+# 🌲 Crumbforest Code Tour
+
+Dies ist dein "Reiseführer" durch den Code. Ziel ist es, jede Komponente zu verstehen, damit du sie als solide Basis für zukünftige Projekte nutzen kannst.
+
+## 🗺️ High-Level Architektur (Der Wald von oben)
+
+Der CrumbCore basiert auf **FastAPI** (Python) und folgt einer modularen Struktur:
+
+*   **`app/main.py`**: Der Eingang (Root). Hier startet alles.
+*   **`app/routers/`**: Die Wegweiser. Jede Datei bedient einen URL-Bereich (z.B. `/admin`, `/api`).
+*   **`app/services/`**: Die Arbeiter. Logik für RAG, Übersetzungen, Config-Loading.
+*   **`app/models/`**: Die Datenbank-Struktur (SQLAlchemy / raw SQL Schemas).
+*   **`app/templates/`**: Das Gesicht (Jinja2 HTML Templates) & Design.
+
+---
+
+## 🚀 1. Der Einstieg: `app/main.py`
+
+Hier atmet das System.
+
+### Wichtige Konzepte:
+1.  **FastAPI Instanz**: `app = FastAPI()` ist der Kern.
+2.  **Middleware**: `SessionMiddleware` (für Login-Cookies) und `CORSMiddleware` (Sicherheit).
+3.  **Template Engine**: `init_templates(app)` lädt Jinja2. Unsere `render`-Funktion injiziert automatisch User, Sprache und Flash-Nachrichten in jedes Template.
+4.  **Router Mounting**: Am Ende der Datei werden die Module aus `routers/` eingebunden (`app.include_router(...)`). Das hält `main.py` schlank.
+
+### Code-Lupe:
+```python
+# app/main.py
+
+# ... Imports ...
+
+# Security Secret (wichtig für Cookies!)
+SECRET = os.getenv("APP_SECRET", "dev-secret-change-me")
+
+app = FastAPI()
+
+# 1. Statische Dateien (CSS, Bilder) verfügbar machen
+app.mount("/static", StaticFiles(directory="static"), name="static")
+
+# 2. Session Middleware (Das Gedächtnis des Browsers)
+app.add_middleware(SessionMiddleware, secret_key=SECRET, ...)
+
+# 3. Template Renderer (Unsere "View Engine")
+def init_templates(app: FastAPI):
+    # ... lädt "templates"-Ordner ...
+    # Definiert die "render"-Funktion, die wir überall nutzen
+    def render(req: Request, template: str, **ctx):
+        # ... Logik für Sprache (lang) und User-Context ...
+        return HTMLResponse(tpl.render(**base_ctx))
+
+# 4. Router einbinden (Modularisierung)
+app.include_router(home_router, prefix="/{lang}") # Multi-Language Support!
+# ...
+```
+
+---
+
+## 🚦 2. Das Routing: `app/routers/`
+
+Hier entscheidet sich, wohin die Reise geht.
+
+*   **`home.py`**: Öffentliche Seiten (`/`, `/about`, `/crew`). Lädt Inhalte multiligual.
+*   **`crumbforest_roles.py`**: Das Herzstück Phase 1. Zeigt Rollen-Dashboard und Chat. Prüft `user_group`-Zugriff.
+*   **`auth.py`** (bzw. Login in Hauptdatei/Home): Verwaltet Login/Logout.
+*   **`diary_rag.py`**: API für das Tagebuch-RAG (Vector Search).
+
+---
+
+## 🧠 3. Die Intelligenz: `app/services/`
+
+*   **`rag_service.py`**: Verbindet Qdrant (Vektordatenbank) mit LLMs. Hier passiert die Magie ("Suche Igel im Wald").
+*   **`localization.py`**: Lädt `characters.de.json` usw. und merget sie live in die Config.
+
+---
+
+## 💾 4. Die Daten: `crumbforest_config.json`
+
+Unsere "Single Source of Truth" für Rollen und Gruppen.
+Statt Hardcoding in Python definieren wir hier:
+*   Wer darf was sehen? (`group_access`)
+*   Welche Farbe hat der Fuchs?
+*   Welches LLM nutzt die Eule?
+
+---
+
+Dies ist der Startpunkt. Welchen Bereich wollen wir als nächstes zerlegen? 🧐
+
+## 🧠 5. Deep Dive: Der RAG Service (`app/services/rag_service.py`)
+
+Hier wird Text zu Wissen. Wenn wir "Wald" sagen, müssen wir nicht nur Keyword-Matches finden, sondern *Bedeutung*.
+
+### Der Indexing-Workflow (`index_post`)
+Wie kommt ein Blogpost oder Tagebucheintrag in das Gehirn?
+
+1.  **Hash-Check**: Wir erstellen einen MD5-Hash des Inhalts. Ist er gleich wie in der DB? Überspringen! (Spart KI-Kosten).
+2.  **Chunking**: Der Text wird mit `EmbeddingService` in Häppchen geteilt (z.B. 1000 Zeichen).
+3.  **Embedding**: Jedes Häppchen wird durch ein Embedding-Modell (OpenAI/Jina) geschickt. Das Ergebnis ist ein Vektor (eine Liste von Zahlen, z.B. `[0.1, -0.5, ...]`).
+4.  **Upsert in Qdrant**: Wir speichern den Vektor + Metadaten (Textinhalt, Titel, Slug) in Qdrant.
+5.  **Tracking**: In MariaDB (`post_vectors` Tabelle) merken wir uns, welcher Post welche Vektoren hat (für Löschung/Updates).
+
+### Die Suche (`query_with_rag`)
+Der magische Moment, wenn der User eine Frage stellt:
+
+1.  **Embed Query**: Die Frage "Wer wohnt im Wald?" wird ebenfalls in einen Vektor verwandelt.
