Keep forwarded toolchain homes accessible inside the jail
Forwarding RUSTUP_HOME and CARGO_HOME exposes host paths such as ~/.rustup and ~/.cargo to local jailed commands, but the jail only grants the workspace and explicitly configured mounts. A command using the inherited rustup/cargo toolchain can therefore fail with permission errors or be unable to locate its toolchain. Either add narrowly scoped mounts for these directories with the required access mode, or configure toolchain homes inside an accessible sandbox directory instead of forwarding the host values.
Additional e2e observation
Cover toolchain-home passthrough with an end-to-end shell run
[RULE] e2e-uncovered
The behavioural change makes sandboxed shell commands inherit RUSTUP_HOME and CARGO_HOME on the host. The only test exercising it is crates/openhuman-core/src/sandbox/ops_tests.rs, a colocated Rust test that needs cargo installed on the runner and silently skips otherwise ("SKIP cargo: not installed on this host"), and the docs add only a manual RELEASE-MANUAL-SMOKE step. No Playwright spec or Rust E2E job drives a shell command through the agent sandbox and asserts the toolchain environment, so the candidate e2e hit (tests/agent_harness_e2e.rs mentioning tools_agent) is lexical only. An end-to-end test would have to run a shell command via the running agent (e.g. extend app/test/e2e/specs/tool-shell-git-flow.spec.ts or the Rust mock-backend E2E) with RUSTUP_HOME/CARGO_HOME set in the harness environment and assert the command observes them, so that a regression in either spawn path fails CI instead of shipping.

The native jail resolves default toolchain grants in sandbox/grants.rs before building its command. These include the Rust home and Cargo executable/configuration paths as read-only, Cargo registry/git paths with their existing write access, and read-only /usr/local and /opt roots. The pinned CI homes /usr/local/rustup and /usr/local/cargo fall within that existing system-root grant.
ShellTool::run_sandboxed passes RuntimeConfig::default() to grant resolution. The added sandboxed_shell_forwards_host_toolchain_homes_and_confines_writes E2E captures the installed homes before activating its private HOME, then maps its HOME toolchain entries to the captured Rust home and Cargo executable directory. It exercises this existing default policy and credential floor.
The test drives web-chat RPC through the running sandboxed orchestrator and real shell tool, asserts the observed host homes, Cargo startup, scratch files, workspace writes and outside-write denial, and checks delivery of the shell result to the subsequent model request.

Grant or isolate the forwarded toolchain homes
execute_local_jail now sets RUSTUP_HOME and CARGO_HOME to the host values, commonly paths such as ~/.rustup and ~/.cargo, but the jail only grants the workspace and explicitly configured mounts. A local Landlock command therefore receives paths it cannot read or write; rustup shims and cargo operations can fail with permission errors or be unable to locate the installed toolchain. Either add narrowly scoped mounts for these directories with an appropriate access mode, or avoid forwarding them and configure toolchain homes inside an accessible sandbox directory.

The native-jail grant resolver already includes the default Rust/Cargo toolchain paths and read-only system roots /usr/local and /opt. The pinned CI homes are covered by /usr/local; this change retains those grants while forwarding the host's selected homes. The new agent-shell E2E exercises default grant resolution through its private HOME toolchain entries, including Cargo startup and write confinement.

Skip or provision missing host toolchain homes
On a Linux runner with Cargo installed system-wide, or with rustup configured outside the conventional home directories, these assertions panic before the orchestrator is started. The test therefore makes the Linux test suite depend on RUSTUP_HOME and CARGO_HOME both existing as directories, even though those paths are not required by Cargo's installation contract. Detect the actual toolchain layout and skip when the required host homes are unavailable, or provision isolated homes for the test instead of failing the suite during setup.

On local machines without initialized Rustup/Cargo homes, the portable test reports SKIP with a reason. In CI (GITHUB_ACTIONS=true), the required toolchain prerequisites are enforced and missing components fail explicitly. Once the selected toolchain is initialized, execution faults remain hard failures. This keeps local test discovery portable while preserving strict CI coverage for the real shell path. 1 real agent-shell E2E and 77 sandbox regressions passed, with 0 failures and 0 ignored; https://github.com/SayrWolfridge/openhuman/actions/runs/37570238760.

