funman300 b6398c44e6 docs: record the LIVE-CONFIRMED inactive UI contract and the expired->Club transition
Operator confirmed in the real client that a tradeState "inactive" row lands under the
right-hand TRANSFER LIST section and renders Start Price 0 with Buy Now, Current Bid
and Time Remaining all absent, while an active row in the same body continued to
render separately under LISTED ITEMS. That is the Q2 representation confirmed live,
with the token itself dumped from the client's own string table rather than guessed.

Records the observed wire->UI contract as a table plus a fixture
(inactive-row-live-confirmed.json), and names the regression tests that pin it,
including the two guards that the row is never emitted for an item outside the trade
pile and never duplicates a real auction.

Also records the expired->Club coupled transition verified server-side: the listing
went to `cancelled`, the pile went to `club`, /tradePile dropped the item, /club
regained it, and clubPlayers went 1964 -> 1965. That is durable store state rather
than a client-local view, so it survives a session boundary by construction; tagged
pending the operator's final exit/re-enter confirmation.

Adds the counts observation table. `count` currently tracks AUCTION entries and not
total Transfer List membership; semantics deliberately left unchanged until the full
state set has been observed.

No behaviour change in this commit.

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.

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.

Disclaimer

This project is not affiliated with EA Sports. You must own FIFA 23 legitimately to use this software. This project does not bypass any ownership verification and is intended only to restore offline playability of a game whose online services have been retired.
