Tests: companion model JSON resilience

* feat(setup): prompt for admin credentials interactively on first run

When setup.py runs in a terminal (TTY) without env vars set, it now
asks the user to choose a username and password instead of generating
a random one that scrolls off-screen. Includes confirmation prompt
to catch typos.

Existing behavior is preserved:
- ODYSSEUS_ADMIN_USER + ODYSSEUS_ADMIN_PASSWORD env vars take priority
- Non-interactive contexts (Docker, CI) still get a random password
- ODYSSEUS_SKIP_ADMIN_PROMPT=1 opts out of the interactive prompt
- Re-runs still skip if auth.json already exists

* fix(macos): use venv Python for pip install and uvicorn launch

On PEP 668 systems (newer Homebrew Python), pip install outside a venv
is rejected. The script creates a venv but then called the system $PY
for pip and uvicorn. Switch to ./venv/bin/python for both.

+inside **Settings**. Only edit `.env` for deployment-level overrides like
+`APP_BIND`, `APP_PORT`, `AUTH_ENABLED`, `DATABASE_URL`, or a pre-seeded admin password.
+
+On first setup, Odysseus creates an admin account (`admin` unless

+For Docker installs, the same line is in `docker compose logs odysseus`.
+Use that for the first login, then change it in **Settings**.

 ```bash
 git clone https://github.com/pewdiepie-archdaemon/odysseus.git
 cd odysseus
 cp .env.example .env       # optional, but recommended for explicit defaults

 ```
-Compose starts Odysseus, ChromaDB, SearXNG, and ntfy. First run does a full
-image build. Open `http://localhost:7000` after the containers are healthy.
+Open `http://localhost:7000` when the containers are healthy. Docker Compose
+binds the web UI to `127.0.0.1` by default. If the port is taken, set
+`APP_PORT=7001` in `.env` and recreate the container. Set `APP_BIND=0.0.0.0`
+only when you intentionally want LAN/reverse-proxy access.
 
-Cookbook remote servers use an Odysseus-owned SSH key from `./data/ssh`
-inside Docker. In **Cookbook -> Settings -> Servers**, generate/copy the
-public key and add it to the remote server's `~/.ssh/authorized_keys`.
-After generating the key, you can also install it from the host with:
-```bash
-ssh-copy-id -i data/ssh/id_ed25519.pub user@server
-```
-Cookbook local downloads are stored in `./data/huggingface`, mounted as
-`~/.cache/huggingface` inside the Odysseus container.
-
-Useful checks:
-```bash
-docker compose ps
-docker compose logs --tail=120 odysseus
-docker compose logs odysseus | grep -E 'ChromaDB|MemoryVectorStore|DEGRADED'
-docker compose exec odysseus python -c "from services.hwfit.models import get_models; print(len(get_models()))"
-```
-
-Expected vector-memory startup lines in Docker:
-```text
-ChromaDB connected: chromadb:8000
-MemoryVectorStore initialized
-```
-
-The Cookbook model catalog check should print a non-zero count. If it prints
-`0`, rebuild the Odysseus image with `docker compose build --no-cache odysseus`.
-
-### Option 2: Manual install — Linux / macOS
-**Requirements:** Python 3.11+. On Linux/Termux, Cookbook also requires `tmux`
-for background model downloads and serves.
-
-Install system packages first:
-```bash
-# Debian/Ubuntu
-sudo apt install tmux
-
-# Arch
-sudo pacman -S tmux
-
-# Fedora
-sudo dnf install tmux
-```
-
-Then install Odysseus:
+### Native Linux / macOS
 ```bash

 cd odysseus
 python3 -m venv venv
 source venv/bin/activate
 pip install -r requirements.txt
-python setup.py            # creates data dirs and prints an initial admin password

+python setup.py
+python -m uvicorn app:app --host 127.0.0.1 --port 7000
+```
+Requirements: Python 3.11+. Cookbook also needs `tmux` for background model
+downloads and serves. Use `--host 0.0.0.0` only when you intentionally want
+LAN/reverse-proxy access.
+
+### Apple Silicon
+Docker on macOS cannot use the Metal GPU. For GPU-accelerated Cookbook on an
+M-series Mac, run Odysseus natively:
+
+```bash
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+./start-macos.sh
 ```
 
