+# Fase 4 — CloudFront Function: Markdown for Agents
+
+Pasos para adjuntar `cloudfront-markdown-negotiation.js` a la distribución de Amplify.
+
+## Prerequisitos
+
+- AWS CLI configurado con permisos `cloudfront:*` en us-east-1
+- `index.md` ya desplegado en Amplify (Fase 1 completada)
+
+## Paso 1 — Obtener el Distribution ID de Amplify
+
+```bash
+# Opción A: via CLI de Amplify
+aws amplify list-apps --region us-east-1 --query 'apps[].{name:name,appId:appId}'
+
+# Opción B: buscar en CloudFront por dominio de origen
+aws cloudfront list-distributions \
+  --query "DistributionList.Items[?contains(to_string(Origins.Items[0].DomainName), 'amplifyapp')].{Id:Id,Domain:DomainName}" \
+  --output table
+```
+
+Guardar el `Distribution ID` (formato: `EXXXXXXXXXX`).
+
+## Paso 2 — Crear la CloudFront Function
+
+```bash
+# Crear la función en us-east-1 (requerido para CloudFront Functions)
+aws cloudfront create-function \
+  --name "uvdao-markdown-negotiation" \
+  --function-config "Comment=Rewrite to index.md for Accept:text/markdown,Runtime=cloudfront-js-2.0" \
+  --function-code fileb://infra/cloudfront-markdown-negotiation.js \
+  --region us-east-1
+
+# Guardar el FunctionARN del output (formato: arn:aws:cloudfront::ACCOUNT:function/uvdao-markdown-negotiation)
+```
+
+## Paso 3 — Publicar la función (pasarla de DEVELOPMENT a LIVE)
+
+```bash
+# Obtener el ETag de la función recién creada
+ETAG=$(aws cloudfront describe-function \
+  --name uvdao-markdown-negotiation \
+  --region us-east-1 \
+  --query 'ETag' --output text)
+
+# Publicar
+aws cloudfront publish-function \
+  --name uvdao-markdown-negotiation \
+  --if-match "$ETAG" \
+  --region us-east-1
+```
+
+## Paso 4 — Adjuntar al Distribution en viewer-request
+
+Hay que modificar el Default Cache Behavior del distribution para agregar la función.
+
+Amplify gestiona su distribución de CloudFront internamente. La forma más segura es hacerlo via la consola AWS, no via CLI, para evitar conflictos con el estado gestionado por Amplify.
+
+### Via consola AWS (recomendado)
+
+1. Ir a CloudFront → Distributions → `[Distribution ID de Paso 1]`
+2. Tab "Behaviors" → seleccionar el Default (`/*`) → Edit
+3. Bajar a "Function associations"
+4. En "Viewer request" seleccionar: Function type = **CloudFront Functions**, Function ARN = `arn:aws:cloudfront::ACCOUNT:function/uvdao-markdown-negotiation`
+5. Save changes
+6. Esperar a que el estado pase de "Deploying" a "Deployed" (~2-3 minutos)
+
+## Paso 5 — Verificar
+
+```bash
+# Debe retornar Content-Type: text/markdown y contenido markdown
+curl -sI -H "Accept: text/markdown" https://ultravioletadao.xyz/ | grep -i content-type
+curl -s  -H "Accept: text/markdown" https://ultravioletadao.xyz/ | head -5
+```
+
+Resultado esperado:
+```
+Content-Type: text/markdown
+# UltravioletaDAO
+```
+
+## Notas
+
+- Si Amplify hace un nuevo deploy, CloudFront puede resetear el cache behavior a sus defaults.
+  Verificar después de cada deploy que la función sigue asociada.
+- Alternativa sin CloudFront: agregar ruta `GET /index.md` en `api.ultravioletadao.xyz` que
+  retorne el contenido con `Content-Type: text/markdown`. Más mantenible pero requiere
+  Lambda update.
