 Actualizacion TASK-228, 2026-06-10: `/api/servers` deja de ser cache-only estricto y vuelve a ser near-real-time controlado para la home. Sirve snapshot fresco si existe; si no hay cache o esta stale, intenta RCON/A2S con timeout publico corto y degrada a snapshot stale o JSON controlado si live falla. `/api/servers/latest` e `/api/servers/history` siguen siendo lecturas de almacenamiento local, no sustitutos del estado live.
 
+Actualizacion TASK-229, 2026-06-10: los endpoints legacy agregados `/api/historical/server-summary?server=all-servers` y `/api/historical/recent-matches?server=all-servers&limit=20` dejan de ejecutar read model RCON o fallback runtime CRCON/PostgreSQL en lectura publica. Ahora son wrappers de los snapshots precomputados equivalentes, con `legacy_endpoint_policy=snapshot-read-only-fast-path`; si falta snapshot devuelven JSON controlado rapido en vez de agotar el timeout.

 Conclusiones principales:
 
 - El backend de `ranking` ya no muestra el cuello de botella grave del ranking anual. La evidencia mas fuerte es el test `backend/tests/test_annual_ranking_payload.py`, que confirma que la lectura anual en PostgreSQL ya no inicializa storage en request publico.
