v0.1.0 — First Tagged Release

First tagged snapshot of FerrumOS: a bare-metal x86_64 kernel with a real desktop environment and an AI agent that runs as a genuine, capability-gated userland process — not a sandboxed API caller layered on top.

Kernel & Core

• Preemptive task scheduler with per-task context switching and priority queues
• Real userspace execution: ELF loader, ring-3 entry, per-process address spaces, on-demand page-fault lazy allocation, file-backed mmap
• Interactive shell with 35+ commands
• SMP initialization, ACPI shutdown/reboot

Graphical Desktop

• Custom compositor and window manager with a taskbar, Start-menu launcher, and movable/focusable windows
• Generic app-window framework — any userland process can own a real window via CreateWindow/PresentWindow/PollWindowInput
• Optional VirtIO-GPU 2D acceleration, additive over the Bochs VBE framebuffer path

Userland Apps

• Heliox Assistant (agent chat panel), Text Editor, Calculator, File Manager, Settings, Browser, App Store
• libferrumgui — shared no_std SDK for new apps

System Services

• Package manager (ferrumpkg): install/remove genuinely gate what can run
• Multi-user accounts with real capability swapping on login
• Read-write ext2 filesystem, RAM filesystem, VFS mount table
• Capability-based security, 5-tier confirmation model, persistent audit log, resource quotas

Networking & Hardware

• RTL8139 NIC + smoltcp TCP/IP, HTTP/1.1 and WebSocket clients
• Intel HDA audio, XHCI USB 3.0, PS/2 + USB HID keyboard/mouse

Agent Daemon (heliox-daemon)

• Bare-metal ReAct orchestrator (observe → think → act → verify → reflect)
• Multi-provider LLM support: local Ollama or cloud (OpenAI, Gemini, Claude)
• 39 tools mapped to 39 kernel syscalls
• Predictive world-model safety gate in front of every tool call, alongside the reactive Tier 3/4 confirmation gate
