Struct HeaderSniff 

pub struct HeaderSniff {
    pub version: Option<RustyfiVersion>,
    pub envelope_headers: bool,
}

What sniff_headers learned from the header block. version is exactly sniff_version’s result (Axis A); envelope_headers is the Axis-B signal the CLI’s detection ladder needs — a use-shaped header pins Axis B = LoadMode::Envelopes, and sets BOTH fields.

Fields

version: Option<RustyfiVersion>

The detected target version, if any (None = ambiguous/no signal).

envelope_headers: bool

Whether a use-shaped (Envelopes/Saphe) header was seen. When true, version is also Some(V0_1) (a use header is a 0.1-only construct).
