Fail-closed pre-render capability checks and the Restage capability sidecar for apps rendering cached A2UI (Google genui) surfaces.

0.2.0 #

  • Accept constructor-derived custom properties and canonical a2ui.Config usage/write-back metadata.
  • Derive callback identity from the exact constructor property name; custom widgets no longer declare events through an RFW event list.
  • Migrate the A2UI integration to genui 0.10.1 and a2ui_core. The A2UI message model relocated into package:a2ui_core (CreateSurfaceMessage, UpdateComponentsMessage, …); the A2UI wire is unchanged (still v0.9).
  • genui 0.10.1 requires json_schema_builder 0.1.6 (a required transitive bump). 0.1.6 serializes the JSON-schema default additionalProperties: true explicitly on the runtime schema value — a runtime-only detail that does not reach the emitted catalog document. The bundled generated catalog and its content-derived catalogId are unchanged.
  • genui 0.10.1 performs full JSON-schema validation of components (a tightening over 0.9.2's enum-only checks). Validation is report-only and does not change the fail-closed pre-render check, which remains the authoritative gate.
  • Breaking generated payload layout: custom widgets and opaque native screens now keep protocol id/component on the envelope and nest every exact constructor input under one required props object. Regenerate the catalog and migrate producer/cached fixtures together. The runtime pre-render-check API and A2UI v0.9.1 protocol version are unchanged.
  • Expand the executable example with several arbitrary child-bearing input names on one component and real genui render coverage for the uniform props layout.
  • Update the bundled generated catalog and documentation for content-derived catalog identity, typed constraints, controlled values, nested data descriptions, and automatic custom-widget generation.

0.1.5 #

  • Document the producer-facing catalog metadata: widget and property descriptions, plus the new optional usage steering text, now emit into the generated catalog's system-prompt fragments, so a model reading the catalog on its own knows when to reach for each widget (see restage_codegen 1.2.0).
  • Expand the bundled example with a second catalog (callout, comparison panel, quiz check, section header) and add render-proof tests that build every component against the real SDK.
  • This package is unchanged at runtime.

0.1.4 #

  • Documentation: README refresh.

0.1.3 #

  • Update the catalog walkthrough to drop the removed build_runner --delete-conflicting-outputs flag.
  • Regenerate the bundled example catalog so its standalone A2UI document carries each component's full data schema (see restage_codegen 1.0.4). This package is unchanged at runtime.

0.1.2 #

  • Document the A2UI emit target's rich structured data support: a @RestageWidget property typed as a custom data class (nested data classes, lists of objects, String-keyed maps, named records) generates a rich genui schema that reconstructs and renders the value, with a fail-safe on a missing required value.
  • Document the opt-in build_runner builder workflow that produces the generated catalog and the capability stamp from @RestageWidget source.
  • This package is unchanged at runtime; the rich-data support is in the build-time toolchain (restage_codegen). Sealed-class unions and native (RFW) delivery of custom structured data are tracked future capabilities.

0.1.1 #

  • Add a usage example.

0.1.0 #

  • Initial release: the app-side A2UI pre-render capability check and the Restage capability sidecar for cached A2UI payloads.