+2.  **Vektor-Suche (Semantic Search)**: Wir fragen Qdrant: "Welche Vektoren liegen in der Nähe dieses Frage-Vektors?". Dank Cosine-Similarity findet er Inhalte, die *inhaltlich* passen, auch ohne exakte Worte.
+3.  **Context Assembly**: Wir nehmen die Top-3 gefundenen Text-Chunks und kleben sie zusammen.
+4.  **LLM Generation**: Wir bauen einen Prompt für die KI:
+    ```text
+    Context: [Der Igel wohnt im Unterholz...]
+    Frage: Wer wohnt im Wald?
+    Antworte basierend auf dem Context.
+    ```
+5.  **Antwort**: Die KI generiert die fertige Antwort.
+
+### Warum `rag_service.py` wichtig ist
+Er entkoppelt die Logik:
+*   Der *Router* (`diary_rag.py`) weiß nur: "Indexiere dies" oder "Frage das".
+*   Der *Service* kümmert sich um die Details (Qdrant API, Datenbank-Sync, Hash-Prüfung).
+So bleibt der Controller sauber! 🧹✨
+
+## 🔐 6. Deep Dive: Sicherheit & Auth (`app/deps.py`)
+
+Wie unterscheiden wir Freund von Feind? Das "Dependency Injection" System von FastAPI regelt das elegant.
+
+### Der Wächter: `current_user`
+In `app/deps.py` definieren wir Funktionen, die FastAPI *vor* jedem Request ausführt.
+
+```python
+# app/deps.py
+
+def current_user(req: Request):
+    # Holt das User-Objekt aus dem signierten Session-Cookie
+    return req.session.get("user")
+
+def admin_required(user = Depends(current_user)):
+    # 1. Ist ein User da?
+    if not user:
+        raise HTTPException(status_code=401) # -> Login Page
+    
+    # 2. Ist es ein Admin?
+    if user.get("role") != "admin":
+        raise HTTPException(status_code=403) # -> Verboten!
+    
+    return user
+```
+
+### Die Anwendung in Routern
+Wir müssen Sicherheitschecks nicht in jede Funktion kopieren. Wir "injizieren" sie einfach:
+
+```python
+# app/routers/admin.py
+
+@router.get("/")
+def admin_dashboard(
+    user: dict = Depends(admin_required) # <--- Hier passiert der Check!
+):
+    # Wenn wir hier sind, IST der User garantiert ein Admin.
+    return render(..., user=user)
+```
+
+### Session Security (in `main.py`)
+Das Login-System basiert auf `SessionMiddleware`.
+*   **Cookie**: Der Browser bekommt ein Cookie namens `session`.
+*   **Signierung**: Das Cookie ist mit `APP_SECRET` kryptografisch signiert. Der User kann den Inhalt lesen (Base64), aber **nicht verändern**. Wenn er `role: admin` reinschummelt, wird die Signatur ungültig und der Server ignoriert das Cookie.
+*   **HttpOnly**: JavaScript kann das Cookie nicht stehlen.
+*   **SameSite**: Schützt vor CSRF-Attacken.
+
+## 🎨 7. Das Frontend (`app/templates/`)
+
+Wir nutzen **Jinja2** (klassisches Server-Side Rendering) gepaart mit **PicoCSS** (minimalistisches CSS Framework).
+
+### Struktur
+*   **`base.html`**: Das Skelett. Enthält `<head>`, Navigation und Footer. Alle anderen Seiten erben hiervon (`{% extends "base.html" %}`).
+*   **`crumbforest/`**: Templates für die Rollen-Ansicht und den Chat.
+*   **`pages/`**: Allgemeine Seiten (Login, Home).
+
+### Datenfluss
+Wenn ein Router `render(req, "login.html", error="Falsches PW")` aufruft:
+1.  Jinja2 lädt `login.html`.
+2.  Es sieht `{% extends "base.html" %}` und lädt erst das Skelett.
+3.  Es füllt die Blöcke (`{% block content %}`) mit dem Login-Formular.
+4.  Es injiziert die Variable `error` an der passenden Stelle.
+
+## 💾 8. Die Daten (`app/models/` & SQL)
+
+Hier wird es interessant. Wir nutzen **Hybrid-Ansatz**:
+
+### API-Validierung (Pydantic)
+In `app/models/` liegen Klassen wie `QueryRequest` oder `User`.
+Das sind **keine** Datenbank-Tabellen! Sie dienen nur der **Validierung** von Input/Output.
+Wenn jemand JSON an die API schickt, prüft FastAPI automatisch: "Fehlt das Feld 'question'? Ist 'limit' eine Zahl?".
+
+### Datenbank (Raw SQL)
+Wir nutzen *kein* schwergewichtiges ORM (wie SQLAlchemy) für die Queries, sondern rohes SQL via `pymysql`.
+Warum? **Performance & Kontrolle**.
+*   Zu sehen in: `app/services/rag_service.py` oder `main.py`.
+*   Codeschnipsel:
+    ```python
+    cur.execute("SELECT * FROM users WHERE email=%s", (email,))
+    ```
+Das macht den Code extrem transparent. SQL ist die Wahrheit.
+
+---
+
+🎉 **Herzlichen Glückwunsch!** Du hast den Wald einmal durchquert.
+Du kennst jetzt:
+1.  Den Einstieg (`main.py`)
+2.  Die Logik (`routers` & `services`)
+3.  Die Sicherheit (`deps.py`)
+4.  Das Gesicht (`templates`)
+5.  Das Gedächtnis (`models` & SQL)
+
+Bereit für Phase 2? 🚀
