Sorry, something went wrong.
Fix targeted gvproxy kill to use tracked PID from runtime state instead of pkill, gate diagnostic dump behind OPENSHELL_VM_DIAG env var, stream SHA-256 hashing to avoid buffering entire files, clarify operator precedence in env var validation, replace hand-rolled JSON parser with serde_json, deduplicate required_runtime_lib_name(), and add openshell-vm to AGENTS.md architecture table.

- Gate krun_add_net_unixgram FFI type, struct field, and VmContext method behind #[cfg(target_os = "macos")] to eliminate dead_code warnings on Linux - Add krun_add_net_unixstream FFI binding and add_net_unixstream VmContext method for Linux SOCK_STREAM networking via gvproxy QEMU listener - Switch gvproxy launch flags: -listen-qemu (Linux) vs -listen-vfkit (macOS) - Add recover_stale_kine_db: removes corrupt or bootstrap-locked SQLite kine database before boot so k3s always starts with a clean schema - Drop version segment from rootfs and runtime cache paths to avoid stale directories accumulating across upgrades - Improve build-libkrun.sh: two-phase kernel config merge using merge_config.sh and auto-detect LIBCLANG_PATH for clang-sys on Debian/Ubuntu - Ensure libkrunfw.so.5 soname file is present alongside versioned artifact - Add bundle-vm-runtime.sh task and vm:bundle-runtime mise target - Pin AGENT_SANDBOX_IMAGE to updated digest - Add pyelftools dev dependency

Summary
Adds the
openshell-vmcrate — a new microVM runtime that uses libkrun to boot lightweight VMs with hardware isolation. On macOS ARM64 it leverages Apple's Hypervisor.framework; on Linux it uses KVM. This provides a single-binary alternative to the Docker/k3s-based gateway deployment.Changes
