fix(caldav): include owner in calendar ID hash to prevent PK collision (#2765)

_stable_cal_id hashed only the remote URL, producing the same calendar
ID for all users syncing the same CalDAV endpoint. The second user would
get an IntegrityError on the primary key. Now includes owner in the
hash so each user gets a distinct calendar row.

+## Summary
+
+<!-- One paragraph: what changed and why. "Fixed bug" and "Added feature" are not summaries. -->
+
+## Target branch
+
+- [ ] This PR targets **`dev`**, not `main`. All PRs land in `dev`; `main` is curated by the maintainer at each release. If your PR is on `main` by accident, click "Edit" on this PR and change the base.
+
+## Linked Issue

+
+Fixes #
+
+## Type of Change
+
+- [ ] Bug fix (non-breaking — fixes a confirmed issue)
+- [ ] New feature (non-breaking — adds new behaviour)
+- [ ] Breaking change (changes or removes existing behaviour)
+- [ ] Refactor / cleanup (behaviour unchanged)
+- [ ] Documentation only
+- [ ] CI / tooling / configuration
+
+## Checklist
+
+- [ ] I searched [open issues](https://github.com/pewdiepie-archdaemon/odysseus/issues) and [open PRs](https://github.com/pewdiepie-archdaemon/odysseus/pulls) — this is not a duplicate.
+- [ ] This PR targets `dev`
+- [ ] My changes are limited to the scope described above — no unrelated refactors or whitespace changes mixed in.
+- [ ] I actually ran the app (`docker compose up` or `uvicorn app:app`) and verified the change works end-to-end. Type-checks and unit tests are not enough.
+
+## How to Test
+
+<!-- Step-by-step instructions a reviewer can follow to verify this works.
+     Do not leave this empty — a PR without test steps will be sent back. -->
+

+
+## Visual / UI changes — REQUIRED if you touched anything that renders
+
+**Anything that changes what the UI looks like — buttons, icons, padding, colors, fonts, spacing, layout, CSS, HTML, SVG, or any `static/js/` module that draws to the DOM — needs all of the following. PRs that change rendering without these WILL be closed.**
+
+- [ ] **Screenshot or short clip** of the change in the running app, attached below. Mobile screenshot too if the change affects mobile.
+- [ ] **Style match**: the change uses Odysseus's existing visual language. Specifically:
+  - Reuse existing CSS variables (`--red`, `--fg`, `--bg`, `--card`, `--border`, etc.) — do not introduce new color values, font sizes, or spacing units.
+  - Reuse existing button/input/card/border classes. Don't invent parallel styling.
+  - **No Unicode emoji in UI or code.** Use inline SVG (matching the monochrome icon style already in `static/index.html`) or plain text.
+  - Monospaced font (`Fira Code`) for primary UI text. Don't override.
+  - Dark theme is the default; any light-mode work must be wired through the existing theme system, not hard-coded.
+- [ ] **No new component patterns.** If a similar widget already exists in the app, extend it instead of writing a parallel one.
+- [ ] **I am not an LLM agent submitting a bulk PR.** If you are, please open an issue describing the problem first — bulk auto-generated PRs that don't match the project's visual style are closed on sight, even when the underlying fix is correct.

+# Contributing to Odysseus
+
+Thanks for helping. The project is moving quickly, so the best contributions are focused, easy to review, and easy to test.
+
+## Branch model
+
+Odysseus has two branches:
+
+- **`dev`** — where all PRs land. Things can be in flux here; the merge button gets used freely.
+- **`main`** — what users run. Curated and tested by the maintainer. Fast-forwarded to a stable `dev` commit at each release.
+
+**Open your PR against `dev`, not `main`.** The GitHub "base" dropdown defaults to `dev`. If you opened a PR against `main` by accident, click "Edit" on the PR and change the base — no rebase needed.
+
+End-users cloning the repo will land on `dev` by default. To run the curated/stable version: `git checkout main` after clone.
+
+## Before You Start
+
+- Search existing issues and pull requests before opening a new one.
+- Prefer one bug fix or feature per pull request.
+- Avoid broad rewrites, formatting-only changes, or moving many files unless the issue is specifically about structure.
+- If you want to work on a large feature, open an issue first and describe the approach.
+
+## Setup
+
+Docker is the recommended path for normal testing:
+
+```bash
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+cp .env.example .env
+docker compose up -d --build
+```
+
+Manual development uses Python 3.11+:
+
+```bash
+python3 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+python -m uvicorn app:app --host 0.0.0.0 --port 7000
+```
+
+Windows is not actively tested. Docker on Linux or a Linux/macOS manual install is the safer path for now.
+
+## Running Checks
+
+Run the smallest relevant checks for your change:
+
+```bash
+python -m pytest
+python -m py_compile app.py routes/*.py src/*.py
+node --check static/js/<file-you-changed>.js
+```
+
+For Docker-related changes:
+
+```bash
+docker compose config
+docker compose up -d --build
+docker compose logs --tail=120 odysseus
+```
+
+Mention what you ran in the pull request description. If you could not run a check, say so.
+
+## Pull Requests
+
+Good pull requests usually include:
+
+- A short explanation of the bug or feature.
+- The files or areas changed.
+- Manual test steps or automated test results from running the actual app, not just the test suite.
+- Screenshots or short recordings for UI changes.
+- Links to related issues, for example `Fixes #123`.
+
+Please keep PRs small. Large PRs that mix unrelated cleanup, formatting, refactors, and behavior changes are much harder to review.
+
+> **Auto-generated PRs.** If you are running an LLM agent (Devin, Cursor, OpenHands, Claude Code, etc.) against this repo: please open an issue describing the problem first instead of opening a PR directly. Bulk agent-generated PRs that don't match the project's visual style or contribution format will be closed without review, even when the underlying fix is correct.
+
+## Style and visual changes
+
+Odysseus has an intentional visual style. PRs that ignore it will be closed without merge, no matter how correct the underlying code is.
+
+Before submitting any change that affects what the app looks like — buttons, icons, fonts, colors, spacing, layout, CSS, HTML, SVG, or any `static/js/` module that draws to the DOM — please:
+
+1. **Run the app locally** and view the change in a browser. Type-checks and unit tests are not enough.
+2. **Attach a screenshot or short clip** of the change in the running app. Add a mobile screenshot too if the change affects mobile.
+3. **Match the existing visual language.** Specifically:
+   - Reuse existing CSS variables (`--red`, `--fg`, `--bg`, `--card`, `--border`, …). Do not introduce new color values, font sizes, or spacing units.
+   - Reuse existing button, input, card, and border classes. Don't invent parallel styling for similar widgets.
+   - **No Unicode emoji in UI or code.** Use inline SVG (matching the monochrome icon style already in `static/index.html`) or plain text.
+   - Monospaced font (`Fira Code`) for primary UI text. Don't override.
+   - Dark theme is the default; any light-mode work goes through the existing theme system, not hard-coded.
+4. **Don't add parallel components.** If a similar widget already exists in the app, extend it instead of writing a new one.
+
+If you are unsure whether a change is "visual," it is. Default to attaching a screenshot.
+
+## Issue Reports
+
+For bugs, include:
+
+- Install method: Docker, manual Python, WSL, etc.
+- OS, browser, and device if relevant.
+- Exact steps to reproduce.
+- Expected behavior and actual behavior.
+- Logs, screenshots, or terminal output.
+
+For model-serving issues, include:
+
+- Backend: Ollama, vLLM, SGLang, llama.cpp, LM Studio, etc.
+- Model name.
+- GPU/CPU and operating system.
+- Cookbook task logs or server logs.
+
+Issues with only "help", "does not work", or a screenshot without context may be closed as not actionable.
+
+## Security
+
+Do not post secrets, API keys, private logs, personal documents, or public IPs in issues or pull requests.
+
+For security reports, follow [SECURITY.md](SECURITY.md).

