# THJ AA gaps (2026-10-04): install the staged spells_us.txt + dbstr_us.txt (= current shipped patch_files + spell 17781
# Dimensional Armory + 7895 Holy Shield, AA strings 18973 Situational Awareness, 50000 Dimensional Armory, 10548 Holy Shield)
# (default: Trevor's desktop client) for testing on the TEST world. Backups: *.bak-thjaagaps (made once, from whatever is there).
# Run on the desktop:  bash install_desktop.sh [client_dir]     (after copying this folder there)
# Launch with the "(Direct)" launcher: the Patcher launcher puts the shipped (live) files back.
# Undo: bash install_desktop.sh --revert [client_dir]   (or just run the Patcher launcher once)
