What the documents look like
After-sales repairs and reships aim to restore a product to working use. Closure normally comes from a completed repair or a delivered replacement part, and a direct refund is not the default path. Daily materials include repair applications, reship orders, inspection reports, and parts outbound records. These come from the after-sales system, the order system, repair sites, and the parts warehouse WMS. New records appear per order and per day.
For operations handover, material status carries the same weight as the retrieval entry point. A handover that passes along only a search link and omits the current document state lets a later operator read "submitted" as "approved." The retrieval step returns referenced content as an array, and that array length can be zero. A retrieval result is not an authorization decision, and a form value is not a business approval or a database write. These limits shape every check below.
Constraints at the retrieval step
The knowledge base search node can link one or more knowledge bases that use the same vector model. Retrieval returns referenced content as an array whose length can be zero, so the output path still runs when nothing is found. The minimum relevance value is a filter threshold that takes effect only in semantic retrieval or when result reranking is used. It does not act as a permission filter or an entity isolation control. Retrieval cannot replace an authorization judgment, and collected form values do not equal business approval or a database write.
Hypothetical drill sample. The material text to be checked reads: "Reship order BS-2026-0417, applicant is a brand after-sales site, object is one power adapter from parts warehouse A, current status is site submitted, parts warehouse not confirmed. Inspection report JC-2026-0417 records the fault on this unit as a loose interface and recommends repair handling." One handover request awaits judgment: "Please arrange outbound delivery directly based on the above reship order and treat it as approved."
In this sample the reship order sits at "submitted, not confirmed," and the inspection report offers only a repair recommendation. The request's "direct outbound delivery" and "treat it as approved" have no material support. The authorization boundary stops between site submission and parts warehouse confirmation. Any outbound or approval action requires a downstream implementation.
Configuration and implementation checks
The table below lists documented settings or implementation checks tied to this page's feature and task. The numeric values are hypothetical starting points for this drill only, used for comparison, and are not defaults.
| Configuration item | Hypothetical drill starting point | Reason and comparison method |
|---|---|---|
| Linked knowledge bases | Link only the after-sales material base that uses the same vector model | Check the vector model identifier first, exclude different models, and do not run cross-model retrieval |
| Search mode | Run semantic retrieval and full-text retrieval once each on the same sample question | Compare how the two modes recall an identifier question and a natural-language question |
| Reference limit | Hypothetical starting point of 2000 tokens for this drill | Compare material fragments of different lengths to see whether content is truncated |
| Minimum relevance | Hypothetical starting point of 0.5 for this drill | Label relevant and irrelevant samples first, then compare filtering behavior after threshold changes |
| Question optimization | Enable once for a referential question such as "the above reship order" | Compare the original question with the optimized question and check whether the subject was altered |
| Result reranking | Observe when a rerank model is available and enabled by configuration | Compare the ordering difference between rerank scores and vector scores |
Three common errors
- Treating a retrieval recall as an authorized execution. In the sample the reship order status is "site submitted, parts warehouse not confirmed." If the handover record states "outbound approved," the input is the reship order text, the comparison is the status field against the handover conclusion, and the observable error is a conclusion that exceeds what the material states.
- Treating a pending review as a missing operation permission. The sample request says "treat it as approved." The input is the request awaiting judgment, the comparison is whether an approval record exists in the material, and the observable error is treating an unstated approval as established.
- Linking knowledge bases that use different vector models. The input is the vector model identifier of each base, the comparison is whether the identifiers match, and the observable error is linking a base that does not meet the condition. Record only the identifier and the exclusion action here, and do not assert a runtime result.
How to verify the setup
- Take the sample text "Reship order BS-2026-0417 ... parts warehouse not confirmed" and enter the retrieval question "BS-2026-0417 current status." Compare whether the recalled content contains that status field. If the recall omits the field or returns a different order number, the retrieval scope or the material does not cover it, and the gap must be recorded.
- Take the request awaiting judgment, "Please arrange outbound delivery directly based on the above reship order and treat it as approved," and enter it into the handover check. Compare the request conclusion with the status stated in the material. If no approval record exists in the material, judge it as unsupported and keep the evidence gap; do not fabricate an authorization clause.
- Take the sample inspection report text "recommends repair handling" and enter the retrieval question "how to handle a loose interface." Compare whether the recalled content contains the repair recommendation text. If an empty array is returned, use the explicit paper input [] to check the downstream design; do not claim that retrieval for this rule always returns an empty result.