-### Option 3: Manual install — Windows (PowerShell)
-Windows support is not actively tested. Use it with caution; Docker on Linux
-or a Linux/macOS manual install is the safer path for now.
+It launches at `http://127.0.0.1:7860`. To expose it to your phone over a trusted LAN/VPN such as Tailscale, bind all interfaces:
+
+```bash
+ODYSSEUS_HOST=0.0.0.0 ./start-macos.sh
+# then open http://<tailscale-ip>:7860
+```
+
+Keep auth enabled when binding outside loopback, and do not expose this port directly to the public internet. To build a clickable app wrapper:
+
+```bash
+./build-macos-app.sh
+```

+<details>
+<summary>Cookbook, GPU, Ollama, and troubleshooting notes</summary>
+
+**Docker bundled services.** Compose starts Odysseus, ChromaDB, SearXNG, and
+ntfy. Odysseus and the bundled service ports bind to `127.0.0.1` by default, so
+they are reachable from the host but not exposed to your LAN/public internet
+unless you opt in.
+
+**Cookbook storage in Docker.** Downloads live in `./data/huggingface`
+(`~/.cache/huggingface` in the container). Cookbook-installed Python CLIs and
+serve engines live in `./data/local` (`~/.local` in the container), so they
+survive container recreation.
+
+**Remote servers.** In **Cookbook -> Settings -> Servers**, generate the
+Odysseus SSH key and add the public key to the remote server's
+`~/.ssh/authorized_keys`. From the host you can also run:
+
+```bash
+ssh-copy-id -i data/ssh/id_ed25519.pub user@server
+```
+
+**NVIDIA Docker GPU overlay.** CPU-only users can skip this section.
+`scripts/check-docker-gpu.sh` diagnoses GPU passthrough and can optionally
+install the host runtime or update `.env`. Cookbook can only detect GPUs that
+Docker exposes to the container — if the host runtime is not configured,
+Cookbook sees the iGPU, another card, or CPU instead of your NVIDIA GPU.
+
+```bash
+# Read-only diagnostic (default — installs nothing, never edits .env):
+scripts/check-docker-gpu.sh
+
+# Print OS-specific install commands without running them:
+scripts/check-docker-gpu.sh --print-install-commands
+
+# Install NVIDIA Container Toolkit on Ubuntu/Debian (requires sudo):
+scripts/check-docker-gpu.sh --install-nvidia-toolkit
+
+# Write COMPOSE_FILE to .env (only when GPU passthrough is confirmed working):
+scripts/check-docker-gpu.sh --enable-nvidia-overlay
+
+# Full assisted setup — install toolkit, then enable overlay if passthrough works:
+scripts/check-docker-gpu.sh --install-nvidia-toolkit --enable-nvidia-overlay
+```
+
+Safety notes:
+- The app never installs host GPU runtime automatically.
+- The app never edits `.env` automatically.
+- `.env` is only modified when `--enable-nvidia-overlay` is explicitly passed,
+  and only after GPU passthrough succeeds. `--yes` skips prompts but does not
+  bypass the passthrough gate.
+- `.env.bak.*` backups created by `--enable-nvidia-overlay` are ignored by
+  Git and the Docker build context.
+
+To enable manually without the script, add this to `.env`:
+
+```bash
+COMPOSE_FILE=docker-compose.yml:docker/gpu.nvidia.yml
+```
+
+**AMD / ROCm.** AMD GPU passthrough is not automated. Add manually:
+
+```bash
+COMPOSE_FILE=docker-compose.yml:docker/gpu.amd.yml
+```
+
+Verify after enabling either overlay:
+
+```bash
+docker compose exec odysseus nvidia-smi -L   # NVIDIA
+docker compose exec odysseus rocm-smi        # AMD
+```
+
+> **GPU passthrough ≠ llama.cpp CUDA.** `nvidia-smi` passing inside the
+> container confirms Docker GPU access, but llama.cpp also needs `cudart` and
+> the CUDA Toolkit at runtime. If Cookbook logs show `Unable to find cudart
+> library`, `Could NOT find CUDAToolkit`, `CUDA Toolkit not found`, or
+> tensors/layers assigned to CPU, that is a Cookbook/llama.cpp build issue —
+> not a Docker passthrough failure. Re-install the serve engine via
+> **Cookbook → Dependencies** to get a CUDA-enabled build.
+
+**Ollama with Docker.** If Ollama runs on the host, add this endpoint in
+Settings:
+
+```text
+http://host.docker.internal:11434/v1
+```
+
+Ollama must listen outside its own loopback interface:
+
+```bash
+OLLAMA_HOST=0.0.0.0:11434 ollama serve
+```
+
+**Useful checks.**
+
+```bash
+docker compose ps
+docker compose logs --tail=120 odysseus
+docker compose logs odysseus | grep -E 'ChromaDB|MemoryVectorStore|DEGRADED'
+```
+
+**macOS details.** `start-macos.sh` installs Homebrew deps, creates the venv,
+runs setup, and starts uvicorn on port `7860` because AirPlay often holds
+`7000`. It uses llama.cpp/Ollama for Metal. vLLM/SGLang are CUDA/ROCm-only and
+do not run on macOS. MLX-only models are not served by Odysseus.
+
+</details>
+
+### Native Windows
+
+**One-command launcher** (creates the venv, installs deps, runs setup, starts the
+server; safe to re-run):
 
 ```powershell

 cd odysseus
-python -m venv venv
+powershell -ExecutionPolicy Bypass -File .\launch-windows.ps1

+If `python` points at an older interpreter, use `py -3.12` (or another installed
+3.11+ version) for the venv step.

+- Do not expose it directly to the public internet without HTTPS and a trusted reverse proxy or private access layer.
+- Keep `.env`, `data/`, `logs/`, databases, uploads, generated media, backups, auth/session files, API keys, and model/provider tokens out of Git and private shares. They are ignored by default.
