Release and proof boundary

and proof boundary{ Constructed: the graded polynomial product, regular presentation, free-shell descent, frozen free differential, ordering transport, ordering-stable composite sector, the delimited continuity statements, observation robustness, and the regular ambient–slab identification.

Proved obstructed, conditional on the stated XI-G input: admission of the detected cubic classes into this carrier.

Unresolved or not opened: undetected observations, restriction to the Einstein subshell, global product hypocontinuity, completeness, and enlargement. Absence of an enlargement construction is not a no-go theorem.

The predecessor obstruction is copied, not reopened. No state, interacting differential, quantum retarded product, time-ordered product, loop construction, or sharp-width limit is introduced.}
