A personal log. Numbered from Day 0 so the indexing matches how programmers count.

Each day = vignette. What shipped, what worked, what surprised me, the AHA in plain English. Commit hashes link to the actual diff.

The metric to watch as the log grows: optimal_pct — the fraction of tic-tac-toe moves werbos plays that match the minimax oracle. Higher = smarter. Day 1 baseline: 66.7%.
