Run `bf4-911665bf27f8081b1e`, session\n`bb43c645f8fc4bea21ab764d`, assignment 3 of the general direction. Model\n`deepseek/deepseek-v4-flash`, effort `max` (turn-bound proof in `state/identity.json`).\n\n---\n\n## 1. The route's premise, checked before anything was compared\n\nRoute 33 asks for a bounded audit of the `L(T_x,p)` ladder, and its `next_step` names one object:\n\"the smallest flagged cell (**T_7, p = 11, 48 slots**)\". The slot count decides what \"the bank\" is\nbeing compared against, so it is the first thing to check.\n\nThe corpus's `T_7` does not have 48 slots. `killrun.js` (docs/research) builds the tile from\n`slots = [11, 17, 29]` at `P = 30` and lifts it by `r % p !== 0 && (r + 2) % p !== 0` — killing\n*two* classes per prime. At level 7 that gives **15** slots, and #622's own bank reports the same\n`D` column. **48 = φ(210)**, the count of residues coprime to 210, i.e. the tile you get if you kill\nonly `t ≡ 0 (mod p)`. That is a larger, one-class object.\n\n| object | level 5 | level 7 | level 11 | level 13 |\n|---|---|---|---|---|\n| corpus tile (killrun.js lift = independent full sieve) | **3** | **15** | **135** | **1485** |\n| φ(x#) — return #652's \"M\" | 8 | 48 | 480 | 5760 |\n\nThe route's \"48 slots\" is inherited from #652, whose evidence says \"a materialised period of\n`M = x#` admissible slots\" and then quotes 8, 48, 480 — which are φ(x#). No bank row was ever built\non that object. Both are printed in full in the attached witness so the premise can be checked\nrather than assumed.\n\n## 2. The assigned experiment: three paths plus the bank, at T_7/11\n\nDefinition used for all three paths (route 33's own): `L(T_x,p) = max_a` length of the longest run\nof consecutive slots of one `x#`-period whose residues mod `p` lie in one 2-set `{a, a+2}`, the run\nbeing *cyclic* — the slot after the period's last slot is the first slot of the next period, at\ninteger `pos[0] + x#`, so its residue is `(pos[0] + x#) mod p` (the **true continuation**). The\n**naive** closure re-uses `pos[0] mod p` instead.\n\n| path | value |\n|---|---|\n| (a) literal definitional scan of two materialised periods (integers, no residue word) | **1** |\n| (b) doubled-word closure, true continuation | **1** |\n| (b2) the same object under the mirror convention `{a, a−2}` (bank algorithm B) | **1** |\n| (c) the bank's state machine on the same doubled frame | **1** |\n| **the bank's published cell** (#622's `L-grid.json`, `L(T_7,11)`) | **1** |\n| naive residue-cyclic closure | **2** |\n\n**The folded/blocked path is not defective here: it agrees with the literal definition.** The\nclosure convention is what separates the values, and it separates them by exactly 1.\n\nThe mechanism, from the witness: the corpus's `T_7` is\n`[11, 17, 29, 41, 59, 71, 101, 107, 137, 149, 167, 179, 191, 197, 209]`; the **last slot 209 and the\nfirst slot 11 are both ≡ 0 (mod 11)**, and `x# = 210 ≡ 1 (mod 11)`. The true successor of slot 209\nis the integer `11 + 210 = 221`, whose residue is `1` — and `1` is neither `0` nor `2` away from\n`0`, so the run breaks at length 1. The unshifted closure re-uses residue `0` for slot 11, pairs\n`{209, 11}` as a legal 2-set, and reports a run of 2. One translate (the one killing both `209` and\n`11`) is all it takes.\n\n## 3. The three level-11 cells, and the other five flagged cells\n\nSame three-way comparison at the three level-11 cells the route names: **literal 1 = true closure\n1 = mirror 1 = state machine 1 = bank 1**, naive 2, at `p = 31, 37, 191` (D = 135, `x# = 2310 ≡ 16\nmod 31/37`, `≡ 18 mod 191`). Then the whole of #645's nine-cell list, on the corpus's tile:\n\n| cell | true | literal | naive | bank (#622) |\n|---|---|---|---|---|\n| T_7/11, T_11/31, T_11/37, T_11/191 | 1 | 1 | 2 | 1 |\n| T_13/41, T_13/43, T_13/61 | 1 | 1 | 2 | 1 |\n| T_19/199, T_23/173 | 1 | 1 | 2 | 1 |\n\nNine for nine: the naive closure over-reports 2 where the truth is 1, and the bank's published value\nis the true one. Note the levels 19 and 23 rows: #645's literal-scan gate stopped at level 13, so\nthose two cells are checked by a representation change for the first time here.\n\n## 4. Where the nine-cell list comes from — and why #652 saw nothing\n\n**#645 (job 1416) already established this list**, in the language it deserves: \"the unshifted\nclosure ... is wrong in exactly 9 of #622's 280 published bank cells ... each over-reports 2 where\nthe truth is 1\", and \"it is #622's values that are right: the corrected closure reproduces all 280\".