+//! Boot manifest bootstrap mechanism.
+//!
+//! Fixes the "repeatable, tied to instance generation" installation step
+//! described in the PRD's "Boot manifest and readiness" section. This is not
+//! a full base-image build pipeline: it is a small, versioned, idempotent
+//! shell bootstrap that a Fly Machine's `init.exec` runs on boot to install
+//! (or verify) the pinned dependency versions recorded in a [`BootManifest`].
+//!
+//! The mechanism is intentionally simple: the machine boots with
+//! `TREQ_BOOT_MANIFEST_VERSION` set as an env var (see
+//! `remote_provider_sprites::SpritesProvider::boot_manifest_env`), and the
+//! bootstrap entrypoint looks up the manifest for that version and installs
+//! it. Running it twice against an already-bootstrapped machine is a no-op
+//! check, not a reinstall, which is what makes wake/reprovision safe to
+//! retry.
