Direct baselines enable underwater acoustic transponders to measure distances directly between seafloor nodes, bypassing surface vessels to accelerate subsea positioning.

In deepwater operations, traditional acoustic positioning relies on surface vessels to ping and calibrate seafloor arrays, a process vulnerable to weather delays and high ship-charter costs. Direct baseline technology changes this dynamic by enabling intelligent transponders, such as Sonardyne's Compatt series, to measure distances directly between one another on the seabed. By utilizing acoustic telemetry to calculate these baseline vectors locally, operators can calibrate complex subsea networks in a fraction of the time, achieving centimeter-level positioning accuracy for critical offshore construction and geodetic monitoring.

## Recent Public Talks and Demos

### [Cognitive Cell: Building a Route-Select-Render Control Layer for Workflow AI](https://columbus.aitinkerers.org/talks/rsvp_o1YZyZ3Z09I)

I built Cognitive Cell, a public Python package and HTTP sidecar that sits in front of an LLM and decides whether an input should be recorded, clarified, analyzed, planned, answered directly, or escalated. The accepted v9 stack is router-v4 → selector-v5 → finalizer-v9. I will show the live package, CLI, HTTP sidecar, architecture, traces, evaluation files, and the messy journey from a research prototype to a PyPI package. Live demo elements: - Python package: pip install "cognitive-cell[server]" - CLI: cognitive-cell --event-json ... - HTTP sidecar: cognitive_cell.server.app - /health endpoint - /v1/sidecar endpoint - trace output - evaluation CSV/JSONL artifacts - ablation results
