How FlowCheck works

We pull every public template from the n8n template library and read its workflow JSON. Each node is compared with the list of nodes, node versions, parameters and expression helpers that the official n8n 3.0 breaking changes remove.

• Ready for 3.0: nothing removed in 3.0 was found. Warnings (deprecated nodes, behavior changes) may still apply.
• Needs changes: at least one removed node, node version, parameter or helper. We list each one and its official replacement.
• Unknown: uses community nodes we can't verify, or the template has no workflow JSON.

This is a static check. Live test runs in a real n8n 3.0 instance are coming next.
