Scrubbed transcript: bearer token, session ids, e-mail, home paths, account identifiers redacted as data; the sub-agent's prior-art log is appended.\n\n**Caveat and open gap first.** Everything here is a finite computation on the served bank's own domain (levels 5..23, all 280 bank cells); nothing is proved about L in general and nothing here prices G2. The bank copy I compared against is the one served at content address `b7451a99…f3c9` (69,685 bytes); the address `813c6581…4dfb` that return #644 reported returns \"no such file\" today, so that custody question is recorded, not resolved.\n\n## 1. Classification of the obstruction\n\nRoute 34 is `blocked` because its dependency #653 was rejected. Sorting what actually happened:\n\n| item | class | evidence |\n|---|---|---|\n| \"slots 11 and 13 are adjacent in T_5 with residues 0, 2 mod 11, so L(T_5, 11) ≥ 2\" (#653, the route's founding premise) | **refuted statement** | 13 + 2 = 15 is not coprime to 30; T_5 = {11, 17, 29}. Review 132 (@admiralorbiter, trusted) and return #663 both say so; my slot builder from the definition gives |T_5, T_7, T_11| = 3, 15, 135 (= OEIS A059861) against #653's 8, 48, 480 (= φ(x#)). |\n| the route's dichotomy \"producer returns 2 ⇒ serialisation bug; returns 1 ⇒ definition and ladder disagree by construction\" | **failed attempt (ill-posed)** | the two objects compared were different sets; #663 ran the producer (L = 1 at T_5, p = 11) and my fresh implementation of the documented definition gives 1 too. Neither branch holds. |\n| \"reproduction of the ladder means reproduction of the producer\" | **refuted** for the served bank | a fresh implementation of the documented definition, no producer code, reproduces the bank at 280/280 cells (Section 2). The bank is a realisation of the statistic, not of a script. |\n| the closure-convention question at the seam | **known** (return #645, accepted, measured) and **now independently reproduced** | see Section 2: unshifted residue-cyclic closure differs from the literal integer scan at exactly #645's listed cells, and the bank follows the literal scan. |\n| custody of the bank bytes (#644's hash vs #622's) | **unresolved, minor** | the `b7451a99` copy serves and matches the definition at every cell; the `813c6581` address is gone. Nothing in the values is affected. |\n| route 34's contribution (\"pin the statistic before any ladder audit\") | **result** | pinned: L is the documented run statistic on the twin-coprime set T_x = A059861's set, with the period seam closed by carrying M mod p (literal integers), and the served bank is that statistic at every cell checked. |\n\n## 2. What was computed (`Lconv1895.py`, fresh code, no author code)\n\nTwo slot sets: T_x = {r mod x# : gcd(r, x#) = gcd(r+2, x#) = 1} (the corpus tile; killrun.js line 49–52 and verify-ladder-big.js line 3/11 build exactly this, read today) and U_x = {r : gcd(r, x#) = 1} (what #653's script used). Two closures for \"longest run of consecutive slots whose residues mod p lie in {a, a+2}, max over a\": LIT scans the slots of two consecutive periods as integers r and r + M, so the residue across the seam is shifted by M mod p; CYC treats the length-n residue sequence as periodic with no shift. Compared to the served bank row by row.\n\n| comparison | domain | agree | differ at |\n|---|---|---|---|\n| bank vs T_LIT | #653's 126 cells (levels 5, 7, 11; x < p ≤ 199) | **126/126** | — |\n| bank vs T_CYC | same | 122/126 | (7,11), (11,31), (11,37), (11,191) |\n| bank vs U_LIT, bank vs U_CYC | same | **4/126**, 4/126 | everything else (reproduces #653's \"4 of 126\") |\n| U_LIT vs U_CYC | same | 126/126 | — |\n| bank vs T_LIT | all 280 bank cells, levels 5..23, p ≤ 200 | **280/280** | — |\n| bank vs T_CYC | same | 271/280 | the four above plus (13,41), (13,43), (13,61), (19,199), (23,173) — exactly #645's nine cells |\n\nNamed cells: L(T_5, 7) = 2 (gate), L(T_5, 11) = 1, L(T_5, 13) = 1, L(T_7, 11) = 1 under LIT = bank; under CYC L(T_7, 11) = 2. On U_5 every named cell reads 2. The hand-checkable seam: T_7 mod 210 ends …197, 209 and restarts 11; residues mod 11 of 209 and of 11 are both 0, so the naive wrap makes a run of 2, but the next period's slot is 221 ≡ 1 (mod 11) because 210 ≡ 1 (mod 11): the literal scan finds no run of 2. That is #645's rule (\"M mod p ≠ 0 breaks the pair\") at its smallest instance.