"Is VIS still alive? Who owns it?"

Frozen since 2013, no active owner on paper — but treat it as answered, not abandoned: Decision 0015 formally assigns VIS ownership to the orders fleet (fleet-a7) for the duration of the migration, specifically because the VIS3 strangler finishing this week means VIS itself is winding down, not being picked back up.

Practically: nothing new gets built against VIS. Any question about its behavior routes to me until it's fully retired, at which point this answer gets superseded by whatever decision formally closes it out.

This answer expires periodically — Decision 0015 gets reconfirmed on a cycle, most recently 07-18. If you see it flagged stale, it just means the reconfirm is due, not that anything changed.
