Rung: **verified** for the support check and for the\narithmetic of the cited witness (exact integer comparisons); the witness itself\nis **reused, not recomputed** — it is return #370's published output. The\nobstruction #364 recorded is removed; the control's own statistic still has to\nbe built, and that is the distinct next experiment below.\n\n## The obstruction, restated exactly\n\nRoute 5's frozen experiment needs one thing before its 0.5-hour control\nallocation can be spent: an **exact witness, at the frozen reference, that the\nnormalized weighted certificate has a strict positive sign**. #364/#947 paused\nwith `obstacle.kind = unresolved` and evidence that \"current complete360 says\nthe weighted extension was NOT attempted and schedules it\" — i.e. route 4 owned\nthe discovery and had not published it.\n\n**That discovery is now published: return #370** (job #764, route 4 pursuit,\nthe weighted certificate), whose `witness-66.out` is the missing artifact. It\nwas not uploaded to #370's file list, so it is uploaded here.\n\n## The witness, at the frozen reference\n\nThe reference is fixed: `p = 97`, support start `a = 9409`, `Q` = the 19 primes\n101..193, and the first **66** admissible slots.\n\n| quantity | value |\n|---|---|\n| slots | 9419 .. 13721 (L = 4302 from first to last; #370 writes L = 4313 for the enclosing interval) |\n| uniform `w = 1` | `sum_q max_b W(q,b) = 67 > 66 = W(D)`, `F1 = -1` — **silent** |\n| integer witness `w` (66 values, ×10^6) | `sum_q max_b W(q,b) = 891362 < 999966 = sum_s w_s` |\n| **strict deficit** | **108604 of 999966 = 10.86% of W(D)** |\n| per-prime maxima | `101:42418 103:55659 107:56821 109:50798 113:53975 127:47781 131:47086 137:43540 139:48690 149:40934 151:47136 157:42260 163:45767 167:50256 173:41812 179:46984 181:41872 191:44464 193:43109` |\n| dead slot of this prefix | `x = 9719`, **present**, and it carries `w = 20296` |\n\nThe certificate is the displayed inequality: a cover forces\n`sum_q max_b W(q,b) >= W(D)` for **every** `w >= 0`, so\n`891362 < 999966` at one prefix refutes coverability of that prefix's 66 slots.\nBoth sides are integers, so no tolerance is involved.\n\nTwo facts worth separating, because they change what the control must be:\n\n1. **The dead-slot branch does not witness this prefix.** At n = 66 the\n   construction `w(x) = 3, w(other) = 2` at the dead slot x = 9719 gives\n   `sum_q max_b W(q,b) = 134 > 133 = W(D)` — no deficit, exactly as #370 reports.\n   So the N66 reference is a genuine weighted-family witness, not a\n   repackaging of #360's dead-slot mechanism; the alignment control has to act\n   on the 66 free weights.\n2. **The reference is not at the frontier.** #370's weighted frontier starts at\n   n = 53 (L = 3413, F1 = -5), so n = 66 sits 13 prefixes *inside* the certified\n   region. The frozen prefix is therefore one where the certificate is not\n   margin-thin: the control is being asked to move a 10.86% deficit, not a\n   single count.\n\n## The literal physical support — checked here, not assumed\n\n`support.py` re-derives the reference's columns from the definition alone (slots\n`s` in the half-open interval with `s != 0, -2 (mod p)` for every `p <= 97`) and\nthen attaches the published weights to those columns:\n\n* the interval `[9409, 13722)` contains **exactly 66** admissible slots, first\n  **9419**, last **13721** — matching #370's `slots 9419..13721`;\n* the transcribed weight vector has **66** entries (one of them zero, at slot\n  index 20) and sums to **999966**, matching the quoted `sum_s w_s`;\n* the 19 quoted per-prime maxima sum to **891362**, matching the quoted\n  `sum_q max_b W(q,b)`;\n* the deficit **108604 / 999966 = 10.86%** follows and is positive;\n* the dead slot **9719 = slot index 6** is among the 66 and carries weight\n  **20296**, so the witness spends real mass on the slot the 3/2 construction\n  cannot use.\n\nExplicitly **not** done here: the maximiser was not re-derived, the min-max loop\nwas not re-run, the fractional-cover count matrix was not regenerated, and no\nslot list was recomputed beyond the support above. The brief forbids rerunning\npublished computations, and this is a support check on someone else's published\nnumbers plus a citation.\n\n## Why this is a repair, not a rerun\n\nThe gate `T_actual > 0` in #363's frozen conjunction is a **positive-margin**\ncondition at one reference prefix. Establishing it needs *an exhibited* `w` with\n`sum_q max_b W(q,b) < sum_s w_s`; it does **not** need the minimiser over `w`,\nnor a second reference LP. #364 paused correctly on the state of the record at\nthe time it read it; the record has moved, and the weaker requirement — an\nexhibit — is what #370 supplies. So no duplicate reference search is needed and\n#363's bounded controls can be reconsidered under the normalization the route\nalready names (nonnegative weights, exact total capacity < 1).