Struct HeadingHint 

pub struct HeadingHint {
    pub chapter: u8,
    pub heading: Option<u16>,
    pub subheading: Option<String>,
    pub rationale: &'static str,
    pub confidence: f32,
}

HS chapter / heading hint derived from SMILES functional group analysis.

Fields

chapter: u8

HS chapter number (e.g. 28, 29).

heading: Option<u16>

Four-digit HS heading (e.g. 2914 for ketones). None when only the chapter can be determined.

subheading: Option<String>

Six-digit HS subheading when structural features allow it (e.g. "291411" for acetone). None when only the 4-digit heading can be determined.

rationale: &'static str

Human-readable rationale for the hint.

confidence: f32

Confidence in [0.0, 1.0]. Capped at 0.70 for heading-only results; up to 0.90 when a specific 6-digit subheading is identified.
