This is a builder's log, not a launch. I'm in the middle of a problem and I want to think out loud about it, because the people who replied to my last post moved my thinking more than a month of solo work did.

The moment it clicked

Last week Copilot told me a match scheduled for June 12 was still going to happen. Confident, future tense. I was reading it on June 20. The match was over.

The data wasn't wrong when it was retrieved. It went stale in the gap between retrieval and the moment it reached me, and nothing in the pipeline noticed. The agent had no sense of "now." It treated a fact from eight days ago exactly like a fact from eight seconds ago.

That's the thing I keep running into. We've taught agents to retrieve and to reason. We haven't taught them what time it is.
