pub const MIN_BC_CONVERSION_TABLE_POINTS: usize = 7;Expand description
A conversion curve must contain more than the legacy six-row placeholder decks.
Point count is a capability guard, not a quality metric: the normal shape checks below still require aligned, finite, positive, strictly ascending data. Seven is deliberately the smallest value that rejects every retired six-point placeholder while leaving table-density policy to provenance review and golden tests.
