+Dieses Dokument dient als technischer Leitfaden und Kontextdokument für KI-Coding-Agenten (sowie Entwickler), die an `mirror-package` arbeiten.

 ## 1. Projektübersicht & Philosophie

-Dieses Repository ist ein **Rust-Projekt-Template** für Linux-Anwendungen und CLI-Tools mit Fokus auf:
- Automatisierte Multi-Architektur-Kompilierung (`x86_64`, `aarch64`, `i686`).
- Native Paketierung für Debian (`.deb`), Fedora/RHEL (`.rpm`) und Arch Linux (`.pkg.tar.zst`).
- Vollständig automatisierte CI/CD-Pipelines via Gitea Actions (kompatibel mit Forgejo / GitHub Actions).
+`mirror-package` ist eine Rust-basierte CLI-Anwendung zur automatisierten Synchronisation und Spiegelung von Linux-Paketen aus GitHub-Releases in selbstgehostete Gitea/Forgejo-Paket-Registries.
+
+### Kernfunktionen & Routing
+- **Unterstützte Paketformate**: Debian (`.deb`), Fedora/RHEL (`.rpm`), Arch Linux (`.pkg.tar.zst`, `.pkg.tar.xz`, `.pkg.tar.gz`, `.pacman`).
+- **Distributions-Routing**:
+  - Stabile Releases: `.deb` wird in `pool/stable/main` **und** `pool/testing/main` geladen; `.rpm` nach `rpm/stable`; Arch nach `arch/stable`.
+  - Pre-Releases: `.deb` wird ausschließlich nach `pool/testing/main` geladen; `.rpm` nach `rpm/testing`; Arch nach `arch/testing`.
+- **Konfigurationsverwaltung**: Typensichere Speicherung über `config-ctdra`.
+- **Authentifizierung**: Tokenloser Zugriff auf öffentliche GitHub-Releases (optionaler Token konfigurierbar); Gitea-Token/URL/Owner via CLI, Env-Vars oder Config.

 ### Standards & Tech-Stack
 - **Sprache**: Rust (Edition 2024), Python 3 (für Hilfsskripte in `scripts/`).
 - **Rust Toolchain**: Stable.
 - **Zielplattform**: Linux (GLIBC-basiert, Cross-Kompilierung für `x86_64-unknown-linux-gnu`, `aarch64-unknown-linux-gnu`, `i686-unknown-linux-gnu`).
- **Lizenz**: GPL-3.0-or-later (sofern nicht im abgeleiteten Projekt anders definiert).
+- **Lizenz**: GPL-3.0-or-later.

 - **Idiomatisches Rust**: Nutze moderne Sprachfeatures der Rust Edition 2024.
- **Fehlerbehandlung**: Verwende aussagekräftige Fehlertypen (z. B. mit `thiserror` oder `anyhow` für CLIs). Vermeide unnötiges `unwrap()` oder `panic!()` im Produktivcode.
- **Kommentare**: Ergänze KDoc/RustDoc-Kommentare (`///`) an öffentlichen Funktionen und Typen. Behalte die bestehende Sprachkonvention bei.
- **Template-TODOs**: Wenn neue Vorlagen-Features oder Platzhalter ergänzt werden, markiere anpassungsbedürftige Stellen eindeutig mit `// TODO:` (Rust), `# TODO:` (TOML/Python/YAML).

-Ein modernes Template-Projekt für Rust-basierte Linux-Anwendungen und Kommandozeilen-Tools (CLI).
+# mirror-package

-Dieses Template bietet eine vorkonfigurierte Umgebung für modernes Rust (Edition 2024), automatisierte Multi-Architektur-Kompilierung und native Paketierung für die gängigsten Linux-Distributionen (Debian/Ubuntu, Fedora/RHEL, Arch Linux) sowie vollständige CI/CD-Pipelines für Gitea Actions (kompatibel mit Forgejo und GitHub Actions).
+Automatisiertes Werkzeug zum Extrahieren, Herunterladen und Spiegeln vorkompilierter Linux-Pakete aus GitHub-Releases in eine selbstgehostete Gitea- / Forgejo-Paket-Registry.
+
+`mirror-package` überwacht konfigurierte GitHub-Repositories (wie z. B. `raspberrypi/rpi-imager` oder `Heroic-Games-Launcher/HeroicGamesLauncher`), identifiziert vorkompilierte Linux-Pakete (`.deb`, `.rpm`, `.pkg.tar.zst`, `.pkg.tar.xz`, `.pkg.tar.gz`, `.pacman`) und veröffentlicht diese anhand von Release-Stabilitätsregeln automatisch in den passenden Distributionen der Gitea-Paket-Registry.

