The finale states the honesty boundary: this is one exact forward pass with a given kernel. Training and any classifier softmax are outside this book.
highlighted = computed this step
What stayed exact
The convolution sums, ReLU clamp, and max-pool selection are all exact integer operations. The final pooled value in this toy pass is 9.
conv→ReLU→pool=9
What is outside this surface
The kernel is given, not fit here. If a classifier head followed this pass, its softmax would be a NAMED boundary, not an exact decimal computed in this book.
kernel given; softmax named if a head is added
What a convnet pass is and is not
This is one exact forward pass through convolution, ReLU, and max-pool. It is NOT training, NOT learning, and NOT a claim about a full classifier.