Keep forwarded toolchain homes accessible inside the jail
This test only links the temporary HOME entries to the real host Rust directories; it does not change the sandbox implementation that must make those locations available. The underlying forwarded RUSTUP_HOME and CARGO_HOME handling therefore remains unresolved, and the production shell path can still fail when Cargo/rustup is invoked inside the jail. Update the sandbox's explicit grants or forwarding mechanism rather than relying on this fixture's symlinks.
[RULE] sandbox-path-isolation ·
There was a problem hiding this comment.
The shell test now stages toolchain inputs at isolated absolute paths outside HOME and the standard system roots, then exercises the real jail against those paths. It captures the active Rustup selection and Cargo version and verifies the shell uses the same toolchain; the fixture has a hardlink/copy fallback for portable staging. This directly exercises the configured-path grant policy. 1 real agent-shell E2E and 77 sandbox regressions passed, with 0 failures and 0 ignored; https://github.com/SayrWolfridge/openhuman/actions/runs/37570238760.

Grant or isolate the forwarded toolchain homes
The fixture works around the missing host-toolchain grants by placing symlinks under the temporary HOME. That does not provide a production-safe policy: canonicalizing these links can either deny the toolchain entirely or grant access to the real host directories without a narrowly defined read/write boundary. The sandbox should explicitly grant the required toolchain paths with the intended permissions, or provide isolated copies, and the test should exercise that implementation rather than install symlink-based privileges.
[RULE] sandbox-path-isolation ·
There was a problem hiding this comment.
Grant resolution canonicalizes configured and default/fallback Cargo roots and applies the credential floor to credential paths, including credentials.toml. Rustup read-only candidates are filtered for overlap with Cargo roots or credentials. Cargo read-write candidates are rejected when they overlap bin, config.toml, config, or env, preserving those entries as read-only. Regression cases cover registry-to-Cargo-root overlap, config-to-credentials overlap, a broad Rustup parent, and registry-to-bin read-write promotion; the dedicated external-cache alias remains admitted. Generic extra and system grants retain their existing behavior. 1 real agent-shell E2E and 77 sandbox regressions passed, with 0 failures and 0 ignored; https://github.com/SayrWolfridge/openhuman/actions/runs/37570238760.

Make the toolchain-home probe set the homes it asserts
The probe asserts the sandboxed process sees exactly the host's RUSTUP_HOME/CARGO_HOME, but when the test host has neither variable set, unwrap_or_default() makes both the expected values and the sandboxed output empty strings, so the assertion passes without exercising the HOST_TOOLCHAIN_ENV_PASSTHROUGH forwarding at all — the very contract this test claims to pin. Set the two variables explicitly for the duration of the test (the e2e test does this with EnvVarGuard::set_to_path) so the assertion actually fails if the passthrough regresses.

Grant or isolate toolchain homes forwarded from outside HOME
The new e2e test covers the HOME-based defaults only: it comments 'The shell's default local jail grants HOME/.rustup and HOME/.cargo/bin' and works by symlinking the host homes into the fixture's temporary HOME. For a user who sets RUSTUP_HOME or CARGO_HOME explicitly to a path outside HOME — the very case the passthrough exists for, per the docs' isolated-profile smoke step — the variable is now forwarded into the Landlock jail but the jail has no grant for that path, so Cargo fails with a confusing permission error instead of either working or not receiving the variable at all. Either extend the jail grants to include the configured homes when they are forwarded, or only forward a home variable when its path falls under an existing grant.

With toolchain_homes enabled, configured absolute Rustup and Cargo paths pass through canonicalization and the existing credential floor.

Keep forwarded toolchain homes accessible inside the jail
This row now claims that the real Landlock and agent-harness tests cover forwarded custom toolchain homes, Cargo startup, and write confinement, but the prior review found that forwarded homes are not accessible inside the jail. Unless the harness provisions or explicitly grants those homes, the named E2E cannot demonstrate the behavior claimed here and the ✅ status is misleading.

Grant or isolate forwarded toolchain homes
The documentation says the integration and E2E layers verify selective access to forwarded toolchain homes, yet the earlier finding that those homes must be granted or isolated remains unresolved. A test that cannot access the forwarded paths cannot validate read-only access, cache writes, or Cargo startup for them.

Grant or isolate toolchain homes forwarded from outside HOME
The row claims coverage for custom homes, including homes outside the normal HOME tree, but the earlier review found that forwarded homes outside HOME are not granted or isolated correctly. Those inputs therefore do not receive the selective-access behavior asserted by this matrix entry.

