There was a problem hiding this comment.
For the normal successful in-root path, is_relative_to(root) already performs the path-ancestry work, after which relative_to(root) repeats it immediately. On the supported Python implementations this makes this hot path slower rather than faster—the full helper is measurably slower for valid paths—so retain the single relative_to() call with ValueError handling or otherwise derive the relative path only once.

💡 What: Replaced
try/except Path.relative_to()withPath.is_relative_to()bounds checking inscripts/kb/write_utils.py.🎯 Why:
is_relative_tonatively implements string comparison under the hood and is much faster than catchingValueErrorfromrelative_to()for bounds checking.📊 Impact: Reduces overhead during path validation.
🔬 Measurement: Path validation functions will execute faster on large loops.
