Enum HarnessConfigError 

pub enum HarnessConfigError {
    Toml(Error),
    Json(Error),
    UnsupportedSchemaVersion(u32),
}

F7 fix: schema_version previously parsed any u32 silently — a future (or simply typo’d) version number would be interpreted under TODAY’s field meanings with no warning at all, exactly the kind of silent misinterpretation §3.5 step 5’s “fail SAFE” precedent exists to prevent elsewhere in this migration. Only 1 is understood in P1.

Variants

Toml(Error)

The document isn’t valid TOML, or doesn’t match the schema.

Json(Error)

The document isn’t valid JSON, or doesn’t match the schema.

UnsupportedSchemaVersion(u32)

The document parsed fine, but named a schema_version this build doesn’t understand.
