"""The instance-identity env vars must actually bind (CUST-WP-0067-T03).
The chart sets STATE_HUB_INSTANCE_ROLE. pydantic-settings derives the env var
from the *field name*, so a field called `instance_role` silently ignores it and
the hub reports "unknown" while the ConfigMap says "primary" — config that is
declared but never reaches what it configures, which is the entire failure this
workplan exists to close.
