//! Typed data structures returned by the SDK.
//!
//! The `*Info` structs mirror the JSON rows emitted by the `bsdkrun` CLI's
//! `--json` output (snake_case field names). The parsers are hand-written over
//! [`serde_json::Value`] rather than derived, because the same struct is fed
//! from two wire shapes: the CLI's rows and the daemon's camelCase GraphQL
//! objects, where timestamps arrive as decimal *strings* (the daemon passes
//! the CLI's own text through unchanged) and numbers may be widened to Float.
