The first observed token is paired with itself after start insertion · case 04

The first observed token is paired with itself after start insertion.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Given observations and bos, return adjacent pairs in [bos]+tokens, excluding any pair beyond the final observed target.

Why this case matters

A small deterministic token-stream contract makes next-token alignment errors inspectable.

One recorded failure
