Adapt the four fs packages to master's single-tsconfig build convention (lib/types outDir + types path + files allowlist), brought in by the merge. While doing so, drop dsh-tool-fs's /read//write//edit subpath plugins. They were the only subpath-export package in the tree and forced bespoke tsdown, tsconfig path, package.json files, and workspace-constraint handling that no sibling tool package (e.g. dsh-tool-bash) carries, for a focused-deployment use case no consumer needed. dsh-tool-fs is now a single root plugin that registers read/write/edit, mirroring dsh-tool-bash; the per-tool registration helpers stay internal modules the root composes. The file-context event-gate RFC is amended to record the narrowed scope.
fs/ - filesystem capability family
The filesystem stack: a provider seam (text IO + atomic mutation with an optional version guard), a local implementation, a policy gate plugin (observed-state + read-before-edit + version-guarded write/edit), and the model-facing file tools + executor. All product packages.
| Package | Role | ctx key |
|---|---|---|
fs/ |
Provider seam: text IO + atomic mutation primitives (optional version guard); owns the fs/* policy events |
ctx.fs |
fs-local/ |
Local-filesystem FileSystem implementation |
(registers ctx.fs) |
file-context/ |
Policy gate plugin: observed-state + read-before-edit + version-guarded write/edit, via the fs/* event gate |
(no service — fs/* listeners) |
tool-fs/ |
Model-facing read/write/edit tools AND the executor (reads via ctx.fs, owns read windowing, dispatches fs/*) |
(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 seam, the policy gate, or the model-facing tool schemas. The policy (file-context/) is a plugin that participates only through the fs/* event gate, not a service the tool injects — so dropping it gracefully loses the policy and leaves the unconstrained bare provider rather than breaking the tool. A deployment that loads tool-fs/ is expected to also load it.
