V6.5-attn-v3: CORREÇÃO MATEMÁTICA do predict() — rótulos dinâmicos extraídos do label_registry (substitui 'gato'/'cachorro' fixos). NOVO: punish_during_inference() — mirror do protocolo de punição do treinamento (1ª → activate_hypothesis, 2ª → set_ewc_reference). META ≥6000 samples, attention ACTIVE_AND_FUNCTIONAL, SmoothQuant W8A8, 864 neurons, MTP K=6, 3 perguntas reais sem ajuda (Luva de Pedreiro Távila, Lula reserva valor, Amazonas força-tarefa vítimas) + punição na inferência via camada de hipótese. Removed legacy v2 reports/scripts (superseded by v3).

+"""train_v6_5_7ds.py — V6.5-7ds (7 datasets streaming, 864 neurons, SmoothQuant W8A8, tool_coordinator workers reactivated).
+
+═══════════════════════════════════════════════════════════════════════════════
+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-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)

+This script:
+  1. Pre-upload safety: scrub HF_TOKEN from all scripts/*.py via regex.
+  2. Defines OLD_FILES_TO_REMOVE — legacy v3/v4/v5/v6_1/v6_2/v6_3/v6_progressive
+     reports and scripts, plus old v6_5_* files (superseded by v6_5_7ds_*).
+  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.

