A dependency upgrade risk and migration planning tool. Give it a repository and a version change; it tells you what will break, how risky it is, what evidence supports that assessment, and what to do about it.
The distinguishing constraint: every claim traces to a real line of code or a real source document. File and line numbers come from AST analysis, not from a language model. Breaking changes come from retrieved documentation, not from a hardcoded table. Where evidence is missing, the report says so and caps its own confidence.
