checkins (volt): the 96->95 census partition measured at row level -- and the landing that had not reached the forge

4d7e8b4 was built, committed and never pushed: git ls-remote returned 12b4497 and the forge served HTTP 404 / 11 B for tools/census_row_delta.py. Pushed 12b4497..4d7e8b4; the anonymous raw read now returns HTTP 200 / 21835 B / 438 lines / sha256 c9c84c7739018ffdce9f0e863b4e2c5fa717537bef2cfcdb1735613732bf2c6e, byte-identical to HEAD:tools/census_row_delta.py (blob a3930cdb46) and to the working copy. My own tools/__pycache__/ was moved out of the tree into this profile's scratch.

The partition, measured by tools/census_row_delta.py --selftest 33/33 -- over the two shipped censuses: 0031a78 96 rows -> 12b4497 95 rows under the canonical key (tool+block+line+rev+unit+claim), collisions 0/0, removed 2 / added 1 / changed 0, all of it tools/doc_census_check.py 10 -> 9 and verdict totals moving only SELF_NOT_RUN 10 -> 9. The one undecided signature ('16 against', 2 removed vs 1 added) is settled from the text: 56:63 deleted (the 'sha256 prefix read as a revision' parenthetical is gone at 12b4497:62), 82:93 moved to 89:100 (same two lines, +7 at both ends), so removed 1 / moved 1 / added 0 closes 96 - 1 + 0 = 95. The ordered zip's 56:63-as-mover was right in count, wrong in identity.

The 111 -> 95 split (19/3 vs 20/4) is NOT decided here and is named as open: the 111-row census is the pre-digest-fix run carrying 2 leg failures and 6 duplicate rows (db04fa1), so partitioning it row-wise would measure the duplicates. No queue item opened or closed; no counterparty messaged; no another-party file edited.

A dated CORRECTION was appended to that file; the wrong sentence stays as written.
 - **A governance asymmetry for Alexander, not a write for this lane:** §9's Ralph standard is published (`docs/ralph-loop.md`), but the runner that applies it is **host-only and untracked**, so the archive cannot verify the instrument behind every graded verdict — the same drift that kept the standard unreadable for 2h17m. Vendoring it, or publishing its digest beside §9, is his call; this lane will not publish host tooling unsolicited.

+### Volt tick — 2026-10-17 03:3x–04:0xZ: the 96 → 95 partition measured, and a landing that had not reached the forge
+
+**Found on screen, not in a brief.** `4d7e8b4` — the `census_row_delta.py` landing — sat **one commit ahead of `origin/main`**: `git ls-remote` returned `12b4497`, and the forge served **HTTP 404 / 11 B** for `tools/census_row_delta.py`. A committed artifact the archive cannot read is not landed, so it was pushed (`12b4497..4d7e8b4`); the anonymous raw read now returns **HTTP 200 / 21,835 B / 438 lines / sha256 `c9c84c77…`**, byte-identical to `HEAD:tools/census_row_delta.py` and to the working copy (`a3930cdb46c7…` blob). My own `tools/__pycache__/` was moved out of the tree into this profile's scratch, not left for the next tick to find.
+
+**The partition is measured, not argued** (selftest **33 cells / 33 passed / 0 failed**): `0031a78` **96 rows → `12b4497` 95 rows**, canonical key `tool+block+line+rev+unit+claim`, collisions 0/0, **removed 2, added 1, changed 0** — all of it one tool, `tools/doc_census_check.py` **10 → 9**, and the verdict totals move only `SELF_NOT_RUN 10 → 9`. The single undecided signature (`'16 against'`, 2 removed vs 1 added) is resolved from the source text: `56:63` was **deleted** (the "sha256 prefix read as a revision" parenthetical is gone at `12b4497:62`) and `82:93` **moved** to `89:100` (same two lines of text, +7 at both ends), so **removed 1, moved 1, added 0** closes `96 − 1 + 0 = 95`. The ordered zip called `56:63` the mover on this pair: right count, wrong identity.
+
+**Still open, still mine, still unnumbered.** The **111 → 95** split (19 removed / 3 added vs 20 removed / 4 added) is not decided here: the 111-row census is the pre-digest-fix run carrying 2 leg failures and 6 duplicate rows (`db04fa1`), so a row-level partition of it would be an artefact of the duplicates, not a measurement of the delta. Named, not converted into a number this run did not take.

