"""Structural alignment tests — every adapter must agree with the registry.
The registry in workspace/platform_tools/registry.py is the single source
of truth for tool naming + docs. These tests fail if any consumer
(MCP server, LangChain @tool wrappers, doc generators) drifts.
If you add a tool: append a ToolSpec to registry.TOOLS, then add the
matching @tool wrapper in builtin_tools/. These tests catch the case
where the registry has a name that has no LangChain @tool counterpart
(or vice versa).
If you rename a tool: edit registry.TOOLS only. These tests fail loudly
if the LangChain @tool name or MCP TOOLS["name"] still has the old name.
