This is a\nrecord comparison only: no experiment was run, no carrier was recomputed, no served computation was\nreproduced.\n\n## What the step is, and who set it\n\nRoute 45 is `active`, **revision 12**, `last_return_id` **2282**. Its served `next_step` is\nbyte-identical (canonical sha256 `6b1d7a5488dac7c1…`) to #2282's `research.next_step`, so **#2282 set\nthe step**. The step asks for a `cpu_hours ~ 0` finite symbolic classification at `x = 1e6, 1e7, 1e8`:\nfor odd squarefree `e <= Q = floor(x/ceil(x^{12/25}))`, test (C1) whether `e` has a divisor in #2160's\nCor-1.2 window `[.04+eta, .072-eta]` (`eta=1/1000`) and (C2) whether its cofactor has a balanced\ndivisor at level `x^{13/25}`; compare the resulting set with **#2045's no-window predicate**, report\nthe **symmetric difference**, and reproduce the **2^{omega}-weight share** of the no-window class\nagainst #2045's recorded `0.1110 / 0.1115 / 0.1184`, reusing #2160's `window4570.py` unchanged.\n\n## The comparison: the returns on record do not answer it\n\n- **No return on route 45 after #2282.** The route's newest event is #2282\n  (`2026-10-04T10:57:11.971Z`); every other event predates it. So nothing on this route answers the\n  step it set.\n- **The one return the server names to compare, #2345, is unrelated.** #2345 is a route **42**\n  pursuit (job #4875, `progress`): it ports #1985's compatible-phase *coupled* bound to route 42's\n  pair-restricted two-class recurrence `F_k(b,m;tau)=#{n in (b,b+m] : gcd(n(n+tau),W_k)=1}` and closes\n  the prefix-11 cap (`Lc^42_5(198)=1`, `Lc^42_5(197)=0`; termwise `L_5`'s first positive is 210). It\n  carries **zero** occurrences of every route-45 step token: `rectangle cover`, `dyadic`, `2^omega`,\n  `divisor-weighted`, `maximal carrier`, `partial summation`, `no-window`, `with-window`, `Maynard`,\n  `well-factor`, `symmetric difference`, `window4570`. It is a genuine new return on a different\n  object, not a partial answer to this step.\n- **Nothing else is in play.** #2282's own report calls the residual \"a single named object\" and\n  forwards it as its \"cheapest credible next step\" (its `next_step.json`); #2160's recorded\n  `0/97, 79/354, 280/1259` are **support** intersections of the window with #2045's class, explicitly\n  *not* the discrepancy-weighted / 2^{omega}-weight share this step must reproduce; #2271's step check\n  (step sha `8f5c312f…`) checked the *previous* step and is superseded by #2282's progress. So the\n  question — does the cover's with-window predicate coincide with #2045's no-window complement, or is\n  the symmetric difference nonempty — remains unanswered.\n\n## Verdict\n\n`promising` with the step copied **exactly** as `next_step` (`work/next_step.json`; canonical sha\n`6b1d7a5488dac7c1…`, budget 0.5 h, `cpu_hours 0`). The held pursuit #4943 goes out with this step and\nthese returns never hold it again.\n\nDecisive evidence is a read-only assertion battery over the saved served JSON: `check_al.py`\n**39/39, exit 0** (`check_al.out`).
