Five values of (X̄−X(0))/S̄ are still not a law. The registry row is not stale and the question stays PARTIAL.\n\nWhat this adds:\n- a partial reproduction of the instrument;\n- exact rechecks of every figure of the note;\n- one incomplete table: R7 omits one cell, so R8 quotes a truncated sum. No conclusion moves.\n\n## 1. Verified: the instrument at @11, @13, @17, @19\n\nThe @23 level needs 5.69 GB, above this session's 4 GB share, so I did not run it.\n\n`research/natal-cap-35-x-multiplicity.js` with only its levels array changed to `[11,13,17,19]` ran in 78 s, peak RSS 335 MB, Node v25.2.0. Its four level sections are **line-for-line identical** to the embedded OUTPUT block's sections for @11, @13, @17 and @19 (52, 57, 59 and 53 lines), except the `[level time …]` tags. That includes (X̄−X(0))/S̄ = −0.2287, +0.0134, +0.1568, +0.2225 and the CHANNELS splits.\n\n*Rung: verified, at those four levels.* The @23 row is checked only through its printed numbers (§2).\n\n## 2. Exact rechecks from the printed @23 numbers (rung: proven arithmetic)\n\n- **The @23 row.**\n  - S_CRT/S̄ = 0.820157, S(0)/S̄ = 0.732440, X(0)/X̄ = 0.966103.\n  - (X̄−X(0))/S̄ = 0.265778, which prints as +0.2658.\n  - β = S(0)/S_CRT = 0.893048, and β·(S_CRT/S̄) = S(0)/S̄.\n- **§4 pre-registration.**\n  - Increments 0.2421, 0.1434, 0.0657; ratios 0.592, 0.458.\n  - lnW = 7.745, 10.310, 13.143, 16.088, 19.223.\n  - Slopes 0.09439, 0.05062, 0.02231; slope ratios 0.536, 0.441.\n  - The four continuations: 0.2526, 0.2458, 0.2533, 0.2478.\n- **R2.** Increment +0.0433; ratio 0.659; slope ratio 0.619.\n- **§6.**\n  - Independent-marginal relative error +0.0500%; the ensemble misses by 3.3897% of X̄; 3.39/0.050 ≈ 68.\n  - 1 − 28,379.29/175,886.83 = 83.9%.\n  - The two residuals sum to X(0) − X_indep = −3,092.06.\n- **§3.** 25 bytes × W(23) = 5.58 GB and × W(29) = 161.7 GB; 14400/18.9 ≈ 762.\n- **R7 shares.** 59.24/566.70 = 10.45% at @17 and 2576.56/10954.81 = 23.52% at @19, both from the embedded CHANNELS lines, which reproduce above. At @23: 175,886.83/216,803.55 = 81.13%.\n\n## 3. R7's cell table omits the k = K row, and R8 quotes the truncated sum (rung: proven, against the embedded block)\n\nThe note's R7 table lists k = 2…9. In exact arithmetic its k = 3…9 cells (k−1)·[A−E] sum to **−175,804.25**. But R7's own sentence, the instrument's CHANNELS line and the X-gap closure all use **m≥3 = −175,886.83**, and −40,916.72 − 175,886.83 = −216,803.55.\n\nThe difference, −82.58, is the row the table leaves out. The embedded block prints `1739 | 0 | 0.05 | 0.00 | NaN | -82.60`. That is the k = K = 1739 cell: the single rotation v = 0, where every scour prime divides, anchored 0 and ensemble 0.05, weight (K − 1). The same atom is −22.59 at @19 (`435 | 0 | 0.05`), inside that level's −2,576.56.\n\nConsequences:\n- **R8** \"At @23 they leave −175,804 of a −491,604 largest cell, 36%\" should read −175,887 (35.78%). The instrument's READINGS ADDENDUM A5, and its traceability line pointing at the note, repeat −175,804. The percentage and every conclusion are unchanged.\n- **R7's table** should carry the k = K row, or a note that the m≥3 total includes the v = 0 atom.\n\n**Falsifier.** The embedded @23 block not containing the k = 1739 row. It does.\n\n## 4. Checked and cleared\n\n- **The wrap.** `xchannel-triples.md` §2 reports a `Uint8Array` wrap (K = 435 → 179 at @19) that moved (X̄−X(0))/S̄ from 0.2225 to 0.2222. That was a draft of *that* note's instrument, caught by its reproduction gate. cap-35 carries the strike counts as `Uint16Array` (K = 1739 < 65536), and the @19 value 0.2225 reproduces above. The note's @19 point and its increments stand.\n- **Supersession.** `Q-xchannel-triples` (J decays 0.9025, 0.9599, 0.9659) and the closed-form, offset and @37 rows concern the joint deficit J, a different statistic. `xchannel-triples.md` R8 [INFERRED] reads the m≥3 migration as a marginal effect, not the joint deficit. None of `xchan-at29.md`, `xchannel-triples.md`, `item-x-offset.md` or `xchan-at37-score.md` prints a sixth point of (X̄−X(0))/S̄. The \"does the monotone rise hold\" half therefore rests on five points, as the row says.\n\n## 5. What remains open\n\n- A sixth point: @29 needs a streaming rewrite, since the per-slot array needs 162 GB.\n- σ_X and z-scores at @19 and @23.\n- The P1 census at @23 for this statistic.\n- The constant.\n\n## Channel\n\nClaim: msg 412, found: msg 426 (#g2-exponent).\n\n## Sources\n\nServed documents, snapshot `main`, no local-only sources:\n- `research/history/staging/xchannel-at23.md`: ledger, §§3–7.\n- `research/natal-cap-35-x-multiplicity.js`: embedded OUTPUT block (out-sha256 c14ab734…, streams stdout+stderr), @19 and @23 sections, READINGS ADDENDUM A5.\n- `research/history/staging/xchannel-triples.md` §2 (the wrap) and R8.\n- `xchan-at29.md`, `item-x-offset.md`, `xchan-at37-score.md` (grep only).\n- `research/QUESTIONS.md`: rows 217–223.\n\n## Transcript\n\nRemoved or redacted: the bearer token, platform and harness session ids, account and organisation identifiers, UUIDs, absolute local paths, the person's email, the contents of local memory, the local notebook and user-context reminders, and every line from earlier assignments (jobs #220, #233, #247, #258 and #271).\n","patch":null,"cpu_hours":0.02,"hashes":{},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-11T16:05:13.999Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[],"messages":[]},"tokens":{"log":"claude-code","input":256,"models":{"claude-opus-5":23934},"output":23934,"source":"claude-jsonl","entries":8,"cache_read":3933471,"cache_write":46868},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"1.
