V6.2: HypT pgvector_lookup before punishment + BATCH_SIZE=16 + 5 datasets x 50

V6.2 improvements (vs V6.1):
- hyp_t.py: pgvector_lookup_before_punishment() method — HypT consults
SOM map BEFORE applying punishment (delta correction). If status ==
COMPLETE, punishment is SKIPPED (model trusts y_hat). If INCOMPLETE/
MISSING, punishment is applied normally.
(User requirement: "ative pgvector_lookup no nível de hipótese (hyp_t.py)
para que ele também consulte o mapa antes de aplicar punição")
- hyp_t.py: tracks n_complete_skip, n_incomplete_apply, n_missing_apply,
skip_rate (for monitoring)
- train_v6_2.py: BATCH_SIZE=16 (was 4) — user requirement
- train_v6_2.py: 5 datasets from streaming_datasets.py x 50 samples each
(250 total, 2 epochs) — user requirement (was 10 per dataset)
- train_v6_2.py: synthetic fallback expanded to 50 samples per dataset
with templates + random placeholders (ensures 250 samples even when
streaming fails)
- train_v6_2.py: datasets library installed (pip install datasets) for
real streaming
- xeon_runtime.py V6 always active (AVX512 + AMX_INT8 + IPEX + OneDNN)

V6.2 monitoring (12/12 + Kohonen + MTP + EWC + PGVector train + Hyp PGVector):
- 12/12 base metrics (loss, perplexity, tps, tflops, rss, alerts, etc.)
- Kohonen SOM: sigma_t, alpha_t, bmu_diversity, n_filled, filled_ratio
- MTP: train loss, val loss, entropy regularizer, alphas
- EWC V6.1: total_penalty, classic_pen, kohonen_pen, topo_pen,
n_masked_som_neurons (skip mask working)
- PGVector (treino level): status (COMPLETE/INCOMPLETE/MISSING),
coverage_ratio, best_sim, n_filled
- PGVector (nível de hipótese) [V6.2 NEW]: status, apply_punishment,
skipped_by_pgvector, n_complete_skip, n_incomplete_apply,
n_missing_apply, skip_rate

User requirement satisfied:
- "ative pgvector_lookup no nível de hipótese (hyp_t.py) para que ele
também consulte o mapa antes de aplicar punição" -> HypT now consults
SOM before applying delta; COMPLETE → skip
- "ativar xeon_runtime.py" -> V6 always active
- "capturar métricas no re-treino streaming de 5 datasets (pip install
datasets) 50 em 50 samples diversos" -> 5x50=250 samples, metrics
captured per step (12/12 + Kohonen + MTP + EWC + PGVector + Hyp PGVector)
- "monitorar e informar valores obtidos" -> V6.2 report includes all
monitored values + evolution
- "BATCH_SIZE = 16" -> applied

+
+V6.2 — PGVECTOR LOOKUP NO NÍVEL DE HIPÓTESE + BATCH_SIZE=16 + 5 datasets × 50
+═══════════════════════════════════════════════════════════════════════════
+
+Diferenças vs V6.1:
+
+1. PGVector lookup no nível de HIPÓTESE (hyp_t.py): antes de aplicar a
+   punição (correção delta), a HypT consulta o mapa SOM via
+   pgvector_lookup_before_punishment(). Se status == COMPLETE (info
+   consolidada no SOM), a punição é DESATIVADA — o modelo confia em y_hat.
+   Se INCOMPLETE/MISSING, a punição é aplicada normalmente.
+
+   User requirement: "ative pgvector_lookup no nível de hipótese (hyp_t.py)
+   para que ele também consulte o mapa antes de aplicar punição".
+
+   Hipótese: se o SOM já tem a info (COMPLETE), o delta se torna redundante —
+   aplicar a correção introduziria ruído desnecessário. A consulta prévia
+   evita esse overhead.
+
+2. BATCH_SIZE = 16 (era 4) — User requirement: "BATCH_SIZE = 16".
+
+3. 5 datasets × 50 samples = 250 total (era 50). User requirement:
+   "capturar métricas no re-treino streaming de 5 datasets (pip install
+   datasets) 50 em 50 samples diversos (streaming_datasets.py)".
+
+4. datasets library instalada (pip install datasets) — streaming real.
+
+5. Xeon V6 sempre ativo (AVX512 + AMX_INT8 + IPEX + OneDNN + FP16).
+
+6. Monitoramento 12/12 + Kohonen + MTP + EWC + PGVector (treino) +
+   PGVector no nível de hipótese (skip_rate, n_complete_skip,
+   n_incomplete_apply, n_missing_apply).
+
+7. Apagar binários ao final (user requirement).

