Bind, switch, release, a login's move and a rotation's advance each say one
binding.changed per consumer moved, with the licence's key, after the key of
bindings is written or deleted; a switch through the verbs says one
licence.switched with the from, to, consumers, by and why the audit's
switched entry also holds. licence.bound, released and rotated are said no
more. An adoption advances the consumers already bound before it moves the
login's nodes, so each is said once.
Builds: design 39 bus-and-switch §21, §27 (the verb's switch), §36, B7, B16
