cat <<'USAGE'
Usage: scripts/openbao-apply-initial-config.sh [--dry-run]
Applies the first post-unseal OpenBao configuration:
- file audit device
- platform KV v2 mount
- Kubernetes auth mount and in-cluster config
- platform-admin and platform-readonly policies
This script must run only after the bootstrap ceremony initializes and unseals
OpenBao. It reads the bootstrap/root or platform-admin token from:
1. OPENBAO_TOKEN_FILE, when set
2. an interactive hidden prompt
It does not print the token and does not store it.

cat <<'NEXT'
Initial OpenBao configuration applied.
Next manual steps:
1. Create a non-root platform-admin token with a short TTL or renewable period.
2. Store that token through the approved human/operator secret path.
3. Revoke or tightly escrow the initial root token.
4. Run the raft snapshot and restore drill before moving live secrets.
