What

The SDK control request that registers a repository root now expands and screens the target before any filesystem access, rejecting NT-namespace paths, UNC paths, automount locations and suspicious Windows spellings, then re-checks the resolved real path against trusted network directories.

Details
  • Rejections return a generic message to the caller while recording a specific internal reason per case.
  • Applies to every use of that control request on this build, with no flag.
Evidence

register_repo_root: NT-namespace path rejected before filesystem access

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
