GBM MVT paper snapshot adaptation
Copyright 2023, Universities Space Research Association (USRA). All rights reserved.
Authors named by the snapshot: Suman Bala, Narayana Bhat.
Original Haar method and code provenance: Nathaniel R. Butler; Golkhou & Butler (2014)
and Golkhou, Butler & Littlejohns (2015).

The snapshot explicitly declares Apache License 2.0 in MVTfermi/__init__.py,
pyproject.toml and docs/README.md. It does not contain a standalone LICENSE or NOTICE.
The included LICENSE.txt is the unmodified Apache-2.0 text from apache.org.
The original nrbutler/mvt repository has no independent license declaration found
in this audit. These declarations do not independently establish its permission
chain; resolve that provenance caveat before publishing the derivative files.
No permissions or copyright ownership beyond the snapshot declarations are asserted.

JinWu modifications: relative imports; removal of process-global matplotlib backend
and warning filters; lazy plotting imports; optional explicit diagnostic outputs.
The original mathematical expressions and numerical sequence are retained.
The validation model is copied from MVTfermi/mvt_snr_fit_model.npz in the frozen fork;
it is byte-identical to the model corrected in the parent commit a61d84c in
results/0_plots/mvt_snr_fit_model.npz. No calibration update is applied silently.
