Made the test finder check products against each visitor's requirements

On 5 October 2026, the test finder gained a product shortlist checked against the visitor's sample, budget, evidence preference and optional country requirements. It displays prices, price notes and verification dates, explains why other products require a trade-off, and states when no listed product meets every requirement. The Compare handoff keeps those requirements, and a decision summary can be shared or printed. The underlying clock-family recommendation weights and catalog evidence tiers did not change.

Previously, handing only the recommended clock family to Compare could show products that contradicted the visitor's sample or budget requirements. The new shortlist makes those constraints and their trade-offs explicit.

Visitors can see which listed products meet their stated requirements and which do not. Budget checks use the catalog's US-dollar price bands. Promising is disclosed as the highest evidence tier reached by any listed test; the shortlist is not proof that a report will answer the visitor's question, and a biological-age result is not a diagnosis.
