feat(infra): netcup-vps — podman+k3s, PostgreSQL, Caddy, Prometheus, full ARM64 math stack
...
Swap Docker for Podman + k3s (single-node server).
New services:
- PostgreSQL 16 with JIT + tuned memory (16GB shared_buffers, 48GB cache)
- Caddy reverse proxy (HTTPS for LSP endpoints — needs domain)
- Prometheus node exporter (port 9100)
- NixOS weekly upgrade timer
- Health watchdog (restarts LSP/Ollama if unhealthy)
New packages (ARM64-optimized):
- openblas, blis, lapack — multi-threaded linear algebra
- petsc, slepc — sparse/eigenvalue solvers
- flintqs, pari, gap, singular — number theory / algebra
- symengine — fast C++ symbolic (SymPy backend)
- fftw, suitesparse — FFT and sparse direct solvers
- z3, julia_11 — SMT and JIT numerics
k3s ports: 6443, 2379, 2380
Firewall updated accordingly.

feat(infra): add Tailscale mesh, tmpfs RAM disks, Nix caching, ENE restore
...
- 32GB /tmp and /run/shm tmpfs for fast build scratch
- NixOS cache + Lean community cache substituters
- Tailscale mesh networking (server mode)
- ENE database restore systemd service
- Aggressive parallelism (LAKE_JOBS=16, NIX_BUILD_CORES=16)
- vm.swappiness=10, 1024 hugepages
Packages build passes. System config needs real disk layout from CCP.
