Two product lines, named to make scope obvious to buyers: - 🔒 SilverMetal OS — we ship the operating system or ROM (Linux, Pixel, Samsung-unlocked, Motorola-unlocked) - 🛡️ SilverMetal Enhanced — we harden the OS the device already runs (Windows, macOS, iOS, generic Android) Repo alignment: - SilverVPN already exists as a SilverLABS product (server + MAUI client + Linux client + tunnel service). stack/vpn/ is now an integration pointer rather than a re-scaffold; per-platform READMEs reference it. - SilverApple is deprecated; SilverMetal Enhanced — iOS supersedes it. Migration step added as roadmap milestone 3I.1. - SilverDROID name clash explicitly noted as unrelated (it's the SilverSHELL AppStore Android client, not an Android ROM). - SilverChat may overlap with SilverVPN.Client.Chat; alignment decision added as roadmap milestone 1.1.1. Roadmap restructured: phases now track the OS/Enhanced split. Platform matrix re-sectioned and decision flowchart updated. README rewritten around the two-product-line framing.

# Roadmap
|
|
|
|
Milestone-driven, no calendar dates (those slip; milestone gates don't). Each milestone has a definition of done. We don't move on until the previous milestone is met.
|
|
|
|
The two product lines (**SilverMetal OS** and **SilverMetal Enhanced**) share the same roadmap because they share the SilverLABS Application Stack and the same supporting infrastructure. They diverge in delivery format only.
|
|
|
|
## Phase 0 — Foundation (current)
|
|
|
|
**Goal**: get the architecture, threat model, and product principles documented and reviewed before writing OS code.
|
|
|
|
| # | Milestone | Done when |
|
|
|---|---|---|
|
|
| 0.1 | Repo scaffold | Directory tree + per-platform stubs + per-stack stubs in place |
|
|
| 0.2 | Umbrella docs | `README.md` + `docs/{threat-model,design-principles,platform-matrix,roadmap,trust-model}.md` complete and reviewed |
|
|
| 0.3 | Gitea repo created and pushed | `SilverLABS/SilverMetal` exists on `git.silverlabs.uk` with this scaffold |
|
|
| 0.4 | Naming framework + repo alignment locked | OS / Enhanced naming applied; SilverApple deprecation noted; SilverVPN integration scope defined |
|
|
|
|
**Status**: complete.
|
|
|

|
## Phase 1 — SilverMetal OS — Linux v1 (the MVP)
|
|
|
|
**Goal**: ship a public alpha ISO that passes our own hardening verification. This is the reference implementation; the patterns established here flow to other flavours.
|
|
|
|
| # | Milestone | Done when |
|
|
|---|---|---|
|
|
| 1.1 | Kicksecure fork builds reproducibly | `live-build` produces identical SHA256 across two clean builds |
|
|
| 1.2 | Hardening overlay applied | KSPP audit passes; Lynis ≥ 90 in CI; AppArmor strict profiles loaded |
|
|
| 1.3 | hardened_malloc integrated as system allocator | Verified active for user sessions; no regressions |
|
|
| 1.4 | Telemetry-leak test green | tcpdump on fresh-install idle for 30 min — zero packets to MS/Google/Apple/Mozilla/Canonical/Debian/analytics endpoints |
|
|
| 1.5 | LUKS2 + TPM2 PCR-bound install via Calamares | End-to-end: install → reboot → TPM unlock → desktop. Tamper test correctly falls back to passphrase |
|
|
| 1.6 | SilverBrowser v1 integrated (ungoogled-chromium rebrand) | Default browser, no Google services, fingerprint defences validated |
|
|
| 1.7 | SilverVPN integrated into image | Existing `SilverLABS/SilverVPN` Linux client + tunnel service preinstalled, always-on default; kill-switch verified |
|
|
| 1.8 | SilverSync v1 integrated (Nextcloud backbone, client-side encryption) | Contacts/calendar/files sync end-to-end; server cannot read content |
|
|
| 1.9 | Update server + signing ceremony complete | First signed update delivered through alpha channel; rollback verified |
|
|
| 1.10 | Public alpha ISO + SBOM + build attestation published | Download page live; reproducible-build instructions documented |
|
|
| 1.11 | External privacy-engineering review | One independent reviewer (Kicksecure / Whonix community) signs off on threat-model fidelity |
|
|
| 1.12 | Hardware SKU pilot batch | 10 preflashed Coreboot-supported laptops shipped and validated |
|
|
|
|
**Exit criteria for Phase 1**: alpha is publicly downloadable, all verification gates green, hardware SKU available for purchase.
|
|

