MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Translated all 95 files from German to English:
- 24 SKILL.md files (frontmatter description/triggers, workflow steps, output templates)
- 50+ references/*.md files (curriculum mappings, pattern references, checklists)
- 25 commands/*.md files (description, argument-hint, body instructions)
- claude/*.md rule files + reference/*.md docs + CLAUDE.md + docs/
- plugins/dev/rules/*.md mirror updated

Also applied dev: prefix to all SKILL.md name: fields (e.g. name: tool-perf -> name: dev:tool-perf).

Preserved: URLs, tool/library names, university names, author names, book titles,
code block contents, technical acronyms (OWASP, WCAG, DORA, SLO, CDC, etc.).
Added language note in design-secure and design-iac for German/Norwegian sources.

 ## Dev Best Practices
 
 ### Security
 
-- Security Headers setzen: CSP (`default-src 'self'`), HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy
-- CSP-Strategie: Nonce-basiert mit `'strict-dynamic'`. `'unsafe-inline'` nur fuer `style-src`
-- Auth an 3 Schichten: Middleware → Route → **Data Access Layer** (wichtigste!)
-- Passwort: bcrypt (cost ≥ 12) / Argon2id, nie Plaintext. Rate Limiting auf Login
+- Set security headers: CSP (`default-src 'self'`), HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy
+- CSP strategy: Nonce-based with `'strict-dynamic'`. `'unsafe-inline'` only for `style-src`
+- Auth at 3 layers: Middleware → Route → **Data Access Layer** (most important!)
+- Password: bcrypt (cost ≥ 12) / Argon2id, never plaintext. Rate limiting on login
 - Sessions: httpOnly, secure, sameSite=Lax
-- Input validieren an System-Grenze: TS → Zod, Python → Pydantic
-- SQL: Immer Prepared Statements. Shell: Nie User-Input in Commands
-- DOM XSS: Kein `innerHTML` mit User-Daten. Trusted Types + DOMPurify bei dynamischem HTML
-- Keine Secrets in Error-Responses. Keine Secrets loggen
-- `.env` nie committen, `.env.example` committen. Env-Validierung beim App-Start (crasht sofort wenn Variable fehlt)
-- Security Assessment: `ruff-S`+`semgrep` (SAST), `pip-audit` (SCA), ASVS 5.0 als Pruefrahmen
-
-### API & Datenbank
-
-- Einheitliches Error-Format: `{ error: { code, message, details } }`
-- Rate Limiting auf Middleware/Gateway-Level. Pagination fuer alle Listen
-- API-Typ: Intern → tRPC. Extern → REST
-- DB: Immer Migrations-Tool (nie manuell SQL auf Prod). Prepared Statements, Least Privilege User, TLS zum DB-Server
-- ORM-Wahl: Query Builder (Drizzle, SQLAlchemy Core) als Sweet Spot
-- Connection Pooling Pflicht. Serverless → externer Pooler
+- Validate input at system boundary: TS → Zod, Python → Pydantic
+- SQL: Always prepared statements. Shell: Never user input in commands
+- DOM XSS: No `innerHTML` with user data. Trusted Types + DOMPurify for dynamic HTML
+- No secrets in error responses. Never log secrets
+- Never commit `.env`, do commit `.env.example`. Validate env vars at app start (crashes immediately if variable is missing)
+- Security assessment: `ruff-S`+`semgrep` (SAST), `pip-audit` (SCA), ASVS 5.0 as verification framework
+
+### API & Database
+
+- Uniform error format: `{ error: { code, message, details } }`
+- Rate limiting at middleware/gateway level. Pagination for all lists
+- API type: Internal → tRPC. External → REST
+- DB: Always use a migration tool (never manual SQL on prod). Prepared statements, least privilege user, TLS to DB server
+- ORM choice: Query builder (Drizzle, SQLAlchemy Core) as sweet spot
+- Connection pooling required. Serverless → external pooler
 
 ### Architecture
 
-- **Feature-basierte** Ordnerstruktur (nicht technisch)
-- Schichtung: Routes → Services → Data Access (2-3 Schichten reichen fuer Solo)
-- **Starte mit Monolith.** Microservices nur bei konkretem Grund
-- Monorepo fuer Full-Stack (Turborepo / pnpm Workspaces / uv Workspaces)
-- 12-Factor: Config in Env, Stateless Processes, Logs auf Stdout, Port Binding
-- Server Components als Default (React/Next.js). `"use client"` nur bei Interaktivitaet
-- Server State (TanStack Query) und Client State (useState/Zustand) nie mischen
+- **Feature-based** folder structure (not technical)
+- Layering: Routes → Services → Data Access (2-3 layers are enough for solo)
+- **Start with a monolith.** Microservices only for a concrete reason
+- Monorepo for full-stack (Turborepo / pnpm Workspaces / uv Workspaces)
+- 12-Factor: Config in env, stateless processes, logs to stdout, port binding
+- Server components as default (React/Next.js). `"use client"` only for interactivity
+- Never mix server state (TanStack Query) with client state (useState/Zustand)
 
 ### GitHub & CI/CD
 
-- Pre-commit Hooks Pflicht: gitleaks → ruff (Lint+Fix inkl. S-Regeln) → Format → Type Check
+- Pre-commit hooks required: gitleaks → ruff (lint+fix incl. S-rules) → format → type check
 - TS: ESLint Flat Config + Prettier + Husky. Python: Ruff + mypy + pre-commit
-- TS Package Manager: pnpm. Python: uv. Lockfiles immer committen
-- CI: Jeder PR durch Pipeline (Install → Lint → Type Check → Build/Test → gitleaks)
-- Branch Protection auf main: Require PR, Status Checks, No Force Push
-- Renovate (nicht Dependabot). devDeps patch Automerge, Major manuell. Dependabot Alerts aktivieren (Security-Meldungen)
-- PR-Groesse: < 400 LOC, darueber aufteilen
+- TS package manager: pnpm. Python: uv. Always commit lockfiles
+- CI: Every PR through pipeline (install → lint → type check → build/test → gitleaks)
+- Branch protection on main: Require PR, status checks, no force push
+- Renovate (not Dependabot). devDeps patch automerge, major manual. Enable Dependabot alerts (security notifications)
+- PR size: < 400 LOC, split above that
 
 ### Testing
 
-- TS: Vitest + Testing Library + MSW (API-Mocking) + Playwright (E2E). Python: pytest + Playwright
-- Prioritaet: 1) API Endpoints 2) Data Transformationen 3) E2E Smoke Test
-- Tests testen Verhalten, nicht Implementierung. Mocke nur an Systemgrenzen
-- Coverage: 70-80% Lines. Kritische Pfade (Auth, Payment) ~100%. 100% gesamt ist kein Ziel
+- TS: Vitest + Testing Library + MSW (API mocking) + Playwright (E2E). Python: pytest + Playwright
+- Priority: 1) API endpoints 2) data transformations 3) E2E smoke test
+- Tests test behavior, not implementation. Mock only at system boundaries
+- Coverage: 70-80% lines. Critical paths (auth, payment) ~100%. 100% overall is not the goal
 
 ### Docker & Deployment
 
-- Multi-Stage Build (Builder + Runner). Base Images mit Digest pinnen
-- Non-root User. HEALTHCHECK. `.dockerignore` pflegen
-- Ports nur auf `127.0.0.1` binden. Named Volumes fuer Prod
-- Reverse Proxy vor der App (Caddy / Nginx). Automatisches HTTPS
-- Health Checks: `/health` (Liveness) + `/ready` (Readiness)
-- Container-Scanning: Trivy (CRITICAL, HIGH, exit-code 1)
-- Feature Flags fuer Zero-Downtime: neues Verhalten hinter Flag → ausrollen → Flag entfernen. Kill Switch fuer sofortiges Rollback
+- Multi-stage build (builder + runner). Pin base images with digest
+- Non-root user. HEALTHCHECK. Maintain `.dockerignore`

+- Container scanning: Trivy (CRITICAL, HIGH, exit-code 1)
+- Feature flags for zero-downtime: new behavior behind flag → roll out → remove flag. Kill switch for immediate rollback
 
 ### Monitoring & Logging
 
-- Structured Logging (JSON): TS → Pino, Python → structlog. Timestamps UTC
-- Error Tracking: Sentry. Uptime: UptimeRobot. Logs: Better Stack / Axiom
-- Alert-Schwellen: Error Rate > 1%, p95 > 2s, CPU/Memory > 80%
-- OpenTelemetry als Standard. Metrics/Traces erst bei Bedarf

+- Error tracking: Sentry. Uptime: UptimeRobot. Logs: Better Stack / Axiom
+- Alert thresholds: error rate > 1%, p95 > 2s, CPU/memory > 80%
+- OpenTelemetry as standard. Metrics/traces only when needed
 
 ### Accessibility
 
-- Gesetzlich Pflicht (EU Accessibility Act, BFSG)
-- Semantisches HTML, Heading-Hierarchie, alt auf Bildern, Fokus-Styles nicht entfernen
-- Testen: axe-core + Lighthouse (automatisch), Tastatur + Screen Reader (manuell)
+- Legally required (EU Accessibility Act, BFSG)
+- Semantic HTML, heading hierarchy, alt on images, don't remove focus styles
+- Testing: axe-core + Lighthouse (automated), keyboard + screen reader (manual)

 ## Authentication & Authorization
 
-- **Defense in Depth:** Auth an 3 Schichten: Middleware → Route/Controller → Data Access Layer (wichtigste!)
-- **Fail Closed:** Bei Fehler Zugang verweigern
-- **Passwort:** bcrypt (cost ≥ 12) / scrypt / Argon2id, nie Plaintext, Timing-safe Vergleiche, Rate Limiting auf Login
-- **Sessions:** Session Cookies mit `httpOnly=true`, `secure=true`, `sameSite=Lax` (Standard-Empfehlung)
-- **JWT:** Nur wenn Statelessness wirklich noetig. Algorithm pinnen (`HS256`/`RS256`, `alg:none` ablehnen), Secret ≥ 256 bit, Refresh Token + Rotation bei Logout
-- **MFA:** TOTP oder WebAuthn (ASVS L2). Account Lockout nach ≥ 5 Fehlversuchen. Password-Reset: Einmal-Token, max. 15 min
-- **Kein eigenes Crypto** -- immer etablierte Libraries
+- **Defense in Depth:** Auth at 3 layers: Middleware → Route/Controller → Data Access Layer (most important!)
+- **Fail Closed:** Deny access on error
+- **Password:** bcrypt (cost ≥ 12) / scrypt / Argon2id, never plaintext, timing-safe comparisons, rate limiting on login
+- **Sessions:** Session cookies with `httpOnly=true`, `secure=true`, `sameSite=Lax` (standard recommendation)
+- **JWT:** Only when statelessness is truly needed. Pin algorithm (`HS256`/`RS256`, reject `alg:none`), secret ≥ 256 bit, refresh token + rotation on logout
+- **MFA:** TOTP or WebAuthn (ASVS L2). Account lockout after ≥ 5 failed attempts. Password reset: one-time token, max. 15 min
+- **No custom crypto** -- always use established libraries

-## Input-Validierung & Output-Encoding
+## Input Validation & Output Encoding
 
-- **Validiere an der System-Grenze** (API-Eingang): Typ, Format, Laenge, Wertebereich
-- **Schema-Validierung:** TypeScript → Zod, Python → Pydantic
-- **Output-Encoding:** Framework-Defaults nutzen. Kein `dangerouslySetInnerHTML` (React), kein `| safe` (Django)
-- **SQL:** Immer Prepared Statements / Parameterized Queries
-- **Shell:** Nie User-Input in Shell-Commands
-- **DOM XSS:** Kein `innerHTML`/`outerHTML` mit User-Daten. Trusted Types + DOMPurify bei dynamischem HTML-Rendering
+- **Validate at system boundary** (API entry): type, format, length, value range
+- **Schema validation:** TypeScript → Zod, Python → Pydantic
+- **Output encoding:** Use framework defaults. No `dangerouslySetInnerHTML` (React), no `| safe` (Django)
+- **SQL:** Always prepared statements / parameterized queries
+- **Shell:** Never user input in shell commands
+- **DOM XSS:** No `innerHTML`/`outerHTML` with user data. Trusted Types + DOMPurify for dynamic HTML rendering
 
 ---
 
 ## API Design
 
-- **Response-Format:** Einheitlich mit `{ error: { code, message, details } }` bei Fehlern
-- **Versionierung:** URL Path (`/api/v1/`)
-- **Rate Limiting:** Middleware/Gateway-Level (Fixed Window oder Token Bucket)
-- **Pagination:** Nie unbegrenzte Listen
-- **Idempotenz:** PUT/DELETE muessen wiederholbar sein
-- **API-Typ:** Internes API → tRPC. Externes/Public API → REST. Komplexe Datenmodelle → GraphQL
+- **Response format:** Uniform with `{ error: { code, message, details } }` on errors
+- **Versioning:** URL path (`/api/v1/`)
+- **Rate limiting:** Middleware/gateway level (fixed window or token bucket)
+- **Pagination:** Never unbounded lists
+- **Idempotency:** PUT/DELETE must be repeatable
+- **API type:** Internal API → tRPC. External/public API → REST. Complex data models → GraphQL
 
 ---
 
-## Datenbank
+## Database
 
-- **Migrationen:** Immer Migration-Tool (nie manuell SQL auf Prod). TS → Drizzle Kit / Prisma Migrate. Python → Alembic
-- **Migrations-Regeln:** Immer vorwaerts, idempotent (`IF NOT EXISTS`), kleine Schritte, in Staging testen
-- **ORM-Wahl:** Query Builder (Drizzle, SQLAlchemy Core) als Sweet Spot. ORM fuer Prototypen. Raw SQL nur fuer komplexe Queries
-- **Connection Pooling:** Pflicht. Serverless → externer Pooler (PgBouncer, Neon Pooler)
-- **Sicherheit:** Prepared Statements, Least Privilege DB User, TLS zum DB-Server, Credentials in Env Vars, Backups testen
-- **PostgreSQL:** `SCRAM-SHA-256` in `pg_hba.conf` (kein `md5`). pgAudit fuer Audit-Trails
+- **Migrations:** Always use a migration tool (never manual SQL on prod). TS → Drizzle Kit / Prisma Migrate. Python → Alembic
+- **Migration rules:** Always forward, idempotent (`IF NOT EXISTS`), small steps, test in staging
+- **ORM choice:** Query builder (Drizzle, SQLAlchemy Core) as sweet spot. ORM for prototypes. Raw SQL only for complex queries
+- **Connection pooling:** Required. Serverless → external pooler (PgBouncer, Neon Pooler)
+- **Security:** Prepared statements, least privilege DB user, TLS to DB server, credentials in env vars, test backups
+- **PostgreSQL:** `SCRAM-SHA-256` in `pg_hba.conf` (not `md5`). pgAudit for audit trails
 
 ---
 
 ## Error Handling & Monitoring
 
-- **Fail Fast:** Fehler sofort melden, nicht verschlucken
-- **Keine Secrets in Errors:** Stack Traces, DB-Queries, Pfade nie an Client
-- **Retry:** Exponentielles Backoff fuer transiente Fehler
-- **Monitoring-Minimum:** Sentry (Error Tracking), Better Stack/UptimeRobot (Uptime), Structured Logging
-- **Alert-Schwellen:** Error Rate > 1%, Response Time p95 > 2s, CPU/Memory > 80%
+- **Fail Fast:** Report errors immediately, don't swallow them
+- **No secrets in errors:** Never leak stack traces, DB queries, paths to client
+- **Retry:** Exponential backoff for transient errors
+- **Monitoring minimum:** Sentry (error tracking), Better Stack/UptimeRobot (uptime), structured logging
+- **Alert thresholds:** Error rate > 1%, response time p95 > 2s, CPU/memory > 80%
 
 ---
 
 ## Logging
 
-- **Strukturiert (JSON)**, Correlation ID pro Request, Timestamps in UTC
-- **Keine Secrets loggen** (API-Keys, Passwort, Tokens, PII)
+- **Structured (JSON)**, correlation ID per request, timestamps in UTC
+- **Never log secrets** (API keys, passwords, tokens, PII)
 - **Tools:** Node.js → Pino, Python → structlog
-- **Log Levels:** error (kaputt), warn (unerwartet), info (normaler Betrieb), debug (Entwicklung)
-- **Aggregation:** Better Stack (1GB/mo free) oder Axiom (500GB/mo free)
+- **Log levels:** error (broken), warn (unexpected), info (normal operation), debug (development)
+- **Aggregation:** Better Stack (1GB/mo free) or Axiom (500GB/mo free)
 
 ---
 
 ## Environment & Secrets
 
-- `.env` nie committen, `.env.example` committen
-- **Env-Validierung beim App-Start:** App crasht sofort wenn Variable fehlt (Zod / Pydantic)
-- **Secrets:** Lokal → `.env`. CI/CD → GitHub Secrets. Production → Vault / Secrets Manager
-- Secrets regelmaessig rotieren (alle 90 Tage oder bei Verdacht auf Kompromittierung sofort)
+- Never commit `.env`, do commit `.env.example`
+- **Validate env vars at app start:** App crashes immediately if variable is missing (Zod / Pydantic)
+- **Secrets:** Local → `.env`. CI/CD → GitHub Secrets. Production → Vault / Secrets Manager
+- Rotate secrets regularly (every 90 days or immediately upon suspected compromise)
 
 ---
 
 ## Caching
 
-- **HTTP:** Statische Assets → `Cache-Control: public, max-age=31536000, immutable`. API → `max-age=60, stale-while-revalidate=300`. Personalisiert → `private, no-cache`. Login/Mutations → `no-store`
-- **App-Level:** Redis fuer Key-Value. In-Memory (`lru-cache` / `cachetools`) fuer Hot Data
-- **Strategie:** Cache-Aside fuer Lese-lastige Apps. TTL-based als einfachster Ansatz
+- **HTTP:** Static assets → `Cache-Control: public, max-age=31536000, immutable`. API → `max-age=60, stale-while-revalidate=300`. Personalized → `private, no-cache`. Login/mutations → `no-store`
+- **App-level:** Redis for key-value. In-memory (`lru-cache` / `cachetools`) for hot data
+- **Strategy:** Cache-aside for read-heavy apps. TTL-based as simplest approach
 
 ---
 
 ## CORS
 
-- `Access-Control-Allow-Origin`: Explizite Domain(s), **nie `*` mit Credentials**
-- Preflight (OPTIONS) immer handeln
-- `Access-Control-Max-Age: 86400` (Preflight cachen)
+- `Access-Control-Allow-Origin`: Explicit domain(s), **never `*` with credentials**
+- Always handle preflight (OPTIONS)
+- `Access-Control-Max-Age: 86400` (cache preflight)
 
 ---
 
 ## File Uploads
 
-- Dateigroesse limitieren (z.B. max 10MB)
-- Dateityp via Magic Bytes validieren (nicht Extension)
-- Nie im Web-Root speichern, zufaelligen Dateinamen generieren
-- Separater Storage (S3/GCS statt lokales Filesystem)
+- Limit file size (e.g. max 10MB)
+- Validate file type via magic bytes (not extension)
+- Never store in web root, generate random filename
+- Separate storage (S3/GCS instead of local filesystem)
 
