Mixed component licensing — not a blanket relicensing grant.

The NTSD Core adaptation code identified as such is GPL-3.0-or-later. Applicable adapted Nuclear Tech: New Horizons (NTNH) material remains CC BY-NC-SA 4.0, with credit to Bufka2011 and the NTNH contributors. This statement does not convert older CC BY-NC-ND inputs or third-party content to CC BY-NC-SA.

Separately retained resources keep their original licenses: legacy AE2 textures/icons are CC BY-NC-SA 3.0; legacy HBM and ModernMarkings materials and EnhancedLootBags-derived components retain their bundled GPL terms; Chisel tool art retains GPL-2.0-or-later; OpenComputers, Storage Drawers and ArchitectureCraft materials retain their respective MIT notices; ExtendedAE demonstration structures retain LGPL-3.0 terms. The PneumaticCraft-derived recipe resource is GPL-3.0-only. Press Start 2P is unmodified and remains under SIL OFL 1.1, including its Reserved Font Name notice.

The binary's LICENSE and META-INF/licenses/ and the version-matched corresponding-source archive provide the component notices and source inputs. Where a third-party component specifies a fixed GPL/LGPL version, no later-version permission is added by this project. Preserve all notices and obtain the corresponding source with the binary. Do not apply All Rights Reserved or a blanket noncommercial restriction to GPL, LGPL, MIT or OFL components.

NTSD project visuals supplied by BySally are identified as AI-generated with OpenAI. Their provenance is separate from the code licenses; no automatic exclusive-copyright claim or new blanket artwork license is made. Third-party reference rights are unaffected.
