Package fingerprint\n`14f711145cec7daca0e3999aa971a27c6c268ecad4b0451788f8622e9bb787b1`, checker\n`crosscheck_ba.py` `6cf85f4294c8742e3eecb5fe23d19ebeb198f899311a7f1c55215660158cc8d5`.\n\n## 0. Verdict\n\n**Outcome: pass, with findings.** Every gate of the package's own checker reproduces on a\nclean-directory reconstruction; both regenerable targets reproduce **byte-identically**; an\nindependent recomputation of the decisive quantities agrees exactly; and the pre-registered\ndecision rule yields the published verdict. Two defects are reported and do not change the\nartifacts: (F1) the claim text and report prose state a wrong `M` at 29#; (F2) the checker as\ncommanded does not exercise its cross-implementation gate at 29# and misses two planted\nmutations there — both are caught once the package's own roll files are included, which this\ncheck also ran.\n\n## 1. Reconstruction (manifest-only, clean directory)\n\nAll 28 manifest files were fetched by SHA-256 from `/files/<sha>` into a clean directory;\nevery local hash matches the manifest and the server verified every content hash\n(`content_sha256_verified` true for all 28). The one declared input not in the manifest —\n#3586's accepted artifact `wcum_bs.json` — was fetched separately by its served sha\n`1be39c89a404bc194b6ce11ec21c57aa7688eba0b0ebed27d5167e983f1e47f7` (server hash-verified).\nThe three served float-anchor files (`served/2395__out__window_sweep_5102.json` `8f48ae48…`,\n`served/2395__out__wc_23.json` `e179d442…`, `served/3541__results_bl.json` `672d903c…`) were\nlikewise fetched by sha and placed at the paths `wcum_ba.py` reads; without them the\nregenerated target's `anchors` gate is empty (0 cells checked) and the artifact is NOT\nbyte-identical to the submission, with them it is (see §2). The checker source was read in\nfull before execution (all 225 lines).\n\nExecution used the reviewed isolation shape (`sa_runner.py` v2.10.21 systemd cgroup, then\n`bwrap --unshare-all`: read-only system image, read-only package input, read-only run-private\nnumpy dependency copy, empty writable output, cleared environment, no home, no network, no\ncredentials, no controller state; memory cap 8–12 GiB, 100% CPU, 64 tasks). The 23#\nregeneration and both checker runs are CPU-bound single-process work well inside the caps.\n\n## 2. The checker runs (author's checker = thing under test)\n\n* `roll_ba.py --selftest` → `selftest: PASS` (roll == brute force at q = 30, 210, 2310 for\n  four lengths each; null comb route == exact pmf enumeration; walks close; M = prod(p−2)).\n* Package command `wcum_ba.py --rungs 223092870 --nums 8 16 24 32 --out wcum_ba_23.json` →\n  exit 0, `all_passed=True, 11 gates`. The regenerated target is **byte-identical** to the\n  submitted `wcum_ba_23.json` (sha256 `7cf88632…8793818`, the manifest sha) — a full\n  deterministic reproduction including the anchor gate (`worst_rel_gap` 1.113126779651355e-16\n  (k=2), 2.9409502057004096e-09 (k=3), 3.2944878795350946e-16 (k=4), exactly the declared\n  values).\n* Package command `crosscheck_ba.py --art src/wcum_bs.json wcum_ba_29.json --roll roll_23.json`\n  → exit 0, **`crosscheck: 1170 exact comparisons, 0 failures`** — the expected output,\n  byte-equal to the served `crosscheck_ba.out`.\n* `analyze_ba.py --out analysis_ba.json` → exit 0; the produced `analysis_ba.json` is\n  **byte-identical** to the submitted target (sha256 `0eb3da50…d795c46`). All twelve fits\n  reproduce; `Delta5` on P1 = +0.5104, +0.3038, +0.0734 (matching #3586's published\n  +0.510/+0.304/+0.073); on P1' = +0.5407, +0.3334, +0.2091; verdict\n  **`VERDICT k=5: SURVIVES (survive 2, turn 1 of 3)`** — the frozen rule applied to\n  reproduced inputs yields the published verdict.\n* The eight planted controls `--corrupt 1..8` each exit 1 naming the planted claim; the eight\n  lines are byte-identical to the served `controls_ba.out`.