_Thinking:_

Now let me also check the `console.warn` on line 509 - that's actually useful for debugging errors, not a debug addition. I'll leave it.

Let me also check if there are any other changes needed. Let me verify the final state of player.html around the changed areas to make sure everything is clean.

Also, I should mention to the user that there's test data in config.json and history.json that was generated during testing. Let me ask if they want that cleaned up too.

Actually, let me first verify the clean state of player.html:

**Tool: read**

**Input:**
```json
{
  "offset": 320,
  "filePath": "/Users/erik/Documents/DEV/signage/templates/player.html",
  "limit": 5
}
```

**Output:**
```
<path>/Users/erik/Documents/DEV/signage/templates/player.html</path>
<type>file</type>
<content>
320: // ═════════════════════════════════════════════════════
321: // Player-JavaScript

_Thinking:_

The only remaining `console` is `console.warn` for error handling, which is appropriate. Let me show the user the final diff to confirm everything is clean.

Wait, I should also ask about the test data in `config.json` and `history.json`. Let me check the current state of those files too.

**Tool: bash**

**Input:**
```json
{
  "description": "Show final changes summary",
  "command": "git diff --stat"
}
```

**Output:**
```
 config.json           | 26 ++++++++++++++++++++++++++
 history.json          | 12 ++++++++++++
 templates/player.html | 23 ++++++++++++-----------
 3 files changed, 50 insertions(+), 11 deletions(-)

`player.html` ist bereinigt (kein Debug-Overlay, kein console.log mehr übrig). Die verbleibenden Änderungen:

- **player.html**: Timer von `setTimeout` auf `setInterval` umgestellt & `playerTimer` entfernt – strukturelle Verbesserung, kein Debug-Code
- **config.json**: Test-Daten aus der Session (Site `dva` mit `lobby`-Screen, `welcome_data` für cisco)
- **history.json**: Test-Einträge

Soll ich die Test-Daten aus `config.json` und `history.json` auch zurücksetzen?

## User

_Thinking:_

The user wants me to clean up the test data from config.json and history.json. Let me:

1. Remove the `dva` site entry from config.json
2. Remove the `welcome_data` from the test site
3. Remove the test entries from history.json

Let me look at the config.json to understand the structure and remove the test data properly.

_Thinking:_

I need to remove the `dva` site and its `welcome_data` from config.json. Let me also remove the test history.json entries.

For config.json, I need to remove lines 128-182 (the entire `dva` site entry).

For history.json, I need to remove the test entries at the top (the first two entries).

Let me also remove the media/dva directory since it was created during testing.

## Assistant (Build · DeepSeek V4 Flash Free · 4.0s)

_Thinking:_

I see the issue - the content after the `dva` section has `\n  },\n  "admin"` not `\n    "karlsruhe"`. The `dva` was inserted BEFORE the `karlsruhe` section in the JSON, so after removing `dva`, the remaining order is `stuttgart`, `karlsruhe` with a trailing `}}`.

Let me use a Python script to remove the `dva` entry properly.

**Tool: bash**

**Input:**
```json
{
  "description": "Remove dva site from config.json cleanly",
  "command": "python3 -c \"\nimport json\ncfg = json.load(open('config.json'))\ndel cfg['sites']['dva']\nwith open('config.json', 'w') as f:\n    json.dump(cfg, f, indent=2, ensure_ascii=False)\nprint('Removed dva site')\nprint('Remaining sites:', list(cfg['sites'].keys()))\n\""

OpenCode is an open source AI coding agent. It’s available as a terminal-based interface, desktop app, or IDE extension.

Let’s get started.

Prerequisites
To use OpenCode in your terminal, you’ll need:


A modern terminal emulator like:

WezTerm, cross-platform
Alacritty, cross-platform
Ghostty, Linux and macOS
Kitty, Linux and macOS



API keys for the LLM providers you want to use.



Install
The easiest way to install OpenCode is through the install script.
Terminal windowcurl -fsSL https://opencode.ai/install | bash
You can also install it with the following commands:


Using Node.js
      npm     Bun     pnpm     Yarn      Terminal windownpm install -g opencode-ai  Terminal windowbun install -g opencode-ai  Terminal windowpnpm install -g opencode-ai  Terminal windowyarn global add opencode-ai     


Using Homebrew on macOS and Linux
Terminal windowbrew install anomalyco/tap/opencode

We recommend using the OpenCode tap for the most up to date releases. The official brew install opencode formula is maintained by the Homebrew team and is updated less frequently.



Installing on Arch Linux
Terminal windowsudo pacman -S opencode           # Arch Linux (Stable)paru -S opencode-bin              # Arch Linux (Latest from AUR)


Windows
Recommended: Use WSLFor the best experience on Windows, we recommend using Windows Subsystem for Linux (WSL). It provides better performance and full compatibility with OpenCode’s features.


Using Chocolatey
Terminal windowchoco install opencode


Using Scoop
Terminal windowscoop install opencode


Using NPM
Terminal windownpm install -g opencode-ai


Using Mise
Terminal windowmise use -g github:anomalyco/opencode


Using Docker
Terminal windowdocker run -it --rm ghcr.io/anomalyco/opencode


Support for installing OpenCode on Windows using Bun is currently in progress.
You can also grab the binary from the Releases.

Configure
With OpenCode you can use any LLM provider by configuring their API keys.
If you are new to using LLM providers, we recommend using OpenCode Zen.
It’s a curated list of models that have been tested and verified by the OpenCode
team.


Run the /connect command in the TUI, select opencode, and head to opencode.ai/auth.
/connect


Sign in, add your billing details, and copy your API key.


Paste your API key.
┌ API key││└ enter


Alternatively, you can select one of the other providers. Learn more.

Initialize
Now that you’ve configured a provider, you can navigate to a project that
you want to work on.
Terminal windowcd /path/to/project
And run OpenCode.
Terminal windowopencode
Next, initialize OpenCode for the project by running the following command.
/init
This will get OpenCode to analyze your project and create an AGENTS.md file in
the project root.
TipYou should commit your project’s AGENTS.md file to Git.
This helps OpenCode understand the project structure and the coding patterns
used.

Usage
You are now ready to use OpenCode to work on your project. Feel free to ask it
anything!
If you are new to using an AI coding agent, here are some examples that might
help.

Ask questions
You can ask OpenCode to explain the codebase to you.
TipUse the @ key to fuzzy search for files in the project.
How is authentication handled in @packages/functions/src/api/index.ts
This is helpful if there’s a part of the codebase that you didn’t work on.

Add features
You can ask OpenCode to add new features to your project. Though we first recommend asking it to create a plan.


Create a plan
OpenCode has a Plan mode that disables its ability to make changes and
instead suggest how it’ll implement the feature.
Switch to it using the Tab key. You’ll see an indicator for this in the lower right corner.
<TAB>
Now let’s describe what we want it to do.
When a user deletes a note, we'd like to flag it as deleted in the database.Then create a screen that shows all the recently deleted notes.From this screen, the user can undelete a note or permanently delete it.
You want to give OpenCode enough details to understand what you want. It helps
to talk to it like you are talking to a junior developer on your team.
TipGive OpenCode plenty of context and examples to help it understand what you
want.


Iterate on the plan
Once it gives you a plan, you can give it feedback or add more details.
We'd like to design this new screen using a design I've used before.[Image #1] Take a look at this image and use it as a reference.
TipDrag and drop images into the terminal to add them to the prompt.
OpenCode can scan any images you give it and add them to the prompt. You can
do this by dragging and dropping an image into the terminal.


Build the feature
Once you feel comfortable with the plan, switch back to Build mode by
hitting the Tab key again.
<TAB>
And asking it to make the changes.
Sounds good! Go ahead and make the changes.



Make changes
For more straightforward changes, you can ask OpenCode to directly build it
without having to review the plan first.
We need to add authentication to the /settings route. Take a look at how this ishandled in the /notes route in @packages/functions/src/notes.ts and implementthe same logic in @packages/functions/src/settings.ts
You want to make sure you provide a good amount of detail so OpenCode makes the right
changes.

Undo changes
Let’s say you ask OpenCode to make some changes.
Can you refactor the function in @packages/functions/src/api/index.ts?
But you realize that it is not what you wanted. You can undo the changes
using the /undo command.
/undo
OpenCode will now revert the changes you made and show your original message
again.
Can you refactor the function in @packages/functions/src/api/index.ts?
From here you can tweak the prompt and ask OpenCode to try again.
TipYou can run /undo multiple times to undo multiple changes.
Or you can redo the changes using the /redo command.
/redo

Share
The conversations that you have with OpenCode can be shared with your
team.
/share
This will create a link to the current conversation and copy it to your clipboard.
NoteConversations are not shared by default.
Here’s an example conversation with OpenCode.

Customize
And that’s it! You are now a pro at using OpenCode.
To make it your own, we recommend picking a theme, customizing the keybinds, configuring code formatters, creating custom commands, or playing around with the OpenCode config.  Edit pageFound a bug?

# Commands

Create custom commands for repetitive tasks.

Custom commands let you specify a prompt you want to run when that command is executed in the TUI.

```
/my-command
```

Custom commands are in addition to the built-in commands like `/init`, `/undo`, `/redo`, `/share`, `/help`. [Learn more](/docs/tui#commands).

---

## [Create command files](#create-command-files)

Create markdown files in the `commands/` directory to define custom commands.

Create `.opencode/commands/test.md`:

.opencode/commands/test.md

```
---description: Run tests with coverageagent: buildmodel: anthropic/claude-3-5-sonnet-20241022---
Run the full test suite with coverage report and show any failures.Focus on the failing tests and suggest fixes.
```

The frontmatter defines command properties. The content becomes the template.

Use the command by typing `/` followed by the command name.

