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. Object3D initializes with default identity transforms, empty children list, null parent, unit scale, and auto-updating matrices
  2. Scene graph hierarchy methods add, remove, and removeFromParent maintain bidirectional parent-child references and dispatch added/removed events
  3. attach reparents a child node while preserving its absolute world-space transformation matrix
  4. localToWorld and worldToLocal accurately convert 3D coordinates between object local space and root world space
  5. getWorldPosition, getWorldQuaternion, getWorldScale, and getWorldDirection extract decomposed world transforms from matrixWorld
  6. lookAt rotates object orientation such that the negative Z axis points directly towards target coordinates
  7. getObjectById, getObjectByName, and getObjectsByProperty search scene subtrees for matching node identifiers and properties
  8. translateX, translateY, translateZ, and translateOnAxis apply relative positional offsets in local coordinates
  9. clone supports shallow and deep recursive copying and toJSON serializes the scene node hierarchy