-## Features
+## Funktionen

- **Rust Edition 2024**: Moderner Rust-Sprachstandard.
- **Multi-Architektur-Kompilierung**:
-  - `x86_64-unknown-linux-gnu` (64-Bit x86)
-  - `aarch64-unknown-linux-gnu` (64-Bit ARM / ARM64)
-  - `i686-unknown-linux-gnu` (32-Bit x86)
- **Linux-Paketierung out-of-the-box**:
-  - **Debian / Ubuntu** (`.deb` via `cargo-deb`)
-  - **Fedora / RHEL / openSUSE** (`.rpm` via `cargo-generate-rpm`)
-  - **Arch Linux** (`.pkg.tar.zst` via mitgeliefertem `scripts/package-arch.py`)
- **Automatisierte CI/CD-Pipelines**:
-  - `main`-Branch: Erstellt stabile Builds, ermittelt dynamisch Build-Nummern, paketiert für alle Architekturen, lädt Pakete in die Gitea Package Registry und erstellt Gitea Releases mit Dateianhängen.
-  - `testing`-Branch: Erstellt Preview-Builds und Pre-Releases mit Testing-Paketen.
- **Automatisierte Versions- & Build-Nummern**:
-  - `scripts/get-build-number.py` fragt Gitea Releases, die Package Registry sowie lokale Artefakte ab, um Revisions-/Release-Nummern (z. B. `1.0.0-1`, `1.0.0-2`) automatisch zu erhöhen.
- **Vorkonfigurierte Cargo-Einstellungen**:
-  - `.cargo/config.toml` mit vorkonfigurierten Cross-Compilation-Linkern und Unterstützung für private/öffentliche Cargo Registries.
+- **Unterstützung mehrerer Distributionen**:
+  - **Debian / Ubuntu** (`.deb`)
+  - **Fedora / RHEL / openSUSE** (`.rpm`)
+  - **Arch Linux** (`.pkg.tar.zst`, `.pkg.tar.xz`, `.pkg.tar.gz`, `.pacman`)
+- **Distributions-Routing-Regeln**:
+  - **Stabile Releases**: Debian-Pakete werden **sowohl** im `stable`- als auch im `testing`-Debian-Pool veröffentlicht (`pool/stable/main` und `pool/testing/main`); RPM-Pakete unter `rpm/stable`; Arch-Pakete unter `arch/stable`.
+  - **Pre-Releases**: Werden **ausschließlich** in Testing-Kanälen veröffentlicht: Debian `pool/testing/main`, RPM `rpm/testing` und Arch `arch/testing`.
+- **Persistente Konfiguration über `config-ctdra`**:
+  - Speichert Einstellungen automatisch im Benutzerpfad (`~/.config/mirror-package/config.toml`) oder Systempfad (`/etc/mirror-package/config.toml`).
+  - Das Hinzufügen oder Entfernen von Repositories über die CLI aktualisiert automatisch die Konfigurationsdatei.
+- **Flexible Authentifizierung**:
+  - GitHub-Releases können anonym abgefragt werden (kein Token erforderlich).
+  - Optionale Unterstützung für GitHub Personal Access Tokens zur Vermeidung von API-Rate-Limits.
+  - Gitea-Instanz-URL, API-Token und Registry-Owner können per CLI-Flags, Umgebungsvariablen oder Konfigurationsdatei festgelegt werden.
+- **Diagnose & Dry-Run-Modus**:
+  - Einheitliches Datei- und Konsolen-Logging über `logger-ctdra`.
+  - `--dry-run`-Flag zur Simulation von Download- und Upload-Schritten ohne Änderungen an Remote-Systemen vorzunehmen.

