Runtime package management with security hardening: - pkg-helper: root-privileged daemon for apk install/uninstall via Unix socket - HTTP API: /v1/packages (list/install/uninstall/runtimes), admin role required for writes - Shell deny groups: 15 configurable groups (per-agent overrides via context) - Packages UI: Web page for managing system/pip/npm packages with confirmation dialogs - Docker: privilege separation (root entrypoint → su-exec drop), init for zombie reaping - Security: umask socket creation, persist file validation, deny pattern hardening (Node.js fetch/http, Python from/import, curl localhost, sensitive env vars) - Auth: empty gateway token → admin role (dev/single-user mode)
