Central config patterns (per README) control database, authentication mode, proxy trust, and feature toggles—operators customize via PHP config files rather than a Django settings.py.
Admin area manages users, permissions, and application parameters. Feature code lives in sections (subnets, tools, etc.) enabling modular maintenance.
Install and upgrade scripts migrate schema versions; long-lived branches exist for maintenance releases per README.
Compared to Source A’s plugin marketplace, Source C favors configuration + built-in modules; deep custom behavior often means forking or wrapping APIs externally.
