What the documents look like
Cross-border return refurbishment and resale handles reverse logistics and item condition, which differs from overseas-warehouse inbound replenishment. The main data sources are the overseas warehouse WMS, the TikTok return center, Amazon return reports, and item inspection photos. Daily documents include the return inspection form, the refurbishment record, the scrap form, and the resale listing list. Data updates daily or per batch. These materials together determine whether a returned item can enter refurbishment and whether it can be relisted, and they define the handover boundary for operations permissions among the seller, overseas warehouse inspection, and the after-sales supervisor. Citation tracing addresses one question: during handover, does a cited material actually exist, is its version valid, and is its authorization state explicit.
The knowledge base search node can select one or more knowledge bases that share the same vector model. Its output is an array of cited content, and the length may be 0; when nothing is found, the output path still completes. Search results are candidate materials only and do not constitute authorization. The minimum relevance score is a filter threshold that takes effect only under semantic search or result reranking; it does not perform permission isolation or entity filtering. Hybrid search fuses multiple result paths through RRF, reranking requires a rerank model and must be enabled by configuration, and image retrieval requires the corresponding image input and model capability. These conditions mean handover decisions must return to the specific source text, and neither a retrieval score nor a citation count can serve as authorization evidence.
Constraints at the citation tracing step
A paper exercise sample is given here. On 10 June 2025, an after-sales supervisor at a cross-border seller hands over a batch of returned goods. The supplied return inspection form reads: "Inspection No. T-20250610-07, item: Bluetooth earphones, quantity 40, inspection conclusion: appearance intact, function pending retest, retest responsible party: overseas warehouse A, retest completion deadline: 12 June 2025." The refurbishment record for the same batch reads: "Refurbishment No. R-20250610-07, corresponding inspection form T-20250610-07, refurbishment content: packaging replacement, status is pending inspection confirmation." The draft sentence to be assessed in the handover request is: "These 40 Bluetooth earphones have completed refurbishment and can be added directly to the resale listing list." The comparison required is as follows: the refurbishment record status is "pending inspection confirmation," and the inspection conclusion is "function pending retest." Neither shows that the retest is complete or that inspection has been confirmed. The draft sentence's "have completed refurbishment" does not match the status recorded in the materials, and "can be added directly" lacks an authorization basis. This is a paper exercise and does not indicate that any actual business action occurred.
Because retrieval returns candidate materials rather than approvals, the citation tracing step must compare the draft sentence against the source text field by field. A pending retest is not a completed retest. A refurbishment status of pending inspection confirmation is not a completed inspection confirmation. A retrieval hit on a refurbishment number is not an approval to relist. Where a material does not record a field, that field remains unknown rather than negative.
Configuration and implementation checks
| Configuration or check item | Purpose on this page | Conditions and observations |
|---|---|---|
| Associated knowledge bases | Limit the retrieval scope for this handover material | Select only knowledge bases with the same vector model; verify identifiers first and exclude those that do not match |
| Citation upper limit | Control the token volume cited in one search | For this paper exercise, set a smaller starting value, because handover materials require item-by-item checking; compare citation completeness against a larger value |
| Minimum relevance score | Filter low-relevance retrieval results | Takes effect only under semantic search or result reranking; does not carry permission filtering |
| Search mode | Choose semantic, full-text, or hybrid search | Number and document-number queries favor full-text or hybrid; RRF is a fusion process, not a switch |
| Result reranking | Reorder candidate text | Requires a rerank model enabled by configuration; the score is used for filtering, not for authorization |
| Cited content output | Carry retrieval results forward | Output is an array whose length may be 0; an empty array requires separate checking of downstream design |
The smaller citation upper limit is a hypothetical starting value for this exercise, chosen because handover materials need to be checked one by one, and it is compared against a larger value to observe whether citations remain complete. It is not an official default. The reranking path and the image retrieval path are optional paths listed in the overall retrieval flow and are not executed on every request; reranking requires a rerank model enabled by configuration, and image retrieval requires the corresponding image input and model capability.
Three common errors
- Treating a retrieval hit as authorization. The input is the inspection form and refurbishment record above. If the presence of refurbishment No. R-20250610-07 in the retrieval results is used to decide that relisting is permitted, the comparison object is the authorization status field, and the observable result is that the materials contain no inspection confirmation or relisting approval record. The decision is not supported.
- Confusing "pending retest" with "completed." The input is the inspection conclusion "function pending retest" and the refurbishment status "pending inspection confirmation," while the draft sentence states "have completed refurbishment." The comparison is the same field of the same object, and the observable result is that the two values are mutually exclusive, which constitutes a contradiction.
- Treating the minimum relevance score as a permission filter. The input is the handover request. If a relevance score is used to exclude unauthorized records, the comparison object is the permission field against the score, and the observable result is that the documents do not state that the score performs permission filtering. The practice lacks a basis.
How to verify the setup
- Check the cited source text against the paper sample. Input the source text of inspection form T-20250610-07 and refurbishment record R-20250610-07. Compare the draft sentence "have completed refurbishment" against the status fields in the materials. The expected observation is that the statuses do not match, and the item is judged as pending verification.
- Check downstream handling with an empty citation output. Input a paper retrieval result array
[]. Compare whether the downstream node continues execution as designed for an empty array. The expected observation is that the path completes and no relisting action is produced; actual behavior is subject to runtime observation. - Check the association scope against the same-vector-model condition. Input two knowledge base identifiers. Compare whether their vector models are the same. The expected observation is that those with different models are excluded; record only the actual observation and do not infer runtime results of associating different models.
These checks test the named primary task of citation tracing for operations handover. They do not verify identity certification, report analysis, or any other task. Where a material field is not provided, it remains unknown. A pending request is not an approval, an offered option is not execution, and an unsigned termination is not a completed termination.
