# `Backplane.JsonSchema.Validator.Reference`

Resolves `$ref` and `$dynamicRef` during validation, including remote schema
loading and JIT compilation of JSON Pointer references. Prepares resource-local
validation contexts for structural descent and resolved reference targets.

# `validate_dynamic_ref`

Resolves a `$dynamicRef` by checking if the static target has a matching
`$dynamicAnchor`, then performing dynamic scope lookup through the scope stack.
Falls back to static `$ref` resolution if no dynamic anchor is found.

# `validate_ref`

Resolves and validates a static `$ref`.

Looks up the target schema in the compiled `defs` registry. If not found locally
and the reference points to a remote URI, attempts to load it using the `loader`.
Supports JSON Pointer references, anchor references, and absolute/relative URIs.

# `validate_ref`

Validates a compiled `$ref` using its pre-resolved lookup key.

`ref_string` is the original reference; `resolved_uri` is the binary key computed
during compilation and is looked up without resolving it again. Fragment-only
keys distinguish resource-local pointer aliases from registered anchors; other
keys are looked up directly in the shared `defs` registry. Cache hits prepare
the target's resource context before validation.

On a cache miss, falls back to `validate_ref/3` with the original reference,
allowing built-in schema loading, remote loading, and JIT JSON Pointer resolution.
