"""test_hyp_t_synergy.py — Teste focal do novo hyp_t.py sinérgico (V6.5-V3).
Valida que o módulo aprimorado `SynergyHypothesisEnsemble` (em
`src/bigru_t/model/hyp_t.py`) está funcionando corretamente com:
1. Sinergia matemática ativa (4 pilares: diversidade, cooperação,
competição, ortogonalidade).
2. Constantes canônicas respeitadas (N=16, MAX=32, hidden=256).
3. Compatibilidade reversa com `HypT` (V6.4 legado).
4. Forward estável (sem NaN/Inf) sob diferentes batch sizes.
5. Treino simples (10 steps Adam) converge sem explodir gradiente.
6. Gating aprende distribuição não-uniforme após treino.
7. OOM-guard: lida com batches grandes sem estourar memória.
8. Estado salvável e carregável (state_dict round-trip).
User requirement: "ao concluir (testes de FASE2) fazer o upload de hyp_t.py".
Este teste é uma pré-condição para o upload — se algum check falha, o
módulo não deve ser enviado para o HF.
