Same defect as the mastra cell, same page: the `backend-render-operations`
marker is hoisted to the top of `agents/agent.py`, so
`/aws-strands/generative-ui/a2ui/fixed-schema` published 586 lines of a
1688-line module — the messages-snapshot wrapper, the weather/dice/query
tools, everything — instead of the A2UI tool the step is about.
Move `generate_a2ui` and its `_A2uiError` shape into
`agents/a2ui_generate.py`, which is what `gen_ui_agent.py` /
`a2ui_dynamic.py` already do for their own surfaces ("this module lives in
its own file so the surface area is reviewable in isolation"). `agent.py`
imports the tool back for the shared agent's tool list, so the wiring and
the tool id are unchanged; the published snippet is now 171 lines with its
own imports. `tools/generate_a2ui.py` joins the cell's highlighted files so
the guide also shows the helper the tool calls.
The error-handling suite patched `agents.agent.build_a2ui_operations_from_tool_call`,
which now lives on the new module — retargeted, and it still imports the
tool via `agents.agent` so the re-export stays covered.

Replace sys.path.insert hacks in Python agent files with direct
imports via symlinks to shared/{python,typescript}/tools.
Update Dockerfiles, entrypoints, and configs to support the new
symlink-based tool resolution. Add PARITY_NOTES for frameworks
that have known gaps.
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.
