+# 📦 HOWTO: Release erstellen mit Auto-Changelog-Workflow
+
+Dieses Repository nutzt einen automatisierten CI/CD-Workflow zur **Versionsverwaltung, Changelog-Generierung und Release-Erstellung**.  
+Der gesamte Prozess ist deklarativ und läuft automatisch – ausgelöst durch Änderungen an einer Datei: `VERSION`.
+
+---
+
+## 🧭 Was passiert automatisch?
+
+Sobald Änderungen in `main` landen, prüft der Workflow:
+
+- 🔍 **Hat sich die Datei `VERSION` geändert?**
+  - ❌ **Nein** → es wird nur das `CHANGELOG.md` aktualisiert (unreleased Abschnitt)
+  - ✅ **Ja** → es wird:
+    - ein vollständiger Changelog für diese Version erzeugt
+    - ein Git-Tag `vX.Y.Z` erstellt
+    - ein Release in Gitea veröffentlicht (inkl. Beschreibung aus dem Changelog)
+
+---
+
+## ✅ Wie erzeuge ich ein Release?
+
+### 1. Erhöhe die Version in der Datei `VERSION`
+
+Beispiel:
+
+```txt
+1.2.3
+```
+
+> Diese Datei muss **als eigene Commit-Änderung** erfolgen – idealerweise als letzter Commit in einem PR.
+> Die Commit-Nachricht sollte mit `chore(version)` beginnen, damit dieser nicht im Changelog auftaucht.
+
+---
+
+### 2. Mergen in `main`
+
+Sobald `main` den Commit mit neuer `VERSION` enthält, wird automatisch:
+
+- das `CHANGELOG.md` regeneriert und committed
+- der neue Git-Tag erstellt (`v1.2.3`)
+- ein Gitea Release mit genau diesem Changelog erzeugt
+
+---
+
+## 🛡️ Hinweis zu Tokens & Webhooks
+
+Damit das Release auch korrekt weitere Workflows auslösen kann (z. B. über `on: release`), ist **ein Personal Access Token notwendig**.
+
+### 🔐 Secret: `RELEASE_PUBLISH_TOKEN`
+
+> Lege ein Repository-Secret mit diesem Namen an.  
+> Es sollte ein **Gitea Personal Access Token** mit folgenden Berechtigungen sein:
+
+- `write:repo`
+- `write:release`
+- idealerweise: keine Ablaufzeit
+
+Wird dieser Token **nicht** gesetzt, fällt der Workflow auf `ACTIONS_RUNTIME_TOKEN` zurück, aber:
+- Release wird trotzdem erstellt
+- **⚠️ andere Workflows, die auf `release.published` reagieren, könnten nicht getriggert werden**
+
+---
+
+## 🧪 Debugging-Tipps
+
+- Stelle sicher, dass `VERSION` exakt **eine gültige neue semver-Version** enthält
+- Achte auf den Commit-Log: Changelog-Commits sind mit `chore(changelog):` gekennzeichnet
+- Verwende nur `main` als Trigger-Zweig
+
+---
+
+## 🧩 Erweiterung
+
+In `upload-assets.yml` kannst du beliebige Build-Artefakte automatisch an das Release anhängen, sobald es veröffentlicht ist.
+
+Dafür:
+- liegt das Script `.gitea/scripts/get-release-id.sh`
+- sowie `.gitea/scripts/upload-asset.sh` bereit
+
+Mehr dazu in der Datei: `.gitea/workflows/upload-assets.yml`
+
+---
+
+## 🧘 Best Practice
+
+- Changelog-Generierung nie manuell ausführen
+- Nur `VERSION` ändern, um ein neues Release auszulösen
+- Auf `CHANGELOG.md` nie direkt committen
+- Release-Daten niemals per Hand in Gitea pflegen
+
+📎 Alles wird versioniert, automatisiert und reproduzierbar erzeugt.
+
+---
+
+## 🧠 Commit-Gruppierung & Changelog-Erzeugung
+
+Der Changelog wird auf Basis definierter **Commit-Gruppen** erzeugt.  
+Diese Regeln sind in `cliff.toml` unter `commit_parsers` konfiguriert.
+
+| Prefix / Muster                | Gruppe                    | Beschreibung                                     |
+|-------------------------------|---------------------------|--------------------------------------------------|
+| `feat:`                       | 🚀 Features               | Neue Funktionalität                              |
+| `fix:`                        | 🐛 Bug Fixes              | Fehlerbehebungen                                 |
+| `doc:`                        | 📚 Documentation          | Änderungen an Doku, Readmes etc.                 |
+| `perf:`                       | ⚡ Performance             | Leistungsverbesserungen                          |
+| `refactor:`                   | 🚜 Refactor               | Reorganisation ohne Verhaltensänderung           |
+| `style:`                      | 🎨 Styling                | Formatierung, Whitespaces, Code-Style            |
+| `test:`                       | 🧪 Testing                | Neue oder angepasste Tests                       |
+| `ci:` oder `chore:` (ohne Spezifizierung) | ⚙️ Miscellaneous Tasks | CI-Änderungen, Aufgaben, Wartung etc.            |
+| `chore(changelog)`, `chore(version)`, `chore(release): prepare for`, `chore(deps...)`, `chore(pr)`, `chore(pull)` | *(ignoriert)* | Diese Commits werden im Changelog **ausgelassen** |
+| Commit-Body enthält `security` | 🛡️ Security              | Sicherheitsrelevante Änderungen                  |
+| `revert:`                     | ◀️ Revert                | Rückgängig gemachte Commits                      |
+| alles andere                  | 💼 Other                 | Fallback für nicht erkannte Formate              |
+
+### ✍️ Beispiel:
+
+```bash
+git commit -m "feat: add login endpoint"
+git commit -m "fix: prevent crash on null input"
+git commit -m "chore(version): bump to 1.2.3"
+```
+
+> Nur die ersten beiden erscheinen im Changelog – der dritte wird **automatisch übersprungen**.
+
+---
+
+## 🧾 Umgang mit `CHANGELOG.md` beim Mergen und Releasen
+
+Wenn du automatisiert einen Changelog mit `git-cliff` erzeugst, ist `CHANGELOG.md` ein **generiertes Artefakt** – und kein handgepflegter Quelltext.
+
+Beim Mergen von Feature-Branches in `main` kann es deshalb zu **unnötigen Konflikten** in dieser Datei kommen, obwohl der Inhalt später sowieso neu erzeugt wird.
+
+---
+
+## 🧼 Umgang mit `CHANGELOG.md` in Feature-Branches
+
+Wenn du mit **Feature-Branches** arbeitest, wird `CHANGELOG.md` dort oft automatisch erzeugt.
+Das kann beim späteren Merge in `main` zu **unnötigen Merge-Konflikten** führen.
+
+### ✅ Empfohlene Vorgehensweise
+
+**Bevor du den Branch mit `main` zusammenführst** (Merge oder Cherry-Pick):
+
+```bash
+git rm CHANGELOG.md
+git commit -m "chore(changelog): remove generated CHANGELOG.md before merge"
+git push
+```
+
+Dadurch:
+
+* verhinderst du Merge-Konflikte mit `CHANGELOG.md`
+* wird die Datei bei Feature-Branches nicht mehr automatisch erzeugt
+* bleibt deine Historie sauber und konfliktfrei
+
+> 💡 Der Workflow erzeugt `CHANGELOG.md` automatisch **nur**, wenn:
+>
+> * die Datei schon vorhanden ist **oder**
+> * der Branch `main` heißt
+
+---
+
+## 🧩 Merge-Konflikte verhindern mit `.gitattributes`
+
+Damit Git bei Konflikten in `CHANGELOG.md` **automatisch deine Version bevorzugt**, kannst du folgende Zeile in die Datei `.gitattributes` aufnehmen:
+
+```gitattributes
+CHANGELOG.md merge=ours
+```
+
+Das bedeutet:
+
+* Beim Merge wird die Version aus dem aktuellen Branch (`ours`) behalten
+* Änderungen aus dem Ziel-Branch (`theirs`) werden verworfen
+
+### ✅ So verwendest du es richtig:
+
+1. **Füge die Regel in `main` hinzu**:
+
+```bash
+echo "CHANGELOG.md merge=ours" >> .gitattributes
+git add .gitattributes
+git commit -m "chore(git): prevent merge conflicts in CHANGELOG.md"
+git push origin main
+```
+
+2. **Hole sie in deinen Feature-Branch**:
+
+```bash
+git checkout feature/xyz
+git rebase origin/main
+```
+
+3. **Ab sofort werden Konflikte in `CHANGELOG.md` automatisch aufgelöst** – lokal.
