What the documents look like
Dealer rebate calculation happens after sales close, and its subject matter is policy interpretation and financial treatment rather than stock movement. The working materials come from ERP sales records, dealer remittances, the contract ledger, and the finance system. For operating reports and exception review, four document types matter: the rebate policy, the sales attainment table, the reconciliation statement, and the red-letter invoice used to offset amounts. These materials update monthly or quarterly. The time-consuming steps are reconciling the attainment basis, deducting returned goods, and offsetting against issued invoices.
The database and operations task is narrower than the business calculation itself. It keeps the four document types readable, searchable, and comparable after storage, retrieval, backup, and configuration change. It does not interpret policy and does not decide authorization.
Two features shape this step. First, business source records and the vector retrieval backend have different responsibilities, so each is checked against the actual deployment rather than inferred from a service name. Second, a similarity score reflects textual similarity only. It does not filter by permission, does not isolate one dealer from another, and does not grant business authorization. A retrieval result is evidence of matching text, not of entitlement to view the underlying record.
Constraints at the database operations step
Database connections, cache, vector store, and object storage configuration determine whether report data can be read consistently. Backup creation and actual restore are separate facts and must be verified separately. After any configuration change, the same business sample should be rechecked; a running process does not establish that the data is correct.
Hypothetical drill sample, labelled as such and not drawn from any real customer: a brand finance reviewer checks Dealer A's February 2026 rebate in March 2026. The source text reads: "Dealer A's February 2026 sales attainment table states an attainment rate of 92%; the reconciliation statement states returned goods of RMB 40,000; the rebate policy requires an attainment rate of no less than 90% for the amount to count toward rebate." The draft sentence awaiting judgment reads: "Dealer A's February 2026 rebate has been confirmed and the red-letter invoice offset has been completed." The request is pending verification. Whether a red-letter invoice was issued and whether the rebate was booked are not stated in the source text.
The draft sentence and the source text share the same subject and the same period. The source text states the attainment rate and the returned-goods amount. It does not state invoice issuance or booking status, so the draft's claim of confirmation and completed offset is unsupported and remains pending verification. This is a missing-evidence gap, not a contradiction: the source text does not give an opposing value for the same field.
Configuration and implementation checks
The table lists only implementation items tied to checking this page's documents. The values are starting points for this hypothetical trial, chosen so that observed values can be compared against them. They are not official defaults.
| Configuration item | Hypothetical starting point for this trial | Comparison method and reason |
|---|---|---|
MONGODB_URI | Points to this deployment's primary business database | Confirm the rebate policy and reconciliation statement can be read; do not infer from the name |
MONGODB_LOG_URI | Same as the primary database | Check whether the log store reuses the primary database, so reports and logs are not confused |
REDIS_URL | Points to this deployment's cache | Confirm the cache connects; observe read latency and errors |
DB_MAX_LINK | 10 | Observe connection usage under actual load and compare with the observed peak |
SYNC_INDEX | true | Confirm index maintenance at startup; recheck the same query after a change |
LOG_ENABLE_CONSOLE | true | Keep console logging available for exception review comparison |
Three common errors
- Treating retrieval similarity as permission or entity isolation. Input "Dealer A February 2026 rebate" and retrieval returns similar text only; it does not decide whether the requesting user may view Dealer A's data. Check access control and data ownership separately, and record the gap when evidence is absent.
- Treating backup creation as restore availability. A successful backup job does not show that the February 2026 reconciliation statement can be restored. Perform an actual restore and compare the same business sample; until that is done, restore capability remains unknown.
- Treating a draft sentence under review as a completed fact. The draft says the rebate was confirmed and offset, while the source text states only the attainment rate and returned-goods amount. It does not state red-letter invoice issuance or booking. Mark the draft as pending verification and do not infer authorization or effectiveness.
How to verify the setup
- Input the hypothetical source text and the draft sentence given above. Compare whether the draft shares the same subject, the same period, and the same field as the source. The source text does not state red-letter invoice or booking status, so the draft's "confirmed and completed offset" is unsupported and should be recorded as pending verification.
- Input the same query, "Dealer A February 2026 rebate," once before and once after a configuration change. Compare the returned documents and read latency. When the two results differ, record the difference. Do not assume the first hit is correct or that all relevant documents are recalled.
- Input an empty-result case using the explicit paper input
[]and check how the downstream design handles an empty result. Do not assert that a fictional rule search necessarily returns an empty array; record only the observed return and failure branches.
These checks test the named task: comparing proposed copy against supplied source wording and its limitations. They do not test identity certification, report analysis, or any other task. Where the source text is silent, the gap stays open.
