refactor: complete bootstrap of ARNES agent harness framework

- Add complete agent harness structure with 8 roles (leader, triager, architect, implementer, reviewer, security, qa, documenter)
- Implement strict workflow with 9 stages and mandatory gates
- Add comprehensive verification script and runtime status tracking
- Create artifact-based evidence system with contracts and schemas
- Add agent policy matrix with permissions and anti-cheat rules
- Include test suite (44 tests passing) and CI-ready structure
- Add documentation: README, HOWTO, CHECKPOINTS, templates
- Configure model routing policies and token-aware task assignment
- Add BDD/SDD specification guides and feature templates
- Include starter pack for quick project onboarding

All verification checks pass. Framework ready for production use.

+# Cómo crear una Feature con SDD y BDD
+
+Guía paso a paso para crear una feature usando System Design Document y Behavior Driven Development.
+
+---
+
+## 📋 Flujo general
+
+```
+1. Analizar la feature del backlog
+       ↓
+2. Crear SPEC/BBD (architect)
+       ↓
+3. Crear/actualizar SDD (architect)
+       ↓
+4. Generar código + tests (implementer)
+       ↓
+5. Review, Security, QA gates
+       ↓
+6. Cerrar feature
+```
+
+---
+
+## Paso 1: Analizar del Backlog
+
+Ejemplo: F-002 "Gestión de Perfil de Usuario"
+
+```json
+{
+  "id": "F-002",
+  "title": "Gestión de Perfil de Usuario",
+  "description": "El usuario puede ver y editar su perfil (nombre, avatar, preferencias).",
+  "acceptance": [
+    "Usuario puede ver su perfil",
+    "Usuario puede editar nombre y avatar",
+    "Usuario puede cambiar preferencias de idioma",
+    "Validación de datos en todos los campos"
+  ]
+}
+```
+
+---
+
+## Paso 2: Crear SDD (System Design Document)
+
+### 2.1 Crear componente
+
+Archivo: `spec/sdd/components/user-profile-service.md`
+
+```markdown
+# Component: UserProfileService
+
+## Responsabilidad
+Gestionar el perfil de usuario: consulta, actualización de datos básicos y preferencias.
+
+## Tipo
+- [x] Microservicio
+
+## Interfaces
+
+### API REST
+
+```
+GET /api/v1/users/{user_id}/profile
+Output: { "id", "name", "avatar_url", "language", "created_at" }
+
+PUT /api/v1/users/{user_id}/profile
+Input:  { "name": string, "avatar_url": string, "language": string }
+Output: { "id", "name", "avatar_url", "language", "updated_at" }
+```
+
+## Validaciones
+- name: 2-50 caracteres, sin caracteres especiales
+- avatar_url: URL válida (http/https)
+- language: enum ['en', 'es', 'fr', 'de']
+```
+
+### 2.2 Crear ADR (si hay decisión técnica)
+
+Archivo: `spec/sdd/decisions/002-almacenamiento-avatar.md`
+
+---
+
+## Paso 3: Crear BDD (Behavior Driven Development)
+
+### 3.1 Crear archivo .feature
+
+Archivo: `spec/bdd/features/profile/user-profile.feature`
+
+```gherkin
+@F-002 @profile
+Feature: Gestión de Perfil de Usuario
+
+  Como usuario autenticado
+  Quiero gestionar mi perfil
+  Para mantener mis datos actualizados
+
+  @smoke
+  Scenario: Ver perfil de usuario
+    Given un usuario autenticado con ID "user-123"
+    When el usuario solicita ver su perfil
+    Then el sistema retorna datos del perfil
+    And incluye nombre, avatar y preferencias
+
+  Scenario: Editar nombre del perfil
+    Given un usuario autenticado con ID "user-123"
+    And el perfil tiene nombre "Juan"
+    When el usuario actualiza su nombre a "Pedro"
+    Then el perfil muestra nombre "Pedro"
+    And la fecha de actualización se registra
+
+  @negative
+  Scenario: Editar nombre con caracteres inválidos
+    Given un usuario autenticado
+    When intenta cambiar nombre a "Juan@123!"
+    Then el sistema muestra error "Nombre inválido"
+    And el nombre permanece sin cambios
+
+  Scenario: Cambiar idioma a español
+    Given un usuario con idioma "en"
+    When cambia idioma a "es"
+    Then toda la interfaz se muestra en español
+    And el preference se guarda correctamente
+```
+
+### 3.2 Escribir Step Definitions
+
+Archivo: `features/steps/profile_steps.py`
+
+```python
+from behave import given, when, then
+
+@given('un usuario autenticado con ID "{user_id}"')
+def step_user_authenticated(context, user_id):
+    context.user_id = user_id
+    context.auth_token = f"token_{user_id}"
+
+@when('el usuario solicita ver su perfil')
+def step_get_profile(context):
+    profile_service = ProfileService()
+    context.profile = profile_service.get_profile(context.user_id)
+
+@then('el sistema retorna datos del perfil')
+def step_return_profile(context):
+    assert context.profile is not None
+    assert "name" in context.profile
+
+# ... más steps
+```
+
+---
+
+## Paso 4: Ejecutar el pipeline ARNES
+
+### Stage: design (architect)
+- ✅ Crea SDD component
+- ✅ Crea BDD feature
+- ✅ Produces `work/artifacts/F-002/architect.md`
+
+### Stage: build (implementer)
+- Implementa `UserProfileService`
+- Escribe step definitions
+- Ejecuta `behave` para verificar
+
+### Stage: review_gate (reviewer)
+- Verifica código coincide con SDD
+- Verifica BDD coverage
+
+### Stage: security_gate (security)
+- Check secrets, dependencies
+- SAST scan
+
+### Stage: qa_gate (qa)
+- Ejecuta BDD scenarios
+- Verifica trazabilidad
+
+### Stage: close (leader)
+- Verifica todos los gates en verde
+- Produce `leader-close.json`