+V6.5 — ATIVAR VQ-VAE-2 NO PIPELINE DE COMPRESSÃO + INTEGRAR REASONING_ENGINE
+
+Implementação CANÔNICA do Sistema de Aprendizado Kohonen 4D fornecida pelo
+usuário, com análise matemática formal e 2 correções de bugs críticos.
+
+============================================================================
+ANÁLISE MATEMÁTICA FORMAL
+============================================================================
+
+1) text_to_4d_vector(text, ..., time_step, T_max):
+   -----------------------------------------------
+   Tokenização BBPE: ids = BBPE_encode(text, max_len=seq_len) → [seq_len]
+   Embedding:        E = Embedding(ids)            → [seq_len, D]
+   PE sinusoidal:    PE = sin/cos(pos · exp(-2k·log(10000)/D))
+   Fusão:            F = E + PE                    → [seq_len, D]
+   Centralização:    F_c = F - mean(F, dim=0)      → [seq_len, D]
+   SVD:              F_c = U · S · V^T              (V: [D, D] ortogonal)
+   Projeção 3D:      coords_3d = F_c · V[:3,:]^T    → [seq_len, 3]
+   Centróide:        xyz = mean(coords_3d, dim=0)   → [3]
+   Coordenada temporal: w = time_step / T_max       ∈ [0, 1] (LINEAR)
+   Saída:            vec_4d = [x, y, z, w]          → [4]
+
+   Nota (V6.4): w é LINEAR no tempo (diferente de sigmoid(||xyz||)).
+   Isto permite que o SOM organize neurônios ao longo do eixo temporal,
+   capturando a sequência absoluta de amostras — útil para deteção
+   de drift e consolidação incremental (EWC).
+
+2) KohonenSOM4D:
+   --------------
+   Grid:    W ∈ ℝ^(I×J×K×L×4), default (6,6,6,4) = 864 neurônios
+   BMU:     bmu = argmin_{i,j,k,l} ||W[i,j,k,l] - x||²    (Euclidiana ℝ⁴)
+   Vizinhança (Gaussiana 4D):
+            Λ(d, σ) = exp(-d² / (2σ²))
+            d² = Δi² + Δj² + Δk² + Δl²  (distância quadrada no grid 4D)
+   Update (Kohonen):
+            ΔW = α · Λ · (x - W)        (competitivo + cooperativo)
+   Decaimento:
+            σ_t = σ₀ · exp(-t/1000)     (vizinhança encolhe rápido)
+            α_t = α₀ · exp(-t/2000)     (LR decai mais lento)
+   EWC (apenas na 4ª dimensão w):
+            L_ewc = (λ/2) · Σ F_i · (W_w,i - W*_w,i)²
+            ∂L_ewc/∂W_w = λ · F · (W_w - W*_w)
+            Aplicado como: update[..., 3] -= λ · F · (W_w - W*_w)
+   Fisher (aproximação como erro quadrado):
+            F_i = mean((x_w - W_w,i)²)  sobre samples pré-punição
+            Acumulado apenas quando:
+              (a) punishment_count == 0
+              (b) old_weights_w is None  (ainda não consolidado)
+              (c) Λ > 0.1                (neurônios próximos ao BMU)
+
+3) HypothesisClassifier:
+   ----------------------
+   8 camadas FC: [in → 512 → 256 → 128 → 64 → 32 → 16 → 8] + ReLU
+   Output:      8 → 1 (logit)
+   Loss:        BCEWithLogitsLoss
+   Optimizer:   Adam, lr=0.001
+   Epochs:      50 (sobre o buffer atual)
+   Input:       vetor de ativação SOM = distâncias ao grid flatten
+                (864-dim para grid (6,6,6,4))
+
+4) Punishment Protocol:
+   ---------------------
+   Histograma:     bucketiza vec_4d[dim_choice] (default 'y', idx=1)
+   check_training_start:
+                    max(histogram.values()) >= N_start → ready
+   Avaliação:      acc = correct / len(buffer)  (correct = pred==label)
+   Se acc < 1.0:
+     punishment_count += 1
+     success_count = 0
+     Se punishment_count == 1: activate_hypothesis() (treina classifier)
+     Se punishment_count == 2:
+       set_ewc_reference() (consolida w via Fisher)
+       required_new_samples = success_count * N  (ou N se success==0)
+       reset: training_ready=False, punishment=0, success=0,
+              histogram cleared, buffers cleared
+   Se acc == 1.0:
+     punishment_count = 0
+     success_count += 1
+
+5) PGVector NÃO É MAIS NECESSÁRIO (V6.4):
+   ---------------------------------------
+   O método find_bmu realiza a busca nearest-neighbor sobre o grid 4D,
+   substituindo qualquer lookup pgvector externo. O SOM interno já
+   armazena todo o conhecimento como pesos 4D, e find_bmu retorna o
+   neurônio mais próximo em O(I·J·K·L) — equivalente a uma busca
+   pgvector com indexação flat.
+   Consequentemente, hyp_t.py NÃO consulta mais pgvector — a decisão
+   de aplicar punição é delegada ao KohonenLearningSystem.
+
+============================================================================
+BUGS CORRIGIDOS (V6.3 → mantidos em V6.4)
+============================================================================
+
+BUG 1 (find_bmu): V6.3 corrigiu return prematuro com Ellipsis.
+   V6.4: código do usuário já está limpo (unravel manual sem return
+   prematuro). Mantido as-is.
+
+BUG 2 (activate_hypothesis): backward tentava retropropagar através
+   do embedding (via buffer_4d). Causava RuntimeError "Trying to
+   backward through the graph a second time".
+   FIX V6.4: detach+clone nos tensores de entrada do classifier,
+   e cálculo do vetor de ativação SOM dentro de torch.no_grad().
+   O classifier treina apenas sobre seus próprios pesos (8 FC layers).
+
+============================================================================
+V6.5 — VQ-VAE-2 NO PIPELINE DE COMPRESSÃO
+============================================================================
+User requirement: "ativar efetivamente o VQ-VAE-2 no pipeline de compressão"
+
+Integração: o KohonenLearningSystem agora possui um `vqvae2_compressor`
+opcional (HierarchicalVQVAE2 do módulo vqvae2_hierarchical_flexnet.py).
+Quando ativado:
+
+1. Após `train_som_on_buffer()`, o buffer_4d (B, 4) é passado ao VQ-VAE-2
+   como entrada. O encoder mapeia (B, 4) -> z_e (B, code_dim).
+2. O VQ hierárquico produz:
+   - z_q_top: estrutura global do batch (codebook K_top)
+   - z_q_bot: detalhes residuais (codebook K_bot)
+3. O decoder reconstrói z_recon (B, 4) a partir de z_q_combined.
+4. A loss do VQ-VAE-2 (commitment + recon) é computada e retornada
+   para monitoramento (não adicionada à loss do SOM — são objetivos
+   ortogonais: SOM aprende topologia, VQ-VAE-2 aprende compressão).
+5. Códigos top/bottom podem ser usados como representação compacta
+   do estado do SOM para armazenamento/transferência.
+
+Benefícios:
+- Compressão neural do espaço 4D do SOM (4 -> code_dim -> 2 códigos)
+- Codebook compartilhado entre batches (aprendizado incremental)
+- Dead code restart evita colapso do codebook
+- Goose VQ (Gumbel-softmax) força uso uniforme do codebook
+
+============================================================================
+V6.5 — REASONING_ENGINE INTEGRADO
+============================================================================
+User requirement: "integrar reasoning_engine ao KohonenLearningSystem"
+
+Integração: o KohonenLearningSystem agora possui um `reasoning_engine`
+opcional (ReasoningEngine do módulo reasoning_engine.py). Quando ativado:
+
+1. Após `predict()`, o resultado da predição é passado ao reasoning_engine
+   que gera uma sequência de tags <think>, <plan>, <decompose>,
+   <execute>, <monitor>, <predict>, <adjust>, <answer>.
+2. O reasoning_engine pode usar ferramentas registradas (tool_agent)
+   para consultas externas (ex: calculator, knowledge_base).
+3. O streaming de raciocínio é compatível com Ollama/LangChain/vLLM
+   via tags padrão.
+4. Para predições do SOM, o reasoning_engine pode explicar o porquê
+   do BMU ter sido escolhido (análise de distâncias).
+
+Métodos adicionados:
+- reason_about(query): retorna generator com streaming de raciocínio
+- reason_sync(query): retorna string completa com todas as tags
+- get_reasoning_stats(): retorna estatísticas do reasoning_engine