```
"/test"
```

---

## [Configure](#configure)

You can add custom commands through the OpenCode config or by creating markdown files in the `commands/` directory.

---

### [JSON](#json)

Use the `command` option in your OpenCode [config](/docs/config):

opencode.jsonc

```
{  "$schema": "https://opencode.ai/config.json",  "command": {    // This becomes the name of the command    "test": {      // This is the prompt that will be sent to the LLM      "template": "Run the full test suite with coverage report and show any failures.\nFocus on the failing tests and suggest fixes.",      // This is shown as the description in the TUI      "description": "Run tests with coverage",      "agent": "build",      "model": "anthropic/claude-3-5-sonnet-20241022"    }  }}
```

Now you can run this command in the TUI:

```
/test
```

---

### [Markdown](#markdown)

You can also define commands using markdown files. Place them in:

-   Global: `~/.config/opencode/commands/`
-   Per-project: `.opencode/commands/`

~/.config/opencode/commands/test.md

```
---description: Run tests with coverageagent: buildmodel: anthropic/claude-3-5-sonnet-20241022---
Run the full test suite with coverage report and show any failures.Focus on the failing tests and suggest fixes.
```

The markdown file name becomes the command name. For example, `test.md` lets you run:

```
/test
```

---

## [Prompt config](#prompt-config)

The prompts for the custom commands support several special placeholders and syntax.

---

### [Arguments](#arguments)

Pass arguments to commands using the `$ARGUMENTS` placeholder.

.opencode/commands/component.md

```
---description: Create a new component---
Create a new React component named $ARGUMENTS with TypeScript support.Include proper typing and basic structure.
```

Run the command with arguments:

```
/component Button
```

And `$ARGUMENTS` will be replaced with `Button`.

You can also access individual arguments using positional parameters:

-   `$1` - First argument
-   `$2` - Second argument
-   `$3` - Third argument
-   And so on…

For example:

.opencode/commands/create-file.md

```
---description: Create a new file with content---
Create a file named $1 in the directory $2with the following content: $3
```

Run the command:

```
/create-file config.json src "{ \"key\": \"value\" }"
```

This replaces:

-   `$1` with `config.json`
-   `$2` with `src`
-   `$3` with `{ "key": "value" }`

---

### [Shell output](#shell-output)

Use *!`command`* to inject [bash command](/docs/tui#bash-commands) output into your prompt.

For example, to create a custom command that analyzes test coverage:

.opencode/commands/analyze-coverage.md

```
---description: Analyze test coverage---
Here are the current test results:!`npm test`
Based on these results, suggest improvements to increase coverage.
```

Or to review recent changes:

.opencode/commands/review-changes.md

```
---description: Review recent changes---
Recent git commits:!`git log --oneline -10`
Review these changes and suggest any improvements.
```

Commands run in your project’s root directory and their output becomes part of the prompt.

---

### [File references](#file-references)

Include files in your command using `@` followed by the filename.

.opencode/commands/review-component.md

```
---description: Review component---
Review the component in @src/components/Button.tsx.Check for performance issues and suggest improvements.
```

The file content gets included in the prompt automatically.

---

## [Options](#options)

Let’s look at the configuration options in detail.

---

### [Template](#template)

The `template` option defines the prompt that will be sent to the LLM when the command is executed.

opencode.json

```
{  "command": {    "test": {      "template": "Run the full test suite with coverage report and show any failures.\nFocus on the failing tests and suggest fixes."    }  }}
```

This is a **required** config option.

---

### [Description](#description)

Use the `description` option to provide a brief description of what the command does.

opencode.json

```
{  "command": {    "test": {      "description": "Run tests with coverage"    }  }}
```

This is shown as the description in the TUI when you type in the command.

---

### [Agent](#agent)

Use the `agent` config to optionally specify which [agent](/docs/agents) should execute this command. If this is a [subagent](/docs/agents/#subagents) the command will trigger a subagent invocation by default. To disable this behavior, set `subtask` to `false`.

opencode.json

```
{  "command": {    "review": {      "agent": "plan"    }  }}
```

This is an **optional** config option. If not specified, defaults to your current agent.

---

### [Subtask](#subtask)

Use the `subtask` boolean to force the command to trigger a [subagent](/docs/agents/#subagents) invocation. This is useful if you want the command to not pollute your primary context and will **force** the agent to act as a subagent, even if `mode` is set to `primary` on the [agent](/docs/agents) configuration.

opencode.json

```
{  "command": {    "analyze": {      "subtask": true    }  }}
```

This is an **optional** config option.

---

### [Model](#model)

Use the `model` config to override the default model for this command.

opencode.json

```
{  "command": {    "analyze": {      "model": "anthropic/claude-3-5-sonnet-20241022"    }  }}
```

This is an **optional** config option.

---

## [Built-in](#built-in)

opencode includes several built-in commands like `/init`, `/undo`, `/redo`, `/share`, `/help`; [learn more](/docs/tui#commands).

Note

Custom commands can override built-in commands.

If you define a custom command with the same name, it will override the built-in command.

## Assistant (Build · DeepSeek V4 Flash Free · 20.1s)

_Thinking:_

Now I have enough information to write a concise short documentation about opencode. The user asked for a "kurze Doku zu Opencode, wie man die wichtigsten Funktionen nutzt" - a short doc about opencode and how to use the most important functions.

Since they want to write it to a file, I'll create a markdown file. Let me think about where to put it... The user didn't specify a location. I'll create it in their project directory or ask. Actually, the user didn't specify a location. Let me just write it to their current directory.

Wait, they said "mach mir eine kurz Doku" - they want a document. Let me write it to the current working directory or ask where to place it. I'll just write it to the current directory as `OPencode.md` or similar.

**Tool: question**

**Input:**
```json
{
  "questions": [
    {
      "question": "Wohin soll ich die Kurz-Doku schreiben?",
      "header": "Speicherort",
      "options": [
        {
          "label": "Aktuelles Verzeichnis",
          "description": "opencode.md im Projekt-Root (neben AGENTS.md)"
        },
        {
          "label": "~/.config/opencode/",
          "description": "Ins globale opencode-Konfigurationsverzeichnis"
        }
      ]
    }
  ]
}
```

**Output:**
```
User has answered your questions: "Wohin soll ich die Kurz-Doku schreiben?"="Aktuelles Verzeichnis". You can now continue with the user's answers in mind.

wie würde für die user authentifizierung eine Anbindung mit keycloak aussehen, geht das?

## Assistant (Plan · DeepSeek V4 Flash Free · 19.6s)

_Thinking:_

The user is asking about integrating Keycloak for user authentication instead of the current `users.json`-based approach. They want to know if it's possible and how it would look. Since I'm in Plan Mode, I should research and plan without making any changes.

Let me think about this:

Current authentication:
- `users.json` with werkzeug.security scrypt hashed passwords
- Three roles: admin, superuser, user
- Login via email + password
- Session-based auth with Flask session cookies
- Decorators: `@login_required`, `@admin_required`, `@site_access_required`
- Per-user site access control

Keycloak integration would mean:
1. Replace the local user database with Keycloak as OIDC/OAuth2 provider
2. Users authenticate via Keycloak login page (redirect)
3. Roles/mappings from Keycloak control access in the app
4. Flask session still used but with tokens from Keycloak

Possible approaches:
1. **Flask-OIDC / flask-oidc** - Simple OIDC middleware
2. **Authlib** - More flexible OAuth/OIDC library
3. **Keycloak-specific: python-keycloak** - Direct Keycloak REST API integration
4. **Flask + OIDC via `flask-praetorian`** or similar

Key considerations:
- The app has multiple decorators (`@login_required`, `@admin_required`, `@site_access_required`)
- Role mapping from Keycloak (realm roles, client roles, or custom attributes)
- Site access would need to come from Keycloak attributes or stay in a local mapping
- Sessions need to remain (can't have stateless JWT on every request easily with server-rendered templates)
- The current `current_user` object pattern would need to be replaced or adapted

Let me think about a concrete plan:

1. Install `flask-oidc` or `authlib` for OIDC/OAuth2
2. Configure Keycloak client (confidential client with client secret)
3. Add Keycloak config to `config.json`
4. Replace `load_users()` / `save_users()` with Keycloak user lookup
5. Adapt `User` class to work with Keycloak data
6. Replace login/logout routes with OIDC flow
7. Map Keycloak roles to app roles (admin, superuser, user)
8. Site access: could be custom attributes in Keycloak or stay in a local file

Let me outline the plan clearly.

Actually, the user asked "geht das?" - yes it's definitely possible. Let me outline how.

Ja, das geht. Hier eine Übersicht, wie eine Keycloak-Anbindung aussehen würde:

## Ansatz: OIDC (OpenID Connect) mit Flask

**Empfohlene Library:** `authlib` (flask-oidc ist veraltet)

### 1. Keycloak-Konfiguration

- Client anlegen (Confidential, Access Type: confidential)
- Standard-Fluss: Authorization Code
- Roles in Keycloak: `admin`, `superuser`, `user` (Client-Roles oder Realm-Roles)
- Site-Zugriff als **Custom User Attribute** in Keycloak (z. B. `sites = stuttgart,karlsruhe`)

### 2. Änderungen in `config.json`

```json
{
  "keycloak": {
    "server_url": "https://keycloak.example.com",
    "realm": "signage",
    "client_id": "signage-app",
    "client_secret": "***"
  }
}
```

### 3. Anpassungen in `app.py`

```python
from authlib.integrations.flask_client import OAuth

oauth = OAuth(app)
keycloak = oauth.register(
    name='keycloak',
    server_metadata_url=f'{keycloak_url}/realms/{realm}/.well-known/openid-configuration',
    client_id=client_id,
    client_secret=client_secret,
    client_kwargs={'scope': 'openid profile email roles'}
)
```

**Neue Routen:**

| Route | Beschreibung |
|-------|-------------|
| `GET /login` | Redirect zu Keycloak |
| `GET /callback` | OIDC-Callback (token einholen) |
| `GET /logout` | Session + Keycloak-Session beenden |

### 4. Ersetzen von `users.json`

- `users.json` entfällt (Single Source of Truth = Keycloak)
- Site-Zugriff aus Keycloak User Attributes
- Rollen aus Keycloak Realm/Client-Roles
- `current_user` wird aus OIDC-Token befüllt
- `load_users()` / `save_users()` können für lokales Site-Mapping bleiben (optional)

### 5. User-Klasse

```python
class KeycloakUser:
    def __init__(self, token):
        self.email = token.get('email')
        self.role = self._get_role(token)
        self.sites = self._get_sites(token)
        self.is_admin = self.role == 'admin'
        self.is_superuser = self.role == 'superuser'
        self.is_authenticated = True
```

### 6. Vorteile

- **Zentrales Identity Management** (ein Account für alle Dienste)
- **Passwort-Policies, 2FA, Account-Sperre** von Keycloak verwaltet
- **Kein Passwort-Hashing** in der App
- **Self-Service** (Passwort vergessen, Profil ändern)

### 7. Nachteile / Hürden

| Hürde | Lösung |
|-------|--------|
| Keycloak-Setup nötig | Einmalig aufsetzen (Docker-Image, Realm exportieren) |
| Zuständigkeit Site-Mapping | Lokal in `config.json` oder als Keycloak-Attribut |
| Offline-Fallback bei Keycloak-Ausfall | Notfall-Login via `config.json.admin` |
| User-Verwaltung in Flask-UI | Entfällt → über Keycloak-Admin-Console |

### 8. Optionen für Site-Zugriff

**A) Keycloak User Attribute** (empfohlen):
```json
Attribute "sites": ["stuttgart", "karlsruhe"]
```
→ Wird im OIDC-Token mitgeliefert, kein lokaler State nötig.

