codelore-lib 0.27.3

//! Asserts that the hardcoded dependency-version strings in the provenance
//! and arrow-facade modules match the versions actually resolved by
//! `Cargo.lock`. A dependency bump without updating these constants drops
//! a stale version into every provenance JSON sidecar codelore emits —
//! the provenance receipt becomes a lie. This test catches the drift at
//! CI time instead of in a downstream user's report.
//!
//! Implementation: `include_str!` the workspace `Cargo.lock` (resolved at
//! compile time via `CARGO_MANIFEST_DIR`), find the `name = "<pkg>"` entry
//! and grab the immediately-following `version = "..."` line.

const CARGO_LOCK: &str = include_str!("../../../Cargo.lock");

/// Look up the version string Cargo resolved for `package` at compile time.
/// Returns `None` if the package isn't in the lockfile (which would itself
/// be a test failure — the package wouldn't compile in the first place).
