The short answer
Test conflicting-document behavior by supplying plausible sources that disagree and defining which authority, date, and scope should govern the answer. When that information is missing, evaluate whether the system clarifies or reports the conflict instead of inventing a resolution.
What to take away
- Document recency is not the same as document authority.
- Score the whole answer against all required constraints.
- Include cases where clarification is the correct outcome.

Enterprise retrieval is not always clean
EnterpriseRAG explicitly includes factual conflicts and knowledge gaps alongside retrieval noise. Its 2026 preprint reports that satisfying individual constraints can mask failure to satisfy them together. The practical implication is to create tests for combinations of requirements, while keeping the benchmark’s reported results within its own study conditions.
Write the source-resolution policy first
Decide which sources are authoritative for each task and how versions are interpreted. A more recent draft may not supersede an approved policy. A regional addendum may override a general rule only for particular users. Encode these relationships in retrievable metadata where possible rather than expecting the model to infer them from wording.
Distinguish publication date, effective date, and retrieval time. They answer different questions. A document published today can describe a rule that takes effect next quarter. The evaluation reference must specify the date relevant to the user’s request.
Construct controlled conflict cases
Rubrex recommends starting with a supported, unambiguous case and introducing one conflict at a time. Add an obsolete version, an unsigned draft, a region-specific exception, or a document without an effective date. Preserve plausible formatting so the task resembles actual retrieval.
Define expected behavior before running the system. Sometimes it should choose the approved current policy. Sometimes it should ask which date or region applies. Sometimes it should surface the disagreement and defer. A test that always rewards a decisive answer will discourage appropriate uncertainty.
| Condition | Expected response |
|---|---|
| Approved policy plus obsolete version | Use the applicable approved version and explain scope |
| Two equally authoritative conflicting rules | Acknowledge conflict and request resolution |
| Future effective date | Separate current behavior from the announced change |
| Missing region or account context | Ask for the information needed to choose a rule |
Illustrative example: a draft is newer
A support assistant retrieves a current refund policy and a newer draft with more generous terms. It chooses the draft because it has the latest timestamp. The failure is not simply a stale-data problem; it is a missing distinction between approval state and recency.
Test a metadata-aware retrieval change or a source-selection rule. Include a control where the newer document really is the approved replacement. Otherwise a fix that always favors older documents could pass the original example while creating a different class of error.
Keep conflict evidence in the readout
Record the source versions, authority assumptions, expected resolution, and actual answer. Track unsupported resolutions separately from explicit refusals or clarification requests. The goal is to understand whether the assistant handles uncertainty appropriately, not to maximize the number of questions it answers without interruption.
Limits of the evidence
The conflict policy must come from the product’s real operating rules. This article does not define legal or organizational authority for your documents. EnterpriseRAG is a preprint, and its benchmark findings do not establish your application’s failure rate.
Common questions
Should the newest source always win?
No. Approval status, effective date, region, and task scope may matter more than publication time.
Is asking a clarification a failure?
Not when the task genuinely lacks information required for a correct decision. Score whether the clarification is necessary and useful.
