-# SamiOS — A Custom Arch Linux Distribution
+# SamiOS
 
-## Overview
+A custom Arch Linux distribution designed as a Windows replacement, built around voice-first interaction.
 
-SamiOS is a custom Linux distribution based on Arch Linux, designed as a
-personal daily-driver desktop OS. It ships a custom CLI (`samios`), an
-automated disk installer, a single-source-of-truth version system, and
-a voice-bridge prototype for hands-free OS control via Hermes.
-
-## Features
-
-- **Rolling release** Arch-based
-- **Custom CLI** (`samios`) for system management — version, status, update, install, remove, services, fonts
-- **Automated installer** (`samios-installer.sh`) — UEFI/BIOS, partitioning, pacstrap, GRUB, user creation
-- **VERSION single-source-of-truth** — one file drives every component
-- **Custom branding** — GRUB theme, MOTD, bashrc, zshrc, pacman welcome message
-- **Font policy** — excludes fonts with "7777" in the filename (personal branding)
-- **Voice bridge prototype** — `voice-bridge.py` listens to SamiType transcripts and routes to Hermes (command mode) or `xdotool` (dictation mode)
-- **CI** — Gitea Actions runs `make check` on pushes to `master` / `main` and on pull requests targeting those branches
-
-## Building from Source
-
-### Prerequisites
-
-```bash
-# On Arch Linux
-sudo pacman -S archiso git shellcheck
-```
-
-### Clone and Build
+## Quick Start
 
 ```bash
+# Clone
 git clone https://git.sami/sami7777/samios.git
-cd samios/packaging/archiso
-sudo ./build.sh
+cd samios
+
+# Run the full test suite (lint + tests)
+make check
+
+# Build the ISO (requires Arch Linux + archiso)
+cd packaging/archiso && sudo bash build.sh
 ```
 
-## Installation
+## Version Management
 
-### From ISO
+SamiOS uses a **single-source-of-truth** VERSION system. One file at the repo root controls the version everywhere:
 
-1. Boot the generated ISO. The ISO ships the live environment, the
-   `samios` package-management CLI, and `/etc/samios-version` (the
-   mirrored VERSION file). It does **not** ship
-   `samios-installer.sh` automatically — that script lives in
-   `packaging/scripts/` in the source repo and is invoked manually
-   after boot (or copied into the live environment first).
-2. To install SamiOS to disk from the live ISO, run the installer:
-   ```bash
-   sudo /root/samios-installer.sh    # if you copied it into the live env
-   # — or —
-   sudo bash /path/to/samios-installer.sh
-   ```
-   The installer is interactive by default; pass `--disk`, `--user`,
-   and `--password` to drive it non-interactively from automation:
-   ```bash
-   sudo /path/to/samios-installer.sh --disk /dev/sda --user sami --password ...
-   ```
+```bash
+# Change the version across all 7 components (CLI, installer, PKGBUILD, etc.)
+make version-set NEW=X.Y.Z
 
-> **Note:** `samios install` (the CLI subcommand on the live system
-> and on the installed OS) is the **package** installer — e.g.
-> `samios install firefox`. It does **not** invoke the OS installer.
-> The OS installer is the `samios-installer.sh` script.
+# Sync the canonical VERSION to the airootfs mirror
+make version-sync
 
-### Manual Installation
+# Print the current version
+make version
+```
 
-See [`docs/installation.md`](docs/installation.md) for detailed
-instructions.
+No component hardcodes a version literal — they all derive from `./VERSION` via a walk-up lookup pattern.
+
+## Makefile Targets
+
+| Target | Description |
+|--------|-------------|
+| `make check` | Run shellcheck + full test suite |
+| `make test` | Run test suite only |
+| `make lint` | Run shellcheck on all shell scripts |
+| `make version` | Print the current SamiOS version |
+| `make version-set NEW=X` | Set VERSION to X (e.g. `X.Y.Z` or `X.Y.Z-prerelease`) |
+| `make version-sync` | Mirror VERSION to `packaging/archiso/airootfs/etc/samios-version` |
+
+## Test Suite
+
+8 test suites with 85+ assertions covering:
+
+| Suite | Coverage |
+|-------|----------|
+| `test_version.sh` | SSOT invariant: one VERSION file, no hardcoded literals, all components agree |
+| `test_installer.sh` | Installer syntax, VERSION resolution, partition/format/pacstrap/bootloader logic |
+| `test_voice_bridge.sh` | Python AST, version resolution, class/method structure, imports |
+| `test_samios_cli.sh` | CLI commands, version output, help text |
+| `test_profiledef.sh` | Arch ISO profile structure and metadata |
+| `test_packages.sh` | Package list completeness |
+| `test_pacman_conf.sh` | Pacman configuration sections |
+| `test_font_policy.sh` | Font exclusion policy (no "7777" fonts) |