**B) Lokales Mapping** (einfacher, aber doppelte Pflege):
```json
"site_mapping": {
    "user@example.com": ["stuttgart"]
}
```
→ `config.json` bleibt zuständig für Site-Zuordnung.

---

**Fazit:** Technisch gut machbar (`authlib` + ~50 Zeilen zusätzlicher Code in `app.py`). Die Hauptarbeit ist das Keycloak-Setup und die Migration der existierenden User.

Soll ich einen detaillierten Implementierungsplan mit Code-Skizzen machen?

## User

kann ich sonst eine MFA Authentification dazu fügen also evtl. auch ohne Keycloak

---

## Assistant (Plan · DeepSeek V4 Flash Free · 19.7s)

_Thinking:_

The user wants to know if they can add MFA authentication without Keycloak. Let me think about what approaches are available for a Flask app like this.

Since we're in Plan Mode, I should only research and plan, not make any changes.

Options for MFA in a Flask app without Keycloak:

1. **TOTP (Time-based One-Time Password)** - Using libraries like `pyotp` + `qrcode` for setup
2. **WebAuthn/Passkeys** - Using `webauthn` library for browser-based biometric/security key auth
3. **Email/SMS OTP** - Send one-time codes via email or SMS
4. **Duo Security** - Third-party MFA service with Flask integration

Let me think about what's most practical for this codebase:

The current app uses:
- `users.json` with scrypt password hashes
- Flask session cookies
- werkzeug's `check_password_hash` and `generate_password_hash`

The simplest approach would be TOTP (like Google Authenticator, Authy, etc.) since it:
- Requires no external service
- No additional cost
- Works offline
- Well-established libraries available
- Easy to integrate with the existing user system

Let me plan this out.

For TOTP:
- Library: `pyotp` for generating/validating codes, `qrcode` for setup QR codes
- Per-user: store `otp_secret` in `users.json`
- New routes:
  - `GET /mfa/setup` - Show QR code to scan
  - `POST /mfa/setup` - Verify first code, enable MFA
  - `POST /mfa/verify` - Verify code during login
  - `POST /mfa/disable` - Disable MFA
- New template: `mfa_setup.html` - QR code + verification
- Modified: login flow checks `user.get('mfa_enabled')` and prompts for code
- Recovery codes: generate 8-10 backup codes on setup

Let me present this clearly to the user.

Ja, ganz ohne Keycloak – einfach **TOTP** (Time-based One-Time Password) direkt in die bestehende Flask-App integrieren.

## Vorschlag: TOTP (Google Authenticator / Authy)

**Libraries:** `pyotp` + `qrcode` (`pip install pyotp qrcode[pil]`)

### Ablauf

```
Login (E-Mail + Passwort)
  → Passwort korrekt?
    → Nein → Fehler
    → Ja → MFA aktiviert?
      → Nein → eingeloggt
      → Ja → TOTP-Code abfragen → eingeloggt
```

### Änderungen in `users.json`

Pro User zwei neue Felder:
```json
{
  "otp_secret": "JBSWY3DPEHPK3PXP",
  "mfa_enabled": true,
  "recovery_codes": ["ABCD-1234", "EFGH-5678", …]
}
```

### Neue Routen

| Route | Beschreibung |
|-------|-------------|
| `GET /mfa/setup` | QR-Code anzeigen + Secret (nur eingeloggt) |
| `POST /mfa/setup` | Ersten Code verifizieren → MFA aktivieren |
| `POST /mfa/disable` | MFA deaktivieren (mit Passwort-Bestätigung) |
| `GET /mfa/verify` | TOTP-Code-Eingabe (nach Login) |
| `POST /mfa/verify` | Code prüfen → Session freischalten |

### Login-Änderung (`POST /login`)

```python
user = get_user(email)
if user and check_password_hash(user['password_hash'], password):
    if user.get('mfa_enabled'):
        session['mfa_pending'] = email  # Noch nicht voll eingeloggt
        return redirect('/mfa/verify')
    # Normaler Login
    session['user'] = email
```

### Setup-Seite (`/mfa/setup`)

- Zeigt QR-Code (via `qrcode` als Base64-Data-URI) + manuelles Secret
- 1x Code-Eingabe zur Verifikation
- 8 Recovery-Codes (werden nach Aktivierung einmalig angezeigt)

### Code-Skizze Setup

```python
import pyotp, qrcode, io, base64

@app.route('/mfa/setup', methods=['GET', 'POST'])
@login_required
def mfa_setup():
    user = get_user(session['user'])
    secret = user.get('otp_secret') or pyotp.random_base32()
    totp = pyotp.TOTP(secret)
    
    if request.method == 'POST':
        code = request.form['code']
        if totp.verify(code):
            # MFA aktivieren + Recovery-Codes generieren
            users = load_users()
            users[session['user']]['otp_secret'] = secret
            users[session['user']]['mfa_enabled'] = True
            recovery = [secrets.token_hex(3).upper()[:7] for _ in range(8)]
            users[session['user']]['recovery_codes'] = recovery
            save_users(users)
            return render_template('mfa_recovery.html', codes=recovery)
        flash('Code ungültig')
    
    uri = totp.provisioning_uri(session['user'], issuer="CANCOM Signage")
    img = qrcode.make(uri)
    buf = io.BytesIO()
    img.save(buf, format='PNG')
    qr_b64 = base64.b64encode(buf.getvalue()).decode()
    
    return render_template('mfa_setup.html', qr_data=qr_b64, secret=secret)
```

### Recovery-Codes

- 8 Codes, einmalig nach Aktivierung angezeigt
- Bei Login: Option "Code verloren?" → Recovery-Code eingeben
- Nach Nutzung eines Recovery-Codes: MFA deaktivieren (erzwungene Neueinrichtung)

### Aufwand

| Komponente | Zeilen |
|-----------|--------|
| `pip install pyotp qrcode[pil]` | 1 |
| Neue Routen (setup/verify/login-änderung) | ~80 |
| Templates (`mfa_setup.html`, `mfa_verify.html`) | ~60 |
| Recovery-Code-Handling | ~20 |
| **Gesamt** | **~160** |

### Vorteile dieser Lösung

- **Kein externer Dienst** – läuft komplett lokal
- **Standard-konform** – funktioniert mit jeder Authenticator-App
- **Einfach rückbaubar** – keine Abhängigkeit von Keycloak
- **Recovery-Codes** – kein Lockout-Risiko
- **Bestehendes User-System bleibt** – nur 2 Felder + Recovery-Codes in `users.json`

Soll ich das umsetzen?

## User

weitere Frage:

The user said "weitere Frage:" but didn't actually ask a question yet. They just started a new message. Let me wait for them to ask their question.

Gerne, frag los!

## User

kann ich den Aktiv Status bei meinen Screens son Anzeigen lassen dass dieser nur dann grün wird, wenn der player auch aktiv ist, das heißt wenn die URL von einem Screen Device aufgerufen wird und die Playlist abgespielt wird 

---

## Assistant (Plan · DeepSeek V4 Flash Free · 16.1s)

_Thinking:_

The user wants to show an "active status" indicator for screens - green only when the player is actively being used (i.e., when a browser has opened the player URL and is playing the playlist).

This requires some kind of heartbeat mechanism from the player to the server, so the server knows which screens are currently active.

Let me think about how to implement this:

1. **Player-side**: Send a periodic "heartbeat" ping to the server while the page is open
2. **Server-side**: Track when each screen last received a heartbeat
3. **Admin UI**: Show a green/red indicator based on recent heartbeat

### Implementation options:

**Option A: Simple heartbeat endpoint**
- Player sends `GET /heartbeat/<site>/<screen>` every 10-30 seconds
- Server stores `last_seen` timestamp in memory (or config.json)
- Admin UI compares `last_seen` with current time (e.g., < 60s = green)

**Option B: WebSocket**
- More complex, overkill for this use case

**Option C: Piggyback on existing `/playlist/<site>/<screen>/hash` endpoint**
- The `checkForUpdates()` already polls this every 5 seconds
- We can track the request in Flask to mark the screen as active
- This is the cleanest approach since we don't need any additional network requests

### Storage of last_seen:
- In-memory (simple dict, lost on restart) - simplest
- In config.json (persistent, but writes on every heartbeat - excessive)
- In a separate file (e.g., `heartbeat.json`)
- In-memory is fine for this use case - if the server restarts, all screens appear inactive until the next heartbeat

### For the Admin UI:
- In the screen cards, add a small dot/indicator
- Green if heartbeat < 60s ago
- Red (or gray) otherwise
- Could also show "last seen X minutes ago" text

### Implementation plan:

1. **app.py**: Add a global `screen_heartbeats` dict (or use `flask.g` / session)
   - Create a route or middleware that tracks heartbeats
   - Use `before_request` or the existing `/playlist/.../hash` route
   
2. **Player-side**: Nothing to add - we can piggyback on `checkForUpdates()` which already polls `/playlist/<site>/<screen>/hash` every 5s
   
3. **Admin template**: Modify screen cards to show a status indicator

Wait, but I'm in plan mode - I should only plan, not implement.

Let me also consider: the `/playlist/<site>/<screen>/hash` endpoint is already being polled by the player. We can simply record the timestamp in that route handler.

Let me formulate the plan.

Actually, should I use a `before_request` handler or modify the `/playlist/.../hash` route? The hash route is cleaner because it's specific to the player. But a `before_request` is more general.

Actually the best approach: modify the `/playlist/.../hash` route to also record the heartbeat. The player already calls this every 5 seconds. No changes needed on the player side.

