Show HN: A Markdown file that turns your AI agent into an autonomous researcher

A single Markdown file (researcher.md) turns AI coding agents like Claude Code or Cursor into autonomous researchers that design experiments, test hypotheses, and iterate — running 30+ experiments overnight on a git branch. It tracks all experiment history in an untracked .lab/ directory, supports non-linear branching, convergence signals, and session resume, generalizing automated research beyond ML to any measurable metric.
