A direct memory page mapped at one guest address now lives in private MEM_WRITE_WATCH memory at that address, and its writes are collected with GetWriteWatch like flexible memory: no fault is raised. A page mapped at a second address moves its whole resident run into the section, behind a read-only fence while it is copied, and every address becomes a view of it, tracked by write protection. Unmapped resident pages that are not blank are kept in a private reservation until they are mapped again, not in the section. Ported onto main's 4 KiB subpage tracking of shared views: resident runs keep a per-page collected bit and enter the fresh ranges, so Fresh and Armed collections select them like shared views; a demoted run carries its collected bits into the views and reports every page once. MapAlias throws through refuse() when a resident run extends outside the aliased range, and the caller keeps main's fallback.