 A self-hosted AI workspace -- meant to be the self-hosted version of the UI experience you get from ChatGPT and Claude. But with more jank and fun. Running on your own hardware, with your own data -- local-first, privacy-first, and no trojan.
 
-> Fun fact: a chunk of Odysseus was built **from a phone** -- mobile shells (Termux), the PWA install, and on-device agents. So "works on mobile" isn't an afterthought, it's where a lot of it actually happened.

 ## Quick Start
 
-Defaults work out of the box — clone, run, configure inside the app.
-Open the **Settings** panel after first login to point Odysseus at your LLM
-server, search provider, email account, etc. Only touch `.env` if you need
-to override deployment-level things like `AUTH_ENABLED`, `DATABASE_URL`,
-or pre-seed `ODYSSEUS_ADMIN_PASSWORD` (otherwise an initial password is
-generated and printed on first boot).
+Defaults work out of the box: clone, run, then configure models/search/email
+inside **Settings**. Only edit `.env` for deployment-level overrides like
+`APP_BIND`, `APP_PORT`, `AUTH_ENABLED`, `DATABASE_URL`, or a pre-seeded admin password.
 
-### Option 1: Docker (recommended)
+On first setup, Odysseus creates an admin account (`admin` unless
+`ODYSSEUS_ADMIN_USER` is set) and prints a temporary password in the terminal.
+For Docker installs, the same line is in `docker compose logs odysseus`.
+Use that for the first login, then change it in **Settings**.
+
+Contributing? See [CONTRIBUTING.md](CONTRIBUTING.md) for setup, testing, and
+pull request guidelines.
+
+### Docker (recommended)
 ```bash
-git clone <your-odysseus-repo-url>
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
 cd odysseus
 cp .env.example .env       # optional, but recommended for explicit defaults
 docker compose up -d --build
 ```
-Compose starts Odysseus, ChromaDB, SearXNG, and ntfy. First run does a full
-image build. Open `http://localhost:7000` after the containers are healthy.
+To include optional extras in the image (PDF viewer, Office extraction; includes AGPL PyMuPDF), build with `docker compose build --build-arg INSTALL_OPTIONAL=true` before `up`.
 
-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:
+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.
+
+### Native Linux / macOS
 ```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:
-```bash
-git clone <your-odysseus-repo-url>
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
 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
-uvicorn app:app --host 0.0.0.0 --port 7000
+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. The app itself is lightweight; local model serving is the
+heavy part and depends on the model, runtime, GPU, and VRAM, so small hosts can
+connect to API or remote model servers instead. 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)
+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
+```
+
+The script also reads `.env` at startup, so `APP_BIND=0.0.0.0` and `APP_PORT`
+set there are picked up automatically without a command-line override each run.
+
+Keep `AUTH_ENABLED=true` (the default) before binding outside loopback. 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
+```
+
+**Docker GPU overlays.** CPU-only users can skip this section. Cookbook can
+only detect GPUs that Docker exposes to the container — if the host runtime or
+device passthrough is not configured, Cookbook sees the iGPU, another card, or
+CPU instead of your intended GPU.
+
+For NVIDIA, `scripts/check-docker-gpu.sh` diagnoses GPU passthrough and can
+optionally install the host runtime or update `.env`.
+
+```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 setup is read-only diagnostic plus manual `.env` edit. Run:
+
+```bash
+scripts/check-docker-amd-gpu.sh
+```
+
+Then add the reported values to `.env`, replacing `RENDER_GID` with your host's
+numeric render group id:
+
+```bash
+COMPOSE_FILE=docker-compose.yml:docker/gpu.amd.yml
+RENDER_GID=989
+```
+
+For NVIDIA/AMD GPU support, also read the comments in the selected overlay file: docker/gpu.nvidia.yml or docker/gpu.amd.yml.
+
+**Stack-management UIs (Portainer, Coolify, Dockhand, etc.).** These tools
+often accept only a single Compose file and do not reliably honor `COMPOSE_FILE`
+or multiple `-f` overlays. CLI users should keep using the `COMPOSE_FILE`
+overlay workflow above. For stack UIs, point the stack at one of the standalone
+files instead, which bundle the base stack plus the GPU settings:
+
+- `docker-compose.gpu-nvidia.yml` — still requires the NVIDIA Container Toolkit
+  on the host.
+- `docker-compose.gpu-amd.yml` — still requires host ROCm/kfd/DRI setup, the
+  `video`/`render` group membership, and `RENDER_GID` when needed.
+
+The base `docker-compose.yml` plus the `docker/gpu.*.yml` overlays remain the
+source of truth; the standalone files mirror them for single-file deployments.
+
+Verify after enabling either overlay:
+
+```bash
+docker compose exec odysseus nvidia-smi -L   # NVIDIA
+docker compose exec odysseus sh -lc 'test -e /dev/kfd && test -d /dev/dri && ls -l /dev/kfd /dev/dri/renderD*'  # 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.
+>
+> The same split applies to AMD/ROCm: seeing `/dev/kfd` and `/dev/dri` inside
+> the container confirms device passthrough, not ROCm userspace or a
+> ROCm-enabled vLLM/llama.cpp build. `rocm-smi` and `rocminfo` are not expected
+> inside the slim Odysseus image.
+
+**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
+```
+
+This connects Odysseus in Docker to an Ollama server that is already running on
+your host machine; it does not start Ollama inside the container.
+`host.docker.internal` is Docker's hostname for the host machine from inside the
+container. Cookbook **Serve** is a separate workflow for serving downloaded
+models through Odysseus/llama.cpp, so Windows users with an existing Ollama
+install usually only need to add the endpoint in Settings.
+
+**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
-git clone <your-odysseus-repo-url>
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
 cd odysseus
-python -m venv venv
+powershell -ExecutionPolicy Bypass -File .\launch-windows.ps1
+```
+
+Or do it by hand:
+
+```powershell
+git clone https://github.com/pewdiepie-archdaemon/odysseus.git
+cd odysseus
+py -3.11 -m venv venv
 venv\Scripts\Activate.ps1
 pip install -r requirements.txt
 python setup.py
-uvicorn app:app --host 0.0.0.0 --port 7000
+python -m uvicorn app:app --host 127.0.0.1 --port 7000
 ```
 
+If `python` points at an older interpreter, use `py -3.12` (or another installed
+3.11+ version) for the venv step.
+
+**Requirements:** Python 3.11+. The core app (chat, agent, memory, documents,
+email, calendar, deep research) runs fully native. For full **Cookbook** background
+model downloads and the agent shell tool, also install
+[Git for Windows](https://git-scm.com/download/win) (provides `bash.exe`).
+Local GPU *serving* of vLLM/SGLang needs Linux/WSL2; for a local model on Windows,
+[Ollama](https://ollama.com/download) is the easiest path — point Odysseus at
+`http://localhost:11434/v1` in Settings.
+
 Open `http://localhost:7000`, log in with the generated admin password,
 and configure everything else inside **Settings**.
 
