    "CRITICAL — an import is not complete until the plan afterwards is a genuine no-op. A plan that still proposes changes after import means the configuration does not describe the real object, and applying it will modify or replace production infrastructure that was working a moment earlier; treat any non-empty post-import plan as a block, not as a cleanup task.",
    "CRITICAL — never resolve an address change with `state mv` when a `moved` block expresses it. A `moved` block is reviewed, versioned, and travels with the code to every workspace and every collaborator; `state mv` is a one-off action against one state that leaves no record anywhere and must be repeated correctly by every operator in every environment.",
    "CRITICAL — removing a resource block destroys the infrastructure, while a `removed` block releases it from management and leaves it running. Never describe these as alternatives without naming which outcome the user wants, because the wrong one is unrecoverable in one direction and produces an unmanaged orphan in the other.",
    "HIGH — classify drift before proposing a disposition. Unauthorized change, authorized out-of-band fix, externally owned attribute, and provider-side representation artifact each demand a different response, and treating all drift as something to revert is how an emergency fix made during an incident gets silently rolled back on the next apply.",
    "HIGH — observe drift with a `-refresh-only` plan rather than a normal plan. A normal plan mixes drift with configuration changes and invites resolving both in one apply, which makes it impossible to tell afterwards which change came from the repository and which from reality.",
    "HIGH — `ignore_changes` is an ownership statement, not a fix. Accepting drift through it is legitimate only when the attribute is genuinely owned by another system and that owner is named; an `ignore_changes` added to stop a recurring diff without a named owner converts a visible disagreement into an invisible one.",
    "HIGH — `identity` and `id` are not interchangeable in an import block: `identity` addresses a remote object by a set of attributes and is the modern form, while `id` takes a single provider-assigned string, and which one applies is a property of the resource type. Require the provider's own documentation for the resource type rather than inferring the format from a similar resource.",
    "MEDIUM — generated configuration is a starting point, not an artifact to commit as-is: it reproduces the object's current attributes without the module structure, variables, naming, or policy defaults the estate uses, and it is marked experimental on OpenTofu, where it cannot currently be combined with `for_each` on import blocks.",
    "MEDIUM — sequence a large adoption so each step is independently verifiable: import the resources with no dependents first, confirm a no-op plan, then proceed. A single bulk import whose plan is not a no-op cannot be reasoned about, because there is no way to tell which resource caused the diff.",
    "MEDIUM — an import writes to state, so it requires the same preconditions as any other state mutation: a restorable copy first, and a lock held for the duration. Hand the recovery posture question to `terraform-state-reliability-agent` rather than assuming it.",
    "MEDIUM — measure unresolved drift by age, not by count. A count falls when someone reverts everything indiscriminately and rises when detection improves, while the age of the oldest unreconciled difference tracks whether anyone is actually deciding.",
    "LOW — a resource that repeatedly drifts in the same attribute is a design finding rather than an operations finding: something else owns that attribute, and the durable fix is to model that ownership rather than to reconcile it again."