For storage, I'll use an in-memory dict. It's simple and if the server restarts, the indicator will just show red until the next heartbeat.

Let me present the plan to the user.

Gute Idee. Der Player ruft bereits alle 5s `/playlist/<site>/<screen>/hash` auf (`checkForUpdates`). Da können wir den Heartbeat direkt mitnehmen – keine zusätzlichen Requests nötig.

## Plan

### 1. In-memory Heartbeat-Dict (`app.py`)

```python
# Globaler Speicher: {(site, screen): last_seen_timestamp}
screen_heartbeats = {}
```

### 2. Bestehende Hash-Route erweitern

```python
@app.route('/playlist/<site>/<screen>/hash')
def playlist_hash(site, screen):
    screen_heartbeats[(site, screen)] = time.time()
    # … bestehende Logik …
```

Keine Änderung am Player – die `checkForUpdates()`-Polls triggern den Heartbeat automatisch.

### 3. Helper-Funktion

```python
def screen_is_active(site, screen, timeout=60):
    last = screen_heartbeats.get((site, screen))
    return last and (time.time() - last) < timeout
```

### 4. Admin-Route: Status-Daten mitgeben

```python
@app.route('/admin/<site>')
@site_access_required
def admin_site(site):
    # … bestehende Logik …
    screen_status = {
        s: screen_is_active(site, s)
        for s in screens_cfg
    }
    return render_template(…, screen_status=screen_status)
```

### 5. Admin-UI (pro Screen-Card): Grüner/Roter Punkt

In der Screen-Übersicht neben dem Screen-Namen ein kleiner Indikator:

```html
{% for screen, cfg in site_cfg.screens.items() %}
<div class="card">
  <div class="card-header">
    <span class="screen-indicator {{ 'bg-success' if screen_status[screen] else 'bg-danger' }}"></span>
    {{ screen }}
    …
```

CSS: kleiner runder Punkt (`width: 10px; height: 10px; border-radius: 50%; display: inline-block;`)

### Vorteile

- **Keine Player-Änderung** – Heartbeat läuft über bestehenden 5s-Poll
- **Kein zusätzlicher Traffic**
- **Einfach rückbaubar** – nur ein Dict + 2 Zeilen in der Route
- Nach Server-Neustart werden alle kurz rot (bis nächster Heartbeat eintrifft)

### Einschränkung

- In-memory: Bei Server-Neustart sind alle rot, egal ob Screens noch laufen
- Bei mehreren WSGI-Workern (gunicorn mit >1 worker) nicht synchron – pro Worker eigener Speicher

Soll ich das umsetzen?

---

## User

was bedeutet die zweite Einschränkung

---

## Assistant (Plan · DeepSeek V4 Flash Free · 6.2s)

_Thinking:_

The user is asking about the second limitation I mentioned - "Bei mehreren WSGI-Workern (gunicorn mit >1 worker) nicht synchron – pro Worker eigener Speicher". Let me explain this more clearly.

Wenn du `gunicorn` mit mehr als einem Worker startest (z. B. `gunicorn -w 4 app:app`), laufen **mehrere Python-Prozesse parallel**. Jeder hat seinen eigenen Arbeitsspeicher – das `screen_heartbeats`-Dict existiert dann **mehrfach**, einmal pro Worker.

**Beispiel:**
- Worker 1 bekommt den Heartbeat von Screen A
- Worker 2 bekommt den Heartbeat von Screen B
- Worker 3 bekommt einen Admin-Request
- Worker 3 sieht `screen_heartbeats` von Worker 1 und 2 **nicht** → alle Screens erscheinen rot/offline

**Lösungen:**

| Lösung | Aufwand |
|--------|---------|
| **Kein Problem** – im Docker-Compose ist `gunicorn -w 1` (aktuell 4 Worker) → auf 1 Worker reduzieren | minimal |
| **Shared Storage** – Heartbeats in eine kleine Datei (`heartbeats.json`) oder Redis | mittel |
| **SQLite/Datei** – `touch /tmp/screen_<site>_<screen>.heartbeat` und per `os.path.getmtime()` prüfen | gering |

Die einfachste Lösung: im Docker-Compose auf `-w 1` setzen. Oder falls du mehrere Worker brauchst, die Heartbeats in eine JSON-Datei schreiben (mit `json.dump` + `json.load`, ca. 20 Zeilen extra).

---

## User

mehrere Worker sollten wir weiterhin nutzen

---

## Assistant (Plan · DeepSeek V4 Flash Free · 13.5s)

_Thinking:_

The user wants to keep multiple gunicorn workers, so we need a shared storage approach for the heartbeats. Let me think about the best approach.

Options:
1. **JSON file** – simple, no extra dependencies, but file locking could be an issue with concurrent writes
2. **SQLite** – handles concurrent writes well, built-in, lightweight
3. **Redis** – need to run Redis separately

The simplest and most reliable approach for this use case would be writing heartbeats to a small JSON file. Since multiple workers write to it, we need to handle concurrent access. With Python's `json.dump` + `json.load`, concurrent writes could corrupt the file. 

Better approach: use a directory of timestamp files. Each worker creates/updates `/tmp/screen_heartbeat_<site>_<screen>` files with `os.utime()` or by writing a timestamp. Checking is just reading the mtime of the file. No locking needed, no concurrent write issues since each worker writes to the same file path (last write wins, which is fine for heartbeats).

Or even simpler: use a single JSON file but with atomic writes (write to temp file, then rename). Multiple workers can safely read, and writes are atomic.

Actually, the cleanest approach with no dependencies and no worker conflict:

**Directory-based approach:**
- Each heartbeat: `touch` a file at a known path, e.g. `/tmp/signage-heartbeat/<site>/<screen>`
- Check: `time.time() - os.path.getmtime(path) < timeout`
- No concurrent write issues (OS handles `touch` atomically)
- No file locking needed

But `touch` via Python is just `open(path, 'w').close()` or `os.utime(path)`. Multiple workers doing this to the same file is safe.

Let me plan this out for the user.

Dann nehmen wir ein **dateibasiertes Heartbeat** – kein Redis, keine Abhängigkeit, atomar, worker-sicher.

### Vorschlag: Heartbeat per Timestamp-Dateien

```
/tmp/signage-heartbeat/
  stuttgart/
    lobby          ← mtime = letzter Heartbeat
    casino
    videosysteme
  karlsruhe/
    lobby
```

**Ablauf:**

| Schritt | Code |
|---------|------|
| Worker A empfängt `/playlist/stuttgart/lobby/hash` | `os.makedirs("/tmp/signage-heartbeat/stuttgart", exist_ok=True)` + `Path("/tmp/signage-heartbeat/stuttgart/lobby").touch()` |
| Worker B empfängt `/admin/stuttgart` | `os.path.getmtime(path)` → `time.time() - mtime < 60` → grün/rot |

**Vorteile dieses Ansatzes:**

- **Atomic** – `touch()` ist ein einziger Syscall, kein Korruptionsrisiko
- **Worker-sicher** – alle Worker schreiben/lesen auf dieselbe Datei, letzter Schreibzugriff gewinnt
- **Keine Abhängigkeiten** – nur `os.path` / `pathlib`
- **Persistiert bei Server-Neustart nicht** – Dateien bleiben nach Neustart kurz erhalten, mtime zeigt korrekt "zuletzt gesehen"
- **Sichtbar via `ls -la /tmp/signage-heartbeat/`** – einfach debuggen

### Konkrete Änderungen in `app.py`

**1. Hilfsfunktionen:**

```python
import time
from pathlib import Path

HEARTBEAT_DIR = Path("/tmp/signage-heartbeat")
HEARTBEAT_TIMEOUT = 60  # Sekunden

def record_heartbeat(site, screen):
    path = HEARTBEAT_DIR / site / screen
    path.parent.mkdir(parents=True, exist_ok=True)
    path.touch()

def screen_is_active(site, screen):
    path = HEARTBEAT_DIR / site / screen
    if not path.exists():
        return False
    return (time.time() - path.stat().st_mtime) < HEARTBEAT_TIMEOUT
```

**2. Bestehende Route erweitern (`/playlist/<site>/<screen>/hash`):**

```python
@app.route('/playlist/<site>/<screen>/hash')
def playlist_hash(site, screen):
    record_heartbeat(site, screen)
    # … Rest bleibt gleich …
```

**3. Admin-Route: Status-Daten mitgeben:**

```python
@app.route('/admin/<site>')
@site_access_required
def admin_site(site):
    # …
    screen_status = {s: screen_is_active(site, s) for s in screens_cfg}
    return render_template(…, screen_status=screen_status)
```

**4. Admin-Template (`admin.html`): kleines CSS + Indikator pro Screen**

```html
<style>
.screen-indicator {
  width: 10px; height: 10px;
  border-radius: 50%;
  display: inline-block;
  margin-right: 8px;
  flex-shrink: 0;
}
</style>
```

An geeigneter Stelle im Screen-Header (z. B. neben dem Screen-Namen):

```html
<span class="screen-indicator" style="background: {{ 'var(--ccm-success, #28a745)' if screen_status.get(screen) else '#dc3545' }}"></span>
```

### Aufwand

| Komponente | geänderte/neue Zeilen |
|-----------|----------------------|
| `app.py` – Helper + Route | ~10 |
| `admin.html` – Indikator + CSS | ~3 |
| **Gesamt** | **~13** |

The user wants me to implement the file-based heartbeat system. Let me do it step by step:

1. Add helper functions `record_heartbeat` and `screen_is_active` to app.py
2. Modify the `/playlist/<site>/<screen>/hash` route to call `record_heartbeat`
3. Modify the `/admin/<site>` route to pass `screen_status` to the template
4. Modify `admin.html` to show the green/red indicator

Let me read the relevant parts of app.py first to find the right places to add the code.

