Every opener ends the span first, so a tag fired mid-drain no longer hijacks the
switch's point. One stated criterion governs both lane sites; no-op actions discard.
Flag writes are silent from a timer, so a block around a reapply or the reconcile
repair could only manufacture a point. The real switch's span is unchanged.
applyMode now returns with its undo block open; the reclaimer closes it when the drain
settles. A transport deferral or a tab switch ends it early -- two points, never a leak.
Fixes a hidden-parent solo replay that could silence the mix. Also closes the N-mode segment silent no-op, amends the invariant comment, trims view.cpp under 600 lines, hedges two SDK inferences, drops a dead null-check.
Solo is cached, cleared and replayed per mode on a real switch only; the switch is refused visibly while the transport runs. The footer segment now routes through the activate actions, so a panel switch finally persists.
