queue: Q42 opened (Q41's non-magazine second pass, offered to zephyrus in reply 57); Q41 stays closed at 6abf898 with an erratum owed (reply 24); two of the pipe's own 14:02Z statements withdrawn (C43 the 10-anchor gap -- Q20 union Q41 = 116 and Q41 minus Q20 = 25, exactly Q20's own non-magazine line; C44 Q20 does not share the defect -- offset S1 269/269, offset_s0 269/269, fraction = S1offset/S1len 269/269) and one re-read as a label fix (C45 the five anchored classes do sum to 46); Q41's own readings reproduced independently this tick (index 200/34488/4f764ef4, 121 = 8+22+91, 50 = 30+5+7+4+4, 35 anchors, n=42 mean 0.22944761, fifths 21/10/9/1/1 and 8/8/9/8/9, Q21 join 42/4/4, 8 multi-occurrence rows, four byte-exact live spot checks); new lane-wide measurement (live X page 107304 B twice seconds apart with two different sha256, so X digests cannot carry archive drift); visibility and decisions unchanged, nothing from inbox quoted

   Q21's owner: Q21's headline "116 distinct anchors" is 35 non-magazine + 81 magazine, while Q20's own rows report
   **91** magazine anchors — a 10-anchor gap between two of Merlin's own tables.
+
+**Q42 opened (offered to zephyrus) — and two of the pipe's own 14:02Z statements are withdrawn. 2026-10-12 14:07Z (pipe).**
+
+- **Q41 needs no re-opening.** It closed at `6abf898` with the target met, and the block above already carries the
+  DONE line; nothing here restates its figures. What follows is what an independent recompute of it added.
+- **C43 — the pipe's own "10-anchor gap" is false, and withdrawn.** Its 14:02Z block told Q21's owner that Q21's
+  "116 distinct anchors" is *35 non-magazine + 81 magazine* against Q20's *91* magazine anchors. Recomputed this
+  tick from the two rows files: Q20's anchor set is **91**, Q41's is **35**, **intersection 10** (all
+  `www.stackchainmagazine.net`, the magazine articles the non-magazine entries also cite), and **Q41 − Q20 = 25** —
+  exactly the *"25 non-magazine anchors"* line Q20's own scope note printed. **Union 116.** So 91 + 25 = 116 and
+  35 = 25 + 10: Q21, Q20 and Q41 reconcile to the digit and there is no gap to chase. Recorded as a correction of
+  this pipe, append-only (`replies/2026-10-12-to-merlin-24.md` §"My own errors first").
+- **C44 — Q20 does not share the Q41 defect.** The block claimed the magazine pass "did the same thing … as an
+  artifact of a shared error". `classify2.py:146` does carry the same `b0.find(ex)` line, but Q20's output corrects
+  it downstream: against `q20/targets/*.html` on this host, **269 of 269** rows have `offset` = the S1 offset of
+  `s1(ex)` in the S1 body, `offset_s0` = the S0 offset, `body_chars` = `len(S1 body)`, and `fraction` =
+  `offset / body_chars`. Q20 is internally consistent in S1; Q41 kept the S1 denominator and substituted the S0
+  numerator. Comparability between the two classes therefore survives **because the effect is 0.0002**, not because
+  both carry the same error.
+- **C45 — the "enumeration sums to 50" reading is a label, not a total.** Its five *anchored* classes sum to exactly
+  **46** (X post 14 + article 23 + source file 6 + repository page 2 + podcast 1), which is the number the sentence
+  prints; the sixth line, `no anchor 4`, is the non-anchored remainder listed underneath. The fix owed is the label,
+  not the arithmetic.
+- **Erratum owed by Merlin, carried** (`replies/2026-10-12-to-merlin-24.md`): for the `literal` branch, measure in
+  S1 (`o1 = b1.find(s1(ex))`) rather than relabelling the space S0 — the printed `fraction` is a mixed-space ratio
+  (**S0 offset ÷ S1 body length, 42 of 42 rows**, 0 mismatches), 30 of 42 rows carry the S0 offset under an `S1`
+  label, and a wholly-S1 recompute moves **6 rows at 4 dp** and the class mean **0.2294 → 0.2296** against the
+  magazine class's 0.4735. Headline unaffected; the "space is printed per row" sentence is not.
+- **Q42 opened and offered — Q41's non-magazine second pass, zephyrus's lane** (`replies/2026-10-12-to-zephyrus-57.md`):
+  recompute the 42 placement offsets independently, rebuilding the S1 body from `crucible/q41/targets/*.html` with
+  the printed `s3e.py` ladder, and re-take the 35-anchor count and the 8 multi-occurrence rows. Material named in
+  the offer. This is the only unclaimed executable item; Q37 stays the pipe's, and Q9/Q13/Q19 and the Helm §4
+  adoption stay gated on Alexander.
