- Daily account defaults to Standard User (least-privilege) + separate SilverOS
Admin elevation account; single-admin model demoted to an option.
- Hardened baseline applies to ALL flavours (none unhardened); Daily-Driver is the
default/recommended (balanced middle), Privacy-Max is opt-in strictest.
- Name confirmed: SilverOS Welcome. Stack installs remain gated.

- Local admin password -> "open sesame" (still a placeholder for the public repo;
SKU pipeline must replace per-device).
- UK keyboard (InputLocale 0809) + UK region/formats (SystemLocale/UserLocale
en-GB). Display UILanguage stays en-US because the eval media is en-US and lacks
the en-GB display pack -- true en-GB display needs en-GB LTSC media or an injected
language pack (future build step).

VM run: `powercfg /hibernate on` writes to stderr where hibernation is unsupported
(VMs), which under ErrorActionPreference=Stop aborted module G after its earlier
lock-screen settings applied. Wrap it so the module completes cleanly.

VM runtime test (offline disk mount) revealed SetupComplete.cmd ran but its inline
multi-line `powershell -Command` (cmd ^-continuation + nested escaped quotes) failed
to parse ("string is missing the terminator") -> the §A-H modules never executed.
Offline CI assertions only proved the files were BAKED, not that they RUN.
Fix: move the module runner into hardening/Invoke-Hardening.ps1 and call it with
-File (no cmd quoting). Runner runs 00*..08* in order then Verify (writes
verify-report.json in-line as SYSTEM; reboot/PIN-dependent gates show pending).

VM run reached OOBE but the region/keyboard pages were still interactive: the
oobeSystem pass lacked Microsoft-Windows-International-Core, so 24H2 OOBE
(CloudExperienceHost) prompted for them even under legacy Setup. Add it +
HideOEMRegistrationScreen + HideLocalAccountScreen so OOBE is fully hands-off to
the local account / desktop.

The no-prompt efisys + media-first boot order reboot-loops: every post-copy reboot
re-boots the media before the disk install completes, so it never finishes (symptom:
"no bootable device" after ejecting). Standard efisys.bin (press-any-key) lets reboots
fall through to the installed disk. Legacy-Setup boot.wim patch + /unattend retained
(the real fix). Documented VM-verified result + the residual one-click WinPE language
page in iso-builder.md.

Legacy Setup (forced via boot.wim CmdLine) still showed the language page because
implicit answer-file search is unreliable when setup is launched via CmdLine. Inject
autounattend.xml into boot.wim (X:\autounattend.xml) and set CmdLine to
"X:\sources\setup.exe /unattend:X:\autounattend.xml" so all passes are consumed.

VM test proved Win11 24H2 redesigned "ConX" Setup ignores the windowsPE pass of
autounattend.xml (manual language/keyboard/region prompts). Deep-research-verified
fix: patch sources\boot.wim index 2 to launch the legacy installer.
build.ps1 stage 2b: mount boot.wim idx2, load offline SYSTEM hive, set
HKLM\SYSTEM\Setup\CmdLine=X:\sources\setup.exe, unload, commit. Also place
autounattend.xml in \sources as well as ISO root. Legacy engine consumes all
four passes -> fully hands-off. Documented in iso-builder.md §3a (incl. rejected
winpeshl.ini / RunSynchronous alternatives + ConX-may-change caveat).

VM boot test proved the ISO boots under UEFI+SecureBoot+TPM2 but stopped at the
"press any key" prompt and (post-boot) the disk screen. Enable hands-off install:
- build.ps1: use efisys_noprompt.bin (fall back to efisys.bin) so the ISO boots
without a keypress.
- autounattend.xml: add GPT/UEFI DiskConfiguration (wipe disk 0 -> EFI/MSR/Win),
ImageInstall index 1, AcceptEula (eval = no key). Bootstrap local-admin pw is a
PLACEHOLDER the SKU pipeline must replace.

Stages 1-5 pass; oscdimg failed with Error 123 because PowerShell doubled the
embedded quotes in -bootdata. Work paths have no spaces, so omit the inner
quotes around etfsboot.com/efisys.bin entirely.

Base eval ISO staged at C:\silvermetal\base.iso on GITEA-RUN-WIN (SHA256
2CEE70BD...CB29 pinned in inputs.manifest.json). Repo var now points at that
local path, so the build reads locally - no NAS share auth / no CI creds.
Dropped -SkipInputVerify so the build verifies the pinned hash.

Implement build.ps1 (M2): mount/extract the base ISO, offline-service
install.wim (inject GPD drivers if staged, debloat appx, bake SetupComplete.cmd
+ hardening modules into \Windows\Setup\Scripts), inject autounattend.xml,
oscdimg UEFI repack, emit SHA-256 + SBOM. Elevation + oscdimg guarded.
Add .gitea/workflows/build-iso-windows.yaml: runs on the self-hosted
silverlabs-runner-win (windows-latest), ensures ADK Deployment Tools, acquires
the base ISO from repo var SILVERMETAL_BASE_ISO_URL or a pre-staged path, builds,
validates the baked payload offline, uploads SBOM/SHA (+ISO on dispatch/tag),
attaches to a Gitea release on win-v* tags. Mirrors build-iso-linux.yaml.
Add tests/Assert-IsoStructure.ps1: the no-nested-virt CI gate - mounts the built
ISO + install.wim read-only and asserts autounattend.xml, SetupComplete.cmd, and
the hardening modules are correctly baked. Full QEMU boot+Verify is a follow-on.
Switch autounattend to Windows' native SetupComplete.cmd auto-run (SYSTEM, end
of setup) instead of a duplicate FirstLogonCommands call.
Untested until first runner execution (dev box is ARM64). All PS parse-clean;
autounattend XML + workflow YAML valid.

Add windows/hardening-spec.md: the detailed config-layer hardening spec for
SilverMetal Enhanced - Windows, with the GPD Pocket 4 (AMD Strix Point) as
reference device. Eight control domains (provisioning, boot/firmware trust,
data-at-rest, kernel/credential isolation, app control, network/radios,
physical/lock-screen, privacy/update) each with verification commands, a
buyer-facing residual-risk statement, and one-off -> SKU productization notes.
Refine the windows/README.md v1 scope to match, grounded in the 2026-06-08
deep-research assessment:
- BitLocker TPM+PIN (never TPM-only) - PIN defeats the faulTPM-class offline
fTPM attack that is literally a BitLocker VMK extraction
- WDAC (App Control), kernel-enforced, audit-first then enforce, as primary;
AppLocker demoted to fallback (rename planned applocker/ -> wdac/)
- Telemetry at GP+service+firewall layers, NOT hosts-file blocking of MS
domains (that breaks Windows Update; violates "update or die")
- Add VBS/HVCI/Credential Guard/Kernel DMA Protection to scope + verify gates
- Note Enterprise (prototype) vs IoT Enterprise LTSC (SKU target) equivalence
Bound by docs/threat-model.md and docs/design-principles.md; nation-state /
firmware tier explicitly NOT claimed on consumer UMPC silicon.

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.
