June 2025 monthly summary for ynput/ayon-core: Consolidated loader hook system and refactored API into a single extensible hook class, introducing is_compatible checks and monkey-patched load behavior when hooks are present to simplify loading pipelines and improve extensibility. Performed broad typing enhancements across loader-related modules and introduced abstractmethod usage for API clarity. Implemented core API improvements and cleanup, including Python 3.7 typing compatibility and monkey patch refactoring. Added deterministic plugin processing order via an order attribute and refined sorting to ensure consistent plugin/results execution. Expanded lifecycle support by introducing pre/post hooks for update and remove operations, enabling custom processing around these events. Enhanced representations handling by extracting source_resolution_* fields and providing burn-in text templates. Documentation updates and inline comment improvements supported long-term maintainability. Key bug fixes include restoring correct loader/hook behavior (fix missing return path, remove unintended None assignments, fix wrong usage of Hook vs LoaderPlugin), and preventing overwrites of previously collected data. Cleanup work included formatting and renaming improvements to improve readability.
