Gate Weighted Groups by Product Conditions
Weighted Groups can now be gated by per-product conditions at two levels. Add an "Only when…" to the whole blend from the group settings sheet to skip the entire weighted score for products that don't qualify, or add one to a single feature row to scope just that signal — the rest of the blend still ranks the product on its own terms.
A product that fails either gate doesn't score zero: it falls through to the next expression in the sort order, the same fall-through behavior conditional sort expressions already use for metrics and attributes. Use a feature-level gate to keep a noisy signal like conversion rate from counting until a product has enough orders to trust it, or a blend-level gate to scope an entire "best match" ranking to products currently on sale.
