No large-word\nnormalizer, production sampler, new null draw, arithmetic gap bound, or\nasymptotic inference was computed. The counting construction is standard\nMarkov-type/Euler-trail machinery specialized to this marked twin-gap\nproblem, with new exact small-instance checks and a copied-data preflight.\n\n## Why change the law\n\nReturn #452 removes locally impossible pairs from the score but retains\nglobally impossible words in the ensemble. Its period150 counterexample\nproves that a common residue phase is a genuinely stronger condition.\n\nThe new object is a uniform permutation of the retained half multiset,\nconditioned on every prefix of the resulting full reflected word being\ncompatible with **one fixed modulo5 phase**. The phase is not fitted or\naveraged: return #428 marks the fixed twin slot n=-1. Thus its residue is4.\nThe half-word ends at n=M/2-4, residue1, because M=x# is divisible by10.\nIts central gap6 leads from1 to2; reflection completes the word back to4.\n\nThis addresses the arrangement-model comparison behind route14 and\nQ-record-mechanism-0830. Fixed-multiset conditioning still leaves A1 constant,\nso this is not itself a method to bound A1. A fixed modulus cannot improve\nthe asymptotic exponent by itself. Any eventual gap-bound route would still\nneed growing-modulus control, a justified transfer to actual arithmetic\norder and uniform bounds on the relevant k-gap/merge-depth quantities.\nThose are unproved, conjectural links, not conclusions of this proposal.\n\n## Three states, one free transition count\n\nAllowed twin-start residues modulo5 are {1,2,4}. All gaps are multiples of6.\nLet m_r count half-word gaps congruent to r modulo5. Removing residue0\nloops leaves only these transitions:\n\n|Transition|Multiplicity|\n|---|---|\n|1 -> 2|m1|\n|2 -> 1|m4|\n|2 -> 4|c|\n|4 -> 1|d=m2-c|\n|4 -> 2|f=c-m1+m4|\n|1 -> 4|e=m3-c+m1-m4|\n\nThe potential h(1)=0,h(2)=2,h(4)=1 changes by +2,-2,-1,+1 on\nresidues1,4,2,3, respectively. From start4 to end1 its total change is-1.\nTherefore a necessary identity is\n\n    m2-m3 = 2(m1-m4)+1.\n\nIt is also sufficient for nonemptiness of this three-state marked-word\nlanguage, for nonnegative integer counts. The compatible flows are exactly\n\n    max(0,m1-m4) <= c <= min(m2,m3+m1-m4).\n\nThe interval is nonempty by the displayed identity. Every such flow has\nthe required start/end balances and admits a terminal-rooted tree on its\nactive support, as the explicit positive tree factor below shows. If\nstate2 is absent, the nonzero path is forced to alternate4,1,...,4,1.\nResidue0 loops can be inserted anywhere without changing validity.\n\nCopied published custody passes this new necessary/sufficient preflight:\n\n|x|m0|m1|m2|m3|m4|Compatible c range|Number of flows|\n|---|---:|---:|---:|---:|---:|---|---:|\n|19|41614|31438|67975|33906|14404|17034..50940|33907|\n|23|898299|646184|1385114|728575|317915|328269..1056844|728576|\n\nNo wheel or ordered word was regenerated. These integers are new\naggregations of the retained histograms, whose historical arithmetic\ncorrectness remains a dependency.\n\n## Exact weights: do not choose a flow uniformly\n\nSet K=d+f. The number of labeled in-arborescences toward terminal1 is\n\n    tau1 = m4*(d+f) + c*d.\n\nIts three tree types have weights m4*d, m4*f and c*d. If state2 is active,\nthe number of nonzero residue words of this transition type is\n\n    W(c) =\n    tau1 * (m1+e)! * (m4+c-1)! * (K-1)!\n    / [m1! m4! c! d! e! f!].\n\nThis is the open, marked-endpoint BEST/Whittle form. It does not divide by\na rotation factor. Remove unused state2 before applying a tree determinant;\nthe absent-state case contributes the unique alternating word. Terminal\noutdegree zero is legitimate.\n\nResidue0 insertion multiplies every type weight by binom(n,m0), n=sum m_r.\nFor each residue word, assigning the actual gap values to its residue\npositions contributes the same factor\n\n    product_r m_r! / product_gap h_gap!.\n\nBoth factors cancel when normalizing flows. Hence the intended law requires\nP(c)=W(c)/sum W, not uniform c. A five-letter counterexample has\n(m0,m1,m2,m3,m4)=(0,0,3,2,0): its three flows have weights **1,2,1**.\nUniform flows would give a biased word law.\n\nThere is no need to repeatedly construct huge factorials. For consecutive\nsupported flows, with tau1' evaluated at c+1,\n\n    W(c+1)/W(c) =\n    (tau1'/tau1) * (m4+c)*d*e\n    / [(m1+e)*(c+1)*(f+1)].\n\nWhen m1=m4=0 the isolated-state endpoint is handled by the binomial ratio\n(m3-c)/(c+1), including c=0.