Layer2C Labs

What's ready, what's not, where the boundary lives.

Hands-on technical validation across the 4+1 AI Infrastructure framework. A lab takes a slice of the stack, a single layer, a combination, or the whole model, builds it for real, and publishes where the seams actually fall, scored against the 4+1 model and DAPM.

Borrow the vendor’s plumbing, not its judgment

I built a retrieval pipeline across a public-cloud data plane and a local box to map where authority actually sits across the 4+1 stack. The economics were the boring part: eighty-four cents, the cloud faster. The finding worth keeping is what the managed path quietly decides for you, and the two questions the lab now knows to ask.
