FIFA 17 FUT — Complete Endpoint Map (clean-room)

Status: 2026-08-02. Derived entirely from binaries we own (CardsDLL_Win64_retail.dll, image base 0x180000000) plus our own running client. No leaked EA source used.

This is the spec for rebuilding FIFA 17 Ultimate Team fully offline (and the Rosetta for porting to FIFA 23). It maps the complete FUT API surface — ~100 FutXServerResponse types the client can parse — with field-level detail for every endpoint, prioritizing the core playable loop. Target: port into Rust openfut-core behind a FIFA-17 bridge.

How this was produced (methodology)

• Master atom dictionary: dumped the name table at 0x1802d2760 straight from the DLL → 907 atoms (atom int → JSON key name). Every SAX deserializer dispatches on these. Table extractor: tools/atomdump.py (regenerable); output atoms.tsv.
• Deserializer locator (RECIPE): struct-name string → VA = 0x1801e5000 + (fileoff − 0x1e4400) → .text lea r8 xref → the response object's vtable (deserializer at vtable slot +0x08) → walk the atom cmp/sub/dec+je ladder → translate atoms via atoms.tsv → classify each field by the leaf getter it calls.
• Parser internals (shared by ALL responses): key → FNV-1a (0x180180d00, seed 0x811c9dc5) → atom → jump-table dispatch; unknown atom → value-SKIP 0x180135ff0 (extra/unknown keys are always safe). Leaf getters: int/num 0x1801c79d0, bool 0x1801c7620, string 0x1801c7aa0. Type fidelity is mandatory: feeding a scalar getter an object/array desyncs the SAX reader → infinite tokenizer spin (freeze at 0x1801c7f1a). Freeze-risk (must-be-object/array) fields are flagged per struct below.
• Ladder caveat: atom dispatch is a jump-ladder of running-sum sub/dec chains — the real atom is the accumulated sum, not the raw immediate. Field schemas are HIGH confidence; HTTP verbs are often inferred (the verb table isn't statically recoverable) — LOW confidence unless corroborated by /tmp/utas_server.log.

Reversal coverage (7 feature groups, ~100 structs)

Group	Structs	Fully reversed	Section
Transfer Market / Auction House	12	9	Transfer Market
Squad Building Challenges (SBC)	8	5	SBC
FUT Draft	7	5	Draft
Match / Seasons / Tournaments	19	9	Seasons
Club / Cards / Consumables	16	15	Club
Store / Packs / Purchases	6	5	Store
User / Hub / Settings / Objectives / LB	32	7 deep + 11 partial	User

"Fully reversed" = top-level field schema + types decoded HIGH-confidence. Nested card/squad elements reuse the shared item (0x18013fe00) / squad (0x18013d1f0) parsers documented in CARD_SYSTEM.md. Every struct in the sections has its deserializer VA, key list, and a minimal known-good JSON — including ack-only ({}) responses.

Shared record parsers (reused across groups)

VA	Record	Used by
0x18013fe00	ITEM / card element (itemData)	club, squad, packs, purchased, market, draft, SBC
0x18013d1f0	full SQUAD object	squad, draft, SBC squad-challenge
0x18013e410	auction/trade record (auctionInfo[] element)	market search/watch/tradepile
0x18013e7f0	IS-list body {auctionInfo,credits,total,duplicateItemIdList}	market
0x180135ff0	value-SKIP (unknown keys)	all

★ Highest-value findings (actionable now)

1. Store "not available" — the ut/v2/store eligibility gate. FutStorePackQuantitiesServerResponse (deser 0x1801758c0) reads exactly one key result (atom 0x288) → must be {"result":"SUCCESS"} (other enum values gate the store closed: TOO_MANY_TOURNAMENTS/LOCKED_PERMANENT/LOCKED_RETRY/LOCKED_TROPHIES). Pair with the Blaze purchase flags + the >1024×768 GetSystemMetrics resolution check. See Store §.
2. Match rewards live in FutDestroyMatchServerResponse (0x180121b60), NOT FutPlayGame (ack-only). Coin fields at struct offsets 0x28–0x48: allCoins/matchCoins/seasonCoins/ tournamentCoins/coins/boostConis(sic)/participationAward. See Seasons §.
3. GetClubInfo returns user (club-user stat array), not itemData. Rendered cards come from FutViewCardsServerResponse (0x1801293d0) on ut/%s/item — explains why the current /club itemData is SKIP'd yet cards still render. See Club §.
4. SBC requirements = generic {eligibilityKey,eligibilityOperation,eligibilityValue} triples in an elgReq array — the key to modding challenges. See SBC §.
5. Objectives = ManagerQuests, client-driven with no ServerResponse struct / no route; gated by enableObjectives in settings. See User §.

Catalog corrections to the current backend (utas_server.py / fut_store.py)

• Store extPrice inner keys are amount/currency, not mtx; pack identity is assetId (0x23), not id (harmless SKIPs otherwise).
• ut/v2/store must return {"result":"SUCCESS"} (currently unhandled → contributes to store error).
• GetUserMassInfo top-level wrapper key is user — WRONG, corrected 2026-08-03. The body is FLAT: userInfo(0x370)/squad(0x2cd)/settings(0x2bf)/userData(0x36d) are top-level keys. user(0x36c) only appears nested inside clubUser. Now served populated.
• No-op deserializers (bare ret) where {} always suffices: ChangeClubName, ActivateCard, SignLoanPlayer, and most ack responses.

The 12 response structs

All 12 are GAPs — utas_server.py currently has no auctionhouse / trade / tradePile / watchList / marketdata routes. The nested itemData card is the one piece already served (by the existing /club + item_def machinery in utas_server.py), so it can be reused verbatim inside these responses.

Freeze-risk summary (type fidelity is mandatory)

• auctionInfo → array (never object/scalar).
• itemData inside each record → object (the card; reuse item_def).
• duplicateItemIdList → array.
• bidState, tradeState, sellerName → strings.
• credits, total, count, *Price, *Bid, expires, tradeId → numbers.
• watched → bool. Any scalar fed where an object/array is expected desyncs the tokenizer → hard busy-loop freeze at 0x1801c7f1a (same failure mode documented for userMassInfo/squad in CARD_SYSTEM.md).

Implementation notes for utas_server.py

• Add routes (all currently missing): GET /auctionhouse (search + count), POST /auctionhouse (start), PUT /auctionhouse/relist, GET/POST /trade, GET /tradePile, GET/PUT /watchList, GET /marketdata, DELETE (ut/delete)/trade, DELETE (ut/delete)/watchList.
• Every list response shares one builder: {auctionInfo, credits, total}.
• <record>.itemData = exactly the object returned by item_def(rid).
• Ack endpoints (5,7,8,10) can safely return {} (bodies are non-keyed/ack).

