fs/ - filesystem capability family

The filesystem capability seam: an abstract filesystem interface, a local implementation, and the model-facing file tools. All product packages.

Package Role ctx key
fs/ Abstract filesystem seam (interface + vocabulary + observed-file policy) ctx.fs
fs-local/ Local-filesystem FileSystem implementation (registers ctx.fs)
tool-fs/ Model-facing read/write/edit tool schemas (registers on ctx.tools)

The interface lives at fs/fs/. A sandboxed, remote, or project-scoped filesystem backend can replace fs-local without touching the interface or model-facing tool schemas.
