Copilot now supplies saved Function replacements with matching ConditionalDimension factors, so the broad override filter is unnecessary.

Use arithm-mode throughout symbolic lowering and include generated source and compiler ABI in every Operator signature. Preserve scalar component and cast-pointer result types for ordinary packed accesses. Validate focused CPU typing, JIT identity and serialization checks, plus the dependent PRO GPU arithmetic checks.
Store the picklable pointee type and indirection in standard reconstruction metadata, deriving the full ctype on demand. Remove the custom ctypes pointer reducer and cover pointer depth, equality, scope and serialization.
Resolve MPI neighbors from the execution Grid so reconstructed internal Arrays communicate between decoupler workers. Also wrap the overlong symbolic-test imports.

Return a conservative result for C-only types such as size_t instead of passing NumPy's TypeError through FP16 code generation. Cover numeric ctypes and opaque dtypes in scalar and mixed argument queries. Validation: 9 targeted OSS symbolic tests, 12 CUDA regression and adjacent tests, isort, Flake8, and Ruff.
Select the RHS precision before creating an exact-precision printer and forward normalized Operator options to dtype-specific lowering passes.