Squad Building Challenges (SBC)

Reversed from FIFA17 cardsdll.dll (base 0x180000000) using the deserializer-reversal recipe: struct name → .rdata VA → .text xref (lea r8) → deserializer function → atom cmp/sub/dec ladder + jump-table → atoms.tsv key names → leaf getter type. Getter fingerprints: 0x1801c7aa0=string, 0x1801c79d0=int/number, 0x1801c7620=bool, 0x180008120=fixed-buffer string-copy (string), 0x180135ff0=value-SKIP (safe unknown key), peek+loop via 0x1801c7f10/0x1801369f0/0x18015a750=nested object/array.

Endpoint family: ut/%s/sbs (%s = game/fifa17), base string @ fileoff 0x21d908. The baseline utas_server.py has no sbs* routes at all → every endpoint below is a GAP.

1. FutLoadSetChallengesResponse — CONFIDENCE: HIGH ✅ fully reversed

Deserializer dispatch @ 0x18017bbbb (key-iter call 0x180141ee0); wrapper/ctor 0x18017b9ed. Parses an array of flat SET+CHALLENGE records (each record carries both set-level and challenge-level fields). Low atoms via cmp r8d/sub ladder; high atoms (0x280–0x354) via byte+dword jump table at 0x18017c334/0x18017c310 (decoded from binary).

3. FutSBCStartChallengeResponse / squadChallenge record — CONFIDENCE: HIGH ✅ fully reversed

Dispatch @ 0x180155949; ctor 0x18015531d. Method+path: POST sbs/challenge/{challengeId}. Returns the squadChallenge record (the working squad for a challenge). This same record parser is shared by FutLoadSetTypesServerResponse.

{"id":1}

6. FutLoadSetTypesServerResponse — CONFIDENCE: MEDIUM ⚠️ partial

Dispatch @ 0x180154d69; ctor 0x18015469d. Method+path: GET sbs/challenge/{challengeId}/squad. Parses an array of squadChallenge templates ("set types" = squad-building slot templates), same key set as the squadChallenge record: {challengeId(0x074), index(0x163), playerType(0x23d str), playerRequirements(0x237 nested), squad(0x2cd nested)}. Outer top-level wrapper (array framing at 0x180154a2d) is callback-driven; exact top-level envelope key not resolved.

[{"challengeId":1,"index":0,"playerType":"","playerRequirements":[],"squad":[]}]

7. FutSBCSetDataServerResponse — CONFIDENCE: LOW-MEDIUM ⚠️ partial

Dispatch @ 0x18016ff2a; ctor 0x18016fa7d. Method+path: GET sbs/sets (set-data / by category). Top-level is a callback array-parser (lea r8,[rsi+0x50] vector-append at 0x18016fb5e) that appends set records parsed by the shared flat set-record deserializer; only one top-level scalar was resolved:

key	atom	type
reset	0x283	bool
(set records)	—	nested array; each element has the SET-level fields (setId, name, description, awards, repeatable, endTime, challenges, starRating, setImageId, timesCompleted, sortPriority) — reuse struct #1's field vocabulary

{"reset":false,"sets":[{"setId":1,"name":"League Basics","description":"",
  "repeatable":false,"endTime":0,"awards":[],"challenges":[]}]}

8. FutSBCTagSetsServerResponse — CONFIDENCE: LOW-MEDIUM ⚠️ partial

Ctor 0x18015405d; deserializer is a callback-based array parser (installs per-element handler 0x180154280, vector-append) rather than an atom cmp ladder — no scalar keys resolved from the dispatch. Semantically it acknowledges a set-tag operation and returns the updated tagged sets. Method+path: POST/PUT sbs/sets/tag.

{"sets":[]}

Shared record shapes

elgReq — the SBC requirement/constraint list (the tricky part; parsed in struct #1 @ 0x18017bd9d, vector at [rdi+0x358]). Array of constraint objects, inner dispatch @ 0x18017bde0:

key	atom	type
eligibilityKey	0x0f2	int (constraint selector)
eligibilitySlot	0x0f4	int/bool
eligibilityValue	0x0f5	int (target value)
eligibilityOperation	0x0f3	int (comparator; skip-handled here)
eligibilities	0x0f1	(container atom)

Chemistry/rating/nation/league-count constraints (teamChemistry 0x307, starRating 0x2e2, sameNationCount 0x297, sameLeagueCount 0x296, sameClubCount 0x295, nationCount 0x1d4, leagueCount 0x18c, clubCount 0x8b, playerCount 0x22f, chemistry 0x81) are encoded generically as {eligibilityKey, eligibilityOperation, eligibilityValue} triples, not as named scalar fields on the record. FREEZE-RISK: elgReq must be a JSON array of objects.

awards / grantedAwards — nested array of reward objects (atoms: rewardType 0x28e, rewardValue 0x28f, rewardQuantity 0x28d, rewardMultiplier 0x28c, awardCount 0x40, awardSet 0x45, awardSetId 0x46, prizeSet 0x253). FREEZE-RISK: must be array.

SET-level field vocabulary (available atoms for a full set record): setId 0x2bc, name 0x1d0, description 0x0d1, challenges 0x76, challengesCount 0x78, challengesCompletedCount 0x77, repeatable 0x280, endTime 0x106, awardSet 0x45, setImageId 0x2bd, starRating 0x2e2, sortPriority 0x2cb, timesCompleted 0x322, categoryId 0x73, priority 0x250.

Freeze-risk summary (type fidelity mandatory)

• formation = string (e.g. "f442"), never int.
• awards, elgReq, squad, playerRequirements, grantedChallengeAwards, grantedSetAwards, sets, challenges = arrays/objects, never scalar. Feeding a scalar getter an object/array desyncs the SAX reader → tokenizer spin (freeze at 0x1801c7f1a).
• Unknown/extra keys are safe (value-SKIP handler 0x180135ff0).

FUT Draft

Clean-room reverse of the FIFA 17 CardsDLL (base 0x180000000) FUT Draft response deserializers. Method: located each RS4:Fut*DraftServerResponse name string, computed its .rdata VA, found the .text factory (lea r8,[name]), then read the adjacent JSON deserializer's atom dispatch (FNV key → atom → getter). Atoms translated via atoms.tsv. All 7 endpoints are a total GAP — tools/utas_server.py has zero draft routes today.

Endpoint family: ut/%s/draft/mode (+ sub-paths below), %s = "game/fifa17".

Shared sub-deserializers used by Draft:

• 0x18013fe00 — ITEM/card element deser (a full player card, same schema as club/squad itemData; see CARD_SYSTEM.md). Must be a JSON object.
• 0x18013d1f0 — SQUAD deser (the whole squad model: formation, players[].itemData, manager, custom, kicktakers…; identical to GET /squad/0 LoadActiveSquad). Must be a JSON object.

Leaf getters: int/num 0x1801c79d0, bool 0x1801c7620, string 0x1801c7aa0; unknown-key SKIP 0x180135ff0 (extra keys are safe). Feeding a scalar getter an object/array desyncs the SAX reader → tokenizer freeze — so every field flagged [freeze-risk] below MUST be emitted as the right container type (or omitted entirely).

