Research gap analysis of ex_a2ui (v0.8) vs A2UI spec (v0.9). Roadmap updated with migration plan through v0.6.0. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Migrate encoder/decoder to A2UI spec v0.9 wire format. This is a breaking change to the JSON output and decoder return types. Wire format: messages renamed (updateComponents, updateDataModel, createSurface, action), all messages versioned and array-wrapped, component properties at top level, literal values plain (no wrapper), action uses event envelope with metadata. Types: added :audio_player, renamed :multiple_choice → :choice_picker (18 standard types). Surface gained catalog_id field. 100 tests. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