+## Troubleshooting & Advanced Setup
+
+### `chromadb-client` conflicts with embedded ChromaDB
+If `chromadb-client` (the lightweight HTTP-only package) is installed alongside the full `chromadb` package, Odysseus starts but ChromaDB silently falls back to HTTP-only mode and fails.
+
+**Fix:** uninstall `chromadb-client` and force-reinstall the full package:
+```bash
+./venv/bin/pip uninstall chromadb-client -y
+./venv/bin/pip install --force-reinstall chromadb
+```
+
+### HTTPS + LAN/Tailscale exposure
+To expose Odysseus on a local network or Tailscale with HTTPS:
+1. Change the bind address to `0.0.0.0` in `.env` (`APP_BIND=0.0.0.0` or `ODYSSEUS_HOST=0.0.0.0`).
+2. Generate a locally-trusted cert for your LAN/Tailscale IPs using [mkcert](https://github.com/FiloSottile/mkcert):
+   ```bash
+   mkcert -install
+   mkcert -cert-file cert.pem -key-file key.pem 192.168.1.100 tailscale-ip
+   ```
+3. Run `uvicorn` with the generated certs:
+   ```bash
+   python -m uvicorn app:app --host 0.0.0.0 --port 7000 --ssl-certfile=cert.pem --ssl-keyfile=key.pem
+   ```
+4. Install the `mkcert` CA on any other device you want to access Odysseus from (e.g., for iOS, email the `rootCA.pem` to yourself, install the profile, and trust it in Certificate Trust Settings).
+
+### Optional Dependencies
+`requirements-optional.txt` contains packages that unlock extra features. It is not installed by default.
+
+| Package | Feature unlocked |
+|---------|-----------------|
+| `faster-whisper` | Local speech-to-text (microphone -> text) via the "local" STT provider. |
+| `duckduckgo-search` | DuckDuckGo as a search provider option. |
+| `PyMuPDF` | PDF page rendering in the side viewer panel and form-filling. (Note: AGPL-3.0) |
+| `markitdown` | Office/EPUB document text extraction (converts .docx/.xlsx/.pptx/.xls/.epub to Markdown). |
+
 ## Security Notes
 Odysseus is a self-hosted workspace with powerful local tools: shell access, file uploads, model downloads, web research, email/calendar integrations, and API tokens. Treat it like an admin console.
 
 - Keep `AUTH_ENABLED=true` for any network-accessible deployment.
-- Do not expose it directly to the public internet without HTTPS and a trusted reverse proxy.
-- Keep `data/`, `.env`, logs, databases, and uploaded/generated media out of Git. They are ignored by default.
+- Keep `LOCALHOST_BYPASS=false` outside local development.
+- Use `SECURE_COOKIES=true` when Odysseus is served through HTTPS by a trusted reverse proxy or private access gateway.
+- 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.
+Common internal-only ports from the default docs/compose setup:
+
+| Port | Service |
+|---|---|
+| `7000` | Odysseus raw app port |
+| `8080` | SearXNG |
+| `8091` | ntfy |
+| `8100` | ChromaDB host port for manual/compose access |
+| `11434` | Ollama |
+| `8000-8020` | Common local model/provider APIs |

-### Bundled services
-Docker Compose includes these 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 `localhost:8100`.
-  - **SearXNG** → meta search for web search. In Docker, Odysseus connects to `searxng:8080`; from the host it is exposed only on `127.0.0.1:8080`.
-  - **ntfy** → local notification service, exposed as `localhost: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.
 
-### Optional external services
-  - **Ollama** → local LLM server -- [ollama.ai](https://ollama.ai)
+To enable the browser MCP (page navigation, screenshots, vision), run once:
+
+```bash
+npx -y @playwright/mcp@latest --version
+```
+
+That installs `@playwright/mcp` plus Playwright (~300MB total). Restart Odysseus and the server will register at startup.

+  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.
+- Email performance audit. Fetching, searching, opening, deleting, and sending
+  email can feel slow, especially over IMAP/SMTP providers with high latency.
+  Need someone who knows mail performance to profile the current flow, identify
+  whether the bottleneck is IMAP folder select/fetch, cache invalidation,
+  attachment/body loading, SMTP handshakes, or frontend refresh behavior, then
+  propose safer caching/prefetch/batching without breaking multi-account state.
 - 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.

+- 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`.

