The bug we just closed was invisible to every existing check: PUT /item answered 200
with a well-formed JSON body, and the body told the client the move had FAILED. Seven
attempts, weeks of investigation, and nothing in the suite would have noticed a
regression back to {}.
test_move_verdict_shape asserts the record vector exists, has ONE RECORD PER REQUESTED
ITEM (an empty vector fails the client exactly as hard as a wrong field), and that
id/pile/success carry the number/string/bool types their getters require.
Non-mutating: it asks to move ids that cannot exist, so nothing changes pile. The
verdicts come back success=false, which is honest and is not what is asserted.
Verified it actually catches the regression rather than just passing:
default (ack) 392 checks passed, 0 failed
FUT_MOVE_BODY=empty 382 passed, 1 FAILED -- "returns itemData array"

test_fut_contract.py no longer imports ACCOUNT from fut_account. The expected
persona comes from FUT_TEST_PERSONA_ID and the target from FUT_TEST_BASE, so the
suite now imports nothing but stdlib and talks to a server at a URL.
That is what lets these 380 checks certify ANY implementation of the reversed
spec, a future Rust openfut-core included, without replaying the reverse
engineering. The original reason for reading ACCOUNT still holds and is preserved
in the comment: suite and server must not each hold a private copy of the
constant, or the identity-consistency checks would only prove two copies matched.
Also adds pileSizeClientData(0x227) behind FUT_PILESIZES (default off). A probe
run with 16 uniquely-valued entries did NOT move the MY CLUB counter, so that
member is eliminated as its source; the code is kept for the record and flagged
off.
Docs: OPENFUT_PROJECT_REPORT.md and OPENFUT_HANDOFF.md. The report now separates
"built but untested" from "never requested by the client" -- the server log records
User-Agent, and splitting real client traffic (ProtoHttp) from this project's own
probes shows /season, /tournament, /champion, /match, /clubUser and /user/list are
at ZERO client requests. /clubUser (0 client, 93 probe) and /user/list (0 client,
180 probe) are the starkest: work was done on both assuming the client wanted them.

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.

Serve 18 real-player auctions on GET auctionhouse (search) built to the reversed
auction record schema (deser 0x18013e410) field-for-field: itemData reuses
fut_store._item (the proven club/squad card parser 0x18013fe00), scalar fields
all HIGH-confidence reversed. Rating-based buy-now pricing; tradeId space
900000000+. tradePile/watchList stay empty (no live sell/watch flow yet). Toggle
off with FUT_MARKET=empty.
Extend test_fut_contract.py to validate EVERY populated record field type
(numbers/strings/bool/object) so the listings are proven freeze-safe OFFLINE
before the game parses them. 311 checks, all passing.

Add tools/test_fut_contract.py -- stdlib-only, read-only tests that hit the live
utas_server and assert each response matches the shape reversed from CardsDLL
(docs/ENDPOINT_MAP.md). Encodes freeze-safety invariants (auctionInfo/players/
itemData/currencies/purchase must be array/object per the SAX deserializers;
scalar-where-container = busy-loop freeze at 0x1801c7f1a) plus the specific
contracts: v2/store gate == SUCCESS, coin counter binds currencies[coins].funds,
userMassInfo stays {}, empty squad slots carry itemData=null (proven-safe).
Catches the regression class that previously bit us (phantom packs, coins-0,
squad reset). 58 checks, all passing.
