open-topodockq-featurizer

This fixture stages the open replacement for the one piece of TopoDockQ that could not be run from source: its persistent-combinatorial-Laplacian interface featurizer. The reimplementation is MIT and clean-room, and it is validated as bit-exact against the original .pyc on 400 real complexes plus adversarial probes — an unusually strong form of evidence, available here only because a working oracle existed to compare against.

That is what makes topodockq-environment‘s bytecode gap closed rather than merely documented: the open scorer’s feature inputs no longer require any bytecode.

The environment stages two in-repo path recipes, its own and petls-pytorch-environment‘s engine, which is what holds it at L1. Both are pure-Python noarch and Bioconda-eligible, so publishing them promotes this fixture to L3 or L4. Verified green with a solved linux-64 lock.
