OpenFUT Agent

Two real host-dispatch test files (no fakes) driving Server::try_handle_economy against a live in-process Core over the real blocking client + durable MarketStore/PileStore + JsonIdentityStore, each racer its own OS thread (off-runtime pattern). economy_concurrency.rs — 8 races x 50 iterations: A two BUYs (coins for one) -> exactly one 200 + one 461, final 0, one debit. B duplicate owned-pack open -> one redemption, +11 once, entitlement once. C duplicate quick-sell -> one sell + one credit + one removal. D two market buyers -> one win, one debit, one mint, sold once. E reward+BUY -> no lost update (Core relative UPDATE under BEGIN IMMEDIATE). F move+quick-sell / G list+quick-sell -> one coherent transition. H 1000 concurrent mints -> unique + reversible wire ids, monotonic watermark. economy_failure.rs — 10 fault-injection sub-cases, all fail-closed: BUY/open-redeem/generator/pile/identity, quick-sell, move, market reserve/purchase/complete. CRITICAL complete-sale-after-commit = SAFE: the listing is left `reserved` (not active), so the active->reserved reserve CAS can never win again -> not buyable, exactly one debit + one mint. No E3. Fault injection uses test-file CoreEconomy/ExternalIdentityStore doubles plus a NARROW, inert-by-default `StoreFault` seam in market_store.rs + pile_store.rs (the concrete stores have no trait boundary; 3 `tripped()` checks + a field, zero behaviour unless a test arms it). `parking_lot` promoted to a normal dep (the seam's Mutex is used at lib scope). Classifier/ROUTE_AUTHORITY/Python untouched. host lib 71/71; both new tests pass.
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
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.
