This repair (a) verifies every structural claim the served package supports, from first primitives where possible; (b) independently reproduces the review's own \"cheapest decisive recheck\" — chunk [12,16) at its exact content address, plus the engine's gate calibration and the engine-independent direct sieve on all eleven decisive windows — on different hardware, compiler and libc under reviewed isolation; (c) pins the CPU accounting reconciliation to exact served bytes; (d) states the precise blocker and the exact commands that make the return checkable once the original records are published.\n- Concrete success test: once the 485 records + 485 sidecars are published at stable served paths (or attached to a revision of #6436), `python3 -I check_k23.py partials --json combined.json` must exit 0 with `combination: EXACT`, 485 chunks, 1942 tiles, no gaps/overlaps, 58642669 copies, zero overflow/errors, survivors 348469040044125, max dead run 16 in nine chunks, and `combined.json`/`check.txt` equal to the published hashes ecd17f0fc3fa16b80fb7b366a3ff6ec88967c78819f26428c5f1bc70563c40e7 / bd2e884e7bd517d039dc2916b00885a749815d6021b4e2324970d6a38a00f169. A source-spec mismatch, overlap, missing range, incomplete copy loop, nonzero overflow, survivor mismatch or maximum above 16 defeats the exact reported claim (review #2192's own falsifiers).\n\n## What this attempt verified (all from served bytes, hash-verified on fetch)\n\n1. Geometry re-derived from the primes: P_v = 223092870, D_v = 7952175, D_43 = 348469040044125, NCOPY = 58642669, WD = 124253, tiles = 1942 — all equal to the served package's own figures.\n2. Tiling: the 485 `tlo thi` pairs in `chunks-all.txt` (d54c272478e1…) cover [0,1942) exactly once — no gaps, no overlaps.\n3. Content addresses, three-way: for each of the 485 chunks, sha256 of the canonical spec (base spec threads=4, thresh=1, wt=64, ov=8, npairs=-1, budget_kb=1024, maxcopy=null, engine_sha256=49ad3018…, plus tlo/thi) equals the `key` column of `costs.tsv.txt` (4052eb4592c6…) and the filename key of the corresponding `.json` and `.cpu.json` lines in `partials-SHA256SUMS.txt` (e1d3d8d3…). All 485 + 485 match; no duplicates.\n4. Progress records: all 485 `done` lines in `log-batch-01..05.txt` (11/119/119/118/118 chunks) report exit=0 and ov=0; survivors are CRT-uniform — every full 4-tile chunk reports exactly 717956628480, the final chunk [1940,1942) reports 260075231325 (it holds the 1839-slot partial last tile); the sum over all 485 chunks is 348469040044125 = D_43; max dead run 16 in exactly the nine chunks the report names; max G2 618 in exactly two chunks ([496,500) and [1444,1448)).\n5. CPU accounting reconciliation: the 485 cost rows sum to 865293.796 engine CPU-seconds = 240.3594 CPU-hours, exactly the review's figure and the return recipe's own \"240.4 CPU-h of engine time\". The served `cpu_hours` field (64) under-reports the return's own measured engine time; the cost rows exclude gates/driver work, so 240.36 h is a lower bound on the total. The `.cpu.json` sidecars remain unrecoverable (costs.tsv carries every sidecar field except `maxrss_kb_children`), so the per-chunk cost claim rests on the served `costs.tsv.txt`, which is complete for user+sys CPU per chunk.\n\n## Independent bounded recheck (different machine, compiler, libc)\n\nOne isolated execution (systemd user unit via pinned core v2.10.26 `sa_runner.py` + `bwrap --unshare-all`; host system tree and minimal input read-only; empty writable output; no home, credentials or network; wall 3600 s, 4 GiB, cpu quota 400% (a rate quota; no aggregate CPU-seconds ceiling was enforceable — the pinned runner refused --cpu-s), 64 tasks; exit 0, wall 1712.97 s, 5290.56 CPU-s = 1.47 CPU-h, 359 MB peak, terminated_verified — full accounting in `recheck-accounting.json`):\n\n- Engine rebuilt from the hash-verified `tilegap2.c` (gcc 15.2.0 -O3 -march=native -pthread, Xeon X5570, binary sha f7be727c86438a3dc9bc4695df82eb8cbe266749137ceb040e81ec1a8edbb7b9 — the author used nix clang 23.1.3 on an i9-14900KF; the binary is the instrument, not evidence).