When I fixed this, it was like magic, working how I wanted again. I now have a skill to periodically audit MEMORY.md and CLAUDE.md according to the conventions I've learned work best for me - which I suppose /dream is supposed to handle eventually, but you're kind of trusting it to audit its own memories, which have, at least to me, already proven to be unreliable.
With so many factors like this, not even to mention context exhaustion, window size, effort, etc. - anecdotal evidence is almost worthless without examining someone's entire local state.
A lot of it, to me, feels like user error, I haven't really noticed much behavioral difference between 4.5, 4.6, and 4.7, at least in my own workflow. I will note though that constantly managing these things is a lot of work that I hope one day becomes less necessary. It's more than I can expect people on my team to manage on their own, and unless I sit down with them 1 on 1 and review their issues, or write some clever agent to help them, I don't really know how I can help people reporting things that I hear posted here a lot.
