Correct architecture and AD-21 to the existing transaction: normal non-login world frames participate, a walk contributes its exact landscape set, null-root completes an empty set without reconstruction, and login/portal-space retain no completed view.
Record the owner-authorized exception as in progress. Historical dirty-base artifacts remain preserved but clean exact-commit hermetic and InstalledDat evidence plus narrow review are still pending; no counts or hashes are invented.
Scope proof: no src or tests diff relative to b7a7eb9e2; git diff --check clean. No lanes or graphical client run by this commit.
