LLM Language Refactoring & ReGrade

When your team migrates code between languages, ReGrade compares responses to recorded requests across versions. Review the observed differences before approving the migration. Memory-safety validation remains a separate step.

The Refactoring Loop

  1. 1Record requests and responses from the reference application
  2. 2Create the candidate implementation in the target language
  3. 3Replay the recorded requests against the candidate build
  4. 4Compare responses and investigate unexpected differences
  5. 5Fix unexpected differences and replay the recorded requests again
  6. 6Approve the migration after reviewing behavioral evidence

Then the loop repeats from step 1.

Benefits

Behavior checks during migration

Check responses to recorded requests at each step of the migration.

Automated equivalence testing

Field-level comparison catches behavioral differences that unit tests miss during language transformations.

Confident language migrations

Compare observed responses across language versions. Unexercised paths still need testing and review.

Checks on every iteration

Each LLM-driven transformation is replayed against the same recorded requests, so every iteration gets the same behavioral check.
