 - [2026-06-12] Fixed `management/nexus-cli.sh` `ensure_router_reachable` (~line 412): the `nmcli connection up wgs_client` WireGuard fallback dies under WSL (no NetworkManager → "permission denied"). It's now conditional on nmcli + the wgs_client connection existing. **WSL box:** you're a desktop with a direct LAN link to the server, so just make `ssh router` work (Host `router` → 192.168.50.1:9001, user jon, key `id_iWings`, in `~/.ssh/config` — which is NOT synced, set it up there) — then `ncp restore` passes the first check and never hits the VPN fallback.
 - [2026-07-10] Over-engineering purge. Removed dead backend endpoints (`POST /chat`, `/memory/{id}/move[_to]`, `/playbook/run`, `/search`) + their orphaned store methods, and the sync chat wrappers. Deleted the two curses TUIs (`nexus-chat.py`, `nexus-playbook.py`, ~1280 lines) and replaced them with API-backed `ncp` subcommands (`chat`/`memory`/`playbook`/`history` → `management/nexus_api.py`). `controlpanel.py` kept (panel GUI). `/conversations/export` kept (ShareGPT export for future fine-tuning).
 - [2026-07-10] Nuked the ML + scientific/GUI stack from THIS venv only: torch/transformers/accelerate/bitsandbytes/etc + numpy/scipy/pandas/matplotlib/PySide6 + 53 orphans total. **Promethean 16G → 108M.** Requirements files are UNCHANGED — `pip install -r requirements-amd.txt` restores the declared ML stack. Caveat: some installed extras (peft, datasets, mergekit, gguf, hf-xet) were NOT in any requirements file; if the desktop ML work needs them, add them to requirements first. Rollback freeze snapshot was taken pre-purge. **WSL box:** your venv is separate and untouched; run the same `pip uninstall` sweep if you want the space back (nothing in `synapse/` imports any of it — Ollama does inference over HTTP).
+- [2026-07-11] Stood up self-hosted **Gitea** at `git.enderofwings.com` (runs on the router in chroot `/tmp/mnt/GitHead`, Gitea 1.26.4, `DISABLE_SSH=true` so pushes are HTTPS+token). Applied full Nexus/GitNexus branding (custom dir `/var/lib/gitea/custom`). Pushed nexus-core → `enderofwings/NexusOS`.
+- [2026-07-11] **Backup/restore rewritten to use git→Gitea instead of rsync to `router:/tmp/mnt/Wingdrive2/nexus-core`.** `bin/backup.sh` now: dump `memory.db`→`synapse/memory/memory.db.sql` (diff-friendly, so the assistant's memory+history is versioned), `git add -A && commit "backup: <ts>" && push`. `bin/restore.sh` now: clone-or-`git pull`, rebuild the DB from the dump (only if no live DB), then rebuild venv/npm/theme/terminal/panel. `-c|--claude` dry-run kept (git status / incoming diff). Heavies (Promethean, ollama/, models/, node_modules, dist, runtime) still excluded and rebuilt on restore. Auth via `git config credential.helper store` (`~/.git-credentials`, 0600, Gitea PAT). The old `Wingdrive2/nexus-core` rsync folder is being retired — verify a `restore` on a scratch dir before deleting it. **WSL box:** switch your restore path to `git clone/pull https://git.enderofwings.com/enderofwings/NexusOS.git` (make a Gitea account/token; `ssh router` no longer required for backup/restore). Old `ncp restore` rsync path is dead.

+
+# NexusOS
+
+**A local-first AI assistant platform.** Runs entirely on your machine — a
+Python/FastAPI backend, a bundled Ollama instance for inference, a persistent
+memory service, and a React frontend. No external AI provider is called.
+
+</div>
+
+---
+
+## What it is
+
+NexusOS ("Nexus") is a self-hosted assistant you actually own. All inference
+runs through a **locally bundled Ollama** on `localhost`; conversations, facts,
+and settings live in local SQLite. It ships with desktop branding (XFCE theme,
+icons, boot splash) so it can be run as a full assistant environment, not just
+a web app.