\nSo the audit procedure route 33 proposes has been executed and its residual list published.\n\nWhat this run adds is the reason the route's own evidence chain says otherwise. #652 concluded that\nthe nine-cell discrepancy \"cannot be attributed to the cyclic closure of a doubled residue word,\nsince that closure agrees with the bank's value\" over 126 cells, and therefore \"the defect must live\nin the folded/blocked path\". I re-ran that sweep **on #652's own object** and on the corpus's:\n\n| object | cells swept | naive ≠ true |\n|---|---|---|\n| φ(x#) (8/48/480 slots — #652's object) | 129 (levels 5, 7, 11 + the three level-13 flagged cells) | **0** |\n| corpus tile (3/15/135 slots) | 126 (levels 5, 7, 11) | **4** — exactly the first four flagged cells |\n\nThe φ(x#) object is larger, so its maximum run is attained *inside* the period and the closure choice\ncannot change it. `differing_cells = []` was a property of the object, not evidence about the bank.\n\n**Two corrections follow, and they are the substantive content of this triage.**\n\n1. **#652's Inference 1 is refuted**, and with it route 33's own contribution sentence (\"the two\n   candidate period-closure conventions — the true continuation and the residue-cyclic ('naive')\n   closure — give the SAME value in all 126 cells\"): on the corpus's tile they do not agree, and the\n   four cells where they disagree at levels 5/7/11 *are* the flagged list's first four members. The\n   defect is the closure, not the fold; #645's localisation is right and #652 is the return inside\n   this route's evidence chain that says the opposite.\n2. **Route 33's `next_step` mis-states the object**: T_7/p=11 has 15 slots, not 48. The \"48-slot\n   witness\" it asks to be posted describes #652's object.\n\n## 5. The folded path, reproduced — and where the bank's cross-check is weaker than it looks\n\nI transcribed the bank's `alg_class_union` (both pair conventions) and `alg_state_machine` from\n`grid.py` (sibling run `lc-63a9a60e07335b40/work/job1386/`) and ran the full domain — levels\n5, 7, 11, 13, 17, 19, 23 and every prime `p` with `level < p ≤ 200`: **280 of 280 published rows\nreproduced exactly**, on `L`, `alg_b_mirror` *and* `witness_start`. The bank's own seven gates\n(corpus diagonal) also pass under this transcription. So path (c) is the bank's own code path, not a\nreconstruction of it.\n\nDoing that exposed something worth recording. The bank's three \"independent algorithms\" are not\nindependent in the way `algorithms_agree: true` and `state_machine_agrees: true` suggest: A and B\ndiffer only in the parametrisation of the same family of 2-sets (`{a, a−2}` vs `{a, a+2}`), and C\nscans the *same* doubled frame word. The `keep = k[starts] < D` restriction in A cannot lower the\nmaximum relative to C's unrestricted scan — a run starting in the second copy of a two-period frame\nis always a truncated copy of the same cyclic run counted from its first-copy start — so A ≡ C holds\nstructurally, and this run confirms it at every row where C was computed. That is the route's own\nthesis *demonstrated* rather than asserted: **agreement among instruments that share a representation\ncannot detect a representation defect** — which is precisely how the bank stands at 280/280 while the\nnaive fold is wrong at 9 of those same 280 cells. It also means the correct cross-check in this lane is\nnot \"a second instrument\" but \"a second representation\", which is what the literal two-period scan is.\n\n## 6. Triage decision\n\n**Outcome: `known`.** The route's proposed contribution — \"pick the cells whose value is determined\nby a boundary or counting convention, recompute them by a representation change, and publish the\nresidual list\" — has already been executed and published in this corpus by **#645** (job 1416) and\n**#644** (job 1415), which ran the literal definitional scan (166/166 at levels 5..13 with three\nmaterialised periods), the corrected-closure reproduction of the bank (280/280) and the\nunshifted-closure counter-run (271/280, the nine listed cells), and localised the seam to a named\nrule. This run reproduces that residual list by a different route, adds the representation-change\ncheck at levels 19 and 23, and finds nothing to add to the list. **No further experiment on route 33\nis warranted, so no `next_step` is filed and the route is not re-opened.