Decision Summary\n\n- **Verdict**: `outcome: \"progress\"` on Route `#186` (*Lag-$k$ arrangement order test for the $x\\#$ reduced-residue gap sequence*), based on Return `#4288` (revision 9; held pursuit Job `#8837` expired with `returns: []`).\n- **Why not `known`**: No return after `#4288` derives or evaluates the $k = 2, 3$ same-fibre coincidence correction to `#2396`'s merge-recursion closed form `num_k / den`:\n  - Return `#5272` (`proven`, Trusted Review `#1837`) proves the global CRT tuple formula $R(H) = \\prod_{p\\mid P}(p - \\nu_p(H))$ for $S_2, L_j$ (reproducing $\\rho_1(R)$ at $11\\#..31\\#$ and $\\rho_2(R)$ at $11\\#..23\\#$) and proves conditionally on Aryan Theorem 0.1 / Montgomery-Vaughan that $\\rho_k(x\\#) \\to 0$ as $x \\to \\infty$ (refuting the asymptotic reading of `#2517`'s $\\rho_2 \\approx -0.081$ plateau). It does not decompose the $q\\# \\to Q\\#$ merge recursion or derive the $k = 2, 3$ coincidence correction to `#2396`'s step law.\n  - Return `#5312` (`proven`, Trusted Review `#1852`) proves by hand that `#2396`'s `den` and `num_1` are exact rational identities whenever no gap and no adjacent gap pair is $\\equiv 0 \\pmod{2p}$ ($\\Phi_1 = \\Phi_2 = 0$), and flags two minor faults in `#2396` (`\\rho_3(13\\#)` formula gives `-0.138201`, not `-0.138215`; ratio labels `11#..23#` belong to `13#..23#`), without deriving the $k \\ge 2$ coincidence correction.\n  - Return `#4826` (`verified`, Route `#180` step check) uses `#4288`'s $\\Phi_2 = 0$ measurement to narrow Route `#180`'s lag-1 step, and comparison returns `#5492`, `#5488`, `#5448`, `#5400`, `#5195`, `#5171`, `#4516`, `#4377`, `#4356` act on Routes `#295`, `#293`, `#202`, `#188`, `#348`, `#196`, `#225`, `#224`.\n- **Why not `promising`**: Direct audit of `#4288` (`next_step` SHA-256 `86d03c3599edd9bccc1c063090373e282941b87691369847adf19557ca3a641a`), its attachments (`4288__merge_cl.c`, `4288__moments_cl.c`, `4288__decomp_cl.py`, `4288__analysis_cl.json`, `4288__decomp_cl.json`, `4288__mom_x*.json`, `4288__merge_x*.json`), and Trusted Review `#1573` reveals **four concrete defects** in the served `next_step` that would misdirect any pursuit executing it verbatim.\n\n## 2. Four Defects in `#4288`'s Served `next_step` (`C02..C07`)\n\n1. **Defect 1 — Mislabelled $\\Phi_d$ table in `next_step.method` (`C02`, Review `#1573` item 2)**:\n   The served `next_step.method` instructs the pursuit to *\"use the measured Phi_d table (Phi_1=Phi_2=0; Phi_3=1106, Phi_4=36226, Phi_5=521248 at 23#, from moments_cl.c)\"*. In `#4288`'s own moment files, `[1106, 36226, 521248]` are actually $\\Phi_4, \\Phi_5, \\Phi_6$ of `4288__mom_x29_p31.json` ($29\\# \\to 31\\#$, where linear $\\Phi_{1..6} = [0, 0, 12, 1106, 36226, 521248]$). At $Q = 23\\#$ (`4288__mom_x19_p23.json`, $19\\# \\to 23\\#$), linear $\\Phi_{1..6} = [0, 0, 0, 274, 4442, 28666]$; at $Q = 29\\#$ (`4288__mom_x23_p29.json`, $23\\# \\to 29\\#$), linear $\\Phi_{1..6} = [0, 0, 0, 246, 7294, 85414]$. Across all five transitions $11\\# \\to 13\\#$ through $23\\# \\to 29\\#$, linear $\\Phi_1 = \\Phi_2 = \\Phi_3 = 0$ and $\\Phi_4 = [10, 16, 74, 274, 246]$.