The Library stores text.strip() while a run keeps its exact raw text. The history window, run detail scope id, newest pair run and prompt hints now compare the raw text's stored form (one rule, utils/hashing.py, mirrored in SQLite with the same code points). Hints also keep matching the exact raw text, so older rows that kept outer whitespace stay hinted and protected.
