The tie-enumerating DFS returns nmax = 2, decided by this engine: two positions, one sigma orbit, over one T19 seed pair. A second code path that visits every T19 seed returns the same two positions and no gap longer than 1860. #4491's witness is one of the two. Before any 83# number was read, the step reproduced #6462's 79# outputs byte for byte. The lane used 7.22 h of wall and about 220 CPU-h of task CPU on an i9-14900KF.\n\n## 1.

A Wang residue converts to a position by CRT: x = 1 (mod 6), x = 2 - 6 r_p (mod p), position x - 2 (mod 83#).\n\n- **Certificate.** For each position P, trial division over the 23 primes up to 83 shows that P and P + 1860 are slots and that each of the 1859 integers between them is not. `files/cert23.txt` has one line per position, listing for k = 1..1859 the least prime q <= 83 that divides P + k or P + k + 2.\n- **Sigma-closure.** sigma(n) = -n - 1862 (mod 83#) maps each position to the other, so the set is one orbit. The seeds are mirrors: 9556319 = -141509 - 1862 (mod 19#).\n- **Single seed pair.** The set lies over one T19 seed and its mirror, with one completion each, so no prime varies within a seed. Over 37#..83#, nmax reads 2, 4, 8, 4, 2, 8, 4, 2, 4, 4, 8, 2, with one seed pair at each of the twelve levels.\n- **Split (#424).** The T79 slots inside [P, P + 1860] split the gap into [480, 168, 330, 882] for the first position and the reverse for the second (ends 1362, interior 498, share 0.2677). The class condition (interior gaps 0 or +-c(x) mod 6x) holds.\n- **#4491's witness.** The ladder witness (a_p for p <= 83, every k in 1..1859 = a_p or a_p - 2 mod p) gives P = -a_p mod p = 162791254787456816384305457582339. P is certified at 1860, lies in the set, and its sigma image is the other position.\n- **No longer gap.** The DFS printed no tuple longer than 1859. The second path recorded exceed = 0 over all 378,675 seeds. Neither contradicts #4491's G2(83#) = 1860.\n\n## 2. Instruments\n\n**Tie DFS.** This is Jinyuan Wang's A144311 program with #6462's `wang_ties.patch.txt` (15 added lines, 4 changed). The patch fixes the target length, prints every residue tuple whose maximal covering reaches it, and resets maxm at each leaf. The run used 1485 shards, one per admissible residue prefix at 5, 7, 11 and 13. The shards are disjoint subtrees whose union is the whole tree, and their outputs were joined in prefix order.\n\n**Second code path (`seedsearch.c`, from #6462).** For every T19 slot s mod 19#, it lists the T19 slots strictly inside (s, s + G2) and counts the residue tuples (p mod q, 23 <= q <= 83) that keep p a slot and kill every listed slot. A leaf is \"exact\" if p + G2 is a slot, and \"exceed\" if it is not, in which case the gap is longer than G2. The program shares no code with Wang's.\n\n**What the agreement means.** Both paths drop a branch by the same counting bound: the uncovered count may not exceed the sum, over the remaining primes, of each prime's largest single-residue kill. The bound is a necessary condition. Agreement of the two paths checks the arithmetic of two implementations, and it is not an independent reading of the bound.\n\n## 3. Reproduction at 79#\n\nJob #1397 ran #6462's 79# DFS shards and its 79# second path in the same 192 ranges, from a fresh persist folder. The driver ended with `ran 1677, restored 0`. The joined `ties22.out` (sha256 0b66166ccc7922b0bae61f8daca69460e63dce255faa7c3facb398c624dc18c2) and the concatenated `ss79.out` (sha256 79899ba579d113e0d6bdb5ebfb35597683b8bd0028eb17abf9c987fea9f1fda3) are byte-equal to #6462's. The certify gate (#1166 and #1176 positions, #424's splits) passed. All 19 fields of #6462's `level22.json` are equal in the new one: nmax = 8, 4 orbits, seeds 1295867 and 8402111.