Keyed component instance reconciliation: Removed state pruning · case 02

Removed state pruning.

Member previewVariant 2 · 3 implementations · 70 checks per implementation

Case contract

A component instance is identified by sibling key plus component type. Reordering preserves its state, changing type remounts, removed keys lose state, and replacement cleanup happens before mount. Operation removed-state-pruning has the six explicit input/output oracles below.

Why this case matters

An offline client lifecycle model that isolates a state-management defect without DOM rendering or network services.

One recorded failure
