chore: fully remove and strip A2UI experimental feature 3 months ago
Authored
mweinbach 6/30/2026, 4:12:07 AM - Delete src/experimental/a2ui/, test/a2ui/, skills/a2ui/, desktop/mobile A2UI UI and test files
- Remove a2ui from types, config, prompt, tools, session, projection, runtime, desktop store/actions/UI, mobile
- Clean incidental references, mocks, and A2UI-specific tests across the suite
- Update docs (websocket-protocol.md, architecture.md) and biome config
- All references removed (rg zero outside CHANGELOG); checks (lint, typecheck, docs:check) pass
