A naive reply to Daniel's original question: also integer tetration depends in a certain way on complex tetration.
In order to try to explain my point, let us just take a look at Corollary 3.3./Equation (26) of my paper https://arxiv.org/pdf/2208.02622.pdf .
Basically (by assuming the standard decimal numeral system), it shows that if the tetration base is congruent to \( 5\pmod{10} \), then a peculiar property of integer tetration (i.e., the constancy of its congruence speed, which in the present case is guaranteed by the constraint that the height of the power tower is at least equal to three) uniquely describes a subset of those bases ending with the digit \( 5 \) returned by \( 90 \) degrees rotations on the complex plane (of course, we can achieve the same goal by using goniometric functions as showed by Equation (21)).
In the mentioned paper, in order to provide the inverse map of all the tetration bases with any given congruence speed, I invoked decadic integers and we know that \( \mathbb{Z}_{10} \) has the countability of the continuum, while this is not true for \( \mathbb{Z} \) and for \( \mathbb{Q} \).
Thus, I think that, if we wish to clearly see the whole picture and understand its true meaning (i.e., congruence speed \( \rightarrow \) phase displacement/"sfasamento" involving the rightmost unfrozen digits comparison \( \rightarrow \) chaos theory related stuff), including intrinsic properties characterizing hyper-4 itself (not only holomorphic functions constructed by us following tetration rules that we have previously defined, I mean), we need to look at \( \mathbb{C} \) before turning again our eyes on the "real" axis to the ground.

Let \(G(n)\) be a generic reverse-concatenated sequence. If \(G(1) \notin \{2, 3, 7\}\), then \(^{G(n)}G(n) \pmod {10^d}≡^{G({n+1})}G({n+1}) \pmod {10^d}\), \(\forall n \in \mathbb{N}-\{0\}\)
