Goal with test-suite oracle

Give a long-running agent migration a hard finish line by requiring it to satisfy an existing test suite.

Engineering Jason Liu migration goals tests

Use this when a large task needs an external oracle instead of vibes.

Identify the reference implementation and test suite.
Make the success condition explicit: the new implementation must pass those tests.
Run the tests before changing code and record the baseline.
Implement in small passes.
Rerun failing tests after each pass.
Keep a compatibility ledger for known gaps.

Stop when the reference suite passes or the blocker is precise enough for a human decision.
