Understanding the system software architecture
Companion consists of the following components, termed modules:
Additionally, the controller includes the following FPGAs, which cannot be updated by the software manager:
In the Aegis and other systems that must open the battery door to access a holographic display, the hatch controller is also responsible for activating screen projection. For other systems with holographic screens, such as the Yutani Springs XSU and the DAX/3, this is performed by the illumination controller.

In the event that one of these modules misbehaves, it may be possible to fix the issue by resetting the module through the manage > modules menu. Be aware that resetting modules often causes information and configuration loss.
Every standard software package installed into user memory includes a package manifest, which can be recognized by the tilde (~) prefixed onto the package’s exact name. This manifest defines the files that the package is responsible for. When a package is uninstalled, the disk driver (songbird) will use this manifest file to determine what to remove. Packages are completely removed prior to update.

Packages
Every standard software package installed into user memory includes a package manifest, which can be recognized by the tilde (~) prefixed onto the package’s exact name. This manifest defines the files that the package is responsible for. When a package is uninstalled, the disk driver (songbird) will use this manifest file to determine what to remove. Packages are completely removed prior to update.