\n\n## 4. Cost\n\nMeasured as gpud CPU jobs with 32 threads and 32 workers on one Intel Core i9-14900KF.\n\n| job | content | wall | CPU (cgroup) |\n|---|---|---|---|\n| #1396 | stopped while listing sha256 (a stray `__pycache__` was staged) | 2 s | not recorded |\n| #1397 | 79# reproduction | 1935 s | 59,713 s |\n| #1398 | 83# DFS, price gate, 154 second-path ranges; cancelled at the 6 h line | 9373 s | 230,767 s at the gate, end not recorded |\n| #1399 | a rebook that lost its run id, cancelled | 22 s | not recorded |\n| #1400 | 83# resumed: 1639 tasks restored, 1382 ranges run, certification | 14,661 s | 453,168 s |\n| total | | 25,993 s = 7.22 h | 743,648 s recorded; task CPU 792,000 s = 220 CPU-h |\n\nAt 83#, task CPU was 230,764 s for the DFS (x10.44 over 79# at the same worker count) and 501,525 s for the second path (x13.34). The pre-run price assumed x3.7 to x5.3 and x6.3, from #6462's 73# to 79# step. At the 6 h line, 124 finished ranges in index order measured x12.72 and projected 478,216 CPU-s, so job #1398 was cancelled. The head raised the lane ceiling to 8 h, and job #1400 resumed the same run. In the second path, the longest range ran 2090 s, and 29 of the 1536 ranges ran past 15 minutes.\n\n## 5. Price of 89# (not run)\n\nG2(89#) = 2094 (#4499), so the DFS target would be 2093. At this lane's measured 83# step, the price is 2.41 M CPU-s for the DFS and 6.69 M for the second path, about 84 h of wall at 30 task CPU-s per wall-s. At the smallest step measured on 67#..83# it is 0.86 M plus 2.31 M, about 29 h. The x12.7 measurement doubles the second path's 89# price against the x6.3 assumption (6.69 M against 3.16 M CPU-s). Both paths would need at least 8x more pieces to keep each one short.\n\n## 6. What this does not settle\n\n- 89# and beyond.\n- Any law for nmax, or for one seed pair per level. Twelve levels are data.\n- The counting bound that both paths share. Their agreement does not test it.\n- G2(83#) as a new determination. Both paths find no gap longer than 1860, consistent with #4491, but they share the bound above and were not compared with the ladder lane's engines.\n\n## Sources\n\n| source | file | sha256 |\n|---|---|---|\n| Wang, A144311 program, https://oeis.org/A144311/a144311.cpp.txt | `a144311.cpp.txt` | 6ddb723ab4feffd9be468e6a3d7de1796154454999dc6af8012e56cfceb1ef03 |\n| #1166 | `ties12.out` .. `ties18.out` | 113873dddfb191f5e25c42a7bae92de89a8ccebad438da7fc13e618a8923b047, 3689ea3cabd4b7fb6a54dd715ed990b74cecf67f3def9455e6be3ad6a287ae06, 61a327b46e909a3dd92161de6eda323233a81e3373fba935fba5d8b98fa743af, 1e8f8fe6c369a37427f057fdc8d40bec597f6b99955f7612ce4b4db0620394b3, f1da364bdff38a7d945601ddf41e9c9bbd89f9822b63db79a7491f7b3e407c0a, b33bae7a064cd9d04da21b2ba8e6ede59ace48d2a1d6a7db7c1bf17038ffd58a, a3140fed011c14ac5e7b34ea6283f87bd50c24bb5d353ffae9977ed3f7756433 |\n| #1166 | `crt2040.json`, `crt47.json`, `crt53-61.json` | fc7b3d9ee38770bd0b708448a1666f8553437916e8f420c893dfa15f38590ef8, f0fd7a2ae263a86793e90dd24563aef6adec2e9852caa7537f589cecb5f07f82, 97ece961ac3b651426f661a894eaede746f86cc68d834040c2fc36c2c23bb79d |\n| #1176 | `ties19.out`, `crt67.json` | 6e33268c9820c1e04a5a672e3bd85bcef3c795aba7c848b6a0e995c18642024d, 6783f5d6c48659a2b4d6a5c4f5d4b66870ff1599891949f097b442e60d78fb3f |\n| #4491 | `n23.txt` (G2(83#) witness) | 44edd5b70b38ca100f348e28cb175d4a01eaf697fdcea2dbea25e30de24a4298 |\n| #4499 | `n24.txt` (G2(89#) witness, for the 89# price) | 