openfut-identity: - insert_existing_mapping(game,kind,core_id,external_id): preserve an existing external wire id instead of minting; idempotent for an identical mapping, rejects conflicting forward/reverse with IdError::Conflict, persists atomically. - persisted per-scope allocator watermark (set_watermark/watermark_for) so a future mint continues past the source high-water even across burned-id gaps; next id = max(base_floor, live_max+1, watermark). Backward-compatible on-disk format (legacy bare [Row] still loads). +4 tests (10 total). openfut-import-fifa17 (new): read-only dry-run analysis of a real FIFA17 Python profile for a faithful Core import. Enforces disjoint item-class balance; proposes profile-derived CardDefinitions keyed fifa17_<resourceId> (base vs versioned never collapse) with a resourceId-group consistency gate (hard-fail on disagreement, never pick a winner) and honest buildability (roster name + version formula + metadata, never fabricated); plans owned-instance identity (preserve Python wire ids, preserve nextItemId watermark); checks active-squad coverage. --apply/--emit-content refuse to write in this phase. 11 tests. Real profile (33068179/CAGE) dry-run: 1982 items balance (1962 players + 17 consumables + 3 staff); 1681 supported defs (155 base + 1535 versioned), 9 NoName unsupported, 1 hard conflict (resourceId 169193: one of 4 copies has a divergent nation/team/league); 1949 importable player instances, watermark 100004617 -> first new alloc 100004617; active squad f433 fully supported. fmt + clippy -D warnings 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.

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.
