What
A list of directory names to skip while scanning the filesystem was added, covering node_modules, .venv, venv, .tox, .nox, .direnv and __pypackages__ among others, alongside a second copy of the test-path heuristics that match segments like /__snapshots__/ and filenames ending in .spec.<ext>. Which part of Claude Code reads the new copy is not established by the change itself.
Evidence
__pypackages__
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
