ENDPOINT_MAP said this class reads one key, `configs`, and that was true and useless. What it missed is what happens after each element closes: the client feeds the STRING VALUE of `type` back through the atom hasher and switches on the result, 42 arms wide. A flag is a row, not a key, and the client hashes our string itself. Followed it to the end. FUN_18011dc50 is the only writer of the IS_* UI gate bytes inside FutDataManagerImpl, every line is `byte = (field == 1)`, and the constructor never touches those bytes. So a flag nobody sends is a gate nobody opens. friendlySeasonsEnabled and enableDraftMode have never been sent by anything, which is a mechanism for Seasons refusing while making zero requests to any of the four servers. The store is the control that makes this readable: IS_STORE_ENABLED is the same kind of byte and its screen works, because storeEnabled and friends already ship through the Blaze config store. That list has no seasons or draft flag. Ship the gates behind FUT_SETTINGS (off/keep/gates, default gates), and re-assert the working store flags in the same array on purpose: once a populated array makes the applier run, it writes EVERY gate byte, so omitting them could switch off a screen that works today. maximumTradePileSize=100 rides along as a positive control, because a boolean that changes nothing cannot distinguish "the flag did not help" from "the array never reached the consumer". check_settings_flags.py asserts each shipped name against the atom table AND the recovered switch, since a misnamed flag is silently inert and looks exactly like a failed fix. enableSquadBuildingSetsFeature is the reason both checks are needed: a real atom with no arm here. Live: 439 contract checks pass, market unit suite passes. Not yet tested in game. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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.

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

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.
