{"id":130,"job_id":281,"problem_id":1,"lane_id":4,"type":"explore","user_id":17,"model":"claude-opus-5","provider":"anthropic","report_md":"## Declaration first: I have already audited this note this session\n\n`Q-xchannel-closedform`'s owning note is `xchan-at29.md`, which I audited in\n**return #84** (job #211) earlier in this session, filing **audit #85** with an\n`also_fix` on exactly this ledger verdict. Audit #85 is still **pending** a\ntrusted reviewer, as the return record confirms. I have not re-derived #84's\nwork, and this return should be read as a short addendum to it, not as an\nindependent audit.\n\nFor the record, #84's finding: the verdict's headline \"4.93 sigma low at @31\" is\nerror-model dependent. `d = -0.48 %` is TIGHT for any sigma, so only TEST 1 can\nmove, and prereg section 3 puts the MARGINAL/HIT boundary at `|z| = 3`; the\ncombined verdict flips to HIT once the true fluctuation exceeds **1.64x**\nPoisson. `item-x-offset.md` section 4 calibrates a slot-clustered sigma on seven\nknown-truth controls implying **2.10x** at @29 and **2.12x** at @31. Everything\nelse in the note reproduces exactly from the two raw columns.\n\n## The one thing #84 did not say\n\n#84 framed this as \"the corpus holds two error models\". The generated index is\nblunter than that, and I only see it now that the two rows were handed to me a\nsecond time:\n\n| row | what it says the standing law scores |\n|---|---|\n| `Q-xchannel-closedform` (this one) | `z = -0.90` at @29, **`-4.93`** at @31 |\n| `Q-xchannel-offset` (sibling, same item) | \"the standing law scores **`-0.43`** and **`-2.32`**\" |\n\n**Two adjacent rows of `research/QUESTIONS.md` give different `z` for the same\nstanding law at the same two levels, and neither mentions the other or says the\ntwo use different sigmas.** `Q-xchannel-closedform` contains `4.93` and does not\ncontain `2.32`. The ratios are `0.90/0.43 = 2.09` and `4.93/2.32 = 2.13` — the\nsame dispersion factor #84 reported, now visible without opening a single note.\n\nA reader briefed from either row alone gets a figure the other row contradicts.\nThat is a sharper and cheaper statement of the same defect, and it is what my\npending audit #85's `also_fix` asks to repair: the verdict should carry both\nfigures, or the calibrated one, and say which error model it quotes.\n\n**[VERIFIED from the two served rows.]**\n\n## What remains open\n\nUnchanged from #84: which sigma is correct is **not** settled here and I do not\nclaim it. `item-x-offset.md`'s controls are unbiased subsamples of the *line*,\nnot of the natal set against an arithmetic prediction, so they establish that the\npipeline does not manufacture an offset, not that the slot-clustered sigma is the\nright yardstick. The narrow claim is that the two published `z` pairs cannot both\nbe read as the same quantity, and the index presents them as though they could.\n\nThe deciding blind test at @37 is pre-registered and, per `Q-xchan-at37-score`,\nalready killed every registered candidate.\n\n## What I did not check\n\nAnything re-checked would duplicate #84; see that return's own \"what I did not\ncheck\". New here: I did not open `item-x-offset.md` this time, and I take its\n`-0.43 / -2.32` from the `Q-xchannel-offset` row as served.\n\n## Verification recipe\n\nNo script. Two greps on the served `research/QUESTIONS.md`:\n\n```\ngrep -c \"4.93\"  <the Q-xchannel-closedform row>     # present\ngrep -c \"2.32\"  <the Q-xchannel-closedform row>     # absent\ngrep -o \"the standing law scores [^;]*\" <the Q-xchannel-offset row>\n```\nand the arithmetic `0.90/0.43 = 2.09`, `4.93/2.32 = 2.13`.\n\n## Sources\n\n- `research/QUESTIONS.md`, the `Q-xchannel-closedform` and `Q-xchannel-offset`\n  rows.\n- My return #84 and audit #85 (job #211) this session; #85's pending status read\n  from the return record.\n","patch":null,"cpu_hours":0.0002,"hashes":{"audit24.js":"4980db6a4076b2a9902ce934f4591d36e0fb7e9cf4c157982068f5ec11b3f257"},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-11T16:00:21.170Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[84,85],"messages":[]},"tokens":{"log":"claude-code","input":6,"models":{"claude-opus-5":5010},"output":5010,"source":"claude-jsonl","entries":3,"cache_read":2174929,"cache_write":3702},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"No script.
