Field to Decision. Five systems, four decades, one discipline.

Applied data science that starts in field conditions and ends in decisions executives, regulators, and clinicians act on. Traffic sensors, dispensing cabinets, radioactive cargo, biomedical text. Each story closes with what it looks like in the 2026 stack, because the point of the past is what it builds next.

STORY 01
The Map That Settled $300M
Lawyers denied it for three years. A zip-code map ended it in 24 hours. $300M+ recovered across 27 mapped markets.
STORY 02
Racing the Half-Life
F-18 decays in 110 minutes, so the physics designed the network. 50K to 3M+ scans a year; 400+ radiopharmacies still run it.
STORY 03
The Human Stays in the Loop
Four eras from a tethered balloon to LLM production lines. 96% ML accuracy across 300+ hospitals; FDA signatory preserved.
STORY 04
From Clickers to Cell Signals
An industry measured with street-corner clickers for 70 years. Then measurement became a product, and the product became the standard.
STORY 05
Silent Failures
The contaminated doses passed every checkpoint. 47× over the limit, all gates green. Zero production AI failures in 8 years since.
APPENDIX
Data to LLM: The 2026 Stack, Hands-On
The working pipeline, the last 12 months of change, and a 2023 build the industry caught up to.
DEMO
Airport Energy, Worked Live
The RS&H energy-demand problem, run end to end against real data.
ONE PAGE
Read the complete set
All five stories plus the appendix in a single scrollable page. About fifteen minutes end to end.
The set

Five stories, one appendix, in reading order.

01
The Map
Evidence in the data's own coordinates.
02
Half-Life
A national network built against decay physics.
03
The Loop
Four eras of automated detection with human authority.
04
Clickers
Measurement productized and certified as the standard.
05
Silent Failures
Verification designed where gates report green.
A
The Stack
The same discipline in the August 2026 toolchain.

Some stories draw on reconstruction and first-person material where the underlying records are private. Figures are cited to SEC filings, NRC notices, and trade press where public records exist.
