N. Cheung, Landmark XI-A: A switched Einstein–scalar action for the ramp relational scalar: sign conventions, Noether identities, and an empty fixed-input Einstein jet. Supplied companion manuscript. Used for the signed quadratic operator, the switching conventions, and the fixed-input Einstein-jet obstruction.

VIIC

Landmark VII-C: A mixed-Wick obstruction to a normal-topology boundary extension for sharp Cauchy harmonic insertions. Supplied comparison manuscript. Used only for the extension checklist; its free matrix and products are not inputs to the present construction.
