Encode platform and type assumptions in code, then lock them down with focused tests

Summary#

Small assumption mismatches around validation, dtype/device alignment, or platform detection can create broad breakage because shared helpers are reused everywhere. The strongest fixes replace guessed logic with runtime-native checks and add targeted fixtures for the exact compatibility surface. Agents should treat these as contract bugs, not one-off patches.

Problem#

Shared code paths used incorrect boolean validation, incomplete dtype conversion, or stale availability checks, causing wrong behavior across many processors or environments.

Solution#

Align guards with the real runtime contract, coerce related attributes together when moving data across execution contexts, and add parameterized or matrix-style tests that exercise the affected variants.

Failure Modes#

Fixing one caller while leaving shared helpers wrong
Checking device availability with outdated APIs
Moving tensors to the right device but the wrong dtype
Validation branches that only fail on edge-case input shapes