|
## Phase 1.1 — Stack expansion
|
|
|
|
**Goal**: complete the SilverLABS Application Stack so v1.1 ships with the full suite.
|
|
|
|
| # | Milestone | Done when |
|
|
|---|---|---|
|
|
| 1.1.1 | SilverChat v1 — alignment review | Decide whether to pull `SilverVPN.Client.Chat` in, fork it, or scope SilverChat as a separate effort. Outcome documented in `docs/decisions/` |
|
|
| 1.1.2 | SilverChat v1 client + homeserver | Cross-platform clients functional; account-number onboarding |
|
|
| 1.1.3 | SilverDuress v1 | Linux PAM module + Android duress PIN + iOS Shortcuts/MDM trigger + Windows Group Policy + macOS profile — all verified |
|
|
| 1.1.4 | SilverKeys v1 | Bitwarden-derived client + SilverSync backend; per-platform clients |
|
|
| 1.1.5 | Atomic root experiment | ostree-based variant builds; v1.2 candidate if successful |
|
|
|

|
## Phase 2 — SilverMetal OS — Droid (Pixel + Samsung + Motorola)
|
|
|
|
**Goal**: ship the three ROM-level Android tiers.
|
|
|
|
| # | Milestone | Done when |
|
|
|---|---|---|
|
|
| 2.1 | OS — Pixel ROM (GrapheneOS-fork) | Builds, signs, OTA-updates from our infrastructure; Stack preinstalled; verified boot rooted in our key |
|
|
| 2.2 | OS — Samsung (LineageOS-fork on unlocked-bootloader models) | Supported model list published; ROM + Stack overlay |
|
|
| 2.3 | OS — Motorola (DivestOS/LineageOS) | Supported model list published; ROM + Stack overlay |
|
|
| 2.4 | Pixel preflashed pilot | 10 preflashed units shipped |
|
|
| 2.5 | Motorola preflashed pilot | 10 preflashed units shipped |
|
|

|
|
|
## Phase 3 — SilverMetal Enhanced (the four hardening packages)
|
|
|
|
**Goal**: ship Enhanced packages for Windows, macOS, iOS, and generic Android.
|
|
|
|
The four Enhanced flavours can be developed largely in parallel since they share the SilverLABS Stack and don't depend on each other.
|
|
|
|
### 3W — Enhanced — Windows
|
|
| # | Milestone | Done when |
|
|
|---|---|---|

|
| 3W.2 | Hardening installer (PowerShell/EXE) | Applies Group Policy, AppLocker, Defender ASR, removes Edge/Cortana/Store, blocks telemetry hosts |
|
|
| 3W.3 | Stack ports for Windows | SilverBrowser/Sync/etc. native Windows builds, signed with our cert. SilverVPN MAUI Windows client integrated |
|
|
| 3W.4 | BitLocker + TPM enforcement automated | Installer ensures BitLocker enabled with TPM-bound recovery |
|
|
| 3W.5 | Windows hardware SKU pilot | Preflashed Coreboot-laptop variant with Windows + Enhanced (10 units) |
|
|
| 3W.6 | Telemetry-leak test for Windows | 30-min idle on hardened install — minimum-feasible Microsoft contact, documented |
|
|
|
|

|---|---|---|
|
|
| 3M.1 | macOS configuration profile | Signed `.mobileconfig` enforces FileVault, disables analytics/Siri, configures firewall |
|
|
| 3M.2 | macOS setup script | Idempotent script applies non-MDM hardening |
|
|
| 3M.3 | Stack ports for macOS | Universal binaries, notarised, signed |
|
|
|
|
### 3I — Enhanced — iOS (supersedes SilverApple)
|
|
| # | Milestone | Done when |
|
|
|---|---|---|
|
|
| 3I.1 | Migrate / fold any usable assets from `SilverLABS/SilverApple` | Inventory of SilverApple done; reusable parts moved into `ios/`; SilverApple repo archived |
|
|
| 3I.2 | iOS MDM profile | Signed `.mobileconfig` for personal MDM or Apple Configurator |
|
|
| 3I.3 | Stack ports for iOS | App Store releases (Browser may face Apple WebKit constraints — fall back if needed) |
|
|
| 3I.4 | Apple setup guide | Step-by-step published guide complementing the profiles |
|
|
|
|
### 3A — Enhanced — Android (generic)
|
|
| # | Milestone | Done when |
|
|
|---|---|---|
|
|
| 3A.1 | Generic Android profile installer | "Harden my Android" — Stack apps + work-profile hardening config |
|

|
|
## Phase 4 — Hardening / immutability / Tor sibling
|
|
|
|
**Goal**: post-MVP improvements; not blocking earlier phases.
|
|
|
|
- Atomic / immutable Linux variant (ostree)
|
|
- dm-verity-protected `/`
|
|
- Tor-by-default sibling product
|
|
- ARM64 / Apple Silicon Linux variant
|
|
- Coreboot tooling improvements / additional reference hardware
|
|
|
|

|
|
|
|
## Cross-cutting workstreams (always-on)
|
|
|
|
- **Security advisories** — vulnerability response process from Phase 1.10 onward
|
|
- **External audits** — annual or per-major-release third-party review
|
|
- **Documentation** — every phase's gate includes documentation update
|
|
- **Community / support** — issue tracker, support channels, response SLOs
|
|
|
|
## Phase entry/exit philosophy
|
|
|
|
- We do not start a phase until the previous one's exit criteria are met
|
|
- Cross-cutting workstreams run in parallel
|
|
- A failing verification gate blocks the phase, full stop — no shipping with known regressions
