"""
Drift detector for the dashy openpilot-settings mirror.

We expose upstream openpilot's TogglesLayout + DeveloperLayout settings via the
dashy web UI by mirroring them into dragonpilot/settings/openpilot.*.py. This
test fails loudly when upstream adds or removes a toggle key — preventing the
mirror from silently going stale on the next openpilot version bump.

If upstream renames a key, add/remove the corresponding entry in the mirror file.
If upstream adds a brand-new toggle, decide whether to mirror it (most should)
and add a new entry. If upstream removes one, remove it from the mirror.
