EvalTier

Defined in: packages/engine/src/engine/ThreeTierEvaluator.ts:40

How much work a line’s evaluation required.

The tiers exist because most lines in a document have not changed. A line that is clean and cached costs far less than one being compiled fresh, and knowing which happened is how a slow document gets diagnosed.
