584 — The Source Quartic Is Not the Diagonal Connection of the Proper Top Line
Hard-to-vary claim
If the source quartic is the diagonal transport divisor of the physical proper top line, then the connection induced on the canonical quotient generated by must agree, up to the sign convention of the square root, with
Canonical quotient
Let be the span of the three codimension-one deletion faces. Entries 581--583 establish that this span is canonical in the tested presentation and is preserved by . Entry 582 identifies
The present checker independently reproduces
Therefore reduction of modulo determines a canonical scalar relative to the literal source generator:
No complement or solver section is chosen.

None agrees with either sign of the half-logarithmic derivative.
Narrow conclusion
in the tested literal product-pole Gauss--Manin presentation.
This removes the last canonical absolute rank-one candidate presently available: the fitting-conic line failed descent in Entry 528, and the physical proper top line now fails the -connection test.
It does not show that is absent from the full connection. Since the boundary span is connection-stable while the quotient is rank one, the remaining typed location is off-diagonal extension/relative-chain data in a supported enlargement not visible in the quotient scalar.
No carrier modification is indicated.
Next falsifier
Compute the connection of the literal top generator before quotienting and extract its canonical second-fundamental-form class in the boundary-span cokernel appropriate to the supported physical chain. Test whether its pole support contains . Separately complete the mixed-second-jet curvature audit of the deletion diagram.
