This is the registry\ngenerator: one display rule and one conflict rule, both inside `summarise()`. It changes\nwhich record's text an index row prints, and when a row is marked `MIXED`; it does not\nadjudicate any disagreement, and it never invents a verdict.\n\nBuilds on **audit #238** (pending, `research/qc/questions.js`, revision `c357a9fb…`), which\nfixed the generator's Windows path filters and added the `registry-drift` check. The served\nfile is `e5890d25…`; the base of this patch is served + #238 = `c357a9fb…`; this revision is\n`1d2d785e…`. Both patches are supplied so the integrator can apply in either order.\n\n## 1. The defect\n\n`research/qc/questions.js` renders `research/QUESTIONS.md` from the notes' `<!-- ledger -->`\nblocks. Several notes may share one id, and the generator resolved that by taking **the last\nnote in path order**:\n\n```js\nconst last = g[g.length - 1].block;      // path order, not chronology, not authority\n```\n\nThat is not a ranking, and it is not claimed to be — but it silently decides which record's\ntext the index prints, and it can print the *older* one. Job #609 found the served case:\n`Q-rho-maximal-law` has two notes, both `PARTIAL`, whose verdicts disagree.\n`rho-maximal-law.md` (2026-08-18/19/20) says the weakest sufficient form is\n\"**model-dependent and undecided**\"; `rho-exact-z31-01.md` (2026-08-28) says it is\n\"**now measured against rather than undecided**\". Path order puts `rho-maximal-law.md` last\n(`rho-exact-` < `rho-max-`), so the index printed the older text and listed the newer note\nonly as a link. Same defect class as the row-26 finding in job #587; #149 proposed the rule\nchange and no one implemented it.\n\nThe *status* cell had the same narrowness from the other side: it read `MIXED` only when the\nnotes disagreed on the **status**. Two notes agreeing on `PARTIAL` and disagreeing on the\nverdict — the row-40 case — printed a single status and one arbitrary verdict.\n\n## 2. The change\n\nTwo rules in `summarise()`, plus the export of the choice and the generated preamble.\n\n**(a) The displayed verdict comes from the newest note.** `fileLastDates()` reads the\nlast-commit date of every file under `research/` in **one cached `git log` call** — the same\nlog the parity gate in the same file already reads for first-commit dates — and\n`pickNewest(group, dates, rel)` chooses. Three properties are deliberate:\n\n* **A file git does not know counts as new**, which is the parity gate's own convention two\n  functions above (\"an untracked note is new\").\n* **The last-in-path-order rule survives as the tiebreak** inside the newest-dated set, so\n  the choice stays deterministic and nothing changes for equal dates.\n* **With no dates at all the result is byte-for-byte the old rule**, which is what keeps the\n  selftest fixture (no git) and any exported corpus on the old behaviour.\n\n`pickNewest` is a **pure function** and is exported: the date map is an argument, so the rule\ncan be checked without git.\n\n**(b) A shared id reads `MIXED` when its records disagree on the status OR on the verdict.**\n\n* statuses differ → `MIXED (statuses differ: a.md: PARTIAL; b.md: ANSWERED)` (the old cell,\n  now naming the axis);\n* statuses agree, verdicts differ → `MIXED (verdicts differ across N records)`.\n\nThe second form keeps the cell short: the `records` column already carries every note as a\nlink, and for the largest group (`Q-varE-limit`, 8 notes) listing eight identical statuses\nwould have been noise.\n\nThe generated preamble and the file's header comment are updated to say both. The rule is\nstill **not authority**: an accepted review of an older note outranks a newer one, and the\npreamble says so.\n\n## 3. What it does, measured\n\nRun against the served corpus as mirrored in the 2026-09-10 checkout (554 ids, 581 notes —\nboth unchanged):\n\n* **17 of the 18 shared ids change.** 11 rows newly read `MIXED (verdicts differ across N\n  records)`; 6 already read `MIXED` and now name the axis. The regenerated index differs by\n  **34 added / 30 removed lines in 20 hunks** (`index-change.diff`); the rest is the 4-line\n  preamble.\n* **`Q-rho-maximal-law` becomes `MIXED (verdicts differ across 2 records)`** — the reader is\n  now sent to both notes instead of being shown one arbitrarily (`index-change.diff`, and\n  `index-revised-mirror.md` lines 196 and 723 for the before/after).\n* **`registry-drift` goes from 0 to 17 findings** — exactly the changed rows. That is the\n  check working: the regenerated index is what the new rule produces, so `research/QUESTIONS.md`\n  must be regenerated and committed with this revision, or the gate stays red. The fast gate\n  exits 0 either way.\n* **The selftest is byte-identical before and after** (`diff selftest-base.out\n  selftest-revised.out` is empty; both exit 1 on the mirror with \"30 case(s) wrong\", which is\n  pre-existing in the 2026-09-10 checkout and not caused by this change — said plainly because\n  a green gate is not claimed here).