#!/usr/bin/env bash
#
# Build EVERY image this household needs, from one CoreSystemConfig.json.
#
# This is the normal way to use tools/. The individual builders still exist and still
# work, but rebuilding one image on its own is the unusual case: the images are a set
# that has to agree with itself, and the whole reason a kiosk knows the container
# host's address is that both were generated in the same pass from the same file.
# Building the set is therefore the default, and building one is the exception.
#
#   sudo -E tools/build-all.sh              # the core pair + every configured kiosk
#   sudo -E tools/build-all.sh --core       # just the twinned pair
#   sudo -E tools/build-all.sh --kiosks     # just the kiosks
#   sudo -E tools/build-all.sh --dry-run    # validate + list what would be built
#
# Every image is stamped with the same pair ID, so a drawer full of USB sticks can be
# checked against each other later: same ID means they were built from the same
# config and agree on every address and token.
#
# WHAT COMES OUT CONTAINS SECRETS. Wi-Fi PSK, service tokens, MQTT and HA credentials
# are burnt into these images — that is the point (nothing to configure post-install),
# and it makes every ISO a credential. .gitignore keeps them out of the repo; wiping
# old USB sticks is on you.

  Install the container host FIRST — the kiosks and the LLM host are all
  clients of it, and every one of them was built expecting it at
  ${CORE_CONTAINER_HOST_IP}.

  Two things still need a human, because neither exists at build time:
    1. HA_TOKEN  — a Long-Lived Access Token from Home Assistant's own UI, which
       can't be created until HA is running. Put it in CoreSystemConfig.json and
       rebuild, or edit identity.env on the container host.
    2. TRUSTED_ENTITY_PREFIXES — the real entity_id prefixes your Private BLE
       Device setup produces. The default is a guess and it is the highest-risk
       unknown in Phase 6.
