These issues and pull requests address crashes and failures in the @ file autocomplete feature on Windows when paths span different drives or mount points, caused by os.path.relpath() raising ValueError. Multiple fixes were proposed to skip or handle invalid cross-drive path completions.

How this cluster was grouped
  • Link evidence (partly structural links): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
  • Members outside that structural core may belong to a different underlying problem.
  • Pairwise link density 0.20: the share of item pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. 1.00 means every pair is linked.