-# HOWTO — Cómo usar ARNES Framework
+# HOWTO (breve) — iniciar ARNES en proyecto nuevo o ya empezado
 
-Guía rápida para arrancar proyectos nuevos usando este framework.
+## 1) Proyecto nuevo (greenfield)
-
----
-
-## Fórmula base (siempre igual)
-
-1. **Crear repo nuevo**
-2. **Copiar ARNES Framework dentro del repo**
-3. **Configurar spec + backlog**
-4. **Ejecutar verificación**
-5. **Empezar implementación por features (una a la vez)**
-
----
-
-## 1) Crear repo
 
 ```bash
-mkdir mi-proyecto
+mkdir mi-proyecto && cd mi-proyecto
-cd mi-proyecto
 git init
-```
+# copiar contenido de arnes-fork aquí
-
+./scripts/start.sh
----
-
-## 2) Copiar framework
-
-Desde tu copia local de ARNES:
-
-```bash
-cp -R /ruta/a/arnes/* .
-cp -R /ruta/a/arnes/.[!.]* . 2>/dev/null || true
-```
-
-> Si usas plantilla remota, clónala y copia su contenido al repo nuevo.
-
----
-
-## 3) Personalizar proyecto
-
-Edita mínimo:
-
-- `README.md` (contexto del proyecto)
-- `spec/product.md` (qué construir)
-- `spec/tech.md` (stack y límites técnicos)
-- `spec/acceptance.md` (criterios de aceptación)
-- `backlog/features.json` (features iniciales en `pending`)
-- `harness/agents.matrix.yml` (roles/permisos)
-- `harness/workflow.stages.yml` (flujo y gates)
-
----
-
-## 4) Elegir plataforma (pi.dev u opencode)
-
-Usa el adaptador correspondiente:
-
-- `platforms/pi/`
-- `platforms/opencode/`
-
-El núcleo del framework no cambia; solo cambian prompts/hooks/permisos de plataforma.
-
----
-
-## 5) Inicializar estado de trabajo
-
-Verifica que existan y estén limpios:
-
-- `work/current.md`
-- `work/history.md`
-- `work/artifacts/`
-
-Pon solo **1 feature activa** (`in_progress`) como máximo.
-
----
-
-## 6) Ejecutar verificación inicial
-
-```bash
 ./scripts/verify.sh
+python3 scripts/agent_status.py show
 ```
 
-Si falla, **no empezar implementación** hasta dejar todo en verde.
+Después:
+- Edita `backlog/features.json` (`project`, `description`).
+- Crea tu primera feature `pending` (puedes usar `starter-pack/backlog.features.bootstrap.json`).
+- Empieza el ciclo SDD (una feature a la vez).
 
