Summary of changes

helpers.is_remote_path used urlparse().scheme and only excluded a drive letter followed by a backslash. On Windows, basepaths written with forward slashes (C:/data) were misclassified as remote URLs, so RemotePlugin tried to fetch a local file over HTTP.

Align is_remote_path with parse_scheme_and_format: a scheme shorter than two characters is not a real URL scheme (empty or single-letter drive letter), so return False.

Root cause

urlparse('C:/data').scheme returns 'c'. The original code checked path.lower().startswith(scheme + ':\') which only matched backslash paths. Forward-slash Windows paths slipped through and were treated as remote. parse_scheme_and_format already handled this via if len(scheme) < 2. The two helpers disagreed about the same path.

Verification

• is_remote_path('C:/data') now returns False (was True)
• is_remote_path('C:\data') still returns False
• is_remote_path('https://example.com/data.csv') still returns True
• 26 tests pass in frictionless/helpers/__spec__/test_general.py
• ruff check passes on changed file

Closes #1872
