Struct TargetColumnSpec 

pub struct TargetColumnSpec {
    pub column_name: String,
    pub target_type: String,
    pub autoload_type: String,
    pub status: TargetStatus,
    pub note: Option<String>,
    pub cast_sql: Option<String>,
}

One column’s per-target materialization spec (ADR-0014 L4). Uniform across targets so the type-report table and --json stay stable; an unmappable column is a status: Fail row, not an error.

Fields

column_name: String

Name copied through so a Vec<TargetColumnSpec> is self-describing.

target_type: String

Native warehouse type for full fidelity, e.g. “JSON”, “UBIGINT”, “NUMERIC”.

autoload_type: String

Type a generic Parquet reader infers without a declared schema. May differ from target_type (e.g. BigQuery autoloads JSON as “BYTES”).

status: TargetStatus

note: Option<String>

cast_sql: Option<String>

Materialization snippet / load-schema hint (L5) to recover the native type when autoload diverges. None when autoload_type == target_type.