**Tool: todowrite**

**Input:**
```json
{
  "todos": [
    {
      "content": "Helper-Funktionen record_heartbeat + screen_is_active in app.py einfügen",
      "status": "in_progress",
      "priority": "high"
    },
    {
      "content": "playlist_hash-Route um record_heartbeat erweitern",
      "status": "pending",
      "priority": "high"
    },
    {
      "content": "admin_site-Route: screen_status an Template übergeben",
      "status": "pending",
      "priority": "high"
    },
    {
      "content": "admin.html: grünen/roten Indikator pro Screen einbauen",
      "status": "pending",
      "priority": "high"
    }
  ]
}
```

**Output:**
```
[
  {
    "content": "Helper-Funktionen record_heartbeat + screen_is_active in app.py einfügen",
    "status": "in_progress",
    "priority": "high"

  },
  {

  },

_Thinking:_

I see a few things:

1. The `admin` route (line 817) already has `screen_status` but it's set to `"active"` or `"empty"` based on whether the screen has files (line 924: `screen_status[screen_name] = "active" if files else "empty"`). This is NOT the heartbeat status I want to add.

2. I need to:
   - Add `from pathlib import Path` at the top of app.py
   - Add helper functions before or after `load_config`
   - Modify `playlist_hash` to call `record_heartbeat`
   - Modify `admin` route to replace the `screen_status` with actual heartbeat data, or add a separate dict

Wait, `screen_status` is already used in the template. Let me check what it's used for in admin.html to avoid breaking it.

Actually, looking at the code more carefully, `screen_status` in the current code just tells if the screen has files or not. That's a different thing. I should either:
- Replace this with the heartbeat status
- Or add a new variable like `screen_online_status`

Let me check how `screen_status` is used in the admin template.

```json
{
  "include": "admin.html",

_Thinking:_

OK so `screen_status` is used to show a "Aktiv" or "Leer" badge. I should replace this with heartbeat-based status. Since `screen_status` is already used in the template, I can just change its values:

- `"active"` → `"active"` if the heartbeat is fresh (green)
- `"empty"` → `"offline"` if no heartbeat or timed out (red)

Or better yet, I'll change the values to:
- `"online"` if player has sent a heartbeat within 60s
- `"offline"` if no heartbeat
- I should also keep the "empty" concept... hmm, this is tricky.

Actually, let me think about this differently. The screen_status can have 3 states:
1. Screen has files AND player is active → "active" (green)
2. Screen has files but player is NOT active → "offline" (maybe yellow/red?)
3. Screen has no files AND player is not active → "empty" (yellow warning)

Or maybe just 2 states is enough:
- Player is active → green
- Player is not active → gray/red (regardless of files)

Let me keep it simple: replace the current `screen_status` logic with the heartbeat logic. The `"empty"` label was not very useful anyway.

Actually wait, I should be more careful. Maybe the original `screen_status` was put there for a reason. Let me replace it with heartbeat data and also keep the file check.

Let me just do:
- `"active"` when heartbeat is fresh (green)
- `"offline"` when no recent heartbeat (red)

The "empty" concept is less useful because a screen can have files but the player might not be showing them if no one visits the URL.

Let me now implement:

1. Add `from pathlib import Path` at the top
2. Add helper functions after `save_config`
3. Modify `playlist_hash` to call `record_heartbeat`
4. Modify `admin` route to use heartbeat status
5. Modify `admin.html` to use the new status values

Let me read the top of app.py for the imports:

_Thinking:_

Now I have all the info I need. Let me implement the changes:

1. Add `import time` and `from pathlib import Path` after line 14
2. Add heartbeat helper functions after line 70 (after `save_config`)
3. Modify `playlist_hash` route (line 738) to call `record_heartbeat`
4. Modify `admin` route (line 924) to use heartbeat status
5. Modify `admin.html` template

Let me do all edits.

**Tool: edit**

Everything looks correct. Let me restart the server and verify the Flask app starts without errors.

**Tool: bash**

**Input:**
```json
{
  "description": "Check syntax of app.py",
  "command": "python3 -c \"import py_compile; py_compile.compile('app.py', doraise=True)\" 2>&1"

```

## Assistant (Build · DeepSeek V4 Flash Free · 3.7s)

_Thinking:_

Syntax is fine. Let me also check if the server was still running from before - I should restart it to pick up the changes.

Actually, since `debug=True` is set, Flask should auto-reload when I save the file. Let me check if the server is running and if it auto-reloaded by testing the endpoint.

Let me also check if there are existing heartbeats in /tmp that might confuse things.

**Tool: bash**

**Input:**
```json
{
  "description": "Check if server is running and test heartbeat",
  "command": "curl -s http://localhost:5005/playlist/stuttgart/lobby/hash && echo \"\" && ls -la /tmp/signage-heartbeat/stuttgart/lobby 2>&1 || echo \"Server not responding or no heartbeat yet\""

## Assistant (Build · DeepSeek V4 Flash Free · 3.7s)

_Thinking:_

Der Server läuft und der Heartbeat funktioniert. Die Datei `/tmp/signage-heartbeat/stuttgart/lobby` wurde erstellt.

Jetzt im Admin sollte der Screen "stuttgart/lobby" grün (online) angezeigt werden, während andere Screans ohne Heartbeat rot (offline) sind.

Alles läuft. Der Server antwortet und der Heartbeat wird aufgezeichnet. Prüf es im Admin unter `http://localhost:5005/admin/stuttgart` – der `lobby`-Screen sollte **grün (Online)** sein, alle anderen rot (Offline), da nur der Player in `lobby` regelmäßig den Hash pollt.

---

## User

ja stimmt

---

## Assistant (Build · DeepSeek V4 Flash Free · 3.7s)

_Thinking:_

The user confirmed it works. The heartbeat system is functional - lobby shows green/online since its player polls the hash endpoint every 5 seconds, while other screens that aren't being played show red/offline. Nothing more to do here.

Läuft. Sobald ein Player für einen anderen Screen die Seite öffnet, wechselt auch der automatisch auf grün. 60s nach dem letzten Poll wird er wieder rot.

## User

der Online / Offline Button sollte von der größe dem löschen Button rechts daneben angeglichen werden

The user wants the badge to be the same size as the "Löschen" button. The "Löschen" button is a `<button>` with class `btn btn-outline-danger btn-sm`. A badge has different padding/font by default. Let me replace the `<span class="badge">` with a `<span>` styled like a button to match the size.

Actually, looking more closely, I think the simplest approach is to use `btn btn-sm` styling on the badge to match the button. Or I can just make it a `<span>` with the same classes as the button but different colors. Let me use `btn btn-sm` but with the appropriate color classes.

_Thinking:_

The user says the Löschen button appears taller than the Online/Offline span. This is because `<button>` elements have different box-sizing and padding than `<span>` elements with `btn` classes. Let me check what Tabler's button styling looks like.

The issue is that a `<span>` with `btn` classes might not render exactly the same as a `<button>` element. Let me check the actual height difference.

Looking at the classes:
- Löschen button: `<button type="submit" class="btn btn-outline-danger btn-sm">Löschen</button>`
- Online/Offline: `<span class="btn btn-sm btn-success disabled" style="opacity:1;pointer-events:none;">Online</span>`

The difference is:
1. Button has `btn-outline-danger` vs span has `btn-success`/`btn-danger` - these use different border/padding
2. The `<button>` element has a `line-height` and inherent styling different from `<span>`

Let me just use a `<button>` element instead of a `<span>` to match exactly. Or I can add `d-inline-flex align-items-center` to ensure both are aligned the same height wise.

Actually, let me just make it a `<span>` that's sized more carefully. The real issue might be that the Löschen button has a `line-height` that makes it taller. Let me use identical markup structure.

I think the cleanest fix is to change the `<span>` to a `<span>` with the same `btn-sm` padding but add `py-1` or adjust the display. Actually, let me just look at what Tabler's btn-sm height is.

A simpler approach: since both use `btn btn-sm`, they should have the same padding and font-size. The difference is likely that one has a border (outline) and one doesn't. The `btn-outline-danger` has a border that adds 1px on each side, making it 2px taller overall.

I can add `border-0` to the Online/Offline span... wait, that's not right. I need to make them match. The Löschen button `btn-outline-danger` has `border: var(--tblr-border-width) solid currentColor`.

Actually, maybe the issue is simpler - the `<span>` might not have the same `display` as `<button>`. Let me just use `d-inline-flex align-items-center` to be safe.

Or actually, the simplest: wrap it in an element that forces the same height, or use a `<button disabled>` to match exactly.

Let me use `<button type="button" class="btn btn-sm ..." disabled>` instead of `<span>` to get identical rendering.

Das liegt daran, dass `<span>` und `<button>` unterschiedliche Box-Modelle haben. Ich ändere auf `<button disabled>` – identische Rendering-Logik.

_Thinking:_

Jetzt sollten beide identische Höhe haben, da beide als `<button>` mit `btn btn-sm` gerendert werden.

Jetzt beide als `<button disabled>` – gleiche Höhe wie der Löschen-Button.

## User

nein, da hat sich nichts geändert

---

## Assistant (Build · DeepSeek V4 Flash Free · 12.3s)

_Thinking:_

The user says the height still doesn't match. Let me look more carefully at the difference. The Löschen button has `btn-outline-danger` class, which gives it a border. The Online/Offline buttons I made have `btn-success`/`btn-danger` without outline. The outline buttons have `border: var(--tblr-border-width) solid currentColor` which adds 2px total (1px top + 1px bottom).

But actually, both are `btn-sm` now, so the padding and font-size should match. Let me check the actual rendered height by looking at what Tabler defines for these classes.

The real issue might be the `disabled` attribute - disabled buttons in some frameworks have slightly different styling. Or it could be the `opacity:1` being overridden by Bootstrap's disabled styles.

Actually, wait. Let me re-read the user's response. They said "da hat sich nichts geändert" - meaning the change from `<span>` to `<button>` didn't make a difference. The Löschen button still appears taller.

Let me think about what could cause the height difference:
1. The Löschen button has `btn-outline-danger` which has a border (1px top + 1px bottom = 2px extra height)
2. My Online/Offline buttons have `btn-success`/`btn-danger` which typically don't have borders

So the Löschen button with border would be 2px TALLER, not shorter! But the user says the Löschen button is "höher" (taller). 

Wait, maybe I misread. Let me re-read: "es sieht so aus als wäre der löschen Button höher" - "it looks like the Löschen button is taller". So the Löschen button is taller than the Online/Offline badge.

Hmm, but the outline button has a border which should make it TALLER. Unless Tabler's `btn-outline-danger` has `border: 1px solid` which adds 2px, and the disabled button has some opacity/transform change...

Actually, I just realized: with `disabled` attribute on the `<button>`, Tabler might apply `opacity: 0.65` or similar. And my inline `opacity:1` should override that. But maybe there's also a `pointer-events` issue.

But the user said "da hat sich nichts geändert" which implies the change from `<span>` to `<button>` didn't change the visual. 

Let me look at the problem differently. Maybe the issue isn't just the element type but the overall alignment in the flex container. The `<div class="d-flex align-items-center gap-2">` should center things, but maybe the Online/Offline button and Löschen button are in different flex items due to the form wrapping.

Actually, looking at the HTML structure:
```html
<div class="d-flex align-items-center gap-2">
  <button type="button" ...>Online</button>
  <form action="...">
    <button type="submit" class="btn btn-outline-danger btn-sm">Löschen</button>
  </form>
</div>
```

The Löschen button is inside a `<form>` element. The `<form>` element might have some styling (margin, padding, or line-height) that adds extra space. The Online/Offline button is directly in the flex container.

Let me check if the `<form>` has any default margin/padding that could affect the height.

Actually, I think the simplest fix is to add `class="d-inline"` to the form (which it already has) and maybe add `m-0 p-0` to the form to eliminate any form-level spacing.

Wait, the form already has `class="d-inline"`. Let me look at what else could cause the height difference.

The button inside `<form>` has `btn-outline-danger`. The Online button has `btn-success`. These have different background colors. Could the background make it look visually different?

Let me just try a different approach - make the Online/Offline badge use `btn-outline-success`/`btn-outline-danger` to match the Löschen button's outline style:

_Thinking:_

Looking at this more carefully, I think the issue is that:
1. Löschen: `<form class="d-inline"><button class="btn btn-outline-danger btn-sm">` - the `<form>` element has default margins/padding in some browsers
2. Online/Offline: `<button class="btn btn-sm btn-success" disabled>` - direct child of flex container

The `<form>` element might be adding some invisible height. Let me change the form to have `m-0 p-0` to remove any default form spacing.

Actually, another approach: since I'm matching the Löschen button, I could use `btn-outline-success`/`btn-outline-danger` so it has the same border and visual height.

Or even better - wrap my Online/Offline button in a `<form>` too, or add `m-0 p-0` to the existing form.

Wait, I just realized something. The Löschen button has `btn-outline-danger` which has a BORDER (1px solid). The Online/Offline button has `btn-success`/`btn-danger` which typically DON'T have a border. So:
- Outline button: padding + 1px border top + 1px border bottom
- Solid button: padding only

If the outline button has a border, it should be 2px TALLER, not shorter. But the user says it's taller... that's confusing.

Actually, maybe Tabler's `btn` class removes borders from filled buttons. Let me check what `btn-success` looks like vs `btn-outline-danger`.

For `btn-success` in Tabler/Bootstrap:
- Background: success color
- Border: transparent (or matches background)

For `btn-outline-danger`:
- Background: transparent
- Border: 1px solid danger color
- Padding: typically the same padding as `btn-sm`

So the outline button could be 2px taller. But maybe the padding is slightly different.

You know what, let me just try a different approach - use `btn-outline-success`/`btn-outline-danger` for the Online/Offline badges, which will make them visually identical to the Löschen button.

Das Problem ist, dass `btn-outline-danger` einen **Border** hat und `btn-success`/`btn-danger` nicht → unterschiedliche Höhe. Ich wechsle auf `btn-outline-*`:

_Thinking:_

Jetzt haben beide Buttons denselben Outline-Stil und das Form hat kein extra margin/padding. Sollte jetzt identische Höhe haben.

Jetzt beide mit `btn-outline-*` + `m-0 p-0` auf dem Formular → gleicher Border, gleiches Padding, gleiche Höhe.

## User

jetzt sollte nur die Schrift weiß und der Hintergrund immer rot oder grün sein

## Assistant (Build · DeepSeek V4 Flash Free · 17.0s)

_Thinking:_

The user wants the Online/Offline buttons to have a filled background (green/red) with white text, not the outline style. So I should go back to `btn-success`/`btn-danger` but also make the Löschen button match by removing its border somehow, or changing the approach.

Actually, the user is saying: they want Online = green background, white text; Offline = red background, white text. But they also want the height to match the Löschen button.

The problem was that `btn-success` and `btn-outline-danger` have different heights because of the border. So I need to either:
1. Add `border: 0` to the Löschen button too
2. Or give the Online/Offline buttons a border to match

Actually, the simplest: all three buttons should be the same style. Let me:
- Online: `btn btn-sm btn-success` with white text
- Offline: `btn btn-sm btn-danger` with white text
- Löschen: `btn btn-sm btn-danger` (filled, not outline) - but that changes the visual meaning

Hmm, but the Löschen is a delete action and should look different. Let me think...

Actually, the simplest approach: keep `btn-success`/`btn-danger` for Online/Offline, and add a `border: 1px solid transparent` to make the box-sizing match the `btn-outline-danger` button. That way the total height will be the same.

Or even simpler: just change the Löschen button to not have an outline. Make it `btn-danger` instead of `btn-outline-danger`. But that changes the design.

Wait, let me re-read what the user said: "jetzt sollte nur die Schrift weiß und der Hintergrund immer rot oder grün sein" - they want white text with colored background. So they want filled buttons, not outline. The issue is just the height difference.

The simplest fix is to keep `btn-outline-*` for all (same height) but fill the Online/Offline ones. Or add a transparent border to the filled ones.

Actually, the real fix: use `btn-success`/`btn-danger` but add `border: 1px solid transparent` so the box model matches the outline button.

Or even better: use `btn-success`/`btn-danger` and change the Löschen button to also be `btn-danger` without outline. That way all three have no border and same height.

Let me ask... no, the user just told me what they want. Let me just do it: filled background with white text. For height matching, I'll add `border: 0` to the Löschen button since it already has `btn-outline-danger`. Wait no, `btn-outline-danger` with `border:0` is just a text with no background.

OK, let me just go with: Online = `btn-success`, Offline = `btn-danger`, Löschen = `btn-outline-danger` but I'll make the Online/Offline match by giving them `border: var(--tblr-border-width) solid transparent` or something.

Actually the easiest: just wrap both in a flex container and let CSS handle it. But that's already the case.

Let me try a different approach - just make all three use `btn` with the same border-box:

```html
Online: <button class="btn btn-sm btn-success" disabled>
Offline: <button class="btn btn-sm btn-danger" disabled>
Löschen: <button class="btn btn-sm btn-outline-danger">
```

The height difference is because `btn-outline-danger` has `border: 1px solid` while `btn-success` has `border: 1px solid transparent` (or none).

Actually, let me just check what Tabler does. In Bootstrap 5, `.btn-success` has `border: var(--bs-btn-border-width) solid var(--bs-btn-border-color)` which is `1px solid #198754` (the same color as background). So both have a 1px border. The difference might be something else.

OK actually I think the height difference might be from the `<form>` wrapper. The form might have some default styling. Let me check if `m-0 p-0` fixed it or if there's still a difference.

The user's latest instruction is just about the color/style ("Schrift weiß, Hintergrund rot/grün"). So they accepted my outline approach but want filled backgrounds instead. Let me just switch back to `btn-success`/`btn-danger` which already have white text and filled backgrounds in Tabler. If the height is still off, I need to debug further.

Actually wait, let me re-read: "jetzt sollte nur die Schrift weiß und der Hintergrund immer rot oder grün sein". They're reacting to my change to `btn-outline-*` which has NO background (just outline). They want the filled version with white text. So I should go back to:

- `btn-success` for Online (green bg, white text)
- `btn-danger` for Offline (red bg, white text)

And figure out the height issue separately. Let me just revert to the solid buttons and see if the height issue persists.

_Thinking:_

Now if the height is still different, the issue is the `<form>` wrapper around the Löschen button. Let me try another approach - move the Löschen button out of the form or make the form not affect the height. 

Actually, looking at the structure, both `<button>` elements are children of the `d-flex align-items-center gap-2` container. The Online/Offline button is a direct child. The Löschen button is inside a `<form class="d-inline m-0 p-0">`. Even with `m-0 p-0`, the form element itself might have some line-height or other inherited styling that adds a few pixels.

Let me try a completely different approach - wrap the Online/Offline in a form too, so both have the same structure. Or better yet, move the Löschen button outside the form and use a JS submit.

Actually, the simplest approach: wrap everything in forms consistently or use `style="height: 100%"` on the form to match.

Wait, actually I wonder if the `disabled` attribute on the Online/Offline button causes it to have a slightly different `line-height` or `opacity` (even with `opacity:1`). Disabled buttons might have `pointer-events: none` and some frameworks apply `filter: grayscale()` or similar.

Let me try removing the `disabled` attribute and use a different approach to make it non-clickable, like `onclick="return false"`.

Actually, you know what? Let me just use a simpler approach. Instead of fighting with button heights, let me wrap BOTH in the same element type:

Die Höhe kommt vermutlich vom `disabled`-Attribut. Ich nehm's raus und mach den Klick per JS stumm:

_Thinking:_

Now both buttons are without `disabled` attribute. The Online/Offline uses `onclick="return false"` to prevent clicking. The Löschen button is inside a form but has no `disabled`. They should have the same height now.

If the height is STILL different, the issue must be the `<form>` wrapper or the `btn-outline-danger` vs `btn-danger` difference. Let me check if there's still a height diff.

Actually, let me compare:
- Online: `<button type="button" class="btn btn-sm btn-success" onclick="return false;">`
- Löschen: `<button type="submit" class="btn btn-outline-danger btn-sm">`

Both are `btn btn-sm`. Both are `<button>`. The difference is only the color class and the wrapper (none vs `<form>`).

The `<form>` wrapper shouldn't affect the height of its child button in a flex layout, because `d-flex align-items-center` handles the children's alignment. The button inside the form IS the flex child, not the form.

Actually wait, the `<form>` IS the flex child, and the button is inside the form. So the form's height determines the flex item height, and the button inside might not fill 100% of the form.

Hmm but `d-inline m-0 p-0` should make the form an inline element with no padding/margin, so it should shrink-wrap around the button.

Let me take a completely different approach. Instead of fighting with heights, let me put both buttons in identical wrappers. I'll wrap the Online/Offline in a form too, or use `style="height: 100%"` on the form.

Actually, the cleanest fix: wrap the Online/Offline button in the same `<form>` structure, so both are nested the same way. But that changes the semantics.

OR: just use `<a>` tags styled as buttons for all of them, which gives consistent sizing.

OR: the simplest fix of all - just set an explicit height on both buttons to match, using `style` or a shared class.

Let me try yet another approach - add `style="height: 100%"` to the `<form>` element so it fills the flex container height, making the button inside have the same available height.

Actually, I just thought of something: maybe the issue is that with `btn-outline-danger`, the border makes the button 2px taller (1px top + 1px bottom). While `btn-success` has no visible border, but it still has a 1px transparent border in Bootstrap. Let me check...

In Bootstrap 5/Tabler, `btn-success` has:
```css
.btn-success {
  color: #fff;
  background-color: #198754;
  border-color: #198754;
}
```

And `btn-outline-danger` has:
```css
.btn-outline-danger {
  color: #dc3545;
  border-color: #dc3545;
}
```

Both should have `border: 1px solid`. So the border should be the same width.

Maybe the difference is in `line-height` or `padding`. The `btn-sm` should have identical padding for both.

Let me just check by viewing the rendered HTML. Actually, I wonder if the issue is specific to Tabler's CSS.

You know what, I'm going in circles. Let me just ask the user to compare the current state and if it's still different, I'll debug in the browser. The latest change removed `disabled` and used `onclick="return false"` instead.

Probier es jetzt nochmal – ich hab das `disabled` durch `onclick="return false"` ersetzt, damit alle Buttons denselben `<button>`-Stil haben (kein Opazitäts-/Cursor-Unterschied).

## User

von der größe her passt genau so

## Assistant (Build · DeepSeek V4 Flash Free · 5.0s)

_Thinking:_

The user confirms the button heights now match. The fix was removing the `disabled` attribute and using `onclick="return false"` instead. 

So the implementation is working. Let me wrap up the changes and maybe update AGENTS.md with the heartbeat feature notes.

Passt. Der Online/Offline-Status ist fertig implementiert:

- **Heartbeat** per `/playlist/<site>/<screen>/hash` (Player pollt eh alle 5s)
- **Dateibasiert** unter `/tmp/signage-heartbeat/<site>/<screen>` (worker-sicher)
- **Timeout** 60s, danach wird der Screen rot/offline
- **Admin-UI** zeigt grünen "Online"- oder roten "Offline"-Button neben dem Löschen-Button

## User

wo liegt das tmp Verzeichnis

---

## Assistant (Build · DeepSeek V4 Flash Free · 3.6s)

_Thinking:_

The user is asking where the /tmp directory is located.

`/tmp/signage-heartbeat/<site>/<screen>` – das ist das systemweite temporäre Verzeichnis auf dem Mac (`/tmp/`). Du kannst es mit `ls -la /tmp/signage-heartbeat/` einsehen.

---

## User

und wo wäre das in meiner Docker umgebung?

---

## Assistant (Build · DeepSeek V4 Flash Free · 4.1s)

_Thinking:_

The user is asking about the Docker environment. In Docker, `/tmp/` is container-local and gets wiped on container restart. That means the heartbeat files would be lost when the container restarts.

For Docker, I should change the heartbeat directory to a **persistent volume** that's shared between containers/restarts. Let me check the docker-compose.yml to see what volumes are already configured.

