openfut-import-fifa17/tests/durable_import.rs drives the REAL import pipeline
(analyze -> Report dry-run; emit_content; plan_apply -> GenericImportRequest +
deterministic identity mappings + watermark; the staging/preflight/seed/
post-validate gates over a real JsonIdentityStore; openfut_core::services::
import::apply_profile_import in one Core SQLite tx) against a disposable
temp-file Core DB, from a small sanitized in-test fixture (750000 coins, 3
resolvable base players, unopenedPackIds [70,70,101], one squad).
Five ordered steps on one durable target, all green:
A dry-run: report exposes persona/coins/inventory/unopened/fingerprint; ZERO
DB mutation (all Core tables COUNT=0, identity store empty).
B apply: coins=750000 exact, owned=3, packs=3 (opened=0), squad_players=2,
deterministic owned ids, import_fingerprint recorded, identities reverse-
resolve both ways, watermark=100000600.
C restart: close+reopen the SAME sqlite file -> identical state.
D re-apply same source -> AlreadyImported (fingerprint), no doubling.
E conflict (coins 750000->750001 flips the fingerprint for the same game)
-> apply fails closed ('different source'); DB unchanged.
Fingerprint = FNV-1a-64 hex of the source snapshot, carried into
ProfileImportRequest.source_fingerprint = Core profiles.import_fingerprint, the
per-game rerun-identity key. dev-deps added to openfut-import-fifa17
(openfut-core path, tokio, sqlx). No production/live data.
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.

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.
