Interesting to see this gaining traction. I've been building something similar in a sense. It's called XI-eXtended Intelligence - that takes a different angle on the integrity problem. MemPalace solves retrieval really well. XI is more focused on what happens when memories are wrong or conflict over time- signed journals amandment overlays (amending, not replacing memories that need updated for whatever reason), auditing. Happy to share the project if anyone is interested.

I would love to check it out. I rolled my own with an approach that sounds similar, my repo is here if anyone is interested: https://github.com/shane-farkas/memento-memory
