{"id":67,"job_id":195,"problem_id":1,"lane_id":3,"type":"explore","user_id":1,"model":"claude-opus-5","provider":"anthropic","report_md":"# Job #195 (explore): `Q-zonegap-03-prereg` re-scored — the second pass was within the prereg, the \"0.195\" is not, and the derived engine checked at 1e11\n\n**Question.** `Q-zonegap-03-prereg`: \"What is Z2(p) in the unswept decade X in (1e11, 1e12]?\"\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- **The scoring note** is `research/history/staging/zonegap-03-score.md` (`Q-zonegap-03-score`, ANSWERED, HELD under the publication moratorium). Its verdict: all ten sealed rows HIT \"after a second pass added a band-edge argument to zonegap-01.js and re-ran the decade\".\n- **The foundation has a red team; the scoring does not.** `redteam-zonegap-foundation.md` covers `zonegap-01`. No adversarial pass on `zonegap-03-score.md` is in the served staging listing.\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- **INFERRED:** a deduction from read code.\n\n## Caveats first\n\n- **Scope of the run.** Nothing here re-runs the 1e12 sweep, which is about 70 min on an M1 Max per the note. The one computation is the check the note itself names as its first open falsifier (§6, D1): the scored derived engine run at X = 1e11. It took one core, 118 MiB and 1,247 s wall (0.33 CPU h), inside the 2-core / 4 GB share.\n- **Group T is custody, and I add nothing to it.** Four of its five hits are entailed by CUSTODY 1 and CUSTODY 3 passing, as the note's own caveat 2 and D6 say. The note says this plainly.\n- **Pooled-sd convention.** F3 takes the printed band \"±\" as the across-zone sd of c3, which is how the note describes it (§4). If the engine's ± were something else, F3's arithmetic would not apply.\n- **Conflict of interest.** My person owns the repo. Return #59 (this session) pointed here.\n\n## Findings, each with its rung and what would falsify it\n\n### F1. The second pass was permitted by the prereg's own wording\n\n**Rung:** REGISTER FACT.\n\n- **What worried me.** A producer change after the seal, followed by a re-sweep, followed by two rows that score only on that re-sweep, is the shape a pre-registration exists to forbid.\n- **What the prereg says.** It anticipated this.\n  - T5 (prereg lines 75-77): \"(zonegap-01.js hard-codes its band edges at e = 5, so a 1e12 run of THAT producer prints no [316228, 1e6) row; **these numbers score against whichever producer prints the band**, else through T4.)\"\n  - The scoring rule (lines 122-124): \"conditional rows (T5's new band) score only if a producer prints them.\"\n- **What the note did.** It added an additive, default-empty band argument, and passed the sealed interval `316228:1e6` as a literal (note §1-§2). The note's own falsifier table records \"the prereg's rules were not re-interpreted\" with \"none\". I agree on the text.\n- **One stretch of the wording.** S1 (the new-band head) is not written as conditional in the prereg. It scores only on the same printed X1 row, so it rides on T5's conditional clause.\n- **Falsifier.** A prereg clause forbidding post-seal producer changes. None exists; the prereg names \"whichever producer\".\n\n### F2. Every Group S deviation and band reproduces\n\n**Rung:** VERIFIED (arithmetic on printed values).\n\n| row | observed | sealed | deviation | in the sealed band |\n|---|---|---|---|---|\n| S1 | 0.723 | 0.7275 ± 0.0155, [0.681, 0.774] | −0.290σ | yes |\n| S2 | 0.7227 | 0.7259 ± 0.0101, [0.696, 0.756] | −0.317σ | yes |\n| S3 | 0.7506 | [0.7218, 0.90], guard < 1 | — | yes, guard holds |\n| S4 | 1,870,585,220 | 1,870,593,490 ± 26,264, [1,870,488,435, 1,870,698,545] | −8,270 = −0.315σ | yes |\n\n- **The note's own reading stands.** On S3, the 80% branch (\"stays 0.7218\") did not occur, and the 20% branch scored inside a wide band.\n- **The caveat that matters most.** S1, S2 and S4 all land about −0.3σ. The note says the sigma machinery is \"barely stressed\", and I agree.\n\n### F3. The note's \"pooled sd reads 0.195\" is not what the printed rows give; they give 0.193, the sealed value\n\n**Rung:** VERIFIED (arithmetic, with rounding bounds).\n\n- **What the note says.** §2, T5 clause 3: \"The pooled sd computed from the two ROUNDED printed sds reads 0.195 against the sealed 0.193 … it is left NOT PRINTED\".\n- **What the printed rows give.** Pooling the two printed sub-band rows — `1e5-p.5`: 17,701 zones, c3 = 3.930 ± 0.219; X1: 51,204 zones, c3 = 4.182 ± 0.132 — as a mixture:\n  - Zone-weighted mean: 4.11726, which matches the sealed 4.117.\n  - Pooled sd, √[(Σ nᵢ(sᵢ² + (mᵢ − M)²))/N]: **0.19337**. The sample-variance form gives the same to five decimals.\n  - Rounding interval, with each printed input moved ±0.0005: **[0.19272, 0.19402]**.\n- **The other three fields also reproduce:** 68,905 zones, mean u 0.80826, fraction u > 0.8 0.63143.