Commonly assumed
Zeitwerk autovivifies a namespace module for every subdirectory in a managed root directory, treating empty folders and non-Ruby asset directories as constant namespaces.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- assert empty directories and directories containing only non-Ruby assets or hidden dotfiles do not autovivify namespace modules and raise NameError on constant access rather than resolving to Module instances
- assert loader.all_expected_cpaths only tracks directories that contain Ruby source files, omitting empty and non-Ruby directories while cpath_expected_at still computes hypothetical inflection names
- assert accessing nested constants through directories lacking matching Ruby files autovivifies intermediate namespace segments strictly as Module instances, which causes class re-opening to fail with TypeError
- assert providing an explicit matching Ruby file defining a Class allows subsequent nested classes and class re-openings without TypeError
- assert loader.eager_load walks all valid Ruby file trees and autovivifies intermediate modules while leaving empty and non-Ruby directories completely uninitialized
