01// = — Definition

Defines. Names the essence. States the thesis.

Cognitive question answered: "What is it?"
One line = one semantic unit. The Equals operator tells the reader — before they read the content — that this line answers: What is it?
02// When to use it

Use = when you are answering 'what is this thing?'. Goals, contexts, identities, core definitions — anything that establishes what something IS before you explain what to do with it.

When NOT to use it:
Don't use = for opinions, actions, or conclusions. = is a declaration of essence, not a step or judgment.
03// Live Examples
Goal definition
=CLN — plain-text semantic notation for structured thinking
=purpose — make structure of thought visible and typed
=not Markdown — no rendering required — cognitive tool, not display format
Project context
=project — migration from PostgreSQL to PlanetScale
=scope — auth service only — not billing
=deadline — 2026-03-01
Concept distillation
=compound interest — earning returns on your previous returns
=core mechanic — growth is exponential — not linear
=key variable — time — most undervalued input
04// Operator Pairs

Operators don't work in isolation — they form semantic pairs that together convey full cognitive structure:

→= defines the thing · → states what it produces
!= says what it is · ! says what can go wrong with it
.= provides context · . gives the action steps that follow