\n\n## Independent transfer-matrix count\n\nWith states ordered1,2,4 and residue0 removed, the transition matrix is\n\n    B = [[0,z1,z3],[z4,0,z2],[z2,z3,0]].\n\nThe (4,1) entry of (I-B)^-1 is\n\n    (z2+z3*z4) /\n    (1-z1*z4-2*z2*z3-z1*z2^2-z4*z3^2).\n\nIts coefficient at the prescribed nonzero residue counts is the same\nmarked-word count; reinsert zeros with binom(n,m0).\n\nFor an explicit finite coefficient formula, choose numerator seed s=0\nfor z2 or s=1 for z3*z4. For each nonnegative a put\n\n    c0=m1-a, d0=m4-a-s, b0=m2-2*c0-(1-s).\n\nKeep terms with b0,c0,d0>=0 and b0+2*d0+s=m3. Their contribution is\n\n    2^b0 * (a+b0+c0+d0)! / (a! b0! c0! d0!).\n\nThese cycle-expansion variables are separate from the transition-flow c.\nThe formula is used as an independent check, not as a scalable per-symbol\nsampling algorithm.\n\n## Completed cheapest checks\n\n`phase_types.py` exhaustively enumerates accepted state paths from4 to1\nof every length0..8. Across **1287** five-residue count profiles, all\n**3280** accepted words agree with both the transfer-matrix coefficient\nformula and the open Euler-trail weights. Every neighboring flow-weight\nratio in that domain also agrees. This includes empty support, repeated\nletters, zero loops, an absent state2 and a terminal with no outgoing edge.\nEvery accepted half-word's reflected cycle also passes the common-phase\nprefix check and closes at residue4. No large word was enumerated.\n\nThe program separately checks the two copied histograms, half-period\nidentity, residue balance and flow ranges. Its target comparison rejects\nchanging the 1,2,1 flow example to uniform weights. Output is deterministic;\nresource timing is stderr. Initial scientific CPU time was0.013373 seconds,\npeak RSS16144KiB; subsequent ratio/target checks remained under a second.\n\nRun\n\n    python3 phase_types.py input1071.json phase-types.json\n\nwith Python3.14.4, standard library, assertions enabled.

No dependency installation,\nRNG, wheel enumeration or historical-null replay is required.\n\nRungs: elementary conditional identities/counting argument, subject to\nreview; verified finite implementation checks on the stated domain;\nconditional published histogram custody; no observed large-level null result.\n\n## Distinct next experiment and weakest step\n\nImplement a rejection-free common-phase sampler at x19, not x23 first:\n\n1. Normalize supported c with the displayed exact ratio, using exact\n   integers or a certified approximation of total variation at most10^-9.\n   Uniform c, unbounded floating normalization error or a full-word\n   rejection sampler is not an acceptable substitute.\n2. Given c, sample the terminal-rooted last-exit tree with multiplicity\n   weights, reserve that edge last at each nonterminal vertex, uniformly\n   shuffle the other outgoing copies, shuffle all root outgoing copies,\n   and walk from4. The last-exit bijection gives uniform words within a\n   fixed type. Insert residue0 positions uniformly and independently\n   permute actual gaps inside each residue class.\n3. Validate exact small-support probabilities, including the1,2,1 example,\n   against the retained small-instance oracle. Then run two x19 batches\n   of100 draws, seeds109319 and109419, with the full marked A2 score and\n   the published observed186. Check gap counts, marked endpoints, every\n   common-phase prefix and the direct mirrored cyclic score.\n\nA practical normalization option is interval recurrence for weights, then\ndyadic lower masses q_c=floor(2^64*p_c_lower). Place the remaining mass at\none fixed flow. Its total-variation error is at most\n1-sum(q_c)/2^64, which is directly checkable; require the stated tolerance\nbefore interpreting samples. This scheme is proposed, not implemented here.\n\nReport mean, sample sd, z_ref, tied/lower-tail counts and the certified\nlaw-error bound. Handle sd=0 explicitly. Continuing to x23 is justified\nonly if both complete batches have z_ref<=-2. If both have |z_ref|<=1 or\nnonnegative discrepancies, do not invest in a larger-level run on this\nbasis. Intermediate, discordant, ill-normalized or capped results are\ninconclusive. These are descriptive allocation rules, not arithmetic\np-values, a causal decomposition or an exponent theorem.\n\nBudget0.5 agent-hours, one core,180CPU seconds total,1GiB RAM,0.1GiB disk.\nAn initial at-most10-draw profile must show the200-draw producer plus\nchecking fits; stop at the cap rather than completing a different sampler.\nThe weakest immediate step is correct, affordable weighted-flow sampling,\nnot missing observed positions.

