The console-wide view of recall-safe: which channels (and which scopes on them) a recall
leaves alone. Live console state the operator drives during a show — never stored inside a
scene.
DERIVED, never held. Each channel owns its own decision in the
/channel/{kind}/{index}/recallSafe row; this shape is what recallSafeMaskOf folds
those rows into at the moment a recall needs one, and it is discarded again. A stored mask
beside the rows would be a second owner of every channel's fact.
