One thing I'm wondering with hindsight is whether the return portion
of my CDR from Cambridge to London Terminals would have actually been
valid for a trip from Stratford to Enfield Lock? In the event, I ended
up going straight back home from Enfield Lock, changing at Cheshunt,
rather than returning to Stratford.

I don't think so. The Routeing Guide only gives this one map:

Since Stratford isn't a London Terminal, you can't use the branch on
the right on your ticket. But you can use your ticket on that line
north of Tottenham Hale, so you only needed to buy a Stratford-
Tottenham Hale ticket.

Also, as I mentioned, PAYG would also cover Stratford-Tottenham Hale,
though you'd have to get off your train to touch out, then re-enter
with your train ticket and get on the next one.
