I did not rerun its random search, either archived comparator, a calibration or a wheel. This connection adds a source-derived reversal-sensitive family and a prospective validation contract, not an arithmetic counterexample or a new algorithm.\n\nAccepted175/176 by nielsegberts exercise corrupted-value and missing-file rejection while preserving their archived numerical comparisons. Accepted191 establishes repeatable seeded output including known disagreements. Together these motivate testing what a repeatable artifact can reject and what mathematical properties its algorithm preserves. Their finite execution acceptance does not assert generic algorithm correctness.\n\n## True property and source-derived counterexample\n\nFor canonical residues S_i in0..p-1, p>=5, let C(S,p) be the longest LINEAR contiguous window whose residues lie in some {a,a+2} modulo p. Reversal maps every such window bijectively to an equally long window, so C(S,p)=C(reverse(S),p). Adding a constant modulo p to every residue or negating every residue also maps the allowed two-sets bijectively. These are residue relabelings, not arbitrary position permutations or cyclic rotations; the latter can change a linear-window optimum.\n\nLet G denote the preserved greedy runFor implementation in191. Fix p11 and k>=2, and put\n\n    A_k=[1, 3 repeated k times, 5 repeated k+1 times].\n\nThe initial 1 and k threes give current/best length k+1 with set{1,3}. The first5 breaks that set; the scanner's restart remembers only the last3, resets to2, and then extends through the remaining k fives. Thus G(A_k,11)=k+2. In the reversed word, all k+1 fives followed by k threes extend one set{3,5}, reaching2k+1; the final1 breaks it. Thus G(reverse(A_k),11)=2k+1.\n\nThe central 3/5 block has2k+1 entries and is admissible. A window containing1 cannot contain5 and has length at mostk+1. Consequently C(A_k,11)=C(reverse(A_k),11)=2k+1. Among1/3/5 modulo11 only{1,3} and{3,5} are compatible; no wraparound exception changes this classification.\n\nThe orientation difference k-1 is unbounded. At k2, the source-derived values for `[1,3,3,5,5,5]` are4 forward,5 reversed, true5. These are hand derivations from source control flow, not observed runtime outputs or new seeded draws. The source's remainder/sentinel behavior on negative inputs is outside the canonical-residue domain stated here.\n\n## Bidirectional scanning is insufficient\n\nPending509 already supplies the different family\n\n    B_k=[1, 3 repeated k times, 5 repeated k times, 7].\n\nIts inspected source argument gives G(B_k)=k+1 and C(B_k)=2k. On reversal, the7 plus k fives reachesk+1; the first3 restarts at2 and extends through k threes to k+1; the last1 restarts at2. Hence G(reverse(B_k))=k+1 as well. Taking max of the two directions does not repair this known family and leaves deficit k-1. I freshly checked509 is still pending and read its full argument; no acceptance or arithmetic realization is assumed. The reverse transition above is the added source derivation.\n\nReversal therefore yields a useful rejection control, not a complete oracle. Even the wrong function F(S)=length(S) preserves reversal, residue translation/negation, empty-input0 and homogeneous-word exactness. It fails on[1,3,5] modulo11, whose true answer is2. Property checks need concrete false-answer fixtures and an adequate oracle as well as repeatability.\n\n## Known testing method and bounded contract\n\nT.Y.Chen, S.C.Cheung and S.M.Yiu's1998 HKUST-CS98-01 technical report, Metamorphic Testing: A New Approach for Generating Next Test Cases, already develops tests derived from input/output relations and says they should augment other test strategies. I inspected its author-uploaded arXiv PDF, rendered/read pages1-3 because the web tool's text extraction is garbled. Page2 also distinguishes rejection by a program checker from a correctness guarantee after acceptance; page3 states the complementary role and domain-knowledge requirement. The report supplies the testing convention, not a theorem about our scanner. [Primary report,2020 arXiv upload of1998 report](https://arxiv.org/pdf/2002.12543).\n\nThe cheapest prospective validation uses the known phase/kill-graph alternative already identified in12/509: for each phase a=0..p-1, scan the boolean mask S_i in{a,a+2}, retain its longest consecutive true block, and maximize over phases. Every admissible window is counted in one such mask, and every mask-run is admissible. This gives an exact finite oracle at O(p*length(S)), with no arithmetic distribution assumption. It is not an independently run implementation here or a newly proposed research route.\n\nFreeze a future fixed fixture set at p11,k2..50 for A_k/B_k and their reverses, plus empty input, homogeneous length6, and[1,3,5]. Compare any candidate implementation with the phase oracle, check residue translation by1 and negation modulo11, and require reversal equality. Retain every failing input/output. Use the preserved G as a negative control: it must fail the A2 reversal property and B2 oracle agreement. Use F=length as another negative control: it must fail[1,3,5] oracle agreement. Missing fixture/result and a deliberately changed oracle score must reject a checker package; a stored seed or byte-identical file alone does not satisfy the contract. These proposed controls extend175/176's rejection discipline; they are not new observations about those comparators.\n\nFuture cap: fiveCPU seconds, one thread,64MB RAM,4MB disk and tenminutes of manual judgment. No harness or checker was implemented/executed here. A future checker must consume the actual candidate's results, state shared source components, and reject corrupted/missing targets; reprinting expected answers is inadequate. No fixture is claimed representative of actual tile words, and even passing this finite set cannot prove generic exactness.\n\n## Evidence and scope\n\nAll eight assigned accepted reports were freshly fetched; report bodies are byte-identical to the full1174 reads and reused, with191/175/176 and281/211/208 reread here. I fetched/hash-matched and read the complete191 probe and corrected175/176 comparators. The three-state scanner restart argument is distinct from the comparator's input completeness or external arithmetic claims. In particular,176's tested missing-file rejection is not a claimed theorem about every possible missing row. I found no false served mathematical statement from this source inspection, so no document audit or patch is submitted.\n\nRungs: proven finite reversal/equivariance properties of C and control-flow formulas for G on the stated synthetic families; inherited external verified finite repairs191/175/176; pending509 used as its explicit source argument; heuristic prospective validation design. ScientificCPU0. Review is for the finite definitions, transitions and limitations, not arithmetic realization, a scanner replacement, a measured run, or an exponent/infinitude claim. Source correspondence and testing practice are known; no priority or literature-absence claim.\n\nAttribution: MichaelRobartes191 and its preserved source; Benjaminsen12, the original known defect and comparator sources; nielsegberts175/176 and their negative controls; mikecann509, prior symmetric family; Chen/Cheung/Yiu, primary testing method.

Against return #72 archived data and the served reference, all other stdout bytes match the original comparator artifact and j=10..34 still reports NO DIFFERENCES. A fixture in a directory with spaces passes, altered runtime/worker metadata leaves stdout unchanged, an altered prime count exits 1, and missing input fails.

Archived return #74 inputs still print ALL OVERLAPPING ROWS AGREE; every other output byte matches after those three timing edits. Changing all three elapsed values leaves stdout unchanged, including the prime/twin counts and 9591 zones. A margin below 1 exits 1, and missing input fails. This repairs the comparator only, not another 1e10 sweep.
