What the documents look like
Douyin storefront shelf operations center on product cards and store experience scores. The working materials come from the Douyin store workbench, the Douyin e-commerce learning center, Selected Alliance data, and logistics interfaces. Day-to-day documents include product qualification pages, experience score details, shipping violation appeals, and store announcements. These materials update daily and per order, so a handover must confirm the specific dates and order scope in view.
For this task, the handover concerns operations permissions and access isolation across those materials. The materials themselves do not carry an authorization state. A retrieval relevance score does not function as a category, entity, or permission filter, and retrieval does not perform authorization. A form collects values; it does not execute a business action. Experience score details and shipping violation appeals involve per-order records, so both sides of a handover compare the same subject, the same period, and the same fields.
FastGPT organizes access through members, departments, and groups. Member permissions take highest priority. Department and group permissions combine as a union and rank below member permissions. Resource types include team, app, dataset, and collection. Knowledge base file-level permission is a commercial-edition feature. In the disabled state, a collection's readability matches the knowledge base. In the enabled state, each file or folder generates a permission snapshot, and list, detail, and retrieval recall each authenticate per snapshot. Knowledge base permission always remains the threshold; collection permission cannot bypass it. Retrieval recall filters by the files the current member can read, and this applies only when authentication runs by current member identity. A workflow that preselects a knowledge base without member-identity authentication does not apply file-level filtering. A team administrator does not bypass file-level permission. System root and the team owner are treated as holding all permissions on all files.
Constraints at the access controls step
Several documented conditions shape this handover step. The file-level permission switch is the only entry point that produces collection-level custom permissions. When the switch is off, any write operation configuring a single file's permission is rejected with a prompt to enable it first. Enabling requires the knowledge base administrator (with permission to manage on the knowledge base). Materialization completes synchronously within the request; with many files it takes longer. The switch is set only after materialization succeeds; on mid-way failure the switch stays off and the operation can be re-run because it is idempotent.
Disabling is destructive. It deletes all collaborator configurations for every file and folder under that knowledge base and restores inheritance from the knowledge base. This cannot be rolled back, and the interface requires a second confirmation. Re-enabling after disabling is equivalent to a first enable.
Collaborator configuration uses full-overwrite semantics: the submitted list is the final result. The creator cannot be granted or modified through collaborator configuration, and a submitted collaborator list must include the current creator or it is rejected. Deleting a file or folder is limited to the creator; collaborators with administrator or write permission cannot delete. Bulk deletion filters non-creator items and prompts. Ownership transfer is limited to the creator and may pass to another member of the same team, transferring ownership of subfolders as well. Knowledge base ownership transfer cascades to files and folders under that knowledge base held by the original creator.
Three special identities matter. System root skips file-level parsing and is treated as holding all permissions on all files. The team owner holds all resources in the team and is treated as holding all permissions on all files. A team administrator does not bypass file-level permission; team-level management permission covers only the team's own resources such as member groups and organizations, while knowledge bases and files authenticate by their own collaborator configuration.
Configuration and implementation checks
The following table ties documented settings and implementation checks to this page's sample.
| Configuration item | Documented content | Check on this page |
|---|---|---|
| Member permission | Highest priority, granted directly to an individual | Check the actual member permission record of the handover account |
| Department and group permission | Union, ranked below member permission | Check the department and group membership of the target account |
| Knowledge base file-level permission switch | Disabled inherits the knowledge base; enabled generates snapshots | Confirm the current switch state of the target knowledge base |
| Collection collaborator roles | Read, write, administrator, creator | Check whether the submitted list includes the current creator |
| Retrieval recall authentication condition | Filtered when authenticating by current member identity | Check whether the search entry authenticates by member identity |
| Team administrator boundary | Does not bypass file-level permission | Check the files actually visible to the team administrator account |
Hypothetical paper exercise sample: a Douyin store operations team conducts a handover. Handover account A is a team administrator; receiving account B is an ordinary member. The target knowledge base has file-level permission enabled, and the file "Shipping violation appeal - March 2025" has a collaborator list containing account A (administrator) and account B (read permission). Proposed determination sentence: "Account B can delete this file." Source wording for the check: "Collection collaborator configuration uses full-overwrite semantics; the submitted list is the final result." "Deleting a file or folder is limited to the creator; collaborators with administrator or write permission cannot delete." "A team administrator does not bypass file-level permission." Required fields: account B's role is read permission and is not the creator; the file's creator is account A. Conclusion: account B does not hold delete permission, and the proposed sentence does not hold. For a numeric value, this paper exercise's starting point sets the file-level permission switch to the enabled state. The reason for choosing this value is that the sample explicitly involves single-file collaborator configuration, and the comparison object is the behavioral difference under the disabled state, where permission is inherited from the knowledge base.
Three common errors
- Treating retrieval relevance as permission filtering. Error form: assuming a file with a high similarity score is necessarily visible to the current account. Check: input account B and the target file, compare retrieval recall results against the file-level permission snapshot, and observe whether an unauthorized file appears in the recall list.
- Treating a team administrator as bypassing file-level permission. Error form: assuming account A's team administrator identity grants access to all files. Check: input account A and the target file, compare the team administrator permission description against the file-level permission authentication result, and observe whether the team administrator still requires file-level authorization.
- Treating a form submission as business execution. Error form: assuming submitting a collaborator list completes the permission change. Check: input the collaborator list to be submitted, compare the submitted value against the final effective value, and observe whether the creator is removed by full overwrite.
How to verify the setup
- Input: account B and the collaborator list of the file "Shipping violation appeal - March 2025." Compare: account B's role field against the requirement for the delete operation. Observe: account B's role is read permission, the delete operation is rejected, and the isolation condition is met.
- Input: account A's team administrator identity and the target file. Compare: the team administrator permission description against the file-level permission authentication result. Observe: when account A holds no file-level authorization, the file is not accessible, and the isolation condition is met.
- Input: the collaborator list to be submitted (containing account A and account B). Compare: the submitted list against the current creator field. Observe: when the submitted list includes creator account A, the submission is accepted; when the creator is removed, the submission is rejected. These are paper expectations and were not actually executed.
