Every real squad save was failing with 400 unresolved_wire_ids. Reproduced on staging with the repo's own seeder, which sends the captured retail body: route=squad-replace status=400 outcome=unresolved_wire_ids detail=[[100000427]] FIFA 17 always sends a manager ref, and on a real profile it does not resolve to an owned instance. scripts/sold-staging-seed-squad.py already recorded why: production's own squad points at instance 100000427, which is absent from production's /club/staff (1975 items spanning 100000001..100004826), and the client accepts that squad back unchanged -- so the client never validates the manager against the club, and the pre-0023 server accepted it. Making the manager ownership-backed (d37a9d5/25f4ad1) turned that ref into a hard refusal, which took out the primary FUT write path: no squad save means no squad, which means the client will not enter the FUT hub at all. A manager ref is not a squad slot. An unresolvable PLAYER slot must still refuse the save -- committing it would silently drop an owned card from the club. An unresolvable MANAGER ref just means there is no ownership-backed manager, which is exactly the state before migration 0023: the save commits, the assignment is cleared as a full replacement should, and the id is reported on ProposedSquad::unresolved_manager_wire_id so the host can log what it could not map instead of letting it vanish. A ref that DOES resolve is still assigned and still authorized against the club. Verified end to end on staging: the seeder now answers {"id": 0} with 11 occupied slots, the host logs `manager_ref_unresolved=100000427 (saved with no manager assignment)`, and the projected squad carries `manager: []`.
OpenFUT
⚠️ Status — see
docs/PROJECT_STATE.md(canonical). The working, actively-developed target is FIFA 17, not FIFA 23. Everything below this banner describes the superseded FIFA 23bridgelineage and is kept for historical context.Run the server (canonical):
cd fifa17-recon/docker/fifa17-python && docker compose up -d— seefifa17-recon/FUT-RUNBOOK.md.openfut-coreis the shared offline backend (still used by the FIFA 17 path);openfut-bridgeis the retired FIFA 23 integration.
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.

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.
