Vamos a dise帽arlo como arquitectura t茅cnica en tres capas: **Esc谩ner (detecci贸n) → Motor de puntuaci贸n (candidatos a purga) → Registro blockchain (algoritmos y certificados que pasan)**. Incluyo pseudoc贸digo seguro (detecci贸n, no explotaci贸n), el dise帽o del contrato inteligente y las salvaguardas legales.
> **Advertencia 茅tica y legal:** este dise帽o es para **auditor铆a autorizada y escaneo pasivo de informaci贸n p煤blica**. No incluye explotaci贸n de vulnerabilidades. Todo escaneo activo requiere autorizaci贸n escrita del propietario; el pasivo respeta `robots.txt`, limita la tasa de peticiones y no accede a datos personales. El escaneo no autorizado puede ser delito (art. 197 bis CP en Espa帽a y equivalente en la UE).

# 馃攳 CAPA 1 — ALGORITMO ESC脕NER
## 1.1. Fases del esc谩ner
| Fase | Qu茅 hace | T茅cnica | Autorizaci贸n |
|---|---|---|---|
| **A. Descubrimiento** | Enumera objetivos | Certificate Transparency (crt.sh), DNS, sitemaps, Common Crawl, registros sectoriales | P煤blico |
| **B. Fingerprinting pasivo** | Identifica tecnolog铆a sin tocar el servidor | Cabeceras HTTP, HTML, JS, cookies, certificado TLS | P煤blico |
| **C. An谩lisis de certificados** | Detecta obsolescencia criptogr谩fica | X.509, OCSP/CRL, CT logs, TLS handshake | P煤blico |
| **D. Detecci贸n de c贸digo obsoleto** | Versiones de CMS, librer铆as, dependencias | Huellas (hashes, SRI), rutas conocidas, metadatos | P煤blico |
| **E. Correlaci贸n EOL/CVE** | Cruza versiones con bases de datos | endoflife.date API, NVD, CPE matching | P煤blico |
| **F. Sonda activa (opcional)** | Confirma versi贸n exacta | `OPTIONS`, `HEAD`, well-known paths, banner seguro | **Solo con autorizaci贸n escrita** |
## 1.2. Pseudoc贸digo del esc谩ner (seguro, sin explotaci贸n)
```python
# purge_engine/scanner.py — pseudoc贸digo conceptual
FUENTES_DESCUBRIMIENTO = ["crt_sh", "dns_enum", "sitemap", "common_crawl", "registro_sectorial"]

h.eol = endoflife_date_api(h.producto, h.version)
h.cves = nvd_por_cpe(h.producto, h.version)
return hallazgos
```
## 1.3. Firmas de detecci贸n (ejemplos de reglas, no exploits)
| Se帽al detectada | Significado | Peso |
|---|---|---|
| `X-Powered-By: PHP/5.x` | PHP EOL | Alto |
| `<meta name="generator" content="WordPress 4.x">` | CMS sin soporte | Alto |
| Certificado firmado con SHA-1 o MD5 | Criptograf铆a rota | Cr铆tico |
| RSA < 2048 bits o TLS 1.0/1.1 | Transporte inseguro | Cr铆tico |
| Ausencia de HSTS / CSP | Configuraci贸n d茅bil | Medio |
| Librer铆a JS con hash conocido obsoleto (jQuery <3.x) | Dependencia vulnerable | Alto |
| `composer.lock` o `.env` accesibles | Exposici贸n de secretos | Cr铆tico |
| OCSP responde "revocado" | Certificado inv谩lido | Cr铆tico |
| Sin registro en CT logs | Certificado no auditado | Medio |
| Source maps expuestos | Fuga de c贸digo | Medio |
---
# 馃М CAPA 2 — MOTOR DE PUNTUACI脫N (PCS: Purge Candidate Score)
## 2.1. F贸rmula
El PCS es una puntuaci贸n de **0 a 100** (a mayor valor, m谩s candidato a purga). Se calcula como suma ponderada y normalizada:
```
PCS = 100 × 危 (w_i × s_i) / 危 w_i
Donde s_i ∈ [0,1] por factor y w_i es el peso del factor.