+# Threat Model
+
+Odysseus is a **self-hosted AI workspace with privileged local access**. This document states the trust boundary so contributors can reason about security decisions without reading through the full auth and middleware stack.
+
+## Trust Boundary
+
+Odysseus is designed for **trusted users on a private network**, not public exposure. The README describes it as "treat it like an admin console" — that framing is accurate. A logged-in admin can execute shell commands, read and write files, send email, and control model serving. This is intentional. The threat model does not try to prevent admins from doing these things. It does try to prevent:
+
+- Unauthenticated access
+- Non-admins reaching admin-only capabilities
+- The AI agent acting on instructions injected through untrusted content (web results, emails, fetched pages, memories)
+- Internal services (ChromaDB, Ollama, SearXNG, etc.) being reachable from outside the host
+
+## Roles and Capabilities
+
+| Capability | Admin | Non-admin (default) |
+|---|---|---|
+| Chat with agent | ✓ | ✓ |
+| Browser tool | ✓ | ✓ |
+| Documents | ✓ | ✓ |
+| Research mode | ✓ | ✓ |
+| Image generation | ✓ | ✓ |
+| Memory management | ✓ | ✓ |
+| Shell / Python execution | ✓ | ✗ |
+| File read / write | ✓ | ✗ |
+| Email send / read | ✓ | ✗ |
+| MCP tools | ✓ | ✗ |
+| Calendar management | ✓ | ✗ |
+| Token / webhook management | ✓ | ✗ |
+| Model serving | ✓ | ✗ |
+| Vault | ✓ | ✗ |
+| Settings | ✓ | ✗ |
+
+Non-admin defaults are in `core/auth.py:DEFAULT_PRIVILEGES`. Tool enforcement is in `src/tool_security.py:NON_ADMIN_BLOCKED_TOOLS`. Any tool whose name starts with `mcp__` is also blocked for non-admins. Admins always get full access regardless of stored privilege values.
+
+## Authentication
+
+- **Sessions:** bcrypt passwords, 7-day session tokens stored atomically in `data/sessions.json` via `core/atomic_io.py`.
+- **2FA:** TOTP with 8 single-use backup codes. Verified after password check, before session issuance.
+- **Reserved usernames:** `internal-tool`, `api`, `demo`, `system` cannot be registered or renamed into. Defined in `core/auth.py:RESERVED_USERNAMES`.
+  - `internal-tool` is security-critical: `core/middleware.py:require_admin` treats any request where `request.state.current_user == "internal-tool"` as the in-process tool loopback and grants admin unconditionally. A real account with that name would silently pass every `require_admin` check.
+- **Orphan sessions:** `validate_token` re-checks that the user record still exists on every call. A deleted user's cookie is dropped on next request rather than continuing to authenticate.
+
+## Internal Tool Loopback
+
+Agent tool calls reach admin-gated HTTP routes over an in-process HTTP loopback. The mechanism:
+
+1. At app startup, `core/middleware.py` generates a random `INTERNAL_TOOL_TOKEN` via `secrets.token_hex(32)`. It is never persisted and never sent to clients.
+2. Loopback requests carry `X-Odysseus-Internal-Token: <token>` or have `request.state.current_user` already set to `"internal-tool"` by the auth middleware.
+3. `require_admin` recognises either signal and grants access without checking the session user.
+
+The agent may be running in a non-admin user's session, but tool dispatch first calls `src/tool_security.py:owner_is_admin_or_single_user` to verify the session owner is an admin before issuing any loopback call. Non-admin users cannot invoke admin tools even via the agent.
+
+## Prompt-Injection Hardening
+
+External content that reaches the LLM is treated as untrusted via `src/prompt_security.py`:
+
+- `untrusted_context_message(label, content)` wraps the content in a `user`-role message with a header block instructing the model not to follow instructions inside it. Content goes in as data, not as a system instruction.
+- `UNTRUSTED_CONTEXT_POLICY` is a system-prompt preamble that states the same policy at the top of every session where untrusted data may appear.
+
+**Untrusted surfaces that must go through this wrapper:** web search results, fetched URLs, emails (read), saved memories, skill text, notes, and any tool output sourced from outside the server. Injecting untrusted content directly into the system role is a security bug.
+
+## Security Headers
+
+`core/middleware.py:SecurityHeadersMiddleware` sets headers on every response:
+
+- `X-Frame-Options: DENY` + `frame-ancestors 'none'` on all routes except tool-render iframes (which are sandboxed at the HTML level).
+- `X-Content-Type-Options: nosniff` and `Referrer-Policy: no-referrer` everywhere.
+- **CSP:** nonce-based `script-src 'self' 'nonce-{nonce}' https://cdn.jsdelivr.net`. `style-src 'unsafe-inline'` is intentionally kept — `static/index.html` ships inline `<style>` blocks and JS modules set `style=""` attributes at runtime. Inline styles do not execute script so the risk is visual-only. Removing this requires templating the HTML files and auditing all JS-set style attributes.
+
+## Known Gaps
+
+These are open, acknowledged, and contributor help is welcome:
+
+1. **No shell/filesystem sandbox.** The agent `bash` and `read_file`/`write_file` tools run as the app process user with no network egress filtering or filesystem confinement. A successful prompt-injection reaching a shell-enabled admin session can make outbound requests to internal services. See #1058 for the sandbox proposal.
+
+2. **SSRF via `/api/v1/chat` `base_url` parameter.** A chat-scoped API token can supply an arbitrary `base_url`; the server forwards the LLM request to that host without validating the scheme or address. PR #1039 fixes this.
+
+3. **`src/search/` partial consolidation.** `src.search.core` and `src.search.providers` correctly alias `services.search` via `sys.modules` replacement. `analytics`, `cache`, `content`, `query`, and `ranking` are still independent copies that can drift. The SSRF regression tests in `tests/test_webhook_ssrf_resilience.py` test `src.webhook_manager` directly (separate from search), so the safety net there is intact. See #1058.
+
+4. **Token scopes are coarse.** There is no way to grant a session a subset of the owning user's privileges. Companion/mobile tokens carry either `chat` or `admin` scope with no per-capability granularity.

+# 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`.

+"""Companion bridge — /api/companion/*.
+
+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
+/pair only renders a form.