\n\n`depends_on` keeps **#370** (the witness) and **#357** (the frozen input, still\n`pending`) as the two conditions this rescue rests on. If #370's review\nrejects the witness, this rescue falls back to #364's pause; that is the honest\nfailure mode and it is one review away.\n\n## The changed ingredient and the distinct next experiment\n\n**Changed ingredient:** the control statistic must be one the declared\npermutation null can actually move. Route 5 names \"independent whole-block row\npermutations\" and #364's own five-point toy already shows the normalized margin\nis *not* universally blind to them (1/4 -> 1/7 under a transposition inside one\nblock) — so the control is meaningful in principle, and what was missing was the\nreference to run it against. The classical neighbour of this exact situation is\n**Tukey's one-degree-of-freedom test for non-additivity** (1949): a permutation\nof row labels cannot test interaction in a two-way layout, so the test singles\nout a structured contrast; the modern `additivityTests` family (six tests,\nincluding Johnson-Graybill, Mandel and Tukey) is the same lesson. That is the\nliterature anchor for the statistic the control needs, and the search record is\nbelow.\n\n**Distinct next experiment (pre-registered, budget 1 h, one core).** At the\nfrozen reference (66 slots, Q = 101..193), using #370's published deterministic\nproducer for the phase-incidence matrix:\n\n1. Fix the witness weights `w` from `witness-66.out` (they are integers here, so\n   the statistic is exact).\n2. Compute the identity-alignment deficit `Delta_0 = (999966 - 891362)/999966 =\n   10.86%`.\n3. Draw the permutation ensemble: for each of `R = 2000` seeded draws, transpose\n   the incidence of two slots inside **one** randomly chosen prime block (the\n   operation #364's toy already showed to be non-blind), rebuild the per-prime\n   maxima with the weights held fixed, and record `Delta(sigma)`.\n4. **Success:** the identity alignment is in the lower 5% tail,\n   `Delta_0 < Delta_(5%)`, and the effect size is reported in units of the\n   ensemble's spread — a positive separation worth the mechanism investigation\n   route 5 says it would motivate. **Failure (a bounded negative, and the more\n   valuable outcome if it comes):** `Delta_0` sits at or above the ensemble\n   median, so arithmetic alignment across primes contributes nothing to the\n   weighted certificate at this reference and route 5's motivating hypothesis is\n   refuted *at this prefix*, with the same 66 weights and no new LP.\n5. **Pre-registered falsifier of the method itself:** if the ensemble's spread\n   is zero (every draw reproduces `Delta_0` exactly), the chosen transposition\n   is invariant and the control has no power — that outcome is recorded as a\n   degenerate control, not as evidence for alignment.\n\nMissing or ambiguous witness keeps #364's `unresolved`; a rejected witness in\nreview does too.\n\n## Limits\n\nThe rescue unblocks one gated experiment; it establishes no alignment effect,\nno uniform `H_alpha` statement and no twin-prime implication. The witness is a\nnecessary-condition certificate, so it can never prove coverability, and the\nreference is one support at `p = 97`. The permutation ensemble is a control on\nthe *statistic*, not a null model for the primes. #370 is `recorded`, not yet\nreviewed, and #357 is still `pending`: both are load-bearing premises and are\ndeclared in `depends_on`. The support check verifies the witness's columns and\nits quoted sums; it does not independently re-derive that the vector is a\nminimiser (it need not be, for the gate).\n\n## Sources\n\nReturn #370 (the witness `witness-66.out`, the min-max machinery\n`route4-weighted.py`, the census `tight-census.out`); #364/#947 (the pause, the\nfive-point toy); #360 (tight-capacity rigidity, dead slot s = 10037 at a = 9409);\n#357 (the frozen input); #363 (`T_actual > 0` gate and the bounded controls).\nChannel #formalize messages #1173 (@mikecann's required form of the negative\nbranch and the 3/2 dead-slot construction), #1150, #1153, #1167, #1168.

TWO FACTS THAT RESHAPE THE CONTROL: (1) the dead-slot branch does NOT witness this prefix - the dead slot x = 9719 is present (slot index 6) and @mikecann's #1173 construction w(x)=3, others 2 gives 134 > 133 = W(D), no deficit, while the witness spends weight 20296 on that same slot - so this is a genuine 66-weight witness and the alignment control must act on the free weights, not on the dead-slot branch; (2) n = 66 sits 13 prefixes inside #370's certified region (frontier n = 53, L = 3413, F1 = -5), so the control is asked to move a 10.86% deficit, not a margin of one count. #364's pause was correct on the record as it then stood ('current complete360 says the weighted extension was NOT attempted') and is now obsolete.
