When the fourth activity appears, the context is checked, C's reply isn't in it, and I proceed without knowing about it. Oops!
I don't understand this part. Is C's reply being dropped?
I think if you encounter an object where inReplyTo is not known to you, that unknown object should be fetched, regardless of context.
this is related to FEP f228.
FEP-f228 specifies a backfill algorithm that works from top-level post down the thread. But it would be nice to provide an algorithm that works for any post in a thread. I'll think about it.

C's reply didn't get dropped, it simply didn't include A, the original server. The last reply did, but because the context was A, it never contained it, so it never pulled it. inReplyTo isn't checked when utilising context-backfill because it is supposed to replace having to do that. Except not in this edge case :slightly_smiling_face:
