    "incantation": "When a managed resource’s destroy protection should follow a module value, set `lifecycle.prevent_destroy` to a same-module expression such as `var.prevent_destroy_database` (available in OpenTofu v1.12.0).",
    "examples": [
      "variable \"prevent_destroy_database\" {\n  type    = bool\n  default = true\n}\n\nresource \"example_database\" \"example\" {\n  # ...\n  lifecycle {\n    prevent_destroy = var.prevent_destroy_database\n  }\n}"
    ],
    "gotchas": [
      "Version: v1.12.0",
      "lifecycle.prevent_destroy: Boolean lifecycle argument; when true, OpenTofu errors on plans that destroy the associated object. In v1.12.0 it can be set dynamically from same-module values.",
      "prevent_destroy_database: Example input variable of type `bool`; its default is true, making it optional to callers. Child-module callers pass its value in the module block.",
      "Prerequisite: Use OpenTofu v1.12.0 or later for dynamically defined `prevent_destroy`.",
      "Prerequisite: Declare any referenced input variable in the same module; the example uses `type = bool`.",
      "The referenced values must be available elsewhere in the same module."
