# ---- The provider "maas" CONFIG block is deliberately DEFERRED to Stage 3
# (DOCFIX-179, decided on the first real `tofu plan`). No module instantiated in
# Stage 1-2 uses the maas provider (modules/maas-vm-host is a Stage-3 module,
# commented out below), yet a configured provider "maas" block here forced
# `tofu plan` to demand maas_api_url AND the SENSITIVE maas_api_key for a plan
# that creates ZERO MAAS resources -- which would bake a fake key into
# plan/state (the DOCFIX-175 plaintext-secret surface). maas stays in
# versions.tf's required_providers (version pinned, lock-file complete); Stage 3
# re-adds this provider block + its two variables when it actually instantiates
# modules/maas-vm-host. modules/netem-link is likewise not instantiated yet
# (needs a real bridge/SSH target + netem params). See gap register items
# 2/4/11 and opentofu/README.md. ----
