09 Architecture · Launcher

The control hub.

The Launcher is LIVEX's orchestration layer. It does not simulate, analyse or render: it coordinates SYNE, ECHOS and PRISM from a single interface.

In development Target version 0.1.0 · Avalonia desktop application

In development: the main interface flows are present in the repository; variants and full validation remain open. No public distribution to date.

9.1 Role

Coordinate, without deciding in place of components.

The Launcher allows you to drive, combine, monitor and archive work carried out with SYNE, ECHOS and PRISM, from a single interface and a single data format. It contains neither the simulation logic (SYNE), nor the analysis logic (ECHOS), nor the rendering logic (PRISM): it only coordinates them.

SYNE remains the single engine. ECHOS and PRISM are two ways of using that engine, of equal weight and selectable: ECHOS for analysis, reproducibility and calibration; PRISM for real-time representation. The Launcher allows them to be activated separately or together, without introducing a hierarchy between them.

The Launcher is a component of equal weight to the other three: it has its own data model and invariants, and remains independent. Removing it must not render any other component unusable.

9.2 What it enables

One session, from launch to archive.

Drive

Start, combine and stop components; check their status and health.

Organise

Group runs into campaigns, in a single package format (.livexp).

Observe

Display measurements produced by ECHOS, without recalculating them (display does not modify the world).

Contextualise

Open a PRISM rendering session when available, in parallel with analysis.

Capture — experiences and campaigns management in the Launcher — Capture — experiences and campaigns management (work-in-progress).

Capture — PRISM rendering view opened from the Launcher — Capture — access to a PRISM rendering view from the Launcher (work-in-progress).

These visuals reflect a work-in-progress version from the repository, not a published public version. Milestone status is recorded in the roadmap.

9.3 Platforms and launch

Windows and Linux, locally.

Element	Value
Usage	Native desktop application (not a web interface)
Technology	.NET (C#), MVVM architecture, cross-platform Avalonia UI
V0.2 platforms	Windows and Linux
Installer	At specification stage — not delivered

Planned launch from terminal:

livex-launcher            # open workspace
livex-launcher --check    # check environment, no UI
livex-launcher --package <path.livexp>   # open a campaign

Until a release exists, installation and startup from source are described in theinstallation guide.
