* feat(podman): add Podman compute driver for rootless sandbox management Adds openshell-driver-podman, a new compute driver that manages OpenShell sandboxes as rootless Podman containers via the Podman REST API over a Unix socket. Enables local workstation sandboxes without Kubernetes. Driver features: - Bridge networking with ephemeral host-port mapping for rootless SSH reachability - Named volumes for workspace storage, Podman native health checks, GPU via CDI - Supervisor binary sideloaded via image volume mount (BYOC-compatible) - SSH handshake secret injected via Podman secrets API (not plaintext env) - Typed ContainerSpec structs, input validation, and path-traversal guards - Cgroups v2 required; fails fast on v1 hosts - Bounded event stream buffer; watch stream reconnection handled by server watch_loop - Graceful shutdown and standalone driver binary with gRPC bridge Rootless-specific fixes: - Skip drop_privileges when user namespace lacks SETUID/SETGID/DAC_READ_SEARCH caps - Add /run/netns tmpfs mount for ip netns in rootless containers - Use secret_env map (not secrets array) for env-var injection in libpod API - Resolve SSH endpoint to 127.0.0.1:<host_port> instead of unreachable bridge IP Server/sandbox hardening: - Split loopback and link-local SSRF gates; Podman/VM drivers allow loopback - Close SSRF bypass in SSH tunnel Host path by resolving DNS before connecting - Prevent OPENSHELL_* env var override by user-supplied spec environment maps - Disable SQLite pool idle_timeout/max_lifetime for in-memory databases - Emit deleted_event on 404-during-inspect instead of regressing sandbox phase - Key delete cleanup by stable sandbox_id to survive container label drift CLI fixes: - Restore --name as a named flag on sandbox create (not positional) - Fix exec command arg parsing to not consume sandboxed-command flags - Propagate SSH verbosity via OPENSHELL_SSH_LOG_LEVEL Build tooling: - Add tasks/scripts/container-engine.sh: auto-detects Podman or Docker, exposes unified ce_* helpers; all build/cluster/VM scripts updated to use it - Add docker:build:supervisor mise task for standalone supervisor image - Add openshell-driver-podman to Dockerfile.images pre-fetch/build stages - Add e2e/rust/e2e-podman.sh and e2e:podman mise task for full lifecycle testing Signed-off-by: Adam Miller <admiller@redhat.com> * fix(driver-podman): derive grpc endpoint from server bind port When a user starts the gateway on a non-default port (e.g. --port 8081), sandbox containers were receiving OPENSHELL_ENDPOINT pointing at the default port 8080. The driver's auto-detection fallback read OPENSHELL_BIND_ADDRESS from the environment, which was stale or unset, and fell back to DEFAULT_SERVER_PORT. Add gateway_port to PodmanComputeConfig and thread config.bind_address.port() from the server into the driver so the fallback uses the actual listening port. Remove the OPENSHELL_BIND_ADDRESS env var read and the extract_port_from_bind_address helper which are no longer needed. Add --gateway-port / OPENSHELL_GATEWAY_PORT to the standalone driver binary for parity when the driver is run outside the embedded server path.

The prior safety comment incorrectly claimed Cargo runs tests single-threaded. Update debug-openshell-cluster skill to accurately document the DNS proxy strategy (setup_dns_proxy + public DNS fallback) and clarify the separation between cluster DNS and sandbox agent DNS enforcement. Signed-off-by: Adam Miller <admiller@redhat.com> * fix(e2e): resolve CI failures in auth timeout, test harness, and formatting - Short-circuit browser_auth_flow when OPENSHELL_NO_BROWSER=1 instead of waiting the full 120s AUTH_TIMEOUT for a callback that never arrives - Add timeout to SandboxGuard::create() and create_with_upload() to prevent indefinite hangs (matches create_keep() which already had one) - Add missing '--' separator in no_proxy test before command args - Add #![cfg(feature = "e2e")] gate to sandbox_lifecycle.rs - Run cargo fmt on openshell-driver-podman - Refine cluster DNS docs for Podman in debug-openshell-cluster skill Signed-off-by: Adam Miller <admiller@redhat.com> * refactor(server): remove allows_loopback_endpoints from ComputeRuntime SSRF protection is now handled at the network and proxy layers (openshell-core net.rs, openshell-sandbox proxy.rs) rather than requiring per-driver flags on ComputeRuntime. Update architecture docs to reflect supervisor relay SSH transport and add rootless networking deep-dive.
