Weight system expansion: param layout [20] → [22] tensors with
NUM_WEIGHT_TENSORS constant. Tensors 20-21 (w_bn, b_bn) hold temporal
causal bottleneck weights. Size 0 when bottleneck_dim=0 (backward
compatible — existing models load without changes).
Config: bottleneck_dim field added to DQNHyperparameters, GpuDqnTrainConfig,
TOML [generalization] section, and training profile. Default: 0 (disabled).
Set to 2 for maximum information compression.
Crown Jewels plan (Tasks 31-34):
- Gem (#31): 2D Temporal Causal Bottleneck (architecture defense)
- Pearl (#32): Gradient Vaccine (optimization defense)
- King (#33): Adversarial Self-Play with Past Self (strategic defense)
- Emperor (#34): Causal Intervention Training (epistemic defense)
Four layers of defense making memorization impossible at every level.