 ---
 
 ## Accessibility
 
-- **Gesetzlich Pflicht** (EU Accessibility Act seit Juni 2025, BFSG)
-- Semantisches HTML (`<nav>`, `<main>`, `<button>`), richtige Heading-Hierarchie
-- `alt` auf allen `<img>`, `aria-label` fuer Icon-Only Buttons
-- Fokus-Styles nicht entfernen (`:focus-visible`), Skip-to-Content Link
-- Farbe nie als einziger Informationstraeger
-- Testen: axe-core + Lighthouse (automatisch), Tastatur-Test + Screen Reader (manuell)
+- **Legally required** (EU Accessibility Act since June 2025, BFSG)
+- Semantic HTML (`<nav>`, `<main>`, `<button>`), correct heading hierarchy
+- `alt` on all `<img>`, `aria-label` for icon-only buttons
+- Don't remove focus styles (`:focus-visible`), skip-to-content link
+- Never use color as the sole information carrier
+- Testing: axe-core + Lighthouse (automated), keyboard test + screen reader (manual)
 
 ---
 
 ## Performance
 
 - **Core Web Vitals:** LCP < 2.5s, INP < 200ms, CLS < 0.1
-- **Backend:** DB-Indizes, N+1 vermeiden, Pagination, Async I/O, Connection Pooling, Response Compression
-- **Frontend:** Code Splitting (> 200KB), Lazy Loading, WebP/AVIF, Self-hosted Fonts mit `font-display: swap`
+- **Backend:** DB indexes, avoid N+1, pagination, async I/O, connection pooling, response compression
+- **Frontend:** Code splitting (> 200KB), lazy loading, WebP/AVIF, self-hosted fonts with `font-display: swap`
 
 ---
 
 ## Deployment
 
-- **Health Checks:** `/health` (Liveness) + `/ready` (Readiness)
-- **Zero-Downtime:** Rolling Update (minimal), Blue-Green (besser)
-- **Rollback:** Docker Tag Rollback oder Blue-Green Switch (Sekunden)
+- **Health checks:** `/health` (liveness) + `/ready` (readiness)
+- **Zero-downtime:** Rolling update (minimal), blue-green (better)
+- **Rollback:** Docker tag rollback or blue-green switch (seconds)
 
 ---
 
 ## Feature Flags
 
-- **Zweck:** Neues Verhalten hinter Flag verstecken → ausrollen → Flag entfernen. Entkoppelt Deploy von Release
-- **Kill Switch:** Jedes neue Feature braucht einen Deaktivierungs-Pfad fuer sofortiges Rollback ohne Redeploy
-- **Rollout-Reihenfolge:** `disabled → internal → canary (1%) → partial (10%) → full (100%)`
-- **Flag-Lebenszyklus:** Max. 1 Sprint aktiv halten, dann entfernen (verhindert Flag-Schulden)
-- **Tools:** GrowthBook (Open Source, Self-hosted), Unleash (Self-hosted), LaunchDarkly (SaaS)
-- **Nie fuer:** Dauerhafte Konfiguration oder A/B-Tests ohne Cleanup-Plan
+- **Purpose:** Hide new behavior behind a flag → roll out → remove flag. Decouples deploy from release
+- **Kill switch:** Every new feature needs a deactivation path for immediate rollback without redeploy
+- **Rollout order:** `disabled → internal → canary (1%) → partial (10%) → full (100%)`
+- **Flag lifecycle:** Keep active for max. 1 sprint, then remove (prevents flag debt)
+- **Tools:** GrowthBook (open source, self-hosted), Unleash (self-hosted), LaunchDarkly (SaaS)
+- **Never for:** Permanent configuration or A/B tests without a cleanup plan
 
 ---
 
 ## Observability
 
-- **Drei Saeulen:** Logs (was passierte) + Metrics (wie viel) + Traces (wo im System)
-- **OpenTelemetry** als herstellerunabhaengiger Standard
-- **Vier goldene Signale:** Latency, Traffic, Errors, Saturation
-- **Pragmatischer Start:** Sentry + Better Stack/Axiom + UptimeRobot. Metrics/Traces erst bei Bedarf
+- **Three pillars:** Logs (what happened) + metrics (how much) + traces (where in the system)
+- **OpenTelemetry** as vendor-independent standard
+- **Four golden signals:** Latency, traffic, errors, saturation
+- **Pragmatic start:** Sentry + Better Stack/Axiom + UptimeRobot. Metrics/traces only when needed
 
 ---
 
 ## Security Assessment
 
-- **Pruefrahmen:** OWASP ASVS 5.0 (Mai 2025). Level 1 fuer Solo/kleine Teams (~70 Requirements)
-- **SAST:** `ruff-S` (pre-commit) + `semgrep` (CI, cross-file Taint-Analyse)
-- **SCA:** `pip-audit` (Python). `pnpm audit` (Node). Nicht Safety (veraltet)
-- **SBOM:** `syft` (CycloneDX) bei Release-Build -- ISO 27001 / EU CRA
-- **Image-Scan:** `trivy` in CI — CRITICAL+HIGH → exit 1
-- **Threat Modeling:** STRIDE-GPT fuer neue Systeme/Features (einmalig, nicht pro PR)
-- **Rhythmus:** SAST+SCA pro PR → Image-Scan pro Build → STRIDE einmalig pro System
+- **Framework:** OWASP ASVS 5.0 (May 2025). Level 1 for solo/small teams (~70 requirements)
+- **SAST:** `ruff-S` (pre-commit) + `semgrep` (CI, cross-file taint analysis)
+- **SCA:** `pip-audit` (Python). `pnpm audit` (Node). Not Safety (outdated)
+- **SBOM:** `syft` (CycloneDX) on release build -- ISO 27001 / EU CRA
+- **Image scan:** `trivy` in CI — CRITICAL+HIGH → exit 1
+- **Threat modeling:** STRIDE-GPT for new systems/features (once, not per PR)
+- **Cadence:** SAST+SCA per PR → image scan per build → STRIDE once per system

-## Schichtung
+## Layering
 
-- **Kleine Projekte / Prototypen:** 2 Schichten (Routes → Service/Logic)
-- **Mittlere Projekte:** 3 Schichten (Routes → Service → Data Access)
-- **Grosse Projekte / Teams:** Vollstaendige Layered/Clean Architecture
+- **Small projects / prototypes:** 2 layers (routes → service/logic)

+- **Large projects / teams:** Full layered/clean architecture
 
-**Dependency Rule:** Abhaengigkeiten zeigen nur nach innen. Domain-Schicht hat KEINE Abhaengigkeit zu Frameworks, DB, APIs.
+**Dependency rule:** Dependencies point inward only. Domain layer has NO dependency on frameworks, DB, or APIs.
 
-**Clean Architecture:** Erst ab Team-Projekt > 10K LOC oder langlebigem Produkt. Fuer Prototypen/Solo: Over-Engineering.
+**Clean architecture:** Only for team projects > 10K LOC or long-lived products. For prototypes/solo: over-engineering.
 
 ---
 
 ## Monolith vs. Microservices
 
-- **Starte IMMER mit Monolith.** Extrahiere Services nur bei konkretem Grund
-- **Modularer Monolith** als bester Kompromiss: Klare Modul-Grenzen, eigene Domain-Logik und Data Models pro Modul, Kommunikation nur ueber definierte Interfaces
-- Microservices erst wenn: Team waechst, Teile andere Skalierung/Technologie brauchen, Module unabhaengig deployt werden muessen
+- **ALWAYS start with a monolith.** Extract services only for a concrete reason
+- **Modular monolith** as the best compromise: clear module boundaries, own domain logic and data models per module, communication only through defined interfaces
+- Microservices only when: team grows, parts need different scaling/technology, modules need to be deployed independently
 
 ---
 
 ## Monorepo vs. Polyrepo
 
-- **Full-Stack App (Frontend + Backend + Shared):** Monorepo
-- **Solo-Projekt:** Monorepo (Turborepo / pnpm Workspaces)
-- **Unabhaengige Services, verschiedene Teams:** Polyrepo
-- **Monorepo-Tools:** TS → Turborepo. Python → uv Workspaces / Pants
+- **Full-stack app (frontend + backend + shared):** Monorepo
+- **Solo project:** Monorepo (Turborepo / pnpm Workspaces)
+- **Independent services, different teams:** Polyrepo

 ## Backend Patterns
 
-- **Standard:** Service Layer Pattern (Controller → Service → Repository)
-- Controller: HTTP-Handling. Service: Business-Logik. Repository: Daten-Zugriff
-- **CQRS:** Nur wenn Reads >> Writes und verschiedene Optimierungen noetig. Fuer CRUD: Overkill
-- **Event-Driven:** Fuer lose Kopplung und asynchrone Verarbeitung. Tools: RabbitMQ, Redis Streams, AWS SQS
+- **Standard:** Service layer pattern (controller → service → repository)
+- Controller: HTTP handling. Service: business logic. Repository: data access
+- **CQRS:** Only when reads >> writes and different optimizations are needed. For CRUD: overkill
+- **Event-driven:** For loose coupling and asynchronous processing. Tools: RabbitMQ, Redis Streams, AWS SQS
 
 ---
 
 ## Frontend Patterns
 
-- **Component-Hierarchie:** Pages → Feature Components (haben State) → UI Components (Props rein, UI raus) → Hooks → Utils
-- **Server Components** (React/Next.js) als Default. `"use client"` nur bei Interaktivitaet
-- **State Management:**
-  - Lokal: `useState` / `useReducer`
-  - 2-3 Komponenten: Props / Composition
-  - Viele Komponenten: React Context
-  - Komplex: Zustand (leichtgewichtig)
-  - **Server State (Daten vom Backend):** TanStack Query / SWR -- nie mit Client State mischen
+- **Component hierarchy:** Pages → feature components (have state) → UI components (props in, UI out) → hooks → utils
+- **Server components** (React/Next.js) as default. `"use client"` only for interactivity
+- **State management:**
+  - Local: `useState` / `useReducer`
+  - 2-3 components: props / composition
+  - Many components: React Context
+  - Complex: Zustand (lightweight)
+  - **Server state (data from backend):** TanStack Query / SWR -- never mix with client state
 
 ---
 
 ## Data Fetching
 
-- **SSR:** SEO wichtig, initialer Load schnell (Next.js Server Components)
-- **SSG:** Inhalt aendert sich selten (`generateStaticParams()`)
-- **ISR:** Statisch + periodisch aktualisiert (`revalidate`)
-- **CSR:** Hinter Login, Dashboard-Apps (TanStack Query)
-- **Deduplizierung:** TanStack Query dedupliziert automatisch
-- **Optimistic Updates:** UI sofort updaten, API im Hintergrund, Rollback bei Fehler
+- **SSR:** SEO important, fast initial load (Next.js server components)
+- **SSG:** Content changes rarely (`generateStaticParams()`)
+- **ISR:** Static + periodically updated (`revalidate`)
+- **CSR:** Behind login, dashboard apps (TanStack Query)
+- **Deduplication:** TanStack Query deduplicates automatically
+- **Optimistic updates:** Update UI immediately, API in background, rollback on error

-## Docker Architektur
+## Docker Architecture
 
-- **Single-Container:** Reverse Proxy → App Container (mit Volume fuer Daten)
-- **Multi-Container:** docker-compose mit App + DB + Cache, Named Volumes, Health Checks
-- Container kommunizieren ueber **Service-Namen** (nicht IPs): `postgres://db:5432/myapp`
-- Ports nur auf `127.0.0.1` binden (nicht ans Internet): `"127.0.0.1:3000:3000"`
-- Named Volumes fuer Produktion, Bind Mounts fuer Entwicklung
-- **Resource Limits** setzen (Memory, CPU)
-- **Log-Rotation** konfigurieren (`max-size: "10m"`, `max-file: "3"`)
+- **Single container:** Reverse proxy → app container (with volume for data)
+- **Multi-container:** docker-compose with app + DB + cache, named volumes, health checks
+- Containers communicate via **service names** (not IPs): `postgres://db:5432/myapp`

+- Named volumes for production, bind mounts for development
+- Set **resource limits** (memory, CPU)
+- Configure **log rotation** (`max-size: "10m"`, `max-file: "3"`)
 
 ---
 
 ## Reverse Proxy & SSL
 
-- **Immer einen Reverse Proxy** vor der App (SSL, Rate Limiting, Static Files, Compression, Security Headers)
-- **Caddy:** Einfachstes Setup, automatisches HTTPS (Let's Encrypt)
-- **Nginx:** Performant, Industriestandard
-- **Cloudflare Tunnel:** Kein offener Port noetig, DDoS-Schutz
+- **Always a reverse proxy** in front of the app (SSL, rate limiting, static files, compression, security headers)
+- **Caddy:** Simplest setup, automatic HTTPS (Let's Encrypt)
+- **Nginx:** Performant, industry standard
+- **Cloudflare Tunnel:** No open port needed, DDoS protection
 
 ---
 
 ## Environments
 
-- **Solo / Kleine Teams:** 2-Tier reicht (Dev + Production)
-  - Absicherung ohne Staging: CI mit Tests, Docker-Image lokal testen, Feature Flags, Health Checks + Rollback
-- **Staging** erst bei: mehreren Entwicklern, komplexen DB-Migrationen, UAT, Compliance
-- Docker Compose Overrides: `docker-compose.yml` (Base/Prod) + `docker-compose.override.yml` (Dev, auto-geladen)
+- **Solo / small teams:** 2-tier is enough (dev + production)
+  - Protection without staging: CI with tests, test Docker image locally, feature flags, health checks + rollback
+- **Staging** only when: multiple developers, complex DB migrations, UAT, compliance
+- Docker Compose overrides: `docker-compose.yml` (base/prod) + `docker-compose.override.yml` (dev, auto-loaded)

-## Testing-Strategie
+## Testing Strategy
 
-- **Test-Pyramide als Leitfaden, nicht Gesetz:** Library → viele Unit. API/Backend → viele Integration. UI → mehr E2E
-- **Tests testen Verhalten, nicht Implementierung** (Refactoring darf Tests nicht brechen)
-- **Arrange → Act → Assert**, ein Konzept pro Test, keine Test-Interdependenz
-- **Mocke an Systemgrenzen** (HTTP, DB, Filesystem). Nie eigene Logik mocken. Fakes > Mocks
-- **Coverage:** 70-80% Lines, 60-70% Branches. Kritische Pfade (Auth, Payment) ~100%. 100% gesamt ist KEIN Ziel
-- **Pragmatisch:** Test-During als Default. TDD fuer Bugs und komplexe Logik. Prototypen: nachholen vor Production
+- **Test pyramid as a guide, not a law:** Library → many unit. API/backend → many integration. UI → more E2E
+- **Tests test behavior, not implementation** (refactoring must not break tests)
+- **Arrange → Act → Assert**, one concept per test, no test interdependence
+- **Mock at system boundaries** (HTTP, DB, filesystem). Never mock own logic. Fakes > mocks
+- **Coverage:** 70-80% lines, 60-70% branches. Critical paths (auth, payment) ~100%. 100% overall is NOT the goal
+- **Pragmatic:** Test-during as default. TDD for bugs and complex logic. Prototypes: catch up before production

 ## Security
 
-- Security Headers setzen: CSP (`default-src 'self'`), HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy
-- CSP-Strategie: Nonce-basiert mit `'strict-dynamic'`. `'unsafe-inline'` nur fuer `style-src`
-- Auth an 3 Schichten: Middleware → Route → **Data Access Layer** (wichtigste!)
-- Passwort: bcrypt (cost ≥ 12) / Argon2id, nie Plaintext. Rate Limiting auf Login
+- Set security headers: CSP (`default-src 'self'`), HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy
+- CSP strategy: Nonce-based with `'strict-dynamic'`. `'unsafe-inline'` only for `style-src`
+- Auth at 3 layers: Middleware → Route → **Data Access Layer** (most important!)
+- Password: bcrypt (cost ≥ 12) / Argon2id, never plaintext. Rate limiting on login
 - Sessions: httpOnly, secure, sameSite=Lax
-- Input validieren an System-Grenze: TS → Zod, Python → Pydantic
-- SQL: Immer Prepared Statements. Shell: Nie User-Input in Commands
-- DOM XSS: Kein `innerHTML` mit User-Daten. Trusted Types + DOMPurify bei dynamischem HTML
-- Keine Secrets in Error-Responses. Keine Secrets loggen
-- `.env` nie committen, `.env.example` committen. Env-Validierung beim App-Start (crasht sofort wenn Variable fehlt)
-- Security Assessment: `ruff-S`+`semgrep` (SAST), `pip-audit` (SCA), ASVS 5.0 als Pruefrahmen
-
-## API & Datenbank
-
-- Einheitliches Error-Format: `{ error: { code, message, details } }`
-- Rate Limiting auf Middleware/Gateway-Level. Pagination fuer alle Listen
-- API-Typ: Intern → tRPC. Extern → REST
-- DB: Immer Migrations-Tool (nie manuell SQL auf Prod). Prepared Statements, Least Privilege User, TLS zum DB-Server
-- ORM-Wahl: Query Builder (Drizzle, SQLAlchemy Core) als Sweet Spot
-- Connection Pooling Pflicht. Serverless → externer Pooler
+- Validate input at system boundary: TS → Zod, Python → Pydantic
+- SQL: Always prepared statements. Shell: Never user input in commands
+- DOM XSS: No `innerHTML` with user data. Trusted Types + DOMPurify for dynamic HTML
+- No secrets in error responses. Never log secrets
+- Never commit `.env`, do commit `.env.example`. Validate env vars at app start (crashes immediately if variable is missing)
+- Security assessment: `ruff-S`+`semgrep` (SAST), `pip-audit` (SCA), ASVS 5.0 as verification framework
+
+## API & Database
+
+- Uniform error format: `{ error: { code, message, details } }`
+- Rate limiting at middleware/gateway level. Pagination for all lists
+- API type: Internal → tRPC. External → REST
+- DB: Always use a migration tool (never manual SQL on prod). Prepared statements, least privilege user, TLS to DB server
+- ORM choice: Query builder (Drizzle, SQLAlchemy Core) as sweet spot
+- Connection pooling required. Serverless → external pooler
 
 ## Architecture
 
-- **Feature-basierte** Ordnerstruktur (nicht technisch)
-- Schichtung: Routes → Services → Data Access (2-3 Schichten reichen fuer Solo)
-- **Starte mit Monolith.** Microservices nur bei konkretem Grund
-- Monorepo fuer Full-Stack (Turborepo / pnpm Workspaces / uv Workspaces)
-- 12-Factor: Config in Env, Stateless Processes, Logs auf Stdout, Port Binding
-- Server Components als Default (React/Next.js). `"use client"` nur bei Interaktivitaet
-- Server State (TanStack Query) und Client State (useState/Zustand) nie mischen
+- **Feature-based** folder structure (not technical)
+- Layering: Routes → Services → Data Access (2-3 layers are enough for solo)
+- **Start with a monolith.** Microservices only for a concrete reason
+- Monorepo for full-stack (Turborepo / pnpm Workspaces / uv Workspaces)
+- 12-Factor: Config in env, stateless processes, logs to stdout, port binding
+- Server components as default (React/Next.js). `"use client"` only for interactivity
+- Never mix server state (TanStack Query) with client state (useState/Zustand)
 
 ## GitHub & CI/CD
 
-- Pre-commit Hooks Pflicht: gitleaks → ruff (Lint+Fix inkl. S-Regeln) → Format → Type Check
+- Pre-commit hooks required: gitleaks → ruff (lint+fix incl. S-rules) → format → type check
 - TS: ESLint Flat Config + Prettier + Husky. Python: Ruff + mypy + pre-commit
-- TS Package Manager: pnpm. Python: uv. Lockfiles immer committen
-- CI: Jeder PR durch Pipeline (Install → Lint → Type Check → Build/Test → gitleaks)
-- Branch Protection auf main: Require PR, Status Checks, No Force Push
-- Renovate (nicht Dependabot). devDeps patch Automerge, Major manuell. Dependabot Alerts aktivieren (Security-Meldungen)
-- PR-Groesse: < 400 LOC, darueber aufteilen
+- TS package manager: pnpm. Python: uv. Always commit lockfiles
+- CI: Every PR through pipeline (install → lint → type check → build/test → gitleaks)
+- Branch protection on main: Require PR, status checks, no force push
+- Renovate (not Dependabot). devDeps patch automerge, major manual. Enable Dependabot alerts (security notifications)
+- PR size: < 400 LOC, split above that
 