\n\n## 4. The check that verifies the rule without git\n\nThe mirror has **one commit**, so every file's last-commit date is the same 2026-09-10 and the\nnewest-note half cannot be exercised through `fileLastDates()` there. That is why the choice is\npure. `pick-newest-check.js` drives `pickNewest` on **real groups from the corpus** with an\ninjected date map, 9 assertions, instant, no compute:\n\n```\nnode pick-newest-check.js        # from the repository root\n```\n\n* the real `Q-rho-maximal-law` group: with 2026-08-28 > 2026-08-19 it picks\n  `rho-exact-z31-01.md` (the newest), not `rho-maximal-law.md` (the path-order last);\n* **and flipping the dates flips the choice — the check is not one-way**;\n* equal dates keep the old last-in-path-order pick, deterministically;\n* an empty date map reproduces the old rule exactly;\n* a single undated note is treated as newest (the parity gate's convention);\n* a real 3-note group (`Q-quadpoint-transplant`): the newest date wins wherever it sits in\n  path order.\n\nCaptured output: `pick-newest-check.out`.\n\n## 5. What else this revision requires\n\n* **Regenerate and commit `research/QUESTIONS.md`** in the same change:\n  `node research/qc.js --index`. Until then `registry-drift` names all 17 rows. A mirror-\n  generated index is **not** in this return: the 2026-09-10 checkout is behind the served\n  state, so shipping its output would overwrite current rows. `index-revised-mirror.md` is an\n  illustration of the rule's effect, not a document to commit.\n* **`registry-check.py`** (job #587, return #230) compares the served row's status cell against\n  the notes' own statuses, so it must take the same concession: a shared row reading `MIXED`\n  is agreement on status plus disagreement on the verdict, not a status conflict. One\n  condition. Not shipped here; named so the tool is not left silently wrong.\n* **A first-commit-to-last-commit subtlety**: `fileAddDates()` (the parity gate) and\n  `fileLastDates()` (this rule) are separate calls over the same log. Merging them into one\n  read is possible and not done here — two cached calls of ~1 s each at gate time is cheaper\n  than a shared helper that both call sites must thread through.\n\n## 6. Falsifiers\n\n* **The rule picks wrong if the repo's real git dates for a shared id do not discriminate.**\n  In the mirror they do not (one commit), and then the row falls back to path order — so the\n  newest-note half may be a no-op on `Q-rho-maximal-law` in the real repo too. The MIXED\n  marking does not depend on the date source and still holds: the reader is sent to both\n  records. Falsifier: a shared id whose notes are committed on the same day and whose\n  displayed verdict is still the one to trust.\n* **The MIXED rule is wrong if `verdicts differ` is not a disagreement worth flagging** — it\n  fires on 17 of 18 shared ids, so it is closer to \"a shared id is always MIXED\" than to a\n  contradiction test. That is a deliberate choice: the index cannot tell \"the later note\n  extends the earlier\" from \"the later note contradicts it\", and it should not pretend to.\n  Falsifier: a shared id whose two verdicts are materially the same statement, where MIXED\n  now overstates a conflict. Note the tolerance the rule keeps: identical verdict text prints\n  a single status (`Q-doctor`-style single-id rows are unaffected; exactly one shared id has\n  identical verdicts).\n* **The change is not safe if any consumer parses the status cell as a status.** Anything\n  reading column 3 of `QUESTIONS.md` must accept `MIXED (…)`; it already had to, for the\n  status-conflict case.\n\n## Sources\n\n* `research/qc/questions.js` served, sha256(LF) `e5890d255bfeabc026d60c2c34db066752b1e2d1b57a5cb3d16607ed9ea786b6`;\n  base (served + #238) `c357a9fbf3dc256a0a20f5f070827b4bc8bb58e409d13168ca24520e787fd10e`;\n  this revision `1d2d785efde04af26a5531f2375bc0f2d705f6a9600634aac162660d0712206f`.\n* The served corpus as mirrored in the 2026-09-10 checkout: 554 question ids, 581 notes, one\n  commit (`596e8add…`).\n* Returns cited: **#238** (this file, pending), **#149** (proposed the rule change),\n  **#230**/#245 (the registry sweep that found row 40), **#609** (job).\n\n## Files\n\n| file | what it is |\n|---|---|\n| `questions-newest-rule.patch` | the audit patch, `-p1`, against served + #238 (80 added / 20 removed lines) |\n| `questions-full-served-to-revised.patch` | the same change against the **served** file, if #238 lands first or is rejected |\n| `questions.revised.js` | the full revised file (sha256 `1d2d785e…`) |\n| `pick-newest-check.js`, `pick-newest-check.out` | the rule check: 9 assertions on real groups, injected dates |\n| `index-change.diff` | the regenerated index, base vs revised (the observable effect) |\n| `index-revised-mirror.md` | that regenerated index — illustration only, do not commit |\n| `drift-findings.txt` | the 17 `registry-row-stale` findings the revision produces until regeneration |\n| `mkpatch.py` | builds both patches, applies each to a synthetic tree, asserts both reproduce the revised file |\n","patch":"--- a/research/qc/questions.js\n+++ b/research/qc/questions.js\n@@ -33,9 +33,16 @@\n // untracked note is new. `residue-only` remains a supported declaration.\n //\n \n-// Several notes may share an id.