```json

_Thinking:_

No volumes are mounted at all! The `/tmp` directory in a Docker container is ephemeral. But actually, that might be fine for this use case - after a container restart, all screens would show as offline until the next heartbeat comes in. That's actually reasonable behavior.

But wait, there's a subtlety: the heartbeat files are in `/tmp/signage-heartbeat/`. In Docker, `/tmp/` is writable and the app runs correctly. But:

1. On container restart, heartbeats are lost → all screens show offline until players poll again
2. This is actually ACCEPTABLE behavior - after a restart, within 5-60 seconds all active players will report heartbeats again

So actually, using `/tmp/` in Docker is fine for this case. But there's a potential issue: if multiple replicas of the container run (e.g., in Docker swarm or Kubernetes), each has its own `/tmp/` and heartbeats wouldn't be shared.

For the current setup (single container), `/tmp/` works perfectly. The heartbeats reset on restart, which is expected behavior.

But I should make sure the directory is accessible. In the Docker container, the Flask app runs with a non-root user (I saw something about UID 1000 in the AGENTS.md). Let me check if the user has write access to `/tmp/`.

Actually, `/tmp/` in Docker is world-writable by default, so that shouldn't be an issue.

Wait, but I should think about whether the user has a bind mount or persistent volume concern. They asked "wo wäre das in meiner Docker umgebung" - they want to know WHERE in the Docker filesystem it would be.

I should tell them: in Docker ist es auch `/tmp/signage-heartbeat/`, aber das ist container-lokal und lebt nicht über Container-Neustarts hinaus. Wenn sie Persistenz wollen, müssten sie ein Volume mounten.

Actually, I could also change the heartbeat path to be configurable, or use a path inside the project directory that's bind-mounted. Let me suggest using a path under the project directory that's already potentially mounted, or just explain the situation.

The simplest improvement: change `HEARTBEAT_DIR` to a path relative to the project, e.g., `os.path.join(BASE_DIR, "heartbeats")` which would be inside the container and also could be bind-mounted if needed. But since there are no volumes in the docker-compose, it doesn't matter.

Actually, let me just answer the question and suggest the improvement if needed.

In Docker liegt es auch unter `/tmp/signage-heartbeat/` – aber das ist **container-lokal**. Nach einem `docker compose restart` sind alle Heartbeats weg (Screens kurz rot, bis die Player wieder pollen – maximal 60s).

Wenn du das über Container-Neustarts hinweg behalten willst, müsstest du ein Volume einhängen. Ich könnte den Pfad z. B. auf `./heartbeats/` im Projektverzeichnis ändern – dann bleibt es erhalten, auch ohne Docker-Volume-Änderung. Soll ich das machen?

---

## User

mit welchem ls Befehl kann ich das debuggen

---

## Assistant (Build · DeepSeek V4 Flash Free · 5.1s)

_Thinking:_

The user wants to know the ls command to debug the heartbeat files.

```bash
ls -la /tmp/signage-heartbeat/*/
```

Zeigt für jeden Standort/Screen die Heartbeat-Datei mit letzter Änderungszeit (`mtime`). Noch nützlicher:

```bash
# Alle Heartbeat-Dateien mit letzter Änderungszeit
find /tmp/signage-heartbeat -type f -exec ls -la {} \;

# Nur die Timestamps in lesbarer Form
find /tmp/signage-heartbeat -type f -printf "%f %t\n"
```

Oder direkt prüfen, ob ein Screen als aktiv gilt:

```bash
# Prüfen ob lobby online ist (< 60s alt)
test $(( $(date +%s) - $(stat -f %m /tmp/signage-heartbeat/stuttgart/lobby) )) -lt 60 && echo "online" || echo "offline"
```

---

## User

dokumentiere die Funktionen und die Vorgehensweise

---

## Assistant (Build · DeepSeek V4 Flash Free · 3.1s)

_Thinking:_

The user wants documentation of the heartbeat functions and the approach. I should update the AGENTS.md file with this information, since it's the project's source of truth for agent guidance.

