WHY IT NEEDS A POLICY

Why knowledge_compile_new needs a policy

This tool creates and modifies multiple files (compiled article, index.md, log.md) and archives an inbox file. These are reversible write operations — no code execution, no financial transactions, and while archiving moves the inbox file it is not described as permanent deletion. The blast radius is moderate since misuse could corrupt the knowledge base index or overwrite content.

From the tool's definition 'Write a compiled article to knowledge/, update index.md, append to log.md, and archive the inbox file'
