Labs
Technical labs for observability, debug infrastructure, and compute-system thinking.
Public, interactive demos. No employer-confidential detail, just the underlying ideas, made inspectable.

TAP controller explorer
Drive the IEEE 1149.1 TAP one TCK at a time, or run a guided DR scan. The state graph, scan register, history, and synchronized TCK/TMS/TDI/TDO trace show how hidden silicon state becomes serial evidence.
Try this
- 01Run the guided DR-scan path
- 02Step TMS through a branch
- 03Scrub the synchronized waveform

Fault injection vs. observability
Choose a fault and replay the same transaction through instrumented and blind pipelines. The first divergent probe exposes where detection latency and search space disappear: the practical value of observability.
Try this
- 01Choose a deterministic fault
- 02Compare instrumented and blind lanes
- 03Replay the detection timeline

Cost of Usable Intelligence
Move latency and reliability, or load a scenario preset. The plot connects retries, staleness, uncertainty, and baseline cost so the operating point reflects usable output rather than raw token price.
Try this
- 01Compare scenario presets
- 02Move latency and reliability
- 03Copy a reproducible scenario URL

Open-source stack
Purpose-built engines, one visual language.
Each dependency has one job: simulation truth, graph layout, timing, plotting, or motion. Heavy engines are loaded only as their lab approaches the viewport.
