aura --version prints aura 0.1.0 only, while run manifests stamp the engine commit. A stale binary is therefore invisible until after a run. Observed failure mode: a 9-day-old release binary at a pre-data-only-support commit failed aura run inside a data-only project with a raw cargo metadata failed: could not find Cargo.toml error, while HEAD had long supported data-only projects — nothing at the CLI surface distinguished the stale binary from an engine bug.

Research docs pin engine commits (Engine: aura @ <sha>); aura --version printing aura 0.1.0 (<commit>) gives those docs, and any agent, a pre-run freshness probe. The raw cargo error text in that failure mode is a small adjacent UX gap.