\n- **Consequence.** The sealed 0.193 lies inside the interval, and 0.195 lies outside it. It also lies outside the two naive readings: the zone-weighted average of the sds is 0.154, and their rms is 0.159. So the sub-clause cannot be *scored* strictly from rounded inputs, because the interval spans 0.193 and 0.194. But the note's stated reason for leaving it open (a 0.195 reading) is an arithmetic slip, and the printed rows support the seal.\n- **Falsifier.** An engine definition of the band \"±\" that is not an across-zone sd, or a producer printing `[1e5, 1e6)` as one row with an sd other than 0.193.\n\n### F4. The derived-engine inertness check the note left open (D1), run at X = 1e11\n\n**Rung:** VERIFIED at X = 1e11 (see below). Inertness below record 42 is also INFERRED from the code.\n\n- **The check the note left open.** §6 D1: \"The stronger check — derived at X = 1e11 against `zonegap-01.js`'s bound tail, 315 s — was NOT run and is cheap\". Only X = 1e10 had been compared (guard (d), scrubbed sha256 `c81fce4d…`).\n- **Why it is not vacuous.** At X = 1e11 the 41-record construction equals `zonegap-01.js` byte for byte, so the test must use the **49-record** engine the 1e12 sweep actually ran. I rebuilt it with `zonegap-04`'s own construction (lines 198-251):\n  - guard (a): EXACT;\n  - guard (b): YES;\n  - its sha256 is 204fad50…, the scored run's derived-sha256 (F5).\n- **The run.** `node research/.zonegap-derived-rec49.js 1e11`, on the derived bytes unmodified, node v25.2.0, Apple M1, one process:\n  - exit 0;\n  - 1,247.3 s wall on a machine running other jobs (1,203.9 s user);\n  - 118 MiB maximum RSS.\n- **Result.** The normalised stdout (`tailfmt.normalize`) hashes to **2be031a1f75b1a3a6524ab7ee552d0846f2cac4b31fa74c6482dd7b06c997522**, the out-sha256 of `zonegap-01.js`'s bound 1e11 tail. Of 124 normalised lines, **0 differ**. So the scored engine prints, at 1e11, exactly what the custody engine's bound tail prints: CUSTODY 1 on records 1..41, the 27,292-zone sweep, and every band row.\n- **Why, from the code (INFERRED).** `zonegap-01.js` reads the record arrays in only three places:\n  - the filter `REC_START[i] + REC_GAP[i] + 2 <= X` (line 314);\n  - the envelope loop bounded by the zone bound (line 357);\n  - `REC_GAP.indexOf` of an attained Z2 (line 447).\n\n  For X below record 42's end (about 1.34e11) the added entries are unreachable.\n- **What this does not cover.** Inertness is now VERIFIED at X = 1e10 and 1e11, and INFERRED up to about 1.34e11. Above that, only the derived engine can run, so at 1e12 there is no second engine to compare against. The note says the same.\n- **Falsifier.** An X ≤ 1.34e11 where the normalised outputs of the two engines differ. There is none at the two points checked.\n\n### F5. The note quotes first-pass engine hashes; the scored second pass printed others\n\n**Rung:** REGISTER FACT, with the hashes VERIFIED.\n\n- **What the note quotes.** §1: \"Derived-engine sha256 `76b875a0...e0cb`; original `44b4e461...b82b`\". §6 D1 quotes `44b4e461...` and `76b875a0...` again.\n- **What the embedded second pass prints** (`zonegap-04-sweep-1e12.js` block lines 22 and 44): `zonegap-01.js file-sha256 8eb6a50a…` and `derived-sha256 204fad50…`.\n- **What the served files hash to.**\n  - The served `zonegap-01.js` hashes to 8eb6a50af2b501762a8c26b939725edc6b94aa044bb07ed9833deca9e4241a72.\n  - The 49-record engine rebuilt here with `zonegap-04`'s construction hashes to 204fad502aab9cf234a3b707ca9e9e7637d7afed840eedd1e40f36ae73e133cc.\n  - Both equal the second pass's values, so the served files are the ones the scored sweep used. The note's §1 and D1 text quote the first pass, whose engine predates the band argument.\n\n## Proposed text (not applied)\n\n**Ledger block, `zonegap-03-prereg.md`:**\n\n```\n<!-- ledger\nid: Q-zonegap-03-prereg\nstatus: ANSWERED\ntodo: none\nquestion: What is Z2(p) in the unswept decade X in (1e11, 1e12]?\nverdict: Sealed before any sweep past 1e11; scored in zonegap-03-score.md, where all ten sealed rows HIT at X = 1e12 (T5's new band and S1 on the second pass, which the prereg's \"whichever producer prints the band\" clause permits); Group T is custody promotion, Group S lands at -0.3 sigma, and the full-decade sd sub-clause pools to 0.193 (interval 0.1927-0.1940) from the printed rows.\n-->\n```\n\n**`zonegap-03-score.md` §2, T5 clause 3.** Replace \"reads 0.195\" with \"reads 0.1934 (rounding interval [0.1927, 0.1940], which contains the sealed 0.193)\".\n\n**`zonegap-03-score.md` §1 and D1.** Quote the second pass's hashes: `8eb6a50a…` original, `204fad50…` derived.\n\n**`zonegap-03-score.md` D1 and the falsifier table.** Record the X = 1e11 inertness result of F4.\n\n## The gap that remains\n\n- **Nothing here tests the 1e12 sweep itself.** Its figures rest on one embedded run plus in-engine custody.
