| ### Architectural Role | ### Architectural Role |
| As the stateful layer of the platform, `service-fs` is responsible for data persistence. It is designed to be independent of the analytical software — if the GIS orchestration layer is re-provisioned, the core data assets remain intact within this layer. The clean separation between data persistence and analytical logic is a core design invariant. | As the stateful layer of the platform, `service-fs` is responsible for data persistence.

| In production, `service-fs` is deployed as a low-overhead unikernel. It provides a restricted API for the `service-business` and `service-places` intelligence layers to read raw data and write back processed results, enforcing clean separation between storage and analysis concerns. | In production, `service-fs` is deployed as a low-overhead unikernel.