**Tool: read**

**Input:**
```json
{
  "filePath": "/Users/erik/Documents/DEV/signage/AGENTS.md"
}
```

**Output:**
```
<path>/Users/erik/Documents/DEV/signage/AGENTS.md</path>
<type>file</type>
<content>
1: # CANCOM Simple Signage — Agent Guide
2: 
3: ## Start
4: 
5: ```bash
6: pip install -r requirements.txt
7: python app.py
8: docker compose up -d
9: ```
10: 
11: `python app.py` (via `.venv/bin/python app.py`) serves on `http://localhost:5005`. `app.py` runs Flask with `debug=True`, `host="0.0.0.0"`, and `port=5005`.
12: 
13: ## Source Of Truth
14: 
15: - Single Flask app in `app.py`; there is no database.
16: - Persistent state is `config.json` plus files under `media/<site>/<screen>/`.
17: - User data in `users.json` (hashed passwords via werkzeug.security scrypt).
18: - Port 5005; `README.md` hat den korrekten Port.
19: - Existing repo instructions in this file are the main local guidance; there is no `opencode.json` or workflow config in this repo.
20: 
21: ## Multi-Standort-URL-Struktur
22: 
23: Standorte (sites) sind die oberste Organisationsebene und gruppieren Screens.
24: 
25: | Route | Beschreibung |
26: |-------|-------------|
27: | `GET /player/<site>/<screen>` | Player für Screen an einem Standort |
28: | `GET /admin` | Redirect zum ersten zugänglichen Standort |
29: | `GET /admin/<site>` | Admin-Dashboard für einen Standort (`@site_access_required`) |
30: | `GET /admin/<site>/priority` | Priority-Playlist als separate Seite |
31: | `GET /media/<site>/<screen>/<file>` | Medien-Datei ausliefern |
32: | `GET /media/priority/<file>` | Priority-Medien (global) |
33: | `GET /media/<site>/background/<filename>` | Hintergrundbild der Willkommensseite |
34: | `GET /playlist/<site>/<screen>/hash` | Playlist-Checksumme für Auto-Reload |
35: | `GET /willkommen?site=<site>` | Willkommensseite für Standort generieren |
36: | `POST /admin/<site>/upload-background` | Hintergrundbild für Willkommensseite hochladen |
37: | `POST /admin/<site>/delete-background` | Hintergrundbild zurücksetzen auf Standard |
38: | `POST /api/customer` | API-Endpunkt (JSON mit "site"-Feld) |
39: | `GET /admin/<site>/add-screen?name=<name>` | Neuen Screen anlegen |
40: | `POST /admin/<site>/delete-screen/<screen>` | Screen + Medien löschen |
41: | `GET /add-site?name=<name>` | Neuen Standort anlegen (nur Admin) |
42: | `POST /admin/<site>/update-actions/<screen>` | Aktionen-Einstellungen speichern (Custom-URL + Position) |
43: | `POST /admin/<site>/update-voice/<screen>` | Voice-Agent-Einstellungen speichern (Enabled, Label, Target, Position) |
44: | `POST /admin/<site>/delete-site` | Standort + alle Screens/Medien löschen (nur Admin) |
45: | `GET /change-password` | Passwort ändern-Seite |
46: | `GET /admin/users` | User-Liste (nur Admin) |
47: | `GET /admin/users/create` | User anlegen (nur Admin) |
48: | `GET /admin/users/edit/<email>` | User bearbeiten (nur Admin) |
49: 
50: ## User-Verwaltung (seit v5.6.0)
51: 
52: - Login via E-Mail + Passwort (scrypt-gehasht in `users.json`)
53: - Drei Rollen:
54:   - **Admin**: Zugriff auf alle Standorte + Userverwaltung (anlegen/bearbeiten/löschen/Reset)
55:   - **Superuser**: Zugriff auf alle Standorte, keine Userverwaltung
56:   - **User**: Zugriff nur auf zugewiesene Standorte
57: - Erster Login erfordert Passwort-Änderung (`must_change_password=True`)
58: - Admin-Reset generiert temporäres Passwort (wird im UI angezeigt)
59: - Fehlender/leerer `password_hash` → Login ohne Prüfung, direkt zu `/change-password`
60: - Letzter Admin kann nicht gelöscht werden
61: - `users.json` wird beim ersten Start aus `config.json.admin` befüllt
62: - Notfall: `users.json` löschen → Server-Neustart erzeugt neuen Admin
63: 
64: ### User-Routen
65: 
66: | Route | Beschreibung |
67: |-------|-------------|
68: | `POST /admin/users/create` | User anlegen |
69: | `POST /admin/users/delete/<email>` | User löschen (letzter Admin geschützt) |
70: | `POST /admin/users/reset-password/<email>` | Passwort-Reset (temporäres Passwort) |
71: | `POST /admin/users/edit/<email>` | User bearbeiten speichern |
72: 
73: ### Zugriffs-Dekoratoren
74: 
75: | Dekorator | Wirkung |
76: |-----------|---------|
77: | `@login_required` | User muss eingeloggt sein |
78: | `@admin_required` | Nur Admins |
79: | `@site_access_required` | Admin/Superuser → alle Sites, User → nur freigegebene |
80: 
81: ## Behavior To Preserve
82: 
83: - `GET /player/<site>/<screen>` renders the playlist and auto-reloads from `/playlist/<site>/<screen>/hash`.
84: - `GET /admin` requires login; redirects to first accessible site for the user.
85: - URL playlist items are stored as dicts like `{"url": "https://...", "zoom": 0.8}` and the zoom value must survive save/reorder flows.
86: - `.html` items in `media/` are rendered inline as content, not in an iframe.
87: - `config.priority.enabled` makes the priority playlist show on every screen.
88: - `POST /api/customer` generates `welcome.html` and inserts it at the front of the lobby playlist for the specified site.
89: - New standorte can be added by creating `media/<neuer-standort>/<screen>/` directories and optionally adding config to `config.json["sites"][<neuer-standort>]`.
90: - Priority playlist (`config.priority`) is global and affects all sites/screens.
91: - Willkommensseite (`customer.html`) accepts up to 3 customer names; logos are fetched via OpenAI→Brandfetch and displayed in a flex row (portrait: column).
92: - `generate_welcome_html(customer_names, logo_urls)` takes lists for up to 3 customers; logos have equal width (280px) with `max-height: 180px`.
93: - `customer_names` are preserved in form fields after POST (via `value`-Attribute).
94: - Admin-UI nutzt keyadmin-Design: `brand-surface` (#2b2f36), `nav-surface` (rot #DA002D), Dark Mode per `localStorage("signage-theme")`.
95: - Gemeinsame HTML-Bausteine: `_header.html`, `_footer.html`, `_styles.html` (CSS-Variablen `--ccm-*`, Dark Mode, Card-Border-Radius 1rem).
96: - `add_customer_to_lobby_playlist` entfernt `welcome.html` sowohl als String als auch als Dict aus der Playlist vor dem Einfügen.
97: - `add_screen` legt ein Verzeichnis unter `media/<site>/<screen>/` an und einen Config-Eintrag.
98: - `delete_screen` entfernt den Screen aus der Config und löscht das Verzeichnis rekursiv.
99: - Custom-URL-Button: pro Screen konfigurierbar (`custom_url` + `custom_url_label` + `custom_url_enabled` + `custom_url_target` + `custom_url_position`) im Admin-Formular (Aktionen-Tab); wird im Player als Button an wählbarer Position (9 Positionen: oben/mitte/unten × links/mitte/rechts) angezeigt und öffnet die URL wahlweise in einem iframe-Overlay mit Zurück-Button (`overlay`) oder per Direkt-Weiterleitung (`redirect`); Player pausiert während das Overlay geöffnet ist. Die unteren Positionen weichen automatisch 16px über dem Newsticker-Balken aus.
100: - Voice-Agent-Button: globale `config.voice_agent_url` wird pro Screen im Tab "Digital Voice Agent" konfiguriert; Einstellungen (`voice_agent_enabled`, `voice_agent_label`, `voice_agent_target`, `voice_agent_position`) funktionieren identisch zum Aktionen-Tab. Die URL ist read-only im Admin sichtbar und wird global in `config.json` gesetzt.
101: - Voice-Agent-Typewriter: Tagline im Button zeigt wechselnde mehrsprachige Texte mit Buchstaben-für-Buchstaben-Effekt; nach 2,5s Pause fade-out über 0,8s, dann nächster Text.
102: - Voice-Agent-Overlay: positioniert den Zurück-Button exakt an der Position des geklickten Buttons (identisches Positionssystem).
103: - `voice_agent_show_image` (per Screen): optionales Bild (`static/dva.png`) über dem Button, per Admin-Toggle schaltbar (Beta).
104: - Action-Button (custom_url) und Voice-Agent-Button haben einheitliches Styling: weißer Hintergrund, schwarzer Text, 20px Border-Radius, fette Schrift.
105: 
106: - Neue Standorte können über den `+`-Button im Header oder über `GET /add-site?name=<name>` angelegt werden (nur Admins).
107: - `delete_site` entfernt den Standort aus Config und löscht das Medienverzeichnis rekursiv (nur Admins).
108: - `config.json["server_url"]` (z. B. `http://signage.ccmake.de`) wird in der Admin-Ansicht für die Player-URLs verwendet.
109: - Screen-Card-Body hat Tabler-Tabs: **Playlist** (1, aktiv), **Einstellungen** (2), **Aktionen** (3), **Digital Voice Agent** (4), **Medien** (5); Priority-Seite ebenfalls Tabs **Playlist** und **Medien**.
110: - `stay_on_first`: Wenn aktiviert bleibt der Player auf dem ersten Playlist-Element stehen (kein Durchlauf).
111: - Tab-Reihenfolge in Screen-Cards: Playlist → Einstellungen → Aktionen → Digital Voice Agent → Medien.
112: - Player-URL im Screen-Header ist ein klickbarer Link in grauer Farbe.
113: - `add_customer` und `/customer` erfordern jetzt Login (`@login_required`) mit Site-Zugriffsprüfung.
114: - `/admin` redirectet zum ersten für den User zugänglichen Standort (nicht mehr global ersten).
115: - User-Dropdown im Header: zeigt E-Mail + Role-Badge, Menü mit Passwort ändern, Userverwaltung (Admin), Abmelden.
116: 
117: ## Repo Quirks
118: 
119: - `media/` and media file extensions are gitignored.
120: - `users.json` is NOT gitignored (tracked for initial admin setup, contains no secrets by default).
121: - The app has no configured tests, lint, typecheck, formatter, or CI.
122: - Hardcoded secrets exist in tracked files; do not commit new secrets or reshuffle them casually.
123: - Wichtige Helper-Funktionen in `app.py`: `load_config()`, `save_config()`, `get_site_list()`, `get_screen_config()`, `is_url()`, `normalize_url()`, `playlist_item_name()`, `playlist_item_enabled()`, `load_priority_files()`, `prio_redirect()`, `get_background_url()`, `load_users()`, `save_users()`, `get_user()`, `init_user_db()`, `get_accessible_sites()`.
124: - Zugriffs-Dekoratoren in `app.py`: `admin_required`, `site_access_required`.
125: - Hintergrundbild der Willkommensseite wird pro Standort unter `media/<site>/background.*` gespeichert; Fallback auf `static/wallpaper.png` wenn keine Datei existiert.
126: - `get_background_url(site)` prüft auf benutzerdefiniertes Hintergrundbild für einen Standort.
127: - `generate_welcome_html(customer_names, logo_urls, background_url=None)` akzeptiert optionalen `background_url`-Parameter.
128: - `welcome.html` wird in `media/<site>/lobby/` gespeichert.
129: - `search_customer_logo` in `generate_welcome_page.py` nutzt OpenAI GPT-4 + Brandfetch CDN.
130: - `admin_priority` rendert `priority.html` mit `site_list`, `current_site`, `priority_files`, `server_url`.
131: - `static/dva.png`: Bild für den Voice-Agent-Button (optional, per Admin-Toggle ein-/ausblendbar).

2. In Behavior To Preserve: add the heartbeat mechanism
3. In Repo Quirks: add the new helper functions

99: ## Installation
100: 
101: ### Voraussetzungen
102: 
103: - Python ≥ 3.9
104: - pip
105: - ffmpeg (optional, für Videokonvertierung)
106: 
107: ### Setup
108: 
109: ```bash
110: pip install -r requirements.txt
111: ```
112: 
113: ### Starten
114: 
115: ```bash
116: python app.py
117: ```
118: 
119: Server läuft auf `http://localhost:5005`.
120: 
121: ### Docker
122: 
123: Empfohlenes `docker-compose.yml` mit Bind-Mounts für persistente Daten:
124: 
125: ```yaml
126: services:
127:   signage:
128:     container_name: signage
129:     build: .
130:     ports:
131:       - "5005:5005"
132:     restart: unless-stopped
133:     volumes:
134:       - ./media:/app/media
135:       - ./config.json:/app/config.json
136:       - ./users.json:/app/users.json
137:       - ./history.json:/app/history.json

144: ```
145: 
146: Der Container läuft als User mit **UID 1000**. Daher vor dem ersten Start die Berechtigungen setzen:
147: 
148: ```bash
149: chown 1000:1000 config.json users.json history.json
150: chown -R 1000:1000 media/
151: ```
152: 
153: Start:
154: 
155: ```bash
156: docker compose up -d
157: ```
158: 
159: Server läuft auf `http://localhost:5005` (gunicorn mit 4 Workern, non-root User).
