Claude Code now reads the system's list of mounts more carefully. It:\n\n- spots malformed entries\n\n- recognises 9p mounts and mounts that use a `prefixpath=` option\n\n- recognises shares of other Windows drives\n\nThe sandbox's read and write protections, which control which files commands may touch, now also apply to paths inside one of these mounts.\n\n**Why**\n\nWSL users get file protections that match how their Windows drives are actually mounted, including folders inside a mount.\n\n- Area: Windows\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5"}
