+              A Grid row rather than a sibling in the Panel below it — the terminal, the pages and the
+              connecting card are all layered on top of one another there, which is right for three things
+              that occupy the same rectangle and wrong for a row that is supposed to sit above it. Auto height
+              and IsVisible="False" collapse to nothing when there is nothing to show, so a page screen or an
+              empty terminal loses no height to a row it never draws — see ShowsPinStrip, which is false on
+              every page and every tab whose host has no pins.
+
+              ActiveTabPinnedPaths is MainWindowViewModel's, not the vault's: which tab is selected and
+              whether its session is live are the shell's business, and RefreshConnectedHosts is where the
+              two lists — Tabs and Vault.Hosts — are already walked together to paint the status dots. This
+              rides along on the same walk rather than opening a subscription of its own.