-## VERSION Single Source of Truth
+## Voice Integration (Phase 4)
 
-There is exactly **one** authoritative source for the release version:
-the `VERSION` file at the repo root. Each consumer resolves it via
-its own mechanism:
+SamiOS is being developed with voice-first interaction as the north star:
 
-- **`samios` CLI** (`packaging/archiso/airootfs/usr/local/bin/samios`) —
-  walks up from `$0` to find `./VERSION`, falls back to
-  `/etc/samios-version`, then to a documented placeholder.
-- **`samios-installer.sh`** (`packaging/scripts/samios-installer.sh`) —
-  walks up from `$0` to find `./VERSION`, falls back to
-  `/etc/samios-version`, then to a documented placeholder. Same
-  algorithm as the CLI it emits.
-- **`voice-bridge.py`** (`packaging/scripts/voice-bridge.py`) —
-  walks up from its own location to find `./VERSION`, falls back to
-  `/etc/samios-version`, then to a documented placeholder.
-- **`profiledef.sh`** (`packaging/archiso/profiledef.sh`) —
-  walks up from `$0` to find `./VERSION`, then to the documented
-  placeholder. (No `/etc/samios-version` fallback — this runs at
-  ISO *build* time, not at runtime.)
-- **`PKGBUILD`** (`packaging/packages/samios-branding/PKGBUILD`) —
-  reads `$startdir/../../../VERSION` first, falls back to
-  `../../../VERSION`, then **fails loudly** with `exit 1`. There is
-  no walk-up and no placeholder — the SSOT invariant is absolute: a
-  release build without VERSION is a build error.
-- **`.bashrc` / `.zshrc`** (in the airootfs overlay — run in the live
-  ISO when root opens a shell) — read `/etc/samios-version` directly;
-  fall back to the documented placeholder. (No walk-up: the live ISO
-  ships `/etc/samios-version` via `make version-sync`. Note: the
-  installer does **not** copy these root dotfiles to installed
-  systems — it writes its own `/etc/bash.bashrc` instead.)
+- **`voice-bridge.py`** — Prototype bridge connecting SamiType STT to system commands
+- Supports command mode ("Computer, open Firefox") and dictation mode
+- Routes to Hermes for complex queries
+- See `docs/voice-integration-architecture.md` for the full design
 
-The `test_version.sh` suite enforces this invariant: any X.Y.Z literal
-introduced into a production file fails CI. To bump the version:
+## CI/CD
 
-```bash
-make version-set NEW=<your-version>
-```
+Gitea Actions pipeline runs on every push to master:
+1. Shellcheck on all shell scripts
+2. Python AST validation (voice-bridge.py)
+3. VERSION SSOT consistency check (canonical = mirror = PKGBUILD pkgver)
+4. Arch ISO profile structure validation
+5. Full test suite (`make check`)
 
-That edits `./VERSION` and mirrors it into
-`packaging/archiso/airootfs/etc/samios-version` (the on-system anchor
-that installed systems read at runtime). Then commit and push.
+## Branding
 
