v1.7.122-alpha was the last release signed with the old root — it is the
release that installed the new pin on every node. From v1.7.123 the new
root signs, and a node running .122+ rejects an old-key signature. The
ARCHY_RELEASE_ROOT_PUBKEY override is no longer needed either: the signer
built from this tree pins the same key we now sign with.

The rotation commit pointed create-release.sh and publish-release-assets.sh
at the NEW root in the same commit that pins it in the binary. But the
release CARRYING the rotation must be signed with the OLD root: every node
is still running the previous binary, which pins the old key. So the
tooling would have rejected the only signature the fleet can accept, and
the signature it demanded would have ended OTA fleet-wide.
Both checks now expect the old DID for this cycle, with the flip to the new
one called out for v1.7.123+. sign-manifest.sh documents the
ARCHY_RELEASE_ROOT_PUBKEY override needed because the signer built from
this tree already pins the new anchor and would fail to verify its own
correct output.

check_for_updates now fetches the manifest as raw JSON and runs
trust::verify_detached before parsing: a tampered or wrong-signer
signature rejects the mirror outright, and unsigned manifests are
offered for MANUAL apply only — the 3 AM auto-apply scheduler refuses
them, closing the unattended remote-root hole (§A of the 1.8.0
hardening plan). UpdateState gains manifest_signed so the UI can
surface authenticity.
Publisher side: create-release.sh signs the manifest during the
release (ceremony, mnemonic via TTY/env only), publish-release-assets
hard-refuses to ship an unsigned manifest (grep + new 'ceremony
verify' cryptographic gate), and scripts/sign-manifest.sh covers
re-signing outside a release run.
