Round 3, 10 agents. The headline is measured, not inferred: GET club/stats/consumables
is requested 41 times per session by the real client (ProtoHttp), and _club_stat_set()
answers it with the PLAYER stat set. The panel reads 14 consumables* names that we
have never sent, so it is told '205 players' when it asked how many contracts the club
owns, and it has nothing to show.
That also explains why last round's 126-item consumable shelf was never requested. It
serves type=contract|training|healing|development and an UNTYPED /club with no
team=/league=, and all 9 of the client's untyped requests this session carry team=. The
only +126 item(s) line in the whole log came from one of our own probes.
Vocabulary recovered: the 14 consumables* rows plus badgeDBid 0x2e, kitsHome 0x29,
kitsAway 0x2a, leagueLogos 0x2f, trophiesSeasonOnline 0x38.
Other measured surfaces the client asks for and we fob off: GET /settings 11x answered
with an empty config array (a 40-flag feature gate, the biggest untouched lever in the
project), leaderboards/options 5x with {}, user/accountinfo 4x with {}.
club/stats/staff is a DIFFERENT class (FutStaffBonus); the staff counts come from the
Stats2 store, which is why the staff screen worked while we answered {}.
Refuted: ENDPOINT_MAP's claim that objectives have no route. FUN_180151610 builds
<base>/objective/%d/reward and FUN_180147780 builds .../complete.
New modules only. utas_server.py is deliberately untouched: whether to wire the counts
depends on a free observation the human can make on the client that is already running,
and spending a restart before that is what this round exists to avoid.

OpenFUT
Offline Ultimate Team — like SPT, but for FIFA 23.
OpenFUT replaces EA's retired FUT servers with a fully offline, single-player backend. You own FIFA 23 legitimately. You just want to keep playing after EA shut down the servers.
Repositories
| Repo | Purpose |
|---|---|
openfut-core |
Game-independent offline FUT backend |
openfut-bridge |
FIFA 23 integration layer + reverse-engineering proxy |

Core is game-independent. It speaks a clean REST API and knows nothing about FIFA 23 internals.
Bridge is FIFA-specific. It speaks FIFA 23's wire protocol and translates it into Core API calls. Bridge is where all reverse engineering work happens.

Running
# Start the offline backend
cd openfut-core
cargo run
# Start the proxy (for traffic capture / FIFA integration)
cd openfut-bridge
cargo run
Core listens on http://127.0.0.1:8080 by default.
Bridge listens on http://127.0.0.1:8443 by default.
Design Principles
- Offline-first. No EA account required. No internet connection needed.
- Single-player only. This is not a multiplayer server emulator.
- Data-driven. All cards, packs, SBCs, and objectives are JSON files. Everything is moddable.
- Clean architecture. Core has zero knowledge of FIFA 23. Bridge has zero game logic.
- No copyrighted assets. No real player images, no EA trademarks in data files.
