-Run the first three before every push (deterministic, no server needed). Add tests for new logic.
+
+**ALL existing tests must pass before pushing.** Run at minimum:
+```bash
+node test-packet-filter.js && node test-aging.js && node test-regional-filter.js && node tools/e2e-test.js && node tools/frontend-test.js
+```
+If any test fails, fix it before pushing. No exceptions. No "known failures."
+
+**Every new feature must add tests.** If you add logic, add tests. If you fix a bug, add a regression test. Test count should only go up, never down.
 
 Tests that hit live data can use `https://analyzer.00id.net` — all API endpoints are public, no auth required.
