Second session. FUT core loop, the EASFC/POW online layer, a central account
backend, and a lot of corrections. Everything risky is behind an env flag with
the default set to whatever was live-proven.
WORKING END TO END (live-verified this session):
* match loop -- POST/PUT/POST/DELETE ut/%s/match, rewards via FutDestroyMatch
(0x180121b60). Play a match, get coins, W/D/L updates.
* packs -- buy, cards land in the club, session survives (FUT_PACK_AUTOCLUB=1)
* quick sell -- POST ut/delete/%s/item was UNMAPPED and paid NOTHING; six cards
were destroyed for 0 coins. Now credits discardValue.
* POW/EASFC online -- the "EA FC servers unreachable" banner is powdll's layer,
a THIRD http api on :8094 nobody had served. Redirect needs no root: powdll
FUN_18005a460 reads FIFA_POW_URL from the same client-config store as
ROSTERUPDATE_URL. FUT_POW=1.
* account backend -- fut_account.py replaces 7 hardcoded copies of the persona
across 5 files; club/persona/online-profile editable via CLI.
CORRECTIONS TO ENDPOINT_MAP (all re-extracted from the deserializers):
* FutStoreGetPackTypes: id/packType/isPremium/quantity/saleType/purchaseLimit/
purchaseCount are NOT skipped no-ops -- all are parsed. extPrice inner objects
take externalPriceId(0x11a), not amount/currency.
* FutMoveCard 0x180128600 has NO skip handler (FUN_180135ff0 appears zero times,
unique among FUT deserializers) and parses only itemData -> dreamSquads.
* class -> deserializer resolution: the name literal is preceded by a 4-BYTE
HEADER and the factory LEA points at the header, so look up name_addr - 4.
Six attempts failed on this; now ghidra_env.class_deser(). Unlocked 11 SBC/
Draft schemas.
* live-only endpoints the request table never lists: ut/%s/squad/list,
ut/%s/user/club, ut/%s/club/stats/*, ut/%s/clientdata/<key>. The template
table is a floor, not a ceiling -- the log is the only ground truth.
* 163 RS4 call names exist; we served 17. All now served.
FIXED: club/stats/* was answering with the entire 28-item club inventory on every
poll (it fell through to the generic /club route).
UNSOLVED: the pack reveal's "Send to Club" (PUT ut/%s/item) kills the FUT session
whatever we answer -- {} included -- while its sibling quick-sell endpoint accepts
a bare {}. Seven hypotheses eliminated by live test, documented in
REBUILD_RESEARCH.md S14c so none get re-walked. FUT_PACK_AUTOCLUB routes around it.
Also unfixed: store tiles render "unknown" (displayGroup is parsed RECURSIVELY by
the same element parser; sending it FROZE the store, so FUT_STORE_GROUPS=1 is
default off).
Tests: test_fut_contract.py 380 (live, read-only) + test_match_rewards.py 51 (pure).
Note: fut_store.py carries some pre-existing uncommitted changes from before this
session (pack catalogue ids, pending-pile behaviour) that could not be separated
from this session's additions in the same file.

The client now issues PUT /squad and the hub renders coins, record and the
squad roster. Three separate root causes, all verified live.
Squad blocker (the long-standing "client never sends PUT /squad"):
AddPlayerToSquad, GetSquads and SelectSquadById issue ZERO network requests
(pure local model reads/mutations, FutSquadServiceImpl vtable 0x180233ff0);
only SaveCurrentSquad writes, and it is unguarded. The client simply needed a
populated ACTIVE squad model, which arrives via the massinfo `squad` member.
No response of ours was ever being rejected.
userMassInfo is NOT required to be {}:
0x180174630 is a FLAT {userInfo, squad, settings, userData} body -- the old
"wrapper key is user" note was wrong, and the historical freeze was the
malformed squad member, not the envelope.
clubNameChangeAllowed must be false:
sending true advertises a club-rename flow whose UI model is never populated;
the client shows a naming prompt and dies confirming it (ACCESS_VIOLATION
reading 0x0 at FIFA17.exe+0x71b8651, 4/4 runs, no CardsDLL frame and no request
in flight). Isolated by a single-variable run; guarded by a contract check.
Endpoint/schema corrections found in live traffic, invisible to static analysis:
* GET ut/%s/squad/list is a real endpoint and must return {"squad":[...]},
not the active-squad object (the /list suffix is appended by the caller, so
it never appeared in the request table)
* PUT lands on ut/%s/squad/<id>, not a bare ut/%s/squad
* userInfo currencies are read as name/funds/finalFunds/active -- there is no
"value" key, so coins always rendered 0
* squad-list elements take STRING formation/squadType, not ints
* the CardsDLL script-API thunk<->name table was off by one (AddPlayerToSquad
is 0x18004aa70; 0x18004aff0 is GetPotentialChemistry_Club)
FUT_MASSINFO / FUT_USERINFO ladders keep every step of the bisect reproducible.
Contract suite 311 -> 358 checks. Tooling added: PyGhidra harness (Ghidra's
Java/OSGi script path is broken on this box), minidump reader, live code grabber.

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.
