//! What:
//! The normalization-only commit: a correction whose complete intended tree equals the recorded base ends without an empty
//! commit, and says so.
//! Why:
//! The preparation (`service_prepare.rs`) decides it before anything is sent to the service; this module holds the finding's
//! identity and its message, so the words of the finding stay in one place
//! (`src/policy-engine/commit-transaction-no-change.ts`).
//!
//! In TS you'd write (pseudocode):
//! ```ts
//! const message = noChangeMessage(conflicted);
//! ```