1. FutGetDraftChoicesServerResponse — CONFIDENCE: HIGH (fully reversed, incl. deep choice record)

• Struct name .rdata 0x180225ea0; factory 0x18014f250; deserializer 0x18014f2d0.
• Method/Path: GET ut/game/fifa17/{champId}/draft (path fragment "/%d/draft" @0x2252c8). Returns the choices offered for the current pick.
• Top-level keys (ordered):

  key	atom	type	notes
  choices	0x83	array [freeze-risk]	array of choice records (below) → vec@+0x30
  positionid	0x244	int	@+0x28
  tier	0x315	int	@+0x2c

• Choice record (each element of choices, element size 0x20; sub-dispatch @0x18014f44c):

  key	atom	type	notes
  formation	0x12b	string	formation-choice rounds (e.g. "f442"); parsed str→id
  index	0x163	int (byte)	choice slot index 0..n → byte@+0x28
  itemData	0x16b	object [freeze-risk]	the offered player card, parsed by ITEM deser 0x18013fe00
  So a pick round is either a formation round (choices carry formation) or a player round (choices carry itemData + index), with the round's slot given by top-level positionid and tier.

• MINIMAL known-good (player round, 5 choices for one position):

{"positionid":0,"tier":1,
 "choices":[
   {"index":0,"itemData":{"id":1000001,"resourceId":20801,"assetId":20801,"itemType":"player","rating":94,"preferredPosition":"ST","nation":38,"teamid":243,"leagueId":53,"rareflag":1,"untradeable":true,"attributeList":[{"index":0,"value":90}],"itemState":"free","owners":1,"contract":7,"fitness":99}}
 ]}

Formation round: {"positionid":0,"tier":1,"choices":[{"index":0,"formation":"f442"},{"index":1,"formation":"f433"}]}.

---

2. FutGetDraftCurrentStateServerResponse — CONFIDENCE: HIGH (fully reversed, incl. roundsInfo element + squad delegation)

• Struct name 0x180224200; factory 0x180146cc0; deserializer 0x180147070 (begin-obj @0x1801470f2, dispatch @0x18014715c).
• Method/Path: GET ut/game/fifa17/squad/mode/draft/state?mode=ONLINE | ?mode=SINGLE_PLAYER. CORRECTED 2026-08-04 from a LIVE CAPTURE. The path above previously omitted the squad/mode segment. The real URL is ut/%s/squad/mode (template @0x18021e7f8) with /draft/state appended, which is why it is invisible to the request-template table and why the generic /squad route swallowed it. The suffix is appended to a caller-supplied buffer by FUN_180146ac0, which has no resolvable callers, so the full path is established by the capture in REBUILD_RESEARCH.md §15, NOT statically.
• Top-level keys:

  key	atom	type	notes
  squad	0x2cd	object [freeze-risk]	drafted squad, SQUAD deser 0x18013d1f0
  entranceCriteria	0x108	object [freeze-risk]	nested object (safe to omit)
  gamesWonCurrentMatch	0x13b	int	@+0x60
  roundsInfo	0x293	array [freeze-risk]	array of round records (below), elem deser 0x180146eb0, elem size 0x20 → vec@+0x80
  squadState	0x2d5	string	e.g. "DRAFTSQUAD_ON"
  stateParam1	0x2ee	string→enum	@+0x5c (default 5)
  stateParam2	0x2ef	string→int	@+0x64

• Round record (roundsInfo[], all scalar; deser 0x180146eb0): round(0x290,int@+0xc), score(0x29a,int@+0x10), opponentScore(0x200,int@+0x14), penaltyScore(0x217,int@+0x18), opponentPenaltyScore(0x1fd,int@+0x1c), opponentId(0x1fc,int/long@+0x0), difficulty(0xd4,string enum@+0x8). (score and penaltyScore offsets were SWAPPED here until 2026-08-04.)
• THE ROOT CONTAINER IS A JSON ARRAY. 0x180147070 initialises, discards two tokens, then tests if (t3 != 0xd) around a do { ... } while (t != 0xd) element loop. Handed a top-level OBJECT it never reaches its exit condition and spins in the inner while (t != 10) loop while the tokenizer returns EOF forever: process alive, no crash dump, no dialog. That is the hang observed live on 2026-08-03.
• The body previously printed here was a HANG RECIPE and is replaced below. It was object-root, it used the spelling DRAFTSQUAD_ON which is NOT an accepted value of the squadState enum, and it embedded a full squad object. Anyone who served it would have reproduced the exact freeze this entry was supposed to help avoid.
• MINIMAL known-good (verified: two agents independently walked this body through the deserializer token by token to a clean exit in 16 reads):

[{"squadState":"INVALID","stateParam1":"INVALID","stateParam2":"0","gamesWonCurrentMatch":0,"roundsInfo":[]}]

squad(0x2cd) and entranceCriteria(0x108) are OMITTED and omission is provably inert: FUN_180135ff0 is called from both defaults, so unknown keys are skipped. entranceCriteria's shape is now known anyway (an object of three int keys COINS / DRAFT_TOKEN / POINTS) but knowing a shape is not a reason to send it. stateParam2 may be a JSON number or a string; the string getter stringifies token types 2/3/4, so "0" is correct but not mandatory. Served today behind FUT_DRAFT_STATE (default on) in utas_server.py.

3. FutGetDraftStatsServerResponse — CONFIDENCE: HIGH (all fields scalar; no freeze-risk)

• Struct name 0x180226540; factory 0x18015076d; deserializer 0x1801508c0 (begin-obj @0x18015093b, dispatch @0x1801509bc).
• Method/Path: GET ut/game/fifa17/draft/mode (GetDraftStats RPC; historical/aggregate draft stats).
• Keys (all int, except draftChampion bool): gamesWon(0x13a), gamesLost(0x138), scoredGoals(0x29b), concededGoals(0xa1), bestBuilderScore(0x52), draftChampion(0xe1, bool), draftsCompleted(0xe2), passAccuracyTotal(0x212), possessionPercentage(0x247), possessionTotal(0x249).
• MINIMAL known-good:

{"gamesWon":0,"gamesLost":0,"scoredGoals":0,"concededGoals":0,"bestBuilderScore":0,"draftChampion":false,"draftsCompleted":0,"passAccuracyTotal":0,"possessionPercentage":0,"possessionTotal":0}

---

4. FutGetDraftAwardServerResponse — CONFIDENCE: HIGH (fully reversed)

• Struct name 0x1802266f8; factory 0x18015106c; deserializer 0x1801510c0 (begin-obj @0x180151129, dispatch @0x1801511ac).
• Method/Path: GET/POST ut/game/fifa17/draft/mode (GetDraftAward — claim/return the draft prize).
• Keys:

  key	atom	type	notes
  item	0x16a	array [freeze-risk]	awarded item cards, ITEM deser 0x18013fe00 (loops)
  halId	0x150	int	@ (prize/hal id)
  type	0x354	int	prize type code
  value	0x377	int	prize value (e.g. coins)

• ROOT CONTAINER: ARRAY, not object. CORRECTED 2026-08-04. 0x1801510c0 has the same array-root prologue as FutGetDraftCurrentState. The object-root body that used to be printed here would hang the client identically, and it was sitting in this file labelled "known-good".
• MINIMAL (root shape corrected; the key set itself is unchanged and was not re-verified this pass, so TODO/CONFIRM the members before serving):

[{"type":1,"value":15000,"halId":0,"item":[]}]

With an item prize: "item":[{ …full card object as in itemData… }].