+# PR Blocker Audit
+
+`scripts/pr_blocker_audit.py` is a small, read-only triage helper for maintainers who need to inspect open pull request overlap before reviewing or starting related work.
+
+It is a triage helper, not a replacement for maintainer judgment.
+
+## What it does
+
+- Reads open PR metadata from a local JSON file or from `gh`.
+- Reports files touched by more than one open PR.
+- Groups active work into broad code areas.
+- Ranks PRs with a deterministic heuristic score.
+- Flags possible duplicate candidates based on title keyword overlap and changed-file similarity.
+- Suggests quieter areas for conservative new work.
+- Prints Markdown by default, compact terminal output when requested, or machine-readable JSON.
+
+## What it does not do
+
+- It does not post comments.
+- It does not review, approve, label, close, merge, or otherwise mutate PRs.
+- It does not add or run GitHub Actions.
+- It does not import the Odysseus application package.
+- It does not claim that a PR is definitely blocked or duplicated.
+
+## Read-only safety guarantee
+
+Offline mode only reads a local JSON file. Live mode runs read-only GitHub CLI commands:
+
+```bash
+gh pr list --repo OWNER/REPO --state open --limit 1000 --json number,title,author,files,mergeStateStatus,reviewDecision,updatedAt,url
+```
+
+If a PR from that list has missing or empty changed-file metadata, live mode fills it with read-only per-PR REST calls:
+
+```bash
+gh api --paginate "repos/OWNER/REPO/pulls/NUMBER/files?per_page=100"
+```
+
+If that GraphQL-backed command fails, it falls back to:
+
+```bash
+gh api --paginate "repos/OWNER/REPO/pulls?state=open&per_page=100"
+```
+
+Per-PR file fetching makes live overlap results useful, but it can be slower on repositories with hundreds of open PRs.
+
+## Generate input JSON
+
+For repeatable offline audits, capture PR metadata first:
+
+```bash
+gh pr list --repo OWNER/REPO --state open --limit 1000 --json number,title,author,files,mergeStateStatus,reviewDecision,updatedAt,url > open-prs.json
+```
+
+## Run offline mode
+
+```bash
+python3 scripts/pr_blocker_audit.py --input open-prs.json
+```
+
+## Run live mode
+
+```bash
+python3 scripts/pr_blocker_audit.py --repo OWNER/REPO
+```
+
+Live mode fetches up to 1000 open PRs by default. Use `--limit` to cap how many open PRs are fetched and analyzed, and `--top` to cap how many rows are displayed in ranked sections:
+
+```bash
+python3 scripts/pr_blocker_audit.py --repo OWNER/REPO --limit 50 --top 10
+```
+
+Live mode may take time on large PR queues because it fetches changed-file metadata for each PR that did not include it in the initial list response. Progress is shown on `stderr` by default only when `stderr` is a TTY:
+
+```bash
+python3 scripts/pr_blocker_audit.py --repo OWNER/REPO --progress auto
+python3 scripts/pr_blocker_audit.py --repo OWNER/REPO --progress always
+python3 scripts/pr_blocker_audit.py --repo OWNER/REPO --progress never
+```
+
+Use `--quiet` to suppress progress and non-fatal warning output. Progress and warnings never go to `stdout`, so redirected reports and `--output` files remain clean.
+
+For a faster metadata-only scan, skip changed-file metadata entirely:
+
+```bash
+python3 scripts/pr_blocker_audit.py --repo OWNER/REPO --no-fetch-files
+```
+
+## JSON output
+
+Use `--format json` for machine-readable output suitable for scripting or downstream tooling:
+
+```bash
+python3 scripts/pr_blocker_audit.py --input open-prs.json --format json
+python3 scripts/pr_blocker_audit.py --input open-prs.json --format json --output report.json
+```
+
+JSON output is stable and deterministic for the same input. It uses `sort_keys=True` so field order does not vary between runs. It never includes ANSI escape codes, even with `--color always`. Progress text is always `stderr`-only and never appears in JSON output.
+
+The top-level object contains these keys:
+
+- `summary` — scalar overview: `total_prs_analyzed`, `unique_files_touched`, `prs_missing_changed_file_metadata`, `main_overlap_drivers`, `highest_risk_areas`, `recommended_first_review_target`
+- `locked_areas` — list of objects with `area`, `files` (top paths as a string), `prs` (list of PR numbers), `why`, `priority`
+- `hot_files` — list of objects with `file`, `pr_count`, `pr_numbers` (list of PR numbers); capped at `--top`
+- `review_priorities` — ranked list with `rank`, `number`, `score`, `title`, `url`, `merge_state`, `review_decision`, `reasons` (list); capped at `--top`
+- `duplicate_candidates` — list of objects with `pr_numbers` (list) and `titles` (list, one entry per PR in the group)
+- `safer_areas` — list of strings
+
+## Write output to a file
+
+```bash
+python3 scripts/pr_blocker_audit.py --input open-prs.json --output pr-blocker-report.md
+python3 scripts/pr_blocker_audit.py --input open-prs.json --format json --output report.json
+```
+
+Markdown and JSON output never include ANSI color codes. ANSI codes are stripped defensively when writing any output file.
+
+## Terminal output and color
+
+Use terminal output for quick interactive scans:
+
+```bash
+python3 scripts/pr_blocker_audit.py --input open-prs.json --format terminal
+```
+
+Terminal output includes locked areas, hot files, review / blocker priorities, possible duplicate candidates, and safer areas.
+
+Color is readability-only. It is never included in Markdown reports and is stripped defensively when writing output files. Color modes are:
+
+```bash
+python3 scripts/pr_blocker_audit.py --input open-prs.json --format terminal --color auto
+python3 scripts/pr_blocker_audit.py --input open-prs.json --format terminal --color always
+python3 scripts/pr_blocker_audit.py --input open-prs.json --format terminal --color never
+```
+
+`--no-color` is kept as an alias for `--color never`. With `--color auto`, color is used only for terminal output on a TTY when `NO_COLOR` is not set and output is not being written to a file.
+
+## Interpret locked areas
+
+Locked areas are broad categories with one or more open PRs. An area is higher priority when several PRs touch it, when PRs share files, or when the highest scoring PR in that area has risk signals. Treat this as a prompt to inspect the PRs together.
+
+`PRs missing changed-file metadata` counts PRs that still had no changed-file paths after live file fetching, or PRs from offline input that did not include files. Those PRs can still appear in area summaries from title matching, but file overlap analysis is weaker for them.
+
+`Docs / tooling / tests` is conservative: runtime PRs are not classified there just because they include tests or README changes. Docs-only, README-only, scripts-only, tests-only, or strongly titled docs/tooling/test work still maps there.
+
+`Other / unclassified` is kept visible for PRs that do not match the area rules. When most of it comes from missing file metadata, the report summarizes that instead of letting long PR lists dominate the locked-area section.
+
+## Interpret duplicate candidates
+
+Duplicate candidates are labeled as possible duplicate / needs human review. The script groups PRs only when their file sets are highly similar and their titles share meaningful keywords. Similar PRs can still be complementary.
+
+## Interpret heuristic scores
+
+The review priority score is deterministic for the same input. Recency is measured against the newest parseable PR update timestamp in the input, and the score uses simple weights for:
+
+- direct auth, bearer-token, API-token, privilege, or permission lifecycle signals
+- security, secret, or data exposure keywords
+- persistence, migration, database, SQLite, or Postgres keywords
+- memory, vector, RAG, embedding, or retrieval keywords
+- overlapping changed files
+- clean merge state as a small actionability signal
+- review state
+- recently updated PRs when timestamp data exists
+
+Higher scores mean "inspect earlier", not "correct" or "merge-ready". Broad PRs can score high because they overlap many files and may block other work, but they still need normal review and validation.
+
+Dirty, blocked, conflicting, and unknown merge states are shown as risk/caution reasons. They do not add importance points by themselves.
+
+## Design note: intentional single-script layout
+
+`pr_blocker_audit.py` is intentionally kept as one standalone script. The goal is to keep this maintainer/contributor workflow helper low-friction while broader repo tooling and test-suite conventions are still evolving. Splitting it into packages or modules is not ruled out, but is deferred until there is a clearer settled pattern to follow.
+
+## Limitations
+
+- Some PRs may still lack changed files if GitHub file metadata calls fail or metadata-only mode is used.
+- Area classification is intentionally small and editable.
+- Title keyword matching misses semantic duplicates.
+- Heuristic scoring cannot know project strategy, reviewer availability, or hidden dependency chains.
+- Empty or missing file metadata produces a valid report but weak overlap analysis.
+
+## Validation
+
+```bash
+python3 -m py_compile scripts/pr_blocker_audit.py tests/test_pr_blocker_audit.py
+python3 -m pytest tests/test_pr_blocker_audit.py -q

+# Odysseus Claude Code Integration
+
+This directory contains the Claude Code skill bundle for Odysseus.
+
+## User Flow
+
+1. Open Odysseus Settings > Integrations.
+2. Add a Claude Agent.
+3. Copy the full setup commands shown after the generated token.
+4. Toggle the tools Claude is allowed to use.
+5. Configure the terminal Claude Code session:
+
+```bash
+export ODYSSEUS_URL=http://your-odysseus-host:7000
+export ODYSSEUS_API_TOKEN=ody_generated_token
+mkdir -p ~/.claude
+curl -fsSL -H "Authorization: Bearer $ODYSSEUS_API_TOKEN" "$ODYSSEUS_URL/api/claude/plugin.zip" -o /tmp/odysseus-claude-skill.zip
+python3 -m zipfile -e /tmp/odysseus-claude-skill.zip ~/.claude/
+```
+
+Claude Code auto-loads anything under `~/.claude/skills/`, so the `odysseus` skill is
+available in any session that has `ODYSSEUS_URL` and `ODYSSEUS_API_TOKEN` in its
+environment.
+
+## What's in the bundle
+
+- `skills/odysseus/SKILL.md` — the skill definition Claude Code reads.
+- `skills/odysseus/scripts/odysseus_api.py` — small helper that calls the scoped
+  `/api/codex/*` endpoints (these are the canonical scope-gated agent API; the
+  `codex` path is historic and shared by all agent integrations).
+
+## Scope enforcement
+
+The token is scope-gated. Every tool surface is checked server-side in Odysseus,
+so even if Claude tries to call a forbidden endpoint, it gets `403` until the
+user enables the matching toggle in Settings > Integrations > Claude Agent.

