# This is NOT the Next.js you know This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in `node_modules/next/dist/docs/` before writing any code. Heed deprecation notices. # Frontend change radius Before deleting or renaming a frontend symbol, class name, or visible copy, run `git grep -n "" -- tests/ frontend/` — not `frontend/` alone. `tests/` holds Python source-contract tests that assert on frontend text (`test_session_management_entrypoints.py`, `test_daily_and_rectification_entrypoints.py`, `test_birth_time_journey_contract.py`). Grepping only `frontend/` missed them four times (BUG-933, BUG-934, BUG-939, BUG-992).
