Fixes defects 3, 4, 6, 7, 8, 10, 11 and 12 from the OSS-856 phase 1
validation run. Every claim below was re-verified against installed
package source or a live run, not recalled.
LangGraph quickstart (`integrations/langgraph/quickstart.mdx`):
- Route shape: a caution at the route step. The POST-only route runs the
runtime in single-route mode, which is all chat needs; Threads and the
Inspector need the multi-route catch-all with GET/POST/PATCH/DELETE.
Links to the canonical runtime-endpoints section.
- Port: bare `langgraph dev` serves 2024, not 8123. Verified against both
CLIs (`@langchain/langgraph-cli` help output, and `default=2024` in
`langgraph_cli/cli.py`). The guide keeps `--port 8123` to stay
consistent with every sibling page, and now says so.
- Drop `@copilotkit/react-ui` from the install list. `CopilotSidebar`
lives in `@copilotkit/react-core/v2`; react-ui exports no `./v2` JS
entry point and the v2 react example does not depend on it.
- Checkpointer: state the reason each tab differs. `langgraph dev` fails
to load a graph compiled with a custom checkpointer (reproduced), while
the FastAPI tab needs one because `ag-ui-langgraph` calls
`graph.aget_state(...)`, which raises `ValueError: No checkpointer set`.
- Narrow the shared `uv add` line to what both tabs import, and warn that
a project with exact pins should add them by hand.
A2UI fixed schema (`generative-ui/a2ui/fixed-schema.mdx`):
- Add the missing install step for `@copilotkit/a2ui-renderer` + `zod`,
which the catalog/definitions/renderer snippets all import.
- Add a `StateGraph` + `ToolNode` form for developers who already have a
hand-built graph, gated to the Python LangGraph slugs by a new
`a2ui_agent_form` docs flag so the shared page does not show Python to
langgraph-typescript or LangGraph code to LlamaIndex/ADK/Mastra.
- Repoint the cross-tree `/integrations/langgraph/...` link, which 301'd
back to this same page, at the action-handler reference it promises.
Raw Markdown pipeline (`src/lib/llm-text.ts`):
- `renderPageToLlmText` never applied `filterFrameworkScopedBlocks`, so
`/<framework>/<page>.md` emitted every `<WhenFrameworkHas>` branch with
raw JSX tags, each carrying the one selected framework's snippet. On the
A2UI page that produced three mutually-exclusive "how the schema is
delivered" sections whose prose contradicted the identical code under
each. Gate on the same framework the snippets resolve to, with a
regression test.
Also corrects a factually wrong comment in the langgraph-python showcase
`.env.example` that claimed 8123 was the `langgraph dev` default — the
same mis-belief this ticket found in the docs.

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.