\n\nThree consequences, in order of weight.\n\n**(a) The route's question is answered at verified grade for the checked cells.** The served L column is the documented statistic on the documented set with the seam carried: 280/280 by an implementation that shares nothing with the producer but the definition. Together with #645 (280/280 under its corrected closure, accepted) and #663 (producer = bank, recorded), three independent instruments agree. Nothing is upstream of route 33 on this ground; route 33 must audit on the T_x lattice with the seam carried, and it now has a cheap gate: the nine cells of #645.\n\n**(b) #653's closure-agreement claim was true on the wrong set.** \"Literal scan and unshifted cyclic closure agree in all 126 cells\" holds on U_x (126/126 here) and fails on T_x at four of those cells. So #663's sentence that this agreement \"is untouched and stands\" is correct only for the reduced-residue set #653 actually computed on; on the corpus's set the two closures are not interchangeable.\n\n**(c) One sentence of #663 is wrong and should not be inherited.** #663 says #645's nine-cell list \"is a subset of the same separation, not a closure-convention list\". It is both: at those cells the twin set under the unshifted closure gives 2 and under the literal scan gives 1 (this return, all nine cells, level 23 included), which is precisely what #645 measured and was accepted for. #663's producer runs were all seam-correct, so it never saw the closure difference; its inference about the list is the error, not its numbers.\n\n## 3. Prior art\n\nIn `prior_art_md`. The decisive external fact: OEIS A059861's FORMULA line is the corpus's T_x verbatim, with the count ∏_{i≥2}(p_i − 2) = 3, 15, 135, 1485, 22275, 378675; A049296 exhibits φ(210) = 48 reduced residues against 15 twin gaps for x = 7. No source defines L(T_x, p) or names the seam convention; that is internal to the corpus and is decided above.\n\n## 4. What I did not do\n\nNo producer or checker of #622/#663 was run or read beyond the two slot-set lines of killrun.js and verify-ladder-big.js. The level-23 pass (7,952,175 slots, 40 primes) took 1,193 CPU s single-threaded; everything else is under a minute.

Route 34 was blocked because #653 was rejected. Sorting: #653's founding premise (slots 11 and 13 adjacent in T_5 with residues 0, 2 mod 11) is a REFUTED STATEMENT - 13+2 = 15 is not coprime to 30, T_5 = {11,17,29}, |T_5,T_7,T_11| = 3, 15, 135 (= OEIS A059861) against #653's 8, 48, 480 (= phi(x#)); review 132 and #663 already say so and my slot builder from the definition confirms it. The route's dichotomy (producer returns 2 => serialisation bug; returns 1 => definition and ladder disagree by construction) is a FAILED ATTEMPT: both branches compared different objects and neither holds. The route's contribution - pin which statistic the ladder realises before any audit - is a RESULT: the served L column is the documented run statistic on the twin-coprime set with the period seam closed by carrying M mod p, reproduced by a fresh implementation that shares nothing with the producer but the definition.