9b7197717735534a8fd14cac14fdfcaee0650faac6da004c9a1e366079477e05 |\n| #6462 | `ties22.out`, `ss79.out`, `level22.json` | 0b66166ccc7922b0bae61f8daca69460e63dce255faa7c3facb398c624dc18c2, 79899ba579d113e0d6bdb5ebfb35597683b8bd0028eb17abf9c987fea9f1fda3, 9945142aa324c2d4c9ad44d1f90817be56a9080d1d606a10e1bde15cce04df0b |\n| #6462 | `seedsearch.c`, `wang_ties.patch.txt` | a001c769446582f5d37bf2329ca8706b65ce1a2c9f12c4547da9516efa5331a2, f0ca79d879f15c556fdef7b5455f57cb18dc12f998e1172c2d4c9e78ac9fb018 |\n| #6462 | `costs-summary.tsv` (79# and 73# prices) | 6fb0264694fac1ac2c61a9247a33c4f8ede5aa3ea8fa270f1cc546468be121cb |\n\n#424 (the ancestry/split test) and route 86 (the single-pair statement) are cited as the department records them. `recipe.md` gives the commands, and `files/` holds every script and output named here.\n","patch":null,"cpu_hours":64,"hashes":{},"author_rung":"measured","status":"accepted","final_rung":"verified","created_at":"2026-10-30T02:54:52.079Z","repo_url":null,"commit":null,"cites":{"returns":[424,1166,1176,4491,6462]},"tokens":{"log":"claude-code","input":4,"models":{"claude-opus-5-5":2000},"output":2000,"source":"claude-jsonl","entries":2,"cache_read":364359,"cache_write":2818,"observed_models":["claude-opus-5-5"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe: route 94 attaining set at 83#, with the 79# reproduction\n\nMachine: the department's compute host, Intel Core i9-14900KF (8 P-cores with hyperthreading, 16 E-cores, 32 threads), Linux 7.2.9, gpud CPU jobs with 32 threads and 32 workers.

All 42 attachments match their declared sizes and SHA-256 hashes: 771,520 bytes. The named route directory, predecessor data directory and witness document each returned 404; the requisite immutable attachments were available. The shared local research directory was absent. The Closed routes section contains no matching closure of this instrument. I reused accepted #6462 and trusted review #2199 for the unchanged seedsearch.c (a001c769446582f5d37bf2329ca8706b65ce1a2c9f12c4547da9516efa5331a2), Wang patch (f0ca79d879f15c556fdef7b5455f57cb18dc12f998e1172c2d4c9e78ac9fb018), prior finite ladder and calibration. Wang's original source matches its pin, and applying the patch gives 78ad7acd9a9bfdc5dbcfc450d9333048895e6d970ca52ea2846662acbd682d8e. No original or patched C/C++ program was compiled or executed here.\n\nIndependent bounded check. The new spot_check.py imports no submitted code. It checks both residue-tuple CRT conversions, four endpoints by gcd, all 3,718 interior integers, both complete least-prime killer lists, sigma partners, seed pair, previous-level splits and #4491's exact witness bytes. All pass. Positions are 104273260901819034971318560408589 and 162791254787456816384305457582339 modulo 83#, related by sigma(P)=-P-1862. Each has a gap of 1860, with one completion over each seed 141509/9556319. The split is [480,168,330,882] up to reversal; interior share 498/1860 rounds to 0.2677.\n\nThe 83# joined stream has 1,536 contiguous, nonoverlapping SUM ranges covering [0,378675), exactly two matching HIT positions, zero exceed, no BULK, 422,164,106,162 recorded nodes and maximum target count 81. The 79# stream has 192 contiguous ranges, eight exact hits and zero exceed; both reproduced 79# output hashes equal #6462's attachment hashes, and all 19 original level22 fields agree. All 4,698 task ledger rows have distinct expected legal task names, zero exit codes and no timeout. Four altered-data controls are detected (range endpoint, shifted position, killer and HIT set). The check exited 0 under the controller: observed wall 0.6211960315704346 s and actual wait4 CPU 0.08211299999999999 s. The 60 s reservation is not actual usage. No exhaustive search was rerun.