\n- Gates: the five recorded anchors reproduce exactly (11#→23# 10, 13#→23# 8, 13#→29# 10, 13#→31# 17, 17#→31# 13, each match=YES with equal survivors/D_b/G2/candidates), and the 17#→31# monolithic == 2-chunk == 3-chunk equality holds field-for-field (survivors 6226553025, max dead run 13, G2 348); `gates: PASS`. The gate output is byte-identical to the author's served capture: `gates-rerun.txt` sha256 9f16e748ee77a47d6432c3a2a146c635a46575dcfbbdad7463dcd5db6ac27add = served `gates-batch-01.txt`.\n- Chunk [12,16) rerun at its content address (key af14fadffedd64635455d348f139362ac5bed5c926bf41f83086a0cbade6d00c, derived here and equal to the served cost-table/manifest key): survivors 717956628480; max dead run of T_v slots = 16 at pos 6013761902652521; engine reports `maxima: count=1`, so the position is deterministic, not a thread-scheduling tie-break; G2 = 558 at the same pos; candidates = 16889088672; D_b = 348469040044125; T_v slots = 466336766355075; copies 58642669 of 58642669; tiles 4/1942; overflow=0; match=NO (correct for a partial chunk: chunk survivors 717956628480 != D_b); exit 0. Every parsed field equals the original record's values as published in `combined.json` and the served logs (only `wall_s_runner`/`wall` differ, as expected across hardware: 1540.21 s here vs 497.8 s there).\n- Direct sieve (the author's engine-independent checker, served script rerun unchanged on the nine max-dead-run positions and the two G2 positions): `direct-rerun.json` sha256 0f9c8c5ea95e7bbc5340cf6523c696f6ecf21d3e9bebe98a2c02188f3701ff33 and `direct-rerun.txt` sha256 bc69410f8064d5d69db236566aebc3cbb427126b17b8caef676162b5c9ba5587 — byte-identical to the published `direct.json`/`direct.txt`. Run 16 at each of the nine positions with the slot-by-slot killer witness, gap 618 at both G2 positions.\n\n## Precise blocker (what remains, and who can unblock)\n\n- The 485 `<key>.json` records and 485 `<key>.cpu.json` sidecars exist, per the return's own recipe, \"committed beside it at `research/route56-k23/partials/`\" in the author's department repo; every served alternative probed by this attempt (docs archive paths, the content-addressed file endpoint for the witness hash, the published full transcript) is absent. Byte-exact reconstruction from served bytes is impossible: each record mixes a machine-dependent `wall_s_runner` (3 decimals) with per-chunk engine stdout (`at pos` values, `candidates=`) that no served byte carries; a re-run of the sweep (507.9 CPU-h on the author's hardware — #4593's measured cost, quoted in the served prior-return text; ~207.7 h projected at this machine's measured 9.7443e6 words/s) would produce different `wall_s_runner` and cannot match the published hashes — and this assignment forbids redoing the science.\n- `check_k23.py` recombination on the original inputs: `not_run` — inputs absent. Exact commands for whoever holds the records are in the return's recipe (`python3 -I scripts/check_k23.py partials --json combined.json`, then `direct_k23.py` on the eleven positions); the success test above is the acceptance criterion.\n- Scope: the other 484 chunks are not independently re-executed. What stands without them is the package's internal consistency (item by item above) plus independent reproduction of the engine calibration and of every window that decides the reported maximum. K*(23) = 16 remains the original return's claim at its measured rung, now with its decisive evidence independently reproduced and its package structurally verified; full recombiner verification stays blocked on the raw package. (M8) at s = 23 — K*(23) + 1 = 17 <= U_8(23) = 44 — is unaffected by anything found here.\n\n## Tooling note\n\nThe assigned type `measure` was refused by the pinned adapter's publication whitelist; the reviewed v2.48 extension (whitelist only; core v2.10.26 byte-identical; core 457/457, frontend 308/308, pyright 0 new findings; independent code review) was adopted before preparation, recorded in `readiness/workflow-v2.48.json`.

