The `readDenyPaths` policy field shipped in the previous commit broke Linux confinement outright. bwrap has to create the `/dev/null` bind's mount point inside a tree its own profile has already made read-only, so it refused the entire confinement whenever the parent directory was absent — every host that has not stored a credential yet, including a fresh install: bwrap: Can't mkdir parents for /home/runner/.dsh/.env: Read-only file system which the executor correctly classifies as SANDBOX_UNAVAILABLE, so every confined bash call failed closed. Landlock cannot subtract from its own `/` read grant, so it reported `partial` enforcement on every confined call for a file it never hid, with no way to switch the denial off (schemastery fills an omitted array with `[]`, so empty and omitted were indistinguishable). A protection that breaks confinement where it works and misreports it where it does not is worse than a documented absence. Revert the field, both expressible backends, the enforcement downgrade, and the policy default; state the residue plainly in the credentials-local READMEs — file mode stops other OS users, not the model — and keep the OS-keychain provider recorded as the real answer. The narrower discipline stands: no surface hoists the credential document into `process.env`, and the model is never handed a resolved path to it.
bash/ — bash capability family
English | 中文
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, and the managed-env/output vocabulary is re-exported from the subprocess/ seam) |
ctx.bash |
bash-local/ |
Local BashExecutor implementation over the subprocess/ service (command defaulting, deadlines, terminal env, background-read merge) |
(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 schema; background processes register with the generic tasks/ runtime |
(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).
