Unclear The finding does not say what anchoring protects against or what the fallback modes mean for syncing.
What
On Windows, dir-sync, Claude Code's folder syncing, now anchors its root folder through a win32_handle backend. To do this it loads an NT FFI, a way of calling Windows system functions directly. If this does not work, the anchoring either falls back to no_ffi or goes without anchoring and records a reason why.
Windows machines now take part in dir-sync root anchoring. CLAUDE_CODE_DIR_SYNC_DISABLE_ANCHORING is the setting to look at if you need to keep anchoring out of the way.
