# Fix the "joining room" / dorm-load crash on the VPS (ns.radicade.app).
#
# Root cause (proven from Player.log 15:59 session):
#   Dorm Room 2 / SubRoom 2 references DataBlob ebb4bab8-7206-41b8-8458-1db103ed22c7,
#   but the file is missing from the VPS CDN storage. The 2023 client 404s on
#   GET /room/ebb4bab8-..., loops "Data Mismatch -> Redownloading room details",
#   then a circuits-chain promise fires SessionManager.FatalApplicationQuit.
#
# Two independent fixes; EITHER ONE unblocks the join.
#
#   MODE 1 (data, no code change) : upload a valid minimal empty room-save blob
#           under the exact missing name via the admin API.
#           Run from anywhere (your Windows Git Bash works):
#             BOT_SECRET='<Radicade:BotSecret from the VPS appsettings>' \
#               bash VPS/fix-dorm-blob.sh
#           or:  bash VPS/fix-dorm-blob.sh '<the-secret>'
#
#   MODE 2 (code, durable)        : deploy the RoomUtils.cs self-heal already in
#           this repo (clears stale references on every room fetch) and restart
#           the service. Run ON the VPS, in the repo checkout:
#             bash VPS/fix-dorm-blob.sh --deploy
