shape_item hardcoded rareflag=1, so all 1949 cards shaped as basic rare gold regardless of type; informs/specials lost their card art. The dev fixture is base-only, so this was invisible until the real profile (10 distinct rareflag values) exposed it on .105. rareflag is definition-level FIFA identity metadata OBSERVED from the profile (the raw wire integer, never a guessed marketing label), so it lives in the FIFA catalog like asset_id/version, not in generic Core: - ObservedDefinition.rareflag + emitted into the production catalog entry. - Fifa17CardCatalog RawCard/Fifa17CardIdentity gain rareflag (default 1 when a base-only catalog omits it, preserving prior wire behaviour). - Fifa17Identity.rareflag; host resolver populates it from the catalog. - shape_item emits id.rareflag instead of a hardcoded 1. Verified on the real staged /club: wire rareflag distribution == source exactly (0 per-item mismatches across 1949; e.g. rareflag 3 x591, 24 x302, 21 x256). adapter 111 + host 24 + importer 25 tests green; clippy -D clean. rareflag lives in the host catalog, not Core, so no re-import was needed.
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.

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.
