WHAT IT DOES

WHY IT NEEDS A POLICY

Why force_reaction_link needs a policy

This tool creates or modifies a link between a PDF page and an RDF reaction, which is a write operation that modifies stored data. The 'overriding confidence rules' aspect is concerning as it bypasses safety checks, elevating severity to high. It's not Destructive since the original data isn't deleted — the link is being established/overwritten rather than data being purged.
