Research direction

The issue does not name files, tests, or an entry point. Start by locating the signed-tableau definitions and tag handling in the TeX textbook sources, then confirm that the new tag removes T/F signs and that branches close on A and \lnot A.

Written by the indexing model from the issue text.

Description

Add a tag that turns signed into unsigned tableaux (no T/F signs, tableau closes when A and \lnot A is on branch).

Signed tableaux can directly be generalized to many-valued logic, but unsigned tableaux are a bit simpler and more familiar from intro courses.
