The redirector was the only host that spoke TLS, so its TLS lived inside
it. The roster host needs the same listener, and that made the choice
explicit: share this code or copy it.
Copying it is what already went wrong. On 2026-08-11 the Rust redirector
served one certificate while the container served another. ProtoSSL
caches the server certificate per backend, so the redirector -- the first
TLS connection of a session -- decided what the client expected, and
every later service failed its handshake. Silently: Python's socketserver
swallows ssl.SSLError as OSError. Three gates went to it. One place to
configure TLS is the structural fix, so it exists before the second host
does rather than after.
Split along the line the architecture already draws:
openfut-tls how to build an acceptor. Game-independent.
Knows nothing about which suites any client
offers.
adapter-fifa17::tls what FIFA 17 was OBSERVED to offer: the six
enabled suites, the two refused, the TLS 1.2
window, the EA SNI. Plain strings, so the
adapter keeps its lean dependencies -- reading
a card table should not build OpenSSL.
redirector-host joins the two. Chooses no cipher of its own.
Behaviour is unchanged, and shown to be:
* tests/fifa17_tls_profile.rs carries over every case from the deleted
module -- FIFA's eight suites negotiate AES256-GCM-SHA384, each enabled
suite works alone, RC4-only is refused, ECDHE-only is refused. Deleting
a module must not quietly delete its evidence.
* one test pins the composed values literally against the host as it was
when gates 1-14 passed. A "pure refactor" that cannot fail is not a
claim, it is an assumption.
* the rebuilt binary self-tests to the same TLSv1.2 / AES256-GCM-SHA384
the retail client negotiated at 17:09 today.
Two improvements fall out of having one place to look:
* the startup banner now prints cert_sha256. The mismatch above raised no
error at startup and broke the client much later with nothing logged;
it is now the first line of the log.
* tls_min/tls_max print as TLSv1.2 rather than SslVersion(771). This line
is gate evidence and gets read by people.
Nothing deployed and nothing restarted: FIFA is mid-session on the
running redirector, which is untouched.

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.
Repositories

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.

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.
