Operator report: selecting a kit in the pre-match selector gives "This kit is
currently locked. To unlock and use it, please go to the football club
catalogue."
Root cause, from static RE of the UNPACKED CardsDLL. CardsDLL registers a kit
provider into the FIFA engine (singleton FUN_1800338f0, vtable 0x1801f1d68):
slot +0x08 FUN_180033770 enumerate kits for a team
slot +0x10 sub_180033430 describe one kit <- the lock gate
The describe function decodes a packed kit id into (teamid, year, slot) and
compares it against the club's ACTIVE HOME and ACTIVE AWAY triples. On a match
it writes NAME/TYPE (and, for historical kits, LOCKED). On no match it writes
NOTHING AT ALL and the descriptor falls through to the engine's own default,
which is where the locked-catalogue message comes from.
The active triple is 100% server-driven. FUN_1801c26d0 -> FUN_1800d73d0 scans
club items for cardtype 7 + cardsubtypeid 9 + itemState 101/102, then reads:
teamid <- item+0x94 (atom 0x306) we were sending this
year <- item+0xba (atom 0x389) WE WERE NOT SENDING THIS
slot <- item+0xb8 (category) WE WERE NOT SENDING THIS
category 2 -> slot 0 home, 3 -> slot 1 away, 5 -> slot 3 third
So we shipped kits carrying only teamid, and the triple could never match.
fifa17-recon/data/club_items.json already has category and year per kit
resourceId (1482 kits; category {2:740, 3:654, 5:88}; 85 historical years), so
this is carried through the catalog rather than invented: Fifa17CardIdentity
gains category/year, Fifa17KitIdentity carries them, and shape_club_item emits
them for KIT_SUBTYPE only. Badges and stadiums deliberately do not gain the
fields - the slot mapping is kit-specific, and sending a family a field its
resolver does not read is how this project previously froze the client.
Also corrects the Vault note: item+0xba is `year`, not `kittype`. The side comes
from itemState 101/102 and the slot from category.
Two things this does NOT fix, both client-owned and recorded rather than
guessed:
- the runtime teamkits clone into FUT club 130000 (the kit ART) is gated on
item+0x60 == 4, and +0x60 has no wire atom at all: the deserialiser
unconditionally zeroes it, the only CMP against 4 in the whole DLL is
0x1801c34f1, and a live probe measured it as 1 for players / 0 for staff,
never 4. The existing lib.rs claim that a server can never produce 4 is
CONFIRMED, though its stated reason was a live observation rather than the
real one (no wire atom exists).
- whether a year==0 kit needs an explicit LOCKED write is UNKNOWN: CardsDLL
only writes LOCKED for year != 0, and the engine's default for an untouched
descriptor is in Denuvo-packed FIFA17.exe.
openfut-adapter-fifa17
The FIFA 17 game adapter. Everything true of FIFA 17 specifically lives here, so that neither OpenFUT Core nor the generic protocol crates have to know about it.

Status

Nothing here is wired into the running backend. The crate answers frames; it opens no socket, terminates no TLS and owns no runtime. The Python backend remains the live service and the behavioural oracle.
What the adapter owns, and what it must not
Owns: component/command/notification IDs, response body shapes, dispatch
ordering, session identity, the fetchClientConfig tables.
Must not own: FUT domain state. Blaze is an auth/session/config protocol — no
coins, packs, clubs or squads appear on this wire — so Session holds a session
key, a locale, a service name, an auth code and a flag, and that is all. When
UTAS is migrated that boundary will need active defending; here it comes free.
Parity
./check-parity.sh # oracle freshness + byte-for-byte replay
./check-parity.sh --regen # after an intentional oracle change
fixtures/blaze_transactions.jsonl holds 49 request→response(s) transactions
produced by calling the real blaze_responder_v3b.dispatch(). They replay in
order against a shared session per connection, so ordering-dependent behaviour
is exercised rather than assumed: preAuth captures the locale that later ALOC
fields echo, and login sets the auth code getAuthToken returns afterwards.
Comparison is byte-for-byte including frame count and order — a missing post-login notification or a reply where the oracle stays silent fails here.
The suite was mutation-tested: swapping two post-login notifications,
flipping one enum deep inside AccountInfo, and hardcoding an address in
utas_base()/nucleus_base() were each verified to turn it red. The third
initially did not, because the config templating had made those helpers dead
code; the table now templates on URL-level tokens so they are the single place a
URL shape is defined.
Three behaviours that are easy to get wrong
- Login answers with four frames, in order: reply, then
UserAuthenticated,UserSessionExtendedDataUpdate,UserAdded. - An unimplemented RPC still gets an empty reply. Silence makes the client wait for a timeout; an empty reply lets every field fall back to a client-side default and the boot continues.
- Non-request message types get nothing at all.
No error replies are emitted. msgType 3 exists, but the error-code placement
is UNRESOLVED — three clean-room sources disagree between header[14:16], a
metadata ERRC, and a payload CNTX/ERRC — so emitting one would be a guess
on the wire.
The client config table
fixtures/client_config.json carries 227–243 rows per CFID, generated from the
Python oracle and templated on {utas_base}, {nucleus_base},
{pow_content_url}, {advertise}, {bind}, {pow_host}. It is
reverse-engineered data, not logic, and deriving it mechanically removes a
class of transcription typo no reviewer could catch. The generator does not take
its own templating on trust: it substitutes real addresses back in and diffs
against the oracle for every section before writing the file.
The table must be complete, not representative. The client resolves a per-call
key (FUT_RS4_URL_<CALL>) before a per-module one, and any unresolved call falls
back to a real, dead EA host — that is what produced "there has been an error
connecting to FIFA 17 Ultimate Team" mid-session when only the boot subset was
served.
Known defect reproduced deliberately
nucleusConnect and nucleusConnectTrusted are built from the bind address,
not the advertised one. On the live split deployment that means the backend
tells a client on another machine to reach Nucleus at http://0.0.0.0:42131,
which it cannot. Verified against the running container, not inferred.
This is reproduced exactly, because it is what the only proven-working configuration does and changing it would break parity. It also implies the Nucleus stub is not actually reached in the current remote flow. Fixing it is a separate change that needs live validation — see the vault.
Configuration
Nothing is hardcoded. AdapterConfig carries Identity (persona, ids, email,
namespace, entitlement group, …) and Endpoints (advertise, bind, POW hosts,
telemetry/ticker/QoS ports). Default gives the project's synthetic offline
identity on loopback; a remote deployment must override advertise.
Bind and advertise are deliberately distinct: an advertised URL must carry the address the client can reach, which on a two-machine deployment is not the address the server binds.
