* Add sandbox architecture baseline Record target backend names, enforcement metadata, legacy sandbox entrypoints, and policy JSON baseline coverage for the sandbox rewrite. Add a focused sandbox smoke script with cross-platform compile checks and an opt-in real backend smoke path. Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/sandbox -run 'TestTargetBackendForPlatformBaseline|TestLegacySandboxEntrypointsAreExplicitAndExist|TestBackendPlanCarriesPhase0ManagerFields|TestCommandPlanCarriesSandboxMetadata|TestPolicyOnlyDisabledFailClosedForTargetPlatforms|TestSelectBackendChoosesPlatformAdapterWithFallback|TestBackendBuildPlanDocumentsBestEffortIsolation|TestBackendCapabilitiesReflectDisabledPolicy' Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/cli -run 'TestRunSandboxPolicyInspectTextAndJSON|TestRunSandboxPolicyJSONGoldenIncludesManagerBaselineFields|TestRunSandboxPolicyEffectiveTextAndJSON' Tested: scripts/sandbox-smoke.sh Tested: git diff --cached --check * Introduce sandbox manager and permission profile Add a normalized permission profile and sandbox manager execution request that owns target backend selection, enforcement metadata, and fail-closed validation. Route command planning and sandbox policy output through the manager boundary while keeping legacy adapters explicit as temporary integration points.

Add tests proving manager-owned selection and the compatibility wrapper agree.

Keep the helper fail-closed until enforcement is wired, and add parser tests plus smoke compilation for the new helper package.

The helper now builds the bubblewrap argv, binds its own executable for the inner stage, applies the seccomp/no-new-privs step before exec, and preserves the original command cwd path. Package Linux releases with zero-linux-sandbox next to zero so release builds use the helper directly, while local development can fall back to go run for the helper.

Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/sandbox -run TestLinuxHelperPlanPreservesRealExtraRootCwd Tested: scripts/sandbox-smoke.sh Tested: git diff --check * Add Linux Landlock helper enforcement Implement the zero-linux-sandbox Landlock helper path with fail-closed profile validation, Landlock filesystem rules, and seccomp network-deny enforcement for the fallback backend. Broaden the Linux real smoke coverage to cover helper write allow/deny, deny-read, temp writes, metadata protection, network deny, and direct Landlock fallback behavior.

Keep the existing sandbox-exec adapter path as a compatibility wrapper while adding target macos-seatbelt capability handling. Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/sandbox Tested: scripts/sandbox-smoke.sh Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/cli ./internal/tools Tested: git diff --check * Stabilize Seatbelt write carveouts Emit protected metadata and read-only write-root carveouts as explicit Seatbelt deny rules after the broad write allow. This preserves deny precedence while avoiding fragile allow-rule predicates in real sandbox-exec runs. Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/sandbox Tested: scripts/sandbox-smoke.sh Tested: git diff --check * Expand macOS Seatbelt runtime allowances Restore the platform startup allowances needed by sandbox-exec-wrapped commands under restricted filesystem profiles: executable mapping, system metadata reads, pty/device access, preferences, IPC, and standard library/runtime roots. This keeps project writes constrained to the PermissionProfile roots while preventing macOS shells from aborting before user commands run. Tested: GOCACHE=/tmp/zero-go-cache go test ./internal/sandbox Tested: scripts/sandbox-smoke.sh Tested: git diff --check * Normalize Seatbelt deny expectations in tests Build Seatbelt deny-rule expectations from normalized profile paths so the metadata ordering test matches production behavior on Windows and Unix hosts.

Add the Windows runner argument contract for command cwd, workspace roots, permission profile JSON, child environment JSON, restricted-token level, and payload command parsing. Update sandbox policy output and tests to describe the missing Windows runner instead of an unimplemented adapter.

Tested: git diff --check * Add Windows sandbox command runner Add the zero-windows-command-runner executable and wire windows-restricted-token plans to pass sandbox home, command cwd, workspace roots, permission profile JSON, child env JSON, sandbox level, and command argv. Persist Windows capability SIDs under the resolved sandbox home, select read-only or writable-root capability SIDs from the permission profile, and create a restricted token before launching the payload with CreateProcessAsUserW. Package the Windows runner next to zero.exe and extend sandbox smoke coverage to cross-build it.

Tested: git diff --check * Plan Windows sandbox ACL operations Derive a deterministic Windows ACL operation list from the restricted permission profile, including writable root allows, protected metadata deny-write entries, explicit deny-write paths, and deny-read materialization targets. The plan maps workspace and extra writable roots onto the persisted capability SIDs so the elevated setup helper can apply the same contract without reinterpreting the profile.

Tested: scripts/sandbox-smoke.sh Tested: git diff --check * Add Windows sandbox setup boundary Add the zero-windows-sandbox-setup command, setup argument parsing, deterministic ACL plan hashing, and a setup marker contract that can detect profile changes requiring refresh. Make Windows native backend discovery require both the command runner and setup helper, package the setup helper with Windows releases, and include it in sandbox smoke builds. The setup command remains fail-closed until the Windows ACL applier is wired, so it cannot create a setup-complete marker without applying enforcement.

The setup helper now installs or removes those filters transactionally before writing the setup marker, and the marker tracks the network enforcement plan so stale filters require refresh. Scoped Windows network mode remains fail-closed until the proxy exception path is implemented, so it cannot silently become open network.