```
| Factor | Peso (w) | C谩lculo de s (0–1) |
|---|---|---|
| **EOL del software** | 25 | 1 si EOL; 0.7 si EOL <6 meses; 0 si soportado |
| **CVE cr铆ticos/altos abiertos** | 20 | `min(1, CVSS_medio/10)`, penaliza CVSS≥9 |
| **Obsolescencia criptogr谩fica** | 15 | SHA-1/MD5, RSA<2048, TLS 1.0/1.1, cert revocado |
| **Exposici贸n de secretos/config** | 10 | 1 si `.env`, `composer.lock`, backups accesibles |
| **Dependencias JS/CMS obsoletas** | 10 | Proporci贸n de librer铆as sin soporte |
| **Cabeceras de seguridad ausentes** | 5 | HSTS, CSP, X-Frame-Options |
| **Accesibilidad/rendimiento** | 5 | Core Web Vitals en rojo, WCAG <AA |
| **Soberan铆a de datos** | 5 | Datos no exportables, dependencia de proveedor |
| **Sin registro CT / OCSP** | 5 | Certificado no auditado |
## 2.2. Categor铆as de purga
| PCS | Categor铆a | Acci贸n sugerida |
|---|---|---|
| **81–100** | 馃敶 **Purga inmediata** | Bloqueo/desindexaci贸n por agentes IA; notificaci贸n urgente |
| **61–80** | 馃煚 **Purga programada** | Plazo de subsanaci贸n 30 d铆as; re-auditor铆a |
| **41–60** | 馃煛 **Revisi贸n** | Auditor铆a manual; plan de mejora |
| **21–40** | 馃煝 **Apto** | Certificable en nivel Bronce/Plata |
| **0–20** | 馃煝 **Certificable** | Candidato a Oro |
## 2.3. Regla de oro (coherente con tu metodolog铆a)
> **Ning煤n factor cr铆tico puede anular la puntuaci贸n global.** Un sitio con PCS 15 pero con un CVE cr铆tico abierto se reclasifica autom谩ticamente a **"Purga inmediata"**. La excelencia media no compensa un fallo cr铆tico.
## 2.4. Salida del motor (JSON de evidencia)
```json
{
"objetivo": "ejemplo.eus",
"fecha": "2026-11-01T10:00:00Z",
"pcs": 78,
"categoria": "purga_programada",
"factores": {
"eol": {"valor": 1, "detalle": "PHP 7.4 EOL 2022-11-28"},
"cve": {"valor": 0.72, "detalle": ["CVE-2024-XXXX CVSS 9.8"]},
"cripto": {"valor": 1, "detalle": "TLS 1.0, SHA-1"},
"secretos": {"valor": 0, "detalle": "sin exposici贸n"},

},
"hash_evidencia": "sha256:9f2a...",
"ruleset_version": "v1.3.0",
"autorizacion": "pasivo"
}
```
El `hash_evidencia` y el `ruleset_version` son la base de lo que se registra en blockchain.

# ⛓️ CAPA 3 — BLOCKCHAIN: REGISTRO DE ALGORITMOS Y CERTIFICADOS
## 3.1. Qu茅 se registra on-chain (y qu茅 no)
| On-chain (inmutable, p煤blico) | Off-chain (IPFS/Arweave, privado o cifrado) |
|---|---|
| Hash del informe de auditor铆a | Informe completo |
| Hash del dominio (no el dominio en claro, por privacidad) | Dominio real (cifrado, acceso restringido) |
| PCS y categor铆a | Detalle de factores y CVEs |
| Nivel de certificaci贸n (Bronce/Plata/Oro) | Evidencias t茅cnicas |
| Versi贸n del ruleset del esc谩ner | C贸digo del esc谩ner |
| DID del auditor y del Consejo T茅cnico | Identidades completas |
| Timestamp, caducidad, estado | Comunicaciones |
| Hash del algoritmo/software auditado | Binarios o c贸digo fuente |
**Principio:** on-chain solo lo m铆nimo verificable; nunca datos personales ni detalles explotables.
## 3.2. Dos registros complementarios
**A. `RulesetRegistry` — "los algoritmos que est谩n actualizados"**
Cada versi贸n del motor de escaneo (reglas, firmas, umbrales) se registra con su hash. As铆 se puede probar **con qu茅 versi贸n del algoritmo** se certific贸 cada servicio y detectar rulesets obsoletos.
**B. `CertificateRegistry` — "los que pasan la purga"**
Cada certificado emitido referencia: hash del informe, PCS, nivel, ruleset usado, auditor, caducidad y estado (vigente/suspendido/revocado).
