Client route-state projection: First value precedence · case 05

First value precedence.

Member previewVariant 5 · 3 implementations · 60 checks per implementation

Case contract

This route-state adapter models already-decoded query pairs. Repeated pairs and insertion order remain significant, first occurrence is used by single-value readers, explicit empty values override defaults, and fragment absence differs from empty. Operation first-value-precedence 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
