Commonly assumed
A slashless pattern like *.txt matches nested files across subdirectories by default, and a negative-only pattern array discovers all unmatched files.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- fg with baseNameMatch expands slashless patterns like *.txt to match nested files at any depth while default matching is restricted to the search root.
- fg with only negative patterns returns an empty array and fg.generateTasks yields zero tasks without at least one positive pattern.
- fg.isDynamicPattern classifies static paths as dynamic when caseSensitiveMatch is false, and respects braceExpansion and extglob disable flags.
- fg.posix.escapePath and fg.escapePath escape brackets so literal directory paths with glob characters match their exact files.
- fg.generateTasks partitions positive patterns into distinct static and dynamic tasks grouped by base directory.