## 3.3. Contrato inteligente (Solidity, esquema conceptual)
```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;
/// @title Registro PASAIA LAB — Rulesets y Certificados
contract PurgaRegistry {

}

function verificar(bytes32 _hashDominio)
external view
returns (bool vigente, uint8 nivel, uint8 pcs, bytes32 rulesetHash, uint256 caducidad)
{
Certificado memory c = certificados[_hashDominio];
vigente = (c.estado == Estado.Vigente && c.caducidad > block.timestamp);
return (vigente, c.nivel, c.pcs, c.rulesetHash, c.caducidad);
}
}
```
## 3.4. Modelo de consenso y red (h铆brido)
| Capa | Tecnolog铆a sugerida | Motivo |
|---|---|---|
| **Escritura** | Red permissioned (Hyperledger Besu / Fabric) | Solo auditores autorizados escriben; velocidad y control |
| **Lectura/verificaci贸n** | Anclaje peri贸dico en L2 p煤blica (Polygon/Base) | Verificaci贸n p煤blica sin coste alto; resistencia a censura |
| **Almacenamiento** | IPFS/Arweave para informes cifrados | Descentralizado, barato, verificable por hash |
| **Identidad** | DIDs (did:ethr o did:key) para auditores y Consejo | Trazabilidad sin exponer datos personales |
**Flujo:** el esc谩ner produce evidencia → el auditor firma → el contrato emite el certificado → el hash se ancla en L2 p煤blica → cualquiera verifica con el `hashDominio`.
## 3.5. Verificaci贸n p煤blica del sello (usuario final)
1. El badge incluye un QR o enlace con el `hashDominio`.
2. La web de verificaci贸n consulta `verificar(hashDominio)` en el contrato.
3. Devuelve: vigente / nivel / PCS / ruleset / caducidad.
4. Enlaza al informe off-chain solo si el cliente lo autoriz贸.
5. Si el ruleset usado est谩 marcado como obsoleto, se muestra advertencia: **"Certificado con algoritmo v1.2.0; revisar con v1.3.0"**.

```
---
# 馃洝️ SALVAGUARDAS LEGALES Y 脡TICAS (obligatorias)
1. **Autorizaci贸n escrita** para escaneo activo; el pasivo respeta `robots.txt` y limita a 1 req/s por host.
2. **No explotaci贸n**: el esc谩ner detecta versiones y configuraciones, nunca ejecuta exploits.
3. **RGPD**: no se recogen datos personales; los dominios se hashean con salt; informes cifrados.
4. **Divulgaci贸n responsable**: hallazgos cr铆ticos se notifican al propietario 30 d铆as antes de publicar.
5. **Derecho de r茅plica**: el certificado puede impugnarse ante el Consejo T茅cnico; la decisi贸n se publica.
6. **Tasa y cortes铆a**: backoff exponencial, identificaci贸n con user-agent propio, respeto a `Retry-After`.
7. **Transparencia del ruleset**: cada versi贸n del esc谩ner es p煤blica y auditable; el hash on-chain lo prueba.

# 馃帹 (c) PROMPT DE IMAGEN — ARQUITECTURA "PURGA ENGINE"
## Versi贸n horizontal 16:9 (para entrada de blog)
```text
Genera una imagen editorial horizontal 16:9 para un art铆culo t茅cnico titulado:
"PURGA ENGINE: ESC脕NER, PUNTUACI脫N Y REGISTRO BLOCKCHAIN".
Concepto central:
Un diagrama de arquitectura visual y elegante en tres capas horizontales superpuestas, de abajo arriba o de izquierda a derecha, que represente el flujo del sistema. Debe leerse como un esquema t茅cnico, no como una ilustraci贸n b茅lica.
Composici贸n por capas:
- CAPA 1 (izquierda): un esc谩ner digital representado por un radar o lente luminosa que barre una red de nodos grises (webs, intranets, certificados). Algunos nodos muestran iconos de advertencia: candados roto, engranajes oxidados, hojas de c贸digo con signos de EOL. Colores grises y rojos.
- CAPA 2 (centro): un medidor o dial de puntuaci贸n (PCS) con escala de 0 a 100, donde la aguja marca una zona naranja-roja. Alrededor del dial, peque帽as etiquetas flotantes: "EOL", "CVE", "TLS", "Secretos", "Deps". El dial tiene detalles en rojo vibrante y gris carb贸n.
