What the documents look like
Group-buy presale collection takes orders first and organizes purchasing and fulfillment afterward. This differs from leader relationship management, which is a separate line of work. The daily materials for a presale collection cycle are the presale product table, the collection result, the purchasing plan, and the cut-off notice. Their sources include mini-program orders, supplier inventory, leader feedback, and warehouse routing. In cross-border material and multilingual retrieval work, the product table may carry product names and origin descriptions in more than one language, and the cut-off notice and purchasing plan need to be checked across languages. These materials update on a daily or per-session rhythm. Workflow routing here covers material collection, language identification, and retrieval handoff. It does not perform order writes or inventory synchronization.
A presale collection cycle is organized around a session, and the cut-off notice marks the point after which purchasing is arranged. The purchasing plan can still be at a stage where a supplier has not confirmed. That stage is a status value inside the document, and it is not the same fact as supply being arranged or a purchase being completed.
Constraints at the workflow routing step
The form input node is a user interaction node. When it is triggered, the conversation enters an interaction state, the workflow state is recorded, and execution continues after the user completes the interaction. The node collects the required information the user fills in, and after submission it passes that information to later nodes. The user selection node is also a user interaction node. When the user makes a choice, the node judges the choice and executes the corresponding branch.
Several constraints follow for this task. The interaction state is recorded by the interaction node. No separate global state-recording switch is documented. Values collected through retrieval or a form do not constitute authorization. Order writes, document backfill, and external status synchronization each require a separate business interface or a later process. Semantic recall and relevance scores do not perform permission or entity isolation. Libraries that use different vector models cannot be associated together; their identifiers must be checked first and non-matching libraries excluded.
Hypothetical drill sample. A platform operations staff member submits a handover request. The source material reads: "Presale product table (session 12) lists 'Chilean cherries 2 kg'; the cut-off notice states 'cut-off time 18:00'; the purchasing plan states 'awaiting supplier confirmation'." The proposed draft sentence reads: "This session's cherries have confirmed supply and purchasing is complete." The request contains the subject (platform operations staff member), the object (session 12 presale product), the status (awaiting supplier confirmation), and the scope (cut-off notice and purchasing plan). Judgment must compare the same subject, the same period, and the same field. The purchasing plan field is "awaiting supplier confirmation," while the draft sentence says "confirmed supply and purchasing is complete." These two values are mutually exclusive on the same field, so the draft sentence is not supported. A quotation validity period does not indicate a supply period. A pending review does not demonstrate a lack of operating permission.
Configuration and implementation checks
| Configuration item | Type | Description |
|---|---|---|
| Form input node | Interaction node | Enters the interaction state when triggered, collects required information, and passes it to later nodes after submission |
| User selection node | Interaction node | Executes the corresponding branch after the user makes a choice; verify each branch connection |
| Output handoff | Implementation check | Pass collected information explicitly to later retrieval, judgment, or interface nodes, and compare each output against its input |
| External operation division | Implementation check | Order writes, document backfill, and external status synchronization each require a separate business interface or a later process |
| Retrieval library identifier check | Implementation check | Libraries using different vector models cannot be associated together; check identifiers first and exclude non-matching libraries |
| Empty-result handoff | Implementation check | A paper input of [] can be used to check the downstream design; do not claim that a fictional rule retrieval will necessarily return [] |
Hypothetical trial starting point: set the retrieval return count to 5. The reason is that the sample material for this session contains only 4 documents, and the aim is to observe whether all are covered. Compare against the total of 4 documents; if the return count is less than 4, record the gap. This value is a hypothetical trial starting point for this page, not an official default.
Three common errors
- Treating a value collected by the form input node as authorization to execute. Symptom: after receiving a purchasing plan that states "awaiting supplier confirmation," the draft sentence is written as "confirmed supply and purchasing is complete." The input is the purchasing plan text, the compared field values are "awaiting supplier confirmation" and "confirmed supply and purchasing is complete," the two are mutually exclusive on the same field, and the draft sentence is not supported.
- Treating semantic recall or a relevance score as permission or entity isolation. Symptom: assuming that a result with a high relevance score has access rights. The input is the relevance score returned by retrieval, the comparison object is the access permission list, the score does not constitute a basis for permission, and authorization status must be checked separately.
- Associating libraries that use different vector models. Symptom: directly associating two libraries with different vector models and then comparing missed recall. The input is the model identifiers of the two libraries; compare whether the identifiers match, exclude a library when they do not match, and do not run a cross-model retrieval comparison.
How to verify the setup
- Check the draft sentence against the hypothetical sample source text. The input is the purchasing plan text "awaiting supplier confirmation" and the draft sentence "confirmed supply and purchasing is complete." Compare whether the two values on the same field are mutually exclusive. If they are mutually exclusive, the draft sentence is not supported, and the evidence gap is recorded.
- Check empty-result handoff with a paper input of []. The input is an explicit empty array. Compare whether the downstream node is designed to handle an empty result, and observe whether undefined behavior appears. Do not claim that a fictional rule retrieval will necessarily return [].
- Check retrieval library identifiers and output handoff. The input is the vector model identifiers of two retrieval libraries and the form output fields. Compare whether the identifiers match and whether the output is explicitly passed to later nodes. When the identifiers do not match, exclude that library and record the actual observation.