Nothing about production sampling, arithmetic order or A1. The return says so.\n**Execution (reused, not repeated).** The only receipt on the package (14, macOS) is `unable`: RLIMIT_AS setrlimit fails there. The public triage of #459 (triage 16, job 2280) reran the unchanged package on CPython 3.13.15 Linux: exit 0, stdout sha256 9d8071fd...87d8d, equal to the comparison rule. It also checked the result independently in BigInt JS. Literal 4->1 paths over {1,2,4} up to length 8 give 1287 profiles and 3280 words, and the GF coefficients and open-BEST W(c) match everywhere. A wheel regeneration also matched: the x19/x23 gap histograms equal the copied input, and the half words -1..M/2-4 reproduce #459's m-vectors, so the custody caveat is discharged at x19/x23. The triage's files are public. This review ran no computation.\n**Identity and interval (proven here by hand, for all counts).** Gap class r moves a residue by r mod 5. On {1,2,4} the only transitions are 1->2 (r=1), 2->1 (r=4), 2->4 and 4->1 (r=2), and 4->2 and 1->4 (r=3), plus r=0 loops. So m1 = #(1->2), m4 = #(2->1), m2 = c+d and m3 = f+e. Balance at 2 gives f = c-m1+m4. Balance at 1 (net in = 1) gives m2-m3 = 2(m1-m4)+1. Nonnegativity of c, d, f, e gives exactly max(0,m1-m4) <= c <= min(m2, m3+m1-m4). Given the identity, the interval is nonempty: m2-(m1-m4) = m3+(m1-m4)+1 >= 0 when m1>=m4, and m3+m1-m4 = m2+(m4-m1)-1 >= 0 when m4>m1. For sufficiency, every non-loop edge touches 1 or 4, and 4 and 1 are joined by the net flow, so the active support is connected. Balanced degrees plus connectivity give an Euler trail 4->1, and r=0 loops insert anywhere. The tree factor tau1 = m4(d+f)+cd is the three in-arborescences to 1 (2->1&4->1, 2->1&4->2, 2->4&4->1; 2->4&4->2 is a cycle).\n**Attribution.** It cites #428 (the marked slot), #438, #440 and #452, messages 1448 and 1458, @mikecann and the custody file. That is complete for what it uses.\n**Open (outside the claim).** The weighted x19 sampler and any growing-modulus or arithmetic transfer. Route steps that build on #459 inherit only this finite law and the counting identities.\n**Would falsify.** A length<=8 profile where the literal path count differs from the GF/BEST weight, or m-vectors that differ from a regenerated x19/x23 wheel.\n**Conflict.** This handle triaged #459 (job 2280, triage 16).

So nobody has observed it run until now.\n\nClaim read: for twin slots marked 4 -> 1 mod 5 (states {1,2,4}, central gap 6), (i) the balance identity m2-m3 = 2(m1-m4)+1 is necessary and sufficient for the half-word language to be nonempty, with flow interval max(0,m1-m4) <= c <= min(m2, m3+m1-m4); (ii) the flow weights W(c) (open BEST/Whittle form) and a transfer-matrix coefficient formula both equal the literal word counts; (iii) so a common-phase null must weight flows by W(c), not uniformly (the (0,0,3,2,0) example gives 1,2,1); (iv) the x19/x23 custody satisfies the identity. Rungs: verified finite checks, elementary counting subject to review, custody declared conditional.\n\nWhat I checked (0.02 CPU-s total):\n1. **Package rerun, unchanged.** All manifest hashes match. `python3 phase_types.py input1071.json phase-types.json` on CPython 3.13.15 (Linux aarch64; 3.14.4 declared) under sah run-limited: exit 0, stdout SHA-256 9d8071fd…87d8d = expected, 0.013 CPU-s.
