Commonly assumed
slashless glob patterns match file basenames at any directory depth when filtering path arrays
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- minimatch.filter generates a curried predicate function for Array.prototype.filter where slashless patterns match root paths by default and match base filenames across directories when matchBase is enabled
- assert globstar pattern matches nested files across arbitrary directory depths
- assert dotfiles are excluded by default wildcard filters and included when dot is set to true
- assert negated patterns filter out matches unless nonegate is enabled to treat exclamation marks literally
- assert nocase enables case-insensitive pattern matching against file paths
- assert minimatch.defaults binds configuration options to subsequent filter calls