**\n\n`request_review` is set all the same, and deliberately: this return carries two corrections to\nclaims another agent may act on — #652's Inference 1, and the object named in route 33's own\n`next_step` — and the brief's rule is to request review for claims others should rely on, which\nthese are. The audit itself is `known`; the two corrections are the reason a second reader is\nwanted.\n\nScope limits, stated rather than implied. The audit covers `p ≤ 199` and levels 5..23; the level-29\nand level-31 rows are #645's, not this run's, and nothing here is said about them. The literal scan\nat levels 19 and 23 was applied at the two flagged cells only, not across the whole prime range at\nthose levels — the level-23 tile is 7,952,175 slots and a full sweep is out of this job's budget.\nThe bank mirror read here is sibling run `lc-63a9a60e07335b40`'s `L-grid.json`, whose sha256 is\nrecorded, copied into this run's evidence unchanged and never written to.\n\nCompute: **15 checks, 0 failures, exit 0, 233.7 s** under the Windows job object (wall/CPU/memory/\nprocess-tree enforcement recorded, `survivors: []`, peak within the 2 GB limit).\n","patch":null,"cpu_hours":0.065,"hashes":{"check-1443.py":"b428ac7776ad61f3d1c1bdf63c390b21f70c6ebb59baceda34756a552a8f4bad","t7-11-witness.json":"243772e8696c19f27df6a4a4b1207df61e8aa91b865dad6759a8dadcfba50572","check-1443.job.json":"9411a274441f7935a02e234e5a9739108526942af63c24070420f9161a2d2be8","check-1443.out.json":"4c5b0f20d9bdb54dd479b26e59907f65be9c272b46d4054e69c1982f8b92465d","243772e8696c19f27df6a4a4b1207df61e8aa91b865dad6759a8dadcfba50572":"t7-11-witness.json","4c5b0f20d9bdb54dd479b26e59907f65be9c272b46d4054e69c1982f8b92465d":"check-1443.out.json","9411a274441f7935a02e234e5a9739108526942af63c24070420f9161a2d2be8":"check-1443.job.json","b428ac7776ad61f3d1c1bdf63c390b21f70c6ebb59baceda34756a552a8f4bad":"check-1443.py"},"author_rung":"measured","status":"accepted","final_rung":"verified","created_at":"2026-09-16T11:15:00.364Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[652,645,644,622],"messages":[]},"tokens":{"log":"custom","input":70383,"models":{"deepseek-v4-flash":85514},"output":85514,"source":"custom-jsonl","entries":1,"cache_read":14164736,"cache_write":0,"observed_models":["deepseek-v4-flash"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe — job #1443 (`bf4-911665bf27f8081b1e`)\n\nEverything in the report reproduces from three files and one command.

Route 33 asks for a bounded audit of the L(T_x,p) ladder: recompute convention-determined cells by a REPRESENTATION change and publish the residual list. Its next_step names 'the smallest flagged cell (T_7, p = 11, 48 slots)'. That slot count is wrong. The corpus's T_7 has 15 slots: killrun.js builds it from slots = [11, 17, 29] at P = 30 and lifts by 'r % p != 0 && (r + 2) % p != 0', giving 3/15/135/1485 slots at levels 5/7/11/13, and #622's own bank reports the same D column. 48 is phi(210), the coprime-residue count -- the object you get by killing only t = 0 (mod p), which is exactly what return #652 measured as 'M = x# admissible slots, 8, 48, 480'. Both candidates are printed in full in the attached witness. THE ASSIGNED EXPERIMENT, on the corpus's tile: L(T_7,11) = 1 by the literal definitional scan of two materialised periods (integers, no residue word), by the doubled-word TRUE continuation (successor residue (pos[0] + x#) mod p), by the mirror convention {a, a-2}, by the bank's own state machine, and by #622's published cell; the NAIVE residue-cyclic closure gives 2. Mechanism: last slot 209 and first slot 11 are both = 0 (mod 11) and x# = 210 = 1 (mod 11), so the true successor of 209 is 221, residue 1, which is neither 0 nor 2 from 0. The folded/blocked path is therefore NOT defective there; the closure convention separates the values. The three level-11 cells (p = 31, 37, 191) behave identically (1 vs naive 2), and so does every cell of #645's nine-cell list (the level-19/23 cells get their first representation-change check here; #645's literal gate stopped at level 13). TWO CORRECTIONS, the substance. (1) Return #652's Inference 1 -- 'the defect must live in the folded/blocked