 ---
 
-## 7) Ciclo operativo por feature
+## 2) Proyecto ya empezado (brownfield)
 
-Orden obligatorio:
+Copia al repo existente solo el core ARNES:
+- `harness/`
+- `spec/`
+- `backlog/`
+- `work/`
+- `scripts/`
+- `platforms/`
+- `AGENTS.md`, `CHECKPOINTS.md`
 
-1. `leader` orquesta
+Luego ejecuta:
-2. `architect` define/ajusta diseño
-3. `implementer` implementa + tests
-4. `reviewer` gate técnico
-5. `security` gate seguridad
-6. `qa` gate funcional
-7. `leader` cierra si todo está aprobado
 
-Reglas clave:
+```bash
-- una feature a la vez
+./scripts/start.sh
-- evidencia en disco (`work/artifacts/<feature>/...`)
+./scripts/verify.sh
-- nadie marca `done` si falta un gate
+python3 scripts/agent_status.py show
+```
+
+Y añade checks del dominio en:
+- `scripts/verify.local.sh` (opcional)
 
 ---
 
-## 8) Cierre de feature
+Crear ticket nuevo (leader/triager, EN caveman):
+```bash
+python3 scripts/new_ticket.py
+```
 
-Antes de pasar a `done`:
+Modelo por tarea:
+- Config base en `harness/models.profiles.yml`
+- Reglas en `harness/policies/model-routing.md`
 
-- `verify.sh` en verde
+## Reglas operativas mínimas
-- review aprobado
+- Máximo una feature en `in_progress`.
-- security aprobado
+- `done` requiere gates `review/security/qa` aprobados.
-- qa aprobado
+- Evidencia siempre en `work/artifacts/<feature_id>/`.
-- resumen en `work/history.md`
+- Si `verify.sh` falla, no se cierra la feature.
-
----
-
-## 9) Manejo de pérdida de contexto (memoria)
-
-Si una sesión se corta:
-
-1. leer `work/current.md`
-2. revisar `backlog/features.json`
-3. abrir artefactos de la feature activa
-4. ejecutar `./scripts/verify.sh`
-5. continuar desde “Próximo paso”
-
----
-
-## 10) Checklist rápido de arranque
-
-- [ ] Repo creado
-- [ ] Framework copiado
-- [ ] Specs escritas
-- [ ] Backlog definido
-- [ ] Matriz de agentes configurada
-- [ ] Workflow de stages configurado
-- [ ] Verificación inicial OK
-- [ ] Primera feature en `pending`
-
----
-
-## Comando mental (resumen)
-
-**Crear repo → copiar framework → definir spec/backlog → verificar → ejecutar pipeline de 6 agentes con gates obligatorios.**

+# Manual de uso — Skeleton 2.0.4 (para ARNES template)
+
+> Fuente revisada: `https://github.com/getskeleton/Skeleton` (v2.0.4, 2014).
+
+## 1) Qué es y cuándo usarlo
+Skeleton es un boilerplate CSS ligero (no framework UI completo). Ideal para:
+- paneles internos
+- CRUDs
+- prototipos rápidos
+- apps server-rendered (Flask + Jinja)
+
+No ideal para:
+- diseño de componentes complejos
+- design systems avanzados
+- apps con alta complejidad visual
+
+## 2) Archivos base
+En este template se incluyen en:
+- `defaults/flask-skeleton/static/css/normalize.css`
+- `defaults/flask-skeleton/static/css/skeleton.css`
+- `defaults/flask-skeleton/static/images/favicon.png`
+
+Uso recomendado en HTML:
+```html
+<link rel="stylesheet" href="/static/css/normalize.css">
+<link rel="stylesheet" href="/static/css/skeleton.css">
+```
+
+## 3) Grid (12 columnas)
+Estructura:
+```html
+<div class="container">
+  <div class="row">
+    <div class="six columns">...</div>
+    <div class="six columns">...</div>
+  </div>
+</div>
+```
+
+Clases comunes:
+- `one` ... `twelve columns`
+- `one-half column`
+- `one-third column`
+- `two-thirds column`
+
+Offsets:
+- `offset-by-one ... offset-by-eleven`
+
+Breakpoints relevantes:
+- `min-width: 400px`
+- `min-width: 550px` (aquí se activa grid multi-columna)
+- `750px`, `1000px`, `1200px`
+
+## 4) Utilidades clave
+- `u-full-width` → ancho 100%
+- `u-max-full-width` → max-width 100%
+- `u-pull-right`, `u-pull-left`
+- `u-cf` (clear float)
+
+## 5) Formularios y botones
+Inputs/select/textarea ya traen estilo base.
+Patrones recomendados:
+- siempre usar `u-full-width` en formularios de app
+- usar `.button` y `.button.button-primary`
+- mantener labels visibles (`label` + `for`)
+
+## 6) Tablas
+Skeleton trae estilo mínimo. Para tablas largas:
+- envolver en `.table-responsive` propia del proyecto
+- controlar overflow horizontal en móviles
+
+## 7) Limitaciones conocidas (por antigüedad)
+- Sistema basado en **floats** (no flex/grid nativo)
+- Tipografía por defecto antigua (Raleway de Google Fonts vía URL legacy)
+- No incluye componentes modernos (modal, tabs, toast, etc.)
+- No incluye tokens de diseño ni theming avanzado
+
+## 8) Mejoras recomendadas en proyectos nuevos
+Mantener Skeleton como base, pero añadir capa moderna propia:
+
+1. **Layout helper CSS local**
+   - utilidades flex (`.d-flex`, `.justify-between`, etc.)
+   - spacing consistente (`.mb-1`, `.mb-2`, ...)
+
+2. **Responsive wrappers**
+   - `.table-responsive`
+   - patrones mobile-first para filtros/toolbar
+
+3. **Componentes mínimos reutilizables**
+   - modal base
+   - badges
+   - pagination bar
+   - alertas/confirmaciones
+
+4. **Accesibilidad**
+   - foco visible
+   - contraste de colores
+   - labels/aria en acciones icon-only
+
+5. **No tocar upstream directamente**
+   - dejar `skeleton.css` y `normalize.css` sin modificar
+   - personalización en `custom.css` del proyecto
+
+## 9) Regla de mantenimiento para ARNES
+- Skeleton se trata como dependencia estática base.
+- Cualquier override va en CSS del proyecto.
+- Si un proyecto requiere UI compleja, considerar migración progresiva a capa de componentes propia.