- CAPA 3 (derecha): una cadena de bloques estilizada, formada por cubos luminosos conectados, cada uno con un hash abreviado (tipo "0x9f2a...") y un peque帽o candado de verificaci贸n. Sobre los bloques, dos etiquetas: "RULESETS" y "CERTIFICADOS". Colores blancos, grises met谩licos y detalles en rojo.
- Conectando las tres capas, flechas finas rojas y l铆neas de datos que fluyen de izquierda a derecha, con peque帽os paquetes de evidencia (hashes) viajando por ellas.
- En el centro geom茅trico de la composici贸n, una gran "X" roja estilizada y semitransparente, con fuerte presencia, como sello de identidad de PASAIA LAB. No debe parecer el logotipo de una red social, sino una X geom茅trica propia.
- Fondo general difuminado con c贸digo binario verde Matrix (#00FF00) muy desenfocado, efecto bokeh, solo como sustrato tecnol贸gico.
- En la parte superior, deja espacio limpio. Si incluyes texto, que sea grande y legible: "PURGA ENGINE" y debajo, m谩s peque帽o: "Esc谩ner · Puntuaci贸n · Blockchain".
- En una esquina inferior, texto peque帽o en gris: "PASAIA LAB / INTELIGENCIA LIBRE / ACCI脫N CIVIL DIGITAL y FORJA".
Paleta:
Blanco puro, gris claro, gris carb贸n, rojo vibrante (#FF0000) y verde Matrix (#00FF00) solo en el fondo difuminado.
Estilo:
Editorial, t茅cnico, limpio, alto contraste, iluminaci贸n cinematogr谩fica suave, sombras sutiles. El diagrama de tres capas y la X roja deben ser los protagonistas. Evita marcas reales, logotipos de empresas, saturaci贸n excesiva, aspecto de cartel b茅lico y texto ilegible.
```
## Versi贸n cuadrada 1:1 (para gadget de Blogger)
```text
Genera una imagen cuadrada 1:1 (1080x1080 px) para un gadget lateral de blog titulado:
"PURGA ENGINE".
Composici贸n adaptada a formato cuadrado:
- Organiza las tres capas en vertical, de arriba abajo, ocupando cada una un tercio de la imagen:
· Tercio superior: esc谩ner/radar barriendo una red de nodos grises con iconos de advertencia (candados rotos, engranajes oxidados, etiquetas "EOL").
· Tercio central: dial de puntuaci贸n PCS (0–100) con aguja en zona naranja-roja y etiquetas flotantes "CVE", "TLS", "Secretos".
· Tercio inferior: cadena de bloques estilizada con cubos luminosos, hashes abreviados y etiquetas "RULESETS" y "CERTIFICADOS".
- Flechas finas rojas conectan los tres tercios de arriba abajo.
- En el centro de la imagen, una gran "X" roja estilizada y semitransparente, con fuerte presencia, como sello de identidad.
- Fondo general difuminado con c贸digo binario verde Matrix (#00FF00) muy desenfocado, efecto bokeh.
- Deja un espacio limpio en la parte superior para a帽adir despu茅s el t铆tulo con un editor. Si incluyes texto, que sea breve: "PURGA ENGINE" y debajo, m谩s peque帽o: "Esc谩ner · Puntuaci贸n · Blockchain".
- En una esquina inferior, texto peque帽o en gris: "PASAIA LAB / INTELIGENCIA LIBRE / ACCI脫N CIVIL DIGITAL y FORJA".
Paleta:
Blanco puro, gris claro, gris carb贸n, rojo vibrante (#FF0000) y verde Matrix (#00FF00) solo en el fondo difuminado.
Estilo:
Editorial, t茅cnico, limpio, alto contraste, iluminaci贸n cinematogr谩fica suave. La X roja y el flujo vertical de las tres capas deben ser los protagonistas. Evita marcas reales, saturaci贸n excesiva y texto ilegible.

# 馃Л Ahora, (a) y (b): elige el orden
Ambos son entregables t茅cnicos sustanciales. Te resumo qu茅 incluir铆a cada uno para que decidas con criterio:
### (a) Repositorio esqueleto del esc谩ner en Python
**Qu茅 incluir铆a:**
- Estructura de carpetas (`purga_engine/`, `scanner/`, `scoring/`, `rulesets/`, `tests/`, `docs/`).
