Re-auditing the default frame from reconciled main surfaced three defects none of the three recent Bevy sessions could see alone: the focused-machine INFO flag overprinted the breathing NOW mark in the shared upper-right corner; the hover-bar's children spawned and toggled with an explicit Visibility::Visible that overrode the hidden root, painting stray TAP / UNTAP / TAKE rows at the unplaced origin; and every screenshot scenario except hover-menu read the live OS pointer, letting the operator's resting mouse grow a device bar inside evidence frames. The NOW mark now takes the mirrored upper-left corner, hover-bar children are Visibility::Inherited so the hidden root hides the tree, and any staged screenshot ignores the pointer (the per-shot reticule-only flag is retired as redundant). Defense: implements clinical-frame.md 'one focused machine is one composition' via its 2026-07-19 joint-frame repair note - one fact per corner of the anchor, no stray chrome, and deterministic capture evidence. Verified by ./tools/check.sh --frontend and a re-captured flat/hover-menu pair recorded in wiki/log/2026-07-19-bevy-joint-frame-repair.md.