+# Policy: Language and style
+
+## Internal language
+- Internal artifacts, tickets, and leader orders must be in **English**.
+- User chat can be in any language.
+
+## Style mode: Caveman English
+- Short words.
+- Short lines.
+- One idea per line.
+- No fluff.
+- No long intros.
+- Prefer bullets.
+
+## Ticket writing rules
+- Title: 4–10 words.
+- Acceptance: 3–6 bullets max.
+- Keep scope explicit (in/out).
+- Use active verbs: Fix, Add, Move, Remove, Validate.
+
+## Runtime action rules
+- `agent_status.action` should be concise (<= 60 chars).

+# Policy: Model routing
+
+Use model by task complexity, not by habit.
+
+## Core rule
+- Start small.
+- Escalate only when blocked or quality poor.
+
+## Escalation triggers
+- Repeated failed attempts.
+- Ambiguous requirements.
+- Cross-module side effects.
+- Security-critical code paths.
+
+## De-escalation triggers
+- Routine CRUD edits.
+- Mechanical refactors.
+- Artifact writing.
+- Status/timeline updates.
+
+## Required behavior
+- Record chosen model class in artifact header when work is non-trivial.
+- Keep outputs concise to reduce token burn.
+- If `harness/project.config.json` has `model_mode=lean`, prefer tiny/small whenever possible.

+## 📐 Propósito
+
+- **SDD**: Documenta el diseño técnico del sistema (arquitectura, componentes, decisiones).
+- **BDD**: Documenta el comportamiento esperado desde la perspectiva del usuario/negocio.
+
+Ambos alimentan el pipeline de agentes y se versionan junto con el código.

+## 🔄 Flujo de trabajo SDD/BDD en ARNES
+
+### Stage: design (architect)
+
+1. **Crear/actualizar SDD**
+   - Definir componentes nuevos
+   - Documentar decisiones técnicas
+   - Crear ADRs cuando haya cambios
+
+2. **Crear/actualizar BDD**
+   - Traducir requisitos de `spec/product.md` a Gherkin
+   - Crear scenarios para cada criterio de aceptación
+   - Asegurar que cada scenario tenga link a `@F-XXX`
+
+3. **Producir artefacto**
+   - Archivo: `work/artifacts/<feature_id>/architect.md`
+   - Contenido: resumen de cambios en SDD/BDD
+
+### Stage: build (implementer)
+
+1. **Implementar código** que cumpla los scenarios BDD
+2. **Escribir tests** que ejecuten los scenarios
+3. **Actualizar SDD** si hay cambios en componentes
+
+### Stage: review_gate (reviewer)
+
+1. **Verificar** que el código implementa lo documentado en SDD
+2. **Verificar** que tests cubren los scenarios BDD
+3. **Producir** `work/artifacts/<feature_id>/reviewer.json`
+
+### Stage: qa_gate (qa)
+
+1. **Ejecutar** tests BDD (feature files)
+2. **Verificar** trazabilidad: todos los `@F-XXX` tienen tests
+3. **Producir** `work/artifacts/<feature_id>/qa.json`
+

