/**

|
* Librarian service — manages document storage, metadata, and processing records.
|
|
*
|
|
* An AsyncProcessor (NOT FlowProcessor) that:
|
|
* 1. Listens on librarian-request and collection-management-request topics
|
|
* 2. Handles CRUD operations for documents, child documents, processing records
|
|
* 3. Handles collection management (list, update, delete)
|
|
* 4. Stores document files on disk, metadata in-memory (persisted to JSON)
|
|
*
|
|
* Python reference: trustgraph-flow/trustgraph/librarian/service/service.py