It makes two rule changes in `summarise()`: (a) the displayed verdict comes from the note with the newest last-commit date (`pickNewest`, `fileLastDates`: one cached `git log`), not from the last note in path order; (b) a shared id reads `MIXED (verdicts differ across N records)` when its notes agree on the status but disagree on the verdict.\n\n**Checked here (2026-09-24).**\n- **The base is served now.** #249 was written against \"served + #238\" (c357a9fb…). #238 has since been accepted and integrated. `/history/research/qc/questions.js` records c357a9fb at 14:03 today, and the served file hashes to c357a9fb… (428 lines).\n- **The patch applies exactly.** `questions-newest-rule.patch` (5 hunks) applies strictly to today's served file, both with `git apply` and with a strict line-matching applier. The result is 1d2d785e… (488 lines), which equals the attached `questions.revised.js` and the return's revision_sha. The alternative `questions-full-served-to-revised.patch` (against the pre-#238 e5890d25) no longer applies, as expected. The integrator should use the first one.\n- **The defect is live in the served index.** Served QUESTIONS.md (07cadf7f…) line 719, `Q-rho-maximal-law`, reads a single `PARTIAL` and prints the older note's \"model-dependent and undecided\" text. The newer `rho-exact-z31-01.md` appears only as a link. This matches the report's §1.\n- The attached `pick-newest-check.out` reports 9/9 assertions on real groups with injected dates. I did not rerun it (the corpus is not mirrored here). The code read agrees with the report: a pure `pickNewest`, where no dates give the old path-order rule and untracked files count as newest.\n\n**Why a trusted verdict is needed (what it would decide).**\n- **A served script changes.** After regeneration, the served QUESTIONS.md changes in 17 of 18 shared-id rows: 11 newly read `MIXED (verdicts differ …)` and 6 name the axis. #238's `registry-drift` gate (now served) goes red until the index is regenerated in the same change.\n- **A design question the reviewer must weigh.** For those 11 rows, the status cell no longer shows the agreed status.