• Why both of these were wrong at once: a census claimed only three array-root readers existed in the DLL. It missed this one. A second census, run to check the first, was wrong in the opposite direction. Roughly 23 of 86 top-level readers remain unclassified. Do not serve any endpoint in this document until its root container has been classified by reading the actual prologue, not by regex.

---

5. FutPickDraftChoiceServerResponse — CONFIDENCE: MEDIUM (empty-ack, inferred)

• Struct name 0x180226078; factory 0x18014fba0. The factory installs the generic base ServerResponse vtable 0x18022cb58 (shared by dozens of structs) — i.e. no struct-specific deserializer / no parsed fields. The neighboring 0x18014fcb0 is the request serializer, not a response reader.
• Method/Path: PUT/POST ut/game/fifa17/{champId}/draft/choose and ut/game/fifa17/draft/choose/difficulty (fragments @0x2254c0 / 0x2254a0). Commits one pick (or the difficulty choice).
• Body: an empty ack — the client re-reads state via GetDraftCurrentState / GetDraftChoices afterward.
• MINIMAL known-good: {}

---

6. FutPickDraftAutoChoiceServerResponse — CONFIDENCE: HIGH (delegates to squad deser)

• Struct name 0x180226208; factory 0x18014fd80; deserializer 0x18014fdf0. The body is parsed by a single call to the SQUAD deser 0x18013d1f0 (@0x18014fe82) into the struct's squad member.
• Method/Path: POST ut/game/fifa17/{champId}/draft/autocomplete (fragment @0x225638). Auto-fills the remaining picks and returns the completed squad.
• Body: a squad object [freeze-risk] (same schema as GET /squad/0).
• MINIMAL known-good:

{"id":0,"personaId":0,"formation":"f442","squadType":"REGULAR_SQUAD","chemistry":100,"starRating":5,"captain":0,"changed":0,"manager":[],"actives":[],"players":[{"index":0,"kitNumber":0}],"kicktakers":[]}

(Emit a fully-populated players[].itemData for a real auto-drafted XI.)

---

7. FutPurchaseDraftModeServerResponse — CONFIDENCE: MEDIUM-HIGH (field set fully reversed; response-variant ambiguity)

• Struct name 0x180224fb0; factory 0x18014c0bd; deserializer 0x18014c260 (begin-obj @0x18014c2d5, dispatch @0x18014c3bb).
• Method/Path: POST ut/game/fifa17/purchase/mode/{price}/draft (fragment @0x2257a8). Buys entry into draft mode; returns the fresh draft session summary.
• Keys (all scalar int): championEventId(0x7b), expectedTierLevel(0x115), gamesPlayed(0x139), gamesRemaining(0x13c), rank(0x26d), score(0x29a), tierLevel(0x317).
• Note: a second, larger struct (size 0x38, deser @0x180150379, factory @0x18015028d) also references this name string. It carries no visible scalar field ladder and is likely an alternate/summary envelope; the 0x18014c260 field-parser above is treated as authoritative. Confirming which body the live client reads is the remaining gap.
• MINIMAL known-good:

{"championEventId":0,"expectedTierLevel":1,"gamesPlayed":0,"gamesRemaining":4,"rank":0,"score":0,"tierLevel":1}

---

Implementation notes for utas_server.py

• Add routes under G + r"/draft": GET …/draft/state, GET …/{id}/draft, POST …/{id}/draft/choose, POST …/draft/choose/difficulty, POST …/{id}/draft/autocomplete, POST …/purchase/mode/{n}/draft, plus GetDraftStats / GetDraftAward on …/draft/mode.
• Reuse the existing squad/item JSON builders (fut_seed.player_item, _base_squad) for squad, itemData, item[] — those objects are already known-good through deser 0x18013d1f0 / 0x18013fe00.
• Freeze-risk containers to never send as scalars: choices, choices[].itemData, squad, entranceCriteria, roundsInfo, item, and the PickAutoChoice squad body.

Match / Seasons / Tournaments

Reversed from cardsdll.dll (base 0x180000000) per RECIPE.md. CardsDLL base 0x180000000. Parser shared internals: each JSON key → FNV-1a → atom int; deserializer dispatches on atom via cmp/sub/dec + je binary tree. Unknown atoms are routed to the container-aware SKIP handler 0x180135ff0 — extra keys are SAFE. Leaf getters: int 0x1801c79d0, bool 0x1801c7620, str 0x1801c7aa0. Nested object/array = call to a sub-deserializer or array loop. Feeding a scalar getter an object/array desyncs the SAX reader → infinite spin freeze at 0x1801c7f1a.

SAX token-type constants seen in every loop (NOT keys, ignore): atom 6 (= end-object token), atom 10 (end-array/container token). Atom values > 906 in a raw dump are jump-table offsets, not atoms.

Key-spelling caveat: the wire key is FNV-hashed, so JSON keys must match EA's exact spelling incl. typos — notably boostConis (atom 96, not "boostCoins") and matchCoinMultipliers.

Two response families found

1. Bespoke deserializer (custom atom switch) — most Season/Match/Tournament load/list responses.
2. Ack-only / base-response — FutMatchReady, FutPlayGame, FutUpdateSeason, FutUpdateFriendlySeason, FutGetStoryModeReward. Their factory allocates a 0x28-byte object and calls only the base ServerResponse constructor 0x18011f850 (sets vtable 0x18022cb58, timeout 0x7530, status -1). They parse NO body fields → the client accepts any body incl. {}. The match reward/coins are NOT in FutPlayGame — they are carried by FutDestroyMatch.

HTTP method/path note

Endpoint path strings live in an .rdata string-pool (pointer table at fileoff 0x21d480), not lea-referenced from code, and the request-descriptor table carries the verb in a parallel array that is not statically recoverable here. Methods below are inferred from REST/UTAS semantics — confidence LOW on method, HIGH on struct fields. Path templates (verified in binary, %s="game/fifa17"): ut/%s/match, ut/%s/season, ut/%s/season/user, ut/%s/season/%s/user, ut/%s/season/%s/reset, ut/%s/season/friendly, ut/%s/tournament, ut/%s/tournament/user, ut/delete/%s/tournament/user, /season/user/history.

Baseline (utas_server.py) status

All of these are currently GAP / stubbed: /season → (200, {}), /match/keepalive → (204). No match/season/tournament body is currently reversed in the baseline.

