Summary
This PR prepares the core library and validation layers for the upcoming A2UI v1.0 and Express compiler outputs. It introduces support for v1.0 schemas and enhances component reference resolution for nested slot structures.
This contains the v1.0 validation portions of #1678, with some additional issues fixed, additional tests, and refinements.
Changes
VERSION_1_0to the Python SDKA2uiValidator(controlled via theA2UI_VERSION_1_0orA2UI_EXPRESS_ENABLEDenvironment variables).catalog_schema_validator.pyandnode_graph.pyto supportRefFieldsTuplewith anested_refsmapping. This allows validation and graph resolution of component references nested inside list templates or object slots.integrity_checker.pyto recursively validate nested reference paths without raising false-positive dangling reference errors.Impact & Risks
None. These changes are fully backward-compatible. Legacy v0.8 and v0.9/v0.9.1 validations remain active and unchanged.
Testing
a2ui_coreanda2ui_agentpass cleanly.
