NRDAX: pinned registry snapshot and mechanism classification (2026-07-24)

The data behind NRDAX: a mechanism-defined taxonomy for network-boundary and node-resource attacks on decentralised infrastructure. Every figure in that paper is computed from the registry snapshot and the per-technique mechanism assignment deposited here, and from nothing else. Anchor: snapshot taken 2026-07-24, 420 published techniques, SHA-256 f10db758ac7749606a3117bbd6517c2ab6911ebbf6e709f71f1bd6ef6e3bc726. Cite the date and checksum rather than the registry version string, which does not advance with each addition and so does not distinguish this state from a later one. Contents: the pinned registry snapshot (420 techniques with instances and external references); classification.py, the paper's per-technique assignment of 97 techniques to a mechanism family, surface and bound-failure mode; the first-pass resource-class audit whose difference from the final assignment is the derivation of the two axes; the figure generator, which reads only the committed data files; the three figures as SVG and PNG; and a sidecar listing the 43 classified records whose mechanism text is truncated at 200 characters in this snapshot, with the repaired text beside it. Note: the snapshot predates the classification, so its family column holds the producing pipeline's label, not the mechanism family the paper assigns. Join classification.py by identifier. See README.md for the full caveats, including what a release payload carries that this snapshot does not.