- `pyproject.toml` con dependencias m铆nimas y seguras (`httpx`, `cryptography`, `dnspython`, `pydantic`, `pytest`).
- M贸dulos vac铆os o con stubs firmados: `discovery.py`, `fingerprint.py`, `tls_analysis.py`, `eol_cve.py`, `scoring.py`, `evidence.py`.
- Reglas de detecci贸n en YAML (firmas de obsolescencia, sin exploits).
- Tests unitarios con datos sint茅ticos (sin escanear objetivos reales).
- `README.md` con filosof铆a 茅tica, l铆mites de uso y c贸mo ejecutar en modo pasivo.
- `Dockerfile` y `.gitignore`.
- **Sin c贸digo de explotaci贸n**, solo detecci贸n.
**Utilidad:** te da una base real para empezar a programar y para presentar el proyecto como algo tangible a socios t茅cnicos.
### (b) Contrato desplegable en testnet con scripts
**Qu茅 incluir铆a:**
- Contrato `PurgaRegistry.sol` completo y comentado (el que ya esbozamos, ampliado).
- Contrato auxiliar `RulesetRegistry.sol` si se separa.
- Tests en Hardhat/Foundry (emisi贸n, verificaci贸n, revocaci贸n, permisos).
- Scripts de despliegue a **Sepolia** o **Polygon Amoy** (testnets p煤blicas).
- Scripts de interacci贸n: registrar ruleset, emitir certificado, verificar, revocar.
- `README.md` con pasos exactos: instalar, compilar, testear, desplegar, verificar en explorer.
- Variables de entorno (`.env.example`) sin claves reales.
**Utilidad:** tendr铆as un registro blockchain funcional en testnet en cuesti贸n de horas, verificable p煤blicamente y listo para el piloto.
------------------------------------------------------------------------------
Perfecto, amigo. Vamos con el **(b)**: un paquete completo y desplegable en testnet en una tarde. Te entrego el repositorio entero —contrato, configuraci贸n Hardhat, scripts, tests y README— para que solo tengas que clonar, rellenar el `.env` y desplegar.
> **Antes de nada:** este contrato es para **testnet** (Sepolia o Polygon Amoy). No uses claves de mainnet ni cuentas con fondos reales. En producci贸n conviene una auditor铆a externa y, si se quiere evolucionar, un patr贸n proxy (UUPS).

# 5. README (pasos exactos)
**`README.md`**
```markdown
# PurgaRegistry — PASAIA LAB
Registro on-chain de rulesets y certificados de la Secci贸n Certificaci贸n.
## Requisitos
- Node.js 20+
- Una wallet de testnet con fondos de faucet
## Instalaci贸n
```bash
npm install
cp .env.example .env
# rellena PRIVATE_KEY y los RPC en .env
```
## Compilar y testear
```bash
npm run compile
npm test
```
## Desplegar en Polygon Amoy (recomendado: gas gratis)
1. Consigue POL de testnet en https://faucet.polygon.technology/
2. Rellena `.env` con `PRIVATE_KEY` y `AMOY_RPC_URL`.
3. Despliega:
```bash
npm run deploy:amoy
```
4. Anota la direcci贸n que aparece y gu谩rdala en `deployments/amoy.json`.
## Desplegar en Sepolia
1. Consigue ETH de testnet en https://sepoliafaucet.com/
2. Rellena `.env` con `PRIVATE_KEY` y `SEPOLIA_RPC_URL`.
3. Despliega:
```bash
npm run deploy:sepolia
```
## Flujo de demo
```bash
# 1. Registrar el ruleset v1.0.0
npm run ruleset:amoy
# 2. Emitir un certificado para ejemplo.eus (PCS 15, nivel Oro)
npm run issue:amoy
# 3. Verificar
npm run verify:amoy
# 4. Revocar (opcional)
CERT_ID=0x... MOTIVO=demo npm run revoke:amoy
```
## Verificar el contrato en el explorer
```bash
npx hardhat verify --network amoy <DIRECCION>
```
## Roles
- `DEFAULT_ADMIN_ROLE`: gestiona roles y pausa.
- `AUDITOR_ROLE`: registra rulesets y emite certificados.
- `COUNCIL_ROLE`: suspende, revoca y reactiva certificados.
En producci贸n, separa las direcciones: admin, auditor y consejo no deben ser la misma.
## Seguridad
- Contrato para testnet. No usar en mainnet sin auditor铆a externa.
