# dry-run-nonroot-user.sh — safe, self-contained non-root user lifecycle dry-run (T06)
#
# Usage:
#   ./dry-run-nonroot-user.sh <username> <email> "<Display Name>" [options]
#
# Options:
#   --actor user|tenant-admin|fabric-admin   (default: user)
#   --scope "tenant:foo" or "none"
#   --no-lockoffboard                        (just onboard + verify)
#   --keep-user                              (do not delete at end)
#   --cleanup-only <username>
#
# It:
# - Uses only non-secret operations + k8s secret extraction into a temp /tmp workspace with trap cleanup.
# - Never leaves plaintext in the persistent sso-mfa/bootstrap/secrets tree.
# - Produces /tmp/netkingdom-onboarding-dry-run/evidence.json (populated from template + live data).
# - Exercises the full T05 flow + T06 verifications/lock/offboard.
# - Cleans up by default.
#
# Requires: kubectl (with access to sso ns), curl, python3, jq (optional but nice).
#
# This is T06-adjacent polish (NET-WP-0019-T01).
