Release and legal ending

and legal ending{ Overall ending: Unresolved. The quantum extension, its product, and its admission map are not constructed. The classical tree remains the XI-C symbol.

Two precise results are proved: an exact off-shell-shadow interpretation of the unchanged free-shell algebra is incompatible with its equations; and the bare insertion fails a necessary free-order closure condition for explicit admissible observation tests.

The latter is a conditional obstruction to closure, not a theorem excluding admission alone. No quantum class is released.}
