verify_integrity

MCP tool from Pdf Verify MCP by shuji-bonji

Tamper detection: incremental updates, changes after signing, DocMDP certification violations assessed per P value (below), and an object-level diff of the revision chain (which objects each update added, rewrote or freed). Incremental updates are legal, so the diff says what to review — no verdict
