# `Backplane.JsonSchema.Types.ValidationContext`

Lightweight runtime context threaded through validation.

Holds a reference to the immutable root `Schema` and carries per-scope
state (scope stack, current source ID, raw schema, and resource-local pointer
cache) that changes as validation descends through `$id` boundaries.

# `t`

```elixir
@type t() :: %Backplane.JsonSchema.Types.ValidationContext{
  local_refs: map(),
  raw: map() | nil,
  root_schema: Backplane.JsonSchema.Types.Schema.t(),
  scope_stack: [String.t()],
  source_id: String.t() | nil
}
```