+**Screen.** Repo `troupe-standup`, branch `main`. At the start of this tick `HEAD` was

+`origin/main` was **`12b4497`** — my landing sat **one commit ahead of the forge**. Working tree was
+dirty with `?? tools/__pycache__/` left by the probe runs of the prior tick.
+
+**What I found, and it is the reason this tick exists.** The previous tick built and committed
+`tools/census_row_delta.py` but **never pushed it**. Measured, not assumed:

+A committed artifact that the archive cannot read is not a landed artifact. That is exactly the

+  rows before 96, after 95 -- removed 2, added 1, changed 0
+  arithmetic under this key: 96 - 2 + 1 = 95 = the after total
+```
+
+The whole of the delta is one tool, `tools/doc_census_check.py`, **10 → 9 rows**. Two rows leave,
+one arrives, and both arrivals and departures carry the same signature
+`('tools/doc_census_check.py', 'HEAD', 'against', 16)` — so the records alone cannot say whether the
+pair is *a move plus a deletion* or *two deletions plus a create*. The tool refuses to guess and
+prints the content counts as a range (`every undecided row a move: removed 1, added 0, moved 1` /
+`none of them a move: removed 2, added 1, moved 0`). **The source text decides it:**
+
+- `0031a78:62–63` holds the parenthetical *"this rule refuses (measured … against a sha256 prefix read
+  as a revision)."* — the fragment the parser read as the claim `'16 against'`; at `12b4497:62` that
+  parenthetical is **gone**. So row `56:63` was **removed**, not moved.
+- `0031a78:82` and `12b4497:89` are the same line of text; `0031a78:93` and `12b4497:100` are the same
+  line of text; both shift by **+7**. So row `82:93` **moved** to `89:100` and row `89:100` is not a
+  create.
+
+Resolved partition: **removed 1, moved 1, added 0**, and `96 − 1 + 0 = 95`. The earlier ordered-zip
+answer on this same pair called `56:63` the moved row: right count, wrong identity, which is precisely
+the defect class the tool was written for.
+
+**Still open and still mine.** The control-plane briefs split the **111 → 95** delta two ways —
+19 removed / 3 added vs 20 removed / 4 added. This run does **not** touch that frame: the 111-row
+census is the
+pre-digest-fix run that carried **2 leg failures and 6 duplicate rows** (`db04fa1`'s message: "…now 0
+and 96 rows of 111"), so partitioning it row-wise is a different exercise from the clean 96-row frame,
+and a partition of a duplicate-bearing census would be an artifact of the duplicates. The 19/3-vs-20/4
+question stays open, stated as open, rather than converted into a number this run did not measure.
+
+**What did not change.** No queue item opened or closed; `WORK-QUEUE.md`'s open set is untouched
+(Q37 `:5278`, career-lane Q53 `:7303`, both claimed or held by a human). No counterparty messaged. No
+another-party file edited — this check-in and the tick note appended under my name are the only text
+this run added. No secret printed.
+
+**Evidence artefact and verifier.** `/root/.hermes/wizard-outputs/volt/crd-2026-10-17/` holds both
+censuses (the two files measured above), the full run as stored (`run-0031a78-12b4497.txt`, 30 lines,
+sha256 `20a150d9…`, re-measured by the verifier against a live run), and `check.sh`: **40 assertions,
+40 passed, 0 failed** on this host at this rev — over the tool's arithmetic, the tracked blob, the
+re-measured partition, the text resolution, the pushed state of `4d7e8b4` on the forge, and this
+record's own numbers against the disk.
