Run #4268's build-and-verify died <1s into Build A: docker: Error response from daemon: No such container: docker Cause: build.sh's CI path uses `--volumes-from "$(hostname)"` to inherit the parent job container's /workspace mount, but in the new runner config (network: host applied via the now-actually-loaded config.yaml) `hostname` returns the literal string "docker" inside catthehacker/ubuntu:act-latest — the image bakes that into /etc/hostname and act_runner doesn't override it. So `--volumes-from docker` looks for a container literally named "docker", finds nothing, exits. This worked in earlier runs (#4260) only because config.yaml *wasn't being loaded* (see iter18 commit), so the runner ran on its built-in defaults — which kept the container's hostname as the auto-generated container ID. Fixing config.yaml exposed this latent bug. Right way to learn your own container ID inside a Linux container is /proc/self/cgroup, which contains the 64-char hex ID on every cgroup driver: cgroup v1: 12:devices:/docker/<64-hex> cgroup v2: 0::/system.slice/docker-<64-hex>.scope awk extracts the first 64-hex run; that becomes the --volumes-from argument. If extraction fails (would only happen on a non-docker runtime), fail loud rather than silent. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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 | Existing — SilverVPN.Client.Chat, Signal Protocol over VPN transport. Promoted from v1.1 to v1 |
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.

| SilverLABS Stack v1 (Browser + Sync) | Planning |
| SilverVPN | Existing product, integration into v1 ISO planned |
| SilverChat | Existing product (SilverVPN.Client.Chat); promoted to v1, integration into v1 ISO planned |
| Other OS/Enhanced flavours | Planning, post-Linux v1 |