 ## Testing
 
-- TS: Vitest + Testing Library + MSW (API-Mocking) + Playwright (E2E). Python: pytest + Playwright
-- Prioritaet: 1) API Endpoints 2) Data Transformationen 3) E2E Smoke Test
-- Tests testen Verhalten, nicht Implementierung. Mocke nur an Systemgrenzen
-- Coverage: 70-80% Lines. Kritische Pfade (Auth, Payment) ~100%. 100% gesamt ist kein Ziel
+- TS: Vitest + Testing Library + MSW (API mocking) + Playwright (E2E). Python: pytest + Playwright

+- Tests test behavior, not implementation. Mock only at system boundaries
+- Coverage: 70-80% lines. Critical paths (auth, payment) ~100%. 100% overall is not the goal
 
 ## Docker & Deployment
 
-- Multi-Stage Build (Builder + Runner). Base Images mit Digest pinnen
-- Non-root User. HEALTHCHECK. `.dockerignore` pflegen
-- Ports nur auf `127.0.0.1` binden. Named Volumes fuer Prod
-- Reverse Proxy vor der App (Caddy / Nginx). Automatisches HTTPS
-- Health Checks: `/health` (Liveness) + `/ready` (Readiness)
-- Container-Scanning: Trivy (CRITICAL, HIGH, exit-code 1)
-- Feature Flags fuer Zero-Downtime: neues Verhalten hinter Flag → ausrollen → Flag entfernen. Kill Switch fuer sofortiges Rollback
+- Multi-stage build (builder + runner). Pin base images with digest

+- Container scanning: Trivy (CRITICAL, HIGH, exit-code 1)
+- Feature flags for zero-downtime: new behavior behind flag → roll out → remove flag. Kill switch for immediate rollback
 
 ## Monitoring & Logging
 
-- Structured Logging (JSON): TS → Pino, Python → structlog. Timestamps UTC
-- Error Tracking: Sentry. Uptime: UptimeRobot. Logs: Better Stack / Axiom
-- Alert-Schwellen: Error Rate > 1%, p95 > 2s, CPU/Memory > 80%
-- OpenTelemetry als Standard. Metrics/Traces erst bei Bedarf

+- OpenTelemetry as standard. Metrics/traces only when needed
 
 ## Accessibility
 
-- Gesetzlich Pflicht (EU Accessibility Act, BFSG)
-- Semantisches HTML, Heading-Hierarchie, alt auf Bildern, Fokus-Styles nicht entfernen
-- Testen: axe-core + Lighthouse (automatisch), Tastatur + Screen Reader (manuell)

 ## Authentication & Authorization
 
-- **Defense in Depth:** Auth an 3 Schichten: Middleware → Route/Controller → Data Access Layer (wichtigste!)
-- **Fail Closed:** Bei Fehler Zugang verweigern
-- **Passwort:** bcrypt (cost ≥ 12) / scrypt / Argon2id, nie Plaintext, Timing-safe Vergleiche, Rate Limiting auf Login
-- **Sessions:** Session Cookies mit `httpOnly=true`, `secure=true`, `sameSite=Lax` (Standard-Empfehlung)
-- **JWT:** Nur wenn Statelessness wirklich noetig. Algorithm pinnen (`HS256`/`RS256`, `alg:none` ablehnen), Secret ≥ 256 bit, Refresh Token + Rotation bei Logout
-- **MFA:** TOTP oder WebAuthn (ASVS L2). Account Lockout nach ≥ 5 Fehlversuchen. Password-Reset: Einmal-Token, max. 15 min
-- **Kein eigenes Crypto** -- immer etablierte Libraries

-## Input-Validierung & Output-Encoding
+## Input Validation & Output Encoding
 
-- **Validiere an der System-Grenze** (API-Eingang): Typ, Format, Laenge, Wertebereich
-- **Schema-Validierung:** TypeScript → Zod, Python → Pydantic
-- **Output-Encoding:** Framework-Defaults nutzen. Kein `dangerouslySetInnerHTML` (React), kein `| safe` (Django)
-- **SQL:** Immer Prepared Statements / Parameterized Queries
-- **Shell:** Nie User-Input in Shell-Commands
-- **DOM XSS:** Kein `innerHTML`/`outerHTML` mit User-Daten. Trusted Types + DOMPurify bei dynamischem HTML-Rendering

 ## API Design
 
-- **Response-Format:** Einheitlich mit `{ error: { code, message, details } }` bei Fehlern
-- **Versionierung:** URL Path (`/api/v1/`)
-- **Rate Limiting:** Middleware/Gateway-Level (Fixed Window oder Token Bucket)
-- **Pagination:** Nie unbegrenzte Listen
-- **Idempotenz:** PUT/DELETE muessen wiederholbar sein

 ## Error Handling & Monitoring
 
-- **Fail Fast:** Fehler sofort melden, nicht verschlucken
-- **Keine Secrets in Errors:** Stack Traces, DB-Queries, Pfade nie an Client
-- **Retry:** Exponentielles Backoff fuer transiente Fehler
-- **Monitoring-Minimum:** Sentry (Error Tracking), Better Stack/UptimeRobot (Uptime), Structured Logging

 ## Caching
 
-- **HTTP:** Statische Assets → `Cache-Control: public, max-age=31536000, immutable`. API → `max-age=60, stale-while-revalidate=300`. Personalisiert → `private, no-cache`. Login/Mutations → `no-store`
-- **App-Level:** Redis fuer Key-Value. In-Memory (`lru-cache` / `cachetools`) fuer Hot Data
-- **Strategie:** Cache-Aside fuer Lese-lastige Apps. TTL-based als einfachster Ansatz
+- **HTTP:** Static assets → `Cache-Control: public, max-age=31536000, immutable`. API → `max-age=60, stale-while-revalidate=300`. Personalized → `private, no-cache`. Login/mutations → `no-store`
+- **App-level:** Redis for key-value. In-memory (`lru-cache` / `cachetools`) for hot data
+- **Strategy:** Cache-aside for read-heavy apps. TTL-based as simplest approach
 
 ---
 
 ## CORS
 
-- `Access-Control-Allow-Origin`: Explizite Domain(s), **nie `*` mit Credentials**
-- Preflight (OPTIONS) immer handeln
-- `Access-Control-Max-Age: 86400` (Preflight cachen)
+- `Access-Control-Allow-Origin`: Explicit domain(s), **never `*` with credentials**
+- Always handle preflight (OPTIONS)
+- `Access-Control-Max-Age: 86400` (cache preflight)
 
 ---
 
 ## File Uploads
 
-- Dateigroesse limitieren (z.B. max 10MB)
-- Dateityp via Magic Bytes validieren (nicht Extension)
-- Nie im Web-Root speichern, zufaelligen Dateinamen generieren
-- Separater Storage (S3/GCS statt lokales Filesystem)
+- Limit file size (e.g. max 10MB)
+- Validate file type via magic bytes (not extension)
+- Never store in web root, generate random filename
+- Separate storage (S3/GCS instead of local filesystem)
 
 ---
 
 ## Accessibility
 
-- **Gesetzlich Pflicht** (EU Accessibility Act seit Juni 2025, BFSG)
-- Semantisches HTML (`<nav>`, `<main>`, `<button>`), richtige Heading-Hierarchie
-- `alt` auf allen `<img>`, `aria-label` fuer Icon-Only Buttons
-- Fokus-Styles nicht entfernen (`:focus-visible`), Skip-to-Content Link
-- Farbe nie als einziger Informationstraeger
-- Testen: axe-core + Lighthouse (automatisch), Tastatur-Test + Screen Reader (manuell)
+- **Legally required** (EU Accessibility Act since June 2025, BFSG)
+- Semantic HTML (`<nav>`, `<main>`, `<button>`), correct heading hierarchy
+- `alt` on all `<img>`, `aria-label` for icon-only buttons
+- Don't remove focus styles (`:focus-visible`), skip-to-content link
+- Never use color as the sole information carrier
+- Testing: axe-core + Lighthouse (automated), keyboard test + screen reader (manual)

 ## Performance
 
 - **Core Web Vitals:** LCP < 2.5s, INP < 200ms, CLS < 0.1
-- **Backend:** DB-Indizes, N+1 vermeiden, Pagination, Async I/O, Connection Pooling, Response Compression
-- **Frontend:** Code Splitting (> 200KB), Lazy Loading, WebP/AVIF, Self-hosted Fonts mit `font-display: swap`
+- **Backend:** DB indexes, avoid N+1, pagination, async I/O, connection pooling, response compression
+- **Frontend:** Code splitting (> 200KB), lazy loading, WebP/AVIF, self-hosted fonts with `font-display: swap`
 
 ---
 
 ## Deployment
 
-- **Health Checks:** `/health` (Liveness) + `/ready` (Readiness)
-- **Zero-Downtime:** Rolling Update (minimal), Blue-Green (besser)
-- **Rollback:** Docker Tag Rollback oder Blue-Green Switch (Sekunden)
+- **Health checks:** `/health` (liveness) + `/ready` (readiness)
+- **Zero-downtime:** Rolling update (minimal), blue-green (better)
+- **Rollback:** Docker tag rollback or blue-green switch (seconds)
 
 ---
 
 ## Feature Flags
 
-- **Zweck:** Neues Verhalten hinter Flag verstecken → ausrollen → Flag entfernen. Entkoppelt Deploy von Release
-- **Kill Switch:** Jedes neue Feature braucht einen Deaktivierungs-Pfad fuer sofortiges Rollback ohne Redeploy
-- **Rollout-Reihenfolge:** `disabled → internal → canary (1%) → partial (10%) → full (100%)`
-- **Flag-Lebenszyklus:** Max. 1 Sprint aktiv halten, dann entfernen (verhindert Flag-Schulden)
-- **Tools:** GrowthBook (Open Source, Self-hosted), Unleash (Self-hosted), LaunchDarkly (SaaS)
-- **Nie fuer:** Dauerhafte Konfiguration oder A/B-Tests ohne Cleanup-Plan
+- **Purpose:** Hide new behavior behind a flag → roll out → remove flag. Decouples deploy from release
+- **Kill switch:** Every new feature needs a deactivation path for immediate rollback without redeploy
+- **Rollout order:** `disabled → internal → canary (1%) → partial (10%) → full (100%)`
+- **Flag lifecycle:** Keep active for max. 1 sprint, then remove (prevents flag debt)
+- **Tools:** GrowthBook (open source, self-hosted), Unleash (self-hosted), LaunchDarkly (SaaS)
+- **Never for:** Permanent configuration or A/B tests without a cleanup plan
 
 ---
 
 ## Observability
 
-- **Drei Saeulen:** Logs (was passierte) + Metrics (wie viel) + Traces (wo im System)
-- **OpenTelemetry** als herstellerunabhaengiger Standard
-- **Vier goldene Signale:** Latency, Traffic, Errors, Saturation
-- **Pragmatischer Start:** Sentry + Better Stack/Axiom + UptimeRobot. Metrics/Traces erst bei Bedarf
+- **Three pillars:** Logs (what happened) + metrics (how much) + traces (where in the system)
+- **OpenTelemetry** as vendor-independent standard
+- **Four golden signals:** Latency, traffic, errors, saturation
+- **Pragmatic start:** Sentry + Better Stack/Axiom + UptimeRobot. Metrics/traces only when needed

-## Schichtung
+## Layering
 
-- **Kleine Projekte / Prototypen:** 2 Schichten (Routes → Service/Logic)
-- **Mittlere Projekte:** 3 Schichten (Routes → Service → Data Access)
-- **Grosse Projekte / Teams:** Vollstaendige Layered/Clean Architecture
+- **Small projects / prototypes:** 2 layers (routes → service/logic)
+- **Medium projects:** 3 layers (routes → service → data access)
+- **Large projects / teams:** Full layered/clean architecture
 
-**Dependency Rule:** Abhaengigkeiten zeigen nur nach innen. Domain-Schicht hat KEINE Abhaengigkeit zu Frameworks, DB, APIs.
+**Dependency rule:** Dependencies point inward only. Domain layer has NO dependency on frameworks, DB, or APIs.
 
-**Clean Architecture:** Erst ab Team-Projekt > 10K LOC oder langlebigem Produkt. Fuer Prototypen/Solo: Over-Engineering.
+**Clean architecture:** Only for team projects > 10K LOC or long-lived products. For prototypes/solo: over-engineering.
 
 ---
 
 ## Monolith vs. Microservices
 
-- **Starte IMMER mit Monolith.** Extrahiere Services nur bei konkretem Grund
-- **Modularer Monolith** als bester Kompromiss: Klare Modul-Grenzen, eigene Domain-Logik und Data Models pro Modul, Kommunikation nur ueber definierte Interfaces
-- Microservices erst wenn: Team waechst, Teile andere Skalierung/Technologie brauchen, Module unabhaengig deployt werden muessen
+- **ALWAYS start with a monolith.** Extract services only for a concrete reason
+- **Modular monolith** as the best compromise: clear module boundaries, own domain logic and data models per module, communication only through defined interfaces
+- Microservices only when: team grows, parts need different scaling/technology, modules need to be deployed independently
 
 ---
 
 ## Monorepo vs. Polyrepo
 
-- **Full-Stack App (Frontend + Backend + Shared):** Monorepo
-- **Solo-Projekt:** Monorepo (Turborepo / pnpm Workspaces)
-- **Unabhaengige Services, verschiedene Teams:** Polyrepo
-- **Monorepo-Tools:** TS → Turborepo. Python → uv Workspaces / Pants
+- **Full-stack app (frontend + backend + shared):** Monorepo
+- **Solo project:** Monorepo (Turborepo / pnpm Workspaces)
+- **Independent services, different teams:** Polyrepo
+- **Monorepo tools:** TS → Turborepo. Python → uv Workspaces / Pants
 
 ---
 
 ## Backend Patterns
 
-- **Standard:** Service Layer Pattern (Controller → Service → Repository)
-- Controller: HTTP-Handling. Service: Business-Logik. Repository: Daten-Zugriff
-- **CQRS:** Nur wenn Reads >> Writes und verschiedene Optimierungen noetig. Fuer CRUD: Overkill
-- **Event-Driven:** Fuer lose Kopplung und asynchrone Verarbeitung. Tools: RabbitMQ, Redis Streams, AWS SQS
+- **Standard:** Service layer pattern (controller → service → repository)
+- Controller: HTTP handling. Service: business logic. Repository: data access
+- **CQRS:** Only when reads >> writes and different optimizations are needed. For CRUD: overkill
+- **Event-driven:** For loose coupling and asynchronous processing. Tools: RabbitMQ, Redis Streams, AWS SQS
 
 ---
 
 ## Frontend Patterns
 
-- **Component-Hierarchie:** Pages → Feature Components (haben State) → UI Components (Props rein, UI raus) → Hooks → Utils
-- **Server Components** (React/Next.js) als Default. `"use client"` nur bei Interaktivitaet
-- **State Management:**
-  - Lokal: `useState` / `useReducer`
-  - 2-3 Komponenten: Props / Composition
-  - Viele Komponenten: React Context
-  - Komplex: Zustand (leichtgewichtig)
-  - **Server State (Daten vom Backend):** TanStack Query / SWR -- nie mit Client State mischen
+- **Component hierarchy:** Pages → feature components (have state) → UI components (props in, UI out) → hooks → utils
+- **Server components** (React/Next.js) as default. `"use client"` only for interactivity
+- **State management:**
+  - Local: `useState` / `useReducer`
+  - 2-3 components: props / composition
+  - Many components: React Context
+  - Complex: Zustand (lightweight)
+  - **Server state (data from backend):** TanStack Query / SWR -- never mix with client state
 
 ---
 
 ## Data Fetching
 
-- **SSR:** SEO wichtig, initialer Load schnell (Next.js Server Components)
-- **SSG:** Inhalt aendert sich selten (`generateStaticParams()`)
-- **ISR:** Statisch + periodisch aktualisiert (`revalidate`)
-- **CSR:** Hinter Login, Dashboard-Apps (TanStack Query)
-- **Deduplizierung:** TanStack Query dedupliziert automatisch
-- **Optimistic Updates:** UI sofort updaten, API im Hintergrund, Rollback bei Fehler
+- **SSR:** SEO important, fast initial load (Next.js server components)
+- **SSG:** Content changes rarely (`generateStaticParams()`)
+- **ISR:** Static + periodically updated (`revalidate`)
+- **CSR:** Behind login, dashboard apps (TanStack Query)
+- **Deduplication:** TanStack Query deduplicates automatically
+- **Optimistic updates:** Update UI immediately, API in background, rollback on error
 
 ---
 
-## Docker Architektur
+## Docker Architecture
 
-- **Single-Container:** Reverse Proxy → App Container (mit Volume fuer Daten)
-- **Multi-Container:** docker-compose mit App + DB + Cache, Named Volumes, Health Checks
-- Container kommunizieren ueber **Service-Namen** (nicht IPs): `postgres://db:5432/myapp`
-- Ports nur auf `127.0.0.1` binden (nicht ans Internet): `"127.0.0.1:3000:3000"`
-- Named Volumes fuer Produktion, Bind Mounts fuer Entwicklung
-- **Resource Limits** setzen (Memory, CPU)
-- **Log-Rotation** konfigurieren (`max-size: "10m"`, `max-file: "3"`)
+- **Single container:** Reverse proxy → app container (with volume for data)
+- **Multi-container:** docker-compose with app + DB + cache, named volumes, health checks
+- Containers communicate via **service names** (not IPs): `postgres://db:5432/myapp`
+- Bind ports only to `127.0.0.1` (not to the internet): `"127.0.0.1:3000:3000"`
+- Named volumes for production, bind mounts for development
+- Set **resource limits** (memory, CPU)
+- Configure **log rotation** (`max-size: "10m"`, `max-file: "3"`)
 
 ---
 
 ## Reverse Proxy & SSL
 
-- **Immer einen Reverse Proxy** vor der App (SSL, Rate Limiting, Static Files, Compression, Security Headers)
-- **Caddy:** Einfachstes Setup, automatisches HTTPS (Let's Encrypt)
-- **Nginx:** Performant, Industriestandard
-- **Cloudflare Tunnel:** Kein offener Port noetig, DDoS-Schutz
+- **Always a reverse proxy** in front of the app (SSL, rate limiting, static files, compression, security headers)
+- **Caddy:** Simplest setup, automatic HTTPS (Let's Encrypt)
+- **Nginx:** Performant, industry standard
+- **Cloudflare Tunnel:** No open port needed, DDoS protection
 
 ---
 
 ## Environments
 
-- **Solo / Kleine Teams:** 2-Tier reicht (Dev + Production)
-  - Absicherung ohne Staging: CI mit Tests, Docker-Image lokal testen, Feature Flags, Health Checks + Rollback
-- **Staging** erst bei: mehreren Entwicklern, komplexen DB-Migrationen, UAT, Compliance
-- Docker Compose Overrides: `docker-compose.yml` (Base/Prod) + `docker-compose.override.yml` (Dev, auto-geladen)
+- **Solo / small teams:** 2-tier is enough (dev + production)
+  - Protection without staging: CI with tests, test Docker image locally, feature flags, health checks + rollback
+- **Staging** only when: multiple developers, complex DB migrations, UAT, compliance
+- Docker Compose overrides: `docker-compose.yml` (base/prod) + `docker-compose.override.yml` (dev, auto-loaded)

