Group modules by responsibility:
- _runtime/: internal C ABI layer (loader, ctypes_bindings,
prepared, tensor_view); underscore prefix signals non-public API
- testing/: test utilities split by concern (assertions, benchmark,
profiler) instead of mixed in top-level files
- ops/__init__.py: per-operator registration; adding a new operator
only requires one line here, not touching the top-level __init__
- operator_runtime/__init__.py: thin gateway that re-exports from ops/
External import paths for tests are unchanged:
operator_runtime.testing still exports require_cuda, assert_close,
cuda_time_ms, PerformanceResult
