## Implementation Roadmap
### Stage 1: Core Safety Infrastructure (Week 1-2)
### Stage 1: Bare-Metal Hypervisor Skeleton ✅ Implemented
**Deliverables**:
- Memory safety framework with bounds checking
- Production-safe assertion system
- Thread-safe locking mechanisms
- Basic agent sandbox implementation
- Bootable bare-metal kernel for QEMU ARM virt
- Assembly startup with stack/BSS setup
- PL011 UART driver for serial output
- Build system using `arm-none-eabi-gcc`
**Code Components**:
```python
# Core safety modules
- AurelioMemorySafety
- AurelioSafetyChecks
- AurelioThreadSafeLocking
- AurelioAgentSandbox (basic)
| File | Purpose |
|------|---------|
| `kernel/arch/arm/boot.S` | ARMv7 assembly entry point |
| `kernel/arch/arm/linker.ld` | Memory layout for QEMU virt |
| `kernel/arch/arm/uart.c` / `uart.h` | PL011 UART driver |
| `kernel/kernel.c` | `kernel_main()` entry point |
| `kernel/Makefile` | Cross-compilation and QEMU launch |
| `kernel/README.md` | Build and run instructions |
**Verification**: `make run` boots the kernel in QEMU and prints:
```
Universalisos type-1 hypervisor booted.
Stage 1: bare-metal skeleton running on QEMU ARM virt.
```
### Stage 2: Code Generation Pipeline (Week 3-4)

**Status**: ✅ **Complete**
**Status**: 🔄 **In Progress**
This integration plan provides the blueprint for implementing Universalisos type-1 hypervisor patterns in Aurelio cyber-physical brain, establishing a safety-critical foundation for agent-based orchestration with real-time guarantees and hardware-level isolation.
Stage 1 (bare-metal hypervisor skeleton) is complete and boots in QEMU. The
original Python mapping has been discarded in favor of a real C implementation.
**Next Steps**:
- Implement Stage 1 safety infrastructure
- Develop code generation pipeline
- Build agent orchestration system
- Integrate hypervisor patterns for agent isolation
- Add C safety primitives (bounds checking, assertions, spinlocks)
- Add exception vector table and basic trap handling
- Implement a simple UART console shell
- Bring up a second CPU core (SMP bring-up)
- Begin Stage 2: code generation and build integration

## Project Status
**Current Phase**: Repository Creation and Environment Setup (Day 1-2)
**Current Phase**: Stage 1 — Bare-Metal Hypervisor Skeleton
This repository is being populated with the complete PikeOS ecosystem from the Nextcloud source at `cloud.portugalfuturista.org/s/devmm-arch`.
The PikeOS 5.0 ecosystem import is complete. Active work now focuses on the
Universalisos type-1 hypervisor itself, starting with a bootable bare-metal
skeleton for QEMU ARM virt.

## Hypervisor Kernel (C)
The `kernel/` directory contains the actual Universalisos type-1 hypervisor
implementation. Stage 1 is a bootable bare-metal skeleton for QEMU ARM virt:
```bash
cd kernel
make
make run
```
See [kernel/README.md](kernel/README.md) for details.
