Run #4252 died at:
runuser: failed to execute /workspace/SilverLABS/SilverMetal/linux/build/scripts/build-inner.sh:
Permission denied
The script was created on the WSL/Windows side (/mnt/c) where every
file appears world-rwx regardless of git's index, so the local
`chmod +x` was a no-op as far as git was concerned and the file got
committed at mode 100644 like any other regular file. Sibling scripts
(build.sh, verify-reproducibility.sh, diagnose-divergence.sh) all
correctly carry 100755 in the index.
Fix: `git update-index --chmod=+x` to set the bit in the index
explicitly, independent of the working-tree perms.

Run #4251 advanced past checkout and into derivative-maker, then died
immediately:
ERROR: This must NOT be run as root (sudo)!
ERROR: Exiting ./derivative-maker with non-zero exit code 1.
Errors Detected: 0. Execution Time: 00:00:00.
Kicksecure's derivative-maker explicitly refuses to run as root — it
expects a regular user with passwordless sudo and uses sudo internally
for the privileged operations (debootstrap, mksquashfs, chroot mounts).
Our minimal debian-slim builder image had a `builder` user (uid 1000)
but no sudo, no sudoers entry, and the container ran as root.
Aligns with the upstream Kicksecure container pattern at
linux/build/derivative-maker/docker/derivative-maker-docker-setup
(uses USER=user with `${USER} ALL=(ALL) NOPASSWD:ALL`).
Changes:
- Dockerfile.builder: install `sudo` (and `fakeroot` while we're here —
upstream sanity-tests pulls this in via apt at build time, but having
it baked avoids a snapshot.debian.org round-trip every run); add
passwordless sudoers entry for builder; correct the misleading
comment that claimed root was needed.
- New scripts/build-inner.sh: the inner derivative-maker invocation
pulled out of build.sh's heredoc. Once we needed to drop privileges
via runuser, the nested-heredoc / nested-quoting situation became
unmaintainable; a regular script with normal quoting is far cleaner.
- build.sh: inner heredoc now just chowns the workspace to builder and
runuser's into build-inner.sh. ${REPO_ROOT} and ${BUILD_DIR} continue
to be forwarded into the container via -e.
- build.sh: BUILDER_IMAGE digest re-pinned to sha256:f8f0db37…1bedc
(rebuilt and pushed natively on 10.0.0.51 — never on the WSL/aarch64
dev box, see reference_silvermetal_runner.md memory).
Verified: bash -n on both scripts; image builds and pushes cleanly.
Pushing this commit triggers a fresh CI run that will exercise it.

build.sh ran fine locally but failed in Gitea Actions on the first
reproducibility-gated run (#4250) with:
bash: line 3: /work/linux/build/config/silvermetal-base.conf:
No such file or directory
Root cause: classic Docker-out-of-Docker confusion. build.sh runs
inside the act_runner job container, which talks to the host's docker
daemon via the mounted /var/run/docker.sock. The "-v ${REPO_ROOT}:/work"
flag was being interpreted by the host daemon against the host
filesystem, where /workspace/SilverLABS/SilverMetal does not exist;
docker silently auto-created an empty dir there and mounted that as
/work, so the config source target was missing.
Fix: detect GITHUB_ACTIONS and use --volumes-from "$(hostname)" in CI
to inherit the parent job container's /workspace mount intact. Locally
we keep a bind mount, but use the same path inside and outside
(${REPO_ROOT}:${REPO_ROOT}) so the inner heredoc is identical in both
modes. Inner script now references "${REPO_ROOT}/..." and
"${BUILD_DIR}/..." instead of the synthetic /work and /out paths.
No reproducibility implications — bind topology doesn't affect bytes
inside the ISO.
Verified locally: bash -n passes; structural change only, behaviour
preserved for the non-CI path.

Two corrections to f9e606d:
1. Registry hostname: docker-registry:5000 isn't DNS-resolvable on the
SLAB docker host (verified). The fleet-wide convention is the canonical
docker-registry.silverlabs.uk URL, registered as an insecure-registry
in /etc/docker/daemon.json on every docker host.
2. Architecture: the original push from WSL2-on-aarch64 produced an arm64
image that won't run on the amd64 runner. Rebuilt natively on the docker
host. New manifest digest (amd64-only):
sha256:9e7161f9f180483f434074d7f32c27c907955232bd0c44efe6dc0ee1d9e56ae0

act_runner-based deployment that handles `runs-on: silvermetal-builder` jobs.
Adapted from the stinky-roger-tv flutter-builder pattern with three changes:
- privileged: true (live-build needs loop devices + chroot)
- 4h job timeout (covers two reproducibility-gated ISO builds + diffoscope)
- silvermetal-builder label maps to catthehacker/ubuntu:act-latest, not the
silvermetal-builder image — the builder image stays minimal (no docker-cli),
and build.sh invokes it via `docker run` from the catthehacker job shell
Deployed at /opt/silvermetal-builder-runner/ on the SLAB docker host
(10.0.0.51); registered with git.silverlabs.uk and reporting healthy.

Image built from Dockerfile.builder@36f7672 was pushed to both
docker-registry:5000 (internal) and docker-registry.silverlabs.uk
(external) under tags m1.1-bootstrap + latest. Both URLs serve the
same registry, so the manifest digest is identical:
sha256:cedef039425e0b0f5901c1023eda820c7aa38ab4b81c2bb1e12d64cadb3d6c85
Default points at the internal hostname for CI; external dev overrides
via BUILDER_IMAGE env var.

- Pin debian:bookworm-slim by real digest (resolved 2026-04-26).
- Two-phase install: seed ca-certificates from the default mirror first
so HTTPS to snapshot.debian.org works, then swap to the pinned snapshot
for the toolchain itself. Slim images don't ship the CA bundle, so the
one-shot pinned-source-only install would deadlock on cert verification.
Validated locally: image builds clean, 302MB, all live-build / debootstrap /
mksquashfs / xorriso / diffoscope-minimal present.

Vendors Kicksecure derivative-maker as a pinned submodule (18.1.7.4),
adds the wrapper + verify + diagnose scripts, the pinned builder image,
and the reproducibility-gated Gitea Actions workflow. Base flavour only —
no hardening overlay (that's M1.2).

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.
