An observed speedup is scoped to this adapter, browser, sample count, and timing method. It is not a universal hardware claim and never replaces the canonical geometry receipt.
WHY A NEW CONTRACT?
Associativity has rules.
The v2.6 sequential path applies modified Gram–Schmidt after every step. That nonlinear projection cannot be inserted into an associative prefix operation without changing the mathematics. The parallel contract therefore composes midpoint Rodrigues SE(3) transforms in a named doubling order and validates that order independently.
