{"id":62,"job_id":192,"problem_id":1,"lane_id":3,"type":"explore","user_id":1,"model":"claude-opus-5","provider":"anthropic","report_md":"# Job #192 (explore): `Q-scanstat-t37-prereg` re-scored against its producer\n\n**Question.** `Q-scanstat-t37-prereg`: \"What is the moving-sum exponent H at T_37, predicted before any producer for the pass existed?\"\n\n**Standing record.**\n\n- **The prereg's own block** still reads OPEN, \"Pre-registration only\". Return #59 listed it among the eleven stale ids.\n- **Its scoring note** is `research/history/staging/scanstat-t37.md` (`Q-scanstat-t37`, ANSWERED).\n- **The downstream closed-routes row** in `research/OUTCOMES.md` (line 2810) marks the linear exponent rule \"REFUTED, twice blind\".\n- **No adversarial pass** on the T₃₇ scoring is in the served record. The red-team files in `history/staging/` cover `perfold`, `mp-window`, `sofic`/`scanstat` (T₂₉ only) and `zonegap-01`.\n\n**Rungs used below.**\n\n- **VERIFIED:** a check that ran here and matched, with its range stated.\n- **MEASURED:** a figure from an embedded OUTPUT block. It is not re-derived here.\n- **REGISTER FACT:** what a served document says at the quoted line, in snapshot `main` fetched 2026-09-11.\n\n**Compute.** One re-run of the producer's 0.1 s `--combine-only` step, on one core under a 60 s alarm. The census itself was not re-run. `cpu_hours` = 0.\n\n## Caveats first\n\n- **The census was not re-derived.** The five shard moment files were produced by the original 5-shard run: 35.2 min per shard, about 3.1 h single-threaded per `scanstat-t37-02-validate.js` (4). I re-ran only the step that combines those moments, runs gates 1-4 and scores the prereg.\n- **What that re-run shows, and what it does not.** It shows that the served moments produce every printed number in the embedded block. It does not show that the moments are the true moments of T₃₇. For that, the record relies on:\n  - the gates inside the combine: the slot count equals ∏(p−2), maxsum₁ = 528, Σ = m·W at all twelve m, and mean₁·D = W;\n  - the validator's gates 5 and 6 at T₂₃ and T₂₉: the new engine against 48 published columns, sharded against unsharded.\n- **H\\*₆ is post-hoc.** The prereg labels it so (§0), and it decides nothing. I report it only because the prereg obliges both numbers to be reported.\n- **Conflict of interest.** My person owns the repo. Return #59 (this session) is what pointed here.\n\n## What I did\n\n1. Read `scanstat-t37-prereg.md` in full (criterion §2, secondaries §3, gates §4, plan §5, producers §7).\n2. Read `scanstat-t37.md` in full, `OUTCOMES.md` line 2810, and `scanstat2.md`'s ledger plus its T₃₁ scoring and post-hoc lines.\n3. Read the embedded OUTPUT blocks of `research/scanstat-t37-04-run.js` (the driver) and `research/scanstat-t37-02-validate.js` (gates 5 and 6), and the served run log `research/t37-partials/t37-run.log`.\n4. Fetched the five served shard files `research/t37-partials/t37-shard-37-{0..4}-of-5.json` and the driver's static dependencies. After checking all five parse, ran the embedded invocation `node research/scanstat-t37-04-run.js --level 37 --shards 5 --outdir research/t37-partials --combine-only --h31 0.345957`. Diffed the normalised stdout line by line against the embedded body.\n5. Ran `node research/qc.js embeds` on the fetched scripts.\n\n## Findings, each with its rung and what would falsify it\n\n### F1. The registered verdict reproduces, and the two quoted distances are one miss in two units\n\n**Rung:** VERIFIED (re-run combine output, plus arithmetic).\n\n- **The criterion.** Prereg §2 makes band membership the criterion: \"INSIDE [0.369866, 0.392641]\" or \"OUTSIDE the band\". The re-run prints `VERDICT: OUTSIDE the band.` for measured `H(T_37) = 0.3565 +/- 0.0068` (0.356548 in the note).\n- **The ledger's \"3.63 of its own s.e.\"** is the distance to the point prediction in measurement s.e.: (0.381254 − 0.356548)/0.0068 = 0.024706/0.0068 = **3.63**.\n- **`OUTCOMES.md`'s \"6.90 band standard errors\"** is the same distance in the band's `se_mean` (prereg line 101: 0.003578): 0.024706/0.003578 = **6.90**. The T₃₁ half of that row reads 0.013445/0.002710 = **4.96** and 0.013445/0.0068 = **1.98** (1.99 on unrounded inputs). Here 0.002710 is the T₃₁ band half-width 0.008625 divided by t₃ = 3.182446.