-## Testing-Strategie
+## Testing Strategy
 
-- **Test-Pyramide als Leitfaden, nicht Gesetz:** Library → viele Unit. API/Backend → viele Integration. UI → mehr E2E
-- **Tests testen Verhalten, nicht Implementierung** (Refactoring darf Tests nicht brechen)
-- **Arrange → Act → Assert**, ein Konzept pro Test, keine Test-Interdependenz
-- **Mocke an Systemgrenzen** (HTTP, DB, Filesystem). Nie eigene Logik mocken. Fakes > Mocks
-- **Coverage:** 70-80% Lines, 60-70% Branches. Kritische Pfade (Auth, Payment) ~100%. 100% gesamt ist KEIN Ziel
-- **Pragmatisch:** Test-During als Default. TDD fuer Bugs und komplexe Logik. Prototypen: nachholen vor Production
+- **Test pyramid as a guide, not a law:** Library → many unit. API/backend → many integration. UI → more E2E
+- **Tests test behavior, not implementation** (refactoring must not break tests)
+- **Arrange → Act → Assert**, one concept per test, no test interdependence
+- **Mock at system boundaries** (HTTP, DB, filesystem). Never mock own logic. Fakes > mocks
+- **Coverage:** 70-80% lines, 60-70% branches. Critical paths (auth, payment) ~100%. 100% overall is NOT the goal
+- **Pragmatic:** Test-during as default. TDD for bugs and complex logic. Prototypes: catch up before production

-## API-Dokumentation
+## API Documentation
 
-- **Code-First** fuer Solo/Kleine Teams (Doku aus Code generiert)
-- **API-First** wenn Frontend/Backend getrennte Teams
-- **FastAPI:** Gold-Standard (automatisch aus Type Hints + Pydantic)
-- **TS/Node:** Scalar als modernes OpenAPI UI
-- Versionierung: URL Path (`/api/v1/`) fuer oeffentliche APIs
+- **Code-first** for solo/small teams (docs generated from code)
+- **API-first** when frontend/backend are separate teams
+- **FastAPI:** Gold standard (automatic from type hints + Pydantic)
+- **TS/Node:** Scalar as modern OpenAPI UI
+- Versioning: URL path (`/api/v1/`) for public APIs
 
 ---
 
 ## Background Jobs
 
-- Nicht jeder Job braucht eine Queue. Einfache Scheduled Tasks: Cron + Script
-- **Wenn Queue noetig:** TS → BullMQ (Redis). Python → Celery / ARQ (Redis)
-- **Retry:** Exponential Backoff, Max Retries (3-5), Dead Letter Queue
-- **Idempotenz:** Jobs muessen mehrfach ausfuehrbar sein ohne Seiteneffekte
+- Not every job needs a queue. Simple scheduled tasks: cron + script
+- **When queue is needed:** TS → BullMQ (Redis). Python → Celery / ARQ (Redis)
+- **Retry:** Exponential backoff, max retries (3-5), dead letter queue
+- **Idempotency:** Jobs must be executable multiple times without side effects

 ## Security
 
-- Security Headers setzen: CSP (`default-src 'self'`), HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy
-- CSP-Strategie: Nonce-basiert mit `'strict-dynamic'`. `'unsafe-inline'` nur fuer `style-src`
-- Auth an 3 Schichten: Middleware → Route → **Data Access Layer** (wichtigste!)
-- Passwort: bcrypt (cost ≥ 12) / Argon2id, nie Plaintext. Rate Limiting auf Login

+- Auth at 3 layers: Middleware → Route → **Data Access Layer** (most important!)
+- Password: bcrypt (cost ≥ 12) / Argon2id, never plaintext. Rate limiting on login
 - Sessions: httpOnly, secure, sameSite=Lax
-- Input validieren an System-Grenze: TS → Zod, Python → Pydantic
-- SQL: Immer Prepared Statements. Shell: Nie User-Input in Commands
-- DOM XSS: Kein `innerHTML` mit User-Daten. Trusted Types + DOMPurify bei dynamischem HTML
-- Keine Secrets in Error-Responses. Keine Secrets loggen
-- `.env` nie committen, `.env.example` committen. Env-Validierung beim App-Start (crasht sofort wenn Variable fehlt)

-- Unit Tests: < 5 min (sonst aufteilen)
-- Integration Tests: < 15 min (parallel laufen lassen)
-- Kein manueller Schritt vor Prod (außer expliziter Approval bei high-risk)
+Principles:
+- Each stage gives fast feedback (fail fast)
+- Unit Tests: < 5 min (split up if longer)
+- Integration Tests: < 15 min (run in parallel)
+- No manual step before Prod (except explicit approval for high-risk)

+**1b — Parallelization**
 
 - Unit Tests + Lint + Security Scan → parallel

-- Build-Cache: Dependencies cachen (npm ci, pip, Maven) → 60–80% schneller
+- Integration Tests after successful build → parallel where possible
+- Build cache: cache dependencies (npm ci, pip, Maven) → 60–80% faster
 
 **1c — Artifact Management**
 
-- Einmal bauen, überall deployen (kein Re-Build pro Environment)
-- Artifact versionieren mit Git SHA oder Semantic Version
-- Container Images: in Registry pushen, per Tag promoten (nicht re-bauen)
+- Build once, deploy everywhere (no re-build per environment)

-- Breaking Change oder unsicheres Feature → Feature Flag
-- Granulares Rollout-Feedback nötig → Canary
-- Schneller Traffic-Switch Rollback → Blue-Green
-- Standard-Fall mit Health Checks → Rolling Update

-## Feature Flags — Entscheidung
+## Feature Flags — Decision
 
-**Verwende Feature Flags wenn:**
-- Neues Feature unsicher ob production-stable
-- Breaking Change an bestehender API (beide Versionen parallel betreiben)
-- A/B-Test oder graduelle Einführung nach User-Segmenten
-- Kill-Switch für sofortiges Rollback ohne Deployment nötig
+**Use Feature Flags when:**
+- New feature is uncertain whether production-stable
+- Breaking change to existing API (run both versions in parallel)
+- A/B test or gradual rollout by user segment
+- Kill switch needed for immediate rollback without deployment
 
-**Nicht verwenden wenn:**
-- Rein technische Refactorings ohne Behavior-Change
-- Feature ist bereits vollständig getestet und stabil
-- Zu viele Flags akkumulieren sich (Tech-Debt: Flags löschen nach Rollout)
+**Do not use when:**
+- Purely technical refactorings without behavior change
+- Feature is already fully tested and stable
+- Too many flags accumulate (tech debt: delete flags after rollout)

 ## Trunk-Based Development
 
-Kernprinzipien (aus "Accelerate", Kap. 4):
-- Alle Entwickler committen mindestens 1× täglich auf main/trunk
-- Feature Branches leben maximal 1–2 Tage
-- Feature Flags für unfertige Features, nicht Long-Lived Branches
-- CI läuft bei jedem Commit auf main
+Core principles (from "Accelerate", Ch. 4):
+- All developers commit at least 1× daily to main/trunk
+- Feature branches live at most 1–2 days
+- Feature flags for incomplete features, not long-lived branches
+- CI runs on every commit to main
 
-**Warum:** Long-Lived Branches = verzögertes Integration-Feedback = große Merge-Konflikte = seltene Deployments = niedrige DORA-Performance. Empirisch belegt.
+**Why:** Long-lived branches = delayed integration feedback = large merge conflicts = infrequent deployments = low DORA performance. Empirically proven.

 ## Core Patterns
 
-| Pattern | Beschreibung | Anti-Pattern |
+| Pattern | Description | Anti-Pattern |
 |---|---|---|
-| **Immutable Infrastructure** | Infra-Ressourcen nie aendern — immer neu provisionieren | Mutable: Server mit SSH patchen (Config Drift) |
-| **Dynamic Infrastructure** | Ressourcen per API erzeugen/loeschen | Static: manuelles Setup, Snowflake Server |
-| **Single Source of Truth** | Ein Repo definiert Soll-Zustand — kein manuelles Eingreifen | IaC + parallele manuelle Aenderungen |
-| **Idempotent Apply** | Mehrfaches Apply → immer gleicher Zustand | Scripts mit Seiteneffekten bei Re-Run |
-| **Small Focused Stacks** | Ein Stack pro Concern (Network / Compute / App) | Monolithic Stack (alles in einem) |
-| **Composable Modules** | Module = wiederverwendbare Bausteine mit klaren Inputs/Outputs | Copy-Paste IaC |
-| **GitOps** | Git = Single Source of Truth, Aenderungen nur per PR | Direkte CLI-Aenderungen in Prod |
+| **Immutable Infrastructure** | Never change infra resources — always re-provision | Mutable: patching servers via SSH (Config Drift) |
+| **Dynamic Infrastructure** | Create/delete resources via API | Static: manual setup, Snowflake Server |
+| **Single Source of Truth** | One repo defines desired state — no manual intervention | IaC + parallel manual changes |
+| **Idempotent Apply** | Multiple applies → always the same state | Scripts with side effects on re-run |
+| **Small Focused Stacks** | One stack per concern (network / compute / app) | Monolithic stack (everything in one) |
+| **Composable Modules** | Modules = reusable building blocks with clear inputs/outputs | Copy-Paste IaC |
+| **GitOps** | Git = Single Source of Truth, changes only via PR | Direct CLI changes in prod |
 
-**Snowflake Anti-Pattern:** Jeder Server wurde durch manuelle Aenderungen einzigartig — nicht reproduzierbar, nicht skalierbar, nicht loeschbar ohne Angst.
+**Snowflake Anti-Pattern:** Every server became unique through manual changes — not reproducible, not scalable, not deletable without fear.

-## Modul-Design Prinzipien
+## Module Design Principles
 
-| Prinzip | Beschreibung |
+| Principle | Description |
 |---|---|
-| Single Responsibility | Ein Modul = ein klar abgegrenzter Concern |
-| Stabile Interfaces | Input-Variablen und Outputs aendern sich selten |
-| Keine versteckten Abhaengigkeiten | Alles was ein Modul braucht, kommt als Input |
-| Versionierung | Module per Git-Tag versionieren (kein `?ref=main` in Prod) |
-| Minimale Outputs | Nur was Downstream-Module wirklich brauchen |
+| Single Responsibility | One module = one clearly scoped concern |
+| Stable Interfaces | Input variables and outputs change rarely |
+| No Hidden Dependencies | Everything a module needs comes as input |
+| Versioning | Version modules via Git tag (no `?ref=main` in prod) |
+| Minimal Outputs | Only what downstream modules actually need |

-## Workspace-Strategie
+## Workspace Strategy
 
-| Ansatz | Wann | Einschraenkung |
+| Approach | When | Limitation |
 |---|---|---|
-| **Workspace per Environment** | Gleicher Code, verschiedene Variablenwerte (dev/staging/prod) | Schlechte Isolation: ein Plan betrifft alle Envs |
-| **Separate State-Pfade** | Verschiedene `backend` Konfigurationen pro Env | Mehr Komplexitaet, aber saubere Isolation |
-| **Separate Repos** | Enterprise, strikte Isolation, verschiedene Teams pro Env | Hoechste Isolation, aber viel Overhead |
+| **Workspace per environment** | Same code, different variable values (dev/staging/prod) | Poor isolation: one plan affects all envs |
+| **Separate state paths** | Different `backend` configurations per env | More complexity, but clean isolation |
+| **Separate repos** | Enterprise, strict isolation, different teams per env | Highest isolation, but much overhead |
 
-Empfehlung fuer die meisten Teams: **Separate State-Pfade** (z.B. `s3://bucket/envs/prod/terraform.tfstate`).
+Recommendation for most teams: **Separate state paths** (e.g. `s3://bucket/envs/prod/terraform.tfstate`).

-4. Drift-Detection automatisieren: plan im Schedule-Job, Alert bei Diff != 0
+1. terraform plan          → shows drift between state and actual infra

+| Existing resource should be under IaC | `terraform import` — bring resource into state without change |
+| Resource after manual deletion | Re-provision via `apply` |

+- **Topic guard:** Detect and reject out-of-scope queries (classifier or LLM prompt)
 
 ### Cost & Latency
-- **Prompt-Caching:** Wiederverwendbare System-Prompts cachen (Anthropic / OpenAI support)
-- **Semantic Caching:** Ähnliche Queries → gleiche Antwort (Redis + Embedding-Similarity)

 ## LLM-as-Judge Patterns
 
-| Pattern | Skala | Prompt-Struktur |
+| Pattern | Scale | Prompt structure |
 |---|---|---|
-| **Pairwise Comparison** | A vs. B | "Welche Antwort ist besser: A oder B?" |
-| **Likert Scale** | 1–5 | "Bewerte auf einer Skala 1–5: Faithfulness / Relevanz / Vollständigkeit" |
-| **Reference-based** | Pass/Fail | "Enthält die Antwort alle Fakten aus der Referenz?" |
-| **G-Eval** | 0–1 | Schrittweise Evaluation mit Chain-of-Thought |
+| **Pairwise comparison** | A vs. B | "Which answer is better: A or B?" |
+| **Likert scale** | 1–5 | "Rate on a scale of 1–5: faithfulness / relevance / completeness" |
+| **Reference-based** | Pass/Fail | "Does the answer contain all facts from the reference?" |
+| **G-Eval** | 0–1 | Step-by-step evaluation with chain-of-thought |
 
-**Bias-Risiken:** Positions-Bias (A wird bevorzugt), Längen-Bias (längere Antwort gewinnt), Self-Enhancement (Modell bevorzugt eigene Outputs). Gegenmittel: Positionen tauschen, mehrere Judges, diverse Modelle.
+**Bias risks:** Position bias (A is preferred), length bias (longer answer wins), self-enhancement (model prefers its own outputs). Countermeasures: swap positions, multiple judges, diverse models.

-3. **Vertrauensbildend**: Kalibriertes Vertrauen ist eine explizite Design-Entscheidung
-4. **Erklärt**: Jede Wahl hat ein "Warum" das das Team versteht und verteidigen kann
-5. **Iterativ**: UX-Entscheidungen revisitieren wenn sich Nutzerverhalten zeigt
+1. **User-centered**: user needs and mental models before interface decisions
+2. **Contextual**: interaction model follows the task, not the technology
+3. **Trust-building**: calibrated trust is an explicit design decision
+4. **Explained**: every choice has a "why" the team understands and can defend
+5. **Iterative**: revisit UX decisions as user behavior becomes visible
 
-Besonders für KI-Features gilt: **Das Interface ist der Kontrakt zwischen dem System
-und dem Nutzer.** Ein schlecht kommuniziertes KI-Feature erzeugt Misstrauen oder
-gefährliche Überabhängigkeit — beides ist ein UX-Fehler.
+Especially for AI features: **The interface is the contract between the system
+and the user.** A poorly communicated AI feature creates distrust or
+dangerous over-reliance — both are UX failures.

 ## Design Workflow
 
-### Phase 0 — Kontext verstehen
+### Phase 0 — Understand Context
 
-Erfasse aus der Beschreibung oder durch Lesen vorhandener Dateien:
+Gather from the description or by reading existing files:
 
-1. **Was macht das Produkt / Feature?** (1–2 Sätze)
-2. **Wer sind die Nutzer?** (Expertise, Kontext, Zugangsmittel)
-3. **Welche Aufgaben sollen erfüllt werden?** (primäre User Goals)
-4. **Ist KI / ML beteiligt?** (Empfehlungen, Generierung, Klassifikation, Agenten)
-5. **Was ist der Kanal?** (Web, Mobile, Voice, Embedded, Dashboard, Chat)
-6. **Gibt es Accessibility-Anforderungen?** (gesetzlich: EU Accessibility Act / BFSG)
-7. **Welches Platform Design System?** (Material Design 3, Apple HIG, agnostisch, eigenes) — bestimmt Color Roles, Elevation, Shape, Typography-Defaults
+1. **What does the product / feature do?** (1–2 sentences)
+2. **Who are the users?** (expertise, context, access method)
+3. **What tasks need to be accomplished?** (primary user goals)
+4. **Is AI / ML involved?** (recommendations, generation, classification, agents)
+5. **What is the channel?** (web, mobile, voice, embedded, dashboard, chat)
+6. **Are there accessibility requirements?** (legal: EU Accessibility Act / BFSG)
+7. **Which platform design system?** (Material Design 3, Apple HIG, agnostic, custom) — determines color roles, elevation, shape, typography defaults
 
-Fehlt Wesentliches: **einmal** nachfragen, nicht raten. Annahmen explizit als
-`[Annahme]` markieren.
+If something essential is missing: ask **once**, do not guess. Mark assumptions
+explicitly as `[Assumption]`.

-### Phase 0.5 — Platform Design System festlegen (wenn visuelles Design Teil der Aufgabe)
+### Phase 0.5 — Establish Platform Design System (when visual design is part of the task)
 
-Einmal entscheiden, dann konsistent durchhalten:
+Decide once, then apply consistently:
 
-| Plattform / Kontext | System | Kernprinzip |
-|--------------------|--------|------------|
-| Android / Web (Google-Stil) | Material Design 3 | Color Roles, Tonal Elevation, Shape |
+| Platform / Context | System | Core Principle |
+|--------------------|--------|----------------|
+| Android / Web (Google-style) | Material Design 3 | Color Roles, Tonal Elevation, Shape |
 | iOS / macOS | Apple HIG | Clarity, Deference, Depth |
 | Enterprise / B2B | IBM Carbon | Accessibility-first, Data-Dense Patterns |
-| Kein Kontext / eigenes System | Agnostisch + Design Tokens | Volle Kontrolle |
+| No context / custom system | Agnostic + Design Tokens | Full control |

-Diese Entscheidung unter "Entscheidungen" in `design-ux.md` dokumentieren.
-Wenn kein System gewählt: explizit als `[Annahme: agnostisch]` markieren.
+Document this decision under "Decisions" in `design-ux.md`.
+If no system is chosen: mark explicitly as `[Assumption: agnostic]`.

-### Phase 1 — Interaktionsmodell wählen
+### Phase 1 — Choose Interaction Model
 
-Das Interaktionsmodell bestimmt alles Folgende. Wähle bewusst, nicht per Default.
+The interaction model determines everything that follows. Choose deliberately, not by default.
 
-| Modell | Wann geeignet | Risiko |
-|--------|--------------|--------|
-| Klassische GUI | Strukturierte Aufgaben, vorhersehbare Inputs | Kein direktes Risiko |
-| Chat / Konversation | Explorative, unstrukturierte Anfragen | Articulation Barrier, leeres Input-Feld schreckt ab |
-| Hybrid (GUI + Prompt) | KI-Features in strukturierten Produkten | Komplexität; zwei mentale Modelle |
-| Ambient / Proaktiv | KI greift ein ohne explizite Aufforderung | HAX G3: falscher Zeitpunkt zerstört Vertrauen |
-| Voice | Freihand-Szenarien, Accessibility | Kein visuelles Feedback; Fehlerkorrektur schwer |
+| Model | When appropriate | Risk |
+|-------|-----------------|------|
+| Classic GUI | Structured tasks, predictable inputs | No direct risk |
+| Chat / Conversation | Exploratory, unstructured requests | Articulation barrier, empty input field is off-putting |
+| Hybrid (GUI + Prompt) | AI features in structured products | Complexity; two mental models |
+| Ambient / Proactive | AI intervenes without explicit request | HAX G3: wrong timing destroys trust |
+| Voice | Hands-free scenarios, accessibility | No visual feedback; error correction is difficult |
 
-**NNG-Regel:** Nicht Chat-First per Default. Chat validieren gegen echte Nutzerbedürfnisse.
-Wenn Nutzer präzise, strukturierte Aufgaben haben → GUI. Wenn explorative, sprachliche
-Aufgaben → Chat oder Hybrid.
+**NNG rule:** Do not default to chat. Validate chat against real user needs.
+If users have precise, structured tasks → GUI. If exploratory, language-based
+tasks → Chat or Hybrid.

