=150 2026-08-27 (CXXXVI) (the transport-lift wave — the two external-review rounds on the quantum structure of the seam transport graduate from the experiments tree into the load-bearing suite as v976_seam_lift_birkhoff.py and v977_transfer_unistochastic_wilson.py (suite [formula in source] , ledger [formula in source] : new rows TRANSFER.HIDDEN.CIRCULATION.01 and TRANSFER.COHERENT.WILSON.01, both ``executed half [E] / selection open [O]''; the exploration probes transfer_ birkhoff_ circulation_ probe.py 42/42 and transfer_ coherent_ wilson_ probe.py 28/28 stay in experiments/tfpt-discovery/ as the discovery record). (1) v976 — the Birkhoff fibre and the entanglement-breaking no-go. The Birkhoff (random-permutation) fibre of the seam single step [formula in source] (exact sixth root of the v221 kernel, [formula in source] bit-exact) is exactly a one-parameter line [formula in source] ; the hidden coordinate is the sign-character Fourier coefficient [formula in source] , populations are exactly [formula in source] -free, and no fibre member is chiral ( [formula in source] forced). The one-step coherence spectrum is [formula in source] and the triangle loop current is an exact eigen-observable [formula in source] — one step plus one current readout measures [formula in source] without an ancilla. On the contrast qubit the Choi partial transpose has spectrum [formula in source] : the deployed sixth-root spectrum sits exactly on the entanglement-breaking boundary because [formula in source] (mutated spectra miss by [formula in source] ); at the full three-level the family stays NPT at every tested iteration with [formula in source] , [formula in source] -independent. The no-go that sharpens DYN.UNITARY.DILATION.01: the deployed Kraus dilation [formula in source] is measure-and-prepare, hence entanglement breaking with quantum capacity [formula in source] and [formula in source] exactly — any dilation closing that contract must be a genuinely different object. Shannon KKT certificates: [formula in source] is exactly capacity-achieving for both [formula in source] and [formula in source] ( [formula in source] bit, [formula in source] bit, ratio [formula in source] ) — the surviving classical message is binary on every scale. The defect–Birkhoff value coincidence (weights [formula in source] vs the v652 ladder [formula in source] ) is recorded typed [C] with its honest multiplicity audit; the forcing functor is the named open contract TRANSFER.DEFECT.BIRKHOFF.01. (2) v977 — the unistochastic [formula in source] lift and the 5-12-13 Wilson code. [formula in source] is unistochastic: an exact [formula in source] with [formula in source] entrywise, angles forced by [formula in source] ( [formula in source] , [formula in source] , [formula in source] ), [formula in source] unique, lift set [formula in source] up to rephasing; Jarlskog [formula in source] exactly, and the real part of every Wilson plaquette is fixed by [formula in source] through unitarity — the full rephasing-invariant Wilson data is classical up to the [formula in source] orientation bit [formula in source] . The main plaquette is [formula in source] , normalized [formula in source] with [formula in source] (atoms: [formula in source] , [formula in source] , [formula in source] ); all nine plaquettes close on four Gaussian phase types with norms exclusively [formula in source] . The center bridge: [formula in source] for the v530 atom matrix, [formula in source] , and the v530 sibling quotients fail the identity — the bridge selects the atom quotient. Rationality selection: [formula in source] is rational only at [formula in source] (the deployed step hits [formula in source] exactly, so [formula in source] ); census over 238 valid family points: exactly one full-code point [formula in source] the deployed [formula in source] ( [formula in source] the preregistered [formula in source] kill). No fixed microstep: [formula in source] and a Dirichlet recurrence witness ( [formula in source] ) shows no single closed unitary generates the relaxing sequence — repeated steps require dephasing between steps, the six-step macro-gate [formula in source] (the coherent sharpening of clock-vs-walk). The PMNS near-miss stays a negative control ( [formula in source] vs [formula in source] ; [formula in source] ; no PMNS derivation). Surfaces. Research-contracts document: the DYN.UNITARY.DILATION.01 section gains the executed lift-structure sharpening, the CCC reduced-channel prose and the two former ``exploration-only'' citations of rounds DCXCVI/DCXCVII are upgraded to veri citations; origin_theory gains the honest ``what the classical transport does not determine'' paragraph next to the v221 recoverability code; tfpt_2 gains the [formula in source] bridge corollary in the v530 center-quotient block. No status marker moves; both contracts stay open; no PMNS/CP/flavor claim.)
