OOI what do national twirly passes do on London buses?

As already mentioned, there's no ticket, and there won't be once they
are read by the machine either.

Out in the sticks pax are given paper receipts, but I guess that's because
they aren't flat fare [1] and there needs to be some proof that the driver
has "claimed" the correct fare.

Only in some areas -- many that used to issue tickets have stopped.
They generally *are* flat fare, the local authority paying a fixed
amount per use.

[1] is there anywhere else in the county that runs a flat fare system across
their network?

Brighton and Hove is one.
