# Symphony open-source platform repository goes live

> June 26, 2026 release: QuanuX establishes the canonical Symphony repository as the public home for the modular runtime platform.

*June 26, 2026*

## New features

### Symphony is now public

QuanuX has opened the canonical **Symphony** repository — the public home for the open-source platform that powers the QuanuX runtime. Symphony is structured as a monorepo with modular sovereignty: each module is individually installable, so you can adopt only the pieces you need.

This week's seed publishes the platform's foundational governance and the first runtime module contracts:

* **node-troll** — the node runtime contract.
* **bus-troll** — the bus residency and compatibility layer. First-class and individually installable; required only for deployments that use a managed bus boundary.
* **hotpath-runtime** — the native hot-path runtime substrate. Python is never required for remote native hot-path execution or the administrative spine.

What this means for you:

* You can now track the platform's roadmap and module contracts in the open.
* Deployments that bypass the bus remain fully supported — Symphony does not make bus traversal mandatory.
* Optional isolated Python habitats are only enabled when a module or tool explicitly declares them, keeping the core hot path lean.

No implementation, install scripts, or service files ship in this seed — module contracts only. Runtime payloads will follow in subsequent releases. See [Core Concepts → Architecture](/concepts/architecture) and [Core Concepts → Node Types](/concepts/node-types) for background on how these modules fit into the QuanuX runtime model.