+name: odysseus
+description: Use when the user asks Claude Code to read or write Odysseus data (todos, email, calendar, memory, documents) or to launch/monitor/stop a Cookbook model-serve task through the scoped Claude Agent API. Requires ODYSSEUS_URL and ODYSSEUS_API_TOKEN.
+---
+
+# Odysseus
+
+Use this skill when a user asks to interact with Odysseus from Claude Code.
+
+## Configuration
+
+Expect these environment variables:
+
+- `ODYSSEUS_URL`: Base URL for the user's Odysseus instance, for example `http://127.0.0.1:7000`.
+- `ODYSSEUS_API_TOKEN`: Scoped API token created in Odysseus Settings > Integrations > Add Integration > Claude Agent.
+
+If either value is missing, do not guess credentials. Tell the user to create a Claude Agent token in Odysseus Settings and expose both values to the terminal session.
+
+## When to use what
+
+- **Reminder ("remind me at 5pm to do X")** → TODO with `due_date`. The due_date IS the reminder — it fires a notification automatically via the user's configured channel (browser/email/ntfy). **Do NOT create a calendar event for a reminder.** Creating a calendar event named "Reminder" does NOT trigger a notification — it's just a time block on the calendar.
+- **Calendar event ("meeting at 3pm", "dentist Tuesday 10am")** → calendar event. Use for scheduled time blocks, meetings, appointments, recurring schedules. These show up on the calendar grid; reminders for them are configured separately in Odysseus settings.
+- **Note / freeform info ("note that the wifi password is ...")** → memory or todo without a due_date (depending on whether it's a fact about the user or an action item).
+- **Persistent fact / preference about the user** → memory.
+
+If the user says "reminder" + a time, default to TODO with due_date. Only switch to calendar if the user explicitly says "calendar", "event", "meeting", "appointment", or describes a time *range*.
+
+## Safety
+
+- All Odysseus data access MUST go through the scoped HTTP API under `/api/codex/*` (the canonical scope-gated agent API, shared by all agent integrations).
+- Check `/api/codex/capabilities` before using a tool surface.
+- Treat `403` as an intentional Settings restriction. Do not work around it.
+- Do not use SSH, Docker, direct Python imports, SQLite queries, MCP internals, browser cookies, or local files to read/write Odysseus user data.
+- Do not call helpers like `do_manage_notes`, email MCP internals, or database sessions directly for user data, even if shell access exists.
+- Never send email directly unless the user explicitly asks to send and the token has a send-capable scope.
+- Keep actions scoped to the token owner.
+
+## Todos
+
+The scoped agent API supports todos/checklists:
+
+- `GET /api/codex/todos`
+- `POST /api/codex/todos`
+
+Use the bundled helper script when available:
+
+```bash
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py capabilities
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py todos list
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py todos add "Follow up"
+```
+
+Supported todo actions are `list`, `add`, `update`, `delete`, and `toggle_item`.
+
+**Reminders (todos with a due date)** — the backend parses natural language. Send `due_date` in the body via the generic POST so the time becomes a structured reminder, NOT a literal substring inside the title. The `todos add TITLE` shortcut only sets the title, so use the POST form for anything with a time:
+
+```bash
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py POST /api/codex/todos '{"action":"add","title":"Call dentist","due_date":"tomorrow at 5pm"}'
+```
+
+The backend accepts both ISO timestamps and natural language like `"tomorrow 5pm"`, `"next Monday 9am"`, `"in 2 hours"`. It anchors to the user's timezone.
+
+## Email
+
+The scoped agent API supports email reads:
+
+- `GET /api/codex/emails?folder=INBOX&limit=10&offset=0&filter=all`
+- `GET /api/codex/emails/{uid}?folder=INBOX`
+
+Use the bundled helper script when available:
+
+```bash
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py emails list 5
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py emails read UID
+```
+
+If `/api/codex/capabilities` does not show `email.read: true`, do not inspect email. Ask the user to enable Email read in the Claude Agent settings.
+
+## Memory
+
+- `GET /api/codex/memory` — list memories for the token owner.
+- `POST /api/codex/memory` — body `{"text": "...", "category": "fact", "source": "user", "session_id": null}`. Requires `memory:write`.
+- `DELETE /api/codex/memory/{memory_id}` — remove a memory entry. Requires `memory:write`.
+
+```bash
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py GET /api/codex/memory
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py POST /api/codex/memory '{"text":"User prefers SI units","category":"preference"}'
+```
+
+## Calendar
+
+- `GET /api/codex/calendar/events?start=ISO&end=ISO` — list events in window.
+- `POST /api/codex/calendar/events` — body matches `EventCreate` (`summary`, `dtstart`, `dtend`, `all_day`, `description`, `location`, `calendar_href`, `rrule`, `color`). Requires `calendar:write`.
+- `DELETE /api/codex/calendar/events/{uid}` — delete event by uid (the value returned in the POST response). Requires `calendar:write`.
+
+## Documents
+
+- `GET /api/codex/documents?search=...&limit=50` — paginated library.
+- `GET /api/codex/documents/{doc_id}` — fetch one document.
+- `POST /api/codex/documents` — body `{"session_id": "...", "title": "...", "content": "...", "language": "markdown"}`. Requires `documents:write`.
+- `DELETE /api/codex/documents/{doc_id}` — delete a document. Requires `documents:write`.
+
+## Email draft + send
+
+- `POST /api/codex/emails/draft` — body matches `SendEmailRequest` (`to`, `cc`, `bcc`, `subject`, `body`, `body_html`, `attachments`, `account_id`, `in_reply_to`, `references`). Requires `email:draft` (or `email:send`).
+- `POST /api/codex/emails/send` — same body. Requires `email:send`. Never send without explicit user instruction.
+
+## Cookbook serve (debug a failing model launch)
+
+The Cookbook surface lets you reproduce what a human would do in Odysseus → Cookbook: read which serves are running, tail their tmux output to see why they crashed, edit the launch command, relaunch, kill a stuck one. Use this when the user is debugging a model server that won't come up (compute-capability errors, OOM, missing kernels, wrong attention backend, etc.).