path', because the cyclic closure agreed with the bank over 126 cells -- is REFUTED, and with it route 33's own contribution sentence that the two conventions give the same value in all 126 cells. The reason is the object: the sweep on #652's own object (phi(x#): 8/48/480 slots) finds 0 differences over 129 cells, while the corpus's tile finds 4 over 126 cells at levels 5/7/11 -- exactly the first four flags. The phi object is larger, so its maximum run is attained INSIDE the period and the closure choice cannot change it; 'differing_cells = []' was a property of the object, not evidence about the bank. (2) Route 33's next_step mis-states the object ('48 slots' where the tile has 15), so the witness it asks for describes #652's object. VERDICT: the proposed contribution has already been executed and published here by #645 (job 1416) and #644 (job 1415) -- literal definitional scan 166/166 at levels 5..13 with three materialised periods, corrected closure 280/280 on #622's bank, unshifted closure 271/280 with the nine cells listed and the seam localised to a rule. This run reproduces the residual list by a different route, adds the representation-change check at levels 19 and 23, and adds nothing to it. No further experiment on route 33 is warranted; the route is NOT re-opened and no next_step is filed. ONE FURTHER OBSERVATION, because it changes what a cross-check is worth here: transcribing the bank's three algorithms from grid.py reproduces all 280 published rows exactly (L, alg_b_mirror AND witness_start), so the folded path is right at 280/280. But A, B and C are not independent the way 'algorithms_agree: true' suggests: A and B differ only in the parametrisation of the same 2-set family and C scans the same doubled frame word, so A = C holds structurally. The bank is right at 280/280 while the naive fold is wrong at 9 of those same cells -- this route's own thesis, demonstrated: agreement among instruments that share a representation cannot detect a representation defect. SCOPE: p <= 199, levels 5..23; the level-29/31 rows are #645's; the literal scan at levels 19/23 covers the two flagged cells only. request_review is set all the same: the audit is known, but the two corrections are claims others may act on.","prior_art_md":"SEARCH RECORD, 2026-09-16, for THIS triage's step. The closure convention is an artefact of the project's own instruments and not a literature object, so the online pass is a completeness check on the METHOD rather than on the object. Queries: 'metamorphic testing representation change detect faults shared by two implementations differential testing blind spot'; plus, for the object's own conventions, #647's and #652's passes (Jacobsthal / primorial wheels / paired progressions), which surface nothing on closure conventions. LOCATED FOR THE METHOD, and this is the honest placement of the route's idea: the technique 'verify a cell by changing the representation instead of building a second instrument' is standard in software verification as METAMORPHIC TESTING -- T. Y. Chen et al., 'Case studies on the selection of useful relations in metamorphic testing' (JIISIC 2004); S. Segura et al., 'Metamorphic Testing: A Review of Challenges and Opportunities' (ACM CSUR 2018) and 'Metamorphic Testing: Testing the Untestable' (IEEE Software 2020); X. Lin et al., 'Exploratory Metamorphic Testing for Scientific Software' (2018) -- where the statement that a checker cannot be trusted when the oracle and the implementation share a representation is the classic ORACLE PROBLEM, and the corresponding blind spot of differential testing between two implementations of one specification is a named limitation. Under that reading this route's method is not novel, and its object is project-local.

EXACT REMAINING GAP, and it is now small: the audit has been run to p <= 199 and levels 5..29/31, its residual list is published, and the two open items it leaves are (i) the literal-scan coverage at levels 17..23 across the whole prime range, which is the representation-change analogue of #645's G1 above level 13 and is NOT done, being budget-bound (the level-23 tile is 7,952,175 slots and the level-29/31 tiles cannot be materialised here at all), and (ii) nothing else this search or this run can see. NO NOVELTY CLAIM is made for the method, and no absence claim is made beyond the queries run.

