How much do we know?
A source is a published page or document behind a claim. The label measures what is documented, not whether a system is good or safe. Missing information does not prove that a safeguard is missing.

The interface and explanatory guides are translated. Record names, record descriptions, quotations, detailed editorial notes, and linked public documents stay in their published language so evidence is not silently changed.
If this affects someone
Human review is typically used during the model training and quality assurance process to quantify accuracy. In use cases where Splink provides a list of possible matches to a human, the human then makes the final decision.
There are no complaint procedures specific to Splink itself since it does not directly make decisions about individuals. However, there is a formal complains procedure for the various parts of the justice system which could be used if something was perceived to have gone wrong. Where linkage errors are identified, it is possible to record manual overrides in the system to prevent them re-occuring.

The score orders work, not people.
Review priority rises for rights-sensitive uses, missing sources, unanswered accountability fields, and old evidence. Strong official documentation lowers it. The score is not a verdict on safety, fairness, or legality.
A missing field means the attached public sources did not answer it. Coverage is uneven, publication does not prove performance, and a certificate has a defined boundary.