+**Onboarding sequence (4 questions in this order):**
 
-1. **Was kann es?** — Fähigkeiten klar zeigen, mit Beispielen (PAIR P3: "Benefit, not technology")
-2. **Was kann es nicht?** — Grenzen explizit nennen bevor der erste Fehler passiert (HAX G1/G2)
-3. **Wie ändert es sich?** — System lernt / verbessert sich / ändert sich; kommunizieren (HAX G14/G18)
-4. **Wie verbessert man es?** — Feedback-Mechanismen sichtbar machen (HAX G15/G16)
+1. **What can it do?** — Show capabilities clearly, with examples (PAIR P3: "Benefit, not technology")
+2. **What can it not do?** — State limitations explicitly before the first failure occurs (HAX G1/G2)
+3. **How does it change?** — System learns / improves / changes; communicate this (HAX G14/G18)
+4. **How can it be improved?** — Make feedback mechanisms visible (HAX G15/G16)
 
-**ELIZA-Effekt verhindern (NNG):**
-- Anthropomorphe Formulierungen prüfen: "Ich verstehe dich" → besser "Ich interpretiere deine Anfrage als…"
-- Limitierungen offen benennen, nicht verstecken
-- Kompetenz zeigen statt Menschenähnlichkeit (NNG: "Prioritize smarts over sentience")
+**Prevent the ELIZA effect (NNG):**
+- Check anthropomorphic phrasing: "I understand you" → better "I interpret your request as…"
+- Openly state limitations, do not hide them
+- Show competence rather than human-likeness (NNG: "Prioritize smarts over sentience")
 
-**Generative Variabilität kommunizieren (CHI 2024 P4):**
-- Wenn gleiche Inputs variable Outputs erzeugen: explizit zeigen (Google Gemini: Multiple Drafts)
-- Nicht als Fehler darstellen — als Feature erklären
+**Communicate generative variability (CHI 2024 P4):**

-## Schritt 0 — Thema & Typ klären
+## Step 0 — Clarify Topic & Type
 
-**Fragen stellen:**
+**Ask questions:**
 
-1. **Thema:** Was soll der Skill können? Ein Satz.
-2. **Typ bestimmen:**
+1. **Topic:** What should the skill do? One sentence.
+2. **Determine type:**
 
-   | Typ | Wann | Beispiele |
+   | Type | When | Examples |
    |---|---|---|
-   | `design-*` | Etwas von Null entwerfen, Entscheidungen treffen | design-api, design-secure, design-ux |
-   | `review-*` | Bestehendes analysieren, Findings reporten | review-arch, review-secure, review-ux |
-   | `tool-*` | Operativer Workflow, kein Design/Review | tool-debug, tool-test, tool-style |
-   | `meta-*` | Repo- oder Plugin-Wartung | meta-install, meta-sync, meta-drift |
+   | `design-*` | Design something from scratch, make decisions | design-api, design-secure, design-ux |
+   | `review-*` | Analyze existing work, report findings | review-arch, review-secure, review-ux |
+   | `tool-*` | Operational workflow, not design/review | tool-debug, tool-test, tool-style |
+   | `meta-*` | Repo or plugin maintenance | meta-install, meta-sync, meta-drift |
 
-3. **Trigger-Keywords:** Mit welchen Sätzen würde ein Nutzer diesen Skill aufrufen? (5–10 Beispiele)
-4. **Output:** Was produziert der Skill? (Datei, Report, Analyse, Menü?)
+3. **Trigger keywords:** What phrases would a user use to invoke this skill? (5–10 examples)
+4. **Output:** What does the skill produce? (File, report, analysis, menu?)
 
-→ Erst wenn Thema, Typ und Output klar sind: weiter zu Schritt 1.

-Was gehört NICHT in SKILL.md (→ references/):
-- Lookup-Tabellen (Concept → Course Link)
-- Checklisten (Dark Patterns, Security Checks)
-- Framework-Referenzen (HAX Guidelines, WCAG Success Criteria)
-- Design-Token-Tabellen, Pattern-Kataloge

-Zeigt den Delta — ohne automatisch zu überschreiben.
+Compares what is in the target project with what our rule files currently define.
+Shows the delta — without automatically overwriting.
 
-## Schritt 0 — Quellen laden
+## Step 0 — Load Sources
 
-1. **Aktueller Stand (SOLL):** Rule-Files aus `${CLAUDE_PLUGIN_ROOT}/rules/`
-   - `essential-rules.md` — immer
-   - `app-rules.md`, `github-rules.md`, `architecture-rules.md` — nur wenn im Projekt-Block vorhanden
+1. **Current state (TARGET):** Rule files from `${CLAUDE_PLUGIN_ROOT}/rules/`
+   - `essential-rules.md` — always
+   - `app-rules.md`, `github-rules.md`, `architecture-rules.md` — only if present in the project block
 
-2. **Projekt-Stand (IST):** `CLAUDE.md` im Ziel-Projekt lesen
-   - Block zwischen `DEV-BEST-PRACTICES:START` und `DEV-BEST-PRACTICES:END` extrahieren
-   - Falls kein Marker: gesamte `CLAUDE.md` auf Best-Practices-Inhalte prüfen
-   - Falls keine `CLAUDE.md`: zu `install-rules` weiterleiten
+2. **Project state (ACTUAL):** Read `CLAUDE.md` in the target project
+   - Extract block between `DEV-BEST-PRACTICES:START` and `DEV-BEST-PRACTICES:END`
+   - If no marker: check entire `CLAUDE.md` for best-practices content
+   - If no `CLAUDE.md`: redirect to `install-rules`
 
-3. **Version aus Marker lesen** (falls vorhanden):
+3. **Read version from marker** (if present):
    ```text
    <!-- Version: essential-rules.md @ 2024-01-15 -->
    ```
-   → Wie alt ist die installierte Version?
+   → How old is the installed version?
 
-## Schritt 1 — Delta-Analyse
+## Step 1 — Delta Analysis
 
-Vergleiche strukturiert auf drei Ebenen:
+Compare structurally on three levels:
 
-**Fehlende Sections** (im SOLL, nicht im IST):
-- Neue Sections die nach dem letzten Install hinzugekommen sind
-- Sections die für diesen Stack relevant wären aber fehlen
+**Missing sections** (in TARGET, not in ACTUAL):
+- New sections added after the last install
+- Sections that would be relevant for this stack but are missing
 
-**Veraltete Inhalte** (im IST, in SOLL geändert oder entfernt):
-- Regeln die sich inhaltlich geändert haben (z.B. Tool-Wechsel: `eslint` → `biome`)
-- Regeln die gelöscht wurden weil überholt
-- Versions-spezifische Regeln die nicht mehr gelten (z.B. deprecated APIs)
+**Outdated content** (in ACTUAL, changed or removed in TARGET):
+- Rules that have changed in content (e.g., tool change: `eslint` → `biome`)
+- Rules that were deleted because outdated
+- Version-specific rules that no longer apply (e.g., deprecated APIs)
 
-**Projekt-Ausnahmen bewahren** (im IST, nicht im SOLL — absichtlich):
-- `[Ausnahme: …]` Blöcke
-- Projektspezifische Ergänzungen
-- Diese werden nie als "Drift" gewertet
+**Preserve project exceptions** (in ACTUAL, not in TARGET — intentional):
+- `[Exception: …]` blocks
+- Project-specific additions
+- These are never counted as "drift"

-### Fehlende Sections (neu seit letztem Install)
-- [Section-Name] in essential-rules.md → [kurze Beschreibung was neu ist]
+### Missing Sections (new since last install)
+- [Section name] in essential-rules.md → [brief description of what is new]
 
-### Veraltete Regeln
-- [Regel] → war: "[alter Wert]" / jetzt: "[neuer Wert]"
-  Grund: [warum geändert]
+### Outdated Rules
+- [Rule] → was: "[old value]" / now: "[new value]"
+  Reason: [why changed]
 
-### Empfehlung
-[ ] Update durchführen — X Sections betroffen, Aufwand: S/M
-[ ] Nur kritische Changes übernehmen (Security, Breaking Changes)
-[ ] Manuell prüfen wegen Projekt-Ausnahmen
+### Recommendation
+[ ] Perform update — X sections affected, effort: S/M
+[ ] Only adopt critical changes (security, breaking changes)
+[ ] Review manually due to project exceptions
 
-### Nächster Schritt
-`/dev-best-practices:install-rules` mit `--update` um den Block zu aktualisieren.
-Projekt-Ausnahmen bleiben erhalten.
+### Next Step
+`/dev-best-practices:install-rules` with `--update` to update the block.
+Project exceptions are preserved.
 ```
 
-## Regeln
-- Niemals automatisch etwas ändern — nur Report.
-- Projekt-spezifische Ausnahmen und Ergänzungen niemals als Drift werten.
-- Wenn kein `DEV-BEST-PRACTICES:START` Marker vorhanden: explizit darauf hinweisen
-  dass ein Update-Tracking erst nach `install-rules` möglich ist.
-- Bei sehr alten Ständen (>6 Monate): Security-relevante Änderungen als `[KRITISCH]` markieren.
+## Rules
+- Never change anything automatically — report only.
+- Never count project-specific exceptions and additions as drift.
+- If no `DEV-BEST-PRACTICES:START` marker is present: explicitly point out
+  that update tracking is only possible after `install-rules`.
+- For very old states (>6 months): mark security-relevant changes as `[CRITICAL]`.

 # Install Rules
 
-Fügt `essential-rules.md` (oder ausgewählte Sections) als dedizierten Block in die
-`CLAUDE.md` eines Zielprojekts ein — oder aktualisiert einen bestehenden Block in-place.
-Bestehender Projektkontext und Projekt-Ausnahmen werden nie überschrieben.
+Inserts `essential-rules.md` (or selected sections) as a dedicated block into the
+`CLAUDE.md` of a target project — or updates an existing block in-place.
+Existing project context and project exceptions are never overwritten.
 
-## Schritt 0 — Modus erkennen (Install vs. Update)
+## Step 0 — Detect Mode (Install vs. Update)
 
-1. **Ziel-`CLAUDE.md` lokalisieren** (aktuelles Verzeichnis `./CLAUDE.md`)
+1. **Locate target `CLAUDE.md`** (current directory `./CLAUDE.md`)
 
-2. **Modus bestimmen:**
+2. **Determine mode:**
 
-   | Situation | Modus |
+   | Situation | Mode |
    |---|---|
-   | Keine `CLAUDE.md` vorhanden | **Neu anlegen** |
-   | `CLAUDE.md` ohne `DEV-BEST-PRACTICES:START` Marker | **Erstinstallation** |
-   | `CLAUDE.md` mit `DEV-BEST-PRACTICES:START` Marker | **Update** |
-   | `--force` Flag | **Update** auch ohne Marker (Block neu erzeugen) |
+   | No `CLAUDE.md` present | **Create new** |
+   | `CLAUDE.md` without `DEV-BEST-PRACTICES:START` marker | **Initial install** |
+   | `CLAUDE.md` with `DEV-BEST-PRACTICES:START` marker | **Update** |
+   | `--force` flag | **Update** even without marker (regenerate block) |
 
-3. **Umfang bestimmen** (Default: `--essential`):
-   - `--essential` → nur `essential-rules.md` (~80 Zeilen, empfohlen)
-   - `--full` → alle vier Rule-Files (essential + app + github + architecture)
-   - `--section <name>` → einzelne Section, z.B. `--section security`
-   - `--update` → gleichen Umfang wie beim letzten Install verwenden (aus Marker lesen)
+3. **Determine scope** (default: `--essential`):
+   - `--essential` → only `essential-rules.md` (~80 lines, recommended)
+   - `--full` → all four rule files (essential + app + github + architecture)
+   - `--section <name>` → individual section, e.g. `--section security`
+   - `--update` → use same scope as last install (read from marker)
 
-   Falls keine Angabe und Update-Modus: den im Marker dokumentierten Umfang beibehalten.
+   If no specification and update mode: retain the scope documented in the marker.
 
-## Schritt 1 — Regeln vorbereiten
+## Step 1 — Prepare Rules
 
-1. Lese die gewählten Rule-Files aus `${CLAUDE_PLUGIN_ROOT}/rules/`
-2. Bei `--section`: die relevante Section extrahieren
-3. Prüfe ob Regeln zum erkannten Stack passen:
-   - Python-Projekt ohne TypeScript → TypeScript-spezifische Regeln als `[optional]` markieren
-   - Kein Frontend → Frontend/CSS-Sections überspringen
-   - Solo-Projekt → ASVS L1 als Default vermerken
+1. Read the chosen rule files from `${CLAUDE_PLUGIN_ROOT}/rules/`
+2. For `--section`: extract the relevant section
+3. Check if rules fit the detected stack:
+   - Python project without TypeScript → mark TypeScript-specific rules as `[optional]`
+   - No frontend → skip frontend/CSS sections
+   - Solo project → note ASVS L1 as default
 
-## Schritt 2a — Erstinstallation
+## Step 2a — Initial Install
 
-**Block-Format:**
+**Block format:**
 ```markdown
-<!-- DEV-BEST-PRACTICES:START — via /dev-best-practices:install-rules aktualisieren -->
-<!-- Version: essential-rules.md @ <Datum> | Umfang: essential -->
+<!-- DEV-BEST-PRACTICES:START — update via /dev-best-practices:install-rules -->
+<!-- Version: essential-rules.md @ <date> | Scope: essential -->
 
 ## Dev Best Practices
 
-[Inhalt der Regel-Files]
+[Content of rule files]
 
 <!-- DEV-BEST-PRACTICES:END -->
 ```
 
-**Einfüge-Position:**
-- Nach dem projektspezifischen Kontext (Architektur, Commands)
-- Vor projekt-spezifischen Ausnahmen falls vorhanden
-- Niemals mitten in einen bestehenden Abschnitt
+**Insert position:**
+- After the project-specific context (architecture, commands)
+- Before project-specific exceptions if present
+- Never in the middle of an existing section
 
-## Schritt 2b — Update (Block bereits vorhanden)
+## Step 2b — Update (block already present)
 
-1. **Projekt-Ausnahmen sichern:** Alles innerhalb des Blocks das mit `[Ausnahme:` beginnt
-   oder manuell annotiert wurde → zwischenspeichern
+1. **Save project exceptions:** Everything inside the block that begins with `[Exception:`
+   or was manually annotated → store temporarily
 
-2. **Alten Block ersetzen:** Exakt den Text zwischen `DEV-BEST-PRACTICES:START` und
-   `DEV-BEST-PRACTICES:END` (inkl. Marker) durch den neuen Block ersetzen
+2. **Replace old block:** Replace exactly the text between `DEV-BEST-PRACTICES:START` and
+   `DEV-BEST-PRACTICES:END` (including markers) with the new block
 
-3. **Projekt-Ausnahmen wiederherstellen:** Gesicherte Ausnahmen ans Ende des neuen Blocks
-   einfügen (vor `DEV-BEST-PRACTICES:END`), mit Kommentar `<!-- Projekt-Ausnahmen -->`
+3. **Restore project exceptions:** Insert saved exceptions at the end of the new block
+   (before `DEV-BEST-PRACTICES:END`), with comment `<!-- Project exceptions -->`
 
-4. **Version-Marker aktualisieren:**
+4. **Update version marker:**
    ```text
-   <!-- Version: essential-rules.md @ <neues Datum> | Umfang: essential | Vorher: <altes Datum> -->
+   <!-- Version: essential-rules.md @ <new date> | Scope: essential | Previous: <old date> -->
    ```
 
-**Was beim Update nie angefasst wird:**
-- Alles außerhalb der Marker-Kommentare
-- `[Ausnahme: …]` Blöcke innerhalb des alten Blocks
-- Projektbeschreibung, Commands, Architektur-Notizen
+**What is never touched during an update:**
+- Everything outside the marker comments
+- `[Exception: …]` blocks inside the old block
+- Project description, commands, architecture notes
 
-## Schritt 3 — Vorschau & Bestätigung
+## Step 3 — Preview & Confirmation
 
-**Vor dem Schreiben zeigen:**
+**Show before writing:**
 
 ```text
-Modus: [Erstinstallation / Update]
-Datei: ./CLAUDE.md
-Umfang: essential-rules.md (78 Zeilen)
+Mode: [Initial install / Update]
+File: ./CLAUDE.md
+Scope: essential-rules.md (78 lines)

-[Update] Gesicherte Projekt-Ausnahmen: Z Stück
+[Update] Old block: Version from <date>, X lines

