Runtime mirror of RevTurbineUpdateInput’s keys — the fields update() patches. satisfies guards each entry against typos/renames; the aliases test asserts exhaustiveness against the type, so a schema-added context field fails the build until acknowledged here. JS callers’ keys outside this set are dropped with a dev warning rather than merged into the context.
