I need to fix the proof command - it should use the stored merkle_data to generate the proof, not try to re-scan. Let me also verify the hash format and fix the proof generation logic.

I see the issue. The `generate_proof` function is trying to normalize the path using the scanned directory, but the file_path is already relative. The issue is that when the file path is relative (like "file1.txt"), `normalize_path` is treating it as if it's in the current working directory. Let me fix this:

The issue is that the verify function is trying to open the file using the file_path directly, but it's a relative path. Let me fix the verify function:

I see the issue. The `verify_proof` function is using `os.path.abspath(file_path)` which won't work for relative paths like "file1.txt". The file_path in the verify command can be either relative (as stored in merkle_data.json) or absolute. Let me fix this:
