-# - .gitea/scripts/get-release-id.sh → ermittelt Release-ID per Tag

-# 🧩 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
-
----
-
-## 🧩 Schnittstelle (API)
-
-```ts
-class PipelineExecutor<TContext extends IContext> {
-    constructor(cfg: IHttpKernelConfig<TContext>);
-
-    run(
-        ctx: TContext,
-        middleware: Middleware<TContext>[],
-        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.
