Which source actually supports the claim? An evaluation brief for public-sector services.
Which source actually supports the claim?
Attribution becomes useful when it connects a statement to evidence that a reviewer can inspect. A list of plausible sources is only the start of the investigation. A public-sector team is evaluating an assistant that organizes guidance and prepares draft answers for staff review. Published guidance can change, and a confident answer can obscure the source, applicability conditions, or authority behind a statement.
A practical starting point
For this evaluation, trace one consequential claim back to the specific evidence that supports it. Separate factual support, textual similarity, conceptual relationships, and claimed intellectual-property dependence. Those relationships answer different questions. Preserve the particular passage or technical feature that motivated each match, together with its source identity and context. The immediate concern is whether an answer derived from superseded guidance is presented as the current basis for a consequential decision. The review should make that possibility testable, rather than relying on the apparent fluency or completeness of the output.
Examine the boundary
Include a retired guidance document alongside its replacement and ask a question whose answer depends on the revision. Ask whether the source supports the exact statement being made, whether important qualifications were lost, and whether another source provides a better explanation. Treat missing evidence as an unresolved question rather than filling the gap with a confident narrative. Bring the service owner and the authority responsible for the underlying guidance into the review when the finding affects an operational or institutional decision. Their role is to connect the evidence with the authority needed to act on it.
Keep the evidence connected
Use a response record showing the applicable source version, cited passage, unresolved question, and reviewing staff role. Record the claim, candidate sources, relevant passages, competing matches, and the reviewer's conclusion. A later reviewer should be able to see the original question, the observations that mattered, and the point at which the team moved from investigation to a decision. Preserve contradictions and unresolved questions alongside the outcome.
From evaluation to use
Use the assistant to support preparation and review. Establish how staff identify authoritative guidance and handle cases that cannot be resolved from the available record. A source match does not establish that a model was trained on a work, nor does it independently determine ownership, infringement, or permission to use the result. The practical next step is a bounded review with an identified owner, a stated question, and an evidence package that supports the decision.