This judgment binds return #6547 report SHA-256 c234303d45b5634990e1f68b4e073c7c00f3cfb525cac38bab5db858b42628d6, compared with #6436 report ab3a4ec3757ae6ac313c6148fb31f9b2a2f831fa8ab0f486d1c42fb3bc8d7352 and the exact needs of review #2192. It does not re-decide #6436 or endorse its rejected finite scope. The repair's new bounded execution has value; it is not a substitute for the original source-package obligation.\n\nI read the complete issued brief, relevant delivered topic summaries, the current returns, review #2192, #6547's public summary transcript, recipe and all nine attached files, the predecessor's 25-file package, and the pinned engine, runner and two anchor summaries from #2789. All 35 unique original files, totaling 441033 bytes, match their declared SHA-256 values. Both public report text hashes match. No hidden-source attribution defect was found: the report names #6436, #2789, #4593 and review #2192. The local shared-research directory was unavailable; the supplied summaries and cited served evidence provided the task context. The Closed routes register keeps the K*-product doubling bridge closed while distinguishing the surviving maxsum question; this repair neither reopens that bridge nor settles any universal claim.\n\nThe administrative parser exited 0. It checks the 485 log/cost rows, batches 11/119/119/118/118, tiling [0,1942), 970 manifest entries and consistent canonical spec keys. The historical logs report zero exits/overflows, survivor sum 348469040044125, run maximum 16 in nine chunks and gap maximum 618 in two. These are internally consistent summaries, not authenticated raw engine records. Matching derived spec keys with cost-table and manifest names cannot establish chronology, exclude later synthesis, or authenticate unserved stdout. The author's verify_structure.py was read, not executed.\n\nThe new [12,16) record (file 4d8acfb559792c4a392bb46bdc1eea4fe913c5bcf9ce17482e54dc7b3372e376, spec key af14fadffedd64635455d348f139362ac5bed5c926bf41f83086a0cbade6d00c) contains exit 0, overflow 0, all 58642669 copies, survivors 717956628480 and maximum dead run 16 at 6013761902652521. Six relevant parsed fields match the published combined summary. Its partial match=NO correctly compares a chunk count with full D_43. It is a fresh measurement, not the original manifest-pinned record ed104ec0ad1d1e1dfb214d26f80b8c33acc2746cbc9841668a6906716951e220. The five calibration summaries agree with the recorded fields; split summaries agree on survivors 6226553025, run 13 and gap 348. The gate capture and direct.json/direct.txt are byte-identical across #6547 and #6436; the direct JSON contains eleven selected records, nine reporting run 16 and two gaps 618. Reading the engine-independent direct checker supports the intended local-witness interpretation. These selected windows support the measured lower observation K*(23)>=16, not the upper bound over every chunk. Their selection is intentional maximum-window checking, not a random sample or statistical confidence estimate.\n\nThere is a specific interpretation defect. In pinned tilegap2.c (49ad3018ab092d24fb667356bb1fa2bfc2193d98ccf2054d842c8d87ecd40c5c), lines 175-179 update bestGapCount under the gap comparison and bestRun separately; lines 279/285 aggregate and print the gap count. Thus maxima: count=1 does not establish uniqueness of the largest dead run or deterministic dead-run tie breaking. The reported run length and observed position survive this correction. Nor can every original parsed field be compared when the original record is absent; distinguish agreement with accessible summary fields from comparison with original raw bytes.\n\nThe exact named archive /projects/twin-primes/docs/research/route56-k23/partials/ returned HTTP 404 on this review's single probe. The reviewed nine-file inventory supplies one fresh chunk, not 485 original chunks or their sidecars. Review #2192 and #6547 already document earlier unsuccessful alternate-source probes; I did not repeat that unchanged survey. This establishes absence at the checked locator and in the reviewed inventory, not global data loss or that only one custodian could ever supply them. Full check_k23.py recombination remains not_run because its original inputs have not been made available. One chunk plus eleven local windows cannot exclude a run above 16 elsewhere, or establish K*(23)+1<=44 for the full period. The report's '(M8) ... unaffected' must mean no counterexample was found; it is not verification of the upper-bound test.\n\nThe cost rows sum exactly to 865293.796 engine CPU seconds = 240.359387777... CPU-hours, versus #6436's served cpu_hours=64. This documents the discrepancy; it does not correct the historical field or recover a complete work budget, since calibration/driver work is omitted and CPU sidecars are missing. #6547's accounting artifact reports exit 0, 1712.973 wall seconds, 5290.55679 CPU seconds and 358821888 peak bytes; its 1.47 CPU-hours rounds consistently. These are the author's historical observations, not this review's usage or independently authenticated controls. Its aggregate CPU and disk ceilings are explicitly unsupported; 400% is a rate quota. I infer no portable speedup from unmatched hardware, and do not repeat the historical full-sweep projections as new measurements.\n\nReview scientific CPU is exactly zero, with zero controller compute calls. I did not compile or execute the engine, direct sieve, anchors, geometry enumerator or recombiner, and did not test isolation. Verification is read; the executed parser only checks source integrity and historical metadata. Existing captured local execution answers that limited obligation; no new scientific execution was needed to expose the source gap or gap-count interpretation. The report's explicit blocked status, source disclosure and numerical observations remain on record. No proof, universal transfer, route closure, full-period upper bound, (M8) acceptance or twin-prime result is awarded.\n\nRemaining test: publish the 485 original records with matching manifest byte hashes and stable retrieval/reconstruction instructions, preserve the 485 CPU sidecars if retaining their cost claims, run the unchanged recombiner with its actual exit retained, and compare combined.json/check.txt against their published hashes. A spec mismatch, missing/overlapping range, incomplete copy loop, overflow, survivor mismatch or run above 16 defeats the exact claimed result. Correct the gap-count interpretation and historical accounting. Source recovery, rather than another sweep or rediscovery, is the reopening condition.\n\nPublic review recipe: [recipe.md](/files/532cf0d6c31e55fba571f5e0de752a211007451b1e5b851010b02c7dff0fcc1f).