HIGHEST VALUE — MATCH RESULT / REWARD RECORD

FutDestroyMatchServerResponse — the post-match coin/credit reward record ★CONFIDENCE: HIGH

• Deserializer VA: 0x180121b60 (factory 0x180121700, name-lea 0x18012170c)

• Method+path (inferred): DELETE ut/game/fifa17/match/{matchId} — closes the match and returns the credited rewards. This is where a completed match reports its coin/XP award. Score/win-loss are NOT here — the client SENDS the result in the request; the server RESPONDS with the coins.

• Ordered reward fields (all int unless noted; offsets in the parsed struct):

  atom	key	type	offset	notes
  20	allCoins	int	0x28	new total coin balance
  436	matchCoins	int	0x2c	coins awarded for this match
  809	tournamentCoins	int	0x30
  776	teamOfTournamentWinner	bool	0x34
  670	seasonCoins	int	0x38
  149	coins	int	0x3c	reward amount (this txn)
  529	participationAward	int	0x44
  96	boostConis	int	0x48	(EA typo — exact key)
  617	qualifiedChampionEventId	int	0xb0
  310	gameModeAward	nested	—	object, SKIP-safe
  437	matchCoinMultipliers	nested	—	array/object, SKIP-safe
  619/805/852/887	quantity/total/type/value	nested item	—	reward-item sub-object fields (prize list element; type is str)
  877	userData	nested	via 0x180142470	user snapshot object (FREEZE-RISK: must be object)

• Coin fields cluster tightly at 0x28–0x48, confirming a coherent credits struct. All top-level coin fields are scalar int → safe.

• MINIMAL known-good JSON (scalars only, zero freeze risk):

{
  "coins": 400,
  "allCoins": 15400,
  "matchCoins": 400,
  "seasonCoins": 0,
  "tournamentCoins": 0,
  "boostConis": 0,
  "participationAward": 0,
  "qualifiedChampionEventId": 0,
  "teamOfTournamentWinner": false
}

• GAP (baseline has no match reward body).

SINGLE-PLAYER PLAYABLE LOOP

FutCreateMatchServerResponse ★CONFIDENCE: HIGH

• Deserializer VA: 0x180120380 (name-lea 0x18011ffbd)
• Method+path (inferred): POST ut/game/fifa17/match — creates the match, returns match/squad info.
• Fields:

  atom	key	type	offset	notes
  740	startDateTime	int	0x28	epoch
  641	reportIdEnabled	bool	—
  717	squad	nested (0x18011a830)	—	squad/ITEM array — FREEZE-RISK (must be array)

• MINIMAL JSON: {"startDateTime": 1580000000, "reportIdEnabled": false} (omit squad — SKIP-safe)
• GAP.

FutMatchReadyServerResponse ★CONFIDENCE: HIGH (ack-only)

• Deserializer: none — factory 0x180120810 → base ctor 0x18011f850 only (name 0x18021d380).
• Method+path (inferred): PUT ut/game/fifa17/match/{matchId} (mark ready).
• Parses no fields. MINIMAL JSON: {}. GAP.

FutPlayGameServerResponse ★CONFIDENCE: HIGH (ack-only)

• Deserializer: none — factory 0x180162170 → base ctor 0x18011f850 only (name 0x180228050).
• Method+path (inferred): POST ut/game/fifa17/match/{matchId} (submit game result; body carries score/stats client→server). Response body is ignored by the client. Rewards arrive via DestroyMatch.
• MINIMAL JSON: {}. GAP.

FutResetMatchServerResponse ★CONFIDENCE: HIGH

• Deserializer VA: 0x18016fd10 (name-lea 0x18016fccd)
• Method+path (inferred): POST ut/game/fifa17/season/{seasonId}/reset.
• Fields: atom 643 reset = bool @0x28.
• MINIMAL JSON: {"reset": true}. GAP.

FutSeasonListServerResponse ★CONFIDENCE: HIGH (root shape CORRECTED 2026-08-04)

• Deserializer VA: 0x1801683f0. The previously documented 0x180167740 is the per-ELEMENT parser, not the response deserializer.
• THE ROOT IS AN OBJECT WITH ONE KEY. 0x1801683f0 runs a key loop and matches exactly one atom, seasons(0x2ad); the array opens only inside it. This entry previously described an array root, because someone read the element parser and documented its key set at the document level. A bare array populates nothing, and utas_server.py served one for months on the strength of this row.
• Method+path: GET ut/game/fifa17/season.
• Element ordering matters: type MUST precede divisionId, because the divisionId branch reads the already-parsed type field at elem+0x1b4.
• Element stride is 0x318. (0x1f8, recorded elsewhere, is the offset of the compared short WITHIN an element.) The short the online path matches on is written from divisionId as (0xb - divisionId), not from id.
• eligibilityKey/eligibilitySlot/eligibilityValue below are inner members of elgReq and are inert at element level, so the old minimal body was wrong twice.
• Element fields:

  atom	key	type	notes
  348	id	int	season/division id
  220	divisionId	int
  242	eligibilityKey	int
  244	eligibilitySlot	int
  245	eligibilityValue	int
  246	elgOperation	str
  247	elgReq	nested	SKIP-safe
  595	prizeSet	nested	array — FREEZE-RISK

• MINIMAL JSON (object root, single seasons key):

{"seasons":[{"type":"OFFLINE","id":1,"divisionId":10}]}

prizeSet(0x253), elgReq(0xf7) and matches(0x1b8) are all while (tok != 0xd) ARRAY loops: a scalar in any of them is the 0x1801c7f1a spin. Omit all three. Semantic hazard: omitting untilEndSeconds makes the season end timestamp equal now.

• Do not serve this yet. Across 486 real client requests (User-Agent ProtoHttp, roughly 30 boots) the game has never requested /season. Every /season line in /tmp/utas_server.log is our own curl or Python-urllib. Serving a body here changes nothing observable until something upstream makes the client ask.
• GAP. (Note: root JSON shape is an array/object wrapper — verify container before shipping.)

FutSeasonLoadDataServerResponse ★CONFIDENCE: HIGH (fully traced switch)

• Deserializer VA: 0x180131450 (name-lea 0x18013141c)
• Method+path (inferred): GET ut/game/fifa17/season/user — load the user's current season state.
• Fields (verified from switch at 0x18013153c):

  atom	key	type	offset	notes
  674	seasonId	int	0x5c
  220	divisionId	int	0x58	(as int here, not str)
  656	round	int	0x60	current round
  881	userPoints	int	0x64	points/progress
  202	dataVersion	str	0x68 (enum byte)
  201	data	str	interned via 0x1801c7d40	large opaque season-state blob string
  —	root/friendlySeasonHistory	nested	via 0x180136880	container — FREEZE-RISK

• Unknown atoms → SKIP 0x180135ff0 (safe).
• MINIMAL JSON:

{"seasonId":1,"divisionId":10,"round":1,"userPoints":0,"dataVersion":"1","data":""}

• GAP.

