Hands-on validation labs for enterprise AI infrastructure. Keith Townsend's research, produced as audio by AI from his published lab records. Scoped real-hardware builds that test where decision authority actually holds.
Lab 007: The CPU exit is a batch lane, not a serving lane
Across 22 measured configurations, zero met the interactive latency bar; the Xeon lane delivers throughput or interactive latency, not both.

Lab 006: Put the judgment in the constraints, not the weights
Fine-tuning captured voice and bounded behavior, not judgment; one paragraph of standing positions in the system prompt beat two fine-tuning rounds.

Lab 005: Authority you reclaim is authority you run
A cloud-free serve path is provable end to end; every layer moved from Ceded to Retained is a decision you now own and a system you now operate.
Correction, September 28, 2026: this episode says the metal stayed Ceded, the lab's one cession. The lab's record has since been re-read under the instrument's Layer 0 rule, which places commodity NVIDIA hardware as Retained, so Layer 0 is now Retained before and after the migration and the lab has no cession at that layer. The five moves the episode describes are unchanged. The written lab carries the current placement.

Lab 004: You can’t automate a process you haven’t encoded
The control plane held where patterns were owned and encoded, and failed where the model became the author of correctness. The question is who may author the patterns and done-criteria.

Lab 003: The validator determines done, not the loop
About 5% of tasks benefit from same-tier repair; the control point is the deterministic validator plus escalation policy, not the loop.

Lab 002: Own the weights, or the platform owns you
For a custom model you own, cloud token pricing disappears and becomes a rented floor; against a floor the owned box wins, and the managed path takes the weights.

Lab 001: Borrow the vendor’s plumbing, not its judgment
The managed data plane is cheap and fast; the cost it hides is the chunking judgment it takes from you. Borrow the plumbing, keep your own chunking.
