Your proposals all look good to me. One additional comment, below.

Yes, so I would suggest rephrasing the above as:

    This document defines a two-step convergence initiated by the router
    detecting a failure and advertising the topological changes in the
    IGP.  This introduces a delay between network-wide convergence and
    the convergence of the local router.