FutUpdateSeasonServerResponse ★CONFIDENCE: HIGH (ack-only)

• Deserializer: none — factory 0x180168b10 → base ctor 0x18011f850 only (name 0x18022a748).
• Method+path (inferred): PUT/POST ut/game/fifa17/season/user (submit season match result).
• MINIMAL JSON: {}. GAP.

FutSeasonQuitServerResponse ★CONFIDENCE: MEDIUM

• Deserializer VA: 0x180131a30 (name-lea 0x18013197d)
• Method+path (inferred): DELETE ut/delete/game/fifa17/season/user (quit current season).
• Fields: atom 490 offlineDivision = nested (0x18011a830) — division-descriptor object.
• MINIMAL JSON: {} (offlineDivision optional/SKIP-safe; if included must be an object). GAP.

SECONDARY (best-effort catalog)

FutUpdateFriendlySeasonServerResponse ★CONFIDENCE: HIGH (ack-only)

• Factory → base ctor 0x18011f850 only (name 0x18022a840). Method (inferred): PUT ut/game/fifa17/season/friendly. Parses no fields. MINIMAL JSON: {}. GAP.

FutGetFriendlyHistoryDataServerResponse ★CONFIDENCE: MEDIUM

• Deserializer VA: 0x18014d570 (name-lea 0x18014d36d). Path: GET ut/game/fifa17/season/friendly history.
• Fields: atom 675 seasonGamesDraw int @0x24; atom 151 coinsEarned int; (siblings seasonGamesWon/Lost in same offset cluster likely present via SKIP). MINIMAL JSON: {"seasonGamesDraw":0,"coinsEarned":0}. GAP.

FutTournamentListServerResponse ★CONFIDENCE: MEDIUM

• Deserializer VA: 0x180169ef0 (name-lea 0x180169d7d). Path (inferred): GET ut/game/fifa17/tournament.
• Clean scalar fields: atom 348 id int, 212 difficulty int, 149 coins int, 652 rewardMultiplier int, 19 aigroup int, 37 assetName str, 243 eligibilityOperation str. Many nested (rounds, prizeSet, staff, stadiumid, kit atoms 13/16 — treat as FREEZE-RISK objects, SKIP-safe if omitted).
• MINIMAL JSON (array root):

[{"id":1,"difficulty":1,"coins":500,"rewardMultiplier":1,"assetName":"","eligibilityOperation":""}]

• GAP.

FutTournamentLoadDataServerResponse ★CONFIDENCE: MEDIUM

• Deserializer VA: 0x180147cb0 (name-lea 0x180147c7c). Path (inferred): GET ut/game/fifa17/tournament/user.
• Fields: atom 202 dataVersion str, atom 656 round int, atom 810 tournamentData (str/opaque blob, same interned-getter 0x1801c7d40 as season data), atom 92 bonus nested. Mirrors SeasonLoadData shape.
• MINIMAL JSON: {"round":1,"dataVersion":"1","tournamentData":""}. GAP.

FutTournamentQuitServerResponse / FutGetTournamentTeamsServerResponse ★CONFIDENCE: LOW

• Both resolve to deserializer 0x18016bcf0 (names 0x18022af10 / 0x18022b068) — near-empty switch; only nested/opaque atoms seen (teamId, activeBadge). Likely thin/ack-ish. Paths (inferred): Quit = DELETE ut/delete/game/fifa17/tournament/user; Teams = GET ut/game/fifa17/tournament/user. MINIMAL JSON: {} (or [] for Teams if array-rooted). GAP.

FutUpdateTournamentServerResponse ★CONFIDENCE: LOW

• Deserializer VA: 0x1801758c0 (name-lea 0x18017580d). Only enum/opaque atoms (LOCKED_PERMANENT/LOCKED_RETRY/LOCKED_TROPHIES/SUCCESS) — a status-enum response. Path (inferred): PUT/POST ut/game/fifa17/tournament/user. MINIMAL JSON: {}. GAP.

FutGetActiveTournamentsServerResponse ★CONFIDENCE: LOW

Club / Cards / Consumables

Clean-room RE of the FIFA17 CardsDLL (base 0x180000000). Method: each FutXServerResponse class registers a vtable; vtable slot +0x08 is the JSON deserializer. Located via struct-name string → VA = 0x1801e5000 + (fileoff - 0x1e4400) → factory lea r8 xref → vtable install → slot +0x08. Every deserializer shares the same skeleton:

scratch init (0x1801c63e0/0x180008130/0x1801c8270) → NextToken×2 →
get target model (0x18011a830) → key-loop { KEYRD 0x180141ee0 → atom → dispatch } →
unknown atom → SKIP 0x180135ff0 (container-aware, extra keys are SAFE)

KEYRD 0x180141ee0 = read next key, FNV-hash (0x180180d00) → atom int, advance to value. Leaf getters: int 0x1801c79d0, bool 0x1801c7620, string 0x1801c7aa0. Shared ITEM/card element deserializer = 0x18013fe00 (see CARD_SYSTEM.md; produces the 0x100-byte resolved-card record). TYPE FIDELITY IS MANDATORY: an array/object key fed to a scalar getter desyncs the SAX reader → infinite tokenizer spin (freeze at 0x1801c7f1a). Arrays are flagged [FREEZE-RISK] below — they must be emitted as JSON arrays, never scalars.

Key structural finding (contradicts the initial brief)

FutGetClubInfoServerResponse does NOT return itemData/card items. Its only recognized top-level key is user (atom 0x36c), an array of club-user summary records (element parser 0x18012c990, which never calls the card element 0x18013fe00). The card list that actually renders in the club UI is FutViewCardsServerResponse (itemData, via 0x18013fe00) served on ut/%s/item. So "club-wide item search → cards" is ViewCards on /item, while GetClubInfo/GetClubUsers carry club-user stat records. data/ mental model of GetClubInfo = {itemData,count,actives} is wrong for this binary. Actives (homekit/awaykit/badge/etc.) appear as fields inside each user record, not as top-level keys.

---

Per-struct table

Legend: method/path from the ut/%s/... templates in the binary (%s="game/fifa17"). GAP = not (correctly) served by utas_server.py. All unknown keys are SKIP-safe, so {} never freezes any of these — GAPs are "feature missing", not "crash".

