Store "not available" root cause reversed from CardsDLL:
- ut/v2/game/fifa17/store is an ELIGIBILITY gate (FutStorePackQuantities
deser 0x1801758c0), not a quantity list. It reads one key "result"
(atom 0x288); the store screen refuses to open unless SUCCESS. Was
unhandled -> catch-all {} -> "not available". Now returns {"result":"SUCCESS"}.
- Store-screen entitlement checks (0x18001749d/0x1800175a2) read IS_*/
*_PURCHASE_ENABLED Blaze flags, separate from storeEnabled. Added the full
confirmed set (14 flags) to FUT_RS4_CONFIG.
- Catalog: assetId (0x23) is the real pack identity; extPrice inner keys are
amount/currency (not mtx). (Also gated client-side by GetSystemMetrics>1024x768.)
Full FUT API reversed (clean-room, CardsDLL only) into docs/ENDPOINT_MAP.md:
~100 FutXServerResponse types across 7 feature groups (market, SBC, draft,
seasons/match, club, store, user/hub), each with deserializer VA, atom-mapped
field schema + types, freeze-risk flags, and minimal known-good JSON.
Tooling kept: tools/atomdump.py (dumps the 907-atom key table at 0x1802d2760)
-> docs/fut_atoms.tsv. Research prompt: docs/OPENCODE_ENDPOINT_PROMPT.md.

A full 88-rated real FUT squad (Ronaldo/Messi/Suárez/Ramos/Kroos/Alba/
Hazard/Oblak/Alaba/Boateng) renders 100% offline, no EA servers.
Mechanism: the definition fetch was unnecessary — FIFA has all player
identity locally in dbdata.dll. The CLUB-SEARCH / Add-Player flow
(GET /club?type=player&count=N, served by our /club route) makes FIFA
resolve each item's assetId against its own local DB (real name/photo/
club/nation) and merge the rating/attributes our /club item carries,
caching a real record in the CardsDb store. No idList fetch, no leaked
data.
Recipe: utas FUT_SQUAD_STEP=s3v0 -> /club serves the full XI; in FUT,
Squads -> Add Player/search -> results render real -> add to slots.
docs/CARD_SYSTEM.md updated with the SOLVED mechanism + recipe.

Milestone: FIFA 17 Ultimate Team boots end-to-end on our offline backend
past every EA gate into the hub and a live Squads editor (correct 4-4-2,
5-star squad, no freezes).
Key findings this session:
- userMassInfo MUST stay {} (any content desyncs the massinfo parser
0x180174630 -> tokenizer busy-loop freeze). Deliver the squad via
GET /squad/0 (fetched on Squads-tab entry) instead.
- Player cards render generic because the card view-model (0x1800d7920)
reads identity/rating/face from a resolved record at item+0x10, filled
by a lookup (0x18011cca0) in the FUT item-definition std::map at
CardsDb+0x160c0 -- which is EMPTY offline -> default blank record.
- Version advertising (itemDbVersion/checkServerDbVersion) is proven inert
(JSON fields routed to the skip handler). Owned items don't auto-trigger
a definition fetch. In-place map overwrite is dead (map stays empty).
- Definition-serving endpoints (item/resource, defid, item?idList) built +
ready; the fetch trigger lives in the packed FIFA17.exe.
New: docs/CARD_SYSTEM.md (findings + ordered next-steps plan for real
player cards: patch-POC, dbdata extractor, drive FIFA17.exe fetch, or
live-memory store injection). Plus tools: fut_seed.py (squad ladder +
definition serving), fifadrive.sh, vgamepad.py, and the login-RE toolset.

Emulates FIFA 17's full online + Ultimate Team stack against an offline,
clean-room backend (no EA servers). Proven end-to-end 2026-08-01:
Origin login -> Blaze login -> device-trust -> the FUT hub.
Package:
- tools/openfut-fut.sh one-command orchestrator (start/stop/status/restart)
- tools/root_arm.sh idempotent host arm (sysctls, DNAT, /etc/hosts easw)
- tools/{lsx_responder_v2,blaze_responder_v3b,roster_server,utas_server,autopatch}.py
the 5 servers (Origin LSX :4216, Blaze :42127/42130/42131, roster :8081,
FUT/UTAS :8099) + heat2.py (Fire2/Heat2 TDF codec)
- FUT-RUNBOOK.md runbook + gate-ladder troubleshooting
- docs/, tools/login_dump/*.md the reverse-engineering write-ups
All findings are clean-room, from binaries we own; nothing from any leak.
The wire protocol maps 1:1 to FIFA 23.
