Struct PreparedMetadata 

pub struct PreparedMetadata {
    pub refreshed_at: SystemTime,
    pub transform_applied: bool,
    pub sources_used: Vec<String>,
}

Per-transform telemetry. Captures whether the middleware actually ran (vs. passthrough) plus the names of the sources the transform consumed.

Fields

refreshed_at: SystemTime

transform_applied: bool

true when transform middleware was invoked; false for the single-source passthrough path.

sources_used: Vec<String>

Names of every source that fed the transform stage. Insertion order matches the YAML — preserved by carrying the IndexMap keys directly out of stage 1.
