What the documents look like
Brand after-sales repair service centers on warranty responsibility and physical repair locations. This differs from e-commerce platform after-sales, which handles platform refunds. The daily materials are warranty cards, repair work orders, inspection reports and exchange approvals. These materials carry the purchasing party, the faulty object, the repair status and the approval conclusion. Comparison work checks field by field whether these values agree within a single order. Data sources cover the after-sales system, store orders and repair location feedback. The update frequency given is per order and daily; that frequency does not change the comparison logic on this page.
A hypothetical paper exercise sample is used throughout this page. A brand after-sales center receives paper materials. The warranty card states: "Purchaser: A, product number P-001, purchase date 1 March 2024, warranty period twelve months." The repair work order states: "Sender for repair: A, product number P-001, fault description: will not power on, receipt date 5 November 2024." The inspection report states: "Product number P-001, inspection conclusion: mainboard fault, within warranty scope." The sentence proposed for checking is: "The product is within the warranty period and the fault is within warranty scope." The materials do not state an exchange approval conclusion. That field remains unsupported.
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 the workflow continues after the user completes the interaction. It collects required information the user fills in and passes that information to later nodes. The User Selection node is also a user interaction node. When the user makes a selection, the node judges that selection and executes the "yes" branch. The documentation does not describe a global state-recording switch, a submission-count limit, or an automatic judgment mechanism. Nodes only accept input and route branches. Order writes, document backfill and external status synchronization require a separate business interface or a later process.
Retrieval and form collection do not constitute authorization. A pending review state does not show that an operation permission is absent. A similarity or relevance score is not a category, entity or permission filter, so it cannot be used to exclude unrelated businesses or unauthorized records. Retrieval is not authorization. Knowledge-reference limits use the documented unit, and same-model retrieval association, empty-reference output and context limits keep their documented conditions. Libraries using different vector models cannot be associated together; check identifiers first, exclude those that do not match, and record the actual observation.
For this sample, the form input node collects the product number and purchase date fields. The user selection node is used for the warranty scope branch. The output must be passed explicitly to the later retrieval or judgment node. The comparison checks the product number against the inspection conclusion. The exchange approval conclusion is not produced inside these nodes.
Configuration and implementation checks
| Configuration item | Setting or check on this page | Relation to the sample |
|---|---|---|
| Form Input node | Enters interaction state when triggered, collects required information, passes it to later nodes | Collects product number and purchase date fields |
| User Selection node | Executes the corresponding "yes" branch after the user makes a selection | Used for the warranty scope branch |
| Output handoff | Passes collected information explicitly to a later retrieval or judgment node | Compares product number with inspection conclusion |
| Retrieval scope | Retrieves materials only within the target scope the user has access to | Retrieves warranty card, work order, inspection report |
| External operation division | Order writes and external synchronization require a separate interface or later process | Exchange approval conclusion is not produced inside the nodes |
| Hypothetical trial starting point | This sample uses purchase date plus twelve months as the warranty end date, compared with the receipt date | This starting point is a hypothetical value for this exercise, not an official default |
Three common errors
- Treating form collection as authorized execution. The Form Input node only collects required information and passes it to later nodes. The sample does not state an exchange approval conclusion, so a submitted form does not mean the approval passed.
- Treating a retrieval hit as a permission filter. A similarity or relevance score does not perform permission or entity isolation. The sample materials must be checked within a target retrieval scope the user has access to, and any gap is recorded as a gap.
- Mixing different parties or periods when judging a contradiction. In the sample the purchaser and the sender for repair are both A, and the product number is P-001 in both. If another party or period is substituted, the result can only be recorded as unsupported or pending verification.
How to verify the setup
- Enter the sample warranty card, repair work order and inspection report text. Compare whether product number P-001 agrees across all three materials. When all three agree and the purchase date plus twelve months is later than the receipt date, the within-warranty-period judgment holds.
- Enter the proposed sentence "The product is within the warranty period and the fault is within warranty scope." Compare whether the inspection report conclusion field states "within warranty scope." When it does, that clause holds. The exchange approval conclusion is not stated, so it remains pending verification.
- Use the paper input
[]to check the empty-result handoff design. Observe whether the downstream node handles it as empty input. This check does not claim that a fictional rule retrieval must return an empty result. Libraries using different vector models cannot be associated together; check identifiers first, exclude those that do not match, and record the actual observation.
