Scope of the NC restriction

This restriction applies to williamTLmiller's normalization and packaging
work in this specific form. It does NOT and cannot restrict the
underlying DROID recordings themselves, which remain separately
available under the Apache License, Version 2.0 from their original
source (see LICENSE-APACHE-2.0-UNDERLYING-DATA.txt and the link below).
Anyone is free to obtain and use the original source data under its own
Apache-2.0 terms; this license governs only this specific redistributed,
normalized package.

Underlying data
----------------
Derived from DROID (Distributed Robot Interaction Dataset),
https://droid-dataset.github.io/, obtained via the official
LeRobot-format mirror:

Modifications in this derivative
----------------------------------
Normalization into the MatrixNorm RoboticsGraph schema: per-timestep
flat table; training/eval task construction; episode-grouped
leakage-safe splits; relationship (HIN) edge graph; per-frame video
index; rights and provenance manifests; field-coverage validation.
Two corrupt source metadata columns (task_category, date) were
detected and excluded. No labels were synthesized.
