Explains the scratch codebase — a fast, per-worktree markdown scratchpad TUI (Go / Bubble Tea). Use when working in, extending, debugging, or trying to understand THIS repository: its architecture (the notes file layer, the Bubble Tea model, the fsnotify watcher), the non-obvious design decisions (atomic writes, the Classify reload decision, serialized autosave, the terminal-probe focus dance, directory-watching), where the design specs live, and how to build / test / run / release.
