Invalidating an empty-header variant also removes the absent-header variant · case 05

Invalidating an empty-header variant also removes the absent-header variant.

Member previewVariant 5 · 3 implementations · 4 checks per implementation

Case contract

Entries are [variant-ID,normalized request-header mapping]. Remove entries matching every selected header in both presence and exact string value; preserve all other variants and their order. Empty selected names match every variant.

Why this case matters

A deterministic cache state transformation. Inputs are copied or treated as immutable; no remote storage, real clock, or concurrent interleaving is simulated.

One recorded failure
