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
- numpy.asarray reuses an existing matching ndarray by default without allocation.
- numpy.asarray with copy=False raises ValueError when given a Python sequence because allocation cannot be avoided.
- numpy.array creates a copy of an ndarray by default and shares memory only when copy=False is specified.
- ndarray.astype reuses the array when dtype matches and copy=False, but allocates a converted array when dtype changes.
- numpy.shares_memory detects memory aliasing between array views and slices.
