Surface

Generated by scripts/surface.sh — do not edit. Regenerate with make surface.

Every top-level declaration in the engine, with its line. Read this before opening a source file: it answers "where does X live" and "what is in this package" without the bodies. What each file is for lives in state.md; why it is that way lives in decisions.md.
