funman300 97498c560e docs(re): refute the contract:7 effect source; record the competing development reading
Two corrections found while trying to close the effect boundary statically.

1. `contract: 7` IS OUR OWN PLACEHOLDER. fut_store.py:232's generic _item()
   factory -- which builds every item the oracle serves -- hardcodes
   playStyle 250 / contract 7 / fitness 99 on players and consumables alike. The
   staging GK reads back exactly those three constants. So the production
   catalog's contract:7 for resource 5001004 is an oracle placeholder
   round-tripped through an observed profile, not an EA value. Its status is not
   INFERRED, it is KNOWN-BOGUS as a source. Had the effect been implemented on
   it, it would have been a fabricated game rule wearing observed-data clothing.

2. fcc_contractcards is NOT amount-less. An earlier note here claimed it "has no
   amount column, so this value comes from observed data". It has 13 rows with
   gold/silver/bronze/rating, 6 player + 6 manager paired by rating plus a
   99/99/99 special. The sibling fcc_healingcards shares every column except
   that it carries a single `amount`, which argues the differing columns ARE the
   effect payload (per target tier). Against that: the values are non-monotonic
   across tiers, which suits weights better than amounts; and no column of
   5001004 is 7, so neither reading explains the placeholder.

   The reader that would settle amount-vs-weight is in FIFA17.exe, not CardsDLL
   (the table and column literals are absent from the DLL), so this stays
   EFFECT_UNKNOWN rather than being guessed.

Also records, in content_taxonomy.rs, the competing reading of `development`:
fut_consumables.py's TYPE_CATEGORIES groups it as card-categories {6,7,8,9,10}
(modifiers only), explicitly flagged there as inferred from UI-bucket names and
never observed on the wire. Different enum space from the CONSUMABLE_TYPE switch
that actually emits the segment, and the switch gives formation/position/
playStyle/managerLeagueModifier their own segments rather than folding them into
development -- so the unfiltered reading is better supported, but it is still a
reading and the doc now says so instead of sounding settled.

248 adapter tests, fmt clean. No behaviour change.

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.

  openfut-protocol-blaze   generic Blaze: Fire2 framing, Heat2/TDF codec
           ▲
  openfut-adapter-fifa17   THIS: command tables, response bodies, dispatch order
           ▲
  OpenFUT Core             game-independent FUT domain (not yet wired)

Status

Surface Port State
Blaze / Fire2 RPC 42130 Implemented, byte-for-byte parity-tested
Redirector (HTTPS + XML) 42127 Python only
Nucleus OAuth stub 42131 Python only
LSX / Origin 4216 Python only
Roster XML 8081 Python only
UTAS / RS4 8099 Python only
POW / EASFC 8094 / 8080 Python only

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 227243 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.
