+═══════════════════════════════════════════════════════════════════════════════
+V6.5-attn — ATTENTION ATIVO + 100 SAMPLES/BATCH + META ≥5000 + 7 DATASETS
+═══════════════════════════════════════════════════════════════════════════════
+
+User requirements (latest):
+    1. limpar ambiente virtual; usar última versão
+    2. verificar se o mecanismo de atenção está ativo e acessado logicamente funcional
+    3. HF_TOKEN (apagada após uso)
+    4. usar streaming_datasets.py e ativar xeon_runtime.py
+    5. streaming de 100 em 100 samples até esgotar nesta sequência (7 datasets):
+       1. dominguesm/restore-punctuation-ptbr-dataset
+       2. carolina-c4ai/corpus-carolina
+       3. CEIA-POSITIVO/ultrachat_br_clustred_balanced_v1
+       4. dominguesm/Canarim-Instruct-PTBR-Dataset
+       5. adalbertojunior/punctuation-ptbr
+       6. iara-project/news-articles-ptbr-dataset
+       7. manoela/noticias_ptbr
+    6. streaming com pausas para dar tempo de processar e salvar arquivos
+    7. parar se o Armazenamento for crítico
+    8. verificar métricas do modelo, raciocínio e capacidade de responder
+       (qualidade da resposta)
+    9. NÃO reduzir tempo e NÃO gerar dados sintéticos
+   10. meta mínima 5000 samples ou mais
+
+Diferenças críticas vs train_v6_5_7ds.py:
+    - NOVO: MultiHeadAttention integrado ao text_to_4d_vector (V6.5-attn)
+    - NOVO: get_attention_metrics() exposto em get_state_metrics()
+    - NOVO: Check #11 = attention_logic_functional (n_calls>0, n_errors==0,
+      last_attn_activated=True)
+    - STREAM_BATCH_SIZE=100 (era 50) — user requirement "de 100 em 100 samples"
+    - N_PHASES=8 (era 2) → 100 × 7 × 8 = 5600 samples (meta ≥5000 OK)
+    - EPOCHS=1 (cada phase = 1 epoch; 8 phases = 8 passes pelo streaming)
+    - META_MINIMA_SAMPLES=5000 (user requirement: "meta mínima 5000 samples ou mais")
+    - Saídas em v6_5_7ds_attn_*.json (não sobrescreve v6_5_7ds_*.json)