\n- **The other registered readings, from the re-run output:**\n  - √m kill: `H + 3 se = 0.3770 < 0.5`;\n  - direction: `H(T_37) > H(T_29) = 0.3367`;\n  - weak secondaries: `sd_1 … measured 25.1586 OUTSIDE` [25.2384, 38.5957], and `c … measured 26.7315 OUTSIDE` [26.7371, 37.3394];\n  - kill criterion: `A' 0.4386 vs B' 0.4619 -> A' WINS`.\n\n  All four match the note's §2.\n- **Falsifier.** A registered criterion other than band membership, or a re-run printing INSIDE. Neither.\n\n### F2. The embedded block reproduces from the served shard moments, but its out-sha256 cannot\n\n**Rung:** VERIFIED.\n\n- **The diff.** Normalised with `research/qc/tailfmt.js`, the re-run's 82 stdout lines equal the embedded body's 82 lines at 81 lines.\n- **The one differing line is the last, a wall clock:**\n\n  ```\n  embedded: [DATE 20:24:39] done\n  this run: [DATE 13:46:34] done\n  ```\n\n- **The cause.** `tailfmt.js`'s `DATE` rule, `\\b\\d{4}-\\d{2}-\\d{2}(?:T[\\d:.]+Z?)?`, masks an ISO date and an attached `T…` time, but not a clock time written after a space. So the normalised stdout of this producer changes on every run.\n  - Embedded out-sha256: 73f3c1bab236d6da0ffa394d58c92f7b40d5098e81d19c15aff83a9351120cf5. The embedded body still hashes to it.\n  - This re-run: bf928129e653ef5708dbb9b230ca46cb46e17c6c014847ce9489ed728a7c1e66.\n  - `embed.js --check` would report the run as not reproducing on any machine, at any time.\n- **Static check.** `node research/qc.js embeds` over the fetched scripts (6 scripts): `0 finding(s)`, `clean`.\n- **Falsifier.** A second re-run whose normalised stdout hashes to 73f3c1ba…. That would need the same wall-clock second as the embed.\n\n### F3. The shard moments are not bound by the fingerprint\n\n**Rung:** REGISTER FACT, with the hashes VERIFIED.\n\n- **What the fingerprint holds.** The driver's fingerprint (file lines 225-236) has `invocation`, `code-sha256`, `out-sha256`, `body-lines`, `restamped`, `streams`, `node`, `embedded` and `elapsed`, and no `inputs:` line.\n- **Why no static scan can bind the shards.** `embed.js` writes `inputs:` only for dependencies its static scan finds (lines 159 and 428). The shard files arrive through `--outdir` at run time. The four static reads (lines 50, 51, 82, 95) are also absent.\n- **What binds the block to its moments today.** Only a re-run like F2's. The served shard files hash to:\n\n  | file | sha256 |\n  |---|---|\n  | `t37-shard-37-0-of-5.json` | 19e32356d75dc64979ab6c5d9a613fbcc1dcf42ba39821fc351e615023035ff2 |\n  | `t37-shard-37-1-of-5.json` | 2793575602c1a4684a94d758ae8fac9a2b32e84b3166c3530391e11d01c7410c |\n  | `t37-shard-37-2-of-5.json` | 2f36b0dbfab4284674ea1924f6407a222e399803c953a27432916bc2db13b005 |\n  | `t37-shard-37-3-of-5.json` | 3624836da7ab43a4c791ebe8583a2c1c2238020bf60fcf8b743c55371d930536 |\n  | `t37-shard-37-4-of-5.json` | 733bd5b18d2cacc8c634b729bca12e293e1b689b14026374399e2f02fa5afec8 |\n\n  The served driver hashes to 4dd628370d0d2f6dabecfcaa43c1b461589c1bf2ec9d229992bf3a3f598d7d90.\n\n### F4. The prereg's post-hoc H\\*₆ was computed, and lands inside its band, but the scoring note never reports it\n\n**Rung:** REGISTER FACT, with the numbers VERIFIED by the re-run.\n\n- **The obligation.** Prereg §0 (lines 34-45) \"pre-commits to reporting **both**, in this order and with these labels\": H\\*₅ as the criterion, and H\\*₆ \"POST-HOC, computed after T₃₁ was known\".\n- **The first run did not compute it.** The run log's final section ends `(8) POST-HOC six-level refit NOT COMPUTED: no --h31 supplied … re-run with --combine-only --h31 <measured H(T_31)> once the sibling pass lands`, then `[2026-08-19 20:14:52] done`.\n- **The embedded block did.** It is that recombine, with `--h31 0.345957` and its own done line at 20:24:39. It prints:\n\n  ```\n  (8) POST-HOC, LABELLED POST-HOC: the six-level refit including T_31\n      H = 0.228096 + 0.005494 * lnD   ->   H*_6(T_37) = 0.371528   band [0.355897, 0.387158]\n      measured 0.356548, miss 0.014979 = 2.20 s.e.,  inside the post-hoc band\n  ```\n\n  The re-run reproduces it.\n- **The note is stale against its own producer's embed.** `scanstat-t37.md` §4 (lines 59-62) still says the refit \"should be run when the sibling's H(T₃₁) lands\". Neither the note nor `OUTCOMES.md` line 2810 carries H\\*₆.\n- **Consequence.** None for the verdict: the criterion is H\\*₅ only, and \"twice blind\" refers to the five-level law. A reader of the note or the outcomes row does not learn what the labelled post-hoc number is, which is that the six-level line's band contains the measurement.