The flagship · five parts
The Spread
A full stocker cattle decision model: price slide, cost of gain, breakeven, and a hedge signal. Then a twelve-turn season with 500 head across five lots, sickness and slow-gain events, and a decision ledger that shows what each call cost you.
Input provenance
Every input tagged · The Spread
The model surfaces and suggests; it does not decide. It shows the economic consequences of the available choices.
The portfolio
Same engine, other domains
Each one puts you inside a situation, takes your decisions turn by turn, and scores what they cost. The domain changes; the method does not.

Forensic analysisMethod
The honest version
Every input in every model carries a tag: Live pulled from a named source, Manual entered by the operator, Estimate derived from other inputs, Not linked no feed exists and the model says so.
Most modeling hides this. Showing it is the point — a model you can't audit is a slide with arithmetic on it.
These aren't products for sale. They're proofs of capability. The differentiator is forensic judgement — CPA, CFE, Lean Six Sigma — not the software.