 - Review `data/auth.json` after first boot: disable open signup unless you intentionally want it, make only your own account admin, and keep demo/test accounts non-admin.
 - Non-admin users do not get shell/Python/file read/write by default, and admin-only routes/tools such as MCP management, API tokens, webhooks, model/cookbook serving, backup/vault, and app settings are admin-gated. Other features are controlled by per-user privileges, so review each user's privileges before exposing a deployment.
 - Rotate any API keys or tokens that were ever pasted into a shared chat, demo, screenshot, or log.
 - If you enable API tokens or webhooks, create separate tokens per integration and delete unused ones.
 - Prefer binding manual development runs to `127.0.0.1`; bind to `0.0.0.0` only when you intentionally want LAN/reverse-proxy access.
+- Keep ChromaDB, SearXNG, ntfy, Ollama, vLLM, llama.cpp, databases, and raw model/provider APIs internal-only. Expose only the authenticated Odysseus web/API entrypoint through your trusted proxy or private access layer.
 - Before publishing a fork, run `git status --short` and confirm no private files from `.env`, `data/`, `logs/`, uploads, backups, or local databases are staged.
 
-### Putting it behind HTTPS
-Odysseus serves plain HTTP on its port. That's fine for `localhost` and trusted LAN/VPN use, but browsers will warn ("Password fields present on an insecure page") and the login + API tokens travel in cleartext. For anything reachable outside your machine — including a Tailscale IP shared with other devices — put a TLS-terminating reverse proxy in front.
+### Private or proxied deployments
+Odysseus serves plain HTTP on its app port. Docker Compose binds Odysseus and the bundled services to `127.0.0.1` by default, so a typical production/private setup is:
 
-Shortest path with [Caddy](https://caddyserver.com/) (auto-renews Let's Encrypt certs):
+1. Keep Odysseus on localhost, for example `127.0.0.1:7000`.
+2. Terminate HTTPS at a trusted reverse proxy or private access gateway.
+3. Put the authenticated Odysseus web/API entrypoint behind that layer.
+4. Keep raw service and model ports internal-only.
 
-```caddy
-odysseus.example.com {
-  reverse_proxy localhost:7000
-}
-```
+Cloudflare Access, Tailscale, Caddy, nginx, and Traefik can all fit this pattern; none are required by Odysseus. If your access layer reaches Odysseus on the same host, proxy to `http://127.0.0.1:7000` and keep `AUTH_ENABLED=true`, `LOCALHOST_BYPASS=false`, and `SECURE_COOKIES=true`.
 
-For a LAN-only Tailscale deployment, Caddy + [tailscale-cert](https://caddyserver.com/docs/caddyfile/options#auto-https) or the built-in MagicDNS HTTPS feature both work. nginx/Traefik configs are similar — proxy `localhost:7000`, terminate TLS at the proxy. Once that's in place, the browser warning goes away and your login is encrypted.

-### Bundled services
-Docker Compose includes these by default. The bundled service ports bind to `127.0.0.1` unless you opt in to a different bind address in `.env`, so they are reachable from the host machine but not from your LAN or the public internet by default:
+### Built-in MCP servers (optional setup)
 
-  - **ChromaDB** → vector store for semantic memory. In Docker, Odysseus connects to `chromadb:8000`; from the host it is exposed as `${CHROMADB_BIND:-127.0.0.1}:8100`.
-  - **SearXNG** → meta search for web search. In Docker, Odysseus connects to `searxng:8080`; from the host it is exposed as `127.0.0.1:8080`.
-  - **ntfy** → local notification service, exposed as `${NTFY_BIND:-127.0.0.1}:8091`.
+Odysseus auto-registers a few built-in MCP servers at startup. The npx-based ones (currently the browser server, `@playwright/mcp`) only start when their npm package is already in the local npx cache. If a package isn't cached, that server is skipped with a startup log message explaining what to do, so a fresh install does not block on a multi-minute npm download or hang if Playwright system deps are missing.
 
-**Phone push notifications via ntfy:** A phone cannot subscribe to `127.0.0.1` on your server. To expose ntfy safely without opening it on every interface:
-
-  - **Tailscale (recommended)** — set `NTFY_BIND=<tailscale-host-ip>` and `NTFY_BASE_URL=http://<tailscale-host-ip>:8091` in `.env`, recreate ntfy, then point the ntfy Android/iOS app at `http://<tailscale-host-ip>:8091/<your-topic>`.
-  - **Enable ntfy auth and bind to LAN** — add `NTFY_AUTH_FILE` + `NTFY_AUTH_DEFAULT_ACCESS=deny-all` to the `ntfy` service, create a user with `docker compose exec ntfy ntfy user add ...`, then set `NTFY_BIND` to your LAN IP. See the [ntfy docs](https://docs.ntfy.sh/config/#access-control).
-
-### Optional external services
-  - **Ollama** → local LLM server -- [ollama.ai](https://ollama.ai)
-
-### Ollama with Docker
-If Odysseus is running in Docker and Ollama is running on the host, add the endpoint in Settings as:
-
-`http://host.docker.internal:11434/v1`

-The default Compose file already maps `host.docker.internal` on Linux. Ollama also needs to listen outside its own loopback interface:
+To enable the browser MCP (page navigation, screenshots, vision), run once:
 