 ---

-## Struktur des Repositories
+## CLI-Verwendung & Befehle
+
+### 1. Konfiguration (`config`)
+Richte deine Gitea-Zugangsdaten und das optionale GitHub-Token ein:
+
+```bash
+# Gitea-Instanz und Registry-Owner konfigurieren
+mirror-package config set \
+  --gitea-url "https://gitea.creative-dragonslayer.de" \
+  --gitea-token "dein_gitea_api_token" \
+  --registry-owner "Linuxapps"
+
+# Optional: GitHub-Token für höhere API-Rate-Limits konfigurieren
+mirror-package config set --github-token "ghp_xxxxxxxxxxxx"
+
+# Aktuelle Konfiguration anzeigen
+mirror-package config show
+```
+
+Zugangsdaten können auch über Umgebungsvariablen (`GITEA_URL`, `GITEA_TOKEN`, `REGISTRY_OWNER`, `GITHUB_TOKEN`) oder globale CLI-Argumente übergeben werden.
+
+### 2. Überwachte Repositories verwalten (`add`, `remove`, `list`)
+
+```bash
+# Repositories zur persistenten Konfiguration hinzufügen
+mirror-package add raspberrypi/rpi-imager
+mirror-package add Heroic-Games-Launcher/HeroicGamesLauncher
+
+# Repository ohne Synchronisierung von Pre-Releases hinzufügen
+mirror-package add some-owner/some-repo --no-prereleases
+
+# Konfigurierte Repositories und deren Sync-Status auflisten
+mirror-package list
+
+# Ein Repository entfernen
+mirror-package remove raspberrypi/rpi-imager
+```
+
+### 3. Pakete synchronisieren (`sync`)
+
+```bash
+# Alle konfigurierten Repositories synchronisieren (neueste stabile Version und neuestes Pre-Release)
+mirror-package sync
+
+# Ein bestimmtes Repository synchronisieren
+mirror-package sync raspberrypi/rpi-imager
+
+# Alle historischen Releases eines Repositories synchronisieren
+mirror-package sync raspberrypi/rpi-imager --history
+
+# Dry-Run-Test (Simulation ohne Upload)
+mirror-package sync --dry-run
+```
+
+---
+
+## Docker & Container-Nutzung
+
+`mirror-package` wird als minimales, gehärtetes Container-Image in der Gitea Container Registry bereitgestellt.
+
+### 1. Image-Registry & Tagging-Strategie
+
+- **Stabile Releases (`main`-Branch)**:
+  - `<registry>/<owner>/mirror-package:latest`
+  - `<registry>/<owner>/mirror-package:<version>`
+  - `<registry>/<owner>/mirror-package:v<version>`
+  - `<registry>/<owner>/mirror-package:<version>.<build_number>`
+- **Testing- & Vorschau-Releases (`testing`-Branch)**:
+  - `<registry>/<owner>/mirror-package:testing`
+  - `<registry>/<owner>/mirror-package:<version>-preview`
+  - `<registry>/<owner>/mirror-package:<version>-testing`
+  - `<registry>/<owner>/mirror-package:<version>-preview.<build_number>`
+  - `<registry>/<owner>/mirror-package:testing-<build_number>`
+  - *(Hinweis: Der Tag `:latest` ist strikt dem stabilen `main`-Workflow vorbehalten).*
+
+### 2. Persistente Speicherpfade
+
+Um Konfigurationen, Status und Protokolle über Container-Neustarts hinweg beizubehalten, binde folgende Pfade an Host-Verzeichnisse oder Docker-Volumes:
+
+| Container-Pfad                              | Zweck                                                 | Empfohlener Mount-Typ              |
+|---------------------------------------------|-------------------------------------------------------|------------------------------------|
+| `/home/appuser/.config/mirror-package`      | Speichert `config.toml` (Zugangsdaten & Repo-Liste)   | Host-Verzeichnis / Volume (rw)     |
+| `/home/appuser/.local/state/mirror-package` | Persistente Anwendungsprotokolle & Statusdateien      | Host-Verzeichnis / Volume (rw)     |
+| `/tmp`                                      | Download- & Streaming-Puffer für Paketdateien         | `tmpfs` (RAM / tempfs, rw, noexec) |
+
+### 3. Sicherheitshärtung
+
+Der Container wurde nach höchsten Sicherheitsstandards aufgebaut:
+- **Unprivilegierter Benutzer**: Läuft als `appuser` (UID `10001`, GID `10001`), niemals als `root`.
+- **Read-Only Root-Dateisystem**: Voll funktionsfähig mit `--read-only` / `read_only: true`.
+- **Keine Capabilities**: Sämtliche Linux-Capabilities können sicher entzogen werden (`--cap-drop=ALL`).
+- **Keine Rechteausweitung**: Erzwingt `no-new-privileges:true`.
+- **Minimale Image-Größe**: Basiert auf Debian Trixie Slim und enthält nur CA-Zertifikate und notwendige dynamische Bibliotheken (~40 MB).
+
+### 4. Ausführung über Docker CLI
+
+```bash
+# Zugangsdaten initialisieren / konfigurieren
+docker run --rm \
+  --name mirror-package \
+  --read-only \
+  --cap-drop=ALL \
+  --security-opt=no-new-privileges:true \
+  --tmpfs /tmp:rw,noexec,nosuid,size=2G \
+  -v "./config:/home/appuser/.config/mirror-package" \
+  -v "./state:/home/appuser/.local/state/mirror-package" \
+  gitea.creative-dragonslayer.de/linuxapps/mirror-package:latest \
+  config set \
+    --gitea-url "https://gitea.creative-dragonslayer.de" \
+    --gitea-token "dein_token" \
+    --registry-owner "Linuxapps"
+
+# Repositories hinzufügen
+docker run --rm \
+  --read-only \
+  --cap-drop=ALL \
+  --security-opt=no-new-privileges:true \
+  --tmpfs /tmp:rw,noexec,nosuid,size=2G \
+  -v "./config:/home/appuser/.config/mirror-package" \
+  -v "./state:/home/appuser/.local/state/mirror-package" \
+  gitea.creative-dragonslayer.de/linuxapps/mirror-package:latest \
+  add raspberrypi/rpi-imager
+
+# Synchronisation ausführen (kann über Cronjob oder Scheduler auf dem Host getriggert werden)
+docker run --rm \
+  --read-only \
+  --cap-drop=ALL \
+  --security-opt=no-new-privileges:true \
+  --tmpfs /tmp:rw,noexec,nosuid,size=2G \
+  -v "./config:/home/appuser/.config/mirror-package" \
+  -v "./state:/home/appuser/.local/state/mirror-package" \
+  gitea.creative-dragonslayer.de/linuxapps/mirror-package:latest \
+  sync
+```
+
+### 5. Docker Compose Beispiel (`docker-compose.yml`)
+
+```yaml
+services:
+  mirror-package:
+    image: gitea.creative-dragonslayer.de/linuxapps/mirror-package:latest
+    container_name: mirror-package
+    user: "10001:10001"
+    read_only: true
+    cap_drop:
+      - ALL
+    security_opt:
+      - no-new-privileges:true
+    volumes:
+      - ./config:/home/appuser/.config/mirror-package
+      - ./state:/home/appuser/.local/state/mirror-package
+    tmpfs:
+      - /tmp:rw,noexec,nosuid,size=2G
+    environment:
+      - GITEA_URL=https://gitea.creative-dragonslayer.de
+      - GITEA_TOKEN=dein_gitea_api_token
+      - REGISTRY_OWNER=Linuxapps
+      - GITHUB_TOKEN=dein_optionaler_github_pat
+      - LOG_LEVEL=info
+    command: ["sync"]