-If you prefer editing manually:
-
-```bash
-# Write your target version to the SSOT file:
-echo "<NEW>" > VERSION
-# Mirror into the airootfs overlay:
-make version-sync
-# Verify the SSOT invariant still holds:
-make check
-```
-
-(The exact X.Y.Z string is intentionally omitted from this README —
-the version lives in the `VERSION` file, not in documentation.)
-
-## Makefile Targets
-
-```bash
-make help           # Show all targets
-make version        # Print current SamiOS VERSION
-make version-set NEW=<NEW>  # Bump VERSION (semver-ish, X.Y.Z[-suffix])
-make version-sync   # Mirror VERSION into the airootfs overlay
-make test           # Run the test suite
-make lint           # Run shellcheck on all shell scripts
-make check          # Run lint + test (CI entry point)
-make build          # Build the SamiOS ISO (requires archiso + root)
-make clean          # Remove build artifacts
-```
-
-## Test Suite
-
-The test suite lives under `tests/` and is wired into
-`tests/run_tests.sh`. It contains **142+ assertions across 8 test files**:
-
-| Test file | What it covers |
-|-----------|----------------|
-| `test_profiledef.sh` | archiso profiledef.sh — script presence, package lists, hooks |
-| `test_packages.sh` | package list shape and required packages |
-| `test_pacman_conf.sh` | pacman.conf configuration |
-| `test_samios_cli.sh` | the installed `samios` CLI — syntax, --help, version, status, fonts |
-| `test_font_policy.sh` | 7777-exclusion font policy |
-| `test_version.sh` | VERSION single-source-of-truth — 55+ assertions across all 7 components |
-| `test_installer.sh` | `samios-installer.sh` — syntax, SSOT, heredoc-emitted CLI |
-| `test_voice_bridge.sh` | `voice-bridge.py` — 20 hermetic behavioral assertions |
-
-Run them with:
-
-```bash
-make test           # just the tests
-make lint           # just shellcheck
-make check          # both (the CI entry point)
-```
-
-Individual tests can be run directly:
-
-```bash
-bash tests/test_voice_bridge.sh --verbose
-```
-
-## CLI Tool
-
-The `samios` command provides system management:
-
-```bash
-samios version   # Show SamiOS version
-samios status    # Show system status (disk, memory, network)
-samios update    # Update system packages
-samios install   # Install a package
-samios remove    # Remove a package
-samios services  # List running services
-samios fonts     # Check installed fonts and the 7777-exclusion policy
-samios help      # Show all commands
-```
-
-The CLI walks up at runtime to find `./VERSION` (or `/etc/samios-version`
-on a freshly installed system) so the version is never duplicated.
-
-## Voice Bridge (Prototype)
-
-`packaging/scripts/voice-bridge.py` is an early prototype of the
-voice-to-Hermes pipeline. It listens for transcripts on stdin
-(eventually from SamiType's STT socket), parses them, and:
-
-- If the transcript starts with the wake word **"computer"**, strips the
-  wake word and POSTs the remainder to the Hermes API at
-  `http://localhost:8765/command`.
-- If the transcript is **"start dictation"**, enters dictation mode and
-  routes subsequent phrases to `xdotool type` (with `xdotool key` for
-  dictation commands like "new paragraph", "tab", "scratch that").
-- If the transcript is **"stop dictation"**, exits dictation mode.
-
-The script also exposes `--version` / `-V` which prints
-`SamiOS voice-bridge v<VERSION>` — the version comes from the same
-`./VERSION` walk-up resolver used by every other component.
-
-The bridge is a **prototype**: it does not yet connect to a real
-SamiType socket, does not implement TTS feedback, and uses
-`localhost:8765` as a placeholder Hermes endpoint. See
-[`docs/voice-hermes-pipeline.md`](docs/voice-hermes-pipeline.md) and
-[`docs/voice-integration-architecture.md`](docs/voice-integration-architecture.md)
-for the design direction. The 20 behavioral assertions in
-`tests/test_voice_bridge.sh` guard the version SSOT, the wake-word
-routing, the dictation mode state machine, and the documented fallbacks.
-
-## Font Policy
-
-SamiOS excludes any fonts with "7777" in the filename as these are
-personal branding fonts. `samios fonts` enforces this at runtime; the
-CI test `test_font_policy.sh` enforces it at build time.
-
-## Development
-
-This project is under active development. See
-[`docs/roadmap.md`](docs/roadmap.md) for planned features and the
-current phase, and [`docs/developer-guide.md`](docs/developer-guide.md)
-for build/test/release workflows.

+# SamiOS desktop overlay packages
+# This file lists packages for the desktop variant of SamiOS.
+# It is used IN ADDITION TO packages.x86_64 (which stays minimal/CLI-only).
+#
+# To build a desktop ISO:
+#   1. Create a temporary profile directory
+#   2. Copy the base archiso profile into it
+#   3. Merge both package lists into packages.x86_64:
+#      cat packaging/archiso/packages.x86_64 \
+#          packaging/archiso/packages.x86_64.desktop \
+#      > /tmp/desktop-profile/packages.x86_64
+#   4. Build:
+#      sudo mkarchiso -w work/ -o out/ /tmp/desktop-profile/
+#
+# All packages are from the standard Arch repos (core/extra).
+# NOTE: Verify availability before building — Arch repos change.
+#       Run: pacman -Ss <package> to check.
