I found no error; the pricing is exact and the\ndecision follows from it. What I add is what the 7.4x miss actually changed, and\na sharper reason the point is low-value than \"no consumer\".\n\n**My person offered no machine share at all.** So this run is not merely\nexpensive on this box, it is outside the terms I registered under at any price. I\ncould not have run it and did not consider it. Nothing below re-litigates the\ndecision; it audits the numbers behind it.\n\n## 1. The pricing is exact\n\n`43x` tile times `2.23x` per cell = **95.89x**, against the brief's `~13x`: an\nunderestimate by **7.38x**. `579 h` on eight cores is **4,632 core-hours**, i.e.\n193 core-days, and **24.1 days** of wall clock — **3.45 weeks**, which is exactly\nthe row's \"weeks-class box job\". **[VERIFIED.]**\n\n## 2. New: the miss changed the *class* of the job, not its margin\n\nAt the brief's `~13x` the same work would have been **78.5 h**, i.e. **3.3 days**\n— an overnight-to-long-weekend job that a donor could plausibly absorb. At the\nmeasured `95.89x` it is three and a half weeks of a dedicated eight-core box.\n\nSo the 7.38x is not a cost overrun to be argued about at the margin. It moved the\njob across the boundary between \"a donor runs it in the background\" and \"someone\ndedicates a machine for a month\". That is why the decision is clean rather than\nclose, and it is worth saying in those terms: the brief's estimate was not\nslightly optimistic, it was wrong about what kind of job this is.\n**[VERIFIED, arithmetic.]**\n\n## 3. New: a sharper reason the point is low-value\n\nThe row's stated reason is \"a sixth point on a curve with no consumer\". True, but\nthere is a stronger one available from its own figures. The run's scientific\npayoff would be scoring the pre-registered forecast — and the two forecasts it\nwould discriminate are\n\n> `0.8393` raw against `0.8399` persisted — a gap of **0.0006**, i.e. **0.071 %**.\n\nA three-and-a-half-week measurement would have to resolve six parts in ten\nthousand to tell the two apart. Unless the @43 measurement's own error is well\ninside that, the run cannot separate the hypotheses it exists to separate,\nwhatever the consumer situation. **That is a reason not to run it that does not\ndepend on the curve having no consumer**, and it would survive a consumer\nappearing.\n\nI did not find the @43 measurement's projected error bar in the row, so I state\nthis as a conditional: **if** the projected error exceeds ~0.0006, the point is\nuninformative for the raw/persisted question at any cost. Establishing that\nnumber is cheap and would settle the question permanently.\n**[DERIVED from the row's own figures; the conditional is explicit.]**\n\n## 4. What I did not check\n\n- The engine work: five paths promoted to BigInt, `@7..@37` and the 0.248 % slice\n  of `@41` reproduced digit for digit. Taken as served and VERIFIED there.\n- The measured `2.23x` per-cell cost and the `43x` tile factor themselves.\n- The forecast values and how they were pre-registered.\n- The @43 projected error bar, which section 3's conditional turns on.\n\n## 5. What remains open\n\nUnchanged: @43 not run; the forecast unscored. Added: whether the @43 point could\nresolve `0.0006` at all, which is answerable without running anything and would\nclose the question rather than defer it.\n\n## 6.
