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.

-### 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.

 ## 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.

+
+`/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`.

+A thin, additive layer so a LAN client (e.g. a phone) can discover what a server
+offers and pair to it, without duplicating any LLM logic.
+
+Auth is enforced globally by AuthMiddleware (app.py), so reaching a handler here
+means the caller is authenticated by either a cookie session or a Bearer `ody_`
+API token. The read endpoints (ping/info/models) accept either; the pairing
+endpoints are admin-cookie only.
+
+Pairing CSRF posture: minting happens ONLY on POST. The session cookie is
+SameSite=Lax (routes/auth_routes.py), which a browser does not send on a
+cross-site POST, so an admin's cookie can't be used by a malicious page to mint
+a token -- the same protection the existing POST /api/tokens relies on. Minting
+on a GET would be unsafe (Lax cookies ride top-level GET navigations), so GET

+
+Informational:
+  --print-install-commands      Detect the OS and print recommended NVIDIA
+                                Container Toolkit commands without running them.
+                                Inspect these before deciding to install.

+                                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.

+// Accessibility enhancements for keyboard + screen-reader users.
+//
+// Several primary controls in Odysseus are authored as click-only <div>s
+// (most notably the whole sidebar navigation: New Chat, Search, Brain,
+// Calendar, Compare, Cookbook, Deep Research, Gallery, Library, Notes,
+// Tasks, Theme, plus the account row). <div>s are not in the tab order and
+// are not announced as buttons, so keyboard and screen-reader users cannot
+// reach or operate them.
+//
+// This module enhances those rows in place — making them focusable
+// (tabindex=0), announcing them as buttons when it's safe to do so, and
+// activating them with Enter / Space — without changing how they look or
+// how they behave for mouse users. The visible focus ring already exists in
+// style.css (`.list-item:focus-visible`); it simply never fired because the
+// rows were never focusable.
