Technical Notes

Browser output writes now use root-bound, fd/inode-verified commit flow.
Install + skills path checks now share canonical in-base validation to reduce drift and close equivalent escape surfaces.
Added regression coverage for symlink-rebind and root-bound source-path write behavior.