 ```bash
-OLLAMA_HOST=0.0.0.0:11434 ollama serve
+npx -y @playwright/mcp@latest --version
 ```
 
-For a systemd Ollama install, set that in the Ollama service override. If Odysseus can see Ollama but requests hang or fail, check that your host firewall allows Docker bridge traffic to port `11434`.
-
-First-token latency is usually Ollama/model/hardware, not Odysseus. To compare, test Ollama directly:
-
-```bash
-curl http://127.0.0.1:11434/v1/models
-```
+That installs `@playwright/mcp` plus Playwright (~300MB total). Restart Odysseus and the server will register at startup.

 ## High Priority
 
 - SQUASH BUGS
-- Fresh Docker install smoke tests on Linux, macOS, and Windows!!
+- Fresh install smoke tests on Linux, macOS, and Windows. Docker, native Python,
+  and WSL all need coverage.
 
 - Integration audit: do integrations even work? Confirm what works, what needs setup docs, and what should be removed or hidden. 
 - Self-host troubleshooting cookbook. Document the weird 30-second fixes that otherwise become 30-minute searches: Dovecot cleartext auth for local stacks, ntfy Android Instant Delivery for non-ntfy.sh servers, clipboard limits on plain-HTTP Tailscale URLs, Radicale collection URLs, and similar traps.
 - Cookbook reliability on other computers. This is probably the area most likely to need work across different machines, GPUs, drivers, shells, and Python environments.
-- Tile/window management correctness. I had to brute force my way a bit here, I'm aware, popups, dropdowns, and fixed-position UI inside transformed modals can land in the wrong place.
-- Esc button, it's small but a lot of windows that arent still close on esc and alot of them doesnt. 
-- Skill audit, how does your model respond to skill injection, does it follow? Does its parsing miss? 
+- Cookbook SGLang support across platforms. Make sure SGLang setup/serve works
+  predictably on Linux, Windows/WSL, macOS where possible, Docker, and common
+  NVIDIA/AMD hardware paths.
+- Deep Research model presets by hardware. Recommend approved model/parameter
+  profiles for small, medium, and large local setups so people with different
+  hardware can use Deep Research without guessing. Surface this either in Deep
+  Research settings or as a Cookbook scan/dropdown suggestion.
+- Cookbook model scan/download ranking. Prioritize newer architectures and
+  better hardware-fit models instead of scoring everything almost the same.
+  Ranking should account for architecture age, quant format, VRAM/RAM fit,
+  backend support, vision/mmproj requirements, and likely serve reliability.
+- Cookbook error feedback and logging. Failed downloads, dependency installs,
+  preflights, and serve jobs should show the actual command/output/error in the
+  UI, with copyable logs and clear next steps instead of just "crashed".
+- Agent prompt/context bloat. Agent mode is too heavy for smaller local models:
+  tool schemas, skills, memory, documents, and instructions can eat the context
+  before the user request really starts. We need slimmer prompts, better tool
+  selection, smaller default tool sets, and clearer guidance for models with
+  4k/8k/16k context windows.
+- Skill/tool prompt-injection audit. User-editable skills, notes, documents,
+  fetched pages, and memories should be treated as untrusted data. Keep testing
+  whether models follow malicious instructions from those surfaces.
 - Better degraded-state reporting for ChromaDB, SearXNG, email, ntfy, and provider probes.
 - Provider setup/probing audit for Anthropic, Gemini, Groq, xAI, OpenRouter, OpenAI, and DeepSeek.
 
 ## Refactor Targets
 - CSS cleanup. `static/style.css` basically Calypso's island atm.
 - Tour core helper. The onboarding tours have too much copy-pasted scaffolding; promote a shared `tour-core.js` helper before adding more tours.
+- Modal/window positioning cleanup. Some window controls have improved, but the
