Connection Management (75% Coverage) + +| Feature | Status | Implementation | libsql API | Priority | +|---------|--------|---------------|-----------|----------| +| Local database | βœ… | `connect/2` (lib.rs:353) | `Builder::new_local()` | P0 | +| Remote database | βœ… | `connect/2` (lib.rs:402) | `Builder::new_remote()` | P0 | +| Embedded replica | βœ… | `connect/2` (lib.rs:386) | `Builder::new_remote_replica()` | P0 | +| Encryption at rest | βœ… | `connect/2` (lib.rs:393,412) | `Builder::encryption_config()` | P1 | +| Health check | βœ… | `ping/1` (lib.rs:528) | `conn.query("SELECT 1")` | P1 | +| Close connection | βœ… | `close/2` (lib.rs:322) | Registry cleanup | P0 | +| Local replica mode | ❌ | Not implemented | `Builder::new_local_replica()` | P2 | +| Async connect | ❌ | Hidden by runtime | Already async | P3 | + +**Assessment**: Core connection modes are complete.