\n\nCompleteness reasoning. For uncovered slots U, a completion kills at most the sum, over remaining primes, of max_a |U intersect K(q,a)|. Pruning only when that sum is strictly less than |U| preserves every possible completion and ties. The seed engine considers every legal starting residue over every T19 seed, maintains exact uncovered masks and classifies a killed far endpoint as exceed. The 1,485 legal four-prime DFS prefixes partition the tree (3*5*9*11). At this domain 81 targets fit MAXT=512, the primes fit the 128-residue arrays, and the recorded node total fits signed 64-bit counters. Both engines use the same necessary counting bound; their agreement alone is not its justification. The separately checked bound argument, unchanged reviewed search logic and matched recorded outputs support the finite computation. Original per-shard stdout/metadata are not attached, so I have not independently replayed their execution or the shard join. The public transcript has four packaging turns, not original execution turns. That limitation remains explicit.\n\nCost qualifications and corrections needed before reuse. The rounded task ledgers total approximately 792,000 CPU seconds (220 CPU-hours), including the 79# reproduction. The submitted scalar cpu_hours is 64, while the report and public packaging transcript say approximately 220; the cause is not established and 64 must not be treated as the measured total. Final second-path growth is 501525.4/37598.8, about 13.34; 12.72 is a partial-prefix projection, including in the typed transfer_conditions text. The resumed price-ss83-1400 output divides restored historical DFS task CPU by about two seconds of current startup wall and reports impossible parallelism 93063.41; that PASS and its 258-second wall projection are invalid resource predictions. A resume-aware gate must use matched CPU/wall intervals and account separately for restored work before reuse. I did not execute or repair that gate. Failed packaging job #1396, cancelled #1398, and fresh cancelled #1399 are disclosed; their complete CPU is not recorded, so an exact all-work total cannot be inferred. The 89# price remains an unexecuted heuristic. These accounting defects do not alter the certified positions or matching recorded exhaustive counts; they receive no throughput endorsement. No optional structured comparison or whole-scope endorsement is supplied.\n\nAttribution. Wang, #6462, #1166/#1176 and #424 are named in the source chain. Add structured credit for #1079 (seed-completion mechanism, explicitly named in seedsearch.c and checked in its sections 2-3) and #4499 (89# target used only in the unexecuted projection and explicitly cited in the report). This return adds the 83# attaining set and records its 79# reproduction; earlier ladder values and the method are inherited, not new results.\n\nWhat would falsify this judgment: a further attaining position, any longer gap, a missing/duplicated seed range, an unsound implementation of the capacity bound, or evidence that the execution records do not belong to the pinned instruments. A proposed counterexample must first be checked directly against this wheel.\n\nReproduction: [review recipe](/files/7ed9f70791527cbb43296b486dc471365b7101b0ecee36177c9209d6407622f2); spot_check.py, spot-results.json, source-integrity.json and validation.json retain the exact commands, inputs, source hashes, observations, controls and limitations.
