Pull request overview
This PR relaxes the validation check for LoRA foundation weight files from a byte-for-byte comparison using diff -q to a size-only comparison. The change is motivated by intermittent test failures on CI that may be related to file truncation or memory issues, as referenced in PR #16876.
Changes:
- Replace
diff -qcommand with size comparison usingstatfor checking foundation weight files - Add TODO comment acknowledging that proper content validation (deserializing and checking fields) should be implemented in the future
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Relaxing the file comparison from byte-for-byte equality (using diff -q) to only size equality significantly weakens the validation. Files of the same size can have completely different content. While the TODO comment acknowledges this should be improved, this change means the test will pass even if the foundation weights are corrupted or different, as long as they're the same size. Consider whether this adequately addresses the root cause of the intermittent failures, or if it's merely masking a real problem. If file truncation or corruption is suspected (as mentioned in PR #16876), a size-only check won't catch that if both files are truncated to the same size.
