Arc Email
Start with one relief pass.
Arc makes one read-only pass and shows only what it has enough proof to place.
First pass
Arc is making your first pass.
Beta boundary
The test is relief.
Arc should reduce the load by showing only what it has enough proof to place, and by leaving everything else unguessed.
This beta is currently running deterministic, product-safe rules. The Arc can hold items only when there is a clear reason to bring them back later.
