# Brass & Sigil

Self-hosted Minecraft modpack distribution + administration system.
Three components, one repo:

```
brass-and-sigil/
├── launcher/   ← Avalonia desktop client (Windows .NET 8)
│                  Auths with Microsoft, syncs the modpack, launches the game.
├── server/     ← brass-sigil-server daemon (Linux .NET 8)
│                  Wraps the MC subprocess, exposes the admin web panel,
│                  syncs mods, runs backups + BlueMap, handles whitelist.
├── pack/       ← Modpack content
│   ├── pack.lock.json    Source of truth for mod versions / URLs / hashes
│   ├── tweaks/           Hand-written data-only tweak source
│   └── overrides/        Build output / hand-placed local files (gitignored)
├── scripts/    ← Build + deploy entry points (run from repo root)
│   ├── Update-Pack.ps1     Refresh pack.lock.json from Modrinth/CurseForge
│   ├── Check-Updates.ps1   Non-mutating "what's new?" report
│   ├── Build-Tweaks.ps1    Compile tweaks/ into pack/overrides/mods/*.jar
│   ├── Build-Pack.ps1      Generate manifest.json from the lockfile
│   └── Deploy-Brass.ps1    One-shot build + deploy everything
└── docs/       ← Operational notes, deploy runbook, schema docs
```

## Quick start

```powershell
# Pull dependencies, copy and edit the deploy profile
git clone <remote> brass-and-sigil
cd brass-and-sigil
Copy-Item scripts\deploy.config.template.ps1 scripts\deploy.config.ps1
notepad scripts\deploy.config.ps1   # fill in deploy share, SSH host, etc.

# Build + deploy everything in one go
.\scripts\Deploy-Brass.ps1
```

`deploy.config.ps1` is gitignored -- local values never get committed.

## Component reference

| Component | What it does | Technology |
|-----------|--------------|------------|
| `launcher/` | Friend-distributed client. Auths with Microsoft via WebView2 + XboxAuthNet, downloads mods, launches Minecraft. Single self-contained `.exe` published from `publish/`. | Avalonia 12 + CmlLib.Core |
| `server/` | Daemon running alongside the MC process on Linux. Hosts a Kestrel web panel for admin (cookie-auth, rate-limited), bridges RCON, runs scheduled backups + BlueMap renders, handles whitelist requests. | ASP.NET Core minimal APIs |
| `pack/` | Lockfile-driven modpack content. `pack.lock.json` resolves mod slug → URL+SHA-1; `Build-Pack.ps1` walks it and produces `manifest.json` for the launcher and the server-tool to consume. | PowerShell tooling |

## Workflow

1. **Bump mod versions:** `.\scripts\Update-Pack.ps1` (queries Modrinth + manual CurseForge entries).
2. **Sanity-check:** `.\scripts\Check-Updates.ps1` for a non-mutating availability report.
3. **Edit tweaks** under `pack/tweaks/<name>/` if you're changing recipes / loot / etc.
4. **Deploy:** `.\scripts\Deploy-Brass.ps1` -- builds launcher + server, regenerates manifest, mirrors everything to the deploy share, scp's the server binary.

## Secrets / config files

| File | Tracked? | Notes |
|------|----------|-------|
| `launcher/launcher-config.template.json` | ✓ | Empty placeholders, public-safe |
| `launcher/launcher-config.json` | ✗ | Local override; merged into the published exe at build time if present |
| `server/deploy/server-config.example.json` | ✓ | Template; rename to `server-config.json` on the server with real values |
| `server/deploy/server-config.json` | ✗ | Production config; lives on the server only |
| `scripts/deploy.config.ps1` | ✗ | Local deploy profile (paths, SSH host, share location) |
