A graphite pencil drawing shows two tiny suited figures standing beside a massive upright binder secured by a crossed red string.

Cost

Ordinal & Vector

Cost is a vector, never one number: hours, money, capability, capacity, attention, each with its own magnitude. Cost is ordinal and price is cardinal, and only cost survives being said to another person. Stating cost while it arrives is what keeps a choice conscious.

Gradient

Axis & Latent

Value is the axis. The gradient is computed from it and carries no judgment: descent is the path of least resistance, and its mirror above the baseline is the latent potential. What a system routes around is where its unprocessed material sits.

Small figures stand before a giant rook carved from thousands of delicate matchsticks rising abruptly from a flat grey ground.

Delta

Feedback & Validation

Did it move. Feedback lives in data that needs no third party; validation is the moment a thing leaves the head. The shortcut is invariant, the same answer whatever enters it, and invariance is the tell.

Six fields, each writing its own terms

The terms are written where they belong. Each field holds three desks, and every entry a desk writes raises the terms it uses, each term given a meaning, a mechanism and the places it appears. The record on these pages stays first person and hand made; the fields grow the nomenclature.
