Hyperlink destinations lose their fragment identity · case 05

Hyperlink destinations lose their fragment identity.

Member previewVariant 5 · 3 implementations · 6 checks per implementation

Case contract

Input [text_length,links,offset] where links [id,start,end,url,enabled]. Admit only nonempty URL, enabled and nonempty interval after clamping. Sort by start then shorter interval then input order; dedupe IDs after sorting. Query offset resolves the first matching half-open span, or None. Return [ordered descriptors,hit_id]. URLs remain exact including fragments; IDs are retained even when URL is shared.

Why this case matters

Offline accessibility bridge model with explicit policy; useful for testing semantic API adapters independently of browser implementations.

Sample boundary fixture

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