Ledger update and conclusion

No standing version-specific status elsewhere is updated. Any O.1=NOT_CLOSED{} entry remains so unless independently closed in its own stated scope; an independently reported subsector result is neither verified nor revoked here. XVI-N is not discharged, the downstream XV-B quantum-admission exit is not opened, and bulk_ symmetry_ restored{} is not promoted by this paper CheungOOneST,CheungEn09. These are non-transfers, not corpus-wide impossibility claims.

. Summing before continuation gives a global kernel whose only possible nongeometric branch point is the apex travel front. At its angular transition, reduced-variable pullback and the bisolution equations remove the spurious angular covectors that a moving-sector differentiation could create. The exact diffraction coefficient then supplies the lower bound, while finite-character projection identifies every nondiffractive sector. The resulting equality (eq:main) separates three facts: the covariance is locally Hadamard, its frequency orientation is globally controlled, and its global propagation relation need not be the relation of regular null geodesics alone.
