+These tests run in a real browser using Playwright and pytest.
+
+Important: For the initial smoke baseline, you must start the server yourself (for example, python -m scidk.app) and set the BASE_URL environment variable for the tests to know where to connect (e.g., http://localhost:5000). The tests are headless by default and designed to be fast and deterministic.
 
 Prereqs (once per machine):
 - Python virtual environment activated.

 - Unit tests and smoke checks run on every PR.
 - E2E smoke (where applicable) runs within a few minutes (<5s/spec target).
 - Required checks must be green before merge.
+- Dev submodule freshness: PRs to main must keep dev/ submodule at the latest commit of its configured branch (see .gitmodules). A CI check enforces this, and main auto-syncs dev/ after merge.
 
 ## Tips
 - Use `python -m dev.cli ready-queue` to confirm current priorities.