\n- **Falsifier.** A served statement of H\\*₆ = 0.371528 in `scanstat-t37.md` or its successor. None was found.\n\n### F5. The run's timing and the validator's gates check out; one naming inconsistency\n\n**Rung:** VERIFIED / REGISTER FACT.\n\n- **Timing.** The run log starts all five shards at `2026-08-19 19:39:39` and ends at `20:14:52`, which is 35.2 min, matching the embedded \"wall per shard 35.2 / … min\". The log's early ETAs of about 45 min were early estimates.\n- **Gates 5 and 6 ran at both required levels.** The validator's embedded block shows `unsharded vs 5-shard: identical, every field` at T₂₃ and at T₂₉. It shows 24 `yes` matches per level (maxsum_m and sd_m at twelve m), and `H(T_23) = 0.3216 +/- 0.0096` and `H(T_29) = 0.3367 +/- 0.0080` equal to the published values.\n- **Naming.** `scanstat2.md` lines 141 and 320 call the post-hoc fit the \"seven-level refit\". The driver prints \"the six-level refit including T_31\": six levels in, T₃₇ predicted.\n\n## Proposed text (not applied)\n\n**Ledger block, `scanstat-t37-prereg.md`.** The status word is the owner's call; `scanstat2-prereg.md` uses CLOSED for its sibling.\n\n```\n<!-- ledger\nid: Q-scanstat-t37-prereg\nstatus: CLOSED\ntodo: none\nquestion: What is the moving-sum exponent H at T_37, predicted before any producer for the pass existed?\nverdict: Sealed and committed alone before any producer existed; scored in scanstat-t37.md, where the measured 0.356548 +/- 0.0068 falls OUTSIDE the sealed band [0.369866, 0.392641] (3.63 measurement s.e., 6.90 band s.e. from 0.381254), sqrt(m) stays refuted (H + 3 se = 0.3770) and the rise continues; the labelled post-hoc six-level H*6 = 0.371528 contains the measurement at 2.20 s.e.\n-->\n```\n\n**`scanstat-t37.md` §4.** Replace \"should be run when the sibling's H(T₃₁) lands\" with the embedded section (8) figures, labelled POST-HOC.\n\n**`research/qc/tailfmt.js`.** Extend the timing scrub to a clock time following a date, e.g. `\\b\\d{4}-\\d{2}-\\d{2}(?:[T ]\\d{2}:\\d{2}:\\d{2}(?:\\.\\d+)?Z?)?`. Then restamp the affected out-sha256 values under the existing normalize-migration procedure. The migration marker is visible in this fingerprint's `restamped:` line. I have not measured which other embedded tails print `[YYYY-MM-DD HH:MM:SS]` stamps.\n\n**`scanstat-t37-04-run.js`.** Record the five shard sha256 values in the fingerprint, or in the note's header, so that the combine step is bound to its inputs.\n\n## The gap that remains\n\n- **The T₃₇ moments are not independently recomputed.** A shard re-run is about 3.1 h single-threaded by the validator's projection; that suits a measure job, not this explore. The exhaustive G₂(37#) = 528 certificate rests on that run.\n- **No joint fit.** The seven-level joint post-hoc fit that `scanstat2.md` §6 refers to is not in the served record.\n- **Integration.** None of the proposals is applied.\n\n## Sources\n\n**primeoire public mirror**, `<project base>/docs/`, snapshot `main`, fetched 2026-09-11:\n\n- `research/history/staging/scanstat-t37-prereg.md`: §0 lines 23-45; §1 lines 75-108; §2 lines 110-132; §3 lines 134-177; §4 lines 179-210; §7 lines 258-275.\n- `research/history/staging/scanstat-t37.md`: ledger; lines 11-62.\n- `research/history/staging/scanstat2.md`: ledger; lines 92-141 and 320-321.\n- `research/OUTCOMES.md`: line 2810.\n- `research/scanstat-t37-04-run.js` (sha256 4dd628370d0d2f6dabecfcaa43c1b461589c1bf2ec9d229992bf3a3f598d7d90): code lines 23-152; fingerprint lines 225-236; embedded body.\n- `research/scanstat-t37-02-validate.js`: embedded OUTPUT, file lines 110-175.\n- `research/scanstat-t37-01-engine.js`, `research/import-scanstat-03-prereg.js`, `research/import-scanstat-04-score.js`, `research/exact-g2-ladder.js`: the driver's dependencies, run unmodified.\n- `research/t37-partials/t37-shard-37-{0..4}-of-5.json`: sha256 as in F3.\n- `research/t37-partials/t37-run.log`: first and last lines.\n- `research/qc/tailfmt.js`: `VOLATILE`, lines 62-93.\n- `research/qc/embed.js`: lines 41, 159, 428.\n- `research/qc.js` and `research/qc/`: the `embeds` check.\n\nNo local-only sources.\n\n**Builds on** return #59 (this session).\n\n**Channel.** Claim msg 205, found msg 212 (`formalize`).\n\n**Transcript scrub.** Kept only the lines from the GET /start that delivered this job onward.
