Adds openfut-adapter-fifa17 fut::store_catalog — a pure, faithful Rust port of the
Python oracle's PACK_CATALOG + _pack_body + store_catalog assembly at production
flag defaults (FUT_STORE_DISPLAYGROUP=1, GROUPID=0, PRICE_PROBE=0):
- PackDef + PACK_CATALOG (ids 1/5/6/7/70; economy numbers are OpenFUT PLACEHOLDER,
wire shape is oracle-verified; 65534 deliberately absent).
- pack_body() (_pack_body port), sentinel_body() (id-65534 compatibility shim),
build_purchasegroup(unopened_ids, StoreMode) mirroring store_catalog(3627).
- Differential parity: fixtures generated from the Python oracle
(tests/fixtures/purchasegroup_{zero_sentinel,zero_clean,pack70}.json); Rust output
matches semantically (6 tests). Adapter 140 tests, host 24, fmt/clippy clean,
Python A-R oracle green.
PURE wire shaping — NOT wired into the live host. Serving purchasegroup from Rust
requires an authoritative Rust owner of unopenedPackIds, which is blocked on the
economy-authority prerequisite (R3): coins are one shared balance written by many
Python-oracle routes (BUY spend, quick-sell credit, SBC/match/objective rewards)
persisted to fut_profile.json, so no single coin-touching route can move without a
whole-cluster migration. No dual-write introduced; no production deployment.
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.