+- `GET /api/codex/cookbook/tasks` — list active serve/download/install tasks (sessionId, type, status, repo_id, remoteHost, payload._cmd). Requires `cookbook:read`.
+- `GET /api/codex/cookbook/servers` — list configured servers (name, host, port, env type + path, model dirs). Requires `cookbook:read`.
+- `GET /api/codex/cookbook/cached?host=<NAME>` — list models already cached on the named server (HF cache + Ollama + extra modelDirs). Call BEFORE `serve` to see what's already on disk. Requires `cookbook:read`.
+- `GET /api/codex/cookbook/presets` — list saved serve presets (model + host + port + cmd). The user's saved preset usually has a working cmd — try `preset NAME` before composing your own. Requires `cookbook:read`.
+- `GET /api/codex/cookbook/output/{session_id}?tail=400` — read the last N lines of the task's persistent log file (preferred) or tmux pane (fallback). The log file persists across vllm crashes, so this returns the actual Python traceback even after the bash prompt + neofetch banner overwrites the pane. Default tail=400. Requires `cookbook:read`.
+- `POST /api/codex/cookbook/serve` — launch a serve task. Body matches `ServeRequest`: `{ repo_id, cmd, remote_host?, ssh_port?, env_prefix?, gpus?, platform? }`. The `cmd` is validated: leading binary must be `vllm`/`python3`/`sglang`/`llama-server`/`ollama`/`node`/`npx`. NEVER prefix with `cd …`, `source …`, or chain with `&&`/`||`/`;`/`$(...)` — the validator rejects shell metacharacters. The venv activation (`env_prefix`) is added automatically from the host's saved settings, so pass the bare binary + args. Requires `cookbook:launch`.
+- `POST /api/codex/cookbook/preset/{name}` — launch a saved preset by name. Reuses the working cmd + host the user already saved. Requires `cookbook:launch`.
+- `POST /api/codex/cookbook/adopt` — register an externally-launched tmux session into cookbook tracking. Body: `{ tmux_session, model, host?, port? }`. Use this when serve_model rejected a cmd and you fell back to direct ssh+tmux — without adoption, the session is invisible to the UI. Requires `cookbook:launch`.
+- `POST /api/codex/cookbook/stop/{session_id}` — kill the tmux session for that task. Requires `cookbook:launch`.
+
+```bash
+# Survey what's running
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py cookbook tasks
+
+# Tail the failing one (sessionId from `cookbook tasks`)
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py cookbook output serve-abc12345 400
+
+# Stop the previous attempt before you try a new flag set
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py cookbook stop serve-abc12345
+
+# Relaunch with new flags. cmd MUST begin with one of the allowlisted binaries.
+python3 ~/.claude/skills/odysseus/scripts/odysseus_api.py cookbook serve \
+  /mnt/HADES/models/Qwen3.5-397B-A17B-AWQ \
+  "vllm serve /mnt/HADES/models/Qwen3.5-397B-A17B-AWQ --host 0.0.0.0 --port 8001 --tensor-parallel-size 8 --max-model-len 262144 --gpu-memory-utilization 0.90 --dtype auto --max-num-seqs 8 --trust-remote-code --enable-expert-parallel --enable-auto-tool-choice --tool-call-parser qwen3_coder --reasoning-parser qwen3" \
+  pewds@192.168.1.12
+```
+
+**Debug loop pattern:** when a serve is failing, the productive sequence is
+
+1. `cookbook tasks` → find the failing sessionId.
+2. `cookbook output SID 600` → read the last 600 lines, find the actual root-cause line (often above the visible tail because tmux scrollback rolled — request a larger `tail` if the error references "above").
+3. `cookbook stop SID` — kill the previous attempt before relaunching; two serves on the same `--port` collide.
+4. `cookbook serve repo "new cmd"` — try the next variation. Wait ~20s, then `cookbook output` on the new sessionId.
+
+**Hard limits this surface enforces:**
+- `cookbook serve` cmd allowlist + shell-metacharacter rejection — you cannot run arbitrary shell, only model-server binaries.
+- `cookbook stop` only targets task sessionIds matching `[a-zA-Z0-9_-]+`.
+- The agent CAN spawn GPU-pinning long-lived processes — always `cookbook stop` your previous attempt before relaunching, and check `cookbook tasks` for collisions on the same `--port` before launching.
+
+## Forbidden Bypass Pattern
+
+If you are about to reach the Odysseus host/container, import app internals, query the database, or call MCP helper modules directly, stop. Those paths bypass Odysseus Settings and token scopes. Ask the user to enable the relevant Claude Agent tool toggle instead.

+## User Flow
+
+1. Open Odysseus Settings > Integrations.
+2. Add a Codex Agent.
+3. Copy the full setup commands shown after the generated token.
+4. Toggle the tools Codex is allowed to use.
+5. Configure the terminal Codex session:
+
+```bash
+export ODYSSEUS_URL=http://your-odysseus-host:7000
+export ODYSSEUS_API_TOKEN=ody_generated_token
+mkdir -p ~/plugins
+curl -fsSL -H "Authorization: Bearer $ODYSSEUS_API_TOKEN" "$ODYSSEUS_URL/api/codex/plugin.zip" -o /tmp/odysseus-codex-plugin.zip

+PY
+codex plugin add odysseus@personal
+```
+
+6. Verify:
+
+```bash
+python3 ~/plugins/odysseus/scripts/odysseus_api.py capabilities
+```
+
+Codex must use `/api/codex/*` endpoints. SSH, Docker, direct Python imports, database queries, and MCP internals bypass Odysseus Settings and must not be used for user data access.