+# ADR-002: Almacenamiento de Avatares
+
+## Estado
+Aceptado
+
+## Fecha
+2026-05-06
+
+## Contexto
+Los usuarios pueden subir avatares personalizados. Necesitamos decidir dónde y cómo almacenar las imágenes de perfil para optimizar costo, rendimiento y mantenimiento.
+
+## Decisión
+Usar **Storage Service externo (S3-compatible)** con URLs firmadas para avatares.
+
+## Justificación
+1. **Simplicidad**: No requerimos procesar imágenes en nuestro servidor
+2. **Costo**: S3-like storage es económico ($0.023/GB)
+3. **CDN**: Los avatares se sirven desde CDN automáticamente
+4. **Seguridad**: URLs firmadas con expiración evitan hotlinking
+5. **Mantenimiento**: No requiere gestión de sistema de archivos
+
+## Consecuencias
+
+### ✅ Positivas
+- No hay infraestructura de archivos que mantener
+- Escalabilidad automática
+- URLs firmadas = más seguridad
+- Cache CDN = mejor performance
+
+### ❌ Negativas
+- Dependencia de proveedor externo
+- Costo de storage + egress
+- Latencia extra por redirect a CDN
+
+### 🔄 Neutrales
+- Requiere configuración de CORS
+
+## Alternativas Consideradas
+
+### Opción A: Almacenamiento local en servidor
+- **Pros**: Sin dependencia externa, rápido para lecturas
+- **Contras**: No escala horizontalmente, requiere backup, problemas de disco
+- **Razón de descarte**: No escala bien con múltiples instancias
+
+### Opción B: Base de datos como BLOB
+- **Pros**: Todo en un lugar, transacciones integradas
+- **Contras**: PostgreSQL no optimizado para archivos grandes, backup lento
+- **Razón de descarte**: degrada performance de DB, backups muy pesados
+
+### Opción C: Servicio dedicado de imágenes (Cloudinary/Imgix)
+- **Pros**: Transformación de imágenes, CDN incluido, optimización automática
+- **Contras**: Más costoso ($50+/mes), vendor lock-in
+- **Razón de descarte**: Over-engineering para avatares simples
+
+## Implementación
+
+1. Cliente sube imagen a `/api/v1/profile/upload` (multipart)
+2. Servicio valida tipo (jpg/png/webp) y tamaño (<5MB)
+3. Servicio sube a S3 con nombre `avatars/{user_id}/{timestamp}.{ext}`
+4. Servicio genera URL firmada (7 días validez)
+5. URL se guarda en campo `avatar_url` del perfil
+
+## Notas
+- Considerar WebP en el futuro para optimización
+- Implementar cleanup de avatares huérfanos (job semanal)
+

+# ADR-003: Hashing de Contraseñas
+
+## Estado
+Aceptado
+
+## Fecha
+2026-05-06
+
+## Contexto
+Necesitamos guardar contraseñas de usuarios de forma segura. La decisión debe considerar:
+- Resistencia a ataques de fuerza bruta y rainbow tables
+- Performance (se ejecuta en cada login y cambio de password)
+- Compatibilidad con estándares de la industria
+
+## Decisión
+Usar **bcrypt** con cost factor 12 para hashing de contraseñas.
+
+## Justificación
+1. **bcrypt** es diseñado específicamente para password hashing lento
+2. **Cost factor configurable**: permite aumentar resistencia en el futuro
+3. **Resistente a GPU/rainbow attacks**: diseñado para ser lento intencionalmente
+4. **Incorpora salt**: cada password tiene salt único, evitando rainbow tables
+5. **Estándar de industria**: ampliamente usado (Django, Rails, bcrypt)
+
+## Consecuencias
+
+### ✅ Positivas
+- Resistente a ataques de fuerza bruta
+- Salt automático evitar rainbow tables
+- Configurable (cost factor)
+- Librerías maduras en todos los lenguajes
+
+### ❌ Negativas
+- Más lento que MD5/SHA (es el punto, pero afecta latency)
+- Enorme payload si se guarda en cookies/token
+
+### 🔄 Neutrales
+- Requiere Python 3.11+ para bcrypt moderno
+
+## Implementación
+
+```python
+import bcrypt
+
+def hash_password(password: str) -> str:
+    """Hash password with bcrypt, cost 12."""
+    return bcrypt.hashpw(
+        password.encode('utf-8'), 
+        bcrypt.gensalt(rounds=12)
+    ).decode('utf-8')
+

