What the documents look like
For product questions in Certificates of origin, this page examines FastGPT vector indexes. Product names, assembly locations and source references cannot combine into an origin attribute. The examples are hypothetical.
Constraints at the vector indexes step
A proposed product exercise within origin material names assembled components, refers final-assembly location to another page and marks current-batch source verification pending. A manufacturing-place question has no location in the name, an unread assembly page and an unresolved source. An entry saying locally manufactured components would add an unsupported attribute. Preserve product name, process location and batch source as separate subjects. Assembly wording cannot establish the complete manufacturing process, and missing location material also cannot establish the opposite geographic conclusion about the goods.
Configuration and implementation checks
| Original-data/index check | Specific subject relationship | Acceptance action |
|---|---|---|
| Name information | Assembled components | Do not add origin. |
| Process location | Final assembly separately referenced | Check process and goods. |
| Current-batch state | Source verification pending | Retain unresolved state. |
| Cross-batch target | Another batch location page | Check subject and applicability. |
| Confirmation adoption | New source and older application entry | Inspect actual cited version. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Embedding model | Knowledge bases associated with one search node must use the same embedding model. |
Original data and indexes | One original data block can have multiple indexes. |
Index content | Index wording should be complete and focused. |
Image indexes | Where image retrieval is used, inspect descriptions or image vectors. |
Version and result check | After a change, reuse questions to compare originals. |
Three common errors
First, a component name may be indexed as confirmed origin; inspect source wording linked to the goods. Second, a location question may target another batch assembly page; inspect goods, batch and process identity. Third, after source confirmation is added, an entry may still cite the earlier pending application; inspect new original data, target and actual adoption. These require added-attribute, applicable-subject and update-mapping checks. Titles and similar place names cannot complete verification, and these passages do not establish a certificate or compliance outcome for the actual transaction.
How to verify the setup
Acceptance should ask what the name states, whether the assembly page was obtained and the stage of current source confirmation. Keep citations and qualifications visible. The component name and pending scope can be reported, while manufacturing place still needs applicable material without invented geography. After addition, inspect actual processing and index state before checking same-question adoption. Several routes to one application note cannot become independent source evidence. Completing retrieval location also cannot establish that the separate business verification has been completed or that an eventual certificate decision is known.
