Salty.uproject (UE 5.8) from the Third Person template with class redirects, the SaltyCore and Salty modules, the three build targets, USaltyAssetManager calling InitGlobalData, Config/Tags with the 23 root namespaces, Scripts/run-tests.sh, build.sh and Authoring/create_gym.py, L_Gym, Git LFS attributes and the placeholder test. Template variants kept as reference (D-41). The four Fab packs stay out of the repository for now (~10 GB). The editor serves the engine MCP plugin on 127.0.0.1:8000 through DefaultEditorPerProjectUserSettings.ini. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

"""Creates /Game/Maps/L_Gym if it does not exist: a flat floor, a player start and daylight. Idempotent.

Step 1 wants an empty gym; step 3 extends this script with the greybox sections from Movement.md (stairs, slopes,
|
|
gaps, ledges, doorways, beams, corridor, surfaces, arena). Run headless:
|
|
UnrealEditor-Cmd.exe Salty.uproject -run=pythonscript -script=Scripts/Authoring/create_gym.py
|
|
or from the editor's Python console. Never hand-edit the .umap; rerun this.
