-Build authentik 2026.2.0 from source via custom Nix derivation, replacing the nixpkgs `pkgs.authentik` dependency. Four components (API client generation, Python backend, web UI, Go server) assembled into a single container image with full supply chain control via forge mirrors.
+Upgrade authentik from 2025.10.1 to 2026.2.0, building core services from source via custom Nix derivations rather than using nixpkgs directly (nixpkgs still provides satellite dependencies like Python, Go, and system libraries). Four components (API client generation, Python backend, web UI, Go server) assembled into a single container image with full supply chain control via forge mirrors.
