The one claim the Fix B promotion left open: no active listing existed during
that session, so only the expired path had been exercised.
Closed with a disposable card (75 ST, res 212188, wire id 100000178 — one of
three identical copies, not in the squad) listed through the real FIFA 17 client
at 150/200 for 1h, so expiry arrives naturally. No timestamp touched.
Wire: itemState=forSale, tradeState=active, 12 atoms, prices intact, expires
3562 -> 3556 over a 6s sample (live clock), /trade/status coherent, counts
{count:1, selling:1}, coins unchanged, zero inactive rows (Fix A intact).
The decisive evidence is client-side, not ours: a read-only /proc/<pid>/mem
decode of the live trade-pile auction record returned
itemState=5(forSale)
on the very field that read -1(<unrecognised>) under listFS. Direct A/B on the
only changed field, taken from the client's own memory.
Operator confirmed the row renders under LISTED ITEMS with correct prices, a
counting-down timer, normal art, and correctly non-actionable while active.
No code change required — the promoted implementation was already correct on the
active path. Claim boundary unchanged: this proves the client DECODES the token
and says nothing about the Flash action-gate term.
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.

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.
