🎯 Decision Tree

Fase Atual (MVP):

β”œβ”€ Database: Supabase Pro ($25/mth) βœ…
β”‚  └─ Alternative: PostgreSQL RDS ($15) - Mais ops
β”‚
β”œβ”€ Embeddings: Ollama Cloud ($5-15/mth) βœ…
β”‚  └─ Alternative: Gemini API ($20+) - Menor performance
β”‚
└─ Session Storage: Keep Firestore (fallback)
   └─ Reason: jΓ‘ estΓ‘ funcionando, migraΓ§Γ£o nΓ£o urgente

Fase Scale (Quando tiver trΓ‘fego):

β”œβ”€ Database: Keep Supabase (escala automΓ‘tico)
β”‚
β”œβ”€ Embeddings: Migrar para Compute Engine ($25) βœ…
β”‚  └─ Reason: economia 60% vs Ollama Cloud
β”‚
└─ Session Storage: Migrar para Supabase
   └─ Reason: single source of truth
