SysAdmin 0a0075ce66 docs(naming): adopt OS / Enhanced product-line framing + align with existing repos

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.

SilverMetal

Privacy-hardened devices for users who want their privacy back — on whatever platform they have.

SilverMetal is SilverLABS' cross-platform privacy-hardening program. We don't believe in "one true OS" — we meet users on the platform they actually use, and give them the strongest hardening that platform physically allows. Honestly labelled, no marketing fluff.

Two product lines

The SilverMetal program ships two distinct product lines, named to make their scope obvious to buyers:

🔒 SilverMetal OS

We ship the operating system or ROM. Full kernel-level control, our verified-boot key, our update channel. Strongest possible hardening.

SilverMetal OS — Linux (Debian/Kicksecure-based ISO) — Tier A
SilverMetal OS — Pixel (GrapheneOS-fork ROM) — Tier B
SilverMetal OS — Samsung (LineageOS-fork ROM, unlocked-bootloader models) — Tier C
SilverMetal OS — Motorola (DivestOS/LineageOS-fork ROM) — Tier C

🛡️ SilverMetal Enhanced

We harden the OS your device already runs. Configuration profiles, hardening installers, the SilverLABS Application Stack. For users who can't or won't replace their OS.

SilverMetal Enhanced — Windows (LTSC IoT installer + hardening + Stack) — Tier C
SilverMetal Enhanced — macOS (signed config profile + setup script + Stack) — Tier C-D
SilverMetal Enhanced — iOS (MDM profile + Stack) — Tier D
SilverMetal Enhanced — Android (generic profile + Stack on existing Android) — Tier D

Tiers explained in docs/platform-matrix.md.

What every SilverMetal device gets

Both lines ship the SilverLABS Application Stack — a suite of cross-platform privacy apps that replace the cloud services your device normally talks to (Google, Apple, Microsoft):

Component	Status	Purpose
SilverBrowser	v1 (Linux MVP)	De-Googled, telemetry-free, fingerprint-resistant browser
SilverVPN	Existing — see `SilverLABS/SilverVPN`	Always-on, no-logs VPN with our own infrastructure
SilverSync	v1 (Linux MVP)	Private replacement for iCloud / Google Drive / OneDrive
SilverChat	v1.1 (may overlap with `SilverVPN.Client.Chat`)	E2EE messenger
SilverDuress	v1.1	Duress password / panic-wipe / anti-coercion
SilverKeys	v1.1	Zero-knowledge password + 2FA manager

Two ways to get SilverMetal

Every flavour — OS or Enhanced — supports both buyer modes:

"I'm choosing a new device"

Buy a preflashed SilverMetal SKU. We've done all the work; it arrives ready.

"I already own a device and want to harden it"

Download the free SilverLABS Stack + the SilverMetal OS or Enhanced package for your platform. Apply it yourself. Same software, same hardening, no hardware lock-in.

Status

Component	Status
Documentation + roadmap	Initial scaffold complete
SilverMetal OS — Linux v1	Phase 1 — moving to milestone 1.1 (build pipeline)
SilverLABS Stack v1 (Browser + Sync)	Planning
SilverVPN	Existing product, integration into v1 ISO planned
Other OS/Enhanced flavours	Planning, post-Linux v1

See docs/roadmap.md for the milestone-driven plan.

Repo	Relationship
`SilverLABS/SilverVPN`	The VPN component of the SilverLABS Stack — already in production. SilverMetal integrates it; does not re-implement it
`SilverLABS/SilverApple`	Deprecated. Earlier iOS-hardening prototype, superseded by SilverMetal Enhanced — iOS
`SilverLABS/SilverDROID`	Unrelated (SilverSHELL AppStore Android client). Name is similar but scope is different
