## Ollama Models

None — Ollama not installed. If installed, `qwen3:8b` (5.2 GB) fits the 8 GB VRAM
fully (mirrors DESKTOP-0O8A1RL prose model); qwen3.6 / codestral / qwen3:14b would
split to CPU. GPU acceleration is available via nvidia-open 595.71.05 (CUDA) once the
pending reboot activates the driver. See `.claude/OLLAMA.md`.

## Claude Code Environment

- **Working Directory:** /home/guru/claudetools
- **User:** guru
- **Shell:** zsh (interactive); bash for scripts
- **Git:** Configured for Gitea (git.azcomputerguru.com)
- **Identity:** mike (identity.json configured)
- **Vault:** /home/guru/vault (SOPS + age, decryption verified working)
- **Age key:** `~/.config/sops/age/keys.txt` (mode 600), recipient #1
  `age1qz7ct84m50u06h97artqddkj3c8se2yu4nxu59clq8rhj945jc0s5excpr`
- **Privileges:** guru in `sudo` group; **passwordless sudo enabled**
  (`/etc/sudoers.d/guru-nopasswd`, 2026-05-24) — Claude can run privileged ops.
- **GuruRMM clone:** `/home/guru/gururmm` (canonical server-side path) — builds
  agent + tray locally with cargo; also an enrolled managed agent (id `a73ba38e`,
  systemd `gururmm-agent.service`).

## Network

| Interface | Address |
|-----------|---------|
| Wi-Fi (wlan0) | 10.2.209.225/16 (gw 10.2.0.1) — NOT company LAN |
| Tailscale | 100.75.148.91 (joined 2026-05-24, mike@) |

Field/mobile laptop on wifi; Tailscale now bridges to internal services. pfSense-2
advertises subnet `172.16.0.0/22` into the tailnet and this node runs with
`--accept-routes`, so company LAN host `172.16.3.30` is reachable via `tailscale0`.
Verified 2026-05-24: coord API `172.16.3.30:8001` -> HTTP 200, remote Ollama
`100.92.127.64:11434` -> HTTP 200 (5 models). (D2TESTNAS also advertises
192.168.0.0/24 + 192.168.100.0/24.)

## Notes

- **Strongest raw hardware in the fleet** for AI inference (i9-14900HX, 31 GB RAM,
  RTX 4070 8 GB). NVIDIA driver now installed (see 2026-05-25 note) — GPU/CUDA compute
  available after the pending reboot.
- **Field/mobile laptop.** On wifi off the company LAN, but Tailscale (added
  2026-05-24) bridges to internal services, so coord API/DB and remote Ollama work.
  A local Ollama would still add value for *offline* use (away from any network).
- Onboarding (`LINUX_PC_ONBOARDING.md`) status: /sync OK, vault OK, identity OK,
  Tailscale OK; PENDING — local Ollama (optional), GrepAI, 1Password CLI.
- 2026-05-24: chose Tailscale-only for now; local Ollama + NVIDIA driver deferred.
- 2026-05-24: set up as the **GuruRMM Linux dev/test box** — Rust + GTK build env,
  `gururmm` cloned, enrolled agent runs the new Linux tray (Unix-socket IPC + GTK)
  build. See gururmm PR #13 (`feat/linux-tray-ipc`). The systemd unit was patched
  locally with `RuntimeDirectory=gururmm`; service runs an unsigned local build
  until the PR merges and the pipeline ships a signed agent.
- **2026-05-24: screen lock on timeout INTENTIONALLY DISABLED (user request).**
  xfce4-screensaver `/lock/enabled=false` + `/lock/saver-activation/enabled=false`
  (+ `/lock/sleep-activation=false`); xfce4-power-manager `lock-screen-suspend-hibernate=false`.
  Screen may still blank/screensave on idle but does NOT prompt for a password. Do NOT
  re-enable. Persisted in `~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-screensaver.xml`
  (machine-local, not in the repo).
- **2026-05-24: idle-suspend (sleep) DISABLED on AC *and* battery (user request).**
  xfce4-power-manager `inactivity-on-ac=0`, `inactivity-on-battery=0` (+ sleep-mode actions 0).
  Why both: it was sleeping while plugged in because the ACPI AC-adapter state goes **stale** on
  this Legion + kernel 6.19 (the EC doesn't reliably send AC plug/unplug events, esp. across S3
  resume), so the OS intermittently thought it was on battery and applied the 10-min battery
  suspend. `udevadm trigger --action=change /sys/class/power_supply/ADP0` forces a re-read
  (online flips back to 1). Disabling idle-suspend on both states makes the flaky detection
  harmless. Do NOT re-enable. Persisted in `xfce4-power-manager.xml` (machine-local). Proper
  upstream fix = Lenovo BIOS/EC update.
- **2026-05-25: NVIDIA driver installed — nvidia-open 595.71.05** (open kernel modules + CUDA),
  via the NVIDIA CUDA `debian13` repo (cuda-keyring) since Kali only packages 550 (too old for
  kernel 6.19). DKMS module built + signed for `6.19.14+kali-amd64`; nouveau blacklisted
  (`/etc/modprobe.d/nvidia.conf`) + initramfs rebuilt. **Requires one reboot to activate** (swap
  the dGPU off nouveau). Hybrid graphics: Intel i915 stays the display, NVIDIA dGPU for
  CUDA/offload. Secure Boot off. Verify post-reboot: `nvidia-smi` (expect RTX 4070 Mobile, driver
  595.71.05). Unblocks the local-Ollama-on-GPU option.
