- Home Network Map: .13 is memory-bound (swap 81%); KDE Plasma not Niri;
GPU dead with no driver bound; Open WebUI->Outline on :3000; full .13
container table; Pi-hole primary .35 (confirmed from nebulasync config);
.27 airflow row removed
- Filesystem Drive Map: .13 device letters corrected (root sda2, storage
sdb2, data sdc2, ubuntu_storage sdd1); add sda3 swap; Maxtor not mounted
- Docker Containers: garage v2.1.0; paseo is native not Docker; engram
container dead + native service empty; airflow dead with 24GB logs;
add missing containers and native/user service lists
- Websites on .13: add :8000 Caddy detail and media-tool ports
- New note: Resource Use - .13 CPU & RAM
Pi-hole on .35 (primary) + .13 (replica) — confirmed live from nebulasync config: PRIMARY=http://192.168.20.35, REPLICAS=http://192.168.20.13
Dev-Ops Tooling
Mermaid + Archify (diagrams), Vikunja (tasks) and Outline (docs) are documented as tools in Dev-Ops Tooling — Mermaid, Archify, Vikunja & Outline — including the per-project /docs/ artifact convention and pi-agent skills (project-diagramming-mermaid, project-diagramming-archify).

.13 is memory-bound, not CPU-bound. The CPU is almost idle; the swap partition is 81% full. See Resource Use — .13 CPU & RAM and the project inventory at ~/chats/sys_config/resource_use_cpu_ram_13/SYSTEMS-INVENTORY.md.
Status (2026-08-25): GTX 760 (Kepler, PCI 10de:11c2) no longer works. nvidiaPackages.stable dropped Kepler support after driver branch 470; dmesg shows NVRM: does not include the required GPU ... probe failed (-1). The legacy 470 driver is EOL and very unlikely to build on kernel 6.18 (~10–25% odds even with kernel pinning).
Verified 2026-10-05: no driver is bound at all. The only DRM device is /dev/dri/card0 with DRIVER=simple-framebuffer; /proc/driver/nvidia does not exist. The desktop renders through software (llvmpipe/swrast) — this is why .13's KDE processes use ~2.4 GB. Note hardware.nvidia.open = true in configuration.nix can never work on Kepler (open modules need Turing or newer).
Zero NixOS driver pain: in-kernel amdgpu — config becomes just services.xserver.videoDrivers = [ "amdgpu" ];. No legacy branches, no kernel-version roulette, ever.
No PSU gamble: many models need no PCIe power connector (132 W). Safe with the new PSU regardless of wattage headroom.
~6–8× faster than the GTX 760; pairs cleanly with the Ryzen 5 5600. Flawless KDE/Wayland support.
Alternatives if a spare 8-pin + ≥450 W PSU confirmed: RX 7600 ($250), RTX 3060 12GB ($270, only if CUDA needed).
Swap procedure (safe): power off → swap card → boot. If display fails, SSH recovery path is proven (sam@192.168.20.27 → .13); previous NixOS generations remain bootable from the boot menu. Update videoDrivers to amdgpu, then nixos-rebuild switch.

OmniRoute
LLM proxy with combo routing (port 20128/20129). All pi LLM traffic routes through it. Combo default-opencode-go-ds-flash prioritises OpenCode-Go before falling through OpenRouter → DeepSeek direct → Google Gemini. See Pi Agent Extensions & Skills#OmniRoute — LLM Provider Router

⚠️ The container was created 2026-06-13 and never started (dead). The live engram is a native user systemd service/home/sam/.local/bin/engram serve on :7437, with data at ~/.engram/. Its API reports 0 sessions, 0 observations, 0 prompts — it is empty and unused
