# 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). When comparing test-suite size, diff the **test name list**, not the `# tests` summary. `# tests` can drop TAP rows when a test swallows `process.stdout` (BUG-995). Baseline vs delivery: ```bash npm test 2>&1 | grep -E "^(not )?ok [0-9]+ - " | sed -E 's/^(not )?ok [0-9]+ - //' | sort > /tmp/names.txt ``` Run that twice and `diff` the two files. New names are allowed; disappearing names are not.
