Why removing webNavigation broke Drive and the anime hosts, the verified frame
layout of the live KODIK page, each defect that was fixed on the way from tab
selection to playback control, and how the frame list is reconstructed without
the permission.
Also records the one defect still open: an elected frame that the player has
since torn down is never released, because the guarded refresh reports
"unchanged" when no video is reachable and adoption has already set
hasVideo, so nothing moves the target back.
