kingwl 2eed448acf feat(bash): the sandboxed executor — per-call policy carrier, denial facts, runner-failure classification
dsh-bash grows the per-call policy carrier: BashExecRequest.sandboxMode
(request-optional, spec required-but-nullable — the owner pattern; resolve()
is the one explicit defaulting step) and the BashExecutor.sandboxMode
capability fact (undefined in the base class — composition truth the tool
layer can read). dsh-bash-local carries the field verbatim and confines
nothing.

dsh-bash-sandbox extends LocalBashExecutor and hands ctx.sandbox the exact
argv it is about to spawn. A denial is a RESULT FACT (the command RAN;
result.sandbox.denied is orthogonal to exitCode/signal), classified
conservatively against the wrap own dialect; a RUNNER failure outranks
denial — foreground re-throws the structured SANDBOX_UNAVAILABLE, a settled
background task stamps sandbox.runnerFailed — so a broken sandbox never
reads as a failing command and the command never runs unconfined.
dsh-tool-bash renders the markers and teaches the model not to retry around
a policy denial; escalation and per-session switching are staged follow-ups.

# bash/ — bash capability family
The canonical three-package capability seam (see [capability seams](../../docs/rfc/implemented/architecture/2026-06-13-capability-seams.md)): 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/`](../sandbox/README.md) 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 [examples/sandbox-acp-agent](../../examples/sandbox-acp-agent/)).