+
+> ⚠️ Hinweis: Plattformen wie **Gitea, GitHub oder GitLab ignorieren `.gitattributes` beim Merge über die Web-Oberfläche**.
+> Führe Merges daher **lokal** durch, wenn du Konflikte verhindern willst.

+# HttpKernel – A Type-Safe Router & Middleware Kernel for Deno
+
+> Fluent routing • Zero-dependency core • 100 % TypeScript
+
+HttpKernel is a small but powerful dispatching engine that turns an ordinary
+`Deno.serve()` loop into a structured, middleware-driven HTTP server.  
+It focuses on **type safety**, **immutability**, and an **expressive builder API**
+while staying framework-agnostic and dependency‑free.
+
+---
+
+## ✨ Key Features
+
+* **Fluent Route Builder** – chain middleware and handlers without side effects  
+* **Static *and* Dynamic Matching** – use URL patterns *or* custom matcher functions  
+* **First-Class Generics** – strongly‑typed `ctx.params`, `ctx.query`, and `ctx.state`  
+* **Pluggable Error Handling** – override 404/500 (and any other status) per kernel  
+* **Response Decorators** – inject CORS headers, security headers, logging, … in one place  
+* **100 % Test Coverage** – built‑in unit tests ensure every edge case is covered
+
+---
+
+## 🚀 Quick Start
+
+```ts
+// Import directly from your repo or deno.land/x
+import { HttpKernel } from "https://deno.land/x/httpkernel/mod.ts";
+
+// 1) Create a kernel (optionally pass overrides)
+const kernel = new HttpKernel();
+
+// 2) Register a route with fluent chaining
+kernel
+  .route({ method: "GET", path: "/hello/:name" })
+  .middleware(async (ctx, next) => {
+    console.log("Incoming request for", ctx.params.name);
+    return await next(); // continue pipeline
+  })
+  .handle(async (ctx) =>
+    new Response(`Hello ${ctx.params.name}!`, { status: 200 })
+  );
+
+// 3) Let Deno serve the kernel
+Deno.serve(kernel.handle);
+```
+
+Run it:
+
+```bash
+deno run --allow-net main.ts
+# → GET http://localhost:8000/hello/Isaac
+```
+
+---
+
+## 🧩 API Overview
+
+| Method / Type         | Purpose                                        | Hints                                                         |
+| --------------------- | ---------------------------------------------- | ------------------------------------------------------------- |
+| `kernel.route(def)`   | Begin defining a new route. Returns `RouteBuilder`. | `def` can be `{ method, path }` **or** `{ method, matcher }`. |
+| `.middleware(fn)`     | Add a middleware to the current builder.       | Each call returns a *new* builder (immutability).             |
+| `.handle(fn)`         | Finalise the route and register the handler.   | Must be called exactly once per route.                        |
+| `kernel.handle(req)`  | Kernel entry point you pass to `Deno.serve()`. | Resolves to a `Response`.                                     |
+
+### Context Shape
+
+```ts
+interface Context<S = Record<string, unknown>> {
+  req: Request;                   // original request
+  params: Record<string>;         // route params e.g. { id: "42" }
+  query: Record<string | string[]>; // parsed query string
+  state: S;                       // per‑request mutable storage
+}
+```
+
+Generics let you supply your own param / query / state types for full IntelliSense.