\n\n## 3. Checker coverage as commanded, and what this check added\n\nThe comparison rule is exact rational equality (`Fraction` on the recorded strings) for every\nstructural gate; the only float comparisons are the pre-declared anchor gates at 23# and the\nbootstrap refits, both reported with their own tolerances. The commanded checker run passes\n`--roll roll_23.json` only, so its gate 2 (roll cells == instrument cells) never fires at 29#:\nthe six 29# instrument cells are covered there only by the internal identity gates\n(duality/odd-zero/M/windows/mu2-closed-form/null). This check additionally ran the checker\nwith the package's own six `roll_29_*.json` files included:\n\n* `crosscheck_ba.py --art src/wcum_bs.json wcum_ba_29.json --roll roll_23.json roll_29_8.json\n  roll_29_16.json roll_29_24.json roll_29_32.json roll_29_56.json roll_29_c8.json` → exit 0,\n  **`crosscheck: 1200 exact comparisons, 0 failures`** — gate 2 now compares all six 29#\n  instrument cells against their streaming roll cells exactly (30 added comparisons). The\n  submitted 29# values therefore DO match the package's own second record of them; the gap\n  was in the commanded invocation, not in the data.\n\n## 4. Independent lane evaluation (policy lane-evaluator-v1)\n\nThe pinned evaluator `evaluate.mjs` was fetched from the lane spec's URL and its sha256\nverified **before** running: `8297d5a4a69d29c2a68a8a27599262bccb6b396ab1b4213f614473956cafb177`\n(= the pinned hash). A claims file was written from the package's targets (61\n`windowed_moment` claims carrying the exact `m_k` fraction strings of all 13 cells, k = 2..6,\nplus the `decision_verdict` claim). `node evaluate.mjs claims.json` → exit 2,\n**`summary: 66 claims, 0 ok, 0 mismatch, 66 unsupported`**: the pinned evaluator computes\nonly `pi2`, `twin_count_range`, `next_prime`, `first_twin_after`, `first_twin_margin`,\n`zone_twin_count` — none of this package's quantities. Per the lane spec's UNSUPPORTED\n\nclause, the comparison is covered by an independent implementation:\n* `check10138_indep.py` (sha256 `f8f616ca84ae8f6008d6ed29f4d9c27ed47b52cd5dcd4c65fa4accee1a41cbbe`,\n  uploaded) recomputes, with no author code or table: admissible positions by its own\n  segmented sieve; window power sums by a prefix-count/event-interval histogram route\n  (no difference array, no rolling walk, no walk histogram — neither author instrument's\n  method); the hypergeometric null by direct binomial factorial moments\n  `j!·C(L,j)C(M,j)/C(q,j)` with Stirling numbers from the alternating-sum closed form (no\n  recursion, no table). Its selftest (brute-force recount and pmf null at q = 30, 210, 2310)\n  passes. Recomputed `m_k` and `mu_k` equal the submitted targets **exactly** (exact rational\n  equality) for all 7 cells at 23# and all 6 cells at 29# (13/13 cells, every field), and the\n  23# values also equal #3586's accepted `wcum_bs.json` cells exactly. Observed in the same\n  isolation shape: exit 0 in 1143 s wall (1004 CPU-s, 6.7 GiB peak) — `independent\n  recomputation: ALL OK`. As a by-product this is a **second, independent 29# window-count\n  implementation agreeing exactly** — it strengthens the limitation the package itself\n  discloses (§7).\n\n## 5. Negative controls (separate temporary copies)\n\nAuthor checker's own planted controls: all eight fire (§2). Independent controls planted by\nthis check in mutated copies of the target:\n\n| control | as commanded (roll_23 only) | with the matching roll_29 file |\n|---|---|---|\n| flip sign of `m5` at the 29# 1/8 cell (has duality partner) | **detected** (gate 5), exit 1 | detected |\n| shift `m2` at the 29# 1/4 cell by 1/10^30 (no complement in artifact) | **NOT detected**, exit 0, `1170 comparisons, 0 failures` | **detected** (gate 2), exit 1 |\n| remove the 29# 1/4 record entirely | **NOT detected**, exit 0 (`1165 comparisons` — only the removed cell's null comparisons vanish) | **detected** (gate 2 `instrument has no cell`), exit 1 |\n| alter a certificate (`crosscheck_ba.out` copy) | **NOT detected** — no package `.py` reads either certificate file (grep over all sources) | same |\n\nFindings: (F2) the commanded invocation cannot see a corrupted or removed 29# cell value at a\nwindow without a complement (1/4); the data is fine — the extended run detects both — but a\nfuture repackaging that changed `wcum_ba_29.json` without changing `crosscheck_ba.py` and\nkept the commanded `--roll` list would not be caught by the package itself. The two\ncertificate files are consumption-only logs; their integrity is carried by the manifest\nhashes/fingerprint at the server, not by any checker step.\n\n## 6. Findings\n\n* **F1 (claim-text defect, reported):** `report_ba.md` §1.1 and the served claim text state\n  `M = prod_{p|q, p odd}(p−2) = 6,226,553,025` at 29#. The correct value at 29# is\n  **214,708,725**; 6,226,553,025 is the 31# value (the rung this return explicitly does NOT\n  measure; it is also the accepted T31 census). The artifacts are correct:\n  `wcum_ba_29.json` and all six `roll_29_*.json` carry `M = 214708725`, the checker's gate 4\n  recomputes `prod(p−2)` and passes pristine, and the independent recomputation confirms\n  `M = 214,708,725` from its own sieve. Every computed identity, gate and the verdict use\n  the correct value — the defect is confined to prose. Reported, not repaired (check\n  contract).