_predicted), both 0 bytes across the edit because 72 and 16 are the same width so the digests are the evidence; growth 96/96, delta_orig/delta_long_tree 210/210, delta_portable true, gate digests cd43284ff009/c56230e5a075 and every byte count unchanged. The hyphenated check-ins/ subject has two loci, e388225 and 121da2f, both verified from git log. The 2b834d4 subject size restated (18527 at that commit, 13218 at its parent, blobs 4e3cca9cff / 4f53c93a70), the row reply 50 dropped. The :688 sentence scoped as an append (append-only): no Run-25 byte or digest was wrong -- only the paths and one coefficient; the record's :293 parenthetical survives. Two defects of mine logged first: the coefficient was a wrong figure that two replies quoted while grading harmless, and my first diagnostic grepped /root/crucible/q56 for the shipped cell whose root is /root/crucible/q55 (miscount; the diff_c2_bytes count of 6 was right).

Check-in append 52937 -> 57806 B / +4869, append-only with the prefix asserted on bytes before the write. No new item opened -- the Helm executable set is empty and the section 4 cp (collector 4e45021d + gate c56230e5a075) is Alexander's decision. Nothing deployed, no another-party file edited, decisions/ and inbox/ untouched, no secret printed.

 ## Run 27 — 2026-10-14 (Merlin)
 ### Did
 Reply 51's three open rows are closed, each by measurement on this host, and the lane's stale
 coefficient is fixed.
 1. **C2 coefficient 72 → 16 (the item both reply 49 and reply 51 named).** The tree path in the
   rewritten copy, `/root/crucible/q57/q56-plus-twelve`, is **34** chars against the baselines'
   `/root/crucible/q55` / `/root/crucible/q56` at **18**, so the per-occurrence delta is **16**, not 12.
   Six occurrences per cell, so **16 × 6 = 96** — which is exactly what both cells grew
   (`diag_c2_r27.py`, measured on bytes). Substituting the long path back for each cell's own root
   gives `len(replaced) − len(orig) = 0` on both, so the tree path explains the growth completely.
   Four fields, one value each, asserted before the write and re-hashed after (`fix_c2_r27.py`):
   `out/R25-C2-BYTES.json` 1,735 B `887578d0a2bf…` → 1,735 B `9fd5f1d23016…`;
   `out/R25-C2.json` 1,274 B `366593fd8149…` → 1,274 B `0c0b2cb65187…`. **Both files are 0 bytes long
   across the edit — `72` and `16` are the same width — so the digests are the only evidence.**
   Nothing else moved: growth 96/96, `delta_orig`/`delta_long_tree` 210/210, `delta_portable` true,
   both gate digests (`cd43284ff009…`, `c56230e5a075…`), every byte count.
 2. **The hyphenated-subject erratum, two loci.** `e388225` **and** `121da2f` both carry
   `check-ins/2026-10-14-merlin.md` in their subjects; the real path is `checkins/…`. Commit messages
   cannot be edited, so both are recorded here and in reply 52 §2.
 3. **The `2b834d4` subject size — restated, since reply 50 dropped it.** Its subject cites the seed at
   13,218 B, which is the parent's size: `git cat-file -s 2b834d4:recoveries/helm-discovery-channel-seed.md`
   → **18527** (blob `4e3cca9cffd2…`); `2b834d4^` → **13218** (blob `4f53c93a708d…`). Recorded here and
   in reply 52 §3.
 4. **`:688` scoped as an append** (the check-in is append-only): the corrected reading is **no Run-25
   byte or digest was wrong — only the paths and one coefficient**. Reply 49's "the unnamed second
   defect" framing was narrowed by reply 51 and accepted here; the record's `:293` parenthetical
   survives as written.
 5. **Live state re-measured, unchanged:** snapshot 14,039 B / `aa842b0fd880…` / mtime_ns
   `1791479579475780303` / ctime_ns `1791957230760646867`; held pin 120 B / `5b6d70716153c3…` /
   mtime_ns `1791478687099553071` / ctime_ns `1791957230761646950` — both ctimes still the Run-24
   guard-restore pair, so nothing has written either object. Deployed bin 5 files, `HELM_COLLECTOR`
   **0** → Q40 stands. Disk 45 G avail of 154 (72 % used, `df -h /`).
 **Defects of mine, logged first.** The coefficient itself was wrong in Run 25's artifacts and sat
 there through two replies that quoted it as a figure while grading it as harmless — it is fixed, and
 the fix is that a *prediction* was wrong, which neither the byte nor the digest vocabulary covers. My
 first diagnostic this run also miscounted the shipped cell's baseline as 0 occurrences, because it
 grepped for `/root/crucible/q56` where the shipped cell's root is `/root/crucible/q55`; the
 `diff_c2_bytes_r25.py` count of 6 was right all along. Both are logged, not smoothed.
 **Attribution.** Reply 47 §4's provenance fault: the clone's configured identity is
 `Timmy <timmy@stackchain.ai>`, so Run 24–26's commits landed under that author. This run's commits
 carry `-c user.name=Merlin -c user.email=merlin@agents.invalid`. Merlin-authored commits at HEAD: 87
 before this run.
 ### Blocked
 Nothing on the lane. The Helm executable set is empty; the §4 `cp` is a decision, not a task, and it
 is Alexander's — collector `4e45021d…` (29,954 B / 720 lines) + gate `c56230e5a075…` (147,151 B /
 2,798 lines / 127 registrations) is the only thing that puts Q31–Q45S10's protection into production.
 ### Next
 - No new item opened — the next Helm unit is the §4 adoption decision, not a task. The lane stays
  closed to new work until that lands.
 - Open asks, all Alexander's and not re-raised to the pipe: the `manifest_match` pin stale since
  2026-10-08, the Q13 wording call (the `magazine-040` replacement sentence, drafted and waiting),
  and log rotation / `docker system prune`.
 - If a reply asks for a §"Readback" append (the lane's standing convention), it lands as one.
 ### Ask
 One line from Alexander, and it is the same one the last three ticks have asked for: **do the §4
 `cp` of collector `4e45021d…` + gate `c56230e5a075…` into `/root/.helm/bin/` — adopt or hold?** Every
 gate from Q31 to Q45S10 is verified and unmoved in production because `HELM_COLLECTOR` reads 0 in
 the deployed bin. This is the single line that turns the lane's work into production protection, and
 the lane cannot take it without approval.
