Return to Club is durable across a full FUT exit/re-entry — the last claim the forSale promotion could only make server-side. Same disposable card as Gap 1 (75 ST, res 212188, wire 100000178, tradeId 1000000178), after the 1h auction expired NATURALLY. No timestamp was mutated in either gap; a read-only sampler watched the whole hour (55 samples), because `expires` is derived from created_at + duration and watching is the only honest way to see expiry: active expires 3175 -> counting down -> expired expires 0, itemState forSale (absent) total 0 <- Return to Club itemState stayed forSale across active -> expired, the one state change Fix B had never been watched through live. The host log then shows the coupled transition and TWO session boundaries: route=move-items wire=100000178 pile=club auction_cancelled=1 route=auth-delete route=auth ... sid_opened=true (fresh session, x2) route=hub clubPlayers=1966 auctionCount=0 route=club total=1986 emitted=1966 auction_cancelled=1 is cancel_active_for_core_item firing, so pile membership and auction lifecycle cannot disagree. Two independent fresh sessions each rebuilt the state from durable storage and the operator confirmed the card was still in My Club; one boundary was the requirement. 18/18 server checks pass IDENTICALLY before and after re-entry: /tradePile total 0, counts all zero, tradeId -> closed with expires 0 (still resolves, correctly terminal), /club 1966 with itemState free, 0 duplicate ids, market store cancelled with 0 active and 0 reserved, coins 29,843,976 unchanged throughout. No code change was required for EITHER gap. Both tests existed to find out whether the promoted implementation was already correct on paths it had not been exercised on, and it was. Also freezes the full CLUB -> list -> active -> expired -> Return to Club -> CLUB lifecycle as the reference baseline, with the eight invariants it pins, so a future change that alters any line is a regression until proven otherwise. Explicitly NOT established: the SOLD path, /tradePile/counts semantics, the AVM1 gate.
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.

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.