Preserve non-UTF-8 toolchain-home paths
On Unix, tempfile::tempdir() can produce a path containing invalid UTF-8 when the temporary-directory root has such a name. Both to_str().unwrap() calls then panic before the sandbox is exercised, even though environment variables accept arbitrary OS strings. Pass the paths directly (or use to_string_lossy() consistently) so this test works on all valid Unix paths.

Make the toolchain-home probe set homes it asserts
The matrix cites landlock_custom_toolchain_homes_keep_selective_access as verification of custom-home behavior, but the prior review found that the probe does not actually set up the homes it later asserts. That means the named test cannot substantiate the read-only and cache-write claims in this row.

Skip or provision missing host toolchain homes
The claimed coverage depends on host toolchain-home paths existing, but the earlier review found that missing host homes are not skipped or provisioned. On a machine without those paths, this fixture cannot exercise the behavior described by the matrix, so marking the feature fully covered is incorrect.

Provision missing Cargo homes before granting them
A configured absolute CARGO_HOME is passed here, but canonicalization fails when the home has not been created yet, so the function silently returns without granting it. The same existing-path requirement applies to its registry and git children. In a fresh environment, jailed Cargo cannot create its cache or checkout directories because neither the home nor those writable subdirectories are admitted. Create the required directories before canonicalizing/granting them, or explicitly provision them outside the jail.

Summary
RUSTUP_HOMEandCARGO_HOMEfor native host-local shell commands.toolchain_homesis enabled, grant explicitly configured absolute Rustup and Cargo homes through the existing credential floor.Problem
The CI image installs Rust under
/usr/local/rustupand Cargo under/usr/local/cargo. The native command builders clear each child environment and rebuild it from an allowlist that omittedRUSTUP_HOMEandCARGO_HOME. With Rustup falling back to/github/home/.rustupin the Landlock fixture, Cargo receives a permission-denied error and the Rust coverage lane fails. The original repair forwards the host-selected homes through both native command builders. A second grant gap affects explicitly configured absolute homes outside HOME and the standard system roots; the jail needs scoped access to those selected paths.Solution
Both native command builders forward the host-selected
RUSTUP_HOMEandCARGO_HOMEafter clearing the child environment. Docker retains its image-provided toolchain environment. Whentoolchain_homesis enabled, grant resolution reads UTF-8 environment values withstd::env::varand admits explicitly configured absolute existing paths through the current credential floor. Relative values continue to be forwarded to the child and are excluded from grant admission. Rustup receives read-only access, with candidate paths filtered for overlap with Cargo roots and credential paths. Cargo roots use canonical configured and default/fallback locations as overlap boundaries. Itsbin,config.toml,config, andenventries receive read-only access, whileregistryandgitreceive read-write access only when their canonical candidates do not overlap those executable/configuration entries or credential paths. Existing HOME and system grants remain available, and generic extra/system grants retain their current behavior.Grant regressions in
sandbox/grants_tests.rscover configured and default/fallback Cargo roots, canonical paths, missing and relative values, deduplication, disabled policy, credential paths includingcredentials.toml, and access-boundary overlap cases. They exercise a registry candidate overlapping the Cargo root, config overlapping credentials, a broad Rustup parent, and a registry candidate overlappingbinfor read-write access; the dedicated external-cache alias case remains covered.sandbox/ops_toolchain_tests.rschecks explicit nonempty environment values and actual jailed read-only, cache-write and Cargo-credential boundaries. The portable agent-shell fixture stages real toolchain metadata and executables outside HOME and the standard system roots, using hardlink/copy fallback; it captures the active Rustup toolchain name and Cargo version, then verifies the shell observes the same toolchain through isolated absolute paths outside HOME. On local machines lacking an initialized Rustup/Cargo toolchain, the test reportsSKIPwith its reason. WithGITHUB_ACTIONS=true, those prerequisites are required and missing components fail explicitly; faults while using the selected initialized toolchain remain hard failures. The Linux smoke checklist places the toolchain check in its Linux section before sign-off.Submission Checklist
## Related: 6.2.1, 6.2.2.### Linux, before Sign-off.Impact
Native jailed shell commands can use explicitly configured Rust toolchains outside HOME and the standard system roots when
toolchain_homesis enabled. Rustup reads its configured home; Cargo reads its executable/configuration entries and writes to its registry and Git caches. The existing credential floor, HOME/system grants, and Docker toolchain policy continue to apply.Related
