text-guard

What it is

text-guard.

Keeps the facts when a model rewrites text. It finds the spans a rewrite must not change — names, numbers, quotes, code, links, hashtags, and any the caller adds — then checks a rewrite against its original and lists every span it dropped or altered, and every number it made up. The extraction and the check are separate calls, so a caller can keep the spans across several rewrites instead of re-deriving them each time. Pair it with text-diff to show a person what changed without pretending the protected parts changed too.