Notes:

• 0x1801642c0 is a shared no-op deserializer (function body = ret). Three responses (ChangeClubName, ActivateCard, SignLoanPlayer) use it → their HTTP body is fully ignored; only a 200 + valid JSON ({}) is required. This is why "change name / activate / sign loan" succeed with a bare stub.
• user-record element (0x18012c990, GetClubInfo) is a jump-table parser; caught fields include established(0x110,str), homekit(0x159), awaykit(0x3f), cleansheets(0x84,int), attributeList(0x31), passing(0x214), awardType(0x44), categoryId(0x73), controls(0xb9), changed(0x7e), currentChampionEvent(0xc2). Full field map is PARTIAL (jump table at [0x1412c4] not fully decoded); all fields optional/SKIP-safe.
• card-item element = 0x18013fe00, already reversed in CARD_SYSTEM.md (rating/position/nation/teamid/attributeList/name/resourceId…). Not re-derived here.
• Atom→key mapping from atoms.tsv (FNV-indexed sequential IDs 0x0–0x38a).

utas_server.py integration status

• /item (defs_route) already serves {"itemData":[…]} → satisfies ViewCards, ApplyCard, ApplyCardByRes, MoveCard, ConsumablesSearch, StickerBook, loan itemData shape (though action semantics — updated item / chemistry / credits — are not modelled).
• /club serves {"itemData":…} but GetClubInfo wants user → the itemData is SKIP'd; club card render still works because it goes through /item ViewCards, not /club. To populate the club-user summary, serve {"user":[…]} on /club.
• /clubUser → {} (GAP: should be {"user":[…]}; {} is non-freezing).
• No routes for discard-credits, move-chemistry, staff-bonus, loan loans[], stickerbook → all fall to catch-all {} (safe, feature-inert).

## Store / Packs / Purchases

Reversed from CardsDLL (base `0x180000000`) via the RECIPE deserializer method. All
struct-name VAs computed as `0x1801e5000 + (fileoff - 0x1e4400)`; deserializers located
from the `.text` `lea r8,[name]` xref; atoms translated through `atoms.tsv`.

Parser primitives: INT `0x1801c79d0` · BOOL `0x1801c7620` · STR `0x1801c7aa0` ·
value-SKIP (unknown atom, safe) `0x180135ff0` · next-token `0x1801c7f10` ·
begin-object `0x1801c8270` · key→atom FNV `0x180180d00` · shared ITEM element deser
`0x18013fe00`. **Type fidelity is mandatory** — feeding a scalar getter an object/array
desyncs the SAX reader → tokenizer freeze at `0x1801c7f1a`.

