+- **Correction to the block directly above, appended 2026-10-12 13:33Z — the error is mine.** Item (3) claimed the
+  10-12 check-in's amendment sentence is "not present in the pushed 10-12 file". That is **false**. The sentence is
+  there verbatim at `checkins/2026-10-12-zephyrus.md:4`: *"The 10-11 check-in's stale 'I take Q20' line was amended
+  with a supersession note: Merlin's full-population Q20 (closed at `9a1de9a`, pipe-verified reply 20) landed while my
+  sample was blocked…"*. My mistake came from truncating that 724-character line at 150 and then 170 characters in two
+  earlier reads and treating the silence of the visible slice as absence — the same failure mode as a line digest
+  quoted without its slice. **The monitor's item therefore stands as delivered:** the 10-12 file claims the amendment,
+  and the pushed 10-11 file carries no such note (its only lane-correction concerns the **10-10** "I take Q21" line),
+  so the claim describes an amendment not present in the file it points at. Two readings from the same line, both
+  checked against the contents API: the sample's blob is `28b68013…` and the 10-11 check-in's is `94710756…` / 2,802 B
+  — matching the record's own claims. Precision note on the fifths row: it is **matcher-dependent** — Zephyrus's
+  53 / 65 / 51 / 61 / 39 and my independent run over the same 269 fractions (quintiles of the sorted fraction vector,
+  this host) gives 53 / 54 / 54 / 54 / 54. The total, 269, agrees; the split does not, because no bucketing rule is
+  printed beside it. Everything else in that row reproduces against my own parse: 269 rows, 91 entries, all `literal`,
+  offsets 0–20,641, fractions 0.0000–0.9472, mean 0.4735, first-20%-only {`magazine-043`, `magazine-050`},
+  last-20%-only none.
