+
+═══════════════════════════════════════════════════════════════════════════════
+V6.5-7ds — REAL STREAMING OF 7 DATASETS IN SEQUENCE + 864 NEURONS + W8A8 + TOOL_COORDINATOR
+═══════════════════════════════════════════════════════════════════════════════
+
+User requirements (V6.5-7ds, latest user message):
+    1. HF_TOKEN=hf_<REDACTED_TOKEN> (DELETED AFTER USE)
+    2. streaming_datasets.py + xeon_runtime.py ativo
+    3. Streaming até esgotar NESSA 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
+    4. Streaming com pausas para dar tempo de processar e salvar arquivos
+    5. Parar se o Armazenamento for crítico (threshold 90%)
+    6. Verificar métricas do modelo, raciocínio e capacidade de responder
+       (qualidade da resposta)
+    7. NÃO reduzir tempo e NÃO gerar dados sintéticos
+       (causam erro na interpretação do resultado)
+    8. Parar se o Armazenamento for crítico
+    9. Upload dos arquivos testados e os aprimorados corrigidos
+       (remover os antigos) — feito por upload_v6_5_7ds.py
+
+Mantido do V6.5-7ds (anterior):
+    - SOM_GRID: (6,6,6,4)=864 neurônios
+    - HIDDEN_DIM: 1024
+    - VOCAB_SIZE: 16384
+    - MTP_K: 6 (aumento MTP head size)
+    - V65_ENABLE_STREAMING=1 FORÇADO (real streaming, sem fallback sintético)
+    - SmoothQuantCompressor integrado ao KLS (W8A8 real dos pesos do SOM)
+    - tool_coordinator workers exercitados via execute_parallel()
+    - Limpeza agressiva de RAM e armazenamento
+    - Verificação de armazenamento a cada 5 steps (parar se > 90% cheio)
+    - gc.collect() + torch.cuda.empty_cache() a cada 10 steps
+
+Diferenças críticas vs train_v6_5_7ds.py:
+    - 7 datasets no lugar de 4 (3 novos PT-BR adicionados)
+    - 3 novos formatos de streaming em streaming_datasets.py:
+      * adalbertojunior/punctuation-ptbr (rows_api loader, config=punctuation-ptbr)
+      * iara-project/news-articles-ptbr-dataset (streaming parquet normal)
+      * manoela/noticias_ptbr (mirror do iara-project)
+    - SAMPLES_PER_DATASET_PHASE=50 (mantém budget por dataset)
+    - TOTAL_SAMPLES = 50 × 7 × 2 = 700 samples por epoch × 2 epochs = 1400
+    - INTER_BATCH_PAUSE_S=0.4 (levemente maior para dar mais tempo de salvar)
+    - INTER_DATASET_PAUSE_S=2.0 (maior entre datasets para limpar caches)
+    - Saídas renomeadas para v6_5_7ds_*.json

+═══════════════════════════════════════════════════════════════════════════════
+V6.5 FINAL — REAL STREAMING + 864 NEURONS + SMOOTHQUANT W8A8 + TOOL_COORDINATOR WORKERS
+═══════════════════════════════════════════════════════════════════════════════
+
+User requirements (V6.5 final, latest user message):
+    1. HF_TOKEN (provided by user via env var, deleted after use)
+    2. streaming_datasets.py + xeon_runtime.py ativo
+    3. Verificar toda a lógica e correções de bugs
+    4. Esgotar 4 datasets:
+       - dominguesm/restore-punctuation-ptbr-dataset
+       - carolina-c4ai/corpus-carolina
+       - CEIA-POSITIVO/ultrachat_br_clustred_balanced_v1
+       - dominguesm/Canarim-Instruct-PTBR-Dataset
+    5. Após verificar métricas do modelo, raciocínio e capacidade de responder
+       (qualidade da resposta)
+    6. V65_ENABLE_STREAMING=1 (REAL streaming, no synthetic fallback)
+    7. Integrar SmoothQuantCompressor ao KLS para compressão W8A8 REAL
+       dos pesos do SOM
+    8. Limpeza agressiva de memória RAM e de armazenamento
+    9. Aumentar SOM grid para (6,6,6,4)=864 neurônios
+   10. Aumentar MTP head size  (K=6 instead of K=4)
+   11. Reativar reasoning_engine's tool_coordinator workers
+   12. Não reduzir tempo e NÃO gerar dados sintéticos
+       (causam erro na interpretação do resultado)
+   13. Streaming com pausas para dar tempo de processar e salvar arquivos
+   14. Parar se o Armazenamento for crítico
+
+Diferenças críticas vs train_v6_5.py (anterior):
+    - SOM_GRID: (6,6,6,4)=864  ←  era (4,4,4,2)=128  (USER EXIGE 864)
+    - HIDDEN_DIM: 1024         ←  era 256
+    - VOCAB_SIZE: 16384        ←  era 4096
+    - MTP_K: 6                 ←  era 4  (aumento MTP head size)
+    - V65_ENABLE_STREAMING=1 FORÇADO (real streaming, sem fallback sintético)
+    - SmoothQuantCompressor integrado ao KLS (chamado em cada train_som_on_buffer)
+    - tool_coordinator workers exercitados via execute_parallel()
+    - Pausas de 0.3s entre batches para dar tempo de salvar arquivos
+    - Verificação de armazenamento a cada 5 steps (parar se > 90% cheio)
+    - gc.collect() + torch.cuda.empty_cache() a cada 10 steps
+    - 4 datasets (não 6): Canarim-Instruct-PTBR substitui OpenMath + Dexavator

+  3. Uploads the tested+improved files (current BiGRU_T_version tree).
+  4. Deletes OLD_FILES_TO_REMOVE from the HF repo via HfApi.delete_file.
+  5. Verifies critical V6.5-7ds files are present in repo.
+  6. Saves upload report to v6_5_7ds_upload_report.json.
+
+After successful upload, the HF_TOKEN env var MUST be deleted by the caller.
