Use literal matching for the forbidden documentation endpoint, pin lifecycle mode/content assertions to one descriptor, and inject parent races through the staged descriptor without forwarding arbitrary file-creation flags.
Close fixture-owned descriptors when Windows blocks a directory rename before open returns. Assert OS rejection preserves both settings files and releases staging handles. Move the rename-boundary injection after descriptor close so Windows exercises parent-identity validation without skipping race coverage.
Reject directory replacement after temporary file creation or staging, preserve unrelated files during cleanup, and retry settings edits observed before the final rename. Add three regression tests for the review findings.