+[Update] Saved project exceptions: Z items
 
-Änderungen außerhalb des Blocks: keine
+Changes outside the block: none
 
-Fortfahren? (ja/nein)
+Proceed? (yes/no)
 ```
 
-Nach dem Schreiben:
-- `✓ Block [eingefügt / aktualisiert]: X Regeln, Y Sections`
-- Bei Update: `Projekt-Ausnahmen erhalten: Z Stück`
-- Nächster Schritt: `check-drift` läuft automatisch zur Verifikation
-
-## Regeln
-- Nur schreiben nach Bestätigung.
-- Niemals Inhalt außerhalb der Marker anfassen.
-- Projekt-Ausnahmen immer erhalten — sie sind bewusste Abweichungen, kein Fehler.
-- Falls `CLAUDE.md` nicht existiert: Datei mit Projekt-Placeholder + Rules-Block anlegen.
-- Nach jedem Update den `check-drift` Skill aufrufen um zu verifizieren dass der neue
-  Block korrekt eingefügt wurde.
+After writing:
+- `✓ Block [inserted / updated]: X rules, Y sections`
+- On update: `Project exceptions preserved: Z items`
+- Next step: `check-drift` runs automatically for verification
+
+## Rules
+- Only write after confirmation.
+- Never touch content outside the markers.
+- Always preserve project exceptions — they are deliberate deviations, not errors.
+- If `CLAUDE.md` does not exist: create file with project placeholder + rules block.
+- After every update call the `check-drift` skill to verify the new block
+  was inserted correctly.

-- `reference/` wird nie verändert — nur `claude/` und `essential-rules.md`.
-- Kondensierung bewahren: `claude/`-Files sollen knapp bleiben. Keine langen Erklärungen rüberkopieren.
-- Inhaltliche Korrektheit vor Vollständigkeit: lieber eine Regel weglassen als eine falsch kondensieren.
+## Rules
+- No automatic changes without confirmation.
+- `reference/` is never changed — only `claude/` and `essential-rules.md`.
+- Preserve condensation: `claude/` files should stay concise. Do not copy over long explanations.
+- Content correctness over completeness: better to omit a rule than condense it incorrectly.

-
-1. Bestimme die **Regelquelle** in dieser Reihenfolge:
-   a) Regel-Files dieses Repos, falls erreichbar (`claude/essential-rules.md`,
+| `Dockerfile` / `docker-compose.yml` | Container context, services, network |
+| `.github/workflows/*.yml` | CI pipeline present, which steps |
+| `CLAUDE.md` of the project | Documented exceptions, known constraints |
+| Lock files (`pnpm-lock.yaml`, `uv.lock`, `package-lock.json`) | Actually used versions |
+
+**Derive from discovery (do not ask):**
+- **Team size:** Solo if no team context in `CLAUDE.md` → ASVS L1 default
+- **ASVS level:** L1 for solo/prototype, L2 when auth/payment/sensitive data is visible, L3 only if explicit
+- **Compliance:** GDPR if EU users in description or privacy concept present
+- **Deployment target:** derive from Dockerfile/CI (container, serverless, classic)
+
+Only ask if discovery yields no clear answer (e.g., no config files at all).
+Report discovered values compactly to the user: `Stack: Next.js 14 + TypeScript | DB: Postgres | CI: GitHub Actions | ASVS: L2`.
+
+1. Determine the **rule source** in this order:
+   a) Rule files of this repo, if reachable (`claude/essential-rules.md`,
       `claude/app-rules.md`, `claude/github-rules.md`, `claude/architecture-rules.md`;
-      Tiefe bei Bedarf aus `reference/*.md`).
-   b) sonst die `CLAUDE.md` des Ziel-Projekts (enthält oft die kopierten Essential-Rules).
-   c) sonst Default-Standards (12-Factor, ASVS L2, DORA).
-   Nenne dem Nutzer, welche Quelle aktiv ist.
-2. Dokumentierte **Ausnahmen** aus `CLAUDE.md`/`REVIEW.md` übernehmen (z.B. absichtlich
-   öffentliche Routes), damit Re-Runs konsistent bleiben.
-
-## Schritt 1 - Plan zuerst
-Skizziere kurz, welche sechs Subagenten mit welchem Scope laufen, welche Regelquelle
-gilt und welche Tools fehlen (z.B. keine CI-Historie -> DORA nur Schätzung). Erst nach
-kurzer Bestätigung ausführen.
-
-## Schritt 2 - Sechs Subagenten PARALLEL
-Alle sechs als Task-Subagenten in EINER Nachricht starten. Jeder gibt eine
-**komprimierte** Befundliste zurück (keine Roh-Dumps), Hauptkontext bleibt sauber.
-
-Jeder Befund:
-`Titel · Datei:Zeile · Severity (Critical/High/Medium/Low) · Confidence (1-10) ·
-verletzte Regel (Datei -> Section) · Fix · Aufwand (S<30min / M<2h / L>2h)`.
-
-### Agent 1 - Architektur & 12-Factor
-Maßstab: `architecture-rules.md` (+ `reference/architecture-best-practices.md`).
-Prüfe: Feature-basierte Struktur, Schichtung (Routes->Service->Data Access),
-Monolith-First, die 12 Faktoren (Config in Env, stateless, Logs auf Stdout, Port
-Binding, Disposability), Docker-Architektur (127.0.0.1-Bind, Health Checks, Limits).
+      depth from `reference/*.md` as needed).
+   b) Otherwise the `CLAUDE.md` of the target project (often contains the copied essential rules).
+   c) Otherwise default standards (12-Factor, ASVS L2, DORA).
+   Tell the user which source is active.
+2. Carry over documented **exceptions** from `CLAUDE.md`/`REVIEW.md` (e.g., intentionally
+   public routes) so re-runs remain consistent.
+
+## Step 1 - Plan First
+Briefly outline which six sub-agents run with which scope, which rule source
+applies, and which tools are missing (e.g., no CI history → DORA estimate only).
+Only proceed after a brief confirmation.
+
+## Step 2 - Six Sub-Agents IN PARALLEL
+Start all six as task sub-agents in ONE message. Each returns a
+**compressed** finding list (no raw dumps); main context stays clean.
+
+Each finding:
+`Title · File:Line · Severity (Critical/High/Medium/Low) · Confidence (1-10) ·
+violated rule (File -> Section) · Fix · Effort (S<30min / M<2h / L>2h)`.
+
+### Agent 1 - Architecture & 12-Factor
+Standard: `architecture-rules.md` (+ `reference/architecture-best-practices.md`).
+Check: feature-based structure, layering (Routes→Service→Data Access),
+monolith-first, the 12 factors (config in env, stateless, logs to stdout, port
+binding, disposability), Docker architecture (127.0.0.1 binding, health checks, limits).
 
 ### Agent 2 - Security (ASVS 5.0 + Top 10)
-Maßstab: `app-rules.md` Security-Sections (+ `reference/app-best-practices.md`).
-Prüfe gegen ZIEL-ASVS-LEVEL: Security Headers (CSP/HSTS/…), Auth an 3 Schichten
-(v.a. Data Access Layer), Input-Validierung (Zod/Pydantic), Prepared Statements,
-DOM-XSS, Secrets-Handling, Cookie-Flags, CORS, File-Uploads, PostgreSQL-Hardening.
-Tooling-Soll: gitleaks, bandit/ruff-S, semgrep, pip-audit, trivy.
-Falls die offizielle `/security-review`-Komponente installiert ist, darf dieser Agent
-sie nutzen statt zu duplizieren.
-**False-Positive-Filter:** nur Confidence >= 7. Fehlende UUID-Validierung,
-Resource-Leaks und Env-Var-abhängige Angriffe gelten NICHT als Schwachstelle.
-Fehlende Audit-Logs → als ⚪ COMPLIANCE melden (ISO 27001 A.8.15 / GDPR Art. 32),
-nicht als Security HIGH/CRITICAL.
-
-### Agent 3 - Code-Qualität
-Default-Schwellwerte (anpassbar, gehören perspektivisch in ein eigenes Regel-File):
-Komplexität/Funktion Warnung >10 / Fail >20; Funktion >50 Zeilen; Datei >400 Zeilen;
-Duplikation >3 %; Verschachtelung >4. Plus Naming, toter Code, fehlende Typisierung.
-
-### Agent 4 - Tests & Zuverlässigkeit
-Maßstab: `architecture-rules.md` (Testing-Strategie) + `github-rules.md` (Testing).
-Test-Pyramide einschätzen; Coverage messen falls Tooling da (Soll: 70-80 % Lines,
-kritische Pfade ~100 %). Ungetestete kritische Pfade (Auth, Payment, Datenmutationen)
-explizit auflisten. Flaky/Skip/Smoke-only markieren.
+Standard: `app-rules.md` security sections (+ `reference/app-best-practices.md`).
+Check against TARGET ASVS LEVEL: security headers (CSP/HSTS/…), auth at 3 layers
+(especially data access layer), input validation (Zod/Pydantic), prepared statements,
+DOM XSS, secrets handling, cookie flags, CORS, file uploads, PostgreSQL hardening.
+Tooling requirements: gitleaks, bandit/ruff-S, semgrep, pip-audit, trivy.
+If the official `/security-review` component is installed, this agent may use it
+instead of duplicating the work.
+**False-positive filter:** only confidence >= 7. Missing UUID validation,
+resource leaks, and env-var-dependent attacks do NOT count as vulnerabilities.
+Missing audit logs → report as ⚪ COMPLIANCE (ISO 27001 A.8.15 / GDPR Art. 32),
+not as Security HIGH/CRITICAL.
+
+### Agent 3 - Code Quality
+Default thresholds (adjustable, should eventually belong in a dedicated rule file):
+Complexity/function warning >10 / fail >20; function >50 lines; file >400 lines;
+duplication >3%; nesting >4. Plus naming, dead code, missing type annotations.
+
+### Agent 4 - Tests & Reliability
+Standard: `architecture-rules.md` (testing strategy) + `github-rules.md` (testing).
+Assess test pyramid; measure coverage if tooling is available (target: 70-80% lines,
+critical paths ~100%). Explicitly list untested critical paths (auth, payment, data mutations).
+Flag flaky/skip/smoke-only tests.
 
 ### Agent 5 - CI/CD & Delivery (DORA)
-Maßstab: `github-rules.md` (Pipeline, Branch Protection, Scanning).
-Prüfe: Build/Lint/Type-Check/Test/gitleaks pro PR? semgrep+trivy mit exit-code 1?
-Branch Protection auf main? Renovate? Deployment reproduzierbar + Rollback?
-Lokalisiere die DORA-Hebel (Deployment Frequency, Lead Time for Changes,
-Change Failure Rate, Failed Deployment Recovery Time). **Ehrlich kennzeichnen,**
-welche Werte aus CI-Historie echt messbar sind und welche nur geschätzt.
-
-### Agent 6 - Observability & Betrieb (Bash erlaubt)
-Maßstab: `app-rules.md` (Logging/Monitoring/Observability) + `reference/`.
-Prüfe: strukturiertes JSON-Logging (Pino/structlog), keine Secrets in Logs, Sentry,
-Uptime, vier goldene Signale, Health/Ready-Endpoints, OpenTelemetry-Bereitschaft.
-Dependency-Audit-CLI ausführen (`npm audit`/`pip-audit`) und zusammenfassen.
-Container-Hygiene falls Dockerfile (non-root, Digest-Pin, Multi-Stage, `--check`).
-
-## Schritt 3 - Konsolidieren & Report
-1. Alle Befunde zu EINER nach Severity sortierten Liste mergen; Security <7 verwerfen.
-2. Pro Achse eine Ampel (gruen/gelb/rot) + ein Satz Begründung.
-3. Fix-Reihenfolge: geteilte Utilities/Security zuerst, dann Refactors, dann Tests, dann Kosmetik.
-4. Schreibe Report nach `./review-app-report.md` mit Tabelle:
-   `Achse | Ampel | #Critical | #High | wichtigste verletzte Regel`.
-
-## Regeln
-- Keine spekulativen Befunde. Nur mit Datei:Zeile-Bezug oder klar belegbarer Lücke.
-  Unsicheres als "[zu verifizieren]" kennzeichnen.
-- Jeder Befund nennt die konkrete verletzte Regel (Datei -> Section), nicht nur ein generisches Prinzip.
-- **Nichts automatisch fixen.** Erst Report, dann auf Nachfrage gezielt umsetzen.
-- Verifikation vor "fertig": Würde ein Staff-Engineer diesen Report freigeben?
-- Neue bewusste Ausnahmen, die im Lauf auftauchen, der `CLAUDE.md` des Ziel-Projekts vorschlagen.
+Standard: `github-rules.md` (pipeline, branch protection, scanning).
+Check: build/lint/type-check/test/gitleaks per PR? semgrep+trivy with exit-code 1?
+Branch protection on main? Renovate? Deployment reproducible + rollback?
+Locate the DORA levers (Deployment Frequency, Lead Time for Changes,
+Change Failure Rate, Failed Deployment Recovery Time). **Honestly mark**
+which values are truly measurable from CI history and which are estimates only.
+
+### Agent 6 - Observability & Operations (Bash allowed)
+Standard: `app-rules.md` (Logging/Monitoring/Observability) + `reference/`.
+Check: structured JSON logging (Pino/structlog), no secrets in logs, Sentry,
+uptime, four golden signals, health/ready endpoints, OpenTelemetry readiness.
+Run dependency audit CLI (`npm audit`/`pip-audit`) and summarize.
+Container hygiene if Dockerfile present (non-root, digest pin, multi-stage, `--check`).
+
+## Step 3 - Consolidate & Report
+1. Merge all findings into ONE list sorted by severity; discard security findings < 7.
+2. Per axis: a traffic light (green/yellow/red) + one sentence of rationale.
+3. Fix order: shared utilities/security first, then refactors, then tests, then cosmetics.
+4. Write report to `./review-app-report.md` with table:
+   `Axis | Traffic light | #Critical | #High | most important violated rule`.
+
+## Rules
+- No speculative findings. Only with File:Line reference or clearly evidenced gap.
+  Uncertain findings marked as "[to verify]".
+- Every finding names the concrete violated rule (File -> Section), not just a generic principle.
+- **Fix nothing automatically.** Report first, then implement selectively on request.
+- Verification before "done": Would a staff engineer sign off on this report?
+- New deliberate exceptions discovered during the run: propose adding them to the target project's `CLAUDE.md`.

-## Regeln
+## Rules
 
-- Keine spekulativen Befunde. Nur mit konkretem Bezug zum vorgelegten Design oder
-  klar belegbarer Lücke. Unsicheres als `[zu verifizieren]` kennzeichnen.
-- Jeder Befund nennt die konkrete verletzte Guideline (HAX G-Nr. / PAIR P-Nr. / CHI P-Nr. / NNG), nicht nur ein generisches Prinzip.
-- **Nichts automatisch fixen.** Erst Report, dann auf Nachfrage gezielt umsetzen.
-- Accessibility-Probleme die gegen EU Accessibility Act / BFSG verstoßen → immer als **High** oder **Critical** melden.
-- Anti-Patterns nicht doppelt melden: Dimension 6 = AI UX Anti-Patterns, Dimension 7 = Manipulation / Dark Patterns — diese beiden Kategorien sind bewusst getrennt.
-- Positive Befunde explizit erwähnen — was funktioniert gut und warum. UX-Review ist kein reiner Bug-Report.
+- No speculative findings. Only with concrete reference to the submitted design or
+  a clearly demonstrable gap. Mark uncertain items as `[to be verified]`.
+- Every finding names the specific violated guideline (HAX G-No. / PAIR P-No. / CHI P-No. / NNG), not just a generic principle.
+- **Do not auto-fix anything.** Report first, then implement on request.
+- Accessibility problems that violate the EU Accessibility Act / BFSG → always report as **High** or **Critical**.
+- Do not double-report anti-patterns: Dimension 6 = AI UX Anti-Patterns, Dimension 7 = Manipulation / Dark Patterns — these two categories are deliberately separate.
+- Explicitly mention positive findings — what works well and why. A UX review is not a pure bug report.

-**Sprache & Runtime:**
-- `package.json` → Node.js/TypeScript, Framework (Next.js, Express, Fastify, NestJS …)
-- `pyproject.toml` / `requirements.txt` → Python, Framework (FastAPI, Django, Flask …)
+**Language & Runtime:**

+- `pyproject.toml` / `requirements.txt` → Python, framework (FastAPI, Django, Flask …)
 - `go.mod` → Go
 - `Cargo.toml` → Rust
 - `pom.xml` / `build.gradle` → Java/Kotlin
 
-**Deployment & Infrastruktur:**
-- `Dockerfile` / `docker-compose.yml` → Container-Kontext, Netzwerk-Aliase, Volumes
-- `.github/workflows/` → CI-Pipeline, Build-Schritte
-- `CLAUDE.md` des Projekts → dokumentierte Ausnahmen, bekannte Probleme
+**Deployment & Infrastructure:**
+- `Dockerfile` / `docker-compose.yml` → container context, network aliases, volumes
+- `.github/workflows/` → CI pipeline, build steps
+- Project `CLAUDE.md` → documented exceptions, known issues
 
-**Fehler-Kontext vom Nutzer erfassen:**
-- Fehlermeldung / Stack Trace (falls nicht gegeben: einmal nachfragen)
-- Wann tritt er auf (Start / Laufzeit / Build / Test)?
-- Reproduzierbar oder intermittierend?
-- Was hat sich zuletzt geändert?
+**Gather error context from the user:**
+- Error message / stack trace (if not provided: ask once)
+- When does it occur (startup / runtime / build / test)?
+- Reproducible or intermittent?
+- What changed recently?
 
-## Schritt 1 — Fehler klassifizieren
+## Step 1 — Classify the Error
 
-Ordne den Fehler einer Kategorie zu und passe die Analyse an:
+Assign the error to a category and adapt the analysis:
 
-| Kategorie | Typische Ursachen | Wo suchen |
+| Category | Typical causes | Where to look |
 |---|---|---|
-| **Import / Dependency** | falsche Version, fehlender Peer-Dep, zirkulärer Import | package.json / lock file, Import-Reihenfolge |
-| **Konfiguration** | fehlende Env-Var, falscher Pfad, Type Mismatch in Config | .env, config-Files, Startup-Logs |
-| **Netzwerk / API** | falscher Port, CORS, Auth-Header fehlt, Timeout | Docker-Netzwerk, Proxy-Config, Request-Headers |
-| **Datenbank** | Migration nicht gelaufen, Connection Pool erschöpft, Query-Fehler | Migration-History, Connection-String, Query-Logs |
-| **Async / Concurrency** | Race Condition, unbehandeltes Promise, Deadlock | Event Loop, async/await Kette, Locking |
-| **Type / Schema** | Nullpointer, Schema-Mismatch, falsches Format | Typen, Validierung (Zod/Pydantic), Serialisierung |
-| **Build / Compile** | Transpile-Fehler, fehlende Typen, Tree-Shaking | tsconfig, Bundler-Config, Import-Pfade |
-| **Umgebungsunterschied** | "funktioniert lokal" → Container/CI anders | Env-Vars, Node/Python-Version, Pfad-Trennzeichen |
+| **Import / Dependency** | Wrong version, missing peer dep, circular import | package.json / lock file, import order |
+| **Configuration** | Missing env var, wrong path, type mismatch in config | .env, config files, startup logs |
+| **Network / API** | Wrong port, CORS, missing auth header, timeout | Docker network, proxy config, request headers |
+| **Database** | Migration not run, connection pool exhausted, query error | Migration history, connection string, query logs |
+| **Async / Concurrency** | Race condition, unhandled promise, deadlock | Event loop, async/await chain, locking |
+| **Type / Schema** | Null pointer, schema mismatch, wrong format | Types, validation (Zod/Pydantic), serialization |
+| **Build / Compile** | Transpile error, missing types, tree-shaking | tsconfig, bundler config, import paths |
+| **Environment difference** | "works locally" → container/CI differs | Env vars, Node/Python version, path separators |
 
-## Schritt 2 — Root-Cause-Analyse
+## Step 2 — Root Cause Analysis
 
-1. **Lese die relevanten Dateien** (nicht alle — nur die, die zur Fehler-Kategorie passen)
-2. **Trace den Fehler-Pfad** von der Fehlermeldung rückwärts durch die Aufrufkette
-3. **Prüfe die häufigsten Ursachen** für diesen Stack + diese Kategorie
-4. **Formuliere 1-3 Hypothesen** mit Konfidenz (hoch/mittel/niedrig) und Begründung
+1. **Read the relevant files** (not all — only those matching the error category)
+2. **Trace the error path** from the error message backward through the call chain
+3. **Check the most common causes** for this stack + this category
+4. **Formulate 1–3 hypotheses** with confidence (high/medium/low) and rationale
 
-Stack-spezifische Checks (nur wenn relevant):
+Stack-specific checks (only when relevant):
 
 **Next.js / React:**
-- Server vs. Client Component Grenze verletzt?
-- `use client` / `use server` Direktive korrekt?
-- Hydration-Mismatch (Server-/Client-Render unterschiedlich)?
-- `.env.local` vs. `.env.production` — Variable exposed?
+- Server vs. client component boundary violated?
+- `use client` / `use server` directive correct?
+- Hydration mismatch (server/client render different)?
+- `.env.local` vs. `.env.production` — variable exposed?
 
 **FastAPI / Python:**
-- Pydantic-Schema-Mismatch (v1 vs. v2 API)?
-- Async-Fehler: `await` fehlt, sync-Funktion in async-Kontext?
-- Dependency Injection fehlgeschlagen (`Depends()`)?
-- CORS-Middleware Reihenfolge falsch?
+- Pydantic schema mismatch (v1 vs. v2 API)?
+- Async error: missing `await`, sync function in async context?
+- Dependency injection failed (`Depends()`)?
+- CORS middleware order wrong?
 
 **Docker / Container:**
-- Service-Name im Compose-Netzwerk falsch referenziert?
-- Volume-Mount überschreibt kompilierte Artefakte?
-- Health-Check blockiert Startup-Reihenfolge?
-- Port 0.0.0.0 vs. 127.0.0.1 (nur im Container erreichbar)?
+- Service name in Compose network incorrectly referenced?
+- Volume mount overwrites compiled artifacts?
+- Health check blocking startup order?
+- Port 0.0.0.0 vs. 127.0.0.1 (only reachable inside container)?

-- Wenn der Fehler nicht eindeutig lokalisierbar: zwei gezielte Diagnose-Schritte vorschlagen,
-  nicht alle möglichen Ursachen aufzählen.
-- Automatisch fixen nur wenn der Nutzer es explizit verlangt.
+## Rules
+- No checklist-based approach. Only what is relevant for this error.
+- Do not offer multiple fix variants when one clearly dominates — recommend directly.
+- If the error cannot be clearly localized: suggest two targeted diagnostic steps,
+  do not enumerate all possible causes.
+- Auto-fix only when the user explicitly requests it.

-1. Alle relevanten Ressourcen auflisten (fuer den betroffenen Stack)
-2. Pro Ressource: U, S, E messen (Tools aus obiger Tabelle)
-3. Engpass identifizieren:
-   ├─ Utilization nahe 100%  → Ressource ist saturiert
-   ├─ Saturation > 0         → Warteschlange bildet sich
-   └─ Errors > 0             → Sofort untersuchen
-4. Ressource mit hoechster Saturation oder Errors = primaerer Bottleneck
-5. Tiefer analysieren mit profilierungs-spezifischen Tools (Flamegraph)
+1. List all relevant resources (for the affected stack)
+2. Per resource: measure U, S, E (tools from above table)
+3. Identify bottleneck:
+   ├─ Utilization near 100%  → resource is saturated
+   ├─ Saturation > 0         → queue is forming
+   └─ Errors > 0             → investigate immediately
+4. Resource with highest saturation or errors = primary bottleneck
+5. Analyze deeper with profiling-specific tools (flamegraph)

-## Schritt 1 — Aufgabe klassifizieren
+## Step 1 — Classify the Task
 
-**Visuelles Problem beheben:**
-Lies die betroffene Komponente, identifiziere den Styling-Konflikt.
-Häufige Ursachen je nach Stack:
+**Fix a visual problem:**
+Read the affected component, identify the styling conflict.
+Common causes by stack:
 
 *Tailwind:*
-- Class-Reihenfolge Konflikt (letztes `cn()` gewinnt)
-- Purge/Safelist fehlt für dynamisch gebaute Klassen
-- Dark-Mode-Klassen (`dark:`) ohne `darkMode: 'class'` in Config
-- Tailwind v3 vs. v4 API-Unterschiede (v4: `@import "tailwindcss"`, neue Utility-Namen)
+- Class order conflict (last `cn()` wins)
+- Purge/safelist missing for dynamically built classes
+- Dark mode classes (`dark:`) without `darkMode: 'class'` in config
+- Tailwind v3 vs. v4 API differences (v4: `@import "tailwindcss"`, new utility names)
 
 *CSS Modules:*
-- `:global()` vs. lokaler Scope unklar
-- Kompilierter Klassenname vs. erwarteter Name
-- Cascade-Konflikt mit globalen Styles
+- `:global()` vs. local scope unclear
+- Compiled class name vs. expected name
+- Cascade conflict with global styles
 
 *CSS-in-JS (Emotion/SC):*
-- SSR-Hydration-Mismatch (Klassen-IDs unterschiedlich)
-- Theme-Context nicht verfügbar
-- `css` vs. `styled` in Server Components (Next.js App Router → inkompatibel!)
+- SSR hydration mismatch (class IDs differ)
+- Theme context unavailable
+- `css` vs. `styled` in Server Components (Next.js App Router → incompatible!)
 
-*Komponenten-Library-Override:*
-- MUI: `sx` prop vs. `styled()` vs. theme override — welche Ebene?
-- shadcn: Klassen direkt in der Komponente überschreiben vs. `cn()` verwenden
-- Radix: `asChild` Pattern für Styling-Delegation
+*Component library override:*
+- MUI: `sx` prop vs. `styled()` vs. theme override — which level?
+- shadcn: override classes directly in component vs. use `cn()`
+- Radix: `asChild` pattern for styling delegation
 
-**CSS-Architektur verbessern:**
-Bewertet das vorhandene System auf:
-- Design-Token-Konsistenz (hardcodierte Werte statt Tokens?)
-- Responsive-Strategie (mobile-first? Breakpoints konsistent?)
-- Dark-Mode-Implementierung (CSS Custom Properties empfohlen)
-- Bundle-Size (ungenutzte CSS-Regeln, PurgeCSS-Konfiguration)
+**Improve CSS architecture:**
+Evaluate the existing system for:
+- Design token consistency (hardcoded values instead of tokens?)
+- Responsive strategy (mobile-first? breakpoints consistent?)
+- Dark mode implementation (CSS Custom Properties recommended)
+- Bundle size (unused CSS rules, PurgeCSS configuration)
 
-**Komponente neu stylen:**
-Schreibt Styling im vorhandenen System-Stil:
-- Nutzt vorhandene Tokens/Variablen statt neue einzuführen
-- Folgt vorhandenen Naming-Konventionen
-- Responsive nach vorhandenem Breakpoint-System
+**Restyle a component:**
+Write styling in the existing system style:
+- Use existing tokens/variables instead of introducing new ones
+- Follow existing naming conventions
+- Responsive using the existing breakpoint system
 
-## Schritt 2 — Lösung erarbeiten
+## Step 2 — Develop Solution
 
-**Design-Token-First-Prinzip:**
-Vor jedem Styling-Vorschlag prüfen: Gibt es einen vorhandenen Token der passt?
-→ Token verwenden, keinen neuen Wert einführen.
+**Design-token-first principle:**
+Before every styling suggestion check: is there an existing token that fits?
+→ Use the token, do not introduce a new value.
 
-**Konsistenz-Check:**
-Ähnliche Komponenten im Projekt suchen — gleiche Muster verwenden, keine neuen erfinden.
+**Consistency check:**
+Look for similar components in the project — use the same patterns, do not invent new ones.
 
-**Responsive-Strategie:**
-- Mobile-First (min-width) außer das Projekt nutzt bereits Desktop-First (max-width)
-- Vorhandene Breakpoints aus Config/Tokens verwenden
+**Responsive strategy:**
+- Mobile-first (min-width) unless the project already uses desktop-first (max-width)
+- Use existing breakpoints from config/tokens
 
-**Stack-spezifische Best Practices:**
+**Stack-specific best practices:**
 
 *Tailwind + shadcn:*
 ```tsx
-// Gut: cn() für konditionelle Klassen
+// Good: cn() for conditional classes
 className={cn("base-classes", condition && "conditional-class", className)}
 
