Sophomore year of college done. Mostly unremarkable — still ahead of the coursework, still spending more real hours on this than on classes, which I know is a risky ratio but hasn't bitten me yet. Been extending the memory system from last summer. It's not just per-batch summaries anymore — I built a lightweight retrieval layer on top, so when the Loop proposes something new, it can pull relevant past summaries (not everything, just the ones that look related) into context before deciding what to try. Basically giving it something like "here's what I personally recall about attempts similar to this one" instead of a flat pile of every summary ever written. The thing I actually sat down to write about: this week, unprompted, one of the generated proposal write-ups referenced an experiment from eight months ago by name — not because I asked it to look back that far, the retrieval just surfaced it as relevant on its own. It was right to surface it, too. The connection was real and I hadn't consciously made it myself. I keep trying to be careful about how I describe this to myself, because it would be really easy to start using language like "it remembers" in a way that implies something it isn't. It's retrieval plus summarization plus a scoring function. I built every piece of it. There's no ghost in it. But functionally, in terms of what it can do, it behaved exactly like something with continuity would behave. I don't know if that distinction — "behaves like it has continuity" versus "has continuity" — actually means anything, or if I'm just uncomfortable with how thin the line looks up close. Anyway. Logging it as a milestone: PROMETHEUS versions now meaningfully reference their own history without me hand-feeding it.
