Kill switches

getKillswitch(name) returns a Boolean: true when the kill switch is killed (the feature should be turned OFF). Kill switches ride in the same flags blob as gates and configs.

Bound Client form

val flags = Client(currentUser)

if (flags.getKillswitch("payments")) {
    // payments are killed — short-circuit
    return serviceUnavailable()
}

Named per-switch override key

A kill switch can carry named per-key override switches. Pass switchKey to read one specific named switch: true when that named override is on.

flags.getKillswitch("payments", switchKey = "eu_region")   // → Boolean

If the named switch key isn't configured for this kill switch, the read falls back to the kill switch's top-level value (the plain getKillswitch(name) result).

Semantics

• Without switchKey: returns true when the whole kill switch is killed.
• With switchKey: returns true when that specific per-key override switch is on; an unconfigured key falls back to the top-level value.
• Unknown kill switches return false.
