Description

I think ultimately inner/loginner for TT should just be designed based on calling a more general contract function with a contraction sequence appropriate for a tree network, and we can use a tree traversal as a way to quickly derive a reasonable sequence, and users can pass their own contraction sequence or function for computing a contraction sequence.

Research direction

Review the existing TTN inner and loginner behavior alongside the general contract API. Explore how a tree traversal can derive a contraction sequence, and define how callers can provide their own sequence or sequence-computing function; the work is done when both operations use this contract-based approach.
