Extend SandboxMode enforcement from bash to the filesystem tools, the sandbox RFC's deferred cross-family phase. - dsh-sandbox-policy (new, ctx.sandboxPolicy): the single home for the deployment default mode + workspaceRoot and the per-session override event, renamed bash/sandbox-mode -> sandbox/mode and moved here with its fold/setter. Decouples the bash seam from dsh-session. - dsh-fs-sandbox (new): SandboxedFileSystem extends LocalFileSystem and fences write/edit by the per-call mode (read-only denies, workspace-write contains to the workspace + temp roots via the shared writableRoots, danger passes through); reads pass through. Structured FS_SANDBOX_DENIED; in-lock parent re-canonicalization. A policy fence in trusted code, not a kernel boundary. - dsh-sandbox: the shared escalation kit (writableRoots, the strictly-wider ladder, denial/hint markers, approveEscalation) both tool families use; approveEscalation takes a structural approver so dsh-sandbox gains no approval/agent dependency, and both tools stay duplication-free. - tool-fs: write/edit advertise sandbox_permissions/justification under a confining ctx.fs, map FS_SANDBOX_DENIED to the shared [sandbox: ...] marker, and resolve the same one-approved-wider retry. - examples/acp-agent: composes sandbox-policy + fs-sandbox, drops the gating that disabled the fs stack under confined modes. RFC docs/rfc/implemented/feature/2026-07-14-cross-family-fs-sandbox.md; the old sandbox RFC's In-process/deferred/FAQ sections updated to shipped fact.
bash/ — bash capability family
The canonical three-package capability seam (see capability seams): an abstract executor interface, concrete implementations, and the model-facing tool that consumes it. All product packages.
| Package | Role | ctx key |
|---|---|---|
bash/ |
Abstract bash executor seam (interface + vocabulary; sandbox result facts carry the sandbox/ seam's mode/enforcement vocabulary) |
ctx.bash |
bash-local/ |
Local-subprocess BashExecutor implementation |
(registers ctx.bash) |
bash-sandbox/ |
Sandbox-consuming BashExecutor (wraps every command argv via ctx.sandbox, stamps denial/enforcement facts; extends bash-local's mechanics) |
(registers ctx.bash) |
tool-bash/ |
Model-facing bash/bash_output/bash_kill tool schemas |
(registers on ctx.tools) |
The interface lives at bash/bash/. bash-sandbox replacing bash-local without touching the interface or the tool is the split doing exactly what it exists for — a leaf cordis.yml picks one executor entry, plus a ctx.sandbox provider entry for the confined one (see the acp-agent example's default composition).
