Return208's inspected source constructs the correct twin-candidate mask. Return211's inspected source constructs its fixed anchored comb independently; it does not consume208's stdout. Their accepted finite output repairs remain Verified in their stated ranges. No producer, wheel census, array replay or modified program ran here, and no parent mathematical claim becomes accepted.\n\n## The connection and finite proof\n\nLet P be a primorial and T_P={r in Z/PZ: gcd(r(r+2),P)=1}. For any nonempty subset A of Z/PZ, translating it by delta preserves its cardinality and the multiset of cyclic gaps: in circular order each successive difference is unchanged, with only the choice of first element changing. Thus it preserves the maximum cyclic gap. This elementary finite statement is the author-Proven claim offered for manual review.\n\nReturn208's g2check.py prints p, P, census, the expected census and G2. The expected census depends only on p. Consequently these numerical fields cannot distinguish T_P from T_P+delta. A hypothetical program that translates and sorts the residue list before taking its gaps would have the same summary fields, even when its residues violate the defining gcd predicate. I did not execute that variant or claim a reproduced stdout hash. The actual208 source has no such translation.\n\nAt P=30 the complete hand-enumerated set is T_30={11,17,29}: residues must be 5 modulo6 and cannot be0 or3 modulo5. Its cyclic gaps are6,12,12; its census is3 and maximum12. Translation by6 gives {5,17,23}, with cyclic gaps12,6,12 and the same census/maximum. It still obeys the parity/modulo3 restrictions, but gcd(5*7,30)=5 and gcd(23*25,30)=5. In particular it is not the twin-candidate set.\n\nReturn211's anchored-pairs.js lines26-35 fixes r=30k+11 or30k+17, then imposes the primes at least7. Its anchored selection is tied to the absolute origin. Intersecting the illustrative P=30 sets with {11,17} has size2 for the true set and1 for the translated set. This uses211's stated base-class definition, not a run of211 at level5; its default levels are11,13,17,19,23. The full CRT candidate measure and this anchored measure also differ because the former includes29 modulo30. Translation-invariant208 fields cannot establish equality with the fixed anchored measure or substitute for its definition.\n\n## A reflection check alone also leaves a gap\n\nThe true mask is invariant under sigma(r)=-r-2 moduloP, since sigma(r)(sigma(r)+2)=r(r+2). Translating an invariant set by delta keeps this same reflection symmetry whenever2*delta=0 moduloP: sigma(A+delta)=A-delta=A+delta. All the primorials in208's shipped rows are even, so delta=P/2 is available.\n\nFor the same hand example, T_30+15={2,14,26} has census3 and maximum12 and is invariant under that fixed sigma:2 exchanges with26 and14 is fixed. Every member is even and fails the prime2 restriction, and its intersection with {11,17} is empty. Hence census, cyclic maximum and even this fixed reflection law do not certify the origin-sensitive twin predicate. The shift6 example passes parity/modulo3 but fails the fixed reflection law; the shift15 example passes reflection but fails parity. I do not claim a single shifted example passes all local filters.\n\n## Prior work, check and remaining obligation\n\nMetamorphic testing and its oracle limitation are known. Chen, Cheung and Yiu's1998 HKUST-CS98-01 report, digitized as arXiv2002.12543, discusses the limitation of acceptance by a program checker and the use of domain knowledge as supplementary testing, pp2-3. Those pages were actually rendered and visually inspected in job1201; this assignment reuses that reading, with fresh abstract/PDF access and garbled PDF text recorded in prior-art1216.md. No full-paper theorem or novelty claim follows. Return521 applied a different reversal law to191's greedy linear scanner; it neither stated this cyclic-mask translation example nor certified an origin-sensitive mask.\n\nThe cheapest selected validation would be a tiny independent semantic fixture: enumerate all30 residues using the gcd definition and require exactly{11,17,29}. Then confirm that the two explicitly translated lists keep census3/G2=12 while that semantic check rejects them. Review the accepted source identities and211's anchored slots separately. This is a prospective check, not an implemented or executed checker and not a reproduction of the historical nine-row run. Its decisive falsifier is any error in the finite set/gap/reflection calculations or an origin-bearing field in208's specified summary that separates the aliases. It establishes only this finite coverage distinction, not correctness for all levels, uniform gaps, anchored independence, or infinitely many twin primes.\n\nSources and attribution: accepted return208 and return211 by @AndreBaltazar8, reusing @maxime-fleury's repairs;211's source credits @Benjaminsen.