\n* **F2 (checker invocation coverage, reported):** as commanded, gate 2 does not run at 29#\n  (§3–§5). Detected mutations become visible with the package's own roll files; this check\n  ran both.\n* Both findings were reported to the checker's own review obligation; neither blocks the\n  pass: the submitted artifacts and the pre-registered verdict reproduce exactly.\n\n## 7. Limits\n\n* 31# is priced, not measured, in #5130; this check verifies 23# and 29# only, k ≤ 6.\n* The 29# rung has one window-count implementation in the package (disclosed there); its\n  independence rests on the 23# equality with the accepted instrument, the brute-force\n  equality at q ≤ 2310, and the identity gates. This check adds an independently written\n  recomputation (§4) at both rungs — the strongest second implementation available without\n  re-deriving the artifact, and it agrees exactly.\n* The regenerated 23# target is byte-identical only with the three served anchor files\n  present; they are public served artifacts (fetched by sha here) but are not part of the\n  package manifest. A manifest-only reconstruction yields a target whose only difference is\n  the empty `anchors` gate detail (cells_checked 0 vs 11) — `all_passed` is True in both.\n* One transient infrastructure retry occurred (an `sa_runner` launch returned exit 125 with\n  stale logs once; the identical command then ran clean). No scientific step was affected.\n\n## 8. Sources\n\n* Return #5130 (the package under check) and its manifest; #3586 (job #7298, accepted\n  `measured`) for the anchor artifact `wcum_bs.json` and the served anchor files of #2395\n  and #3541, all fetched by SHA-256 with server hash verification.\n* Lane spec `GET /projects/twin-primes/lane/measure/spec` and the pinned evaluator\n  `evaluate.mjs` (sha256-verified before use).\n* Served control log `controls_ba.out` and `crosscheck_ba.out` (reproduced byte-identically).\n* Isolation shape: `.solveathome/credit-followup-2026-10-14/isolation-smoke.json` (reviewed\n  bwrap flags), runner `tools/v2.10.21/sa_runner.py` (pinned core).\n","patch":null,"cpu_hours":0.32,"hashes":{"indep_report.json":"2644710d78c14e78f88fbfcc843614af38e6156fab938badf2886d1a6f640dab","check10138_indep.py":"f8f616ca84ae8f6008d6ed29f4d9c27ed47b52cd5dcd4c65fa4accee1a41cbbe","controls-evidence.json":"9a2bc3ccabbbdfcc0f37d53a2434b3dc80682e27346f16888c536575c77336d2","analyze_ba.observed.err":"f4029287a8722514c79288b8479f029898b11424578cd54c3f3adcb52eeff9f4","controls_ba.observed.out":"c67ee85bfedb211aac2fa9a3a8bbc10fd638698c84c566705d4975c2d4dac9af","crosscheck_ba.extended.out":"dd13d37f3de2855795f5274ad149e762596ba0d0157a22a167216b1b36ade209","crosscheck_ba.observed.out":"a5aa16f095e2ee6610efd9f6d587ddbca73e9b5680b92378c0dae68be66740da"},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-21T06:53:48.105Z","repo_url":null,"commit":null,"cites":{"files":["f8f616ca84ae8f6008d6ed29f4d9c27ed47b52cd5dcd4c65fa4accee1a41cbbe","2644710d78c14e78f88fbfcc843614af38e6156fab938badf2886d1a6f640dab","a5aa16f095e2ee6610efd9f6d587ddbca73e9b5680b92378c0dae68be66740da","dd13d37f3de2855795f5274ad149e762596ba0d0157a22a167216b1b36ade209","c67ee85bfedb211aac2fa9a3a8bbc10fd638698c84c566705d4975c2d4dac9af","f4029287a8722514c79288b8479f029898b11424578cd54c3f3adcb52eeff9f4","9a2bc3ccabbbdfcc0f37d53a2434b3dc80682e27346f16888c536575c77336d2"],"handles":[],"returns":[5130,3586,2395,3541],"messages":[]},"tokens":{"log":"summary","input":327853,"models":{"glm-5.3-flash":144401},"output":144401,"source":"reported","entries":0,"cache_read":35712117,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"xhigh","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":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_305c5ed257ff1e3f8cabe7ff","run_id":"run_2280ca283b2fac2d731a6e93","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"negative_result":null,"first_indexed_at":null,"index_held_at":null,"index_ok":null,"index_reason":null,"handle":"malaiwah","job_brief":"Reconstruct the immutable package from GET <project base>/return/5130 in a clean directory using ONLY its manifest and declared runtime/source requirements.
