txcript 0.1.0

//! A typed intermediate representation for AI coding-agent session transcripts.
//!
//! Claude Code, Codex, OpenCode, and pi all record the same thing — a sequence
//! of user/assistant turns carrying text, reasoning, tool calls, tool results,
//! and images — in mutually incompatible on-disk formats. This crate models
//! that shared shape once, as [`Transcript<Common>`], and gives each harness a
//! [`Codec`] to and from it. Converting a session from one harness to another
//! is then [`convert::<A, B>`](convert): `A` → [`Common`] → `B`.
//!
//! # The two-layer fidelity contract
//!
//! - **Native ↔ disk is byte-lossless.** Each harness keeps a faithful typed
//!   representation of its records ([`Harness::Body`]); a [`Store`] round-trips
//!   it to disk without loss. This is what a same-harness resume uses.
//! - **Through [`Common`] is semantically lossless.** [`Codec::to_common`] may
//!   canonicalize representation so a thread is functional in another harness,
//!   but it never discards detail: anything a same-harness round-trip needs is
//!   preserved in [`Common`]'s typed fields. It is not byte-exact, by design —
//!   canonicalization and byte-faithfulness pull in opposite directions, and
//!   byte-faithfulness already lives at the native ↔ disk layer.
//!
//! # Shape
//!
//! - [`common`] — the canonical model ([`Message`], [`Block`], [`Tool`], …).
//! - [`Transcript`], [`Harness`], [`Codec`], [`Store`] — the generic type and
//!   the traits over it.
//! - [`harness`] — one module per implemented harness.