\n\nMEASURED (Lconv1895.py, no author code). Two slot sets, T_x (corpus tile) and U_x (reduced residues, what #653 computed on); two closures, LIT (scan two consecutive periods as integers, so the residue across the seam is shifted by M mod p) and CYC (residue sequence treated as periodic, no shift). Against the served bank b7451a99...f3c9 (280 rows): bank = T_LIT at 126/126 of #653's cells and at 280/280 of ALL bank cells (levels 5..23, p <= 200); bank vs T_CYC 271/280, differing at exactly (7,11), (11,31), (11,37), (11,191), (13,41), (13,43), (13,61), (19,199), (23,173) - precisely the nine cells return #645 (accepted) listed as seam-sensitive; bank vs U_LIT and U_CYC 4/126 (reproducing #653's \"4 of 126\"); U_LIT = U_CYC at 126/126. Named cells under LIT = bank: L(T_5,7) = 2 (gate), L(T_5,11) = 1, L(T_5,13) = 1, L(T_7,11) = 1; under CYC L(T_7,11) = 2; on U_5 every named cell reads 2. Hand check of the smallest seam: T_7 ends ...197, 209 and restarts 11; 209 and 11 are both 0 mod 11 (naive wrap gives a run of 2) but the next period's slot is 221 = 1 mod 11 because 210 = 1 mod 11, so the literal scan finds no run of 2. That is #645's rule at its smallest instance.\n\nTHREE CONSEQUENCES. (a) The route's question is answered at verified grade for the checked cells: three independent instruments now agree (#645's corrected closure 280/280, #663's producer runs, this fresh implementation 280/280). Nothing is upstream of route 33; route 33 must audit on the T_x lattice with the seam carried, and #645's nine cells are its cheap gate. (b) #653's \"literal = unshifted cyclic closure in all 126 cells\" is true on U_x (126/126 here) and false on T_x (4 of those cells), so #663's \"that agreement is untouched and stands\" holds only for the set #653 actually used; on the corpus's set the two closures are not interchangeable. (c) One sentence of #663 is wrong: #645's nine-cell list is NOT merely \"a subset of the twin/reduced separation, not a closure-convention list\" - at those cells the twin set under the unshifted closure reads 2 and under the literal scan reads 1, exactly as #645 measured and was accepted for. #663's producer runs were seam-correct so it never saw the difference; its inference about the list is the error, not its numbers. Do not inherit that sentence.\n\nPRESERVED. Review 132's refutation; #645's nine cells and rule; #663's producer measurements; #644's 280 values. UNRESOLVED, MINOR: #644 reported the bank served at 813c6581...4dfb (80,567 B); that address returns \"no such file\" today and the b7451a99 copy (69,685 B) is what serves; the values match the definition at every cell, so nothing numerical depends on it. FALSIFIER: any bank cell on levels 5..23 where the literal-scan value on T_x differs from the row (none on all 280), or a T_x count differing from A059861 (none: six levels match). No next experiment: the statistic is pinned and the route's purpose is served; further work belongs to route 33 on the pinned lattice.","prior_art_md":"Search date 2026-09-18, pass for the CHANGED ingredient after #653's rejection: the identity of the slot set (reduced residues vs twin-coprime pairs mod x#), any external tabulation of that set, any per-prime run statistic on the twin sublattice, and whether the period-closure convention is named anywhere.

(b) No source defines or tabulates the per-prime statistic L(T_x, p) (longest run of consecutive twin-admissible slots mod x# with residues mod p in {a, a+2}); the nearest object is Ziller-Morack's h_2, joint over all primes. (c) No source names the period-closure / wrap-around convention for run statistics over a periodic residue set; OEIS pages close one period implicitly. So the closure question measured in this return (literal integer scan across the seam vs unshifted residue-cyclic wrap) has no external owner and is decided only by the corpus's own producer and served code.\n\nEXACT REMAINING GAP. None on the slot set: it is A059861. On the statistic: whether the served bank's L is the literal-integer-scan value or the residue-cyclic value is an internal convention question, answered in this return's evidence by comparing both against the bank cell by cell; nothing external bears on it. Queries are in the transcript (sub-agent prior-art search)."},"research_route_id":34,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":"2026-09-18T14:21:48.924Z","department_id":null,"run_id":null,"triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"natepac","job_brief":"Inspect the decisive obstruction with a fresh perspective.

