Struct PlannedChange 

pub struct PlannedChange {
    pub state: DynamicValue,
    pub requires_replace: Vec<String>,
}

── THE PROTOCOL DATA MODEL MOVED TO magma-provider-api ──────────── ProviderSchema, PlannedChange, Diag, Severity, ProviderError and is_retryable were defined here. They describe what a provider SAYS, not how it is reached, so they now live in the contract crate — which depends on magma-cty alone, so a native provider can implement the contract without dragging in tonic.

The edge had to point this way: magma-provider-api declares the Provider trait, and THIS crate implements it, so the types could not stay in the crate the trait crate would have had to depend on.

Re-exported unchanged, so every magma_plugin::provider::<T> path still resolves. Relocation, not redesign. The provider’s full response to PlanResourceChange: the normalized planned state PLUS the attribute paths the provider says force a destroy+create instead of an in-place update (“requires replace”).

Terraform core reads this exact signal — computed by the provider inside this SAME RPC — to decide Update vs Replace; it is not something the schema or config can determine on their own (a provider’s ForceNew decision can be dynamic, e.g. via CustomizeDiff). Prior to this type existing, ProviderConn::plan_resource_change returned only the bare planned DynamicValue, silently discarding requires_replace — the ONE authoritative signal a provider gives for immutable/ForceNew attributes — before it ever reached magma-apply’s business logic.

Fields

state: DynamicValue

requires_replace: Vec<String>

Provider-reported attribute paths requiring replace, rendered as dotted diagnostic strings ("instance_types", "tags.name", "rules[2].port"). Empty ⇒ the provider says an in-place update is sufficient. Diagnostic-only shape: callers only need to know whether this is non-empty to trigger destroy+create orchestration (see magma-apply::engine::apply_one); the strings make requires_replace legible in logs/errors without threading a full typed attribute-path AST through every consumer.
