                                        - changed file → re-process  
                                        - unchanged → skip

                                        → deadline, doc type, assigned person, etc.

                                        Tools service (openpyxl)

                                        - append new rows / update re-uploaded
                                        - preserve manual edits
                                            │
                                        rclone sync tracker.xlsx back

## Stack

| Service     | Role                          | Language |
|-------------|-------------------------------|----------|
| `server`    | Orchestrator, watcher, state  | Go       |
| `docling`   | Text extraction, OCR          | Python   |
| `ollama`    | LLM structured extraction     | -        |
| `tools`     | Excel read/write, extensible  | Python   |
| `sqlite`    | State tracking (file, no container) | -  |

## Key Rules

- LLM only writes to Excel on **first processing** or **source doc re-upload**
- Mr. Choi can edit any cell freely — edits are preserved
- `_LLM/` directory is excluded from sync and file watching
- Windows watcher uses debounce (15s) and `.last_sync` to avoid feedback loops
