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. assert Texture constructor wraps image in a Source instance and aliases texture.image to texture.source.data
  2. assert mutating texture.image updates texture.source.data
  3. assert Texture.clone shares the exact same Source instance with the original texture and property mutations reflect across both
  4. assert setting Source.needsUpdate increments the source version counter
  5. assert explicit Source assignment rebinds texture data and updates texture.image