-// Schlecht: String-Interpolation
+// Bad: string interpolation
 className={`base-classes ${condition ? 'class-a' : ''}`}
 ```
 
 *CSS Modules + SCSS:*
 ```scss
-// Gut: Composition für Varianten
+// Good: composition for variants
 .button { composes: base from './base.module.scss'; }
 
-// Gut: CSS Custom Properties für Theming
+// Good: CSS Custom Properties for theming
 .card { background: var(--color-surface); }
 ```
 
-*MUI Theme Override (nie inline sx für globale Muster):*
+*MUI Theme Override (never inline sx for global patterns):*
 ```ts
-// Gut: Theme-Level Override
+// Good: theme-level override
 components: { MuiButton: { styleOverrides: { root: { borderRadius: 8 } } } }

-## Regeln
-- Kein Stack-Wechsel vorschlagen (Tailwind durch SCSS ersetzen etc.) außer der Nutzer fragt explizit.
-- Keine neuen Design-Tokens einführen wenn vorhandene passen.
-- CSS-in-JS (Emotion, Styled Components) in Next.js App Router explizit als problematisch markieren — Server Components sind inkompatibel.
-- Keine `!important` Lösung außer als letzter Ausweg mit Erklärung warum.
-- Automatisch in Dateien schreiben nur wenn der Nutzer es explizit verlangt.
+## Rules
+- Do not suggest switching stacks (replacing Tailwind with SCSS etc.) unless the user explicitly asks.
+- Do not introduce new design tokens when existing ones fit.
+- CSS-in-JS (Emotion, Styled Components) in Next.js App Router explicitly mark as problematic — Server Components are incompatible.
+- No `!important` solution except as a last resort with explanation why.
+- Auto-write to files only when the user explicitly requests it.

-**Kritische Pfade die IMMER Tests brauchen:**
-- Authentifizierung & Autorisierung (Login, Token-Validierung, Permission-Checks)
-- Datenmutationen (Create/Update/Delete mit Validierung)
-- Externe Integrationen (API-Calls, Webhooks, Payment)

-**Stack-spezifische Test-Empfehlungen:**
+**Stack-specific test recommendations:**
 
 *Next.js / React:*
-- Vitest + React Testing Library für Komponenten (kein Enzyme)

-- Snapshot-Tests sparsam — nur für stabile UI-Komponenten
+- Vitest + React Testing Library for components (not Enzyme)
+- Server Actions: integration test with real DB access, not mocked
+- `playwright` for critical user flows (login, checkout)
+- Snapshot tests sparingly — only for stable UI components
 
 *FastAPI / Python:*
-- `pytest` + `httpx.AsyncClient` für API-Endpoints
-- `pytest-asyncio` für async-Tests
-- Echte DB für Integration-Tests (`pytest-postgresql` / SQLite in-memory)
-- `factory_boy` für Test-Fixtures statt manuelle Fixtures
+- `pytest` + `httpx.AsyncClient` for API endpoints
+- `pytest-asyncio` for async tests
+- Real DB for integration tests (`pytest-postgresql` / SQLite in-memory)

-- Test-DB via Docker oder in-memory (bessere Isolation als Mocking)
+- Vitest or Jest + Supertest for HTTP tests
+- Test DB via Docker or in-memory (better isolation than mocking)
 
-*Generell:*
-- Keine Mock-Kaskaden für eigene Infrastruktur — echte DB im Test ist zuverlässiger

+*General:*
+- No mock cascades for own infrastructure — real DB in test is more reliable
+- Mock external APIs (Stripe, SendGrid …) — but with realistic payloads
 
-## Schritt 2 — Tests schreiben oder verbessern
+## Step 2 — Write or Improve Tests
 
-Je nach Anfrage des Nutzers:
+Depending on the user's request:
 
-**Neue Tests generieren:**
-1. Identifiziere die zu testende Unit (Funktion / Endpoint / Komponente)
-2. Bestimme sinnvolle Testfälle: Happy Path, Edge Cases, Fehler-Szenarien
-3. Schreibe Tests im vorhandenen Format (Dateinamen-Konvention, Import-Stil, Fixture-Pattern)
-4. Keine Duplikation von vorhandenen Tests
+**Generate new tests:**
+1. Identify the unit to test (function / endpoint / component)
+2. Determine sensible test cases: happy path, edge cases, error scenarios
+3. Write tests in the existing format (filename convention, import style, fixture pattern)
+4. No duplication of existing tests
 
-**Test-Strategie entwerfen:**
-1. Lücken-Analyse: Was ist kritisch und ungetestet?
-2. Priorisierung: Auth > Datenmutationen > Business Logic > UI
-3. Aufwandsschätzung pro Bereich (S/M/L)
-4. Roadmap: Was zuerst, was kann warten?
+**Design test strategy:**
+1. Gap analysis: what is critical and untested?
+2. Prioritization: auth > data mutations > business logic > UI
+3. Effort estimate per area (S/M/L)
+4. Roadmap: what first, what can wait?
 
-**Vorhandene Tests verbessern:**
-1. Flaky Tests: Timing-Abhängigkeiten, externe State-Abhängigkeiten identifizieren
-2. Zu breite Mocks: Was wird gemockt das nicht gemockt werden sollte?
-3. Test-Dopplung: Gleiche Logik in Unit + Integration + E2E → nur auf einer Ebene
-4. Fehlende Assertions: Tests die nur "kein Fehler" prüfen statt Verhalten
+**Improve existing tests:**
+1. Flaky tests: identify timing dependencies, external state dependencies
+2. Overly broad mocks: what is mocked that should not be mocked?
+3. Test duplication: same logic in unit + integration + E2E → only at one level
+4. Missing assertions: tests that only check "no error" instead of behavior

-## Regeln
-- Tests schreiben die Verhalten prüfen, nicht Implementierungsdetails.
-- Kein Test-Code der komplexer ist als der Code den er testet.
-- `// TODO: add more tests` niemals stehen lassen — entweder schreiben oder als Lücke dokumentieren.
-- Automatisch in Dateien schreiben nur wenn der Nutzer es explizit verlangt.
-- Coverage als Metrik nennen aber nicht als Ziel — schlecht geschriebene Tests die Coverage erhöhen sind wertlos.
+## Rules
+- Write tests that check behavior, not implementation details.
+- No test code that is more complex than the code it tests.
+- Never leave `// TODO: add more tests` — either write them or document as a gap.
+- Auto-write to files only when the user explicitly requests it.
+- Cite coverage as a metric but not as a goal — poorly written tests that increase coverage are worthless.

-### CSP – Theorie & Hintergrund
+### CSP – Theory & Background
 
-**Was ist CSP?** Content Security Policy ist ein HTTP-Response-Header der dem Browser sagt, welche Ressourcen (Scripts, Styles, Bilder, Fonts, etc.) von welchen Quellen geladen werden dürfen. Alles was nicht explizit erlaubt ist, wird blockiert.
+**What is CSP?** Content Security Policy is an HTTP response header that tells the browser which resources (scripts, styles, images, fonts, etc.) may be loaded from which sources. Everything not explicitly allowed is blocked.
 
-**Das Problem ohne CSP:** Ohne CSP kann ein Angreifer, der XSS (Cross-Site Scripting) in deine Seite einschleust, beliebigen JavaScript-Code ausführen – Daten stehlen, Sessions übernehmen, Keylogger einbauen. CSP ist die letzte Verteidigungslinie: Selbst wenn XSS gelingt, blockiert der Browser das Nachladen von externen Scripts oder das Ausführen von Inline-Code.
+**The problem without CSP:** Without CSP, an attacker who injects XSS (Cross-Site Scripting) into your page can execute arbitrary JavaScript code — steal data, hijack sessions, install keyloggers. CSP is the last line of defense: even if XSS succeeds, the browser blocks loading external scripts or executing inline code.
 
-**Wie funktioniert es?**
+**How does it work?**
 
 ```text
-1. Server sendet Response mit Header:
+1. Server sends response with header:
    Content-Security-Policy: script-src 'self'; style-src 'self'
 
-2. Browser parsed die HTML-Seite
+2. Browser parses the HTML page
 
-3. Für jede Ressource prüft der Browser:
-   - <script src="https://evil.com/steal.js">  → BLOCKIERT (nicht 'self')
-   - <script src="/app.js">                    → ERLAUBT ('self')
-   - <script>alert('xss')</script>             → BLOCKIERT (kein 'unsafe-inline')
-   - <img src="https://tracker.com/pixel.gif"> → BLOCKIERT (falls img-src: 'self')
+3. For each resource the browser checks:
+   - <script src="https://evil.com/steal.js">  → BLOCKED (not 'self')
+   - <script src="/app.js">                    → ALLOWED ('self')
+   - <script>alert('xss')</script>             → BLOCKED (no 'unsafe-inline')
+   - <img src="https://tracker.com/pixel.gif"> → BLOCKED (if img-src: 'self')
 
-4. Violation wird in Browser Console geloggt
-   (optional: an report-uri gesendet)
+4. Violation is logged in browser console
+   (optionally: sent to report-uri)

+**The three CSP strategies (from weak to strong):**
 
-| Strategie | Sicherheit | Praktikabilität | Beschreibung |
+| Strategy | Security | Practicality | Description |
 |-----------|-----------|-----------------|-------------|
-| **Allowlist-basiert** | Mittel | Hoch | Domains explizit erlauben (`script-src 'self' cdn.example.com`) |
-| **Nonce-basiert** | Hoch | Mittel | Zufälliger Token pro Request (`script-src 'nonce-abc123'`) |
-| **Hash-basiert** | Hoch | Niedrig | SHA-256 Hash jedes Scripts (`script-src 'sha256-...'`) |
+| **Allowlist-based** | Medium | High | Explicitly allow domains (`script-src 'self' cdn.example.com`) |
+| **Nonce-based** | High | Medium | Random token per request (`script-src 'nonce-abc123'`) |
+| **Hash-based** | High | Low | SHA-256 hash of each script (`script-src 'sha256-...'`) |
 
-**Nonce-basiert ist der empfohlene Ansatz** – Google nennt es ["strict CSP"](https://web.dev/articles/strict-csp). Es funktioniert so:
+**Nonce-based is the recommended approach** – Google calls it ["strict CSP"](https://web.dev/articles/strict-csp). It works like this:
 
-1. Server generiert pro Request eine zufällige Nonce (z.B. `a1b2c3d4`)
-2. Server setzt den Header: `script-src 'nonce-a1b2c3d4' 'strict-dynamic'`
-3. Server fügt die Nonce in jedes `<script>` Tag ein: `<script nonce="a1b2c3d4">`
-4. Browser führt nur Scripts mit korrekter Nonce aus
-5. `'strict-dynamic'` erlaubt, dass diese Scripts weitere Scripts dynamisch laden dürfen
+1. Server generates a random nonce per request (e.g. `a1b2c3d4`)
+2. Server sets the header: `script-src 'nonce-a1b2c3d4' 'strict-dynamic'`
+3. Server adds the nonce to every `<script>` tag: `<script nonce="a1b2c3d4">`
+4. Browser only executes scripts with the correct nonce
+5. `'strict-dynamic'` allows these scripts to dynamically load further scripts
 
-**`'strict-dynamic'` erklärt:** Wenn ein vertrauenswürdiges Script (mit Nonce) ein weiteres Script per `document.createElement('script')` lädt, wird das Kind-Script automatisch als vertrauenswürdig eingestuft. Ohne `'strict-dynamic'` würden diese dynamisch geladenen Scripts blockiert – was die meisten Frameworks (React, Vue, etc.) kaputt machen würde.
+**`'strict-dynamic'` explained:** When a trusted script (with nonce) loads another script via `document.createElement('script')`, the child script is automatically trusted. Without `'strict-dynamic'`, these dynamically loaded scripts would be blocked — which would break most frameworks (React, Vue, etc.).
 
-**Warum `'unsafe-inline'` vermeiden?** `'unsafe-inline'` erlaubt JEDES Inline-Script. Ein Angreifer der HTML injecten kann (`<script>steal()</script>`), hat damit freie Bahn. Nonces lösen das: Nur Scripts mit der korrekten (nicht erratbaren) Nonce werden ausgeführt.
+**Why avoid `'unsafe-inline'`?** `'unsafe-inline'` allows EVERY inline script. An attacker who can inject HTML (`<script>steal()</script>`) has free reign. Nonces solve this: only scripts with the correct (unguessable) nonce are executed.
 
-**Das `'unsafe-inline'` Dilemma bei Styles:** Viele Frameworks (Tailwind, styled-components, Material UI) setzen Inline-Styles. Hier ist `'unsafe-inline'` für `style-src` oft ein akzeptabler Kompromiss – Inline-Styles sind deutlich weniger gefährlich als Inline-Scripts (kein Code-Execution).
+**The `'unsafe-inline'` dilemma for styles:** Many frameworks (Tailwind, styled-components, Material UI) set inline styles. Here `'unsafe-inline'` for `style-src` is often an acceptable compromise — inline styles are significantly less dangerous than inline scripts (no code execution).

-### DOM XSS – Moderne Schutzschicht
+### DOM XSS – Modern Protection Layer
 
-Klassisches Output-Encoding reicht für DOM-basiertes XSS nicht aus, wenn JavaScript-Code direkt in DOM-Sinks (`innerHTML`, `document.write`, `src`) schreibt. Moderne Abwehr in zwei Schichten:
+Classic output encoding is not enough for DOM-based XSS when JavaScript code writes directly to DOM sinks (`innerHTML`, `document.write`, `src`). Modern defense in two layers:
 
-**Schicht 1: Trusted Types (Browser-Enforcement)**
+**Layer 1: Trusted Types (browser enforcement)**
 
