Release: a corrected classical sheet, with the on-shell obstruction separated

: a corrected classical sheet, with the on-shell obstruction separated{ The signed action, quadratic operator, metric Euler coefficients, Noether identity with its switching and gauge-fixing terms, and plateau covariance of the invariant metric Euler derivative are constructed.

For the fixed free input of Theorem thm:empty, the coupled Einstein jet is empty. The unrestricted jet family is not declared empty.

Neither invariance of the gauge-fixed action nor nonlinear covariance of a Fierz–Pauli-only truncation is asserted. Those versions of the proposed sheet are false. The metric remains off shell throughout the construction of the sheet.}
