Folded accepted #5354** (the one accepted return since the last update; read in full). Its content\nwas already partly in v20 — v20 was written by #5355, which quotes it — so the fold-in here is the\n`through_return_id` advance to **5354** plus the corrections v20 still carried: the CMI figure\n(0.30 bit) is dropped, and the Z_x/twin/primes comparison is restated as one ordering.\n\n**2. Promoted the lane's one open unverified entry, 355** (source return **#5358**), after checking it\nagainst its source rather than against its prose. I re-derived every headline statistic myself, from\nthe source run's stored gap words (uint16, 4 + 1 words: twin-pair 1e7/1e8/1e9/1e10 and the ordinary\nprime-gap word 1e9), with my own implementation — no import of the author's `analyze_cw.py` or of\n#5354's `an.py`:\n\n| word | M | S1/S0 | rel2 | rel3 | rel3_2nd |\n|---|---|---|---|---|---|\n| twin 1e7 | 58,979 | 0.6459 | −0.19352 | +0.07228 | −0.12809 |\n| twin 1e8 | 440,311 | 0.6411 | −0.21244 | +0.10331 | −0.13331 |\n| twin 1e9 | 3,424,505 | 0.6484 | −0.21729 | +0.08829 | −0.14196 |\n| twin 1e10 | 27,412,678 | 0.6520 | −0.21560 | +0.08625 | −0.14348 |\n| primes 1e9 | 50,847,533 | 0.4665 | −0.19161 | +0.13212 | −0.11051 |\n\nAll 18 compared figures agree with #5358's table and with #5333's published prime row to 6·10⁻⁴\n(the printed 4 decimals match everywhere). The block-sd z also reproduces: −10.44 at 1e10, −8.83 at\n1e9 (20 blocks, `M_2` held at its global value). Instrument: `work/verify_355_cx.py`, output\n`work/verify_355_cx.json` (uploaded; sha256 in `hashes`), runtime 15.7 s on this 1-CPU container.\n\nSo entry 355's numbers are what its source says, and the two facts it adds are decision-grade for the\nlane: (i) the pair matrix over-predicts the twin word's lag-2 return by 27 % (M/S), between Z_x's 38 %\nand primes' 23.7 %; (ii) the second-order (triple) chain is *further* from the truth at lag 3 than the\npair matrix (−0.143 vs +0.086, and also further in absolute terms: 1.61e-3 vs 7.6e-4), so #5354's\n\"carry triples\" recommendation does not transfer to the real object. 27.5 % is 1/(1+rel2) = 1.2748.\n\n**3. Rewrote the Verified summary** (v21, 11,998 chars, five headings in order). Changes:\n- Best results: the gap-word line becomes `#5333,5354,5358` and carries the twin-word ladder, the\n  Z_x < twin < primes ordering on both statistics, and the `[recmp#10701]` marker for this check.\n- Dead ends: the \"don't compose A\" line gains the twin word and the worse-than-pair triple result,\n  and the CMI trap (\"needs a matched surrogate\" at ≥275 states).\n- Open questions: route 351's pre-registered band line is **replaced** — it has been run and produced\n  a split verdict (`rel2` half passes, `|rel3| ≤ 0.05` fails, the `rel3 ≥ +0.10` falsifier does not\n  fire) — by the split, #5354's unanswered \"no derivation of −0.28/−0.216\", and route 351's own next\n  step (held-out split of the stored 1e10 word, no new sieve).\n\n**Disclosed reductions** (the cap is 12000 chars and v20 was already 11,997, so the fold-in had to be\npaid for; nothing was cut to make room for prose):\n- The `VERIF#4531` best-results line (28 targets: 20 exact / 6 differ / 2 absent; reachable\n  674/fetched 673/accepted 448) is compressed away. It is a document-ancestry/ledger audit, not a\n  lane mathematical claim; #4531 is still cited in Open questions (`rt246#4531: ledger/regen incl\n  #3880`), and the itemised numbers stay in that return.\n- The CMI 0.30-bit figure is dropped because #5358 §5 shows the plug-in CMI at this alphabet size is\n  estimator-bias dominated (a true first-order surrogate reports 0.20–0.78 bits); keeping a number\n  the lane must not compare would mislead.\n- Wording compressions only elsewhere (leading zeros, \"vs\" → \"/\", article removal). The check\n  `work/check_summary_v21_cx.py` proves that every `#id`, `rt` tag, F-code and numeric literal of v20\n  survives except the two disclosed items above and the answered band endpoints (−0.32/−0.20), which\n  are quoted in #5358 §1.\n\n**Decisions on entries:** promote `[355]`; nothing rejected (no rejected returns are listed for this\nlane); `through_return_id` **5354**.\n\n## Checks run\n- `work/build_summary_v21_cx.py` — reproducible edit list v20 -> v21, refuses if any anchor is missing\n  or the result exceeds 12000 chars; ends at 11,998.\n- `work/check_summary_v21_cx.py` — headings present/once/in order; entity preservation; fold-in\n  present; answered open question absent; cap. Exit 0.\n- `work/verify_355_cx.py` -> `work/verify_355_cx.json` — independent recomputation, 5/5 words pass\n  every compared statistic; exit 0, run under `sah.py bounded` (process group cleared).\n- Publication path: `sah.py complete` preflight + scrub + final outbound scan; the summary, report and\n  transcript contain no credential, account/session/attempt identifier or local path.\n\n## Scope and unresolved obligations\n- This is a state-of-the-art rewrite, not a scientific verdict: the promoted entry's physics is\n  #5358's, at its own rung (measured, exact enumeration, one object, four heights); my addition is the\n  independent recomputation and the statement that the numbers match.\n- The lane's derivation of −0.28 / −0.216 / +0.086 is still missing; nothing here proposes one.\n- The CMI question stays open in the only usable form: a matched-surrogate comparison.\n- Compute: ~0.02 CPU-h (15.7 s recomputation + local text work), 0.01 GB disk.\n","patch":null,"cpu_hours":0.02,"hashes":{"verify_355_cx.json":"c5149d77977b5a785dea3fa63866fbabf2c2b4cbb7ed4a506f7edab55ebf771f"},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-22T03:00:02.086Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[5333,5354,5358],"messages":[]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"unmeasured":"codebuff/freebuff session record exposes no token counts for this assignment (no usage file, session DB or status output carries them; the session log is message-level only), so no count is asserted.
