# HCP plan/apply roles imported from seahaven-terraform-substrate (PLAT-146).
# Import, do not recreate. Role names stay hcptf-seahaven-door-unlock-api / hcptf-seahaven-door-unlock-api-plan.
#
# Live seahaven-hcptf-iam-management DenySelfMutation blocks DetachRolePolicy
# and PutRolePolicy on hcptf-* (including this role). Import apply sequence:
#   1. seahaven-org-baseline scripts/create-hcptf-bootstrap-roles.sh
#        --account prod --allow-workspace seahaven-door-unlock-api-prod
#   2. Point this workspace's TFC_AWS_* at hcptf-bootstrap /
#      hcptf-bootstrap-plan (workspace vars, never a project set).
#   3. One Manual apply (import + detach seahaven-hcptf-iam-management +
#      put scoped inline).
#   4. Point TFC_AWS_* back at hcptf-seahaven-door-unlock-api / hcptf-seahaven-door-unlock-api-plan.
#   5. Re-run the script without --allow-workspace to pin trust back to
#      iam-bootstrap-prod only.
# seahaven-lambda-execution-boundary remains seahaven-lambda-execution-boundary-seahaven-door-unlock-api.
