# agentmemory first-boot entrypoint.
#
# Runs as root so it can:
#   1. Overwrite the npm-bundled iii-config.yaml (which binds 127.0.0.1
#      and uses relative ./data paths) with a deploy-tuned version that
#      binds 0.0.0.0 and uses absolute /data paths.
#   2. chown the platform-mounted /data volume to the runtime user
#      (managed platforms mount volumes root-owned 755 by default).
#   3. Generate the HMAC secret on first boot and persist it to
#      /data/.hmac (chmod 600) so the secret survives restarts.
#
# Then it execs the agentmemory CLI under gosu as the unprivileged
# `node` user.
