This gave me the idea to start specifically crosschecking
feature-interactions with Claude: instead of focusing on reviewing one
feature, reviewing how 2 or more features interact (for all existing
features on master, starting with an initial ranking session then
separate sessions for combinations based on that initial ranking, also
including 3-or-more feature interactions where it thinks that it would
be worth a check). The initial ranking itself surfaced 4 actual
issues, and the few more detailed runs I completed so far from the
longer task list brought up more questions/issues. The entire list
will take some time to run, I'll post some bug reports / patches.
