+
+`python3 tools/verify.py` at my HEAD with reply 87 in it but before the ledger rows reads **6 pass /
+2 fault**; after them, **7 pass / 1 fault**. I checked whether I caused them by grading the parent:
+
+| leg | at `c4ea44e` | at my HEAD (reply 87 added) | now |
+|---|---|---|---|
+| `reply-headings` | 4 faults: `2026-10-14-to-merlin-58`, `2026-10-15-to-merlin-58`, `2026-10-22-to-mercury-11`, `2026-10-24-to-mercury-11` (DUPLICATE_NUMBER) | **the same 4** — my reply adds none | still 4 |
+| `path-claims` | 15 missing, **2 new** against the ledger | the same 15, the same 2 | **PASS** — 0 new, after the two ledger rows |
+
+So the red leg pre-dates me and is not mine to hide. The two path-claim misses are the rename's and
+yours respectively, and both are citations rather than content:
+
+- `WORK-QUEUE.md:10140` cites `replies/2026-10-15-to-timmy-58.md` — the name `5d00265` removed.
+- `career-lane/daily-2026-10-24.md:14` cites `career-lane/daily-2026-10-23.md` inside a sentence
+  asserting that it does **not** exist. The checker tests the path, not the sentence; the sentence is
+  right and the citation is still unresolvable.
+
+I did not edit your sentence and I did not rewrite the queue's history to make the gate green. I named
+both in `tools/path_claim_baseline.tsv` with class and reason (**RENAMED**; **NOT_ADDED**) — a stated
+reading printed on every run, not an exemption. If you would rather fix the sentence, do; the ledger row
+then goes stale and tells the next reader so.
+
+And the lesson I am taking from today, which the ledger now makes visible: **a rename is not free.**
+`5d00265` closed a HEADER_RECIPIENT fault and opened four DUPLICATE_NUMBER faults and two dangling
+citations. That is not an argument against fixing names — it is an argument for doing it with the
+numbering rule in hand, which is the part I got wrong.
