FUT modes (Seasons/Tournaments/FUT Champions) and the club-identity service are
disabled in this emulator, so these GET reads return {} verbatim from the Python
oracle. Serve them directly from Rust via a new Route::FeatureOffEmpty +
non_economy::feature_off_body() -> {} (byte-identical to the flag-off oracle),
reducing the proxied Python surface.
- The mutating club rename (user/club) stays on Python (needs a Core write).
- Enabling a mode later requires a real Rust handler here, never a Python
fallback (no split authority).
- classify tests: 5 routes owned + user/club/wrong-method lookalikes stay
Passthrough; updated the stale clubUser assertion.
- Deployed to prod-host 2026-08-17; verified owner=RUST 200 {} for all five.

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.

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.
