# One-step OTA-manifest signer (counterpart to sign-catalog.sh).

# Signs releases/manifest.json in place and cryptographically verifies the
# result against the pinned release-root anchor. The mnemonic is read from the
# terminal only (never stored, never in shell history, never passed to Claude).
#
# Normally create-release.sh signs the manifest inline; this script exists for
# re-signing (e.g. a manifest edited after creation) or signing on a box where
# the release run was non-interactive.
#
# ⚠ ROTATION IN FLIGHT (v1.7.122-alpha). This release must be signed with the
# OLD release root, because every node still runs a binary pinning it — but
# the signer built from THIS tree already pins the NEW root, so its own
# verification would reject a correct old-key signature. Pin the old anchor
# for the duration of the ceremony so signing and verification agree:
#
#   ARCHY_RELEASE_ROOT_PUBKEY=5d15cbee8a108f7dd288c02d29a1d9d71f198acc99186aad8008b4f28d469951 \
#     bash scripts/sign-manifest.sh
#
# That hex is the OLD root's PUBLIC key (verified to derive to
# did:key:z6Mkkid…q7ur); it is not secret and pins verification only.
# From v1.7.123 the override is unnecessary — drop it and this block.
