Classified as not security-relevant.
Triage note: SaferCPP migration: replaces document().updateLayout*() with protect(document())->..., removes SUPPRESS_UNCOUNTED_ARG/SUPPRESS_UNRETAINED_ARG false-positive suppressions, adds NOESCAPE. No identified bug; pure smart-pointer/annotation migration across editing/ and Modules/.
