## Summary - reuse the dashboard server's initialized `centralCore` for all node-management routes - preserve the legacy fallback only when no shared central authority is provided - never close the server-owned central authority from an individual request - cover node list and registration with regression tests that fail if a route constructs its own `CentralCore` ## Problem With the dashboard running on the PostgreSQL backend, `/api/nodes` and `POST /api/nodes` bypassed the server's initialized PostgreSQL-backed `centralCore` and constructed a separate legacy `CentralCore()`. Reads could hit the wrong registry, while writes failed with a null SQLite handle (`Cannot read properties of null (reading 'prepare')`). The same pattern affected node detail, health, path-mapping, version, plugin-sync, and Docker-config endpoints. ## Verification - targeted regression: 2 tests passed - dashboard typecheck passed - ESLint passed for changed TypeScript files - strict changeset validation passed - dashboard production build passed - `pnpm test:gate` passed against an isolated PostgreSQL 16 cluster: - engine core: 294 tests - PostgreSQL gate: 122 tests - CLI CI-shape: 63 tests ## Changeset Patch release for `@runfusion/fusion`. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved multi-node management by keeping node operations connected to the active PostgreSQL registry. * Updated node listing, registration, configuration, health, version, plugin, path, and Docker configuration routes for more consistent behavior. * Preserved Docker configuration validation and safe response handling. * **Tests** * Added coverage for retrieving and registering nodes through the active registry. * Verified successful node creation responses and handling of optional configuration fields. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Audience
The summary is the only content that appears in end-user release notes by default. Write for Fusion operators — describe behavior, fixes, and what changed. Avoid internal class names, file paths, and implementation detail.
