The Matrix Primitive
Comparisons
Two scenarios, one form. Each column is an isolated instance of the same tool. The delta bar subtracts the live variables and picks a winner.
No A/B switching, no "run it again with different numbers." Both paths visible at once.
Two Geo Arbitrage forms side-by-side. Price the stay path against the move path. Delta bar picks a winner on monthly gain.
Minimum Viable Rate in two modes — salaried offer vs. contract rate. The honest hourly that matches the W-2 take-home.
Two Gig-Net Floors side-by-side — DoorDash mileage profile vs. Uber routes. Real hourly after IRS depreciation.
How the matrix primitive works
Each column is a namespaced instance of the same tool. They write to separate keys
(field__a and
field__b) in the shared session
context. The delta bar subscribes to both and re-renders live. No server, no storage off-device.
