The rotation test failed twice under parallel runs ("never: the rotation begins"), from two races in
its player. The player refused mesh/subscribe, so the placement events it said never reached the
vault: when the vault's first view was answered before the test wrote the placement, the vault never
knew the bus node. And the test wrote the bus node's have right after the placement, so the vault
could hear the have before it applied the placement, adopt nothing, and never learn the loaded list's
revision. The player now answers mesh/subscribe and holds a family's events until it is subscribed,
as the module's consumer does; the test writes the placement only after the vault's first view and
the have only once the vault's picture holds every placement key (vault_first_views), so both orders
are fixed rather than waited out.
