Harden the empty-My-Packs capability binding so a verified FIFA process can never
enable clean/no-sentinel Store topology for another unverified process that merely
shares its source IP. The prototype keyed the decision by source IP alone; two FIFA
processes (concurrent, or a relaunch) share an IP, so an unpatched process could
inherit a patched one's clean-v1 mode and crash. Source IP is now auxiliary only.
- Authoritative key = the per-login UTAS session id (X-UT-SID). /ut/auth now mints
a fresh unique SID per login (was a shared constant) and opens a session record
keyed by that SID; the client echoes it on every later call incl.
/store/purchasegroup (live-confirmed). The legacy constant is still accepted by
the retired security-question gate only, never to grant clean-v1.
- Session state: _FIFA17_SESSIONS[sid] = {ip, persona, resolver, mode, created,
last_seen}. Store mode freezes at the first /store/purchasegroup of the session
and is immutable thereafter. Fail-closed: unknown SID, or a SID presented from a
different source IP than it was opened on, resolves to the sentinel.
- Launcher capability (out-of-band; cannot know the SID) is matched by (ip, persona)
as a SINGLE-USE, short-TTL pending, bound to exactly one session at whichever comes
first: its login (pending predates auth), the registration (session already live),
or its first store request. Ambiguous same-(ip,persona) concurrent registration is
ignored-late -> both sentinel (never a wrong clean).
- Session cleanup: activity-based TTL sweep (sessions 3600s idle, pendings 120s);
reaping only removes expired entries and never affects another live session.
- account_sync now clears only stale pending for the machine (pre-launch hygiene);
it no longer resets a per-IP mode (there is no per-IP mode any more).
Backend-only: the launcher registration payload (already carries personaId) is
unchanged. Additive; P2 sentinel remains the else-branch and the default.
Tests: matrix A-Q incl. same-IP concurrent (K), same-IP+persona relaunch (L),
same-IP failed-patch (M), late-registration-vs-frozen-sessions (N), TTL expiry (O),
duplicate/idempotent registration (P), and register-before-login pending (Q).
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.

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.
