## VITAL — Do Not Remove

These are the backbone. Without them, the system does not boot, authenticate, update, or connect.

| Package | Why |
|---|---|
| `base` | Base system files. Removing this breaks everything. |
| `base-devel` | Build toolchain (gcc, make, etc.). Needed for AUR and from-source work. |
| `linux-cachyos` + `headers` | Custom CachyOS kernel with BORE scheduler. Boot-critical. |
| `linux-cachyos-lts` + `headers` | LTS fallback kernel. Boot-critical redundancy. |
| `linux-firmware` | Hardware firmware blobs. WiFi, GPU, NIC will fail without. |
| `amd-ucode` | AMD CPU microcode updates. Security + stability. |
| `nvidia-580xx-dkms` + `utils` + `settings` + `opencl` | GPU driver stack. Display + CUDA + ML workloads. |
| `lib32-nvidia-580xx-utils` + `lib32-vulkan-*` | 32-bit compatibility for GPU (Steam, Wine). |
| `mkinitcpio` | Initramfs generation. Boot-critical. |
| `efibootmgr` + `efitools` | EFI boot entry management. |
| `limine` + `limine-mkinitcpio-hook` + `limine-snapper-sync` | Your bootloader + snapper rollback integration. |
| `device-mapper` + `lvm2` + `cryptsetup` | Block device layer. LUKS + LVM. |
| `btrfs-progs` + `snapper` | Filesystem tools + snapshot management. |
| `networkmanager` + `iwd` | Network connectivity. |
| `openssh` | Remote access. |
| `sudo` | Privilege escalation. |
| `iptables` | Firewall backend. |
| `pacman` + `pacman-contrib` + `paru` + `yay` + `aurutils` | Package management. Without these you cannot install anything. |
| `systemd` (via `base`) | Init system. Implicit but critical. |
| `pipewire` + `wireplumber` + `alsa-*` | Audio stack. |
| `mesa` (via `base` / `plasma`) | OpenGL/Vulkan for AMD iGPU fallback. |
| `noto-fonts` + `noto-fonts-cjk` + `noto-fonts-emoji` | System font coverage. Broken UI without. |

- `neovim` / `nvim` — check with `nvim --version`
- `emacs` — check with `emacs --version`
- `idea` / `clion` / `pycharm` — JetBrains IDEs
- `android-studio` — Android dev
- `unityhub` / `godot` — Game engines
- `unreal-engine` — (unlikely, but check)

## Python Environment Note

You have **no user pip packages** (`pip list --user` returned empty). This is good — it means Python tools are either:
1. System packages (`python-*` from pacman)
2. Managed by `uv` (`.local/share/uv/python/...`)
3. In virtual environments (not shown)

If you use `uv` or `conda`, those environments are separate and not counted here.

## Rust/Cargo Note

Cargo-installed binaries:
- `aichat` v0.30.0 — CLI chat tool (redundant with `aichat-ng-bin` pacman package?)
- `wasm-pack` v0.14.0 — WebAssembly build tool

Keep `wasm-pack` if you do Rust→WASM. `aichat` may duplicate system package.

## Summary by Category

| Category | Count | Approx Size |
|---|---|---|
| **VITAL** | ~40 | ~2GB (kernel, drivers, base) |
| **NEEDED** | ~50 | ~3GB (toolchains, DE, browsers, comms) |
| **USEFUL** | ~150 | ~4GB (apps, devtools, media) |
| **IF YOU MUST** | ~150 | ~3GB (heavy/duplicate/niche) |
| **Total** | **391** | **~12-15GB** |

**Potential savings from aggressive cleanup:** 3-5GB by removing duplicates and heavy niche tools.
