Our summary
A database migration changes how information is stored and can delete tables or columns. TypeSafe Migration Guard receives the proposed statement and whether it targets a live system. It asks Jev for a SAFE or DANGER label, then returns an allow or block response.
The documented release process starts a web service and checks pending change files. A DANGER answer for the live environment stops deployment with a refusal response. The repository demonstrates one example that creates a table and another that deletes a table.
Those two examples do not prove safety for every change. The source does not document a separate exact safety check or a route for uncertain answers. JevMade recommends human review, realistic database tests, backups, and a tested recovery plan; a model label alone is not enough.
Key takeaways
- The documented gate relies on one SAFE or DANGER model label.
- Treat the two demonstrations as examples, not general proof.
- Add human review, realistic tests, backups, and recovery checks before live use.
