Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. Matrix3 initializes as a 3x3 identity matrix with elements stored in column-major order and isMatrix3 set to true
  2. set populates elements from 9 row-major parameters into internal column-major layout
  3. determinant accurately computes the 3x3 scalar determinant and invert calculates the inverse matrix
  4. makeTranslation, makeRotation, and makeScale construct 2D affine transformation matrices in homogeneous coordinates
  5. multiplyMatrices, multiply, and premultiply perform 3x3 matrix multiplications preserving associative properties
  6. transpose reflects matrix elements across the main diagonal in place
  7. setUvTransform creates a 2D affine transformation matrix for texture coordinates combining translation, scale, rotation, and center offset
