This inventory lists source provenance, retained notices and component-specific terms. Some components have non-commercial or copyleft conditions.
The root MIT license covers original OccStress code authored by the OccStress authors, not third-party code or derivatives subject to other terms. Retain upstream notices, including notices inside nested dependencies. See third-party notices for the scope of exceptions.
We checked the complete GitHub source-tree notice inventory and root README of 19 model repositories plus RoboBEV and Robo3D. We also checked the specific MIT-licensed II-World base used by the experimental checkout. The pinned revisions, source links and findings are in third-party-audit.json. Current upstream revisions there identify the audit target, not a claim that every imported file came from that revision. Imported source provenance remains in source-imports.json.
The inventory describes repository-level sources. More specific notices inside individual files and nested dependencies remain applicable.
| Component | Finding and action |
|---|---|
| COTR | The local experimental base and official commit 4328e0a contain Apache-2.0. Restored the exact omitted EXIST/3D/COTR/LICENSE. |
| II-World | The experimental checkout is based on MIT-licensed 2b487f8. Restored that exact notice. The later upstream commit 661d830 deletes it; we do not infer a grant for later or unrelated code from this restoration. |
Both restored files match the pinned public files and the local experimental Git objects byte-for-byte. Their origins are recorded in the import inventory. OccStress adaptation edits remain distinct from the upstream base.

The following root notices are present and match the versions inspected in this audit. This does not supersede more specific notices inside each tree.

| PanoOcc | Robertwyq/PanoOcc | GPL-3.0; not MIT |
| SparseOcc | MCG-NJU/SparseOcc | Apache-2.0 |
| STCOcc | lzzzzzm/STCOcc | MIT |

RoboBEV's README
and Robo3D's README
declare CC-BY-NC-SA-4.0, with operator-specific exceptions. The absence of a
root LICENSE file does not mean the READMEs contain no grant.
Robo3D's nuScenes fog subtree
instead carries CC-BY-NC-4.0. Its lookup tables remain external.
The Waymo/CARLA camera and point-corruption adaptations identify those sources
and revisions. Review copied/adapted portions and operator exceptions before
distribution; do not label them as unrestricted MIT merely because they are
outside EXIST/. Preserve source attribution, modification notices and all
applicable non-commercial/share-alike conditions. Consult the linked upstream
READMEs for operator-specific exceptions.
The 2026-10-06 asset distribution review distinguishes official weight references, project experiment weights and dataset-specific sharing conditions. It also records the designated Hugging Face dataset repository.
Code permission is separate from weight/data permission. In particular, EFFOcc's README states that its Occ3D-Waymo checkpoints are not shared due to Waymo rules. This records the upstream restriction, not an independent interpretation of every Waymo-trained checkpoint. Weight and dataset terms apply independently of hosting on Google Drive or Hugging Face.
The current Waymo agreement permits conditional non-commercial model/weight distribution. The upstream EFFOcc statement above is not a blanket prohibition on publishing every independently trained Waymo checkpoint; use the separate asset review before making that decision.
Use CITATION.bib for OccStress and references.bib for the actual methods, datasets and corruption frameworks used. Citation guidance maps components to keys and records source provenance. Preserved upstream READMEs remain the primary source for their own recommended citations. Citation is scientific attribution, not a replacement for a license.
