+# Copilot Code Review Instructions
+
+## E2E Test Requirement
+
+Every pull request that introduces a new feature **must** include at least one
+end-to-end (e2e) test covering the happy-path behaviour of that feature.
+
+- E2E tests live under `tests/e2e/`.
+- If a PR adds new user-facing functionality and does not add or update an e2e
+  test, flag it as a required change.
+- Bug-fix or refactor PRs that do not change observable behaviour are exempt.