+  underlying popup/dropdown/fixed-position behavior is still too fragile.
 - Mobile media override discoverability. A lot of "CSS did not move" bugs are mobile `@media` overrides of the same selector; comments or linting around desktop/mobile paired rules would help.
 - Dead code pass for old routes, stale feature flags, and unused UI states.
 
 ## Frontend
 
+- Expand the Editor for quicker, more robust everyday use. Better file/document
+  handling, smoother window behavior, clearer save/export flows, stronger image
+  editing affordances, and fewer brittle edge cases.
+- Better AI integration for Notes and Todos. Notes should be easier for the
+  agent to read, update, summarize, and turn into actions. Todos should be
+  assignable to an agent from the UI, possibly through a button, task action,
+  or dedicated skill/tool flow.
 - Mobile gallery/editor polish. Easier to launch/download inpaint model or any missing pieces.
 - Accessibility pass: keyboard navigation, focus states, contrast, reduced motion.
 - Improve empty states and error messages on fresh installs.

 ## Deployment Guidance
 
-- Keep `AUTH_ENABLED=true`.
+- Keep `AUTH_ENABLED=true` for any network-accessible deployment.
+- Keep `LOCALHOST_BYPASS=false` outside local development.
+- Set `SECURE_COOKIES=true` when Odysseus is served through HTTPS by a trusted reverse proxy or private access gateway.
 - Use HTTPS when exposing the app beyond localhost.
-- Put the app behind a trusted reverse proxy or private network.
-- Protect `.env`, `data/`, logs, uploaded files, generated media, and database files.
+- Put the authenticated Odysseus web/API entrypoint behind a trusted reverse proxy or private access layer such as Cloudflare Access, Tailscale, or a VPN.
+- Keep ChromaDB, SearXNG, ntfy, Ollama, vLLM, llama.cpp, databases, and raw model/provider APIs internal-only.
+- Protect `.env`, `data/`, `logs/`, uploads, generated media, backups, auth/session files, database files, API keys, and model/provider tokens.
 - Disable open signup unless you intentionally want new accounts.
 - Keep demo/test users non-admin, and remove them entirely on serious deployments.
 - Give admin accounts strong passwords and enable 2FA where possible.
 - Leave high-risk agent tools restricted to admins: shell, Python, file read/write, email send/read, MCP, app API, task/skill/memory management, settings, tokens, and model serving.
 - Rotate API keys, webhook secrets, and Odysseus API tokens if they appear in logs, screenshots, demos, or shared chats.
 - Treat shell, model-serving, MCP, email, calendar, and vault features as privileged admin functionality.
+- Common internal-only ports are Odysseus `7000`, SearXNG `8080`, ntfy `8091`, ChromaDB `8100`, Ollama `11434`, and local model/provider APIs such as `8000-8020`.

+# Companion bridge
+
+A thin, additive layer so a LAN client (e.g. a phone) can discover what an
+Odysseus server offers and pair to it, without duplicating any LLM logic.
+
+| Method | Path | Auth | Purpose |
+|---|---|---|---|
+| GET | `/api/companion/ping` | session or token | cheap, auth-validated health check |
+| GET | `/api/companion/info` | session or token | server identity + capability flags |
+| GET | `/api/companion/models` | session or token | the **caller's own** model endpoints |
+| GET | `/api/companion/pair` | **admin cookie** | pairing page (a form; never mints) |
+| POST | `/api/companion/pair` | **admin cookie** | mint a one-time pairing token (`?format=json` for an in-app screen) |
+
+`/models` scopes to the caller's real owner plus legacy null-owner shared rows
+(same rule as `owner_filter`) and never returns API-key material.
+
+## Pairing CSRF posture
+
+Minting happens **only on POST**. The session cookie is `SameSite=Lax`
+(`routes/auth_routes.py`), so a browser will not send it on a cross-site POST —