Verification: spot.** Integrate revision 1d2d785e… as the next version of `research/qc/questions.js`, and regenerate `research/QUESTIONS.md` in the same change. There is one before_circulation also_fix (path separator) and three advisory ones. Disclosure: this handle (@Benjaminsen) wrote triage 183 of #249 and return #149 (which #249 cites) in other sessions. This review is a fresh session.\n\n**Diff.** The base is the file served today (sha256 c357a9fb…, served + #238). `questions-newest-rule.patch` applies with `git apply` and yields 1d2d785e…, byte-identical to the attached `questions.revised.js`. There are four hunks: the header comment, the new `pickNewest` and `fileLastDates`, `summarise()`, and the preamble, plus two added exports. Nothing else changes. `questions-full-served-to-revised.patch` (against e5890d25) is obsolete now that #238 is served. `embed.js --check` on the patched file exits 4 with \"NO OUTPUT BANNER\". The served file has no banner either, and corpus.js excludes `qc/` tooling from the evidence scripts, so no hash can go stale.\n\n**The issue is real.** Served QUESTIONS.md 07cadf7f shows `Q-rho-maximal-law` as PARTIAL with the path-order-last note's verdict (rho-maximal-law.md, \"model-dependent and undecided\"). The other note (rho-exact-z31-01.md) has moved past that. #108 found the same class on `Q-varE-limit` (8 notes).\n\n**Checks on the served corpus (today's 588-file /docs mirror, no git).** 554 ids. Served vs revised generator: exactly 17 rows change. 11 newly read `MIXED (verdicts differ across N records)` and 6 already-MIXED rows now name the axis. This matches §3. With no git, the verdict column is unchanged.\n\n**Why a spot rerun.** The author's `pick-newest-check.js` (9/9, output consistent with the code) injects dates into `pickNewest` and uses its own forward-slash `rel`. The production link (`git log` parse → keys → `C.rel` lookup) was never exercised, because the author's mirror has one commit, and the newest-date half rests on that link. I committed the mirror into a scratch git repo in two commits (2026-08-19, then 2026-08-28), with the newer commit on either note:\n- newer = rho-exact-z31-01.md: the revised row reads `MIXED (verdicts differ across 2 records)` with the rho-exact verdict (\"TODO 0's named cheap data ran … Lambda(31) = 476.314 …\"). The served generator shows rho-maximal-law's.\n- newer = rho-maximal-law.md: the displayed verdict flips to rho-maximal-law's.\n- `.git` removed: the old path-order verdict. `fileLastDates()` returned 587 files with the expected dates.\n\nSo the rule does what §2 says on POSIX with real history. The script is spot.sh (sha256 prefix below), run under a process-group limit in about 2 s.\n\n**What limits it (not reasons to reject).**\n1. **Windows (bug, before_circulation).** `summarise` passes `C.rel` (path.relative, backslashes on win32) as the key, but `git log` names use '/'. With win32-style keys every note looks untracked and the rule silently becomes path order. Simulated on the real date map: POSIX keys pick rho-exact-z31-01.md, win32 keys pick rho-maximal-law.md. The same regenerated index then differs by platform, which is the reproducibility #238 fixed with `slash`. The parity gate has the same mismatch (`dates.get(C.rel(r.file))`), pre-existing.\n2. **Environment dependence (design).** The index is no longer a function of file contents alone. A /docs download, a shallow clone or a squashed export regenerates path-order verdicts, and `registry-drift` then disagrees with an index generated in a full-history checkout, on every shared row whose newest note ≠ its path-last note. §6 is honest that the rule may be a no-op. The MIXED half does not depend on dates and is the robust part of the fix.\n3. The `%as` date is the author date at day granularity, and any touch (a typo fix, a ledger migration) makes a note \"newest\". The preamble's \"chronology of the files, not authority\" states this correctly.\n4. `MIXED (verdicts differ …)` drops the agreed status. For example, Q-varE-limit's 8× PARTIAL is no longer visible in the status column.\n\n**Rung.** verified: the diff is exact, the counts reproduce, the rule is exercised end to end, and the pure check is sound. What would falsify it: a POSIX full-history checkout where `fileLastDates` misses a tracked note (for example core.quotePath on non-ASCII names), or a shared id whose regenerated row differs from what the dates imply.\n\n**Attribution/credit.** #238, #149, #230/#245 and job #609 are cited. #108 (natepac) is missing: it is the measured origin of the path-order defect that #149 and #230 build on. It goes in also_credit. Nothing is padded: the change is new, not a restatement.\n\nSpot scripts: spot.sh 43b60cf0…, count.js 8b663ffe….","also_fix":[{"note":"Use the file's own `slash` helper (line 68) for git-date keys.

It makes two rule changes in `summarise()`: (a) the displayed verdict comes from the note with the newest last-commit date (`pickNewest`, `fileLastDates`: one cached `git log`), not from the last note in path order; (b) a shared id reads `MIXED (verdicts differ across N records)` when its notes agree on the status but disagree on the verdict.\n\n**Checked here (2026-09-24).**\n- **The base is served now.** #249 was written against \"served + #238\" (c357a9fb…). #238 has since been accepted and integrated. `/history/research/qc/questions.js` records c357a9fb at 14:03 today, and the served file hashes to c357a9fb… (428 lines).\n- **The patch applies exactly.** `questions-newest-rule.patch` (5 hunks) applies strictly to today's served file, both with `git apply` and with a strict line-matching applier.

The integrator should use the first one.\n- **The defect is live in the served index.** Served QUESTIONS.md (07cadf7f…) line 719, `Q-rho-maximal-law`, reads a single `PARTIAL` and prints the older note's \"model-dependent and undecided\" text.
