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.

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