What the documents look like
Certificate of origin work turns on four document families: the certificate application, the commercial invoice, the packing list, and production cost records. These serve import-country tariff and customs clearance, and the binding source differs from letter-of-credit document examination. Daily data comes from China International Trade Single Window, CCPIT systems, enterprise production records, and customer clearance requirements. The brief lists per-order and batch update frequencies; this page's function does not depend on that frequency, so no synchronization mechanism is described here.
For conversation logs and audit, the unit of work is the session record and run detail attached to one certificate matter as it moves through inquiry, filing, and handover. Material identity and conversation identity must be matched separately by chatId and dataId. The chat interface documents that chatId as a non-empty string pulls the session from the database and uses the last messages entry as the user question, ignoring the remaining messages; responseChatItemId must be unique within the current chatId. Run detail requires detail, with non-stream results held in responseData and stream results separated by event. The interface does not return actual consumed Token values; when needed, set detail=true and calculate the tokens values in responseData manually. A stored log does not by itself complete a compliance audit; reconciliation, retention, and compliance requirements belong to a separate full business plan.
Constraints at the conversation logs step
A hypothetical drill sample, clearly labelled: an export documentation clerk opens a session for one certificate of origin application. The material text reads: "Certificate of origin application: exporter A, destination country B, commodity C, application date 10 March 2025; commercial invoice amount USD 12,000; packing list 40 cartons; production cost records show local value-added ratio 42%." The session chatId is recorded as H-20250310-01 and the dataId as D-01. The proposed handover request reads: "Transfer this session's run detail and feedback records to the next shift for checking the filing basis." The handover recipient, authorization scope, and effective conditions in this request are not stated and remain pending verification; this does not constitute a completed handover.
Because chatId non-empty pulls the stored session and ignores all but the last message, a handover record keyed to chatId H-20250310-01 must be matched against the same chatId returned by the session list, not against a page-created session. Because responseChatItemId must be unique under its chatId, D-01 cannot be reused for a second response in the same session. Because detail controls whether intermediate values appear, any node record absent from responseData stays a gap rather than evidence of complete retention. Because source=api returns only API-created sessions, page sessions are excluded from that list and must not be counted together.
Configuration and implementation checks
The table below lists documented settings or implementation checks relevant to this function and task. The values are hypothetical drill starting points for comparison only and are not official defaults.
| Configuration item | Official basis or check action | Hypothetical starting point and comparison method |
|---|---|---|
| appId passing | body.appId is recommended in the request body; priority is body.appId, then apiKey-appId, then the apikey-associated appId | Start with the sample appId; compare against the appId in the response to confirm the same application |
| chatId | A non-empty string pulls the session from the database; uniqueness must be ensured and length kept under 250 | Start with H-20250310-01; compare character by character against the chatId returned by the session list |
| responseChatItemId | When passed, it becomes the response message ID stored in the database and must be unique under the current chatId | Start with D-01; compare against the dataId returned by getResData |
| detail | Set detail=true when intermediate values are needed; non-stream results sit in responseData | Start with detail=true; check whether responseData contains the node records for that turn |
| source | When fetching the session list, source=api returns only API-created sessions | Start with source=api; separate page sessions before counting |
| authProxy | Proxy team-member identity requires the team owner to enable it when creating or editing the key; the proxy identity still needs target application and session permissions | Start with not enabled; compare the actual response against the enabled state |
Three common errors
- Treating retrieval or a form as authorization execution. A form collects values; business verification, approval, database writes, and external synchronization each need their stated downstream implementation. In the sample, the "transfer to the next shift" request does not state an authorization boundary, so the existence of a session record does not establish that the handover was approved.
- Treating a similarity score as a permission or entity filter. A relevance score is not a category, entity, or permission filter, and retrieval does not carry authorization, so it cannot be used to exclude unrelated businesses or unauthorized records. In the sample, if similar material from another exporter appears, identity must be checked separately by identifier.
- Assuming unreturned fields were fully retained. The interface documentation states that actual consumed Token values are not returned and that detail plus manual calculation of tokens in responseData is required; business data not returned cannot be assumed fully retained. In the sample, if intermediate values from the production cost records are absent from responseData, record that as a gap.
How to verify the setup
- Input the sample chatId H-20250310-01 and dataId D-01, call the single-conversation run-detail endpoint, and compare the returned dataId against the dataId in the proposed handover record. When they match, that record corresponds to this session; when they differ, record an identifier mismatch and stop the correspondence.
- Input the sample handover request text and compare whether the request states the handover recipient, authorization scope, and effective conditions. When all three are stated and consistent with the material subject, the check condition is met; when any one is missing, record it as pending verification and do not judge the handover complete.
- Input the sample request with detail=true and compare the module records appearing in responseData against the application, invoice, packing list, and cost records listed in the material text, item by item. When each item corresponds, the check condition is met; when a field not listed in the material appears, record it for manual confirmation. For empty-result handling, a paper input of [] can be used to check the downstream design; this does not claim that a fabricated rule search will return empty.