-## Checkliste zur Verwendung als Template
-
-Wenn du ein neues Projekt aus diesem Template erstellst, gehe folgende Schritte durch:
-
-1. **`Cargo.toml` anpassen**:
-   - `name`: Den Namen deiner Anwendung setzen.
-   - `version`: Initiale Version festlegen (z. B. `0.1.0`).
-   - `authors`, `repository`, `description`, `license`: Projektdaten eintragen.
-   - Paketierungsabschnitte prüfen:
-     - `[package.metadata.deb]`: `maintainer`, `copyright`, `section`, `extended-description` setzen.
-     - `[package.metadata.generate-rpm]`: `requires` anpassen.
-     - `[package.metadata.arch]`: `depends` und `optdepends` anpassen.
-2. **`src/` implementieren**:
-   - Eigene Anwendungslogik in `src/main.rs` (bzw. Modulen / `src/lib.rs`) implementieren.
-   - Tests in `src/` oder `tests/` ergänzen.
-3. **`.cargo/config.toml` prüfen**:
-   - Falls crates.io statt einer privaten Registry genutzt werden soll, den Standard-Registry-Eintrag anpassen oder auskommentieren.
-4. **CI/CD Secrets konfigurieren**:
-   - In den Repository-Einstellungen von Gitea/Forgejo ein Secret `PACKAGE_TOKEN` (bzw. `GITEA_TOKEN`) mit Rechten für Pakete und Releases hinterlegen.
-5. **Dokumentation aktualisieren**:
-   - `README.md` an die konkrete Funktionsweise deiner Anwendung anpassen.

+
+1. **Sofort rotieren/widerrufen**: Das betroffene Secret (Token, Passwort, Schlüssel) beim jeweiligen Dienst ungültig machen und durch ein neues ersetzen. Ein einmal committetes Secret gilt als kompromittiert, auch wenn es später aus der Historie entfernt wird.
+2. **Ursache beheben**: Neues Secret nur noch über Umgebungsvariablen/Secrets-Store einbinden, nicht erneut hart codieren.
+3. **Historie bereinigen (optional, manuell, erst nach Schritt 1)**: Mit `git filter-repo` oder BFG Repo-Cleaner den Commit-Inhalt entfernen, danach `git push --force` in Absprache mit allen Mitwirkenden – bestehende Clones/Forks werden dadurch ungültig.
+4. **Issue schließen**, sobald rotiert wurde. TruffleHog findet das alte Secret ggf. weiterhin in der Historie – nach der Rotation ist das unkritisch.
+
+> Der Wert des Secrets selbst wird hier bewusst nicht ausgegeben, auch nicht gekürzt – nur Detector, Datei und Commit. Fund lässt sich über "Ziel" (Commit-Hash) und "Paket" (Dateipfad) lokalisieren."""