+
+- **Chat** — streaming responses from local Ollama models (SSE).
+- **Persistent memory** — a dedicated service auto-extracts durable facts from
+  each exchange and layers them into future prompts.
+- **Playbooks** — ordered YAML system-prompt records; the first is the active
+  persona, the rest are injected as reference context.
+- **Model management** — list, pull, and delete Ollama models from the UI/CLI.
+- **History** — full conversation persistence, search, edit, export.
+
+## Quick start
+
+Requires Python 3, Node, and a GPU is optional (CPU works).
+
+```bash
+# 1. Install deps into the Promethean venv (auto-selects AMD/NVIDIA/CPU)
+./bin/install.sh
+
+# 2. Launch the full stack (memory :8001, backend :8000, frontend :5173)
+./launch_nexus.sh
+```
+
+Python deps are layered: `requirements-base.txt` (GPU-agnostic core) plus one
+overlay — `requirements-amd.txt` (ROCm), `requirements-nvidia.txt` (CUDA), or
+`requirements-wsl.txt` (CPU-only). `bin/install.sh` picks the right one for the
+host.
+
+### Individual services
+
+```bash
+source Promethean/bin/activate
+
+uvicorn synapse.main:sio_app          --host 0.0.0.0 --port 8000 --reload   # backend
+uvicorn synapse.memory.service:app    --host 0.0.0.0 --port 8001 --reload   # memory
+cd interface/web && npm run dev                                             # frontend
+```
+
+## CLI (`ncp`)
+
+Start/stop services and drive the same features as the web UI over the REST API:
+
+```bash
+./management/nexus-cli.sh start        # backend + frontend (--backend|--frontend|--memory)
+./management/nexus-cli.sh stop
+
+ncp chat "<message>"                   # stream a reply
+ncp memory list | add <text> | rm <id>
+ncp playbook list | show <id>          # first playbook (*) = active system prompt
+ncp history [query]                    # recent conversations
+```
+
+## Architecture
+
+| Component | Location | Role |
+|---|---|---|
+| **Synapse** (backend) | `synapse/` | FastAPI app. `/chat/stream`, `/playbooks`, `/memory`, `/models`, `/conversations`, `/settings`, `/ollama`, `/icons`. Assembles the system prompt: active playbook → reference playbooks → memory facts → relevant past snippets. |
+| **Memory service** | `synapse/memory/` | Separate FastAPI app (:8001). `/memories/extract` uses an Ollama prompt to decide what to persist. Shares the SQLite DB with the backend. |
+| **Playbooks** | `synapse/playbooks/` + `data/playbooks/` | Ordered `{id}.yaml` records managed by `PlaybookManager`. |
+| **Ollama** | `ollama/bin/ollama` | Bundled binary; `OllamaManager` handles lifecycle + model selection (Vulkan GPU detection). HTTP API at `127.0.0.1:11434`. |
+| **Frontend** | `interface/web/` | React 19 + Vite. Pages: Chat, Playbooks, History, Models, Memory, Settings. |
+
+### Storage
+
+Most data lives in `synapse/memory/memory.db` (SQLite, WAL) — facts,
+conversations, messages, settings. Playbooks are the exception (YAML files in
+`data/playbooks/`). All paths are defined in `synapse/nexus_config.py`.
+
+## Layout
+
+```
+synapse/          FastAPI backend + memory service + playbook/ollama managers
+interface/web/    React + Vite frontend
+management/       nexus-cli.sh, ncp API client, control panel, desktop theme
+bin/              install, backup/restore, panel + provisioning scripts
+assets/           branding: icons, boot splash, XFCE/GTK theme
+data/playbooks/   active playbook YAML
+```
+
+## Configuration
+
+| Concern | Location |
+|---|---|
+| Ollama host | `OLLAMA_HOST` env (default `http://127.0.0.1:11434`) |
+| Filesystem paths | `synapse/nexus_config.py` |
+| Frontend API base URL | `interface/web/src/config.js` |
+| Python deps | `requirements-base.txt` + amd/nvidia/wsl overlay |
