The op-script error seam (OpError::UnknownNodeType) now consults the same tier-hint logic as the blueprint load path: outside a project the hint names the missing Aura.toml, inside a data-only project it names the missing node crate and the attach verb. Hint texts shared, load-path behaviour and the op-error prose byte-stable, exit codes unchanged. closes #244
