The Global Observer Lift Precedes Authorized Quasidiagonality

Authorized quasidiagonality is meaningful only after sewing and cutoff are defined on a common completed carrier. That object does not yet exist for the full arithmetic boundary.

The distinction is forced by two exact results:

• continuous log-window projection is maximally nonquasidiagonal for ordinary Fourier transform;
• finite arithmetic reciprocal sheet transport commutes exactly with prime cutoff in the Fourier-saturated pro-Gram grades.

These are different carriers and different operators. Neither supplies the missing global map.

The first live construction is

$$\mathcal J:A_{\mathrm{additive}} \longrightarrow B_{\mathrm{boundary}}$$

with componentwise naturality

$$\mathcal J\mathcal F_A = \mathcal F_B\mathcal J$$

before scalar evaluation or finite projection. The boundary object must keep primitive, square, connected-tail, seam, and archimedean grades separate. Only after this passes may its authorized diagnostic projections be tested for quasidiagonality.

The revised immediate target is to derive the primitive and square components of J directly from the additive theta source and compute their typed Fourier–Poisson naturality residuals.
