What the documents look like
Brand livestream operations differ from influencer-hosted sessions in that the brand team itself carries the script, inventory, and after-sales work, and does not rely primarily on influencer commission. The daily document set for this category includes livestream scripts, product explanation cards, shift schedules, and livestream retrospectives. Transaction-side leads come from deal details and livestream comments. The comparison task covered here is contract-and-transaction material comparison: material source text is checked line by line against draft sentences or handover requests, and source evidence comes from traceable retrieval citations.
Two features of this category affect citation tracing directly. First, the same product may carry several explanation card versions across one day, so a citation must be tied to a version, not only to a product name. Second, a handover request often mixes several facts in one sentence, such as attendance, contract attachment status, and quotation validity, so each fact needs its own comparison rather than one overall judgement.
Retrieval output is an array of citations, and its length may be zero. An empty array does not mean the workflow has errored or terminated. The citation limit is measured in tokens. The minimum relevance value takes effect only under semantic retrieval or result reranking. Neither of these is a permission filter or an entity isolation mechanism, and retrieval is not authorization.
Constraints at the citation tracing step
Citation tracing begins by checking the selected knowledge bases and the material version. Only knowledge bases that share the same vector model can be associated together. Bases built on different vector models cannot be associated, so the check is to verify the identifiers and exclude those that do not match, not to run cross-model retrieval and compare what was missed.
Retrieval results must be passed to the answering stage, where each answer sentence is checked against the cited source text. Retrieval and form collection only produce values. Business verification, approval, database writes, and external synchronization each need their own downstream implementation. A pending review does not show that an operation permission is absent. Signing, reaching cooperation, and contract effectiveness are three separate facts. A quotation validity period does not state a supply period. A contradiction requires the same subject, the same period, and the same field with clearly exclusive values. A field that is not stated, or evidence that covers only a related stage, counts as unsupported or pending verification.
Hypothetical drill sample: a brand livestream team keeps a paper text titled Anchor Shift and Explanation Handover Sheet. The source text reads: "On 10 March 2025, Anchor A covers the 20:00 to 23:00 session, product explanation card version V3; the contract attachment for that day is pending review; the supplier quotation sheet is valid until 31 March 2025." The draft handover request to be judged reads: "Anchor A completed the explanation for that session on 10 March, the contract attachment is effective, the quotation validity covers the supply period, so write this into the deal details." This request turns a pending review into an effective status, extends quotation validity into a supply period, and lacks an authorization basis for writing into deal details. It is judged unsupported, and the evidence gaps are retained.
Configuration and implementation checks
| Configuration or check item | Hypothetical starting point for this drill | Reason and comparison method |
|---|---|---|
| Associated knowledge bases | Select one brand livestream material base with the same vector model | The document requires the same vector model for joint association; check base identifiers one by one and exclude bases on different models |
| Citation limit | Start at 3000 tokens | This is a hypothetical starting point only, chosen so the citation can be compared with the full handover sheet length and observed for coverage of key source sentences |
| Minimum relevance | Start at 0.4 | This is a hypothetical starting point only, compared with semantic retrieval or rerank scores to observe whether low-relevance fragments are filtered |
| Search mode | Hybrid retrieval | The handover sheet contains exact fields such as dates and version numbers, so hybrid retrieval with RRF fusion is used to combine multiple result paths |
| Result reranking | Enable ReRank | When candidates are numerous, second-pass ordering uses a 0-1 score compared against the minimum relevance value |
| Citation output handling | Pass the citation array to the answering stage | Check each answer sentence against the cited source text; treat a zero-length array as a downstream design check |
Three common errors
- Writing a pending review as effective. The input is the source sentence "the contract attachment for that day is pending review" and the draft sentence "the contract attachment is effective." The comparison is the status value of the same field, and the two values are exclusive, so the draft sentence is judged unsupported.
- Treating quotation validity as a supply period. The input is "the supplier quotation sheet is valid until 31 March 2025" and the draft sentence "the quotation validity covers the supply period." The comparison is the meaning of the field, and the source does not state a supply period, so the item is judged pending verification.
- Treating a retrieval hit as write authorization. The input is the citation array and the draft sentence "so write this into the deal details." The comparison is the authorization boundary, and the source states no write authorization, so the item is judged to lack an authorization basis, and the database write needs a separate downstream implementation.
How to verify the setup
- Compare the source sentence "On 10 March 2025, Anchor A covers the 20:00 to 23:00 session, product explanation card version V3" with the draft sentence "Anchor A completed the explanation for that session on 10 March." When the subject, date, and session match, the sentence is supported. When the session or date does not match, record it as unsupported.
- Compare the source sentence "the contract attachment for that day is pending review" with the draft sentence "the contract attachment is effective." When the same field holds exclusive values, record a contradiction. When the source does not state the effectiveness status, record it as pending verification.
- Check the downstream design with a clearly stated paper input of an empty citation array
[], and observe whether the answering stage continues under a zero-length output. This check does not claim that a fictional rule retrieval necessarily returns an empty array; the actual retrieval result is recorded as observed.
This page covers only brand livestream operations, contract-and-transaction material comparison, and citation tracing. During operational handover, the authorization status of materials, operations, and requests must be established separately; retrieval and form collection do not act as authorization to execute.