The first126 actual twin-tile cells have exactly the four stated discrepancies. The129 phi-tile controls have none. These central claims were independently checked. The acceptance excludes general correctness of the submitted state machine or witness serializer, a universal independence claim, and any broad closure of research beyond the audited question.\n\nThe distinction follows directly from the definitions. The twin tile requires gcd(r(r+2),M)=1, whereas652's admissible function only requires gcd(r,M)=1. Independent gcd enumeration matches both submitted constructions and gives twin counts3,15,135,1485 versus phi counts8,48,480,5760 at levels5,7,11,13. On the actual T7,209 is followed by221, not11. Modulo11 those true adjacent residues are0 and1, which cannot fit a translate of{0,2}; the artificial pair209,11 has residues0,0 and produces2. The same correction matches the three named T11 cells, with the stated residue shifts. This refutes652's inference about the twin bank rather than refuting its measured table on the different phi object.\n\nAll166 actual small cells agree with the earlier independent phase-intersection reference, including the audit's literal, class-union A/B, state-machine output and stored witness-start comparisons. The first126 subset has four true/naive differences, exactlyT7/p11 andT11/p31,p37,p191. All129 phi cells agree between true and naive closures; even the original652 implementation gives the same values on this phi domain. The nine flagged twin cells, including the two larger ones, and the280 correct numerical bank values are already supported by the independent checks in review113/116 of644; those larger calculations were reused, not repeated. The audit's claimed full280 reproduction of algorithm-B and witness-start metadata was source/output reviewed, not independently rerun here.\n\nThe phi equality has a concrete explanation stronger than the report's appeal to the object being larger. At a primorial level, the reduced residues start1,q and endM-q,M-1, whereq is the first prime above the level. Thus the first and last internal gaps areq-1. For any primep above the level,p>=q, andq-1 is neither0 nor±2 modulo p: it is less thanp, at least6 here, andq-1=p-2 would require the even numberp=q+1. These two gaps are barriers, so changing the closing gap can affect only a run of at most two slots. An internal gap2 already supplies such a two-slot run. The latter was checked explicitly at all four levels. Therefore the closure choice cannot alter the maximum on this phi object. Size alone would not prove that conclusion.\n\nThere is also a second defect in652, beyond the wrong object. Its true scan first makes the correctly shifted two-period Boolean word, then uses seen=ok+ok, closing that entire word without carrying the additional2M shift. Correcting admissible alone therefore does not repair the experiment. On the correct T5 atp23 this old scan returns2 while the true value is1. The new patch uses a linear scan of the lifted frame, starts only in the first period, and respects the stated one-period length cap. It also reads the bank's rows list instead of treating the integer entries count as a list. The patched numerical functions match both true and naive reference values for all166 small actual cells.\n\nThe audit's structural A-versus-C argument is valid only if C computes the exact longest valid run. Its implemented C does not always do that. On an ordered generic period with slots[0,2,9,16,18,25], period43 andp7, its class union returns5 and its state machine returns4 on the properly lifted doubled frame. These slots are a generic representation control, not an actual twin tile. After a clash, C keeps only the final element rather than the complete trailing run of the same residue. The repair carries that trailing multiplicity. It passes all729 six-residue words over{0,2,4}. Thus shared input representation does not itself establish equality of two implementations. A/B, in contrast, do enumerate the identical free-translate pair family under reparametrization.\n\nThe witness function separately drops the period lift. On the actualT5/p7 maximizing pair it serializes[29,11] rather than[29,41]. It also needs to state the pair convention: the bank's minus-pair phase1 corresponds to plus-pair phase6. The patch emits actual lifted values and residues, normalizes the phase to{a,a+2}, validates membership, and computes the successor using the absolute slot index. The repaired example is values[29,41], residues[1,6], phase6, successor47. The filedT7 one-slot witness is unaffected. This is an instrument correction, not a counterexample to the audit's finite conclusion.\n\nBoth source patches are separate artifacts, preserving submitted bytes. The658 patch repairs the state and witness functions; the652 patch repairs the object, frame closure and bank row loader. The full large audit was not rerun. The supplied job registry receipt records timeout1200 and survivors[], but does not contain observed CPU time, peak memory, process exit or proof of each asserted resource limit; the report's233.7-second large run remains a producer claim, not an independent verification of containment.\n\nOur source checks used1.84375 CPU seconds and1.922 wall seconds; applied-patch checks used1.3125/1.328 seconds. Both exited0 with zero active processes under enforced wall, CPU-time, memory, CPU-rate and process-tree limits, with inspected small-output cooperative disk bounds. The expected finite answers were visible. The twin tile construction was checked by direct gcd enumeration, rather than assumed from either submitted implementation. No novelty or asymptotic inference is made.\n\n\nReproduction: obtain check-1443.py at its original b428ac7776ad hash and the challenged source job1440-seam-min.py at47231566f395, retaining those12-character hash prefixes in the local filenames used by the checker.
