Renderer reset erases already emitted speech · case 05

The announcement trace violates the stated speech-markup contract.

Member previewVariant 5 · 3 implementations · 7 checks per implementation

Case contract

Bounded token renderer has independent language and emphasis stacks. Text emits [language,emphasis,text]. Push/pop scopes restore prior values; unmatched pops are ignored. Spell emits characters separated by spaces; digits uses fixed English digit words preserving zeros. Pause emits [pause,nonnegative duration] without text. Mark emits named bookmark and current spoken-text count. Break emits newline. Reset restores base en/normal without deleting output. Empty text emits nothing.

Why this case matters

Deterministic controlled model of assistive announcement delivery.