- El informe completo va off-chain (IPFS/Arweave). On-chain solo hash y metadatos.
- El `hashDominio` se calcula con salt para no exponer el dominio en claro.
## Licencia
MIT

# 6. COSTE Y ALTERNATIVAS
| Red | Coste despliegue | Coste emitir certificado | Notas |
|---|---|---|---|
| **Polygon Amoy** (testnet) | 0 (faucet) | 0 (faucet) | Recomendado para demo |
| **Sepolia** (testnet) | 0 (faucet) | 0 (faucet) | Alternativa Ethereum |
| **Polygon mainnet** | ~0,5–2 € | ~0,01–0,05 € | Producci贸n barata |
| **Base mainnet** | ~1–5 € | ~0,02–0,10 € | L2 con buena adopci贸n |
| **Ethereum mainnet** | ~50–200 € | ~1–5 € | Solo si se necesita m谩xima seguridad |
Para el piloto con un ayuntamiento, **Polygon Amoy es la opci贸n natural**: gas gratis, explorer p煤blico, y el certificado se puede verificar desde cualquier navegador sin wallet.
---
# 7. VERIFICACI脫N P脷BLICA EN EL EXPLORER
Una vez desplegado, cualquiera puede verificar un certificado sin conocer la web de PASAIA LAB:
1. Abre `https://amoy.polygonscan.com/address/<DIRECCION>#readContract`
2. Ve a **`verify`**
3. Introduce el `hashDominio` (calculado como `keccak256(dominio + salt)`)
4. Pulsa **"Query"** y obtendr谩s: vigente, ruleset obsoleto, nivel, PCS, certId, rulesetHash, caducidad.
Eso es la prueba demostrable para un ayuntamiento: **"este certificado est谩 registrado on-chain y cualquiera puede verificarlo sin depender de nosotros"**.

# 馃摐 CERTIFICACI脫N DEL ENTREGABLE
**Se certifica que el repositorio `purga-registry` descrito —contrato `PurgaRegistry.sol` con separaci贸n de roles auditor/consejo/admin, scripts de despliegue, emisi贸n, verificaci贸n y revocaci贸n, y suite de tests— constituye un MVP desplegable en testnet en menos de una jornada, t茅cnicamente coherente con la metodolog铆a PASAIA LAB y el Dec谩logo de ACCI脫N CIVIL DIGITAL.**
**Firmado:** Jos茅 Agust铆n Font谩n Varela — CEO de PASAIA LAB / INTELIGENCIA LIBRE / ACCI脫N CIVIL DIGITAL y FORJA.

## 馃Л Siguiente paso colegas ;)
Perfecto, amigo. Vamos con el **(a)**: el esqueleto completo del esc谩ner en Python. Es un repositorio **real, ejecutable y testeable**, pero con **stubs claramente marcados** donde hay servicios externos (CT logs, NVD, Common Crawl). Incluye salvaguardas 茅ticas desde el primer commit: modo pasivo por defecto, autorizaci贸n obligatoria para modo activo, rate limiting, respeto a `robots.txt` y **cero c贸digo de explotaci贸n**.
> **Principio rector:** el esc谩ner **detecta** versiones, configuraciones y certificados obsoletos; **nunca** explota vulnerabilidades. Todo hallazgo es una evidencia con hash reproducible.

**`README.md`**
```markdown
# Purga Engine — PASAIA LAB
Esc谩ner de obsolescencia y motor PCS (Purge Candidate Score) para identificar
servicios candidatos a la "Gran Purga Algor铆tmica" de Internet.
## Filosof铆a
- **Detecci贸n, no explotaci贸n.** El esc谩ner lee cabeceras, HTML, certificados y
versiones p煤blicas. **Nunca** ejecuta exploits.
- **Pasivo por defecto.** El modo `active` requiere un archivo de autorizaci贸n
firmado por el propietario del servicio.
- **Respeto al objetivo.** Rate limit de 1 req/s por host, `robots.txt`,
User-Agent identificativo, timeout de 10 s.
- **Transparencia.** Cada evidencia incluye el hash del informe y la versi贸n del
ruleset usado, para que pueda verificarse on-chain (contrato `PurgaRegistry`).
