The Parity Premise Stays a Premise: Paper #54's Entry 9 Fork, Attacked from Inside

Works item D-041-080-22 (paper #54, Entry 9) at its sharpened price (packet #522, clauses (a)-(c)) by the two routes that packet named: a derivation of the parity premise as physics, or of the sever-as-double identification. Gates reproduce packet #522's exhibits digit-for-digit first: the recovered copies' verbatim price phrases, P-squared = I with eigenvalues +1 x3 and -1 x3, det P = -1, the handedness flip +0.5 to -0.5, eigenfield flux at the scar 0.000000 / 0.000000, the mixed-parity leak 4.500000 = k-squared/2 at k = 3, the pulse flux 294.3, and the sealed species' 24 pairings. Route one states five grounds for the parity premise and computes each against the sectors: regularity, finite energy (4.709563 / 4.290482 / 9.000045), action invariance and unitary evolution are all parity-blind -- they hold of both sectors, so no derivation from them can select one -- while the ground-state ground mentions parity but selects only by restating the premise as a step. Route two tests the identification's uniqueness against the record packet #522 built: the same one-sided datum supports three constructions (the double, the disjoint pair, and the datum standing alone), so selecting the double is the identification itself; the route then stops at the fence in print, the sever-instant profile being a fenced author door that is not worked, derived, or characterised anywhere in the packet. Disposition: strengthened, not closed; clauses (a)-(c) unchanged; producing test none at present, producing-count 0. Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