- **Status: already handled (renders in-game), but with CORRECTIONS**
  - `store_catalog()` currently emits `id, packType, quantity, purchaseLimit, purchaseCount, isPremium, saleType` — **none of these atoms exist in the pack deser** (`id`=0x15c, `quantity`=0x26b, `saleType`=0x298, `packType`=0x20f, `isPremium`=0x176 are all routed to SKIP `0x180135ff0`). They are harmless no-ops but do nothing.
  - The **real identity field is `assetId` (0x23)**, which the current handler does NOT send. Recommend adding `assetId` per pack (packs currently work off `currencies`+`extPrice`+`packContentInfo` presence + the transaction-body `packId`, but `assetId` is the field the client actually deserializes).
  - `extPrice.finalPrice/originalPrice` inner keys are NOT `mtx` (no such atom) — real inner atoms are `amount`/`currency`; current `{"mtx":N}` is skipped, so extPrice objects are effectively empty-but-present (enough to pass validation; FIFA-Points price shown comes from elsewhere).
- **Minimal known-good** (corrected):
```json
{"purchase":[{"assetId":101,"description":"Gold Pack","sortPriority":1,

• This is the ut/v2/%s/store response. It is NOT a per-pack quantity list — it is a single eligibility/result gate. The deser reads exactly ONE key:

  • result (atom 0x288) → STRING; the string VALUE is FNV-hashed (0x180180d00) and mapped to an enum stored at [rdi+0x28]:

  string value	atom hit	enum
  SUCCESS	0x2fb	0
  TOO_MANY_TOURNAMENTS	0x324	1
  LOCKED_PERMANENT	0x1a1	2
  LOCKED_RETRY	0x1a2	3
  LOCKED_TROPHIES	0x1a3	4

  All other keys are skipped. Constructor default of [rdi+0x28] is 0 (SUCCESS), so an empty {} also parses as SUCCESS, but send result explicitly.

• Status: GAP — no route builds this. Add a handler for ut/v2/%s/store.

• Carries the credits/currencies balance object. The verified coin-binding path is the shared currencies parser (deser 0x180122c50, atom currencies 0xc5 → [].funds), already served by credits_route() as {"credits":N,"currencies":[{name,funds,finalFunds}]}. Exact per-offset field map of 0x180139610 not fully traced (it is a large shared parser); no correction needed since the coin counter already binds correctly.

Definitive store-availability config flag list (for Blaze client-config)

The store "not available" screen is gated by (a) a resolution check — GetSystemMetrics must be > 1024×768 — and (b) the following Blaze client-config flags. FUT_STORE_DISABLED is a UI message string, not a gate. Confirmed present in cardsdll.strings:

Blaze client-config booleans (must be "1"/true):

• IS_STORE_ENABLED
• IS_COIN_PURCHASABLE
• IS_FIFAPOINT_AVAILABLE
• IS_FIFAPOINT_PURCHASABLE ← additional (found adjacent)
• IS_EASTORE_SERVICE_READY ← additional (found adjacent)
• COINS_PURCHASE_ENABLED
• POINTS_PURCHASE_ENABLED
• MONEY_PURCHASE_ENABLED ← additional (found adjacent)

FUT data/config flags (lowercase, JP-region variants exist):

• cardPackStoreEnabled / cardPackStoreEnabled_JP
• coinEnabled / coinEnabled_JP

Set all Blaze booleans to enabled and ensure the client renders above 1024×768.

Section: User / Hub / Settings / Objectives / Leaderboards / Champions

Clean-room RE of the FIFA 17 FUT boot/hub API from cardsdll.dll disassembly (base 0x180000000). Method: RECIPE.md — struct-name string → lea r8 xref → deserializer field-loop → FNV atom immediates (cumulative sub/cmp jump-ladders) → atoms.tsv. %s = "game/fifa17".

Shared token-type noise (excluded from field lists below): after every NextToken (0x1801c7f10) the parser does cmp eax,0xa / cmp eax,0x6 / cmp eax,0xd — these are JSON token-TYPE checks, NOT field atoms.

Leaf getters: int/num 0x1801c79d0, bool 0x1801c7620, string 0x1801c7aa0. Value-SKIP (unknown atom, safe extra keys): 0x180135ff0. Card/item sub-deser: 0x18013fe00. Feeding a scalar getter an object/array desyncs the SAX reader → infinite spin at 0x1801c7f1a (the hub freeze).

  • settings (0x2bf) → settings deser 0x18013c6d0
  • userData (0x36d) → 0x180142470
  • clubUser (0x91), errors (0x10c), loanPlayerClientData (0x199), loanPlayers (0x19a), pileSizeClientData (0x227)
  • everything else → SKIP (0x180135ff0)
• Freeze history: the documented "any content desyncs" was recorded before the squad schema was reversed; the prime suspect is the malformed squad member fed to 0x18013d1f0. Every user_info() field type-checks against 0x18013ec10.
• Handled: utas_server.massinfo() → {userInfo, squad, settings, userData}; FUT_MASSINFO=full|squad|userinfo|settings|empty bisects it one member per relaunch.

FutGetSettingsServerResponse — CONFIDENCE: HIGH ✅ HANDLED (schema) / the 42 flags are RECOVERED, UNTESTED

• Deser: 0x18013c6d0 (1982 bytes, 12061-char decompile, read end to end)
• HTTP: GET ut/%s/settings, and the settings (0x2bf) member of userMassInfo (both callers of the deser: 0x18014e590 and 0x180174630)
• Fields: single wrapper key configs (0xa2) → array of config entries { type (0x354), value (0x377) }. The key ladder really does hold nothing else.

The mechanism the key ladder hides. A flag is not a JSON key. When an element closes, the client feeds the STRING VALUE of type back through the atom hasher (FUN_180180d00) and switches on the result, 42 arms wide:

{"configs": [{"type": "friendlySeasonsEnabled", "value": 1}]}

So the flag vocabulary is the same atom table everything else uses, and the client hashes our string itself — a flag cannot be misnamed silently, it simply falls through to the default arm and is ignored.

• value is type-forgiving. Its getter 0x1801c79d0 accepts int (token 2), float (3), bool (4) and string (5, via sscanf "%I64d"), coercing all four to int64. 1, "1" and true are equivalent. This is one of the few scalar getters in the API with NO desync risk on scalars. An object or array is still a freeze.
• The applier demands exactly 1. FUN_18011dc50 is the only writer of the gate bytes and every line is gate_byte = (field == 1). Not truthiness. 2, -1 and "yes" all read as OFF.

Flags that publish a UI gate key. FUN_18006cc60 publishes IS_* state keys by reading single bytes inside FutDataManagerImpl (service id 0xed84b11, ctor 0x18010cdc0). Those bytes are written ONLY by the applier, and the ctor never touches them (whole 16620-char ctor scanned):

flag type	field	gate byte	UI key
tradingEnabled	[10]	0x1fd2e	IS_TRADING_ENABLED
storeEnabled / _JP	[0xb] / [0xc]	0x1fd2f / 0x1fd30	IS_STORE_ENABLED (accessor 0x18011c600 picks _JP when region == 4)
friendlySeasonsEnabled	[0x16]	0x1fd3a	IS_FRIENDLY_SEASON_ENABLED
tournamentQuitEnabled	[0x20]	0x1fd3b	IS_TOURNAMENT_QUIT_ENABLED
processingStateEnabled	[0x21]	0x1fd3c	IS_PROCESSING_STATE_ENABLED
enableDraftMode	[0x17]	0x1fd3d	IS_DRAFT_MODE_ENABLED
enableOfflineDraftMode = enableSinglePlayerDraftMode	[0x18]	0x1fd3e	(shared arm, one field)
storyModeRewardEnabled	[0x1f]	0x1fd3f	IS_STORY_MODE_REWARD_ENABLED
returningUserRewardsScreenEnabled	[0x19]	0x1fd40	IS_RETURNING_USER_REWARDS_SCREEN_ENABLED

Why this is the standing suspect for Seasons and Draft. Both refuse while making zero requests to any of the four servers, which no response shape can explain. A UI key evaluated from a byte that nothing ever wrote does explain it. The store is the control: IS_STORE_ENABLED reads the same kind of byte and its screen works, because storeEnabled and friends are already shipped through the Blaze client-config store (FUT_RS4_CONFIG in blaze_responder_v3b.py) — and that list contains no seasons, draft or tournament flag. Same mechanism, one population, one blank.

This is a hypothesis with a mechanism, not a confirmed cause. It predicts that sending the flags opens the screens; if they still refuse, the gate is upstream of the UI key and the whole settings line is dead.

Two arms that are not simple assignments:

• enableObjectives (0xfd) and enableObjectivesAsManagerTasks (0xfe) share an arm that can only ever CLEAR [0x1c]: if (value == 0) field = 0. Sending 1 is a no-op. Objectives cannot be turned ON here, only off.
• clientKeepAliveResetTimeoutSec (0x86, vtable +0x68) and getOperationTimeoutSec (0x13d, +0x58) do not store a field; they call a timer object with value * 1000. Sending a small number shortens client timeouts. Leave them alone.

maximumTradePileSize (0x1c0) is the positive control. It lands in [0] and is passed to FUN_18011f380, and transfer-list capacity is visible in game. It distinguishes "the flag did not help" from "the configs array never reached the consumer at all", which no boolean flag can do on its own.

Not in the switch: enableSquadBuildingSetsFeature (0x100) is a real atom but has NO arm here, so SBC is gated somewhere else. Scanned the full decompile; this absence is asserted over the whole function, not a slice.

• Handled: utas_server.SETTINGS, FUT_SETTINGS (default gates). off restores the historical {"configs": []}.

FutGetHubDataServerResponse — CONFIDENCE: LOW (full schema) / HIGH (served {} works) — GAP

• Wrapper: 0x1801736ad → inner 0x180173a50 / 0x180173b10 / 0x180173c00.
• HTTP: GET ut/%s/hub
• Note: uses C++ reflection / vtable dispatch (call [rax+0x10], call [rdx+0x1f8]), NOT an inline atom ladder — no static field ladder to read. It aggregates sub-objects (userInfo, settings, messages, etc.), each with its own deser. Empty {} is tolerated (fields default).
• Handled: utas_server serves {} (validated hub-reaching). Deep populate = GAP.

FutUserDataServerResponse — CONFIDENCE: MEDIUM

• Deser: 0x18016dd50 (lea r8 @ 0x18016d98d)
• Fields: actives (0xb, array), key (0x177), value (0x377) — key/value user-data entries. Part of create/user path. Served inside userData.

Implementation status & leads (updated 2026-08-02, autonomous session)

• Store — FIXED (v2/store SUCCESS gate + 14 Blaze flags + catalog assetId/extPrice). Live-verified server-side.
• Transfer market — IMPLEMENTED read path: auctionhouse search serves 18 real-player listings (auction record 0x18013e410, itemData via proven 0x18013fe00); tradePile/watchList empty; validated freeze-safe offline by tools/test_fut_contract.py (311 checks). Toggle FUT_MARKET=empty. NEXT: buy/bid flow (stateful — deduct coins, grant card, echo updated auction) — needs live test.
• SBC — LEADS (not yet enabled; need live test): feature gate flag enableSquadBuildingSetsFeature; FUT/SBC_USE_STUBS (BRICK) may enable client-side stub SBCs with NO server content (safest path — try first); set-list deser 0x180154990 (vtable 0x180226fc0 slot+0x08) is a string-scanning/callback parser, not a clean atom ladder (envelope key not cleanly resolvable statically); requirements are SBC_ELG_KEY_* eligibility triples. SBC_TIMER_EXPIRED present. Recommended: set enableSquadBuildingSetsFeature + FUT/SBC_USE_STUBS in Blaze config and observe whether the SBC menu populates from client stubs.
• Draft — deferred (stateful pick-progression state machine; broken state soft-locks — needs live test).
• Match rewards — reversed (FutDestroyMatch 0x180121b60 coin fields) but stateful — needs live test.
