#
# Idempotent first-boot initialiser for the Mosaic Federation CA.
#
# On the first run (no /home/step/config/ca.json present) this script:
# 1. Initialises Step-CA with a JWK provisioner named "mosaic-fed".
# 2. Writes the CA configuration to the persistent volume at /home/step.
#
# On subsequent runs (config already exists) this script skips init and
# starts the CA directly.
#
# The provisioner name "mosaic-fed" is consumed by:
# apps/gateway/src/federation/ca.service.ts (added in M2-04)
#
# Password source:
# Dev: mounted from ./infra/step-ca/dev-password via bind mount.
# Prod: mounted from a Docker secret at /run/secrets/ca_password.
#
# OID template:
# infra/step-ca/templates/federation.tpl is copied into the CA config
# directory so the JWK provisioner can reference it. The template
# skeleton is wired in M2-04 when the CA service lands the SAN-bearing
# CSR work.