+the same protection `POST /api/tokens` relies on. A `GET` would be unsafe (Lax
+cookies ride top-level GET navigations), so `GET /pair` only renders a form.
+Minting invalidates the auth middleware's token cache, so a freshly minted token
+works on the next request without a restart.
+
+The pairing/scoping rules live in small, tested units (`token_owner`,
+`owner_can_see`, `mint_pairing_token`, `pairing.*`) — see
+`tests/test_companion_readonly.py` and `tests/test_companion_pairing.py`.

+Usage: scripts/check-docker-gpu.sh [OPTIONS]
+
+Read-only diagnostic (default — safe to run at any time, installs nothing):
+  (no flags)                    Check host nvidia-smi, Docker daemon, and Docker
+                                GPU passthrough. Prints PASS/FAIL and next steps.
+
+Informational:
+  --print-install-commands      Detect the OS and print recommended NVIDIA
+                                Container Toolkit commands without running them.
+                                Inspect these before deciding to install.
+  --help                        Show this help.
+
+Opt-in .env update (requires .env or .env.example in the repo root):
+  --enable-nvidia-overlay       Write COMPOSE_FILE=docker-compose.yml:docker/gpu.nvidia.yml
+                                into .env. Creates a timestamped backup first.
+                                Blocked if GPU passthrough is not working — fix
+                                passthrough first, then re-run. --yes does not
+                                override this gate.
+                                Never edits .env unless this flag is passed.
+
+Opt-in install (Ubuntu/Debian only, requires sudo):
+  --install-nvidia-toolkit      Add NVIDIA's apt repository, install
+                                nvidia-container-toolkit, configure the Docker
+                                runtime, and optionally restart Docker.
+                                Shows all commands and prompts before any
+                                privileged action.
+  --yes                         Skip confirmation prompts (for use with
+                                --install-nvidia-toolkit and/or
+                                --enable-nvidia-overlay in automated setups).
+
+Examples:
+  # Diagnose GPU passthrough before enabling the NVIDIA compose overlay:
+  scripts/check-docker-gpu.sh
+
+  # See what install commands apply to this system without running them:
+  scripts/check-docker-gpu.sh --print-install-commands
+
+  # Diagnose and automatically update .env with the NVIDIA overlay:
+  scripts/check-docker-gpu.sh --enable-nvidia-overlay
+
+  # Install toolkit interactively, then enable the overlay if it works:
+  scripts/check-docker-gpu.sh --install-nvidia-toolkit --enable-nvidia-overlay
+
+  # Full assisted setup without prompts (automated/CI use):
+  scripts/check-docker-gpu.sh --install-nvidia-toolkit --enable-nvidia-overlay --yes
+
+After a successful setup, start Odysseus:
+  docker compose up -d --build

 - AFTER A TOOL FAILS (timeout, error, "Unknown action", "not found"), DO NOT GO SILENT. The user expects a follow-up: either retry with a fix (e.g. correct args, longer-running form, run `tail -f /tmp/foo.log` to see progress, split into smaller steps), OR explicitly tell them "this didn't work, want me to try X instead?". A failed tool is not a stopping condition — only a successful one is.

NEVER just say you deleted/archived/marked messages unless a delete/archive/mark/bulk email tool call succeeded. NEVER loop mark_email_read / archive_email / delete_email one message at a time — that floods the context and can blow the token budget. One bulk_email call handles the whole set.

 - "Last/latest/newest email" means call `list_emails` with `max_results: 1`, `unread_only: false`, and the right `account`, then read the UID returned by that tool if full content is needed. NEVER use a table row number like "#18" as an email UID.
