The nostr bridge derived the caller from the launcher's own URL and
never checked event.origin, so any co-resident iframe could pull the
node's nostr pubkey or use nip04/nip44 decrypt as an oracle while an
app was open. The bridge now rejects senders whose real origin doesn't
match the open app's origin, and every identity-sensitive method
(getPublicKey, signEvent, encrypt/decrypt) requires user consent or a
remembered per-origin approval — previously only signEvent did.
share-to-mesh in App.vue likewise accepted messages from any sender
and force-navigated to /mesh with an attacker-staged CID; it now
requires same-origin, matching Chat.vue's existing handler.

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.

Pin RELEASE_ROOT_PUBKEY_HEX from the 2026-07-02 release-root signing ceremony
(signer did🔑z6MkkidEnEpo6qHMCNSZoNKWtvQvxq3whnaME9wGgEFhq7ur) so nodes verify
the publisher identity of the app-catalog. Sign releases/app-catalog.json in place.
Fix two floats that made the catalog unsignable: archy-btcpay-db manifest version
-> string, fedimint-clientd cpu_limit 0.25 -> 1 (u32). Add scripts/sign-catalog.sh
helper, the 1.8.0 release-hardening plan/tracker, and the commit-and-push project
rule in CLAUDE.md.
Backward-compatible: old binaries still accept the signed catalog; the pinned-anchor
binary ships in the next build/OTA.
