Coherence of the actual particular increment #
The source is the residual of the current state. Its reference value is rebased to the native cover before solving. The identities below retain the full auxiliary fibers and the differentiated copy cutoffs.
Copy transport from continuity on the anchored interval #
The actual Volterra constructor depends only on the coefficient and converted forcing paths on its finite interval. These lemmas require continuity of exactly those paths, including their endpoints. No continuation of the raw tangent data or source outside the interval is assumed.
The derivative of the existing constructor needs only its two continuous input paths on the actual integration interval.
Uniqueness compares actual solutions on the finite interval.
Affine clock transport of the anchored solve, with finite-path hypotheses on the reference interval alone.
Parameter/cover/source transport and exact equality of converted inputs are algebraic. Only clock transport uses the two finite-path hypotheses.
Exact zero-entry velocity transport from the reference interval [0,L].
The coefficient and the two converted forcing paths are the only analytic
inputs, all restricted to that finite interval.
The actual pressure retains both the clock/normal factor and the ratio of reference to current frequency.
Continuity of the converted forcing can be checked on the finite native coefficient segment and the corresponding finite common-coordinate path.
Equality of the literal periodized velocities. Only active copies need
continuous reference paths, and only on the interval [0,L].
Equality of the literal periodized pressures, with the same finite reference paths and the actual inverse-frequency scaling.
Naturality of the actual Gaussian cutoff error #
The error is the sum of differentiated-cutoff terms and the uncovered source. Both terms are transported from their primitive data before the copy sum is taken.
Only copies with a nonzero differentiated reference cutoff need an amplitude comparison. No exterior continuation of a Volterra solve is assumed.
Full transport of the actual Gaussian error, including the source on the part of the domain uncovered by native cutoffs.

A nonzero actual directional derivative is supported in any closed set supporting the original cutoff.
The fast transport hypothesis follows from the actual slot-direction identities stored by the primitive copy geometry.
The actual transported reference solve has the derived Gaussian source weight on the full native cylinder, including uncovered points.
A single actual Gaussian Fourier contribution transports with its full angular carrier. The reference phase relation is primitive block coherence; the Gaussian coefficient relation is proved from the solve.
Naturality of the actual finite Gaussian harmonic block, with all angular variables retained. No equality of Gaussian outputs is assumed.
The same finite-block statement on the original full cylindrical
coordinates, with the source weight explicitly written as c^2 * l.
Continuity on the actual finite tangent-copy intervals #
The projected operator is built from the selected frame's normal, normal motion, base action, and damping. Only the native slow point and finite clock interval enter its regularity; the transverse coordinate is free.

The actual ambient projected operator and forcing projection of the selected frame are continuous on the entire closed slot.
No transverse or copy restriction occurs in these two primitive slice continuities. The only spatial hypothesis is the actual native phase cell.
A nonempty refined source fiber supplies the native phase-cell hypothesis. All copies and every transverse coordinate are then covered.

The target operator is the literal common-cover graph at the target band. This identification is independent of the current source.
Local agreement of the two primitive inputs propagates through the entire curl correction, including all cutoff derivatives.
Forward cover order: the germ inputs are consequences of the current state and coefficient identities, not assumptions about the solved wave.
Composition of the actual primitive copy data #
These identities allow two current bands to be compared directly. In particular, they do not require extending a current reference-band state outside the slow overlap on which state coherence was proved.
Actual source transport on the two-band overlap. All fast variables remain free, and all excluded residual terms are retained.
