Use when running ARM or RISC-V bare-metal firmware in QEMU: machine selection, -kernel ELF loading, semihosting, or GDB debugging without hardware. Not for KVM guests: use qemu-kvm.

# QEMU embedded simulation
## Contract
| Field | Bound contract |
|---|---|
| Trigger | Bare-metal or RTOS firmware needs running without a board: Cortex-M on a QEMU STM32 machine, RISC-V on `virt`, a GDB stub session, or semihosting output. |
| Authority | Read-only. Emits analysis and commands for the operator to run; no file writes, no rollback needed. No remote mutation. |
| Side effect | QEMU command lines and a verdict in chat. Nothing is written. |
| Done | The firmware boots under the chosen machine, or the blocking limitation (unmodeled peripheral, wrong machine) is named. |
## Inputs
1. Firmware image (required): an ELF or binary linked for the target machine's memory map.
