1//! Regenerate the canon's own instance manifest.
2//!
3//! The canon is an instance of itself, but not one the installer can
4//! produce: its files sit at their canonical authored paths. Recording their
5//! hashes by hand is how the manifest drifts from the payload, so it is generated from the payload instead —
6//! and only in the canon checkout, which is recognised by its own crate
7//! manifest.
