The d = 17 capped picture is closed and negative\n(#1869 recorded witness 3.5796230066864503; #1942 re-optimised 3.8115713687001214 < 1/A =\n3.8714672861014323, deficit ≈ 0.0598959174, `Q < 0`, whole-basis float ceiling 3.799–3.812 — exact\nanchor arithmetic re-verified, C03/C04; the setter's quoted 16-digit deficit reproduces to 3e-16).\n\nWhat the post-setter returns add is **scope and price**, not an answer:\n\n1. **The step's instrument is unaffected by the known defect.** #3850's `s = 0` stratum defect in\n   #1641's radial `violation_F2` is unreachable at k = 46: exactly, `22·(40/861) = 880/861 ≤\n   886/861 < 920/861 = 23·(40/861)`, so the `denominator_functionals` loop stops at `r = 22` and\n   every included `Δ` stratum has `s = 46 − r ≥ 24` (C08; #3989 and #3850 state the same). The\n   #1942 machinery the step reuses unchanged is safe at k = 46.\n2. **The step's budget is now known to be too small for its own recording pass.** #3887 measured the\n   uncapped d = 17 pair at ~43 µs/entry (6.0 s for 140 250 entries) and quotes #1869's cap-correction\n   recording pass at **27.1 worker-h for one `F_1²`** at d = 17 signature counts (7,655 / 220,672 /\n   45,293); the slot sets grow with n (374 → 568 → 846). A full d = 19 capped pair therefore exceeds\n   the step's own 4 CPU-h budget, and the pursuit should expect to land in the step's **own failure\n   clause** (record the exact resource point, the largest d completed, name the missing capability)\n   unless a cheaper partial probe is run. #3887's d = 19 2×2 probe is priced as **route 160's** next\n   step; it is not a substitute for route 234's step and does not replace it here.\n3. **The margin the cap must consume is now priced on the uncapped side.** #1599's uncapped d = 19\n   certificate prices the d = 19 uncapped margin over 1/A at only ≈ 1.07 % (`Q_{1/A} = +0.04141…`,\n   `I ≈ 1`; #1599's own words: \"uncapped margins over `1/A` of 1.06 %\"), while at d = 17 the cap\n   moved the optimum from the uncapped witness quotient 3.9013805276 (`J_0/I_0`, recorded) down to\n   the capped re-optimised 3.8115713687 — a consumption of 3.9013805 − 3.8115714 = **0.0898**\n   `M`-units on the exact re-optimised witness (3.9013805 − 3.812 = 0.0894 against the float\n   ceiling 3.799–3.812;\n   derived: arithmetic on recorded numbers, heuristic rung — the cap's consumption is not known to\n   be monotone in d). A capped crossing at d = 19 therefore requires the cap's optimum-consumption\n   to shrink by ≈ 2.2× under the enrichment — exactly what the step would measure first.\n4. **Any result must be quoted register-grade.** #4170's classification: a capped certificate must be\n   reported as `M^cap` with its distances to `1/A`, the anchors' midpoint `10166/2583` and `4`; the\n   d = 17 row fails both anchors (anchor-independent), and #1942's own review records that `M1^cap`\n   definiteness is \"neither shown nor refuted\" (near-kernel `I_cap ~ 3.2e-94`) — the review's\n   falsifier (a negative pivot in an exact `LDL^T` of `M1^cap`) still stands for d = 19.\n\n## Decision\n\nOutcome **`promising`**: the step is neither answered nor ill-posed, and no narrowing of its text is\nwarranted. `next_step` is the served step copied byte-for-byte (canonical sha `9d849528…a4f7`,\nequality asserted by C01/C14). `depends_on` = [1869, 1942] — the route's declared dependency set,\nunchanged from the setter. The held pursuit goes out with this note (items 1–4 above); these returns\nnever hold it again.\n\n## Scope, limits and disclosures\n\nComparison scope: the returns the assignment names (#4170, #4162, #3989, #3920, #3906, #3890, #3887,\n#3879, #3850, #3479, #3467, #2977, #2681, #2659), the setter #2607 and its route record, plus #1599,\nroute 156 and ask #13 fetched for the d = 19 provenance question. The brief states that additional\npotentially relevant results were omitted, so this check claims coverage of that set, not of the\nwhole project; an unlisted return computing the capped pair at d ≥ 19 would change the verdict. No\nexperiment was run and none of the cited returns' computations was reproduced; the only arithmetic\nhere is canonical-JSON hashing, sha256 inventory comparison, exact `Fraction` anchor/stratum\narithmetic on recorded constants, and context-scoped string scans over this run's own served\nsnapshots.
