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.

SUMMARY = "Firmware and extension verification public keys"

DESCRIPTION = "Trust anchors for archive verification: the ForgeFIRM \
|
|
release-signing public key (verifies release downloads and uploads), the \
|
|
Glowforge factory keyring (verifies factory .fw archives for cloud \
|
|
restore), and the OpenGlow extension-signing public key (the official \
|
|
tier of extension packages). Public keys only."
|
|
# LICENSE covers this recipe, not the key material. The Glowforge factory
|
|
# keyring in files/gf/ is Glowforge, Inc.'s: bare Ed25519 public keys, in which
|
|
# no copyright subsists and over which OpenGlow claims nothing and grants
|
|
# nothing. files/gf/README records that and the public-key-only boundary.
