## Problem Description
When a user creates Dataset A using the **Tag parser** (for CSV/Excel
files with tag definitions), and then creates Dataset B, the Tag Sets
dropdown in Dataset B's Configuration page cannot display Dataset A.
### Steps to Reproduce
1. Create Dataset A with **Tag** as the chunking method
2. Upload a CSV file to Dataset A to generate tags
3. Create Dataset B
4. Navigate to Dataset B → Configuration → Tag Sets
5. **Expected**: Dataset A should appear in the dropdown
6. **Actual**: The dropdown is empty, Dataset A is not visible

## Root Cause Analysis
After thorough code review, **the original code logic is correct**. The
`chunk_method` field flows properly through the system:
### Data Flow
```mermaid
sequenceDiagram
participant Frontend
participant Pydantic
participant API
participant Database
Note over Frontend,Database: Creating a Tag Dataset
Frontend->>Pydantic: POST {chunk_method: "tag"}
Pydantic->>API: serialization_alias converts<br/>chunk_method → parser_id
API->>Database: INSERT {parser_id: "tag"}
Note over Frontend,Database: Querying Datasets
Frontend->>API: GET /api/v1/datasets
API->>Database: SELECT parser_id, ...
Database-->>API: Returns {parser_id: "tag"}
API->>API: remap_dictionary_keys()<br/>parser_id → chunk_method
API-->>Frontend: {chunk_method: "tag"}
Note over Frontend: Filter: x.chunk_method === 'tag'
Note over Frontend: ✅ Match found!
```
### Field Mapping
**Location**: `api/utils/api_utils.py:657-662`
```python
DEFAULT_KEY_MAP = {
"chunk_num": "chunk_count",
"doc_num": "document_count",
"parser_id": "chunk_method", # Maps DB field to API response
"embd_id": "embedding_model",
}
```
### Frontend Filtering (Already Correct)
**Location**:
`web/src/pages/dataset/dataset-setting/components/tag-item.tsx:24`
```typescript
const knowledgeOptions = knowledgeList
.filter((x) => x.chunk_method === 'tag') // ✅ Correct field
.map((x) => ({...}));
```
---
## Actual Issue
The most likely causes for the "bug" are:
1. **Browser Cache**: Old data cached before proper deployment
2. **Stale Data**: Datasets created before the code was fully deployed
3. **Container Not Restarted**: Changes not applied to running container
---
## Resolution
**No code changes are needed.** The existing code correctly:
1. Accepts `chunk_method` from frontend
2. Converts to `parser_id` via Pydantic serialization_alias
3. Stores in database as `parser_id`
4. Maps back to `chunk_method` in API response
5. Frontend filters by `chunk_method === 'tag'`

### What problem does this PR solve?
When using pagination in the Dataset file list or File Manager,
selecting row N on page 1 would incorrectly cause row N on page 2 (and
subsequent pages) to also appear selected. This is a state pollution
bug.
### Root Cause
TanStack React Table defaults to using array indices (0, 1, 2...) as
`rowSelection` keys. With server-side (manual) pagination, each page's
rows start from index 0, so a selection like `{2: true}` on page 1 also
matches index 2 on every other page.
### Fix
- Added `getRowId: (row) => row.id` to `useReactTable` in both
`DatasetTable` and `FilesTable`, so selection state is keyed by unique
document/file IDs instead of positional indices.
- Updated the `useSelectedIds` helper to support ID-based selection keys
while maintaining backward compatibility with index-based keys.