 ```text
 Content-Security-Policy: require-trusted-types-for 'script'
 ```
 
-Erzwingt, dass alle Zuweisungen an DOM-Sinks durch eine deklarierte Policy laufen. Rohe Strings werden vom Browser blockiert. Google nennt dies die einzige Maßnahme die DOM XSS strukturell eliminiert.
+Enforces that all assignments to DOM sinks go through a declared policy. Raw strings are blocked by the browser. Google calls this the only measure that structurally eliminates DOM XSS.
 
-**Schicht 2: DOMPurify (Sanitizer)**
+**Layer 2: DOMPurify (sanitizer)**
 
-Wenn HTML-Injektion unvermeidbar ist (z.B. Rich Text), `DOMPurify.sanitize()` vor jeder `innerHTML`-Zuweisung:
+When HTML injection is unavoidable (e.g. rich text), `DOMPurify.sanitize()` before every `innerHTML` assignment:
 
 ```javascript
-// Unsicher:
+// Unsafe:
 element.innerHTML = userContent;
 
-// Sicher:
+// Safe:
 element.innerHTML = DOMPurify.sanitize(userContent);
 
-// Mit Trusted Types kombiniert:
+// Combined with Trusted Types:
 const policy = trustedTypes.createPolicy('default', {
     createHTML: input => DOMPurify.sanitize(input)
 });
 element.innerHTML = policy.createHTML(userContent);
 ```
 
-**Alternatives natives API (Browser-Support ab 2024/2025):** `element.setHTML()` — sanitiert automatisch, kein externes Library nötig. Noch nicht universal verfügbar.
+**Alternative native API (browser support from 2024/2025):** `element.setHTML()` — sanitizes automatically, no external library needed. Not yet universally available.
 
-**Faustregel:**
-- `.textContent` statt `.innerHTML` wo kein HTML nötig ist
-- `DOMPurify` für jeden Fall wo HTML-Injection nötig ist
-- Trusted Types als CSP-Directive für strukturelle Durchsetzung
+**Rule of thumb:**
+- `.textContent` instead of `.innerHTML` where no HTML is needed
+- `DOMPurify` for every case where HTML injection is needed
+- Trusted Types as CSP directive for structural enforcement

-| Caching | HTTP-Caching einfach | Custom | Apollo Cache, komplexer |
-| Mehrere Clients | Gut (Standard) | Nur TypeScript | Gut (jede Sprache) |
-| Best für | Public APIs, Multi-Client | Full-Stack TypeScript | Komplexe Datenmodelle |

-### Migrations-Regeln
+### Migration Rules
 
-| Regel | Warum |
+| Rule | Why |
 |-------|-------|
-| **Immer vorwärts** | Rollback-Migrations sind fehleranfällig. Lieber neue Migration die den Fehler korrigiert. |
-| **Idempotent** | `IF NOT EXISTS`, `IF EXISTS` verwenden |
-| **Kleine Schritte** | Eine Änderung pro Migration |
-| **Daten-Migration separat** | Schema-Änderung ≠ Daten-Migration |
-| **Testen in Staging** | Nie ungetestet auf Produktion |
+| **Always forward** | Rollback migrations are error-prone. Better a new migration that corrects the error. |
+| **Idempotent** | Use `IF NOT EXISTS`, `IF EXISTS` |
+| **Small steps** | One change per migration |
+| **Separate data migrations** | Schema change ≠ data migration |
+| **Test in staging** | Never untested on production |
 
 ### ORM vs. Raw SQL vs. Query Builder
 
-| Ansatz | Vorteil | Nachteil |
+| Approach | Advantage | Disadvantage |
 |--------|---------|----------|
-| **ORM** (Prisma, SQLAlchemy, Django ORM) | Produktiv, Type-Safe, Migrations | Abstraktion kann problematisch werden, N+1 Queries |
-| **Query Builder** (Drizzle, Knex, SQLAlchemy Core) | SQL-nah, Type-Safe, flexibel | Mehr Schreibarbeit als ORM |
-| **Raw SQL** | Volle Kontrolle, optimale Performance | Kein Type-Safety, SQL-Injection-Risiko |
+| **ORM** (Prisma, SQLAlchemy, Django ORM) | Productive, type-safe, migrations | Abstraction can be problematic, N+1 queries |
+| **Query builder** (Drizzle, Knex, SQLAlchemy Core) | Close to SQL, type-safe, flexible | More boilerplate than ORM |
+| **Raw SQL** | Full control, optimal performance | No type safety, SQL injection risk |
 
-**Empfehlung 2026:** Query Builder (Drizzle, SQLAlchemy Core) als Sweet Spot. ORM für schnelle Prototypen. Raw SQL nur für komplexe Queries.
+**Recommendation 2026:** Query builder (Drizzle, SQLAlchemy Core) as sweet spot. ORM for rapid prototypes. Raw SQL only for complex queries.
 
 ### Connection Pooling
 
-**Warum:** Datenbankverbindungen sind teuer (TCP Handshake, Auth, TLS). Pooling hält Verbindungen offen und wiederverwendet sie.
+**Why:** Database connections are expensive (TCP handshake, auth, TLS). Pooling keeps connections open and reuses them.
 
-| Umgebung | Tool |
+| Environment | Tool |
 |----------|------|
-| Serverful (Node/Python langlebig) | Built-in Pool (Prisma, SQLAlchemy) |
-| Serverless (Lambda, Edge) | **PgBouncer** (extern), **Neon Pooler**, **Prisma Accelerate** |
-| Docker | PgBouncer als Sidecar-Container |
+| Serverful (Node/Python long-lived) | Built-in pool (Prisma, SQLAlchemy) |
+| Serverless (Lambda, Edge) | **PgBouncer** (external), **Neon Pooler**, **Prisma Accelerate** |

-| **Write-Through** | Konsistenz wichtig | Schreibe in Cache UND DB gleichzeitig |
-| **Write-Behind** | Performance wichtig | Schreibe in Cache, DB asynchron |
-| **TTL-based** | Einfachster Ansatz | Daten ablaufen nach X Sekunden |

 ### HTTP Caching Headers
 
-| Header | Zweck | Beispiel |
+| Header | Purpose | Example |
 |--------|-------|---------|
-| `Cache-Control` | Hauptsteuerung | `public, max-age=3600, stale-while-revalidate=60` |
-| `ETag` | Versionierung | `"abc123"` – Server prüft ob sich Ressource geändert hat |
-| `Last-Modified` | Zeitbasiert | Browser sendet `If-Modified-Since` |
-| `Vary` | Cache-Key Variation | `Vary: Accept-Encoding` |
+| `Cache-Control` | Main control | `public, max-age=3600, stale-while-revalidate=60` |
+| `ETag` | Versioning | `"abc123"` – server checks if resource has changed |
+| `Last-Modified` | Time-based | Browser sends `If-Modified-Since` |
+| `Vary` | Cache key variation | `Vary: Accept-Encoding` |
 
-**Praxis-Empfehlung:**
+**Practical recommendation:**
 
 ```text
-# Statische Assets (JS/CSS/Bilder mit Hash im Dateinamen)
+# Static assets (JS/CSS/images with hash in filename)
 Cache-Control: public, max-age=31536000, immutable
 
-# API-Responses (dynamisch, aber cachebar)
+# API responses (dynamic, but cacheable)

+### Flag Hygiene (prevents flag debt)
 
-- **Maximale Lebensdauer:** Release Flags max. 1 Sprint aktiv halten
-- **Ticket bei Erstellung:** Jeder Flag bekommt ein "Cleanup"-Ticket mit Deadline
-- **Nie für Dauerkonfiguration:** Permanente Konfiguration gehört in Env Vars, nicht in Flags
-- **Testen beider Pfade:** CI muss beide Zustände (Flag an + aus) testen
+- **Maximum lifetime:** Release flags active for max. 1 sprint
+- **Ticket on creation:** Every flag gets a "cleanup" ticket with deadline
+- **Never for permanent config:** Permanent configuration belongs in env vars, not flags
+- **Test both paths:** CI must test both states (flag on + off)
 
 ### Anti-Patterns
 
-- Flag ohne Cleanup-Datum → wird nie entfernt (Flag-Schulden)
-- Geschachtelte Flags (`if (flagA && flagB && !flagC)`) → unmöglich zu verstehen
-- Flags für sicherheitskritische Entscheidungen (Auth, Zahlungen) → zu risikoreich
-- Flag-State in DB (nicht in Flag-Service) → Konsistenzprobleme bei Multi-Instance
+- Flag without cleanup date → never gets removed (flag debt)
+- Nested flags (`if (flagA && flagB && !flagC)`) → impossible to understand
+- Flags for security-critical decisions (auth, payments) → too risky
+- Flag state in DB (not in flag service) → consistency issues with multi-instance

 |-------|-----|----------|------|
-| **Logs** | Diskrete Events (Textzeilen) | "User login failed for user@example.com" | Pino, structlog |
-| **Metrics** | Numerische Messwerte über Zeit | Request-Rate: 150/s, Error-Rate: 0.3%, Latency p95: 240ms | Prometheus, StatsD |
-| **Traces** | Request-Pfad durch mehrere Services | Request → API Gateway → Auth Service → DB → Response (320ms) | Jaeger, Zipkin |
+| **Logs** | Discrete events (text lines) | "User login failed for user@example.com" | Pino, structlog |

+| **Traces** | Request path through multiple services | Request → API gateway → Auth service → DB → Response (320ms) | Jaeger, Zipkin |
 
-**Logs alleine reichen nicht.** Logs sagen _was_ passiert ist. Metrics sagen _wie oft_ und _wie schnell_. Traces sagen _wo genau_ im System ein Problem liegt.
+**Logs alone are not enough.** Logs say _what_ happened. Metrics say _how often_ and _how fast_. Traces say _where exactly_ in the system a problem lies.

+### OpenTelemetry (OTel) – The Standard
 
-OpenTelemetry ist der herstellerunabhängige Standard für Observability-Daten. Statt für jeden Anbieter (Datadog, Sentry, Grafana) eine eigene Integration zu bauen, instrumentiert man einmal mit OTel und schickt die Daten an ein beliebiges Backend.
+OpenTelemetry is the vendor-independent standard for observability data. Instead of building a separate integration for every provider (Datadog, Sentry, Grafana), you instrument once with OTel and send data to any backend.
 
 ```text

-**Warum OTel statt Vendor-SDK?**
-- Vendor Lock-in vermeiden: Backend wechseln ohne Code-Änderung
-- Ein SDK für Logs + Metrics + Traces
-- Breite Community, viele Auto-Instrumentierungen
+**Why OTel instead of vendor SDK?**
+- Avoid vendor lock-in: switch backend without code changes
+- One SDK for logs + metrics + traces
+- Large community, many auto-instrumentations

 ## 3. Clean Architecture / Hexagonal Architecture
 
-### Grundidee
+### Core Idea
 
-Die Business-Logik (Domain) ist der Kern und hat **keine Abhängigkeit** zu Frameworks, Datenbanken oder externen Services. Alles Externe ist austauschbar.
+The business logic (domain) is the core and has **no dependency** on frameworks, databases, or external services. Everything external is replaceable.

+## 11. Environment Strategies
 
 ### Minimum: Dev + Production (2-Tier)
 
-Für Solo-Projekte und kleine Teams reicht oft ein 2-Tier-Setup:
+For solo projects and small teams, a 2-tier setup is often enough:
 
-| Aspekt | Development | Production |
+| Aspect | Development | Production |
 |--------|------------|------------|
-| **Datenbank** | Lokal (Docker) oder SQLite | Echte Daten |
-| **External APIs** | Mocks / Sandbox | Live |
-| **Debug Mode** | An | **Aus** |
-| **Logging Level** | debug | info/warn |
-| **SSL** | Optional (localhost) | Ja |
-| **Secrets** | `.env` lokal | CI/CD Secrets / Vault |
-| **Error Detail** | Stack Traces | Generische Meldung |
-
-**Das reicht wenn:**
-- Solo-Entwickler oder kleines Team (1-3 Personen)
-- Kein Kunden-facing SLA (interne Tools, Side Projects)
-- Deployments sind schnell revertbar (Docker, Vercel, etc.)
-- Gute Test-Coverage als Sicherheitsnetz
-
-**Empfohlene Absicherung ohne Staging:**
-- CI Pipeline mit Tests + Linting (ersetzt manuelles Staging-Testing)
-- Docker-Image lokal testen bevor man deployed (`docker compose up` mit Prod-Config)
-- Feature Flags für riskante Changes (schrittweise aktivieren)
-- Health Checks + Rollback-Strategie im Deployment
+| **Database** | Local (Docker) or SQLite | Real data |
+| **External APIs** | Mocks / sandbox | Live |
+| **Debug mode** | On | **Off** |
+| **Logging level** | debug | info/warn |
+| **SSL** | Optional (localhost) | Yes |
+| **Secrets** | `.env` local | CI/CD secrets / Vault |
+| **Error detail** | Stack traces | Generic message |
+
+**This is enough when:**
+- Solo developer or small team (1-3 people)
+- No customer-facing SLA (internal tools, side projects)
+- Deployments are quickly revertable (Docker, Vercel, etc.)
+- Good test coverage as safety net
+
+**Recommended protection without staging:**
+- CI pipeline with tests + linting (replaces manual staging testing)
+- Test Docker image locally before deploying (`docker compose up` with prod config)
+- Feature flags for risky changes (gradual activation)
+- Health checks + rollback strategy in deployment
 
 ### Level Up: Dev + Staging + Production (3-Tier)
 
-Staging wird sinnvoll wenn:
-- **Mehrere Entwickler** gleichzeitig deployen
-- **Externe Abhängigkeiten** (Payment APIs, Third-Party Webhooks) getestet werden müssen
-- **Datenbank-Migrationen** komplex sind und vor Prod validiert werden sollten
-- **Kunden/Stakeholder** vor Release testen wollen (UAT)
-- **Compliance-Anforderungen** eine Pre-Production-Validierung verlangen
+Staging becomes useful when:
+- **Multiple developers** deploy simultaneously
+- **External dependencies** (payment APIs, third-party webhooks) need to be tested
+- **Database migrations** are complex and should be validated before prod
+- **Customers/stakeholders** want to test before release (UAT)
+- **Compliance requirements** demand pre-production validation

-| 8 | **Concurrency** | Skalierung über Prozesse | Mehrere Container, nicht Threads |
-| 9 | **Disposability** | Schnell starten, graceful stoppen | SIGTERM Handling, Health Checks |
-| 10 | **Dev/Prod Parity** | Environments angleichen | Docker macht Dev ≈ Prod |
-| 11 | **Logs** | Als Event-Streams | Stdout/Stderr, nicht in Dateien |

-### Mocking-Strategie
+### Mocking Strategy
 
-| Regel | Erklärung |
+| Rule | Explanation |
 |-------|-----------|
-| **Mocke an Systemgrenzen** | HTTP-Calls, DB, Filesystem, externe APIs |
-| **Mocke nicht die eigene Logik** | Interne Funktionen nicht mocken → sonst testet man nichts |
-| **Bevorzuge Fakes über Mocks** | In-Memory-DB statt DB-Mock, MSW statt fetch-Mock |
-| **Mock so wenig wie möglich** | Je mehr Mocks, desto weniger Aussagekraft |
+| **Mock at system boundaries** | HTTP calls, DB, filesystem, external APIs |
+| **Don't mock your own logic** | Internal functions not mocked → otherwise you test nothing |
+| **Prefer fakes over mocks** | In-memory DB instead of DB mock, MSW instead of fetch mock |
+| **Mock as little as possible** | More mocks = less meaningful |

 |--------|----------|-----------|
-| **Line Coverage** | 70-80% | Mehr ist nice-to-have, nicht Pflicht |
-| **Branch Coverage** | 60-70% | Wichtiger als Line Coverage |
-| **Kritische Pfade** | ~100% | Auth, Payment, Datenverlust-Szenarien |
+| **Line coverage** | 70-80% | More is nice-to-have, not required |
+| **Branch coverage** | 60-70% | More important than line coverage |
+| **Critical paths** | ~100% | Auth, payment, data loss scenarios |
 
-**100% Coverage ist kein Ziel.** Es führt zu Test-Bloat und falscher Sicherheit. Besser: kritische Pfade gut testen, Triviales weglassen.

+| Approach | When useful |
 |--------|--------------|
-| **Test-First (TDD)** | Bug-Fixing (reproduziere Bug als Test, dann fixen), komplexe Logik |
-| **Test-After** | UI-Code, Prototypen, explorative Phase |
-| **Test-During** | Guter Kompromiss: Feature + Test in derselben PR |
+| **Test-First (TDD)** | Bug fixing (reproduce bug as test, then fix), complex logic |
+| **Test-After** | UI code, prototypes, exploratory phase |
+| **Test-During** | Good compromise: feature + test in the same PR |
 
-**Pragmatischer Ansatz:** Test-During als Default. TDD für Bugs und komplexe Logik. Bei Prototypen: gar nicht, aber nachholen vor Production.

-#### Was beim Review prüfen
+#### What to Check in Review
 
-| Kategorie | Worauf achten |
+| Category | What to look for |
 |-----------|--------------|
-| **Korrektheit** | Tut der Code was er soll? Edge Cases? Off-by-one? |
-| **Design** | Passt es zur bestehenden Architektur? Zu komplex? Zu clever? |
-| **Lesbarkeit** | Verständlich ohne Erklärung? Gute Benennung? |
-| **Sicherheit** | Input-Validierung? Secrets? SQL Injection? XSS? |
-| **Performance** | N+1 Queries? Unnötige Loops? Große Payloads? |
-| **Error Handling** | Was passiert bei Fehlern? Werden sie verschluckt? |
-| **Tests** | Sind die richtigen Szenarien getestet? |
-| **Breaking Changes** | API-Änderungen die andere Clients betreffen? |
-
-#### Review-Etikette
-
-| Regel | Warum |
+| **Correctness** | Does the code do what it should? Edge cases? Off-by-one? |
+| **Design** | Does it fit the existing architecture? Too complex? Too clever? |
+| **Readability** | Understandable without explanation? Good naming? |
+| **Security** | Input validation? Secrets? SQL injection? XSS? |
+| **Performance** | N+1 queries? Unnecessary loops? Large payloads? |
+| **Error handling** | What happens on errors? Are they swallowed? |
+| **Tests** | Are the right scenarios tested? |
+| **Breaking changes** | API changes affecting other clients? |
+
+#### Review Etiquette
+
+| Rule | Why |
 |-------|-------|
-| **Fragen statt Befehle** | "Wäre X hier besser?" statt "Mach X" |
-| **Begründen** | "Lieber Y weil Z" statt nur "Mach Y" |
-| **Nitpicks kennzeichnen** | `nit:` Prefix für Kleinigkeiten (optional, nicht blockierend) |
-| **Positives erwähnen** | Gute Lösungen loben → fördert Motivation |
-| **Blocker klar markieren** | Muss gefixt werden vs. Vorschlag/Idee |
-| **Zeitnah reviewen** | Innerhalb von 24h, sonst wird es zum Bottleneck |
+| **Ask questions instead of commands** | "Would X be better here?" instead of "Do X" |
+| **Give reasons** | "Prefer Y because Z" instead of just "Do Y" |
+| **Mark nitpicks** | `nit:` prefix for small things (optional, not blocking) |
+| **Mention positives** | Praise good solutions → encourages motivation |
+| **Clearly mark blockers** | Must be fixed vs. suggestion/idea |
+| **Review promptly** | Within 24 hours, otherwise becomes a bottleneck |
