DependenciesExplicit [principle] v1.0.0

All dependencies are declared explicitly via a manifest, and isolated at runtime so the app never relies on packages that happen to be installed on the host. This applies to both library deps and system tools — never assume curl, ImageMagick, or a particular Python version is on the box.

Declare every dependency. Isolate at runtime. Never lean on system-wide installs.

Applies To

• Manifest pins exact versions: package.json + lockfile, requirements.txt, go.mod, Gemfile.lock.
• Runtime isolation: virtualenv, node_modules, container image — not the host.
• System tools the app shells out to (ffmpeg, git) are vendored or containerized.
