The 1164585 AppID inherited from old project notes turned out to be wrong — actual Steam AppID for AI Apocalypse is 4652030 (with depot 4652031). This mismatch caused the initial SteamPipe upload attempts to fail with “Invalid Parameter” since depot 4652031 doesn’t belong to app 1164585. First successful upload: BuildID 22908122.

Swept everywhere the wrong AppID was referenced:

write_steam_upload_doc.py: now targets 4652030/4652031 in all VDF templates + example filenames + steamcmd commands. Also hardened Step 2 guidance: “always confirm AppID/DepotID against the Users & Permissions page — don’t trust old wiki notes” (AppID/Depot mismatch is the #1 cause of Invalid Parameter).
write_launch_kit_docs.py: press release kit, social post copy, Discord launch plan, etc. — all Steam store URLs now point to store.steampowered.com/app/4652030.
AI_Apocalypse_Steam_Deck_Checklist.md: 2 refs fixed.
All 5 launch kit .docx regenerated from the corrected script.

Not touched: archival devblog posts in the dist/ of the website — those reflect what the commits said at the time and shouldn’t be rewritten. Steam_Upload_Walkthrough.docx needs a manual regen after the user closes the Word window (Python update is already on disk).