## Instalaci贸n
```bash
git clone <repo> && cd purga-engine
python -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"
cp .env.example .env
```
## Uso
```bash
# Demo sin red (fixture sint茅tico)
purga-engine scan --target ejemplo.eus --mode synthetic
# Pasivo sobre un dominio (respeta robots.txt)
purga-engine scan --target ejemplo.eus --mode passive
# Activo (requiere autorizaci贸n escrita)
purga-engine scan --target ejemplo.eus --mode active --authorization auth.txt
```
La evidencia se guarda en `reports/<target>.json` con:
- `findings`: hallazgos individuales
- `score.pcs`: 0–100
- `score.category`: `purge_immediate` | `purge_scheduled` | `review` | `apt` | `certifiable`
- `score.critical_flags`: CVEs ≥9.0, secretos expuestos, TLS d茅bil…
- `hash_dominio` y `hash_evidencia`: para registrar on-chain
## Estructura
- `src/purga_engine/` — c贸digo
- `rulesets/v1.0.0/` — firmas, pesos y umbrales versionados
- `tests/` — suite de tests (sin red, con fixtures)
## Tests
```bash
pytest -q
```
## Docker
```bash
docker compose run --rm purga scan --target ejemplo.eus --mode synthetic
```
## Limitaciones conocidas
- `discovery.from_common_crawl` y `eol_cve.get_cves` son **stubs**: en producci贸n
conviene integrarlos con Common Crawl y CPE matching de NVD.
- El modo `active` est谩 deliberadamente limitado a sondas seguras (`OPTIONS`,
`HEAD`); no incluye explotaci贸n.
- La verificaci贸n OCSP/CRL est谩 en el roadmap.

# 17. C脫MO EJECUTAR LA DEMO
```bash
cd purga-engine
python -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"
cp .env.example .env
# Demo reproducible, sin red:
purga-engine scan --target legacy.example.eus --mode synthetic
# Salida esperada (resumen):
# ✅ Evidencia guardada en ./reports/legacy.example.eus.json
# PCS: 78.4
# Categor铆a: purge_immediate
# Hash evidencia: 0x...
# Hash dominio: 0x...
# ⚠️ Flags cr铆ticos: SECRET_ENV, TLS_WEAK_VERSION, CERT_WEAK_SIG, CERT_WEAK_KEY
```
El JSON resultante tiene exactamente los campos que el contrato `PurgaRegistry` espera: `hash_dominio`, `hash_evidencia`, `score.pcs`, `score.category`, `ruleset_version`. **Est谩 listo para emitir un certificado on-chain con los scripts del paso (b).**

**Se certifica que el repositorio `purga-engine` descrito —con m贸dulos de descubrimiento pasivo, fingerprinting, an谩lisis TLS, correlaci贸n EOL/CVE, motor PCS determinista, construcci贸n de evidencias hasheables y guardarra铆les 茅ticos— constituye un esqueleto t茅cnico ejecutable, testeable y coherente con la metodolog铆a de certificaci贸n de PASAIA LAB, el contrato `PurgaRegistry` y el Dec谩logo de ACCI脫N CIVIL DIGITAL. No contiene c贸digo de explotaci贸n.**
**Firmado:** Jos茅 Agust铆n Font谩n Varela — CEO de PASAIA LAB / INTELIGENCIA LIBRE / ACCI脫N CIVIL DIGITAL y FORJA.

## 馃Л Siguiente paso sugerido
Con el contrato desplegado en Amoy **(b)** y el esc谩ner esqueleto **(a)** listos, el flujo completo ya es demostrable:
```
purga-engine scan --mode synthetic → reports/x.json
↓
scripts/issue-certificate.js (lee hash_dominio, hash_evidencia, pcs, nivel)
↓
certificado verificable en amoy.polygonscan.com
```
-------------------------------------------------- ;)
Perfecto, amigo. Aqu铆 tienes la **integraci贸n end-to-end**: tres scripts nuevos, actualizaci贸n del `package.json`, README y un wrapper bash para demostrar el piloto en una sola sesi贸n. El flujo queda as铆:
```
purga-engine scan --mode synthetic → reports/x.json
↓
npx hardhat run scripts/issue-from-report.js --network amoy -- --report reports/x.json
↓
certificado verificable en amoy.polygonscan.com
↓
npx hardhat run scripts/verify-from-report.js --network amoy -- --report reports/x.json
```

# 5. ACTUALIZACI脫N DEL `README.md`
A帽ade esta secci贸n al final del README existente:
```markdown
## Integraci贸n end-to-end (esc谩ner → contrato)
El flujo completo del piloto se demuestra en tres pasos:
### Paso 1: escanear
```bash
purga-engine scan --target legacy.example.eus --mode synthetic
# → reports/legacy.example.eus.json
```
### Paso 2: emitir certificado desde el reporte
```bash
npx hardhat run scripts/issue-from-report.js --network amoy -- \
--report reports/legacy.example.eus.json \
--expires-days 365
```
El script:
- Valida la estructura del reporte (campos, hashes bytes32, PCS num茅rico).
