CodeQL scanning results above are reporting false positives that are already contained and explained in the security table on readme.md

Error	False Positive	Codeguru	OS command injection — generate_splat_gradio.py:115,116,117	Untrusted input used in system commands	These lines set os.environ variables for AWS credentials provided by the user in the Gradio credentials tab. No subprocess or shell command is invoked with these values; they are passed to boto3.Session() which handles them safely.
Error	False Positive	Codeguru	Path traversal — generate_splat_gradio.py (multiple lines)	User-controlled input in file paths	The flagged paths in generate_splat_gradio.py (lines 584, 1780, 1791, 1801, 1902, 3841) construct S3 key strings or presigned URL parameters, not local filesystem paths. S3 key construction does not carry path traversal risk.
