//! Detect Zed threads.db by tables/columns from official bd74733 creation/migration SQL.

//!

//! had the expected threads columns but zero rows, verifying only the schema.

//!

//! V17 detection rules:

//! - Non-SQLite, absent threads or missing required columns is UnknownFormat.

//! - Matching threads columns, even with no rows, is Supported; empty files remain Pending in the framework.

//! - The format ID zed-threads-db-1 comes from source; it does not identify a product version.

/// Detect threads.db by its threads table and required columns.

// A busy/locked database is Pending for a later check, rather than UnknownFormat.

// A transient product-held lock remains Pending; do not persist it as a format conclusion.

// created_at is a migration column (official db.rs:460-483); the scanner handles its absence as an older database.