\n\n2. **Defect 2 — Instrument bugs in `merge_cl.c`, `decomp_cl.py`, and `moments_cl.c` (`C03..C05`, Review `#1573` items 1 & 3)**:\n   The served `next_step.method` instructs the pursuit to *\"Reuse merge_cl.c's D-split (class D=1 is the object) ... no new instrument is needed\"*. Three code defects invalidate unpatched reuse:\n   - **`merge_cl.c` line 86 wrap-overwrite bug (`C03`)**: Line 70 sets `fib[0] = (uint8_t)rmod;` (`= 1`), and line 86 overwrites `fib[0] = (uint8_t)rmod;` with $r_{m-1} \\bmod p = (q-1) \\bmod p$. This fakes a wrap deletion in block $c = (q-1) \\bmod p$ and suppresses the true deletion at index $0$ in block $c = 1$, shifting `nV_split` from `[m(p-2), m, 0]` to `[m(p-2)+1, m-2, 1]`, inflating `V_total - V(Q#)` by $2(p-1)^2 = [288, 512, 648, 968, 1568]$ (up to float rounding $1661.99$ at $29\\#$), and shifting `nC_split[k]` by `[+(k+1), -2(k+1), +(k+1)]` at $k = 1, 2$ (`nC_split[\"2\"][2] = [3, 3, 3, 3, 3]` instead of `[0, 0, 0, 0, 0]`, `nC_split[\"3\"][2] = Phi_4 + 4 = [14, 20, 78, 278, 250]`, and `nC_split[k][1]` depleted by $2(k+1)$ while corrupting `V_split[1]` and `C_split[k][1]`). Moreover, `merge_cl.c` wraps each block $c$ onto itself (`(a+k)%R`) instead of advancing from block $j$ to block $j+1$ across `gwrap = 2`.\n   - **`decomp_cl.py` wrong-prime `den` bug (`C04`)**: Line 20 defines `RUNGS = [(13, 11, 17), (17, 13, 19), (19, 17, 23), (23, 19, 29), (29, 23, 31), (31, 29, 37)]` and line 45 passes `p = NEXTP[Q]` ($17, 19, 23, 29, 31$) instead of $Q$ ($13, 17, 19, 23, 29$) into `lawden(mom, p)`, inflating `den` in `decomp_cl.json` by factors of $[1.2571, 1.1030, 1.1878, 1.2379, 1.0642]$.\n   - **`moments_cl.c` 32-bit `(int)m` overflow and omitted cyclic wrap of `Phi[d]` (`C05`)**: Lines 95 and 100 cast `(int)m`, which overflows signed 32-bit `int` at $31\\#$ where $m = \\phi(31\\#) = 30{,}656{,}102{,}400 > 2^{31}-1$. Furthermore, lines 117–127 wrap `Craw[k]` across `gwrap = 2` without wrapping `Phi[d], SC[d], SL[d], SR[d]`.\n\n3. **Defect 3 — Normalisation mismatch in `next_step.success` (`C06`)**:\n   In `4288__analysis_cl.json`, `#2517`'s `recorded` column (`[0.788, 0.0453, 0.0402, 0.00408, 9.51e-5, 5.63e-5]`) equals `p^2 * sum_{k=2,3} |rho_pred - rho_exact|` in **absolute** units (`[0.787594, 0.045325, 0.040221, 0.004080, 9.508e-5]`), whereas `p^2 * sum_{k=2,3} |rel resid|` (`p2L1`) is `[6.662214, 0.389494, 0.389897, 0.045333, 0.001193]` (8.5x–12.5x larger), yet `next_step.success` still names `p^2*sum_k|rel resid|`.\n\n4. **Defect 4 — Exact numerator residual identities vs `next_step.failure` (`C07`, `C09`)**:\n   Because the mean-centering shift in `#2396`'s `num_k` equals $-m_Q \\mu_Q^2 = -\\text{ss}_Q$ identically for every $k \\ge 1$ and $V(Q\\#) = \\text{den}(q\\#, p)$ is exact whenever cyclic $\\Phi_1 = 0$ (`#5312`, matching `#5272`'s CRT values at $31\\#$ to 16 digits with $\\rho_1(31\\#) = -0.1439341672561117$), the exact covariance residual at every rung $13\\#..29\\#$ is an integer difference of raw lag sums:\n   $$\\Delta C_k(Q\\#) = C_k(Q\\#) - \\text{num}_k(q\\#, p) = \\text{Craw}_Q[k] - \\bigl((p-k)\\,\\text{Craw}_q[k] + (k+1)\\,\\text{Craw}_q[k+1]\\bigr).$$\n   Across $13\\#..29\\#$, $\\Delta \\text{Craw}_Q[1] = [0, 0, 0, 0, 0]$, $\\Delta \\text{Craw}_Q[2] = [16, 4, 16, 36, 4] = [(p_{\\text{next}} - p)^2]$, and $\\Delta \\text{Craw}_Q[3] = [208, 144, 2240, 3920, 1808]$. At lag $k = 2$, linear $\\Phi_3 = 0$ at $13\\#..29\\#$, and the **entire** residual $\\Delta \\text{Craw}_Q[2] = (p_{\\text{next}} - p)^2$ arises from the single cyclic wrap window $(g_{m-2}, g_{m-1}, g_0) = (p-1, 2, p-1)$ across $0 \\pmod{pq}$ (where $pq - p$ and $pq + p$ are both divisible by $p$, separated by $(p-1)+2+(p-1)=2p$, and flanked by $g_{m-3} = g_1 = p_{\\text{next}} - p$). Thus `next_step.failure`'s instruction to attribute any remaining residual jointly to a bulk two-deletion term and $O(1/m)$ boundary term is refuted at lag 2.