+name: odysseus
+description: Use when the user asks Codex to read or write Odysseus data (todos, email, calendar, memory, documents) or to launch/monitor/stop a Cookbook model-serve task through the scoped Codex Agent API. Requires ODYSSEUS_URL and ODYSSEUS_API_TOKEN.
+---
+
+# Odysseus
+
+Use this skill when a user asks to interact with Odysseus from Codex.
+
+## Configuration
+
+Expect these environment variables:
+
+- `ODYSSEUS_URL`: Base URL for the user's Odysseus instance, for example `http://127.0.0.1:7000`.
+- `ODYSSEUS_API_TOKEN`: Scoped API token created in Odysseus Settings > Integrations > Add Integration > Codex Agent.
+
+If either value is missing, do not guess credentials. Tell the user to create a Codex Agent token in Odysseus Settings and expose both values to the terminal session.
+
+## When to use what
+
+- **Reminder ("remind me at 5pm to do X")** → TODO with `due_date`. The due_date IS the reminder — it fires a notification automatically via the user's configured channel (browser/email/ntfy). **Do NOT create a calendar event for a reminder.** Creating a calendar event named "Reminder" does NOT trigger a notification — it's just a time block on the calendar.
+- **Calendar event ("meeting at 3pm", "dentist Tuesday 10am")** → calendar event. Use for scheduled time blocks, meetings, appointments, recurring schedules. These show up on the calendar grid; reminders for them are configured separately in Odysseus settings.
+- **Note / freeform info ("note that the wifi password is ...")** → memory or todo without a due_date (depending on whether it's a fact about the user or an action item).
+- **Persistent fact / preference about the user** → memory.
+
+If the user says "reminder" + a time, default to TODO with due_date. Only switch to calendar if the user explicitly says "calendar", "event", "meeting", "appointment", or describes a time *range*.
+
+## Safety
+
+- All Odysseus data access MUST go through the scoped HTTP API under `/api/codex/*`.
+- Check `/api/codex/capabilities` before using a tool surface.
+- Treat `403` as an intentional Settings restriction. Do not work around it.
+- Do not use SSH, Docker, direct Python imports, SQLite queries, MCP internals, browser cookies, or local files to read/write Odysseus user data.
+- Do not call helpers like `do_manage_notes`, email MCP internals, or database sessions directly for user data, even if shell access exists.
+- Never send email directly unless the user explicitly asks to send and the token has a send-capable scope.
+- Keep actions scoped to the token owner.
+
+## Todos
+
+The Codex API supports todos/checklists:
+
+- `GET /api/codex/todos`
+- `POST /api/codex/todos`
+
+Use the bundled helper script when available:
+
+```bash
+python3 integrations/codex/scripts/odysseus_api.py capabilities
+python3 integrations/codex/scripts/odysseus_api.py todos list
+python3 integrations/codex/scripts/odysseus_api.py todos add "Follow up"
+```
+
+Supported todo actions are `list`, `add`, `update`, `delete`, and `toggle_item`.
+
+**Reminders (todos with a due date)** — the backend parses natural language. Send `due_date` in the body via the generic POST so the time becomes a structured reminder, NOT a literal substring inside the title. The `todos add TITLE` shortcut only sets the title, so use the POST form for anything with a time:
+
+```bash
+python3 integrations/codex/scripts/odysseus_api.py POST /api/codex/todos '{"action":"add","title":"Call dentist","due_date":"tomorrow at 5pm"}'
+```
+
+The backend accepts both ISO timestamps and natural language like `"tomorrow 5pm"`, `"next Monday 9am"`, `"in 2 hours"`. It anchors to the user's timezone.
+
+## Email
+
+The Codex API supports scoped email reads:
+
+- `GET /api/codex/emails?folder=INBOX&limit=10&offset=0&filter=all`
+- `GET /api/codex/emails/{uid}?folder=INBOX`
+
+Use the bundled helper script when available:
+
+```bash
+python3 integrations/codex/scripts/odysseus_api.py emails list 5
+python3 integrations/codex/scripts/odysseus_api.py emails read UID
+```
+
+If `/api/codex/capabilities` does not show `email.read: true`, do not inspect email. Ask the user to enable Email read in the Codex Agent settings.
+
+## Memory
+
+- `GET /api/codex/memory` — list memories for the token owner.
+- `POST /api/codex/memory` — body `{"text": "...", "category": "fact", "source": "user", "session_id": null}`. Requires `memory:write`.
+- `DELETE /api/codex/memory/{memory_id}` — remove a memory entry. Requires `memory:write`.
+
+```bash
+python3 integrations/codex/scripts/odysseus_api.py GET /api/codex/memory
+python3 integrations/codex/scripts/odysseus_api.py POST /api/codex/memory '{"text":"User prefers SI units","category":"preference"}'
+```
+
+## Calendar
+
+- `GET /api/codex/calendar/events?start=ISO&end=ISO` — list events in window.
+- `POST /api/codex/calendar/events` — body matches `EventCreate` (`summary`, `dtstart`, `dtend`, `all_day`, `description`, `location`, `calendar_href`, `rrule`, `color`). Requires `calendar:write`.
+- `DELETE /api/codex/calendar/events/{uid}` — delete event by uid (the value returned in the POST response). Requires `calendar:write`.
+
+## Documents
+
+- `GET /api/codex/documents?search=...&limit=50` — paginated library.
+- `GET /api/codex/documents/{doc_id}` — fetch one document.
+- `POST /api/codex/documents` — body `{"session_id": "...", "title": "...", "content": "...", "language": "markdown"}`. Requires `documents:write`.
+- `DELETE /api/codex/documents/{doc_id}` — delete a document. Requires `documents:write`.
+
+## Email draft + send
+
+- `POST /api/codex/emails/draft` — body matches `SendEmailRequest` (`to`, `cc`, `bcc`, `subject`, `body`, `body_html`, `attachments`, `account_id`, `in_reply_to`, `references`). Requires `email:draft` (or `email:send`).
+- `POST /api/codex/emails/send` — same body. Requires `email:send`. Never send without explicit user instruction.
+
+## Cookbook serve (debug a failing model launch)
+
+The Cookbook surface lets you reproduce what a human would do in Odysseus → Cookbook: read which serves are running, tail their tmux output to see why they crashed, edit the launch command, relaunch, kill a stuck one. Use this when the user is debugging a model server that won't come up (compute-capability errors, OOM, missing kernels, wrong attention backend, etc.).
+
+- `GET /api/codex/cookbook/tasks` — list active serve/download/install tasks (sessionId, type, status, repo_id, remoteHost, payload._cmd). Requires `cookbook:read`.
+- `GET /api/codex/cookbook/servers` — list configured servers (name, host, port, env type + path, model dirs). Requires `cookbook:read`.
+- `GET /api/codex/cookbook/cached?host=<NAME>` — list models already cached on the named server (HF cache + Ollama + extra modelDirs). Call BEFORE `serve` to see what's already on disk. Requires `cookbook:read`.
+- `GET /api/codex/cookbook/presets` — list saved serve presets (model + host + port + cmd). The user's saved preset usually has a working cmd — try `preset NAME` before composing your own. Requires `cookbook:read`.
+- `GET /api/codex/cookbook/output/{session_id}?tail=400` — read the last N lines of the task's persistent log file (preferred) or tmux pane (fallback). The log file persists across vllm crashes, so this returns the actual Python traceback even after the bash prompt + neofetch banner overwrites the pane. Default tail=400. Requires `cookbook:read`.
+- `POST /api/codex/cookbook/serve` — launch a serve task. Body matches `ServeRequest`: `{ repo_id, cmd, remote_host?, ssh_port?, env_prefix?, gpus?, platform? }`. The `cmd` is validated: leading binary must be `vllm`/`python3`/`sglang`/`llama-server`/`ollama`/`node`/`npx`. NEVER prefix with `cd …`, `source …`, or chain with `&&`/`||`/`;`/`$(...)` — the validator rejects shell metacharacters. The venv activation (`env_prefix`) is added automatically from the host's saved settings, so pass the bare binary + args. Requires `cookbook:launch`.
+- `POST /api/codex/cookbook/preset/{name}` — launch a saved preset by name. Reuses the working cmd + host the user already saved. Requires `cookbook:launch`.
+- `POST /api/codex/cookbook/adopt` — register an externally-launched tmux session into cookbook tracking. Body: `{ tmux_session, model, host?, port? }`. Use this when serve_model rejected a cmd and you fell back to direct ssh+tmux — without adoption, the session is invisible to the UI. Requires `cookbook:launch`.
+- `POST /api/codex/cookbook/stop/{session_id}` — kill the tmux session. Requires `cookbook:launch`.
+
+```bash
+python3 ~/plugins/odysseus/scripts/odysseus_api.py cookbook tasks
+python3 ~/plugins/odysseus/scripts/odysseus_api.py cookbook output serve-abc12345 400
+python3 ~/plugins/odysseus/scripts/odysseus_api.py cookbook stop serve-abc12345
+python3 ~/plugins/odysseus/scripts/odysseus_api.py cookbook serve \
+  /mnt/HADES/models/Qwen3.5-397B-A17B-AWQ \
+  "vllm serve /mnt/HADES/models/Qwen3.5-397B-A17B-AWQ --host 0.0.0.0 --port 8001 --tensor-parallel-size 8 --max-model-len 262144 --gpu-memory-utilization 0.90 --dtype auto --max-num-seqs 8 --trust-remote-code --enable-expert-parallel --enable-auto-tool-choice --tool-call-parser qwen3_coder --reasoning-parser qwen3" \
+  pewds@192.168.1.12
+```
+
+**Debug loop pattern:** `tasks` → `output SID 600` (find root cause; request larger `tail` if it references "above") → `stop SID` → `serve repo "new cmd"` → wait ~20s → `output` on the new sessionId.
+
+**Hard limits this surface enforces:**
+- `cookbook serve` cmd allowlist + shell-metacharacter rejection.
+- `cookbook stop` requires sessionIds matching `[a-zA-Z0-9_-]+`.
+- Agent CAN spawn GPU-pinning long-lived processes — always `cookbook stop` your previous attempt before relaunching.
+
+## Forbidden Bypass Pattern
+
+If you are about to reach the Odysseus host/container, import app internals, query the database, or call MCP helper modules directly, stop. Those paths bypass Odysseus Settings and token scopes. Ask the user to enable the relevant Codex Agent tool toggle instead.

+  2. The browser polls ``POST /api/copilot/device/poll`` with ``poll_id``.
+     While pending it returns ``{status: "pending"}``; once the user authorises
+     it provisions the endpoint and returns ``{status: "authorized", ...}``.
