# Validation Migrate Studio is a developer tool. It is not validated software, and it makes no Part 11 claims. `history.json` is an operational log: the operator name comes from Profile, which the operator can edit, so it is not an attributable audit trail. The rule books shipped in this repository are worked examples, and each edition's rules are scoped to one migration direction. Any rule applied to submission-bound code should be qualified under your own SOPs, with paired before/after programs as evidence. Before regulated use, qualify the exact edition, rule book, runtime version, browser, and deployment mode. Keep the evidence outside this repository unless it has been explicitly cleared for publication.
