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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Stack — Shared
Common code shared across SilverLABS Stack components:
- Account SDK — SilverLABS account-number issuance, auth, session management
- Crypto primitives — vetted wrappers for Argon2id, AES-GCM, ChaCha20-Poly1305, X25519, Ed25519
- Branding tokens — fonts, logos, colours, design tokens
- Update client — common update-check + signature-verify code reused by all Stack apps
To be populated as each Stack component reaches a point where shared code makes sense (typically v1 → v1.1 transition).
Language / runtime choice
Default to Rust for shared crypto and account SDK code, with bindings/bridges per platform language:
- Kotlin / Java for Android
- Swift / Obj-C for Apple platforms
- C# for Windows native integration where required
- TypeScript bindings for browser extensions / web UI
Rust gives memory safety, performance, and a single source of truth for the security-critical parts.
