Runs the REAL roster_server.py under `sudo unshare -n` (so port 8081 is free and
production is never touched) and validates its certificate BY THE DIALED IP, proving the
before/after the SAN fix (fbc0da2) targets:
* OLD cert (DNS-only, production's current shape) -> a by-IP-verifying client is
rejected with "IP address mismatch, certificate is not valid for '127.0.0.1'" — the
certificate_unknown class the FIFA client hit.
* NEW cert (fixed generator, DNS + IP SANs) -> verifies through the actual roster
server and returns the roster XML (200, application/xml).
roster-cert-verify.py is the client probe (trusts the served self-signed cert as CA,
checks it against the dialed IP, then GETs /fifa17/fut/rosterupdate.xml).
roster-cert-iso-test.sh drives the real server with each cert and asserts new=pass,
old=fail. Two harness bugs were found and fixed while writing it (a shared /tmp log the
production run owns, and a subshell pid that left the first server alive so the "old"
probe hit a stale server presenting the new cert — the tell was "self-signed" instead
of "IP mismatch"), so the final before/after is clean.
Complements the in-process check: this exercises the production server code path, not a
hand-rolled server. Live production confirmation still needs the container rebuilt with
OPENFUT_ADVERTISE set (operator-gated).
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.
