The three-entry cordis.yml (dsh-sandbox-local + dsh-bash-sandbox at a read-only default + dsh-approval) served over ACP: the first live approval composition. Recorded snapshot scenarios pin the wire end to end — config-options advertisement, the mode-switching arc as the suite pinned header (both switches, the prompt-section delta, one changed-by-the-user notice per knob, a confined write landing under the switched mode), and both escalation branches over scripted permissionAnswers (a grant runs confined under workspace-write; a rejection executes nothing and pins the fail-closed text). The with-key escalation e2e drives a real model + real runner + the real bridge answerer, world-verified; ci.yml snapshot lane and e2e.yml install bubblewrap so the confined replays actually execute. Both RFCs move to implemented/ (Decision/Consequences form, deferred phases tracked in their own sections), with every cross-reference flipped.

sandbox/ — process-sandbox capability family
The confinement half of the capability-seam split: an abstract provider interface and platform backends. Consumers hand ctx.sandbox the exact argv they are about to spawn and spawn the returned (wrapped) argv instead; policy (SandboxPolicy: mode + workspace root) rides each call, so different consumers confine under different policies at the same instant. All product packages.
| Package | Role | ctx key |
|---|---|---|
sandbox/ |
Abstract process-sandbox seam (the SandboxProvider contract + the mode/enforcement/policy vocabulary) |
ctx.sandbox |
sandbox-local/ |
Local backends by platform chain: Linux bwrap else the landlock-run launcher (the npm-distributed node-addon-landlock-run family, built and released from its own repository), darwin sandbox-exec/Seatbelt — multi-candidate chains functionally probed, sole candidates selected directly, verdict cached, fail-closed |
(registers ctx.sandbox) |
The seam confines SAME-WORLD subprocesses only (shared filesystem and kernel). Containers, microVMs, and remote executors are NOT backends here — they replace whole capability implementations (ctx.bash, ctx.fs) as environment-coherent groups; the boundary is recorded in the sandbox RFC.
Consumers today: bash/bash-sandbox (wraps ['bash', '-c', command]; see examples/sandbox-acp-agent for the composed leaf). In-process tools (fs/web) cannot be confined by an OS wrapper — their sandbox semantics are policy at their own seams (the sandbox RFC's cross-family phase).
