Second correction in an hour, and this one comes from reading the provider instead of
reasoning about it. The per-context getter is (+0x7f8)(store, contextValue, typeId),
and contextValue comes from THE UI ROW, not from the URL:
case 3: uVar7 = (**(param_2 + 0x18))(param_2, row, "LEAGUE_ID")
bronze = (+0x7f8)(store, uVar7, 2)
silver = (+0x7f8)(store, uVar7, 3)
gold = (+0x7f8)(store, uVar7, 4)
publish "PLAYERS_EMPLOYED", gold + silver + bronze
rare/kits/badges = (+0x7f8)(store, uVar7, 5 / 0x28 / 0x2d)
case 4: keyed by "TEAM_ID"; reads 1 (players), 0x28 (kits), 0x2e (badgeDBid)
Three things my previous commit got wrong:
1. It keyed every row to the id in the URL. The reader iterates the SCREEN'S ROWS and
looks up each row's own id, so one response must carry a bucket per row. Keying to
the URL id fills exactly one bucket the screen never asks for, which is why the
ENGLAND tab still showed zeros after the "fix".
2. PLAYERS_EMPLOYED is COMPUTED as gold + silver + bronze in the per-context cases and
is never read from the store, so sending `players` (type id 1) does nothing there.
The tier counts are mandatory.
3. The screens NEST: country/<id> lists the LEAGUES in that nation (case 3, LEAGUE_ID)
and league/<id> lists the TEAMS (case 4, TEAM_ID). That matches the live navigation
exactly: selecting ENGLAND produced Premier League / Championship / League One /
League Two.
Because every response wipes the whole map, each response only needs its own screen's
buckets, which also avoids a real collision: the storage key is contextValue alone, so
nation 14 and league 14 would otherwise share a bucket.
Live output now:
country/14 -> 41 rows, 5 league buckets
league 13 gold=17 -> PLAYERS_EMPLOYED=17 (Premier League)
league 19 gold=26, league 53 gold=55, ...
league/13 -> 6 team buckets {5:20, 21:15, 22:11, 240:21, 241:30, 243:17}
Recorded as a method note: two rounds of reasoning about this endpoint produced two
wrong bodies, and reading twenty lines of the provider produced the right one. The
question "what does the reader look up" is answerable and was not asked.
392 + 61 checks green, zero tracebacks. Still behind FUT_CLUBSTATS, default off.

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 |

Game-independent offline FUT backend |

SQLite database
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.
