Formal effects pipeline for evaluation (ticket 603).

An Effect is an explicit, inspectable side-effect produced by formula evaluation. Effects are planned deterministically from (computed_value, workbook_state) and applied sequentially.

This separation enables:

  • Parallel computation with sequential apply
  • ChangeLog integration at the effect layer
  • Deterministic replay without re-evaluation

Enums§

Effect
An explicit, inspectable side-effect produced by formula evaluation.

Type Aliases§

EffectBatch
A batch of effects from evaluating a single layer. Each entry pairs a vertex with its planned effects.