- Comprueba que el firmante tiene `AUDITOR_ROLE`.
- Resuelve el `rulesetHash` on-chain (acepta `1.0.0` y `v1.0.0`).
- Deriva el nivel (Bronce/Plata/Oro) desde el PCS y la categor铆a.
- **Rechaza certificar** si hay flags cr铆ticos o la categor铆a es `purge_immediate` / `purge_scheduled`.
- Emite el certificado y guarda los metadatos en `deployments/certs/<certId>.json`.
Flags opcionales:
- `--dry-run`: simula sin enviar transacci贸n.
- `--allow-unsafe`: emite incluso si no es certificable (solo demo).
- `--expires-days N`: caducidad en d铆as (por defecto 365).
### Paso 3: verificar
```bash
npx hardhat run scripts/verify-from-report.js --network amoy -- \
--report reports/legacy.example.eus.json
```
O por `certId`:
```bash
npx hardhat run scripts/verify-from-report.js --network amoy -- \
--report reports/legacy.example.eus.json \
--cert-id 0x...
```
### Demo completa en una sesi贸n
```bash
NETWORK=amoy TARGET=legacy.example.eus MODE=synthetic bash scripts/demo-e2e.sh
```
### Mapeo PCS → nivel (MVP)
En esta fase, el nivel de certificaci贸n se deriva del PCS como proxy:
| PCS | Categor铆a | Nivel derivado |
|---|---|---|
| 0–20 | certifiable | **Oro** (3) |
| 21–40 | apt | **Plata** (2) |
| 41–60 | review | **Bronce** (1) |
| 61–80 | purge_scheduled | ❌ No certificable |
| 81–100 | purge_immediate | ❌ No certificable |
| cualquiera con flags cr铆ticos | — | ❌ No certificable |
En la fase 2, el esc谩ner emitir谩 adem谩s un `certification_score` de 5 dimensiones (seguridad, privacidad, eficiencia, accesibilidad, soberan铆a) que sustituir谩 al PCS como base del nivel. Mientras tanto, el proxy es conservador y transparente: el campo `nivelMotivo` del certificado registra por qu茅 se asign贸 cada nivel.
```

# 6. DEMO ESPERADA (salida resumida)
```bash

Ruleset: v1.0.0 → 0x1234...
Nivel derivado: 0 (flags cr铆ticos: SECRET_ENV, TLS_WEAK_VERSION, CERT_WEAK_SIG, CERT_WEAK_KEY)
Caducidad: 2027-11-01T00:00:00.000Z
⛔ No certificable: flags cr铆ticos: SECRET_ENV, TLS_WEAK_VERSION, CERT_WEAK_SIG, CERT_WEAK_KEY
Si aun as铆 quieres emitir (solo demo), a帽ade --allow-unsafe
```
**Ese es el comportamiento correcto**: el script **se niega a certificar** un sitio con secretos expuestos y TLS d茅bil. Es exactamente lo que un ayuntamiento querr铆a ver.
Si quieres ver el flujo completo con un fixture limpio, sustituye `legacy.example.eus` por `modern.example.eus` (que da PCS bajo y nivel Oro), o a帽ade `--allow-unsafe` para forzar la emisi贸n en la demo.

# 馃摐 CERTIFICACI脫N DEL ENTREGABLE
**Se certifica que la integraci贸n end-to-end descrita —`issue-from-report.js`, `verify-from-report.js` y `demo-e2e.sh`— conecta de forma determinista el esc谩ner Python con el contrato `PurgaRegistry`, valida la estructura del reporte, resuelve el ruleset on-chain con tolerancia al prefijo `v`, deriva el nivel de certificaci贸n con salvaguardas ante flags cr铆ticos, guarda metadatos off-chain en `deployments/certs/` y permite demostrar el piloto completo (escanear → emitir → verificar) en una sola sesi贸n.
