Search Flights and Sales Dashboard pills both produce visible surfaces
on the langgraph-python beautiful-chat demo. Three independent bugs were
masking each other:
- Flight TypedDict required `id` + `statusIcon`, which the aimock fixture
doesn't supply. langchain rejected the call with `flights.0.id: Field
required` and the agent surfaced the error string as the tool result.
Made the type permissive (only the fields `_build_flight_components`
reads need to be there).
- search_flights now expands flights into literal-children FlightCard
components server-side instead of relying on the structural-children
template form (the binder doesn't reliably expand it for our custom
catalog — sibling demos avoid the form for the same reason).
- Sales Dashboard pill went into a tool-call loop because the
userMessage+toolName fixtures matched both the initial call and the
post-tool turn. Hoisted the toolCallId fixture above them so the
follow-up turn returns content and breaks the loop.
Custom Row/Column reintroduced with `gap` support — the basic catalog's
versions ignore it, leaving cards squished. Children are array-of-strings
only (matches what the agent and fixture emit).
Two new e2e tests cover both pills end-to-end. 3s wait in beforeEach so
the v2 chat provider hydrates before the click dispatches. Full spec:
7/7 green.
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.
