* Compare, Restrict Editing and AutoCorrect Options dialogs (#412) - Compare / Combine Documents dialog: original (this document or a file) and revised document, label changes with, More >> comparison settings, word or character level, show changes in. review.compare honours case changes, white space, formatting (tracked formatting changes), tables (compared and kept, no longer dropped) and character level; the LCS no longer drops text past its size cap. Unsupported settings are accepted and reported. - Restrict Editing pane: formatting restrictions (locked styles, w:formatting), editing restrictions, exceptions for everyone (w:permStart/permEnd), Start Enforcing Protection with an optional password (SHA-512, salt, spin count 100000; ECMA-376 §17.15.1.29) and Stop Protection. Enforced in Session::run: outside the exceptions nothing may change; undo can't lift protection; passwords never land in Repeat/macros. DOCX round trip of protection, hash attributes, locked styles and ranges. - AutoCorrect Options dialog: replacement list (add/replace/delete, built-in entries too), capitalization options with exceptions, AutoFormat As You Type switches, Math AutoCorrect list. Saved per user in ui.json; damaged values read as defaults. Names of days are capitalised.

A wrong password is rejected; the form no longer unlocks with any password. - Unsupported or damaged hashes (MD2/MD4/MD5 and other SIDs, w:algIdExt, unknown algorithmName, spin counts above 10,000,000, bad base64) refuse with "This password type isn't supported" and the protection stays on. A protection without a hash still stops without a password. - Known-answer tests: the specification's "Example" key 0x64CEED7E and an independently computed SHA-1 hash; pane message in all 9 catalogs.
