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).
