Reference Metadata Preservation and Reference Key Lookup

Changed

• Added resolve_ref_key(property_name) on metadata-backed Rune objects to return the stored reference key for a reference property, or None when the property is not backed by a reference.
• Renamed the new helper from resolve_ref to resolve_ref_key for clearer API intent.

Fixed

• Fixed reference metadata loss during BaseDataClass re-validation. When re-validation creates a fresh object and clears previously established reference metadata, the runtime now restores the original refs container when appropriate.

Tests

• Added coverage for resolving stored reference keys in test_keys_and_references.py (line 278).
• Verified with: ..pydevenv\Scripts\python.exe -m pytest test/test_keys_and_references.py
• Result: 39 passed

Included Commits

• 7c74c20 Add utility function to return the reference of a property if the property is a reference.
• 92c8cbb renamed to more accurate name
• e5c16cd Fix metadata handling in BaseDataClass during re-validation

Rune Functions Support

Rune Python Runtime 2.0.0

Rune Python Runtime 2.0.0 is a major update focused on function execution support, safer mutation semantics, and better compatibility with generated Rune model packages.

Highlights

• Added first-class runtime support for generated Rune functions.
• Introduced replaceable function proxies, scoped function replacement, unchecked invocation helpers, and native function registration/loading.
• Added copy-on-write support for models, builders, lists, dicts, and sets so generated functions can work with mutable views without mutating original inputs.
• Introduced ObjectBuilder for draft-style model construction and materialization into validated Rune models.
• Improved BaseDataClass, metadata, and reference handling to better support Pydantic validation, function return finalization, and internal, external, and scoped references.
• Added support for namespace-prefixed model installations, allowing prefixed generated packages and native implementations to be resolved correctly.
• Aligned utility behavior more closely with Rune semantics for null handling, list operations, attribute resolution, and cardinality checks.
• Expanded test coverage across function execution, copy-on-write behavior, object building, key/reference resolution, namespace-prefix handling, and runtime utilities.

Breaking Changes

• Some older mutation-oriented helper patterns have been replaced by ObjectBuilder, copy-on-write wrappers, and rune_add_to_list.
• Edge-case behavior involving None, empty collections, and list comparisons now follows Rune semantics more closely and may differ from 1.x releases.

Upgrade Notes

• Update any custom code that relied on Draft to use ObjectBuilder.
• Review custom integrations around runtime helper utilities if they depended on legacy mutation helpers.
• If you use generated Rune functions or prefixed generated packages, upgrade the runtime together with a compatible generator output.

This release lays the foundation for richer generated-function support in Python while improving model safety, interoperability, and correctness.
