2026-06-22 (Lean: the SEAM.EQUIV.01 composition chain formalised — the keystone residual machine-pinned to the named cited steps: FORM.SEAMEQUIV.01)
Research changelog · TFPT — Introduction and reading guide
SeamEquivChain.lean ( FORM.SEAMEQUIV.01, Lean 4, / ). A Lean 4 mirror of the v308 closing chain: the four nodes [formula in source] assembled as a well-typed composition theorem seamEquivChain, with the three cited literature steps (Kitaev free-fermion invertibility; M\"uger / Kawahigashi–Longo–M\"uger holomorphy; Conway–Sloane [formula in source] uniqueness) as named axioms and the carrier recovery gap (the OS step)
Opening source excerpt. Formulas and the full argument remain in the original document.
