forgeext is the extension host, a component of its own: recipe
recipes-forgefirm/forgeext (cmake, pkgconfig, forgefirm-manifest, so it is
a manifest component with its own pin file). It links jansson, libarchive,
and libsodium, and runs with fwup, the keyring, and forgefirm-sandbox.
libarchive and jansson are on the image already; libsodium comes with it.
The pin is all zeros because the repository has no pushed commit to name:
the recipe builds from a working tree through externalsrc, and a build
from pins cannot fetch it until the first push sets the pin. It is not in
the image's install list.
forgefirm-keys installs a third trust anchor,
/etc/forgefirm/keys/ext/forgefirm-ext.pub: the OpenGlow extension-signing
public key, the official tier of extension packages. It is a different key
from the release key on purpose: it signs more often, and its loss must
not sign firmware. forgeext refuses an extension archive whose only valid
signature is the release key's or a factory key's.
Proven. The recipe cross-builds forgeext from the working tree, and that
binary ran the verify-and-install cases on the bench reference (image
20260920211625, from /tmp, with the board's own fwup 1.16.0 and the
image's keyring) with the results of the host test. forgefirm-keys builds
and packages the key 0644 under ext/ (0755), byte-identical to the file
here; it is 32 key bytes and is not the release key.
Acceptance. No catalog test reads either yet: forgeext's tests are the
exthost suite that comes with its daemon, and the key is layer content, in
the platform identity of every fingerprint.
/etc/forgefirm/keys ships the ForgeFIRM release-signing public key
and the Glowforge factory keyring (public keys only) - the update
manager verifies release downloads/uploads against the former and
factory archives against the latter. forgectrl SRCREV bumped to the
update-manager commit; runtime deps on ffboot, fwup, the keyring, and
curl made explicit.
