//! Gold-set JSONL parser.
|
|
//!
|
|
//! One file, one job: read the hand-labelled training set, drop anything
|
|
//! whose `quality != "gold"` (silver is noisy per spec), return clean
|
|
//! `GoldRow`s for the eval pipeline.
|
|
//!
|
|
//! Tolerant parse strategy: we deserialize into `serde_json::Value` rather
|
|
//! than a strict struct so upstream shape changes (extra columns, different
|
|
//! source tags) don't break the eval. Only the 4 fields named in the spec
|
|
//! are consulted: `category`, `text`, `source`, `quality`.
|
|
//!
|
|
//! One bad line is NEVER a fatal error — the whole file gets skipped only
|
|
//! if `fs::read_to_string` itself fails.
