Zone conditions missing "Tampered"?

[djangosChef]

Protocol documentation (at least what I have) indicates that "Bit 1" (the second bit) in zone status condition (7th byte) is 'Tampered', but that condition is not included in STATUS_FLAGS for zone in model. Looks like controller uses 'Inhibited' to determine if zone is bypassed, which is confusing - might this be because the missing "Tampered" shifted everything after "faulted" down a bit?
