Licence notices
Course downloads preserve their included source notices and licence files.
DOOM integration
The Section 1 package includes a modified doomgeneric/DOOM source integration and a complete GPL-2.0 licence text. It does not embed a retail, shareware or Freedoom WAD. Learners may supply a legally obtained compatible WAD or download the separate official freedoom-0.13.0.zip course asset. That upstream archive includes its BSD licence, credits and manuals and is distributed unchanged.
Corresponding source
The Section 1 bootable completion kit includes the ForgeOS adapter, local modifications, build script and DOOM source used by the packaged integration. GPL-covered material remains clearly identified and is not relicensed by the course terms.
The separate Lifetime complete-source download reproduces the authoritative original ForgeOS.zip byte-for-byte from five protected parts; it does not trim or replace any internal source or notice. The supplied archive does not identify the exact upstream doomgeneric commit/tag, so the local snapshot hash and provenance limitation remain documented in the engineering audit.
Other components
Third-party sources and assets retain their upstream copyright and licence notices. Consult the LICENSES, provenance and manifest files inside each download before redistribution.