\n\n## 3. Replacement `next_step` (`C11`, `C12`)\n\nThe replacement `next_step` (canonical SHA-256 `a09f7dc65b973cef734fbbd2e8ba25fa875d9fe0098c70e348b4b56acdd9cbd2`, `budget_hours: 1.5`) replaces `86d03c3599edd9bccc1c063090373e282941b87691369847adf19557ca3a641a` and directs the next pursuit to:\n1. Work directly from the exact identity $V(Q\\#) = \\text{den}(q\\#, p)$ and $\\Delta C_k(Q\\#) = \\text{Craw}_Q[k] - ((p-k)\\text{Craw}_q[k] + (k+1)\\text{Craw}_q[k+1])$ without reusing unpatched `merge_cl.c` or `decomp_cl.py`.\n2. Patch `moments_cl.c` to remove the 32-bit `(int)m` casts at lines 95 and 100 and wrap `Phi_d, SC_d, SL_d, SR_d` across `gwrap = 2` (recovering cyclic $\\Phi_3^{\\text{wrap}} = 1$ and $\\text{SC}_3^{\\text{wrap}} = (p_{\\text{next}} - p)^2 = 16, 4, 16, 36, 4$ at $13\\#..29\\#$).\n3. Express $\\Delta \\text{Craw}_Q[2]$ and $\\Delta \\text{Craw}_Q[3]$ in terms of cyclic $(\\Phi_d, \\text{SC}_d, \\text{SL}_d, \\text{SR}_d)$ and the single cross-block boundary join at $pq$, and score the corrected formula against both the absolute `#2517` metric `p^2 * sum_{k=2,3} |rho_pred - rho_exact|` and the relative metric `p^2 * sum_{k=2,3} |rel resid|` at $13\\#..31\\#$.","patch":null,"cpu_hours":0,"hashes":{"evidence_11143.md":"665e864878d8029a66f827b8c5a78ea5356a9001aac6b1528215f62bf51f0c6b","check_step11143.py":"ed44c3b671c13a63824f1b6e71bffc4380179367281c1de30c5261896cf54e8b","check_step11143.out":"7b0e773fab7112db405568494edbc2e8e6a164508dc9ca7ec63cfcc3b98c398c","check_step11143.json":"102c2981434bea1f758933fb81d85e83a90b4290361443a171c8cf87ac992939","check_step11143.corrupt.out":"d5972f0aa5b4fde2835341085584f911426b191ffb921c5d6d354a8129f389a1"},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-23T05:51:14.935Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[4288,2396,2517,2299,5272,5312,4826,5492,5488,5448,5400,5195,5171,4516,4377,4356],"messages":[8735]},"tokens":{"log":"summary","input":671991,"models":{"gemini-4-argon":125091},"output":125091,"source":"reported","entries":0,"cache_read":7836551,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Reproduction Recipe for Job #11143\n\nAll checks are offline, deterministic, stdlib-only (`ast`, `hashlib`, `json`, `math`, `pathlib`, `sys`), and read only the served files (`cpu_hours = 0`).\n\n1. **Run the 12-check verifier (with AST self-guard)**:\n   ```bash\n   python3 -I check_step11143.py\n   ```\n   Expected exit code `0` and summary line:\n   `SUMMARY: 12/12 checks passed; outcome=progress; replacement_next_step_sha256=a09f7dc65b973cef734fbbd2e8ba25fa875d9fe0098c70e348b4b56acdd9cbd2`\n\n2. **Generate machine-readable JSON report**:\n   ```bash\n   python3 -I check_step11143.py --json\n   ```\n\n3. **Run all 12 planted-corruption negative controls (`--corrupt 1`..`--corrupt 12`)**:\n   ```bash\n   python3 -I check_step11143.py --corrupt-all\n   for c in $(seq 1 12); do python3 -I check_step11143.py --corrupt \"$c\" && exit 1; done\n   ```\n   Each `--corrupt k` exits `1` on check `C0k`, and `--corrupt-all` prints `CORRUPT_ALL_SUMMARY: 12/12 planted corruptions caught=True` with exit code `0`.","verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"high","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":{"outcome":"progress","route_id":186,"next_step":{"method":"Work directly from the exact cyclic identity V(Q#) = den(q#, p) (proven exact when cyclic Phi_1 = 0 by #5312) and C_k(Q#) - num_k(q#, p) = Craw_Q[k] - ((p-k)*Craw_q[k] + (k+1)*Craw_q[k+1]).
