Regional shard layer
Feature-gated prototype; separate from the durable production reference.
Prototype / draft — separate from production registry operations.
Status: prototype / draft.
Design scope
Regional shards are a proposed partitioning and locality layer. The topology and affinity modules model assignments and routing. They do not replace the default PostgreSQL store or establish an automatically deployed regional service.
Explore the implementation
The mars-shard library reference lists every module and source boundary. Feature flags and local types are implementation evidence, not live network evidence.
Use the current registry
For production integration, start with HTTP discovery, PostgreSQL operations, and the generated API contract.
Source authority
This page describes the checked-in implementation, not the availability of a public registry. MARS-S is a feature-gated prototype; it is not the production storage topology.
