BHI Research Notes
Short, dated research statements from the Black Hole Index measurement programme. Each note names its dataset and method version, states its evidence cutoff, declares its limitations, and carries an exact reproducibility statement. Notes are numbered, permanent at their URLs, and revised only by visible new versions — never silently.