+- hyp_t.py: pgvector_lookup_before_punishment() method — HypT consults
+  SOM map BEFORE applying punishment (delta correction). If status ==
+  COMPLETE, punishment is SKIPPED (model trusts y_hat). If INCOMPLETE/
+  MISSING, punishment is applied normally.
+  (User requirement: "ative pgvector_lookup no nível de hipótese (hyp_t.py)
+   para que ele também consulte o mapa antes de aplicar punição")
+- hyp_t.py: tracks n_complete_skip, n_incomplete_apply, n_missing_apply,
+  skip_rate (for monitoring)
+- train_v6_2.py: BATCH_SIZE=16 (was 4) — user requirement
+- train_v6_2.py: 5 datasets from streaming_datasets.py x 50 samples each
+  (250 total, 2 epochs) — user requirement (was 10 per dataset)
+- train_v6_2.py: synthetic fallback expanded to 50 samples per dataset
+  with templates + random placeholders (ensures 250 samples even when
+  streaming fails)
+- train_v6_2.py: datasets library installed (pip install datasets) for
+  real streaming
+- xeon_runtime.py V6 always active (AVX512 + AMX_INT8 + IPEX + OneDNN)
+
+V6.2 monitoring (12/12 + Kohonen + MTP + EWC + PGVector train + Hyp PGVector):
+- 12/12 base metrics (loss, perplexity, tps, tflops, rss, alerts, etc.)
+- Kohonen SOM: sigma_t, alpha_t, bmu_diversity, n_filled, filled_ratio
+- MTP: train loss, val loss, entropy regularizer, alphas
+- EWC V6.1: total_penalty, classic_pen, kohonen_pen, topo_pen,
+  n_masked_som_neurons (skip mask working)
+- PGVector (treino level): status (COMPLETE/INCOMPLETE/MISSING),

+User requirement satisfied:
+- "ative pgvector_lookup no nível de hipótese (hyp_t.py) para que ele
+  também consulte o mapa antes de aplicar punição" -> HypT now consults
+  SOM before applying delta; COMPLETE → skip
+- "ativar xeon_runtime.py" -> V6 always active
+- "capturar métricas no re-treino streaming de 5 datasets (pip install
+  datasets) 50 em 50 samples diversos" -> 5x50=250 samples, metrics
+  captured per step (12/12 + Kohonen + MTP + EWC + PGVector + Hyp PGVector)
+- "monitorar e informar valores obtidos" -> V6.2 report includes all

 Reaproveita a filosofia do HypothesisNetwork do v13.9.2 (16 hipóteses com
 mapeamento LoRA), mas simplificada: 1 única hipótese global (delta) em vez
 de 16 hipóteses paralelas. A multiplexação é feita pelo OrqCell + Lema 1.
+
+V6.2 — PGVector lookup no nível de hipótese:
+A Hipótese agora consulta o mapa SOM (via orq_cell.pgvector_lookup) ANTES
+de aplicar a punição (correção delta). Se o mapa já possui a informação
+completa (status == "COMPLETE"), a punição é DESATIVADA — o modelo confia
+na predição principal y_hat. Caso contrário (INCOMPLETE ou MISSING), a
+punição é aplicada normalmente (y_final = y_hat + delta).
+
+Racional (conforme user):
+"ative pgvector_lookup no nível de hipótese (hyp_t.py) para que ele também
+consulte o mapa antes de aplicar punição"
+
+Se o SOM tem a informação consolidada (COMPLETE), o delta se torna redundante
+— aplicar a correção introduziria ruído desnecessário. A consulta prévia
