Bring the just-released A2UI support and latest Microsoft Agent Framework
(Python) into the showcase, following the langgraph-python A2UI pattern.
- Bump agent-framework-ag-ui[a2ui]/openai/core to 1.2.0/1.14.0/1.15.0. 1.2.0
is A2UI's first release; the [a2ui] extra pulls ag-ui-a2ui-toolkit.
- Add the a2ui-recovery demo, mirroring langgraph-python's recovery demo:
backend-owned A2UI via the adapter's native enable_a2ui (injectA2UITool=false),
which runs the shared toolkit validate/retry recovery loop in-process. The
heal pill recovers a malformed first render into a valid surface; the exhaust
pill hits the attempt cap and surfaces the a2ui_recovery_exhausted fallback.
Reuses the declarative-gen-ui catalog. Adds the agent, route, page, chat,
suggestions, a D6 aimock fixture (framework-unique prompts), and an e2e spec.
- Enrich the MAF A2UI docs page with how-to content covering the three A2UI
flavors (dynamic, fixed, recovery) and connect the three A2UI demos through
docs-links.
Validation: validate-pins clean (count/hash unchanged), validate-parity PASS,
generate-registry clean. The recovery loop is verified at the AG-UI protocol
layer against aimock on the published 1.2.0 wheel (heal streams a2ui_operations
after an invalid-then-valid render; exhaust returns a2ui_recovery_exhausted
after 3 attempts; RUN_FINISHED, no RUN_ERROR).
- Remove multimodal from features (already in not_supported_features);
the duplicate made generate-registry reject the manifest, blocking D6
from starting.
- Pin agent-framework-{ag-ui,openai,core} to exact published latest
(1.0.1 / 1.12.0 / 1.13.0) so validate-pins classifies them as exact
framework deps; drop unused langchain-openai/langchain-core.
- Ratchet validate-pins baseline down 31 -> 27 (the 4 non-exact framework
fails are now exact); ms-agent-python's only remaining FAIL is the
shared-frontend openai ^5.9.0, identical to every other integration.
The showcase framework directories better reflect their role as
integration examples rather than distributable packages.
Renames showcase/packages/ -> showcase/integrations/ and updates
the test docker-compose file reference accordingly.
