SysAdmin 7d5f9cc246 chore(scaffold): initial SilverMetal program scaffold
Cross-platform privacy-hardening program. Two-layer product:
- SilverLABS Application Stack (cross-platform spine)
- Platform Hardening Profiles (per-OS, tier-honest)

Platforms: Linux (Debian/Kicksecure), Android (Pixel/Samsung/Moto/generic),
Windows (LTSC IoT), macOS (profile), iOS (MDM profile). Each flavour has
both a preflashed hardware SKU path and a self-apply "harden your existing
device" path.

Includes umbrella docs (README + threat-model, design-principles,
platform-matrix, roadmap, trust-model), per-platform and per-stack-
component README stubs, .gitignore, LICENSE.

Linux v1 ships first; Stack v1 = Browser + VPN + Sync.

# SilverLABS Application Stack
The cross-platform spine of SilverMetal. These apps replace the cloud services your device normally talks to. Same brand, same account, same data on every platform.
## Components
| Component | Status | Purpose |
|---|---|---|
| [`browser/`](browser/) — **SilverBrowser** | v1 (Linux MVP) | De-Googled, telemetry-free browser |
| [`vpn/`](vpn/) — **SilverVPN** | v1 (Linux MVP) | Always-on, no-logs VPN with our infrastructure |
| [`sync/`](sync/) — **SilverSync** | v1 (Linux MVP) | Private replacement for iCloud/Google/OneDrive |
| [`chat/`](chat/) — **SilverChat** | v1.1 | E2EE messenger |
| [`duress/`](duress/) — **SilverDuress** | v1.1 | Duress password / panic-wipe / anti-coercion |
| [`keys/`](keys/) — **SilverKeys** | v1.1 | Zero-knowledge password + 2FA manager |
| [`shared/`](shared/) — common code | ongoing | Account SDK, crypto primitives, branding |
## Account model
Users get a **SilverLABS account number** (Mullvad-style — random, no email, no name). One account → all Stack apps. Payment is processed separately (SilverDotPay / cryptocurrency option) with no link back to the account number.
## Cross-platform build philosophy
Each app is built natively per platform — no Electron sprawl where avoidable:
- **Linux**: native `.deb` + Flatpak
- **Android**: native APK / AAB
- **Windows**: native MSI / EXE (signed)
- **macOS**: universal binary `.pkg` (notarised)
- **iOS**: App Store
Where a single codebase (e.g., Tauri / Rust core) lets us hit multiple platforms with a thin native UI shell, we use it. We avoid Electron unless the cost of native is unjustifiable.
## v1 ship order
1. **SilverBrowser** — ungoogled-chromium-derived, our defaults, our update channel
2. **SilverVPN** — WireGuard-based, our exit nodes, account-number signup
3. **SilverSync** — Nextcloud-backed (server side), client-side encryption, native clients
These three ship with SilverMetal Linux v1.
v1.1 adds Chat, Duress, Keys.
## Server side
The Stack server components live in separate repositories under `SilverLABS/`:
- `silver-vpn-infra` — WireGuard exit-node infrastructure (Terraform / Ansible)
- `silver-sync-server` — Nextcloud + Radicale + Baïkal stack
- `silver-chat-homeserver` — Matrix Synapse / Dendrite
- `silver-account` — account-number issuance + auth gateway
Self-hostable counterparts are documented for users who don't want to use SilverLABS infrastructure.