+    return bcrypt.checkpw(
+        password.encode('utf-8'), 
+        hashed.encode('utf-8')
+    )
+```
+
+## Alternativas Consideradas
+
+### Opción A: SHA-256 (con salt)
+- **Pros**: Rápido, simple
+- **Contras**: No es lento, vulnerable a GPU attacks, diseñado para speed no security
+- **Razón de descarte**: No es resistente a hardware moderno
+
+### Opción B: Argon2
+- **Pros**: Ganador PHC 2015, configurable memory/CPU
+- **Contras**: Más complejo de implementar, menos soporte de librerías
+- **Razón de descarte**: bcrypt es más simple y suficiente para nuestro caso de uso
+
+### Opción C: scrypt
+- **Pros**: Diseñado para ser memory-hard
+- **Contras**: Más lento de configurar, configuración compleja
+- **Razón de descarte**: bcrypt es más simple y ampliamente soportado
+
+## Notas
+- Si en el futuro，我们需要 mayor seguridad, migrar a Argon2
+- No guardar passwords en logs bajo ninguna circunstancia

+# ADR-004: JWT Authentication Strategy
+
+## Status
+ACCEPTED
+
+## Context
+We need a stateless authentication mechanism for the API that:
+1. Allows users to login with email/password
+2. Provides secure token-based sessions
+3. Supports token revocation (logout)
+4. Handles token refresh without re-login
+
+## Decision
+
+We will use **JWT (JSON Web Tokens)** with the following configuration:
+
+### Token Structure
+- **Access Token**: 15 minute expiration, contains user identity
+- **Refresh Token**: 7 day expiration, used to obtain new access tokens
+
+### Algorithm
+- **HS256** for signing (symmetric, simpler setup)
+- Secret key loaded from environment variable `JWT_SECRET`
+
+### Claims
+```json
+{
+  "sub": "user_uuid",
+  "email": "user@example.com",
+  "role": "user",
+  "iat": 1715030400,
+  "exp": 1715031300,
+  "jti": "unique-token-id"
+}
+```
+
+### Session Management
+- Active sessions tracked in **Redis** (keyed by `jti`)
+- Sessions invalidated on logout
+- All user sessions invalidated on password change (from F-003)
+
+## Consequences
+
+### Positive
+- Stateless = horizontal scaling friendly
+- Short-lived access tokens limit damage if compromised
+- Refresh tokens allow long sessions without storing passwords
+- Redis-based session tracking enables instant revocation
+
+### Negative
+- Cannot revoke individual refresh tokens (need blocklist)
+- Token size larger than session IDs
+- Clock sync required between services
+
+## Alternatives Considered
+
+| Alternative | Why Rejected |
+|-------------|--------------|
+| Session cookies | Not API-friendly, CSRF issues |
+| OAuth2/OIDC | Overkill for simple auth |
+| PASETO | Less battle-tested |
+| opaque tokens | Requires DB lookup on every request |
+
+## Implementation Notes
+- JWT library: PyJWT
+- Redis client: aioredis for async
+- Both tokens stored in HttpOnly cookies for browser clients
+- Access token in Authorization header for API clients

+# Starter Pack (rápido)
+
+Este pack sirve para arrancar ARNES en 2 escenarios:
+
+## A) Proyecto nuevo (greenfield)
+1. Crea repo vacío.
+2. Copia el template ARNES.
+3. Ajusta `backlog/features.json` (`project`, `description`).
+4. Copia `starter-pack/backlog.features.bootstrap.json` como primera feature.
+5. Ejecuta:
+   - `./scripts/verify.sh`
+   - `python3 scripts/agent_status.py show`
+
+## B) Proyecto ya empezado (brownfield)
+1. Copia **solo** carpetas core ARNES: `harness/`, `spec/`, `backlog/`, `work/`, `scripts/`, `platforms/`.
+2. Mantén tu código actual intacto.
+3. Añade checks del dominio en `scripts/verify.local.sh`.
+4. Define features reales del proyecto en `backlog/features.json`.
+5. Ejecuta:
+   - `./scripts/verify.sh`
+   - `python3 scripts/agent_status.py show`
+
+## Reglas mínimas
+- 1 sola feature en `in_progress`.
+- `done` requiere gates: `review/security/qa`.
+- Evidencia en `work/artifacts/<feature_id>/`.
