Each dictionary batch replaces the unified value domain · case 05

Each dictionary batch replaces the unified value domain.

Member previewVariant 5 · 3 implementations · 7 checks per implementation

Case contract

Unify dictionaries from ordered batches by first encountered dictionary value, including unused values. Rewrite valid local indices into the unified domain, retaining null lanes and batch boundaries; duplicate dictionary values share one code.

Why this case matters

A bounded deterministic data engine model makes representation and changelog faults reproducible.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
overlapping domains	`[[7, 5], [[1, 0], [1, 0]]]`	`[[5, 6, 7], [[1, 0], [0, 2]]]`	Failed
