0.14.0 (2026-06-14)

removed

• affine trait and feature — translate was +, shear was rotate; the layer only re-vocabularied the core

fixed

• chemistry electron_affinity signs by subshell continuity (was a grade proxy), matching NIST except nitrogen
• it_computes_ijk_product, its_an_octonion: assert the primitive product's commutativity/associativity (i·j = k, ijk = −1) instead of bailing on the non-commutativity/non-associativity the decomposition table adds back (linear_algebra_test)

added

• projection_test, curve_test, integral_test, exponential_test: line, area, and the integral as angle-first ops; wave_sum interference coverage in geocollection_test
• quaternion_test: the quaternion product factored — commutative rotor (*) and anti-symmetric wedge (a∧b = −b∧a), ijk = −1 in blade arithmetic, rotation composition order-dependent by exactly the geometric angle; plus a guard test that e3∧e1 = 0 is a dropped-blade shadow, not a broken cycle
