funman300 6f16a231fc fix(fifa17): implement rare=SP 'Special' club filter via rareflag
The club search 'Quality = Special' sends rare=SP, which was a deliberate no-op
('semantics UNKNOWN'), so it returned every card — base golds included. The
rareflag work now grounds it: a special is rareflag > 1 (base rare = 1),
evidence-backed by the FIFA17 taxonomy + the observed profile (base Ronaldo/Messi
rareflag 1; their informs 11/24).

rareflag lives in the FIFA catalog, not Core, so Core cannot filter it:
- map_to_core: rare=SP now sets CoreOwnedQuery.special (host-applied), not
  'unsupported'; any OTHER rare value stays unsupported. special is NEVER a Core
  /collection param. is_special_rareflag(rf)=rf>1 lives in the adapter.
- handle_club special path: fetch all items matching the OTHER filters (offset/
  limit stripped), shape (resolves rareflag), then special_filter_page() keeps
  rareflag>1 and paginates the FILTERED set locally (start/count over specials,
  not Core's unfiltered page) — no base leakage, no post-pagination drops.

Verified live on the real staged club: rare=SP -> 1665 items (=1949-284 base),
rareflag distribution all >1, zero base leaked; pagination page0==full[0:50],
page1==full[50:100], no overlap. Tests: adapter map rare=SP->special, unknown
rare stays unsupported, is_special_rareflag predicate; host special_filter_page
filter+paginate. adapter 113 + host 25 + importer 25 green; clippy -D clean.

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.

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.

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.
