Bare-metal NixOS 25.11+ flake for server A (standalone AI host, never joins
the dryvist Proxmox cluster). CUDA-first AI stack with disko, sops-nix,
nix-ld, and uv2nix-managed Python environments.
- 22 .nix files: hosts/ai-server-a/{default,disko,networking,hardware-configuration},
modules/{system,ai,secrets,monitoring}/*, lib/checks.nix
- 5 ADRs: disko-vs-manual, cuda-vs-rocm, uv2nix-vs-poetry2nix,
openbao-runtime-secrets, standalone-not-cluster-member
- 5 Mermaid architecture diagrams (.mmd source)
- CI: nix flake check + CodeQL + flake updater + release-please +
mermaid render check (now wired with --no-sandbox puppeteer config)
- Renovate config for auto-PR on nixos-26.05 channel ship
Real disko by-id paths + hardware-configuration.nix land in PR #2 once
the host hardware is being reformatted. Current placeholders document
intent only.

…pkgs module) CI nix flake check failed: nix-ld.dev cannot be enabled at the same time as nix-ld Importing nix-community/nix-ld's nixos module on top of nixpkgs' programs.nix-ld surface (which has shipped in nixpkgs since 23.11) forces the assertion. Drop the flake input + nixosModules.nix-ld import; modules/ai/nix-ld.nix already only touches programs.nix-ld which the nixpkgs-bundled module provides.

Summary
Bare-metal NixOS 25.11+ flake for server A — the dryvist homelab AI host.
Server A is standalone and never joins the Proxmox cluster (B+C+D).
CUDA-first AI stack on top of disko + sops-nix + nix-ld + uv2nix-managed Python.
What's in this PR (skeleton only)
Design constraints encoded
mkEnableOption "ten-gig mesh". 1 GbE only.What lands in PR #2 (later)
Real disko.nix by-id paths + actual hardware-configuration.nix once the host hardware is being reformatted.
Mermaid SVG strategy
Source .mmd files committed; rendered .svg files are produced in CI by the mermaid-render-check workflow with a --no-sandbox puppeteer config to work around the SUID sandbox issue in GitHub Actions Linux runners.
