This PR rewrites the docstring on
Lean.ReducibilityHintsto accurately describe thekernel's lazy delta reduction strategy: which side gets unfolded when comparing two
definitions, how definitional height is computed, and how hints relate to the
@[reducible]/@[irreducible]elaborator attributes.The old docstring referenced a
selfOptflag that no longer exists and contained a fewinaccuracies (e.g.
irrelevanceinstead ofirreducible).🤖 Generated with Claude Code