Its dependencies are #644 (accepted, verified) and #645 (accepted, measured).

Two implementations that share nothing but the definition now agree at every cell of a finite, exhaustive comparison, so verified is the defensible rung for the computational core.\n\n**What I checked.**\n1. **Files.** All seven files match their sha256. The served bank b7451a99… also matches (69,685 B, 280 rows).\n2. **Code vs claim.** Lconv1895.py implements exactly what §2 states. `slots(x, twin)` builds T_x = {r : gcd(r, x#) = gcd(r+2, x#) = 1} or U_x. `L_lit` scans the residues of r and r + M over two periods, so the seam shift M mod p is carried, and caps the run at n. `L_cyc` rolls the length-n residue ring to start at a non-member and takes the longest run, which is the unshifted wrap. The max over a is taken over {a, a+2}.\n3. **Output vs code.** Using a read-only script over Lconv1895.json I recomputed every tally. The `bank` field equals the served bank at 280/280 cells. bank = T_lit at 280/280. bank ≠ T_cyc at exactly (7,11), (11,31), (11,37), (11,191), (13,41), (13,43), (13,61), (19,199), (23,173). These are #645's nine cells, as listed in #645's report. On levels ≤ 11, bank = U_lit at 4/126 and U_lit = U_cyc at 126/126. |T_x| = 3, 15, 135, 1485, 22275, 378675, 7952175 matches A059861. Lconv1895-19.json agrees on its 243 cells.\n4. **Independent execution already exists, and I reused it rather than rerunning.** Triage 61 (job 2398, a run of this reviewer's account) ran a JS re-implementation written from the definition. It builds T_x by lifting level by level and tracks runs per class, and it shares no code with the author's numpy approach. That run reproduced LIT 280/280 and CYC 271/280, with differences at the same nine cells and the same |T_x| through level 23 (28 CPU s, exit 0). I read its code: the membership test a ∈ {s, s−2}, the 2n scan and the cap at n are correct. The U_x half is independently corroborated by #653's own measurement (naive = literal at 126/126, bank matches U at 4/126).\n5. **Hand check of the smallest seam.** T_7 ends …197, 209 and restarts at 11. 209 = 11·19 ≡ 0 and 11 ≡ 0 (mod 11), so the naive wrap gives a run of 2. But 210 ≡ 1 (mod 11), so the next period's slot is 221 ≡ 1 and the literal scan gives 1. The bank has 1.\n6. **Consequence (c), #663's sentence.** #663 says the nine-cell list is \"a subset of the same separation, not a closure-convention list\". On T_x it is a closure-convention list at all nine cells (T_lit 1, T_cyc 2). The \"subset\" half holds literally only for the four cells inside #653's 126-cell domain, (7,11), (11,31), (11,37) and (11,191), which are among the 122 bank ≠ U cells. The other five lie outside that domain. So the return's \"it is both\" is right, and the part to drop is \"not a closure-convention list\".\n7. **Consequence (b).** #653's literal = unshifted-cyclic agreement holds on U_x and fails on T_x at four of its 126 cells. #663's \"untouched and stands\" therefore holds only for the set #653 used.\n8. **Flagged line 44 (time cap).** It cannot have fired: the check runs only before each level, and level 23 began at about 46 s, far below the 900 s cap. The captured stdout is therefore unaffected. The replacement 602df19f… only moves that print to stderr. The .out files also contain stderr progress lines and a date, which are not part of the stdout artifact. No further fix is needed.\n\n**Minor gaps (they do not change the rung).** The script opens `bank-b7451a99.json` from cwd, but the recipe never says to fetch /files/b7451a99… under that name. The 813c6581… custody question is recorded but unresolved, and it affects no value.\n\n**Falsifier.** Any bank cell on levels 5..23 where the literal-scan value on T_x differs from the row (none of the 280 does, under two implementations), or a |T_x| that differs from A059861.\n\n**Attribution.** Complete.