+
+---
+
+## 🛠️ Configuration
+
+```ts
+new HttpKernel({
+  decorateResponse: (res, ctx) => {
+    // add CORS header globally
+    const headers = new Headers(res.headers);
+    headers.set("Access-Control-Allow-Origin", "*");
+    return new Response(res.body, { ...res, headers });
+  },
+  httpErrorHandlers: {
+    404: () => new Response("Nothing here ☹️", { status: 404 }),
+    500: (_ctx, err) => {
+      console.error(err);
+      return new Response("Custom 500", { status: 500 });
+    },
+  },
+});
+```
+
+Everything is optional – omit what you do not override.
+
+---
+
+## 🧪 Testing
+
+All logic is covered by unit tests using `std@0.204.0/testing`.  
+Run them with:
+
+```bash
+deno test -A
+```
+
+The CI suite checks:
+
+* Route guards (`isStaticRouteDefinition`, `isDynamicRouteDefinition`)
+* Builder immutability & middleware order
+* 404 / 500 fall-backs and error propagation
+* Middleware mis-use (double `next()`, wrong signatures, …)
+
+---
+
+## 📦 Roadmap
+
+* 🔌 Adapter helpers for Oak / Fresh / any framework that can delegate to `kernel.handle`
+* 🔍 Built‑in logger & timing middleware
+* 🔒 CSRF & auth middleware presets
+* 📝 OpenAPI route generator
+
+Contributions & ideas are welcome – feel free to open an issue or PR.

+# 🧩 Plan: `PipelineExecutor<TContext>`
+
+## 🎯 Ziel
+Eine eigenständige, testbare Klasse zur Ausführung einer Middleware- und Handler-Pipeline, die:
+- Linear und sauber das `next()`-Verhalten abbildet
+- Typvalidierung durchführt (`isMiddleware`, `isHandler`)
+- Fehler behandelt und an konfigurierbare Handler weiterleitet
+- Optionale Hooks zur Tracing-Integration bietet (z. B. für Zeitmessung, Logging)
+- Am Ende eine dekorierte `Response` zurückliefert

+        handler: Handler<TContext>,
+        hooks?: IPipelineHooks<TContext>, // optional
+    ): Promise<Response>;
+}
+```
+
+---
+
+## 🪝 Hook-Schnittstelle (`IPipelineHooks`)
+
+```ts
+interface IPipelineHooks<TContext> {
+    onPipelineStart?(ctx: TContext): void;
+    onStepStart?(name: string | undefined, ctx: TContext): void;
+    onStepEnd?(name: string | undefined, ctx: TContext, duration: number): void;
+    onPipelineEnd?(ctx: TContext, totalDuration: number): void;
+}
+```
+
+- `name` ist `undefined`, wenn keine `.name` am Handler/Middleware gesetzt ist
+- Diese Hooks ermöglichen später Logging, Zeitmessung, Statistiken etc.
+- Der `TraceManager` wird dieses Interface implementieren
+
+---
+
+## 🛠️ Interne Aufgaben / Ablauf
+
+1. `run(...)` beginnt mit Aufruf `onPipelineStart(ctx)`
+2. Zeitmessung (`performance.now()`)
+3. Dispatcher-Funktion führt jede Middleware mit `next()`-Kette aus
+4. Vor jedem Aufruf: `onStepStart(name, ctx)`
+5. Nach jedem Aufruf: `onStepEnd(name, ctx, duration)`
+6. Nach letztem Handler: `onPipelineEnd(ctx, totalDuration)`
+7. Ergebnis wird durch `cfg.decorateResponse(res, ctx)` geschickt
+8. Im Fehlerfall: `cfg.httpErrorHandlers[500](ctx, error)`
+
+---
+
+## ✅ Vorteile
+
+- `HttpKernel` ist von Ausführungsdetails entkoppelt
+- Tracing-/Logging-System kann ohne Invasivität angeschlossen werden
+- Sehr gut testbar (z. B. Middleware-Mock + Hook-Aufrufe prüfen)
+- Erweiterbar für Timeout, Async-Context, Abbruchlogik etc.
