Even if your Oyster contains a valid travelcard for the whole journey, you

No you aren't. Not if the gates are open/ungated, etc. Only pre-pay
users must present their cards.

If an
RCI catches you halfway through your journey with an unswiped Oyster
containing a valid travelcard for the zone in which you currently are, this
looks suspicious but you would presumably just be warned to swipe in future.

Why - you are not required to?


If the RCI catches you are out of your valid zone with an unswiped oyster,
you can then be busted.

Why? See above.

If you are out of your zone with a swiped Oyster,
then you are obviously intending to swipe on exit and be charged for the
extension... if you don't swipe on exit, you will be charged the maximum
possible extension (to zone 6D or whatever).

How will you be charged if you don't swipe? It doesn't know where you
are - you could have got out at a open station within your zone.
