Layer2C Labs https://labs.layer2c.com 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. en-us Keith Townsend Keith Townsend keith@advbench.com false Thu, 03 Sep 2026 19:55:27 GMT Lab 006: Put the judgment in the constraints, not the weights https://labs.layer2c.com/labs/constraints-not-weights https://labs.layer2c.com/labs/constraints-not-weights#audio Thu, 03 Sep 2026 19:55:27 GMT Fine-tuning captured voice and bounded behavior, not judgment; one paragraph of standing positions in the system prompt beat two fine-tuning rounds. 0:23:24 Keith Townsend false Lab 005: Authority you reclaim is authority you run https://labs.layer2c.com/labs/vctoa-to-spark https://labs.layer2c.com/labs/vctoa-to-spark#audio Mon, 24 Aug 2026 05:00:00 GMT 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. 0:09:33 Keith Townsend false Lab 004: You can’t automate a process you haven’t encoded https://labs.layer2c.com/labs/migration-control-plane https://labs.layer2c.com/labs/migration-control-plane#audio Thu, 20 Aug 2026 05:00:00 GMT 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. 0:09:57 Keith Townsend false Lab 003: The validator determines done, not the loop https://labs.layer2c.com/labs/loop-control https://labs.layer2c.com/labs/loop-control#audio Mon, 17 Aug 2026 05:00:00 GMT About 5% of tasks benefit from same-tier repair; the control point is the deterministic validator plus escalation policy, not the loop. 0:08:17 Keith Townsend false Lab 002: Own the weights, or the platform owns you https://labs.layer2c.com/labs/fine-tune-economics https://labs.layer2c.com/labs/fine-tune-economics#audio Thu, 13 Aug 2026 05:00:00 GMT 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. 0:09:18 Keith Townsend false Lab 001: Borrow the vendor’s plumbing, not its judgment https://labs.layer2c.com/labs/spark-s3vectors https://labs.layer2c.com/labs/spark-s3vectors#audio Wed, 12 Aug 2026 05:00:00 GMT 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. 0:10:58 Keith Townsend false
