- `meshnet-node` with no args runs interactive setup wizard on first run, then starts directly on subsequent runs using saved config - Wizard auto-detects all GPUs/VRAM, shows curated model list with per-quant VRAM requirements, marks models that exceed available VRAM as incompatible, offers HuggingFace Hub browse as escape hatch - Persistent config saved to ~/.config/meshnet/config.json (0o600) - Live rich dashboard (tokens/sec EMA, VRAM, requests, peers, uptime) with automatic plain-text fallback when stdout is not a TTY (WSL2/SSH/CI) - All wizard values overridable via CLI flags; --reset-config re-runs wizard - `meshnet-node models` lists curated models; `--browse` fetches HF Hub top-20 - `meshnet-node config` prints saved config - `meshnet-node start ...` preserved for backward compatibility - 19 new tests; 97 passed, 1 skipped (no regressions) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
